Abstract
The utility model discloses a kind of distributing valves of pneumatic diaphragm pump, it include valve deck and sliding block, the valve deck is equipped with air inlet, is covered with sliding block cover above the sliding block and sliding block is free to slide in sliding block cover, and the sliding block cover is equipped with spring, wherein one end is against on valve deck inner wall the spring, the other end is connected on sliding block cover, and spring is increased to lower section sliding block cover pressure, and sliding block still can be free to slide below sliding block cover, not only achieve the purpose that commutation, but also can reinforce sealing.
Description
Technical field
The utility model relates to pump accessories field, the specifically distributing valve of pneumatic diaphragm pump.
Background technique
The working principle of pneumatic diaphragm pump is horizontally slipping by distribution valve slider, to reach the commutation of distributing valve, in turn
So that air-flow is constantly changed direction, pushes the reciprocating motion of diaphragm.When distribution valve slider horizontally slips, since sliding block lower part has
Air pressure and gap exist, and Inlet Position be easy to cause the floating of sliding block in the side of distributing valve, can generate air-flow to sliding block top
Ejection so as to cause the floating of sliding block, and then influences the leakproofness of sliding block.
Summary of the invention
The purpose of this utility model: in order to overcome the drawbacks of the prior art, the utility model provides a kind of structure design
Rationally, the distributing valve of the pneumatic diaphragm pump of good airproof performance.
The technical solution of the utility model includes: include valve deck and sliding block, the valve deck is equipped with air inlet, on the sliding block
Side is covered with sliding block cover and sliding block is free to slide in sliding block cover, and the sliding block cover is equipped with spring, and the spring wherein support by one end
On valve deck inner wall, the other end is connected on sliding block cover.
By adopting the above technical scheme, spring is increased to lower section sliding block cover pressure, and sliding block still can be with below sliding block cover
Free to slide, position limiting slide block, anti-limited slip block is ejected by air-flow, alleviates the levitation of sliding block, not only achievees the purpose that commutation, but also can
To reinforce sealing.
The further setting of the utility model: air inlet is set to valve deck side and offsets position close to spring and valve deck
It sets.
Using above-mentioned further setting, change original Inlet Position, air-flow enters from valve deck side, can push down sliding block
Cover, further enhances the leakproofness of sliding block.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model specific embodiment；
Wherein, valve deck 1, sliding block 2, air inlet 11, sliding block cover 3, spring 4.
Specific embodiment
The distributing valve of pneumatic diaphragm pump as shown in Figure 1 includes valve deck 1 and sliding block 2, and valve deck 1 is equipped with air inlet 11,
It is covered with sliding block cover 3 above sliding block 2 and sliding block 2 is free to slide in sliding block cover 3, sliding block cover 3 surrounds the top surface and two sides of sliding block 2
The a part in face, sliding block cover 3 are equipped with spring 4, and wherein one end is against on 1 inner wall of valve deck spring 4, and the other end is connected to sliding block cover
On 3.When sliding block 2 is free to slide below sliding block cover 3, the utility model makees the movement that commutates, and spring 4 applies pressure to lower section
Sliding block cover 3, pressure increase, the leakproofness enhancing of sliding block 2.
Air inlet 11 is set to 1 side of valve deck and offsets position close to spring 4 and valve deck 1, air-flow from 1 side of valve deck into
Enter, sliding block cover 3 can be pushed down through 1 foot passage of valve deck, further enhance the leakproofness of sliding block 2.
