The front part of the lever of figure 10 are not shown.
These performance valves are designed for different variations of the excess pressure in the premises, and these models differ from each other diameters of through-holes duct, as well as the design decisions associated with these through holes.
Valve excess pressure is characterized by the presence of the cylindrical housing 1 (Fig 1) and pivotally connected with the casing of the rotary plates 2 located in the housing. The plate is connected to the frame by means of the lever 3 is rotated plates (figure 2). The upper end of the lever 3 is rotated plates rigidly connected with the plate, the lower end of the lever is made movable in the longitudinal direction of the valve fixed counterweight 4. The lever 3 pivotally connected with the housing 1. The valve is made with eccentric clamp 5 plates to the chassis. The clamp plate is installed on the housing 1 and the Cam 6. the false with the opportunity to interact with the lever 3 rotates the plate and can be locked in position when closed plate. The counterweight is made of two parts which are able to rotate relative to the lower part of the lever 3, or from one part. The counterweight 4 is installed on the bottom part of the lever 3 is movable relative to this part and with the possibility of fixing in a predetermined operating position. This contrast can be set to swivel on the lower part of the lever 3 and on form he can be rectangular, round, or elongated with a displaced center of gravity relative to the axis of rotation or to have any other form.
The lever 3 is rotated plates made -neck with front and lower parts 7 and 8, respectively, extending toward the plate. Rigid connection of the upper end of the lever 3 with the plate 2 is made by means of a detachable connection, the screw 9 which is screwed in is made at the rear side plate screw hole. The hinged connection of the lever 3 from the housing 1 is made by means of brackets 10 and 11 (figure 1), which are made on the body, and means located between the brackets of the front part 7 of the lever 3. The front part 7 of the lever is connected with the bracket adjusting screws 12 can be rotated front part 7 of the lever relative to the brackets 10 and 11 around the screws 12. The counterweight 4 (figure 2) is movable to lock installed in the groove 13, which is made in the lower part 8 rich the ha 3. Eccentric clamp 5 includes a Cam 6, -shaped lever 14 of rotation of the eccentric, the latter is rigidly fixed to the lever 14. The clamp also includes a latch 15 of the lever 14 and the Cam disk 6 in their working position. The lever 14 turning the Cam screw is located in the holes of the brackets 10 and 11, the Cam 6 is located between the brackets, bent vertical end of the lever 14 turning the Cam screw serves as a handle for turning the Cam screw and the other end of the lever 14 is made with a screw threaded, and screwed the latch lever 15. The latch cooperates with the surface 16 of the bracket 11.
The screw hole on the rear side 17 of the plate is made in serving the elongated portion 18 of the dish.
Fixing rolling counterweight 4 in the groove 13 of the lower part 8 of the arm 3 carried out by means of a screw 19, which is located in the holes in the counterweight and in the groove 13 of the lower ledge 8 of the lever 3. Opposed to 4 in different forms (figure 10) is connected by means of a screw 19 with the end of the lever 3 with the possibility of rotation around the screw and the fixation screw in a predetermined operating position.
On the housing 1 of the valve is fixed to the casing 20, to which is pivotally attached to the cover 21 with lots of holes 22. The housing is attached by bolts 23 to the flange 24 of the duct (not shown), the flange is fixed, for example, in the wall between what adeniyi (not shown).
The upper end of the lever 3 is rotated plates made with an eye 25, the hole which is pin 9 on the end of which is screwed a nut 26 for securing the lever 3 to the plate 2. Positions 27 and 28 shows the sealing strip.
The retainer 16 is fixed to the arm 29 for screwing the retainer 16 on the threaded end of the arm 14 of the lock 16. The Cam 6 engages with the lever 3.
Figure 4-9 shows other performances valves, identical to the first execution of the design of the overpressure valve, the lever 3 in the first performance of the valve are curved (figure 2), the levers 3 in other versions of the valve (Fig 3, 5, 7, 9) is made straightforward. Performance valves differ from each other through sections of the housings of the valves, the diameters of the plates, the mass balances and layouts designed for various working conditions with the specified ventilation systems.
Operates the valve excess pressure as follows.
Move the counterweight (2) in the slots 13 of the lower part 8 of the arm 3 and fix it on the lever by a screw 19 in a given estimated position, which is designed to actuate the valve when a certain excess pressure of the air to the right of the plate 2. Current position chosen by a calibrated line (not shown), which is located on the lower part 8 of the arm 3 is on the side of the screw 19. For more fine adjustment of the calculated position of the counterbalance one part or every part is made with offset screw 19 center of gravity, rotate around the screw 19 and regulate more precisely the moment of resistance of the rotation plates 2 from the action of the air. Fine adjustment is achieved by shifting the center of mass of each part of the counterweight relative to the lower part 8 of the lever. The angle of rotation of the parts of the counterbalance choose also calibrated scale (not shown)deposited on the lower part 8 of the arm 3.
If the counterweight 4 is the offset center of gravity and fixed on the lower end of the lever 3 with the possibility of fixation and rotation relative to the lever (figure 10), then the adjustment of the torque of the rotation plates 2 from exposure to air is realized by turning the counterweight 4 relative to the arm 3.
Next, the adjusting screws 12 regulate the ease of rotation of the lever 3 and the plate 2 in the housing 1 and after adjusting operations of the cover 21 is closed and valve alombert. When the pressure of the air to the right of the plate 2 (figure 2) air passes through the holes 22 of the cover 21 and exerts pressure on the plate 2 with its rear side 17. When the plate is rotated around the screws 12 and occupies the position shown in figure 3. Air passes from right to left chere is C the resulting window between the plate 2 and the housing 1, and after some time the pressure of the air before the valve (right) and in the premises after the valve (left) is aligned. The counterweight 4 creates torque and rotates the lever 3, and with it the plate 2 around the screws 12 in a clockwise direction, and the bore of the housing 1 is closed by a plate 2, the plate occupies the position shown in figure 2.
To the left of the plate 2 (figure 2) air through the valve into the room, located to the right of the plate, fails.
In terms of security, when required complete sealing of adjacent premises, manual plate 2 is pressed to the seat body 1 by rotating the Cam disk 6, which rotate the lever 14 counterclockwise. Then the lever and the Cam lock clamp 15 of their displacement, which turn the handle 29 and the clamp screw 15 on the threaded horizontally disposed portion of the lever 14. When the latch 15 of its surface is pressed against the surface 16 of the bracket 11. In the locked position of the eccentric 6, the valve is sealed and the air moving through it are excluded.
Similarly, work performance valve shown in figure 4-9.
Horizontal movement of the plates at the end of its stroke provides uniform compression of the sealing strip 27, which significantly increases the tightness of the valve and reliability it is work, providing a given level of tightness after prolonged operation of the valve. Improvement of these parameters is achieved through the application of relatively simple mechanism for moving and rotating the plate and layout solution valve, expressed by the set of essential features.
