PURPOSE:To exactly control the opening an closing of a valve body according to the change of temperatures by using a system in which the valve body is operated by means of the warping deformation of a bimetal plate with the change of temperatures. CONSTITUTION:A casing 1 is provided with an inlet 2 and an outlet 3 for a fluid, e.g., paint, etc., and a valve seat 4 and a valve body 5 of a ball form are provided to the inlet 2. A diaphragm 6 is moved vertically by a competitive action between a pressure regulating spring 7 and the pressure of a fluid pathway on the outlet 3 side. The valve body 5 of the valve seat 4 is pressed through a valve lever 8 and a valve pressing plate 10 by means of the warping deformation of the bimetal 9 with change in temperatures. Thus, the discharge pressure of fluid on the outlet 3 side can be adjusted according to the change in the usual fluid pressure, and the control of the valve can be performed according to the variation in temperatures. |
