Abstract
The utility model relates to an air valve, which comprises a valve body, a valve cover, a valve handle and a valve sheet, wherein one end of the valve handle is provided with external threads, the valve sheet is provided with a thread hole which matches the external threads, the valve body inner cavity is provided with a guide post and a relevant position on the valve sheet is provided with a guide hole. When the valve handle is rotated, the valve sheet is driven to make running top and bottom, a communication passage which blocks the connection between an air inlet and an air outlet is switched on, and as a result, the purpose of air exhaust and charge can be achieved. The air valve has the advantages of simple and convenient operation, and low cost, and doesn't leak easily. Besides, because the air valve is provided with a plurality of air outlets, the utility model can be inflated in a flow dividing type, and thus, the work efficiency is increased. In addition, the air inlet is provided with an edge protection apparatus, so the air inlet is not easy to damage.
Description
Technical field
The utility model relates to a kind of air valve, particularly a kind of employed novel flow deviding type air valves of inflation series products such as airbed, safety air cushion that are used for.
Background technique
Inflatable packer is widely used in family, field and sports center because of advantages such as its elasticity are strong, safe, comfortable.Final vacuum is used in inflation before using, and carries, collects conveniently, and be the special concern that the valve body of inflation pad exhaust just is subjected to people.According to reports, a kind of inflatable packer air valve is arranged, as Chinese patent CN03118977.6; " air permeable type high strength leakageproof multiform air cushion " by name discloses a kind of air valve, and the air cushion air valve of this structure is during inflation; unclamp the bolt that compresses valve block; spring backs down valve block, and suction port and air outlet passage are connected, owing to the elastic force by spring; suction port and air outlet communication passage can not reach sealing fully; gas leakage, and suction port unprotect device easily, fragile.
Summary of the invention
The purpose of this utility model is at above-mentioned existing problems and deficiency, and a kind of novel flow deviding type air valve is provided, its gas leakage easy and simple to handle, with low cost, difficult, high working efficiency.
The technical solution of the utility model is achieved in that
A kind of novel flow deviding type air valve, comprise valve body, valve gap, valve rod and valve block, valve gap is provided with suction port and several air outlets, valve rod one end that vertically the passes valve gap knob of ining succession, the other end is provided with outside thread, be provided with the tapped hole suitable with outside thread on valve block, body cavity is fixed with directional post, has on valve block and the corresponding pilot hole of directional post.
Be provided with valve block, diaphragm seal and seal ring between the utility model valve body and the valve gap from the bottom to top successively, seal ring is fixed on the valve block, have on the diaphragm seal with valve block on corresponding pilot hole, suction port is provided with the suction port safe edge, each air outlet is divided into the both sides of valve gap, can divide streamedly to air cushion inflation, valve body can be arbitrary shape.
Advantage of the present utility model:
1, the utility model rotary valve rod drives valve block by valve rod and moves up and down, just can connect and blocks the communication passage that suction port links to each other with the air outlet, fills the action that exhaust begins or stops thereby reaching, and operates very easy, with low cost and difficult gas leakage.
2, the air outlet has a plurality ofly, has improved working efficiency.
3, suction port is provided with the suction port edge plate device, and suction port is not fragile.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model decomposing schematic representation.
Schematic representation when Fig. 2 opens for the utility model air valve.
Schematic representation when Fig. 3 is the utility model air valve closure.
Embodiment
As shown in the figure, the utility model comprises valve body 1, valve gap 9, valve rod 12 and valve block 5; Be provided with seal ring 8 between valve body 1 and the valve gap 9, fix valve body 1 and valve gap 9 with screw 2; Valve rod 12 1 ends are provided with outside thread 10, and valve block 5 is provided with the tapped hole 16 suitable with outside thread 10, and valve rod 12 the other ends pass valve gap 9 and are furnished with knob 14; Be provided with diaphragm seal 6 between valve block 5 and the valve gap 9, and valve block 5 is fixed on the diaphragm seal 6, valve body 1 inner chamber is provided with directional post 3, is respectively equipped with pilot hole 4,7 correspondingly on valve block 5, the diaphragm seal 6, and valve block 5 and diaphragm seal 6 can only be moved up and down; Valve gap 9 is provided with suction port 13 and air outlet 11, and air outlet 11 is divided into the both sides of valve gap 9, and suction port 13 is provided with suction port safe edge 15.
The utility model working principle is:
During inflation, valve block 5 and diaphragm seal 6 are positioned at the bottom of valve body 1, the channel connection that suction port 13 links to each other with air outlet 11, and gas is by a plurality of pores of air outlet 11 two rows and to divide the streamed inflatable packer that enters.After air cushion is full of, rotary knob 14, knob 14 drives valve block 5 and upwards operation of diaphragm seal 6 by valve rod 12, and blocking-up suction port 13 and the passage that air outlet 11 links to each other make air cushion can not pass through the outside exhaust of air valve.
During exhaust, the rotary knob 14 that remains unchanged, knob 14 drives valve blocks 5 by valve rod 12 and moves downwards with diaphragm seal 6, connects suction port 13 and the connecting passage that air outlet 11 links to each other, and makes gas discharging outside filling up introversion.
