Definitions
- the present invention relates to a fluid control valve and a diaphragm valve that can be suitably used as a shutoff valve for opening and closing a high-pressure or high-temperature fluid.
- a valve body having a fluid flow rate, a diaphragm that abuts / separates from the valve seat to open / close the flow path, and a diaphragm retainer that presses the diaphragm.
- Patent Document 1 An actuator that moves the water up and down.
- the operating pressure is applied by supplying operating air to the built-in actuator. Since thrust (pushing pressure) repeatedly acts between the valve seat and the diaphragm (seal portion) as the flow path opens and closes, its durability is important.
- a control valve that opens and closes a high-pressure fluid generally has a metal seal structure in which the valve seat formed on the valve body and the diaphragm in contact with the valve seat are both made of metal, but the valve seat or the valve body has a metal seal structure. Scratches not only shorten the life of the valve, but also generate fine particles of these members from the contact surfaces of the valve seat and diaphragm, which are mixed into the fluid to be processed passing through the valve. It also causes contamination of the fluid to be treated.
- An object of the present invention is to provide a control valve having excellent durability performance without being restricted by applications such as high pressure and high temperature, and suppressing the generation of particles.
- a valve body having an inflow passage and an outflow passage for fluid and a valve seat formed on the periphery of the inflow passage in the valve body are brought into contact with and separated from the valve seat.
- a diaphragm that communicates and shuts off the inflow passage and the outflow passage, a diaphragm retainer that presses the central portion of the diaphragm, and an actuator that moves the diaphragm retainer are provided, and a closing pressure between the valve seat and the diaphragm is provided.
- It is a diaphragm valve having an adjustment mechanism for adjusting the pressure to a predetermined pressure.
- the thrust acting between the diaphragm and the valve seat when the flow path is closed can completely close the flow path even if the pressure on the inflow passage side and the pressure on the outflow passage side change. It was set to a value that could be achieved (maximum thrust), and even if the pressure on the inflow passage side and the pressure on the outflow passage side changed, the maximum thrust always acted.
- the thrust acting between the diaphragm and the valve seat (closing the valve) when the flow path is closed responds to the change when the pressure on the inflow passage side changes. , Adjusted to an appropriate value that can completely close the flow path.
- the closing pressure is the pressure applied to the diaphragm to stop the flow of fluid. If an excessive closing pressure is applied to the contact surface between the diaphragm and the valve seat, the contact surface will be finely scratched, which may shorten the life of the valve. Since fine particles may be generated from the contact surface, if the fine particles are mixed with the fluid to be processed passing through the valve, the fluid to be processed will be contaminated.
- the shape of the flow path (in which direction the pressure on the inflow passage side is acting) is taken into consideration, and whether the type is always open or always closed is taken into consideration. Therefore, the closing pressure between the valve seat and the diaphragm is controlled to be an appropriate pressure.
- the present invention (2) is characterized in that the predetermined pressure is in the range of 105 to 140% of the pressure on the upstream side of the diaphragm when the diaphragm is in contact with the valve seat (2). This is the diaphragm valve of 1).
- the inventors of the present invention have repeated many experiments, and in a valve having a metal diaphragm and a metal valve seat, scratches generated on the contact surface between the diaphragm and the valve seat and particles generated by repeated opening and closing of the valve. It was found that the amount of was related to the closing pressure of the valve. This discovery led to the present invention.

- an urging member such as a spring
- the closing pressure acting between the diaphragm and the valve seat is not adjusted.
- the closing pressure acting between the diaphragm and the valve seat can be adjusted by the adjusting mechanism.
- the diaphragm retainer In a normally closed type diaphragm valve, the diaphragm retainer is moved by a spring, so it is possible by providing a movable member that adjusts the amount of deflection of this spring.
- the pressure of the fluid flowing through the valve depends on the intended use of the valve and may vary from day to day, even for the same valve installed. At that time, if the pressure of the fluid flowing through the valve is low, the amount of deflection of the spring is reduced, and if the pressure of the fluid flowing through the valve is high, the amount of deflection of the spring is increased to adjust the closing pressure of the diaphragm valve. It becomes possible to do.
- the diaphragm valve is a normally open type that is normally open, and the actuator urges a piston connected to the diaphragm retainer and the piston in the closing direction of the valve.

- the closing pressure acting between the diaphragm and the valve seat is not adjusted.
- the closing pressure acting between the diaphragm and the valve seat can be adjusted by the adjusting mechanism.
- the diaphragm retainer In a normally open type diaphragm valve, the diaphragm retainer is moved by a piston in the actuator, and this piston is moved by a fluid pressurizing mechanism that urges the valve in the closing direction.
- the fluid pressurizing mechanism drives the piston by flowing operating air or the like to apply pressure to the piston. By adjusting the pressure of the fluid flowing through the fluid pressurizing mechanism, the closing pressure can be adjusted.
- the pressure of the fluid flowing through the valve differs depending on the purpose of use of the valve, and even if the same valve is installed, it may differ from day to day. At that time, if the pressure of the fluid to be processed flowing through the valve is low, the pressure flowing through the fluid pressurizing mechanism is reduced, and if the pressure of the fluid to be processed flowing through the valve is high, the pressure of the fluid flowing through the fluid pressurizing mechanism is reduced. It becomes possible to adjust the closing pressure of the diaphragm valve by increasing.
