A through space (24) is arranged between the side surface (21) of support insert (14) and lateral surfaces of casing (2). Water flows up to the outlet (49) through space (24).
EFFECT: better performances of the mixer.
The present invention relates to a sanitary water valve, namely to the standpipes device, mainly single lever mixer having a housing with at least one receiving hole for the water spout and located inside the housing of the regulating cartridge that connects input through the receiving hole of the water and which controls the flow of water to the spout in accordance with the position of the control arm, and regulating the cartridge on its lower side has at least one inlet and one outlet for water.
Plumbing pipes and fittings specified type known for over twenty years and available in the trade network in the most different variants of execution. In such a sanitary water valve is mainly applicable regulatory cartridges described in DE 2739587 C3. These cartridges all inlet and outlet for the water is located on the bottom side of the base that facilitates the tight connection of the cartridge casing pipes of the device. Then coming out of the cartridge water flows through a path in the base water device and thence falls into the spout. This type of design is particularly successful in cases where the spout joins the body of water device is istwa relatively small height, for ease of message passing cavity in the base water devices with a spout.
In recent years, the desire of producers to new accents in the forming of sanitary water fittings. This applies in particular to sanitary water valve with spout, made up or at the top. Supply to such a spout of water coming out of the cartridge in the direction from top to bottom, is technically quite complicated. To solve this problem in principle you could use cartridges with the outlet is not at the base and at the top. However, in this case, on the one hand, there are problems with sealing channels to carry water to the appropriate bushing cavity in the body of water device, and on the other hand, will need cartridges designed specifically for such valves. Aspirations producers of sanitary water fittings and those who installs it is intended that the number of components is as small as possible.
The problem to which the present invention is directed, is in the design of plumbing pipes of the device mentioned at the beginning of the description of the type which when using the standard regulatory cartridges would constructively Rostami measures to direct the flow of water to the spouts, located at the top or the upper part of the water.
This task is solved according to the invention due to the fact that
cartridge is located inside the supporting liner, having
at least one through hole that communicates on one side with the specified at least one receiving housing bore water device, and on the other hand - with the specified at least one inlet hole of the cartridge, and
another through hole that communicates on one side with the outlet of the cartridge, and on the other hand - with the water distribution cavity located between the base of the liner and casing pipes of the device and directing the flow of water in the external radius of the area of the internal space of the housing, and
between the side surface of the base liner and the side surface of the housing, limiting its interior space has a continuous cavity through which water can move up to the spout.
Thus, in the invention it is proposed to install the control cartridge is not directly in the interior of the body of water device, and a separate support insert or cap located as a kind of adapter between the housing and the cartridge. Between this base liner and founded the eating of the body of water device, as well as the side surface bounding the internal space of the housing, you can create channels for water movement required to change the direction of flow of the water exiting the cartridge down with the turn this thread up. While supporting the liner, at least on its individual areas, it is washed with water.
Between the outer side surface of the base liner and the side surface of the housing bounding the internal space, it is expedient to provide spacer ring, positioning a support insert and having a flow-through water extraction. This option is rational primarily in those cases where the internal cavity between the support pad and the side surface of the housing bounding an internal space of the last, must be circular. In this case, the spacer ring sets support insert on the radius of the housing so that the entire circumference of the lateral surface of the bearing liner formed slit-like internal cavity of constant thickness.
In a preferred embodiment of the invention in a through hole of the support liner, soobshayem with the outlet of the regulating cartridge, is the throttle that limits the amount of water passing through it per unit time, some limiting value (ogranichitel the flow). As a result, when fully opened, the regulating cartridge excluded changing the shape of the jet flowing water associated with changes in water pressure in the water distribution network connected to standpipes device.
The proposed invention in the design of plumbing pipes device is particularly suitable for spouts, made in the form of a bowl mounted on the top side water device. Such Cup-shaped spouts allow you to create a special aesthetic effect, and resulting from such spout a jet of water, forming the likeness of a water curtain, causing many users a pleasant feeling of comfort.
When this Cup it is advisable to position with tilt, providing the expiry of water over the edge of the bowl mainly in the limited angular intervals on its circumference. This approach allows to provide the desired in each case the length of the water curtain in the transverse relative to the longitudinal axis of the flow direction.
The Cup may have a penetration hole through which water flows from the bottom to the top of the bowl. Thus, in this embodiment, water enters the Cup-shaped spout is not in the side, and through the inner hole, which allows us to increase generated by the stream flowing from the spout of water aesthetic effect.
When santehnik the prioritization of water the device is a single lever mixer, relevant is the option through which the Cup is the control mechanism regulating the cartridge and the handle protrudes from the bowl up. Managing such a cartridge may, in principle, in a known manner, although made in the form of a bowl spout is, not counting the handle, the top structural member of the device.

The last moves, if you look at the drawing 1, clockwise down and its bottom located inside the cartridge 26 by the end of the regulatory moves puck in such a way that the cartridge 26 starts to pass water. The ratio of hot and cold water coming out of the cartridge 26, the flow of the mixed water is set by rotation, in other words, by changing the angular position of the swivel element 46 of the cartridge 26 by rotation of the support ring 39 around its own axis. The angular position of the support ring 39 is adjusted by appropriate rotation of the handle 37 of the control, in principle similar to the principle of the conventional single lever faucets.
The stream flowing out of the cartridge 26 of the mixed water first passes through the orifice 27, restricting the water flow. After passing through the orifice 27, the mixed water flows in the space provided in the base 15 of the insert 14 a through hole, and through it in the space provided at the bottom surface 11 of the housing 2, the recess 12 (water distribution cavity) and distributed by the latter in the circumferential direction. From the recesses 12 water enters the ring the entrance to the cavity 24 between the inner side surface of the housing 2 and the outer sides of the second surface 21 of the liner 14, and through made in the annular flange 31 of the threaded element 28 of the recess passes to push the ring 52. Then provided in the side surface 53 of the clamping ring 52 is made in the form of grooves, the grooves of water through the gap between the ring 52 and the wall provided in the Cup-shaped spout 49 through holes 50 enters the space under the membrane 55. The water pressure membrane 55 is lifted, allowing the water to flow on the upper surface of the Cup-shaped spout 49. Overrunning spout 49, water pours out from it down schematically shown in Fig.7. a broad stream, forming a kind of water curtain. When fully opened, the cartridge water device 1, in other words, after reaching the set limit water flow orifice 27, mounted in the manner prescribed in the liner 14 through the opening 18, avoids caused by pressure fluctuations in the supply valve shape changes resulting from the spout of the spout.
