Problems solved by technology

[0005] However, this method of overlapping the exhaust valve plate 3 and the stopper 4 and fixing them with fastening bolts 6, because there is no mutual restriction between the exhaust valve plate 3 and the stopper 4, it is easy to cause relative positional deviation. Offset, forming the situation shown in Figure 5, which will cause poor sealing of the exhaust valve plate 3 to the exhaust port 5 or the exhaust valve plate 3 will open when the compressed gas does not reach the specified pressure value, and these are abnormal Phenomena will seriously affect the normal operation of the compressor

Embodiment Construction

[0020] Referring to Fig. 6 and Fig. 7, the exhaust valve plate 3 and the limiter 4 are welded into one body by pressure welding, and there are three welding points 7, which are distributed in the through holes 8 of the exhaust valve plate 3 and the limiter 4 surrounding and distributed in a triangular shape. Pay attention to the vertical alignment of the exhaust valve plate 3 and the through hole 8 of the stopper 4 during welding.

Abstract

This invention relates to an integrated ventilation valve plate and a retainer system on a refrigeration rolled rotor compressor composed of a ventilation valve plate and a retainer to be connected to an integer by pressure solder, the jointing points of which are distributed in a triangle around the through hole of the valve plate and the retainer, in which no deviation will happen to each other since they are connected to an integer.

Description

1. Technical field [0001] The invention relates to a rolling rotor compressor system in a refrigeration device, in particular to a rolling rotor compressor system capable of avoiding relative movement of an exhaust valve plate and a limiter. 2. Background technology [0002] Generally speaking, the compressor is an important part of the refrigeration device, and together with the condenser, the expansion device and the evaporator, it forms a closed cycle system. In this cycle system, the compressor is responsible for compressing the low-temperature and low-pressure gaseous refrigerant sucked into the compressor, and discharging it in a high-temperature and high-pressure state, and the discharged gaseous refrigerant releases latent heat to the outside when passing through the condenser, thereby transformed into a liquid state. At the same time, the pressure is reduced when passing through the expansion device, and then the refrigerant in the low-pressure state is evaporated ...
