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

Integrated type vent valve piece and position limitator

One, technical field

The present invention relates to the compressor with rolling rotor system in the refrigeration plant, relate in particular to a kind of compressor with rolling rotor system that can avoid exhaust valve plate and snubber to relatively move.

Two, background technique

In general, compressor is the vitals in the refrigeration plant, and it constitutes the circulatory system of sealing with condenser, expansion gear, vaporizer.In this circulatory system, the gaseous refrigerant that compressor is responsible for being drawn into the low-temp low-pressure state in the compressor compresses, discharge with high-temperature high-pressure state, and the gaseous refrigerant of discharging discharges latent heat to the outside by condenser the time, thus the liquid state of being converted into.Simultaneously, by expansion gear the time, reduce pressure, and then, evaporate the refrigeration agent of low-pressure state, thereby absorb outside heat by in the process of vaporizer.Vaporized refrigeration agent then flow in the compressor again.The circulatory system realizes freezing by carrying out said process repeatedly.

And in this course, the effect of compressor is to pressurizes refrigerant, makes the pressure of refrigeration agent and the requirement that temperature reaches regulation, for this reason, is provided with exhaust valve plate and snubber in the compressor, can both meet the requirements prescribed to guarantee the gas of discharging from compressor.Its concrete structure is as follows.

With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, the main shaft 2 of compressor with rolling rotor is installed on the upper bearing 1, exhaust valve plate 3 covers on relief opening 5, and snubber 4 is pressed on the

exhaust valve plate

3, and 6 of clamping bolts are fixed on exhaust valve plate 3 and snubber 4 on the upper bearing 1 together.When the pressurized gas of compressor with rolling rotor inside reaches the force value of regulation, exhaust valve plate 3 will be opened automatically, and pressurized gas is discharged from relief opening 5, and the effect of snubber 4 then is to prevent that exhaust valve plate 3 from excessively opening, so that it is shielded.

Yet, this exhaust valve plate 3 and snubber 4 are overlaped with the fixing method of clamping bolt 6, owing to do not have mutual restriction between exhaust valve plate 3 and the snubber 4, be easy to cause the skew of relative position, form situation as shown in Figure 5, thereby exhaust valve plate 3 is opened in the time of can causing the poor sealing of 3 pairs of relief openings 5 of exhaust valve plate or force value that pressurized gas does not reach regulation, and these abnormalities all will have a strong impact on the proper functioning of compressor.

Three, summary of the invention

Purpose of the present invention promptly is the deficiency at above-mentioned prior art, and exhaust valve plate and snubber are adopted a kind of new connecting means, makes its skew that can not cause relative position each other, thereby compressor is worked under normal state all the time.

The objective of the invention is to realize by following technological scheme.

A kind of integrated type vent valve piece and position limitator that is installed on the cooling compressor with rolling rotor is made up of exhaust valve plate 3 and snubber 4, it is characterized in that described exhaust valve plate 3 and described snubber 4 usefulness pressure weldings link into an integrated entity.

Purpose of the present invention can also further realize by the following technical programs.

Aforesaid integrated type vent valve piece and the position limitator that is installed on the cooling compressor with rolling rotor is characterized in that its soldering point 7 of described pressure welding is positioned at through hole 8 peripheries of exhaust valve plate 3 and snubber 4.

Aforesaid integrated type vent valve piece and the position limitator that is installed on the cooling compressor with rolling rotor is characterized in that the soldering point 7 of described pressure welding is three, and distribution triangular in shape.

The integrated type vent valve piece and the position limitator that adopt the technology of the present invention to make, after being installed on the compressor with rolling rotor, when the compressor with rolling rotor gas inside reaches the force value of regulation, exhaust valve plate 3 will be opened automatically, and pressurized gas is discharged from relief opening 5.Because the method for exhaust valve plate 3 and snubber 4 usefulness pressure weldings has been welded into one securely, its relative position can not be offset, therefore stopped to take place between mutually the poor sealing and the exhaust valve plate 3 of 3 pairs of relief openings 5 of exhaust valve plate that skew causes and when pressurized gas does not reach the force value of regulation, opened the generation of phenomenon, thereby compressor is always worked under the normal state because of exhaust valve plate 3 and snubber 4.

Five, embodiment

With reference to Fig. 6, Fig. 7, exhaust valve plate 3 and snubber 4 adopt the integrally welded formula of method of pressure welding, and soldering point 7 is three, is distributed in through hole 8 peripheries of exhaust valve plate 3 and snubber 4, and distribution triangular in shape.Should note through hole 8 consistencies from top to bottom of exhaust valve plate 3 and snubber 4 during welding.
