Abstract
The invention discloses a one-way valve of a displacement pump, and relates to the field of displacement pumps. The one-way valve resolves the technical problem that an existing common displacement pump cannot convey high-temperature media. The one-way valve of the displacement pump comprises a valve body, wherein the valve body is provided with an inlet one-way valve and an outlet one-way valve, a bypass opening is formed between the inlet one-way valve and the outlet one-way valve, and the bypass opening is connected with a pump body of the displacement pump through a water inlet-outlet pipe. When the pump body carries out suction stroke movement, water enters the inlet one-way valve, at the moment, the outlet one-way valve is in a closed state, the pump body carries out pushing stroke movement before media in the water inlet-outlet pipe do not flow into the pump body, the inlet one-way valve is closed to play a role in stopping, the media are pushed to flow out of the outlet one-way valve, and directional conveying 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-outlet pipe and cannot make contact with a membrane of a membrane pump or a piston of a plunger pump, the temperature of the media cannot be transmitted into the pump body, and the purpose that the high-temperature media are conveyed through the pump body made of common materials is realized.

Beneficial effect of the present invention:
The one-way valve of displacement pump in the present invention, 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 invention and advantage will be below embodiment, accompanying drawing in detailed exposure.
[accompanying drawing explanation]
Below in conjunction with accompanying drawing, the present invention is described further:
Fig. 1 is structural representation of the present invention.
[embodiment]
The one-way valve that the invention provides a kind 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 embodiment of the present invention is explained and illustrated the technological scheme of the embodiment of the present invention, but following embodiment is only the preferred embodiments of the present invention, 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 scope of the present invention.
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.
Preferably, import one-way valve and outlet one-way valve include dividing plate, the dividing plate 31 of import one-way valve intercepts intake tunnel 11 and connecting passage 12, the dividing plate 41 of outlet one-way valve intercepts exhalant canal 13 and connecting passage 12, between the inwall of the dividing plate 31 of import one-way valve and relative connecting passage 12, being provided with the first elastic component 32, the first elastic components 32 is arranged on the mounting hole of valve body by the first nut 33; Between the dividing plate 41 of outlet one-way valve and the inwall of relative exhalant canal 13, being provided with the second elastic component 42, the second elastic components 42 is arranged on another mounting hole of valve body by the second nut 43.Compare the one-way valve that adopts other structures, this more compact structure, dismounting and easy for installation, and low to the size requirement of valve body, two one-way valves just can be installed in less valve body.Wherein the first elastic component and the second elastic component are stage clip.
In turnover water pipe 4 of the present invention, be provided with the damp block 41 of anti-whirlpool, and damp block 41 is arranged on one end that turnover water pipe 4 is connected with by-pass port 14, damp block 41 is along the radially setting of turnover water pipe 4, the stopping of damp block prevents from forming whirlpool in turnover water pipe and affected the flow of turnover water pipe, the capacity that guarantees turnover water pipe, under enough capacity, fluid can not flow into the pump housing.
Preferred damp block 41 is spider, the Si Ge angle of spider is connected with the inwall of turnover water pipe, and spider is separated into 4 through holes by the inner chamber of turnover water pipe, during the rotation of current eddy current, by spider, stopped destruction, effective guarantee current are along the axial flow of turnover water pipe.
In addition; turnover water pipe connects pump housing one end and is socketed with radiator; radiator is provided with radiating fin; in turnover water pipe delivering hot water process, the temperature of turnover water pipe is high, and heat is heat conducting by turnover water pipe time; by radiator, can distribute the temperature that turnover water pipe passes to the pump housing; alleviate being heated of the pump housing, further protect the moving element of displacement pump, improve the working life of diaphragm of diaphragm pump or plunger pump piston.
By above-described embodiment, object of the present invention is by fully effective having reached.The personage who is familiar with this technology should be understood that the content that the present invention includes but be not limited to accompanying drawing and describe in embodiment above.Any modification that does not depart from function and structure principle of the present invention all will be included in the scope of claims.
