Abstract

The utility model relates to a one-way valve for improving flow property. The one-way valve for improving flow property comprises a valve seat body, a pipe inlet pipe body and a pipe outlet pipe body are respectively arranged at the two ends of the valve seat body, a pipe inlet cavity inside the pipe inlet pipe body and a pipe outlet cavity inside the pipe outlet pipe body are respectively communicated with a working cavity inside the valve seat body, a barrier is arranged on the valve seat body at the bottom portion of the working cavity, the barrier divides the working cavity into a pipe inlet working cavity and a pipe outlet working cavity, the barrier divides the working cavity into the pipe inlet working cavity and the pipe outlet working cavity, cavity wall of the pipe inlet cavity and cavity wall of the pipe outlet cavity are respectively in smooth transition with lateral wall of the barrier through a curved surface, through the fact that the cavity wall of the pipe inlet cavity and the cavity wall of the pipe outlet cavity are respectively in smooth transition with the lateral wall of the barrier through a curved surface, when refrigerant fluid enters the valve seat, the refrigerant fluid can transit smoothly to the pipe inlet working cavity with the curved surface, and therefore impact to the barrier is reduced.

Description

Improve the one-way valve seat of trafficability performance

Technical field

The utility model relates to a kind of one-way valve seat that improves trafficability performance.

Background technique

Valve seat construction was simple in the past, but because inner defective of depositing in design, coolant is rear larger to the impact of the jube in the valve seat in entering into valve seat, easily with its damage.

The model utility content

The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of one-way valve seat that improves trafficability performance is provided, solve the in the past interior flimsy defective of jube of valve seat.

The technological scheme that its technical problem that solves the utility model adopts is: a kind of one-way valve seat that improves trafficability performance, has the valve seat body, described valve seat body two ends are respectively arranged with the inlet pipe body and go out body, the intrinsic active chamber of described valve seat communicates with inlet pipe chamber and the tube chamber that goes out that goes out in the body in the inlet pipe body respectively, described inlet pipe body is connected with respectively the connecting end body that is connected for pipeline with the mouth of pipe that goes out body, the external diameter of described connecting end body is less than inlet pipe body and the external diameter that goes out body, be provided with jube on the described valve seat body that is positioned at the active chamber inner bottom part, described jube is divided into active chamber the inlet pipe active chamber and goes out to manage active chamber, described jube is divided into active chamber the inlet pipe active chamber and goes out to manage active chamber, the sidewall of described jube respectively and an inlet pipe chamber chamber ancient piece of jade, round, flat and with a hole in its centre and going out between the ancient piece of jade, round, flat and with a hole in its centre of tube chamber chamber seamlessly transit by curved surface.

The beneficial effects of the utility model are: the sidewall by jube respectively and an inlet pipe chamber chamber ancient piece of jade, round, flat and with a hole in its centre and going out between the ancient piece of jade, round, flat and with a hole in its centre of tube chamber chamber seamlessly transit by curved surface, the coolant that is is after entering valve seat, coolant can be smoothly transitted into the inlet pipe active chamber along with curved surface, reduces the impact to jube.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 be valve seat partly cut open structural representation;

Wherein: 1, valve seat body, 2, the inlet pipe body, 3, go out body, 4, jube.

Embodiment

By reference to the accompanying drawings the utility model is further described now.The schematic representation that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.

A kind of one-way valve seat that improves trafficability performance as shown in Figure 1, has valve seat body 1, valve seat body 1 two ends are respectively arranged with inlet pipe body 2 and go out body 3, active chamber in the valve seat body 1 respectively with inlet pipe body 2 in the inlet pipe chamber and the tube chamber that goes out that goes out in the body 3 communicate, inlet pipe body 2 is connected with respectively the connecting end body that is connected for pipeline with the mouth of pipe that goes out body 3, the external diameter of connecting end body is less than inlet pipe body 2 and the external diameter that goes out body 3, be positioned on the valve seat body 1 of active chamber inner bottom part and be provided with jube 4, jube 4 is divided into active chamber the inlet pipe active chamber and goes out to manage active chamber, jube 4 is divided into active chamber the inlet pipe active chamber and goes out to manage active chamber, the sidewall of jube 4 respectively and an inlet pipe chamber chamber ancient piece of jade, round, flat and with a hole in its centre and going out between the ancient piece of jade, round, flat and with a hole in its centre of tube chamber chamber seamlessly transit by curved surface.

Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this model utility technological thought, carry out various change and modification fully.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
