Furthermore, the pressing mechanism comprises a return spring and a pressing plate, the pressing plate is attached to the periphery in the valve body, the valve core is fixed to the lower end face of the pressing plate, and the return spring is sleeved on the surface of the valve core.
Furthermore, the valve also comprises a sealing element which is sleeved on the surface of the valve core and is positioned below the valve body.
Furthermore, a compression spring is further arranged in the valve body, an adjusting screw rod penetrating through the valve body is arranged on the upper end face of the valve body, and the end part of the compression spring is connected with the adjusting screw rod and the lower pressing plate respectively.
Furthermore, a hand wheel is arranged at the upper end of the adjusting screw rod.
The beneficial effects of the utility model reside in that:
the utility model discloses include valve body and case, the side of valve body has the blow vent, so, injects the air into by the blow vent and utilizes atmospheric pressure to exert pressure to the holding down plate until holding down plate compression hold-down mechanism, and the holding down plate pushes down the process and drives the case and remove and then seal the through-hole to the realization is to fluid seal's effect, can know from this, has solved the problem that the circuit board received the moisture and damaged in the background art through pneumatic mode.

Detailed Description
Referring to FIG. 1, the present invention relates to a pneumatic valve, comprising
The valve seat comprises a valve seat 1, wherein a channel penetrating through the surface of the valve seat 1 is formed in the valve seat 1, and through holes are formed in two sides of the channel;
the valve body 4 is arranged on the surface of the valve seat 1, the side face of the valve body 4 is provided with a vent 5, a pressing mechanism and a valve core 6 are arranged inside the valve body 4 and located below the vent 5, one end of the valve core 6 is fixed below the pressing mechanism, and the other end of the valve core 6 is inserted into the channel and abutted to the through hole.
The utility model discloses a theory of use as follows:
the utility model discloses include valve body 4 and case 6, the side of valve body 4 has vent 5, so, it utilizes atmospheric pressure to exert pressure to pushing down the mechanism and offsets until the bottom of pushing down mechanism and passageway to inject air into by vent 5, and pushes down the mechanism and push down the process and drive case 6 and remove and then seal the through-hole in to the passageway to the realization is to fluid seal's effect, can know from this, has solved the problem that the circuit board received the moisture and damaged among the background art through pneumatic mode.
It can be understood that the through holes on the two sides of the channel are respectively the water filling port 2 and the water outlet 3, so that the fluid enters the channel from the side of the water filling port 2, air is filled into the air vent 5, the valve core 6 moves in the channel, and the outer wall of the valve core 6 seals the water filling port 2.
It should be noted that there is a gap between the side surface of the valve element 6 and the water outlet 3, so that fluid overflowing during the pressing-down process flows out through the water outlet 3.
It is further explained that the air pump is also included, and the air pump is communicated with the air vent 5 through an air pipe.
Furthermore, the pressing mechanism comprises a return spring 8 and a lower pressing plate 7, the lower pressing plate 7 is attached to the periphery in the valve body 4, the valve core 6 is fixed to the lower end face of the lower pressing plate 7, and the return spring 8 is sleeved on the surface of the valve core 6; in the actual use process, inject atmospheric pressure into blow vent 5, utilize atmospheric pressure to make holding down plate 7 push down case 6 until case 6 offsets with the bottom of passageway, push down in-process compression reset spring 8, stop the gas supply in valve body 4 to blow vent 5 so, reset spring 8 resets and jack-up case 6, water filling port 2 communicates with the passageway once more.
Further, the valve further comprises a sealing element 9, the sealing element 9 is sleeved on the surface of the valve core 6 and is positioned below the valve body 4, fluid is attached to the surface of the valve core 6 in the lifting process, and the fluid can be effectively prevented from flowing out of the outside from the valve core 6 through the sealing element 9.
It should be noted that the sealing member 9 does not move with the movement of the valve element 6, and it is understood that the sealing member 9 is disposed between the valve body 4 and the valve seat 1, and the valve element 6 passes through the sealing member 9 into the passage.
Furthermore, a compression spring 10 is also arranged in the valve body 4, an adjusting screw rod 11 penetrating through the valve body 4 is arranged on the upper end face of the valve body 4, and the end part of the compression spring 10 is respectively connected with the adjusting screw rod 11 and the lower pressing plate 7; through the above design, when the air supply is insufficient, the valve core 6 can be manually adjusted, specifically, the clockwise adjusting screw 11 presses the compression spring 10 to enable the lower pressing plate 7 to descend or rotate anticlockwise to disperse the pressure of the adjusting screw 11 on the lower pressing plate 7, and the reset spring 8 jacks up the lower pressing plate 7.
It should be noted that, in the non-operating state, the compression spring 10 is kept in the compressed state, and then, in the pneumatic control, the compression spring 10 moves through the lower pressing plate 7 to enter the natural state from the compressed state.
Further, a hand wheel 12 is arranged at the upper end of the adjusting screw rod 11; the design can improve the comfort level of adjusting like this, is favorable to improving and adjusts efficiency.
