Abstract
Disclosed is a pressure-adjusting mechanism comprising a pressure-adjusting handle, a pressure-adjusting screw for adjusting resilient force of a spring member by making rotation integrally with the pressure-adjusting handle, and a pressure-setting scale for indicating a preset pressure value by rotating the pressure-adjusting handle in a predetermined direction. As a result, it is possible to obtain the pressure-adjusting mechanism which is constructed integrally with a pressure control valve owing to a simple structure and which makes it possible to easily adjust the pressure by an operator.
Claims7
A pressure-adjusting mechanism constructed integrally with a pressure control valve, for adjusting a secondary pressure controlled by said pressure control valve, said pressure-adjusting mechanism comprising:
- a pressure-adjusting handle;
- a pressure-adjusting screw for adjusting resilient force of a pressure-adjusting spring by making rotation integrally with said pressure-adjusting handle, wherein said pressure-adjusting screw is provided displaceably in an axial direction and rotatably in a circumferential direction, and is fixed at an arbitrary position in said axial direction and in said circumferential direction by the aid of a fixing screw provided for said pressure adjusting handle;
- and
- a pressure indicating scale for indicating a preset pressure value by rotating said pressure-adjusting handle in a predetermined direction,
- wherein said pressure control valve comprises a flow-rate adjusting mechanism internally fitted and rotatably attached to a valve body of said pressure control valve.
