Abstract
The invention relates to an anti-corrosion one-way valve. The anti-corrosion one-way valve is characterized by comprising a stainless steel valve body, an air inlet end nut arranged at the front end of the stainless steel valve body, an air outlet end nut arranged at the rear end of the stainless steel valve body and a valve element arranged in a containing cavity in the stainless steel valve body; an O-shaped sealing ring is arranged on the outer circumference of the front end of the valve element, a circle of boss for jacking the O-shaped sealing ring is arranged on the outer circumference of the front end of the valve element, the interval between the boss and the front end of the valve element is half of the thickness of the O-shaped sealing ring, and a stainless steel spring making the valve element closed is arranged between the rear end of the valve element and the tail of the containing cavity. By the adoption of the stainless steel valve body and the stainless steel spring, corrosion resistance of the one-way valve is greatly improved, and meanwhile the sealing performance of the one-way valve can be effectively guaranteed through the sealing ring.
Description
Technical field
The present invention relates to a kind of corrosion-resistant one-way valve.
Background technique
One-way valve is used in pipe container, for limiting pressure or the flow direction, general one-way valve is made up of pipeline, ball sealer, spring and cone structure, when pipeline one end pressure is large, backs down the spheroid at taper hole place, make valve body conducting, when reverse pressure is large, taper hole is sealed by ball, forbids that fluid passes through, complete one-way conduction.Common one-way valve structures is complicated, there is the problem such as wear and leakage and spring failure.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of technological scheme of corrosion-resistant one-way valve.
Described a kind of corrosion-resistant one-way valve, the spool that it is characterized in that comprising stainless steel body, be arranged on the inlet end nut of stainless steel body front end, be arranged on the outlet side nut of stainless steel body rear end, be arranged on placed cavity in stainless steel body, the excircle of described spool front end is provided with O-ring seals, described spool fore end outer circumference is provided with the boss that a circle withstands O-ring seals, the spacing of described boss and spool front end is the half of O-ring seals thickness, is provided with the stainless steel spring that spool is closed between the rear end of described spool and placed cavity afterbody.
Described a kind of corrosion-resistant one-way valve, it is characterized in that the front portion of described spool has the perpendicular through hole perpendicular to axis, the cross-drilled hole being communicated with perpendicular through hole and stainless steel body air outlet hole is also had in described spool, the diameter of described spool front portion is less than the diameter of placed cavity, the described diameter at spool rear portion and the equal diameters of placed cavity.
Described a kind of corrosion-resistant one-way valve, it is characterized in that described spool rear portion has providing holes, one end of described stainless steel spring withstands in providing holes, and the other end of described stainless steel spring withstands on the back plane of placed cavity.
The present invention adopts stainless steel body and stainless steel spring, greatly increases the corrosion resistance of one-way valve, simultaneously seal ring the sealing that effectively can ensure one-way valve is set.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with Figure of description, the present invention will be further described:
A kind of corrosion-resistant one-way valve, comprise stainless steel body 1, be arranged on the inlet end nut 2 of stainless steel body 1 front end, be arranged on the outlet side nut 3 of stainless steel body 1 rear end, be arranged on the spool 4 of placed cavity 6 in stainless steel body 1, the excircle of described spool 4 front end is provided with O-ring seals 5, described spool 4 fore end outer circumference is provided with the boss 8 that a circle withstands O-ring seals 5, described boss 8 and the spacing of spool 4 front end are the half of O-ring seals 5 thickness, the stainless steel spring 7 that spool 4 is closed is provided with between the rear end of described spool 4 and placed cavity 6 afterbody, the front portion of described spool 4 has the perpendicular through hole 9 perpendicular to axis, the cross-drilled hole 10 being communicated with perpendicular through hole 9 and stainless steel body 1 air outlet hole is also had in described spool 4, the diameter of described spool 4 front portion is less than the diameter of placed cavity 6, the described diameter at spool 4 rear portion and the equal diameters of placed cavity 6, described spool 4 rear portion has providing holes 11, one end of described stainless steel spring withstands in providing holes 11, the other end of described stainless steel spring withstands on the back plane of placed cavity 6.
The present invention adopts stainless steel body 1 and stainless steel spring, greatly increase the corrosion resistance of one-way valve, simultaneously O-ring seals 5 the sealing that effectively can ensure one-way valve is set, the rear portion of spool 4 can ensure that spool 4 is always straight line motion in running, prevents spool 4 from running and occurs offseting and cause the problem that cannot seal.
