Radiating fin.
Beneficial effects of the present invention:
The check valve of displacement pump in the present invention, is made of one structure by import check valve and Outlet check valves, and
And the water inlet pipe and water outlet pipe connecting the pump housing is set, it is avoided that high-temperature medium passes through positive-displacement pump itself, thus avoids
The moving component of the pump housing is damaged by high-temperature medium, it is achieved the displacement pump of room temperature design also can normally carry high temperature and be situated between
Matter, improves displacement pump reliability of operation, and flow does not changes with medium temperature change.
These features of the present invention and advantage will be detailed in following detailed description of the invention, accompanying drawing exposure.
[accompanying drawing explanation]
The present invention is described further below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of the present invention.
[detailed description of the invention]
The present invention provides the check valve of a kind of displacement pump, and including valve body, valve body is provided with import check valve and goes out
Mouth check valve, is provided with by-pass port between import check valve and Outlet check valves, by-pass port is by water inlet pipe and water outlet pipe even
Connect the pump housing of displacement pump.
When the pump housing does suction motion, import check valve is intake, and medium flows into water inlet pipe and water outlet pipe, exports list this moment
Being closed to valve, before the medium in water inlet pipe and water outlet pipe does not flows into the pump housing, the pump housing does rise motion, import
Closed check valve plays non-return effect, and medium is promoted to flow out from Outlet check valves.Thus realize the orientation of medium
Conveying, and in the middle of this process, medium only can by the valve body of check valve and water inlet pipe and water outlet pipe, can't follow every
The diaphragm of membrane pump or the piston contact of piston pump, the temperature of medium will not incoming pump body, thus realize
The purpose of common material pump housing conveying high-temperature medium.
The technical scheme of the embodiment of the present invention is explained and says by the accompanying drawing below in conjunction with the embodiment of the present invention
Bright, but following embodiment is only the preferred embodiments of the present invention, and not all.Based in embodiment
Embodiment, those skilled in the art are obtained other embodiments on the premise of not making creative work,
Broadly fall into protection scope of the present invention.
With reference to Fig. 1, the check valve of shown displacement pump, including valve body 1, valve body 1 is provided with import check valve
And Outlet check valves, be provided with by-pass port 14 between import check valve and Outlet check valves, by-pass port 14 pass through into
Outlet pipe 4 connects the pump housing of displacement pump.During pump housing suction action, import check valve intake, medium flow into into
Outlet pipe, before medium does not flows into the pump housing, the pump housing does rise motion, and medium is promoted from Outlet check valves stream
Go out.
Wherein valve body 1 includes that intake tunnel 11, exhalant canal 13 and connection intake tunnel 11 and water outlet are led to
The interface channel 12 in road 13, interface channel 12 arranges by-pass port 14, logical at intake tunnel 11 and connection
Road 12 intersection arranges import check valve, arranges outlet at exhalant canal 13 and interface channel 12 intersection single
To valve, arranging valve body is this structure, and import check valve and Outlet check valves can be simultaneously located at same valve body 1
On, the structure of valve body entirety is little, and consumptive material is few.
