Valve
专利汇可以提供Valve专利检索，专利查询，专利分析的服务。并且PURPOSE: To heighten the stability of a valve for changing a displacement into fluid pressure, by inserting a conical valve element from a convergent part selectively into or out of contact with a valve seat having a divergent part and shaped like a Venturi tube to easily change the gain.
CONSTITUTION: The cylindrical valve seat 1 has the divergent part 13 divergent rightward in Fig. and the convergent part 11 convergent rightward in Fig. The valve element 5 inserted into the valve seat 1 from the convergent part 11 is shaped like a cone with a vertical angle of 6 to 10° not to disturb fluid flow. Feed air pressure P
s introduced through an inlet pipe 3 is changed into output air pressure P
o , which is taken out from an output pipe 4. The air pressure P
o falls gradually according as the cross-sectional area of opening between the valve element 5 and the valve seat 1 is increased. The linear part of curve of the output air pressure P
o between the feed pressure P
s and the zero pressure 0 is lengthened, while the non- linear part is shortened. Therefore, the stability of the valve is heightened
