Title: Flow control valve
Inventor: MITO AKIO
IPC: F15B13/043
Filed: 1992-05-22
Abstract: PURPOSE:To accurately compensate temperature by moving a flapper by while changing internal pressure along with the change in the viscosity of the pilot fluid which flows in a pressurized chamber and making a spool follow this movement to control the flow rate of a main circuit fluid. CONSTITUTION:Pilot fluid, when the temperature rises, its viscosity is lowered, increasing the flow rate of the fluid passing a choke type input throttle 17a, flows into a back pressure chamber 15. The pilot fluid discharged from a pressurized chamber 45 through an orifice type output is kept at a fixed resistance value regardless of temperature, thereby increasing the pressure of the fluid in the pressurized chamber 45 and pushes back a flapper 18. Then, the gap of a nozzle 44 is widened, and the back pressure of the nozzle is lowered, and moves a spool 3 in the same direction in association therewith. When the process is utilized for oil temperature control, the valve port of a main circuit fluid is widened, increasing cooling capacity. When the temperature of the pilot fluid is lowered, the viscosity increases to reduce the flow rate of the pilot fluid flowing into a back pressure chamber 15, and the pressure in the pressurized chamber 45 is lowered, and the spool 3 is displaced in the opposite direction and stands still at a new balanced position.

Abstract: PURPOSE:To automatically control the position of an inside welding torch with respect to the butt part position so that an optimum temperature state is always attained and to equalize the penetration quantity of both edge parts of a butt part by measuring a shape and a temperature distribution of the butt part from the outside at the same time. CONSTITUTION:The shape of the butt part 2 right after welding by the inside welding torch 3 is measured from the outside. At the same time, the temperature distribution in the vicinity of the butt part right after welding by the inside torch 3 is measured without contacting from the outside. Accordingly, a maximum point at this temperature distribution is regarded as the maximum penetration position of the butt part 2. Consequently, it is necessary to make this maximum penetration position coincident with the butt part 2. Conversely, when the position of the inside welding torch 3 is then controlled so that the maximum position of the measured temperature distribution is coincident with the measured butt part on a picture, both edge parts 2a and 2b of the butt part 2 are made to the maximum penetration positions. Accordingly, the penetration quantity of both edge parts 2a and 2b is equalized.
