Abstract
The invention relates to a low flow resistance air channel one-way valve which is structurally characterized in that an inlet is formed in one end of a shell, an outlet pipe nozzle is arranged at the other end of the shell, a chamfered step is arranged on the inner wall of the shell and at an inlet end, a valve spool is abutted to a chamfer, and a spring is arranged between the valve spool and the inner wall of the outlet pipe nozzle. The air channel one-way valve is suitable for working in a low-pressure air channel, the working pressure of the valve is lower than or equal to 0.2MPa, the opening pressure is lower than or equal to 0.002MPa, and flow resistance is lower than or equal to 0.002MPa. Pressure loss of the air channel is decreased as far as possible by the ultra-low opening pressure and flow resistance, and reverse sealing requirements are effectively met by a 'metal-nonmetal' sealing form.
Description
Technical field
The present invention relates to a kind of one-way valve, relate in particular to a kind of low flow resistance air passage one-way valve for low pressure air-channel system, belong to valve class technical field.
Background technique
One-way valve structures is simple, is widely used, and almost in various pneumatic, hydraulic control systems, all has use.In different systems, for different needs, the parameters such as the working pressure of one-way valve, cracking pressure, flow resistance and reverse seal request are different.For low pressure air-channel system, low cracking pressure and low flow resistance are the important indicators that one-way valve must guarantee, be also that the technical barrier solving is thirsted in related domain always, but one-way valve of the prior art are difficult to meet above-mentioned requirements.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, a kind of low flow resistance air passage one-way valve is provided, solved in prior art one-way valve opens pressure high, the problem that flow resistance is large,
Technological scheme of the present invention is as follows:
One end of housing arranges import, and the other end of housing arranges outlet ozzle, and the inwall of housing arranges band chamfering step at entrance point, and spool and chamfering offset, and between spool and the inwall of outlet ozzle, spring is set.
Described spool is horizontal U-shaped.
Described U-shaped spool inwall is provided with boss.
Described spool material is polyimide plastic.
Between described housing and outlet ozzle, be provided with packing ring.
Described gasket thickness is adjustable.
Described packing ring is fine aluminium packing ring.
Described spring material is Stainless Steel Wire.
Advantageous effect of the present invention is as follows:
1, spool adopts polyimide plastic manufacture, and density is little, and intensity is high, and friction factor is low, good airproof performance, and spool is lightly flexible, can realize fast and open and close.
2, spring curls up than height, and rigidity is little, can make spool open under low-force.
3, it is optional that packing ring is provided with multiple different thickness, in order to adjust the pretightening force of spring, guarantees to open pressure and meet the requirements.After spool is opened, air-flow path is smooth and easy, there is no too small throttleng surface, and therefore flow resistance loss is very little, can meet the demands.
4, housing and outlet ozzle material are aluminum alloy material; Spool is made up of polyimide plastic, and packing ring is fine aluminium packing ring, and spring is manufactured by rustproof spring steel silk.The seal form of " metal-nonmetal " has guaranteed reverse seal request preferably.
5, to open pressure low in the present invention, and flow resistance is little, is arranged in air-channel system the pressure loss little, can be good at meeting the job requirement of low pressure air-channel system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1, housing, 2, spool, 3, spring, 4, packing ring, 5, outlet ozzle.
Embodiment
Referring to accompanying drawing, in conjunction with specific embodiments, describe the present invention in detail.
Embodiment
As shown in Figure 1, one end of housing arranges import, and the other end of housing arranges outlet ozzle, between housing and outlet ozzle, the adjustable packing ring of thickness is set; The inwall of housing arranges band chamfering step at entrance point, and spool and chamfering offset, and spool is horizontal U-shaped, and U-shaped spool inwall is provided with boss, between spool boss and the inwall of outlet ozzle, spring is set.
Housing and outlet ozzle material are aluminum alloy material; Spool is made up of polyimide plastic, and packing ring is fine aluminium packing ring, and spring is manufactured by Stainless Steel Wire.
Spool in closed condition, guarantees oppositely sealing under the effect of spring.When system is started working, gas flows into from entrance point, and inlet pressure raises, and when inlet gas active force is greater than after initial tension of spring, spool is opened, and gas is flow through smoothly.Spring rate is very little, and pretightening force is also very little, therefore opens pressure very low, can adjust the pretightening force of spring by changing gasket thickness, can guarantee working pressure≤0.2MPa, opens the requirement of pressure≤0.002MPa.After spool is opened, air-flow path is smooth and easy, and not larger turning round, does not have too small throttleng surface yet, can meet the requirement of flow resistance loss≤0.002MPa.When system quits work, or outlet end pressure raises suddenly, and spool can again be closed under spring and outlet pressure effect, prevents that the fluid of outlet end from flowing backwards.
Packing ring has array different-thickness to select, and can adjust the pretightening force of spring, guarantees the sealing between housing and outlet ozzle simultaneously.
The above is specific embodiments of the invention and the know-why used, and any equivalent transformation based on technical solution of the present invention basis, within all belonging to protection scope of the present invention.
