Problems solved by technology
However, the hole of the relief valve is small now, so after a period of work, the hole is often blocked, causing the entire regulating valve to fail to achieve the function of balancing pressure.
In addition, when the input air pressure is strong, the existing small holes cannot effectively deal with the input pressure, and the adjustment efficiency and adjustment range are limited

The invention discloses an air pressure regulating valve, a precision combination valve and a gas residual detection device for the precision combination valve. The air pressure regulating valve is increased from an original valve core to a There are two valve cores, and two air outlet channels are correspondingly opened on the valve seat. The opening and closing of the air outlet channel is adjusted through the adjustment assembly and the movable assembly. When exhausting, both valve cores can be exhausted, thereby increasing the air pressure range that the air pressure regulating valve can adjust, that is, the adjustment range and the adjustment efficiency.
Description
technical field [0001] The invention relates to a regulating valve, in particular to an air pressure regulating valve, a precision combination valve and a gas residual detection device for the precision combination valve. Background technique [0002] The regulating valve is all components used in hydraulic and pneumatic systems such as power components, control components, actuators, auxiliary components, etc. There are many types of regulating valves, which are widely used in various industries such as construction machinery, agricultural machinery, metallurgical mining machinery, plastic machinery and so on. As the key technology of transmission and control, regulating valve is the core technology and basic component technology widely used in the industrial field. [0003] The gas pressure regulating valve is a gas pressure control valve, which can act as a constant pressure relief, on the one hand, it can control the gas flow, and on the other hand, it can protect the s...
