Abstract

The utility model discloses a kind of unidirectional gas circuit automatic-sealed improved structure, including body, air inlet, gas outlet, non-return piece and negative pressure channel, the air inlet, gas outlet are separately positioned on body and spaced certain distance, described non-return piece in body and air inlet is inserted at top, the negative pressure channel is arranged on body side and including negative pressure air-out through hole and negative pressure exhaust passage, the negative pressure air-out through hole is arranged on below negative pressure exhaust passage and both connections, the negative pressure exhaust passage are up big and down small tower-like；Body is set to form negative pressure generation negative pressure by increasing negative pressure channel, the non-return piece of sealing that automatically resets under negative pressure effect is simple to operate, it is low without using spring cost, efficiency of assembling is high, is hardly damaged service life length, is more convenient without frequently replacing operation of components.

Description

A kind of unidirectional gas circuit automatic-sealed improved structure

Technical field

The utility model belongs to pump valve seal field, and more particularly to a kind of automatic-sealed for unidirectional gas circuit improves knot Structure.

Background technology

Many in pump valve body is all unidirectional gas circuit, when inflating completion and needing to protect gas needs inlet close to seal, into It is by non-return piece of completion that gas port, which closes sealing, and non-return piece is not completely attach to sealing with air inlet in inflation, during sealing Non-return piece is then needed to be completely attached to air inlet, this process just needs non-return block reset, and at present, non-return block reset is Completed by spring（As shown in Figure 3）, it is this to meet certain requirement by way of spring reset sealing, But there is also it is larger the defects of, overall structure is of high cost, assemble trouble efficiency it is low, spring use a period of time after it is vulnerable, Service life is short, frequently replaces the inconvenience of spring troublesome operations.

The technical problem to be solved by the present invention is to provide a kind of holistic cost is low, assembling is simply efficient, is not required to frequency Numerous replacement component, service life be long, easy to operate simple and direct automatic-sealed improved structure.

Utility model content

For the above-mentioned prior art overall structure of solution is of high cost, assembling trouble efficiency is low, using vulnerable after a period of time The problems such as service life is short, frequent replacement component troublesome operations are inconvenient, the utility model adopts the following technical solution：

The utility model provides a kind of unidirectional gas circuit automatic-sealed improved structure, including body, air inlet, gas outlet, only Inverse block and negative pressure channel, the air inlet, gas outlet are separately positioned on body and spaced certain distance, described non-return piece In body and top insertion air inlet, the negative pressure channel are arranged on body side and are arranged including negative pressure air-out through hole and negative pressure Gas passage, the negative pressure air-out through hole is arranged on below negative pressure exhaust passage and both connections, and the negative pressure exhaust passage is upper big Under it is small tower-like.

The beneficial effects of the utility model are：Body is set to form negative pressure generation negative pressure by increasing negative pressure channel, only Inverse block automatically resets sealing under negative pressure effect, simple to operate, efficiency of assembling height low without using spring cost, no Fragile service life length, is more convenient without frequently replacing operation of components.

Brief description of the drawings

Fig. 1 is the structure diagram under a kind of embodiment inflated condition of the utility model.

Fig. 2 is the structure diagram under non-return piece of automatic-sealed state.

Fig. 3 is the structure diagram that tradition is sealed by spring reset.

Embodiment

Describe the preferred embodiment of the utility model in detail below in conjunction with the accompanying drawings.

Please refer to Fig.1, Fig. 2, a kind of unidirectional gas circuit automatic-sealed improved structure, including body 1, air inlet 2, gas outlet 3, Non-return piece 4 and negative pressure channel 5, the air inlet 2, gas outlet 3 are separately positioned on body 1 and spaced certain distance, fills Inlet charge gas outlet outlet completes inflation operation during gas, and described non-return piece 4 in body 1 and air inlet 2 is inserted at top, The negative pressure channel 5 is arranged on 1 side of body and leads to including negative pressure air-out through hole 51 and negative pressure exhaust passage 52, the negative pressure air-out Hole 51 is arranged on the lower section of negative pressure exhaust passage 52 and both connections, the negative pressure exhaust passage 52 be it is up big and down small tower-like, by Negative pressure channel is increased on the basis of original structure, body is formed negative pressure when sealing is desired and produces negative pressure, non-return piece in negative pressure Automatically reset sealing under power effect, simple to operate, and low without using spring cost, efficiency of assembling is high, is hardly damaged use Cycle is grown, and is more convenient without frequently replacing operation of components.

The product form and style of above-described embodiment and schema and non-limiting the utility model, any technical field The appropriate change or modification that those of ordinary skill does it, all should be regarded as not departing from the patent category of the utility model.
