Abstract
The utility model relates to a part of a refrigeration compressor, in particular to a valve plate for a sealed refrigeration compressor cylinder, which is provided with a base plate; the base plate is provided with four screw holes at the four corners; the base plate is also provided with an air suction hole and an exhaust hole; the back of the base plate is provided with an exhaust valve piece groove shape; and the exhaust hole is arranged in the middle of the exhaust valve piece groove. The valve plate for the sealed refrigeration compressor cylinder is characterized in that the central lines of the exhaust hole and the air suction hole are positioned on the same central line of the valve plate; the air suction hole is in a rectangle shape, and the side of the rectangular air suction hole close to the front end is a long side which is in a camber line shape; and the four corners of the rectangular air suction hole are camber angles. Due to the structure, the valve plate for the sealed refrigeration compressor cylinder is beneficial to smooth exhausting, reducing of exhaust pressure loss, enlarging of the area of the air suction hole, reducing of the open loss of an air suction valve piece and improving of the air suction efficiency, thus being especially suitable for an air suction and exhaust system in a small-sized sealed refrigeration compressor.
Description
The (1) technical field: the utility model relates to the refrigeration compressor component, and especially a kind of sealed refrigeration compressor cylinder is used valve plate.
(2) background technique: at present; In refrigerator hermetically sealed compressor industry; Valve plate is as the closed end of compression cylinder; Have a suction port and exhaust port at least, major control flowing to of gas and is flowed out, and the suction port of valve plate and suction valve chip are formed Aspirating valves and controlled flowing to of air-flow; And the outflow of valve plate exhaust port and exhaust valve plate, exhaust buffer substrate tablet, exhaust limiting board composition outlet valve control gaseous, and the high efficiency of miniaturization sealed refrigeration compressor depends primarily on Aspirating valves and the good performance of outlet valve.Along with the continuous upgrading of country to energy consumption standard, if can promote the performance level of compressor through improvement Aspirating valves and outlet valve simultaneously, it is more and more important to seem.We know that the size that strengthens suction port can promote gettering efficiency, but traditional valve plate suction port generally is designed to circle; Referring to Fig. 1; Fig. 2, the round diameter design is excessive, and then corresponding suction valve chip seal section round diameter extends to the bent intermediate section; Cause that suction valve chip bending section length shortens, the corresponding increase of width, so just increased the unlatching moment of suction valve chip; On the other hand, the exhaust valve pool passage two side on the common valve plate is a straight line type, is unfavorable for the smoothness of exhaust.
The (3) summary of the invention: the purpose of the utility model will solve traditional valve plate exactly and adopt circular suction port; Aperture inconvenience design is excessive; The unlatching loss that influences suction valve chip increases; Influence problems such as raising and the exhaust passage fluency of gettering efficiency be not good, provide a kind of sealed refrigeration compressor cylinder to use valve plate.
The concrete scheme of the utility model is: improve to existing valve plate; It has substrate; Divide four jiaos on the substrate and have four screw holes, also have suction port and exhaust port on the substrate, have the outlet valve film trap at the back side of substrate; Exhaust port is positioned at the middle part of outlet valve film trap, it is characterized in that: said exhaust port center line and suction port center line are to be positioned on the same center line of valve plate; Said suction port is rectangle, and one side of the forward end of rectangular suction port is long limit, and this length limit is a camber line shape, and four jiaos of the rectangular suction port is arc round angle.
The vertical layout of center line of the long limit of the said suction port of the utility model and valve plate.
The utility model outlet valve film trap is an arc shaped surface near the side wall sections of exhaust port.
The utility model has the Aspirating valves film trap in the front of substrate, and said exhaust port and suction port all place in the Aspirating valves film trap.
The utility model is positioned at suction port on substrate the place ahead has mounting positioning groove.
The utlity model has following advantage:
1. the suction port profile changes rectangular into, can be designed to bigger hole area, reduces the cracking pressure loss, improves gettering efficiency;
2. be provided with the circular arc runner in the outlet valve film trap, be beneficial to the exhaust smoothness, reduce the exhaust pressure loss.

The (5) embodiment:
Example 1: referring to Fig. 3 .4, the utility model structure one is suitable for installing embedded suction valve chip; It has substrate 1; Divide four jiaos on the substrate 1 and have four screw holes 3, also have suction port 4 and exhaust port 2 on the substrate 1, have outlet valve film trap 5 at the back side of substrate 1; Exhaust port 2 is positioned at the middle part of outlet valve film trap 5; And have Aspirating valves film trap 7 in the front of substrate 1, said exhaust port 2 all places in the Aspirating valves film trap 7, particularly with suction port 4: said exhaust port 2 center lines and suction port 4 center lines are to be positioned on the same center line of valve plate; Said suction port 4 is rectangle, and one side of rectangular suction port 4 forward ends is long limit, and this length limit is a camber line shape, and four jiaos of rectangular suction port 4 is arc round angle.
The vertical layout of center line of the long limit of suction port described in the present embodiment 4 and valve plate.
The film trap 5 of outlet valve described in the present embodiment is an arc shaped surface 8 near the side wall sections of exhaust port 2.
The place ahead that on substrate 1, is positioned at suction port 4 in the present embodiment has mounting positioning groove 6.
Example 2: the utility model structure two has example 1 basic structure, and different is, Aspirating valves film trap 7 is not opened in the front of substrate 1 in the present embodiment, and referring to Fig. 5, this valve plate is fit to install the integrated type suction valve chip.
