Description
Technical field
The utility model relates to one-way valve technical field, particularly relates to a kind of novel high-pressure air pump breather check valve.
Background technique
High-pressure pump is applied to every field, and as fire-fighting, industrial gas, diving etc., one-way valve is the strength member of high-pressure pump, and under long term high temperature, high pressure, high-frequency harsh conditions, the quality of one-way valve affects the main cause that air pump normally works; The one-way valve that prior art mesohigh air pump uses mainly is divided into two kinds, valve plate-type and sealing ring type, what valve plate-type adopted is rigid material, poor sealing, more affect if simultaneously have fine impurity to enter, although and the sealing of sealing ring type is better, the long-term high frequency of seal ring is beated and is made the life-span not long, and very easily aging in hot environment, need often change.
Model utility content
For solving the problems of the technologies described above, the utility model provides a kind of sealing effect better, the novel high-pressure air pump breather check valve that working life is longer.
A kind of novel high-pressure air pump breather check valve of the present utility model, comprise valve body and spool, described valve body is provided with the inlet hole communicated and air flue, described spool comprises valve rod, sealing gasket, Returnning spring and fixed block, described valve rod is through described air flue, the top of described valve rod is connected with one end of Returnning spring by fixed block, the other end of described Returnning spring is fixed in described inlet hole, the bottom of described valve rod is fixedly connected with described sealing gasket, and described sealing gasket is high temperature resistant polytetrafluoroethylsealed sealed pad.
Further, the difference of the internal diameter of described air flue and the diameter of valve rod is 0.01-1mm.
Further, the internal diameter of described inlet hole is greater than the internal diameter of described air flue, and the top of described Returnning spring is connected with fixed block, and the bottom of described Returnning spring is fixed on the top of described air flue.
Further, described fixed block is non-standard screw.
Further, the top of described valve body is also provided with cylinder cap, and the external diameter of described cylinder cap is greater than the external diameter of described valve body, and described cylinder cap and described valve body are structure as a whole.
Compared with prior art the beneficial effects of the utility model are: valve rod and valve interior wall gap are 0.01-1mm, and the gas of being come by low-pressure cylinder enters high pressure cylinder by this gap, and gas circuit is extremely short, considerably increase working efficiency and the compression ratio of air pump; Sealing material is tetrafluoro high-temperature sealing material, lower than valve block hardness, higher than seal ring hardness, fine impurity can not affect the normal work of one-way valve, also can normally work under 300 degree of high temperature, experiment proves the high-pressure pump breather check valve of this structure, tests after 2 years, still keep normal work, substantially increase working life than other kind one-way valve.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of novel high-pressure air pump breather check valve of the present utility model, comprises valve body 1 and spool, valve body 1 is provided with the inlet hole 11 and air flue 12 that communicate, the top of valve body 1 is also provided with cylinder cap 13, and the external diameter of cylinder cap 13 is greater than the external diameter of valve body 1, and cylinder cap and valve body are structure as a whole; Spool comprises valve rod 21, sealing gasket 22, Returnning spring 23 and fixed block 24, valve rod is through air flue, the top of valve rod is connected with one end of Returnning spring by fixed block, the other end of Returnning spring is fixed in inlet hole, the bottom fixed connection and sealing pad of valve rod, sealing gasket is high temperature resistant polytetrafluoroethylsealed sealed pad; The difference of the internal diameter of air flue and the diameter of valve rod is 0.01-1mm; The internal diameter of inlet hole is greater than the internal diameter of air flue, and the top of Returnning spring is connected with fixed block, and the bottom of Returnning spring is fixed on the top of air flue; Fixed block is non-standard screw, by screwing retaining screw, can adjust sealing intensity.
Valve rod and valve interior wall gap are preferably 0.1mm, and the gas of being come by low-pressure cylinder enters high pressure cylinder by this gap, and gas circuit is extremely short, considerably increase working efficiency and the compression ratio of air pump; Sealing material is tetrafluoro high-temperature sealing material, lower than valve block hardness, higher than seal ring hardness, fine impurity can not affect the normal work of one-way valve, also can normally work under 300 degree of high temperature, experiment proves the high-pressure pump breather check valve of this structure, tests after 2 years, still keep normal work, substantially increase working life than other kind one-way valve.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; if can also make in improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
