The valve plate for the freezer compressor is capable of increasing a suction volume of a refrigerating agent, reducing pressure loss of a fluid during flowing, and thus increasing a refrigerating volume and a coefficient of performance (COP) of the compressor.
Description
Technical field
The utility model relates to a kind of valve plate that is applicable to freezer compressor, the valve plate that specifically a kind of air-breathing valve port cross-sectional passage is curve shape.
Background technique
At present, how to produce efficient, energy-conservation, compressor is the focus that producer pays close attention to cheaply, the key of Ye Shi compressor manufacturer existence.Valve group is the heart of compressor, and the performance of valve group directly affects the performance parameter such as refrigerating capacity, COP of compressor.Valve plate is the important component part of valve group, in compressor operating process with suction and the outflow of suction valve chip, exhaust valve plate co-controlling refrigeration agent.As depicted in figs. 1 and 2, the air-breathing valve port of existing valve plate is usually designed to circle or kidney-shaped, and two ends are with certain chamfering or cambered surface, and the body shape of valve port cross-sectional passage is generally straight line.Because the diameter of the air intake passage of valve plate is generally all smaller, pressure reduces to the air outlet of valve plate gradually from the suction port of valve plate, thereby can not improve the refrigeration agent intake of compressor.Meanwhile, the straight line type passage of existing valve port can cause the larger pressure loss, thereby has further reduced intake and the efficiency of refrigeration agent.
Summary of the invention
Technical problem to be solved in the utility model is to propose a kind of intake that improves refrigeration agent, reduces the pressure loss of fluid in the time flowing, thereby promotes the refrigerating capacity of compressor and the valve plate for freezer compressor of COP.
For solving the problems of the technologies described above, a kind of valve plate for freezer compressor of the utility model comprises valve plate body, and described valve plate body is provided with suction port, and the passage of described suction port is provided with throat, and the edge, cross section of the passage of described suction port is shaped as curve-like.
Above-mentioned a kind of valve plate for freezer compressor, the diameter of the passage of described suction port dwindles to described throat gradually from suction port, increases gradually to air outlet from described throat.
Above-mentioned a kind of valve plate for freezer compressor, described throat is 0.4～0.6 apart from the height of intakeport end face of passage and the ratio of the whole height of described valve plate body of described suction port, thereby the setting that makes throat position can ensure that fluid, through fully development before throat, can ensure again still have enough passage diverging flows through fluid after throat.
Above-mentioned a kind of valve plate for freezer compressor, the curve shape at the edge, cross section of described suction port passage is the streamline when approaching fluid and flowing through valve port.
Above-mentioned a kind of valve plate for freezer compressor, the curve shape at the edge, cross section of described suction port passage is parabola or spline curve.
Above-mentioned a kind of valve plate for freezer compressor, the rear and front end of edge, the cross section curve of described suction port passage adds respectively chamfering or rounding.
Above-mentioned a kind of valve plate for freezer compressor, described valve plate body adopts PEEK engineering plastics to process.
The utility model is owing to having adopted above-mentioned technical pattern, it utilizes the laryngeal structure of suction port passage and the curve shape at edge, cross section, between throat and air outlet, form low pressure area, therefore larger pressure difference can be between suction port and throat, formed, thereby the intake of refrigeration agent can be significantly promoted.The edge, cross section of suction port passage adopts curve shape also to reduce pressure loss when fluid flows through passage simultaneously, thereby has improved refrigerating capacity and the Energy Efficiency Ratio of compressor.

Embodiment
As shown in Figure 3, a kind of valve plate for freezer compressor of the utility model comprises valve plate body 1, and valve plate body 1 is provided with suction port 3.
As shown in Figure 4, the edge, cross section of the passage 2 of suction port 3 is shaped as curve-like.There is respectively chamfer machining at the suction port 6 of passage 2 and 4 places, air outlet (being the rear and front end of curve).The passage of suction port 3 is provided with throat 5, and the aperture of the passage 2 of suction port 3 dwindles to throat 5 gradually from intakeport 6, increases gradually to air outlet 4 from throat 5, and the hydrodynamic pressure of throat 5 is lower than the hydrodynamic pressure at intakeport 6 places.Like this, increase the pressure difference of fluid between throat 5 and intakeport 6 by the structure that adopts throat 5, increased the difference of P1 and P2, therefore can increase the fluid mass flow by air-breathing valve port.Meanwhile, compared with rectilinear form, when edge, the cross section curve of the passage 2 of suction port 3 more approaches fluid and flows through valve port streamline, therefore can reduce significantly fluid and flow through the pressure loss of valve port passage.
As a kind of preferred version, throat can select apart from the ratio of the height of the intakeport end face of the passage of suction port and the whole height of valve plate body between 0.4～0.6, like this, can ensure fluid fully development before process throat, can ensure again still there is enough passage diverging flows through fluid after throat, thereby make the impact that can weigh well this two aspects factor that arranges of throat position.
Because the utility model has adopted the suction port passage 2 of above-mentioned shape, the engineering plastics that valve plate body 1 can adopt PEEK etc. can meet compressor operating environment process, so both overcame the manufacturing process difficulty in enormous quantities that adopts at present conventional powder metallurgy and machining to bring, easily processing, and cost-saved, met again temperature variation that under compressor internal environment, needs stand and chemistry and the physical environment of refrigeration agent simultaneously.Certainly, the utility model valve plate body still can adopt the metallic material such as powder metallurgy to make.
Compared with prior art, the utility model has following apparent outstanding substantive distinguishing features and remarkable advantage: one, the suction port of valve plate adopts laryngeal structure, has effectively increased the mass flow rate of fluid, has promoted refrigerating capacity.Two, the suction port of valve plate adopts the curve that approaches fluid flow line, has reduced fluid by the pressure loss of valve port passage, promotes the efficiency of compressor.
In the utility model structure, edge, the cross section shape of the passage of suction port is not limited by above-mentioned mode of execution, can change.The curve of edge, the cross section shape of suction port passage can be the pattern such as parabola or spline curve, streamline when shape will approach fluid and flows through valve port.Equally, the shape of intakeport also can be done to change, and also can adopt arc machining at suction port or the air outlet place of the passage of intakeport.Edge, the cross section shape of suction port passage can be the curve without chamfering or rounding, also can add chamfering or rounding in the rear and front end of curve.
