Description

The guiding one-way valve of quick-make

Technical field

The utility model relates to valve gate technology, particularly relates to a kind of technology of guiding one-way valve of quick-make.

Background technique

One-way valve is commonly used to various fluid piping system, for stoping the reverse flow of liquid or gas, to meet the specially designed performance requirement of product or equipment.

Conventional straight check valve, all utilizes the elastic elements such as spring valve block to be directly pressed on the sealed mouth place of valve body, when hydrodynamic pressure is greater than spring force, valve opening, fluid is passed through, when fluid reaction is in valve block, valve block under the double action of fluid and spring, in closed condition.Conventional straight check valve, structure is very simple, but its life-span is unreliable, and when opening, fluid pressure loss is larger.The guiding one-way valve of routine then also exists the slow shortcoming of closing velocity, and this can cause pent fluid to have the possibility of pressure release, and its reliability is also poor.

Model utility content

For the defect existed in above-mentioned prior art, it is fast that technical problem to be solved in the utility model is to provide a kind of closing velocity, the guiding one-way valve of the quick-make that reliability is high.

In order to solve the problems of the technologies described above, the guiding one-way valve of a kind of quick-make provided by the utility model, comprise valve body, valve body offers fluid inlet and fluid output, be formed with a stifled head piece in the inner chamber of valve body, and be provided with the valve plate that can cover the activity of this stifled head piece, when this stifled head piece is closed, fluid inlet on valve body and fluid output cut off mutually, and when this stifled head piece is open, the fluid inlet on valve body and fluid output are interconnected;

It is characterized in that: described valve body is built-in with the stage clip covering stifled head piece for ordering about valve plate, valve plate offering the capillary through holes in its plate face through, and when valve plate covers stifled head piece, capillary through holes and stifled head piece stagger mutually.

The guiding one-way valve of the quick-make that the utility model provides, the seal of fluid is making a concerted effort by means of the hydrodynamic pressure oppositely entered and stage clip, have the advantages that closing velocity is fast, and the hydrodynamic pressure oppositely entered is larger, then valve plate is also larger to the pressure of stifled head piece, and therefore the reliability of its sealing is also relatively high.

Embodiment

Illustrate below in conjunction with accompanying drawing and be described in further detail embodiment of the present utility model, but the present embodiment is not limited to the utility model, every employing analog structure of the present utility model and similar change thereof, all should list protection domain of the present utility model in.

As shown in Figure 1-Figure 3, the guiding one-way valve of a kind of quick-make that the utility model embodiment provides, comprise by valve body, described valve body is by valve casing 1, and the valve gap 2 be fixed on valve casing 1 forms, valve body offers fluid inlet 11 and fluid output 12, a stifled head piece 13 is formed in the inner chamber of valve body, and be provided with the valve plate that can cover the activity of this stifled head piece 13, described valve plate is combined by valve block 4 and compressing tablet 3, when this stifled head piece 13 is closed, fluid inlet 11 on valve body cuts off mutually with fluid output 12, when this stifled head piece 13 is open, fluid inlet 11 on valve body is interconnected with fluid output 12,

It is characterized in that: described valve body is built-in with the stage clip 5 covering stifled head piece 13 for ordering about valve plate, valve plate offering the capillary through holes 31 in its plate face through, and when valve plate covers stifled head piece 13, capillary through holes 31 and stifled head piece 13 stagger mutually.

The utility model embodiment is applicable to the water circuit system of the water treatment product of family expenses and similar applications, and its working principle is as follows:

When fluid forward enters, the hydrodynamic pressure of fluid inlet 11 side is greater than the hydrodynamic pressure of fluid output 12 side, if pressure difference is between the two greater than the elastic force of stage clip 5, then fluid meeting unseats valve plate, make stifled head piece 13 open, now one-way valve is in the forward conduction state shown in Fig. 1, and fluid also enters from fluid inlet 11 immediately, flows out after recrossing stifled head piece 13 from fluid output 12;

When fluid oppositely enters, the hydrodynamic pressure of fluid inlet 11 side is less than the hydrodynamic pressure of fluid output 12 side, now fluid can flow into valve plate dorsal part (dorsad stifled head piece 13 side) by capillary through holes 31, valve plate is under the elastic force of stage clip 5 and the force action of dorsal part hydrodynamic pressure, cover stifled head piece 13 fast, now one-way valve is in the closed condition shown in Fig. 2.
