Abstract
The utility model discloses a kind of Novel check valve piece, including circular valve block body, sealing gasket and sealing ring, sealing ring is arranged on the circular valve block body, sealing ring is arranged on sealing gasket, it is provided with circular valve block body on turtleback shape projection and hook-type connector, hook-type connector and is provided with bolt hole.Circular valve block body of the present utility model has anti-deformation in long-term opening, closing process, and durable characteristic can be closed rapidly while the utility model also has after self-priming pump drainage, and can hold sealing very well, prevents liquid backflow.
Description
Technical field
The utility model belongs to pump valve technical field, more particularly to a kind of Novel check valve piece.
Background technology
The principle that self priming pump can work be before pump startup in contain after enough self-priming drainage-fluids, pump startup, due to
Impeller turning effort, is discharged gas by gas-liquid mixed, gas-liquid separation, so as to realize self-priming.After pump is shut down, due to inlet tube
Interior is negative pressure, and exports that overpressure is higher, and the liquid in inlet ductwork and the pump housing is back to liquid storage tank, until in inlet ductwork
Negative pressure disappear, although the liquid in the pump housing will not be missed all, but liquid level in the pump housing declines, and causes the amount of liquid storage in the pump housing
It is very few, then when starting shooting, pump can not realize self-priming, it is impossible to the performance requirement of self priming pump " drainage, lifelong self-priming " is realized, this is just
It is required that the check valve sheet sealing in self priming pump is very tight, and existing check valve sheet is often poorly sealed, while existing list
Check valve sheet deformation is easily caused when such reciprocating action is constantly opened and closed to valve block, check valve sheet is reduced
Service life so that check valve sheet is not tight with valve base sealing, causes self priming pump hydraulic performance decline or failure.
Utility model content
The purpose of this utility model is the Novel check valve piece for providing a kind of good seal performance, service life length, to solve
The problem of being proposed in certainly above-mentioned background technology.
To achieve these goals, the utility model employs following technical scheme：
A kind of Novel check valve piece, including circular valve block body, sealing gasket and sealing ring, the sealing ring are arranged on described
On circular valve block body, the sealing ring is arranged on sealing gasket, be provided with the circular valve block body turtleback shape it is raised and
Bolt hole is provided with hook-type connector, the hook-type connector.
In order to further optimize above-mentioned technical proposal, the technical measures that the utility model is used also include：
It is preferred that, the circular valve block body, sealing gasket and sealing ring are formed in one.
It is preferred that, the sealing ring and sealing gasket are prepared by quality of rubber materials.
It is preferred that, the circular valve block body carries chuck layer, and the circular valve block body is prepared by stainless steel material.
Compared with prior art, a kind of Novel check valve piece that the utility model is provided, its advantage is：
Turtleback shape is provided with circular valve block body in the utility model raised, circular this physical efficiency of valve block bears bigger
Pressure, it is prolonged do not allow when opening and closing such reciprocating action it is fragile, with anti-deformation, durable characteristic.Sealing
Circle and sealing gasket coordinate, and can be closed rapidly after check valve sheet draining, and can hold sealing very well, prevent liquid backflow, sealing
Can be good.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation that the utility model is arranged in self priming pump；
Reference therein is：100-circle valve block body；101-turtleback shape is raised；102-hook-type connector,
103-bolt hole；200-sealing gasket；300-sealing ring.
Embodiment
The technical solution of the utility model is further explained below in conjunction with drawings and examples, but below interior
Appearance is not used in restriction protection domain of the present utility model.
Shown in reference picture 1, the present embodiment provides a kind of Novel check valve piece, including circular valve block body 100, sealing gasket
200 and sealing ring 300, sealing ring 300 is arranged on circular valve block body 100, and sealing ring 300 is arranged on sealing gasket 200, circle
It is provided with shape valve block body 100 on turtleback shape projection 201 and hook-type connector 102, hook-type connector 102 and is provided with bolt hole
103。
Operation principle of the present utility model is：Coordinate in the utility model corresponding bolt hole 103 by check valve with bolt
Piece is fixed in the water storage cavity room of self priming pump, self priming pump start, and now water storage chamber air is discharged, and forms negative in chamber
Pressure, negative pressure makes circular valve block body 100 be in open mode, realizes water absorption course.The current of delivery port are returned after self priming pump is shut down
Flow in water storage cavity room, hydraulic pressure closes circular valve block body 100, as shown in Fig. 2 the now sealing of circular valve block body 100
By water storage cavity seal in corresponding valve seat pipeline on the insertion self priming pump of circle 300, while sealing gasket 200 is close to corresponding valve seat
Pipeline opening realizes further sealing, and turtleback shape projection 101 adds the hydraulic pressure area of circular valve block body 100, water pressure energy
Circular valve block body 100 is more effectively compressed, the rigid of circular valve block body 100 is also increased, is opening for a long time
Do not allow with circular valve block body 100 when closing such reciprocating action yielding.
As a preferred embodiment, circular valve block body 100, sealing gasket 200 and sealing ring 300 are formed in one,
Integrally formed structural strength is bigger, and service life is longer.
As a preferred embodiment, sealing ring 300 and sealing gasket 200 are prepared by quality of rubber materials, and quality of rubber materials is not
But light weight and with fine sealing property.
As a preferred embodiment, the circular valve block body 100 carries chuck layer, the circular valve block body
100 are prepared by stainless steel material, mitigate the weight of circular valve block body 100, while can obtain more preferable compressive resistance again.
It is not new to this practicality although above-mentioned embodiment of the present utility model is described with reference to accompanying drawing
The limitation of type protection domain, one of ordinary skill in the art should be understood that on the basis of the technical solution of the utility model, ability
Field technique personnel need not pay the various modifications that creative work can make or deform still in protection model of the present utility model
In enclosing.
