[0002] Pneumatic valve components on medium and large equipment in the prior art mostly adopt gate-type installation and sealing structure. The most common structural device is a pneumatic valve with double gate structure, or a rotary double gate pneumatic valve. This structure mainly uses The gate structure seals the valve port. Usually the gate needs to be tightly pressed by the pressure spring on the valve housing to achieve airtight sealing; the traditional structure is more troublesome to operate, and the structure is more complicated. When installing double gates, it must be The gate plate, the pressure spring and the shell are installed in coordination; in addition, the existing valve assembly will be subject to greater resistance due to the pressure of the intake pipe when it is opened and closed, especially when the valve port is about to close. The resistance is the largest, and the existing equipment, whether it is a push-pull or gate-type structure, cannot normally eliminate this resistance, which will lead to structural instability and potential safety hazards

Embodiment Construction
[0011] The present invention will be further illustrated below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0012] Such as figure 1 As shown, a valve assembly with its own pressure relief structure includes an inlet valve body 1 and two outlet valve bodies 2 communicating with the inlet valve body 1; the front ports of the two outlet valve bodies 2 Two sealing plates are also installed respectively, the sealing plate on the front side is set as the first sealing plate 3, the sealing plate on the rear side is set as the second sealing plate 4, and the first sealing plate 3 and the second sealing plate 4 on both sides There are valve ports 5 on both sides, the size of the valve port 5 on the fi...

The invention discloses a valve assembly with a pressure relief structure. The valve assembly comprises an air inlet valve body and two air outlet valve bodies communicating with the air inlet valve body. The two outlet valve bodies are symmetrically arranged in the shape of "L", a sealing vertical plate is installed at each of the ports of the two outlet valve bodies, and the lower ends of the sealing vertical plates on both sides are respectively provided with a valve port, the lower end edges of the valve ports extend to the transverse edges of the outlet valve bodies correspondingly, and the upper ends of the valve ports are arranged as oblique conical edges correspondingly. According to the device, through the design of the conical inclined surfaces, the valve can be opened and closedto achieve the purpose of automatic pressure relief, and do not bear great resistance and pressure when gradually closed.
