Abstract
The utility model discloses a one-way valve of a displacement pump to solve the problem that high-temperature media can not be transmitted through an existing ordinary displacement pump, and relates to the field of displacement pumps. The one-way valve of the displacement pump comprises a valve body, wherein an inlet one-way valve main body and an outlet one-way valve main body are arranged on the valve body, a bypass opening is formed between the inlet one-way valve main body and the outlet one-way valve main body, and the bypass opening is connected with a pump body of the displacement pump through a water inlet and outlet pipe. When the pump body does the suction stroke movement, water comes in through the inlet one-way valve main body, the media enter the water inlet and outlet pipe, and at the moment, the outlet one-way valve main body is in the closed state. Before the media in the water inlet and outlet pipe flow into the pump body, the pump body does the extending stroke movement, the inlet one-way valve main body is closed to play a role in stopping returning, the media are pushed to flow out of the outlet one-way valve main body, and then oriented transmission of the media is achieved. In the process, the media only pass through the valve body of the one-way valve and the water inlet and outlet pipe and can not make contact with a membrane of a membrane pump or a piston of a plunger pump, the temperature of the media can not be transferred into the pump body, and the aim of transmitting the high-temperature media through the pump body made of the ordinary materials is achieved.

The beneficial effects of the utility model:
The one-way valve of displacement pump in the utility model, import one-way valve and outlet one-way valve are made of one to structure, and the turnover water pipe that connects the pump housing is set, can avoid high temperature media to pass through positive-displacement pump itself, thereby avoid the moving element of the pump housing to be damaged by high temperature media, realize the displacement pump of normal temperature design and can normally carry high temperature media yet, improved displacement pump reliability of operation, flow does not change with medium temperature.
These features of the present utility model and advantage will be below embodiment, accompanying drawing in detailed exposure.
[accompanying drawing explanation]
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is structural representation of the present utility model.
[embodiment]
The utility model provides a kind of one-way valve of displacement pump, comprises valve body, and valve body is provided with import one-way valve and outlet one-way valve, between import one-way valve and outlet one-way valve, is provided with by-pass port, and by-pass port connects the pump housing of displacement pump by turnover water pipe.
When the pump housing is suction Cheng Yundong, the water inlet of import one-way valve, medium flows into turnover water pipe, export one-way valve in closed condition, the medium in turnover water pipe does not flow into before the pump housing this moment, and the pump housing is done rise motion, import closed check valve plays non-return effect, and medium is pushed from outlet one-way valve and flows out.Thereby the orientation that realizes medium is carried, and in the middle of this process, medium only can pass through valve body and the turnover water pipe of one-way valve, can't be with the diaphragm of diaphragm pump or the contact of the piston of piston pump, the temperature of medium can not imported pump body into, thereby realizes the object that the common material pump housing is carried high temperature media.
Accompanying drawing below in conjunction with the utility model embodiment is explained and illustrated the utility model embodiment's technological scheme, but following embodiment is only preferred embodiment of the present utility model, not all.Embodiment based in mode of execution, those skilled in the art are other embodiment that obtains under the prerequisite of not making creative work, all belongs to protection domain of the present utility model.
With reference to figure 1, the one-way valve of shown displacement pump, comprises valve body 1, and valve body 1 is provided with import one-way valve and outlet one-way valve, between import one-way valve and outlet one-way valve, is provided with by-pass port 14, and by-pass port 14 connects the pump housing of displacement pump by turnover water pipe 4.When the pump housing is inhaled journey action, the water inlet of import one-way valve, medium flows into turnover water pipe, and before medium does not flow into the pump housing, the pump housing is done rise motion, and medium is pushed from outlet one-way valve and flows out.
Wherein valve body 1 comprises intake tunnel 11, exhalant canal 13 and the connecting passage 12 that is communicated with intake tunnel 11 and exhalant canal 13, by-pass port 14 is set on connecting passage 12, at intake tunnel 11 and connecting passage 12 intersections, import one-way valve is set, at exhalant canal 13 and connecting passage 12 intersections, outlet one-way valve is set, valve body is set for this structure, import one-way valve and outlet one-way valve can be arranged on same valve body 1 simultaneously, the structure of valve body integral body is little, and consumptive material is few.
