Abstract
Description
Technical Field
[0001] This utility model relates to the field of compressor technology, and more specifically to a wide tongue reed compressor intake valve plate and compressor. Background Technology
[0002] The main components of a refrigerator compressor are the suction and discharge valves. Their operation involves opening and closing these valves to deliver refrigerant to the refrigeration system. When the compressor piston moves downwards, the pressure inside the cylinder decreases. The suction valve, under the pressure difference, overcomes the spring force and opens, allowing refrigerant gas to enter the cylinder from the evaporator through the suction pipe. The degree of valve opening automatically adjusts according to the suction pressure and flow rate to ensure an appropriate amount of refrigerant enters the cylinder.
[0003] As the piston moves upward, the refrigerant inside the cylinder is compressed, increasing its pressure. When the pressure reaches a certain level, the exhaust valve opens under the pressure difference, allowing refrigerant gas to exit the cylinder through the exhaust pipe and enter the condenser. The opening and closing of the exhaust valve must be adjusted promptly according to changes in exhaust pressure and flow rate to ensure smooth refrigerant discharge.
[0004] With the compressor and specifications unchanged, and the refrigeration passage remaining the same, in order to ensure compressor efficiency, the compressor's suction process can be made faster and more efficient by designing miniaturized suction valves. Furthermore, the area of the valve tongue spring is proportional to the mass flow rate. The larger the mass flow rate, the higher the compressor efficiency. The miniaturized valves are subjected to more complex stresses and strains during operation, which also places new demands on the valve structure and stability. Utility Model Content
[0005] The purpose of this invention is to provide a wide tongue reed compressor intake valve plate and compressor to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model employs the following technical means:
[0007] A wide-leaf compressor intake valve includes a valve body. A leaf spring, integrally formed with the valve body and corresponding to the intake port on the compressor, is disposed within the valve body. A gap is provided between the leaf spring and the valve body. The leaf spring includes an end, a cantilever, and a tail. The end is rectangular. The two ends of the cantilever gradually expand outward and connect to the end and tail respectively. The tail is an arc-shaped ring structure. Guide grooves that mate with the gap are provided on both sides of the end of the leaf spring. An oval-shaped ventilation groove is formed on the cantilever of the leaf spring.
[0008] Furthermore, the valve plate body has a rectangular structure, and the four corners of the valve plate body have an arc-shaped structure, with one of the corners having a positioning groove that is set in an arc.
[0009] Furthermore, mounting holes are provided at the four corners of the valve body, and a limiting groove is provided on the valve body located on one side of the tongue spring.
[0010] Furthermore, the tongue spring includes an end, a cantilever, and a tail. The connection between the two sides of the end and the valve plate body is a straight groove. The length of the end is 16.9 mm and the width of the end is 1.63 mm. The middle part of the cantilever is arc-shaped and its two ends gradually expand outward and connect to the end and the tail respectively. The outer arc radius of the tail is 11.0 mm.
[0011] Furthermore, the arc radii at both ends of the vent groove are 2.8mm and 4.5mm, respectively, and the smaller end of the vent groove is closer to the end of the tongue spring.
[0012] Furthermore, the width of the slit is 0.4 mm, and the width of the flow channel is 1.0 mm.
[0013] Secondly, this application provides a compressor, including: the wide tongue spring compressor suction valve plate described above.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] This invention, by setting the tongue spring to a wider tail and a smaller cantilever, can make the compressor's intake process faster and more efficient while ensuring a miniaturized intake valve plate. It can reduce intake resistance and increase intake volume. Furthermore, by setting guide slots on both sides of the tongue spring to fit the gap, the airflow can be further guided, thereby improving the overall performance and efficiency of the compressor. The energy loss of the compressor during operation will be reduced accordingly, thus reducing energy consumption. Attached Figure Description
