Abstract
The utility model relates to a by-pass automatic pressure regulating valve, comprising a valve body, a sleeve barrel, a regulating nut, a regulating spring, a spring seat, a steel ball, etc. The steel ball is connected with a ripple pipe which is provided with assemblies of a driving rod, etc. The driving rod is connected with the spring seat. The by-pass automatic pressure regulating valve is suitable for various separate and stand cabinet type air conditioners with hot pump types to be used as the protecting device of a compressor. The by-pass automatic pressure regulating valve has the features of small size, light weight, convenient installation, high sensitivity, less leakage amount, etc.
Description
The utility model relates to pressure regulator valve, is applicable to that heat pump type is split type, in the vertical air conditioner machine, as the release of pressure protective gear of compressor.
All kinds of heat pump types are split type, the vertical air conditioner machine; general between the high and low pressure balance safety by-pass road of compressor; the automatic pressure modulating valve is installed; when high-pressure surpassed a certain setting, this valve can be opened automatically, and part of refrigerant is then passed through valve by-pass port system to the low pressure current drainage; thereby protected compressor; make compressor avoid overlond running, prolonged the life-span, and guarantee the proper functioning of system.Existing this class by-pass and pressure regulator valve, the diaphragm of ining succession on the steel ball in its valve body relies on the elasticity of this diaphragm that valve is played the fine setting effect.Therefore, there is following defective in this valve: the one, and diaphragm area is bigger, thus the valve body that need expand makes the whole valve volume heaviness that seems; The 2nd, poor sensitivity is subjected to the influence of diaphragm material because of sensitivity; The 3rd, leakage rate is big, environmental pollution; Four are to use the life-span short.
The purpose of this utility model is that design a kind ofly changes the diaphragm type in the valve body into bellow type, thereby overcomes the bypass automatic pressure modulating valve of above-mentioned defective.
The technological scheme of the utility model bypass automatic pressure modulating valve is: be made up of institutes such as valve body, adjusting nut, Regulation spring, spring seat and steel balls, connect bellows on its steel ball, drive link is arranged in the bellows, drive link connects spring seat.
The utility model bypass automatic pressure modulating valve is installed drive block between bellows and drive link, drive block is contacted with bellows, and not only stable drive is avoided Bellow Expansion Joint Failure again.
Bypass automatic pressure modulating valve of the present utility model has contiguous block in the bellows, bellows links to each other with setting sleeve again with contiguous block, and connects with steel ball, can be connected firmly like this by methods such as welding, and motion steadily.
Bypass automatic pressure modulating valve of the present utility model, the top of its valve body are continuous sleeves such as screw thread, and spring seat has positioning seat outward.Operation is convenient to make, is installed and be beneficial to this structure.
The utility model discloses a kind of bypass automatic pressure modulating valve, mainly replace the diaphragm type of prior art with structures such as bellowss, following good effect is arranged: volume is little, in light weight, easy for installation, the serviceability temperature scope is wide, highly sensitive, leakage rate reduces by 4 times, and the life-span can be doubled and redoubled.
Fig. 1 is the utility model bypass automatic pressure modulating valve organigram.
Below in conjunction with Fig. 1 embodiment of the present utility model is done detailed explanation.
1, adjusting nut; 2, Regulation spring; 3, sleeve; 4, positioning seat; 5, spring seat; 6, drive link; 7, drive block; 8, bellows; 9, contiguous block; 10, setting sleeve; 11, steel ball; 12, valve body; 13, resistance tail mouth; 14, spring; 15, liquid inlet pipe; 16, drain pipe.
The utility model relates to a kind of bypass automatic pressure modulating valve, and valve body 12 is arranged, and connects the sleeve 3 of valve body, and adjusting nut 1 is installed in the upper end of sleeve, and adjusting nut heads on balance adjustment spring 2, and spring seat 5 is arranged under the spring, and the positioning seat 4 that cooperates with sleeve lining is arranged.Connect the bellows assembly parts by drive link 6, bellows 8, drive block 7, contiguous block 9, setting sleeve 10 etc. are arranged, drive link 6 can be made one with drive block 7, and bellows 8, contiguous block 9, setting sleeve 10 connect together with steel ball 11, and steel ball is attached to the resistance tail mouth 13 of liquid inlet pipe 15.This valve rotates adjusting nut 1 in use earlier, make 2 pairs of steel ball pressure of Regulation spring that rating value be arranged, promptly set up required pressure, when the head pressure of system surpasses the set pressure value, then this pressure pushes steel ball and bellows, thereby make the Regulation spring compression, beat a mouthful valve port, make refrigeration agent flow to low pressure line (drain pipe) through the outlet end of valve by valve port.
