Description
Technical field
The utility model is related to valve fields, and in particular to a kind of single-lobe wafer type swing check valve.
Background technology
Swing check valve is also known as check valve or non-return valve, and effect is to prevent the medium in pipeline from flowing backwards, and swing type stops
It returns valve and is divided into three kinds of single-lobe formula, Double-disc type and multi-clove type, single-lobe formula swing check valve structure is relatively simple, but for mounting pin
Axis, valve body can be punched laterally, so that valve interior surface is penetrated through with outer surface, such structure makes the leakproofness of valve body can not
It leans on, therefore, it is necessary to make improvements.
The content of the invention
To solve the above-mentioned problems, the utility model provides a kind of single-lobe wafer type swing check valve.
The technical solution of the utility model is：A kind of single-lobe wafer type swing check valve, including valve body, flap, positioning
Block, axis pin, the section of valve body is circle, and the middle part of valve body is set passes through pin with valve body outer circle out-of-alignment circular channel, flap
Axis and locating piece are fixed on valve inner, and the section of flap is circle, and flap is arranged in circular channel to be led to for backstop fluid
It crosses, when flap is closed, the sealing surface of flap and the sealing surface of valve body fit.
Further, the flap is fixedly connected with locating piece, and locating piece rotates 180 degree around axis pin.
The beneficial effects of the utility model are：The utility model connection structure is simple, small, light-weight, service life
It is long, have a wide range of application.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the side view of the utility model.
Fig. 3 is the sealing surface of Fig. 1 flaps and the enlarged drawing when sealing surface of valve body fits.
Specific embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings, the present embodiment is not formed to this
The limitation of utility model.
A kind of single-lobe wafer type swing check valve, including valve body 1, circular channel 2, flap 3, axis pin 4, locating piece 5, close
Front cover 6.
As shown in Figure 1, 2, the section of valve body 1 is circle, and the middle part of valve body 1 is set and 1 outer circle out-of-alignment of valve body circle
Passage 2, flap 3 are fixed on by axis pin 4 and locating piece 5 inside valve body 1, and the section of flap 3 is circle, and flap 3 is arranged on circle
In shape passage 2 for backstop fluid by, as shown in figure 3, when flap 3 is closed, the sealing surface 6 of flap 3 and the sealing of valve body 1
Face fits.
Flap 3 is fixedly connected with locating piece 5, and locating piece 5 can rotate 180 degree around axis pin 4.
Operation principle is：As shown in Fig. 2, when medium flows to the right from left side, the pressure of medium is by flap around axis pin
Rotation, flap are opened counterclockwise, and medium passes through.When flap is closed, if having medium back flow, i.e., medium from right side to the left
Flowing, since locating piece can only be upward around axis pin, medium can not rotate clockwise flap around axis pin, and flap can not be opened, and be situated between
Matter cannot be by effective tissue mediators reflux.
The above descriptions are merely preferred embodiments of the present invention, is not used in limitation the utility model, this field skill
Art personnel can make the utility model various modifications or equivalent substitution in the essence and protection domain of the utility model,
This modification or equivalent substitution also should be regarded as in the protection domain of technical solutions of the utility model.
