Abstract
The utility model offers an anti-leak one-way valve, including a valve body 6, a valve body 10 and a valve seat 1. The valve is a plane plug 4 which can carry through an axial level movement by means of fluid pressure, the valve and the valve seat are sealed each other by a plane. The utility model has the advantages of: simple structure with a perfect sealing; without leaking and smooth operation; a good technology with a low cost. Thanks to the structure of the invention can be sealed once again; therefore the circumfluence can be effectively avoided farthest so as to ensure the purity of the fluid. The utility model can be applied widely in chemical engineering, pharmacy, environmental pollution, metallurgy, machine, daily life and other fields, in particular to be applicable for wastewater treatment and recycling of waste gas.
Description
Technical field
The utility model relates to the one-way valve technical field, specifically is a kind of anti-leak one-way valve.
Background technique
At present, existing one-way valve is the ball type one-way valve, and this kind valve is poor in processability not only, and exist sealing bad, easily produce problems such as fluid reflux, life-span be short, fragile when easily leaking and closing, usability is relatively poor, can not satisfy some use occasion, so its extensive use is restricted.
Summary of the invention
The purpose of this utility model provides a kind of anti-leak one-way valve, characteristics such as it has simple in structure, good airproof performance, does not leak, good manufacturability, cost is low, not fragile, the life-span is long.It can be the secondary seal structure, good seal, and effectively avoid refluxing.Can be widely used in chemical industry, pharmacy, environmental protection, metallurgy, machinery, field such as civilian, be particularly suitable in waste water, waste gas treatment and regeneration engineering, using.
Main technical schemes of the present utility model is: a kind of anti-leak one-way valve, comprise valve body, valve seat, valve, it is characterized in that valve be one can be under hydrodynamic pressure the axial plane plug of translation, valve and valve base chamber are the plane fitted seal.
It is good that above-mentioned plane is provided with sealing gasket beyond the Great Wall.
Above-mentioned can be under hydrodynamic pressure axially the structure of the plane of translation plug can be: the plane plug links to each other with guide rod, and guide rod is provided with Returnning spring, and valve body is provided with the Returnning spring rack of being with guide hole, and guide rod and guide hole are slidingly matched.
Above-mentioned can be under hydrodynamic pressure axially the plane of translation plug also can be cylindricality (circular or square etc.), valve body is provided with the cylindricality slideway that is slidingly matched with this plane plug, on this cylindricality slideway and valve body be provided with the water conservancy diversion duct.
Above-mentioned plane plug can link to each other with guide rod, and guide rod is provided with Returnning spring, and valve body is provided with the rack of Returnning spring.
Also can be provided with guide hole on the above-mentioned Returnning spring rack, guide rod and guide hole are slidingly matched.To increase the stability of guiding.
It is good that the outer cylinder of above-mentioned plane plug is provided with seal ring, and the sealing circle is in the fitting surface of valve and valve body and the position between the pod apertures when valve seals, to form secondary seal.
The cross-section area sum of above-mentioned pod apertures should be not less than the cross-section area of the minimum discharge orifice of valve seat.Do not subtract with dependable flow.
Above-mentioned plane plug is cylindrical to be good, and the described slideway that is slidingly matched with this plane plug is cylindrical slideway.More than the pod apertures 4 (containing 4), circumference uniform distribution is good.
Characteristics such as the utlity model has simple in structure, good airproof performance, do not leak, good manufacturability, cost are low when it is the secondary seal structure, can effectively be avoided refluxing to greatest extent, guarantee the degree of purity of fluid, and open steadily.Can be widely used in chemical industry, pharmacy, environmental protection, metallurgy, machinery, field such as civilian, be particularly suitable in waste water, waste gas treatment and regeneration engineering, using.
Be described further below in conjunction with embodiment, but not as to qualification of the present utility model.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among Fig. 1,1 is valve seat, and 2 is sealing gasket, and 3 is seal ring, and 4 are the plane plug, and 5 is water conservancy diversion duct (8 circumference uniform distributions), and 6 is valve body, and 7 is guide rod, and 8 is Returnning spring, and 9 are Returnning spring rack (guide hole is arranged or do not have guide hole), and 10 is valve body loose joint overcoat.
Embodiment
Referring to Fig. 1, when the right fluid during, promptly open plane plug 4 to certain pressure, make it the translation of turning left, when exposing the side mouth in water conservancy diversion duct 5, fluid can flow from right to left; When pressure little and the right pressure in the right is big, promptly stop to flow left.Valve plug available metal or engineering plastics cast moldings such as (cores).This product adopts secondary seal, guaranteeing to make outlet end become the aperture multichannel by single channel under the constant situation of effective drift diameter, has increased the backflow resistance and the return time of medium when closing.Abandoning the nature that varies in size of two ends lifting surface area when utilizing closed condition produces and promotes the thrust that valve plug (core) closes valve cuts out, the effect that Returnning spring arranged again just the spool action more fast, close more reliably, solved well that prior art is not closed completely and the difficult problem of turn-off transient medium back flow.
