Abstract
The one-way cut valve includes valve body and valve clack made of rubber and integrated with the valve body. Between the valve body and the valve clack, there is one cut. The valve body and the valve clack are set inside valve sleeve. The present invention utilizes cut as sealing surface and can seal completely. The valve body and the valve clack made of rubber have good self-restoring elasticity. During flowing in the forward direction, the fluid pressure overcomes the elasticity of the linking beam to open the valve clack for flow in the forward direction. After the fluid cuts off, the valve clack restores to close the valve body to arrest the reverse flow, resulting in no need of restoring spring. The present invention has the advantages of high sealing performance and no need of restoring spring.
Description
One, affiliated technical field
The present invention relates to a kind of one-way valve.
Two, background technique
At present, can only allow the one-way valve of fluid (gas or liquid) one-way flow, its structure is taked spherical flap or plane flap basically, and the add-back spring of moving is blocked the sealed mouth in the valve body.The one-way valve of this structure exists following defective: when making flap with Metal Ball or glass marble, the sphere precision be difficult to guarantee, the appearance of the phenomenon of leakage that causes leaking gas; Can't do without to add (resetting) spring that reverses, the elastic force conformity of backspring also is difficult to guarantee, especially hour at the pressure of the gas of one-way valve of flowing through (liquid) body, the elastic force difference of backspring just seems very outstanding, elastic force air flow slightly pushes up not open flap, the slightly little sealing of elastic force is bad, and reverse gas (liquid) body is taken advantage of a weak point, and pours in down a chimney and.
Three, summary of the invention
The objective of the invention is to overcome the above-mentioned defective that prior art exists, a kind of wound one-way valve is provided.
For finishing above-mentioned task, the solution that the present invention takes is: a kind of wound one-way valve, comprise valve body and flap, and integrated by flap and valve body that rubber is made, a wound is arranged between flap and the valve body, flap and valve body are placed in the valve pocket.
The present invention has changed the mentality of designing of present one-way valve fully, and it is promptly integrated that the flap that adopts rubber body and valve body directly are connected, and the sealing surface of flap and valve body is the wound of cutting open with scraper, so be referred to as the wound one-way valve.Cut the wound severed in other words open as sealing surface with scraper, its corresponding each point up and down fits like a glove.Because flap and valve body are integrated into by rubber, promptly their tie-beam also is a rubber material, self-healing good springiness.When the fluid following current, hydrodynamic pressure overcomes the elastic force of tie-beam, and flap is opened one-directional fluid flow.When cutout, flap automatically resets and promptly is close to valve body, stops retrograde fluid to be poured in down a chimney, and therefore just need not to be provided with backspring flap is resetted.The present invention kills two birds with one stone, and has promptly solved the sealing difficulty of sealing surface, has cancelled backspring again, does not have the inconsistent drawback of bringing of backspring elastic force.
Four, description of drawings
Fig. 1 is the sectional view of present embodiment.
Fig. 2 is the plan view of present embodiment.
Among the figure: 1, valve body, 2, flap, 3, valve pocket, A, wound, B, tie-beam.
Five, embodiment
Below in conjunction with embodiment and accompanying drawing thereof the present invention is remake description.
Referring to Fig. 1 and Fig. 2, a kind of wound one-way valve comprises valve body 1 and flap 2, and is integrated with valve body 1 by the flap 2 that rubber is made, and a wound A is arranged between flap 2 and the valve body 1, and flap 2 is placed in the valve pocket 3 with valve body 1.
Claims (1)
1, a kind of wound one-way valve, comprise valve body (1) and flap (2), it is characterized in that: integrated by the flap (2) that rubber is made with valve body (1), between flap (2) and the valve body (1) wound (A) is arranged, flap (2) is placed in the valve pocket (3) with valve body (1).
