Abstract

An air-conditioner pressure adjustment unloading valve comprises a valve body, connected to an induction pipe and an outlet pipe, a spool is arranged in the valve body, which accommodates an auxiliary spring, the valve body is connected with a film retaining bracket for mounting the films, the film retaining bracket is connected with an adjustment barrel in which an pressure regulating spring is arranged.

Description

Pressure regulating Unloading valve of air conditioner
Technical field
The present invention relates to the air conditioner accessory, particularly relate to the adjusting unloading valve of crossing high voltage protective (the refrigeration system delivery pressure is too high) in the air conditioner.
Background technique
The use of air conditioner is very extensive, and in the office space, the teahouse, hotel, and family etc. is widely used.Air conditioner under normal circumstances reaches setting temperature meeting autostop; then start automatically again; but after the critical piece when refrigeration (perhaps heating) system---compressor occurs unusually; can produce high pressure; compressor is jumped machine automatically; and generally in half an hour, can not start behind the jumping machine, the frequent starting of compressor causes damage easily simultaneously, seriously influences the working life of compressor.
Summary of the invention
The present invention is in order to overcome the defective of prior art, a kind of pressure regulating Unloading valve of air conditioner is provided, and the technological scheme of this pressure regulating Unloading valve of air conditioner is: a valve body is arranged, and valve body connects inlet tube and outer pipe, spool is installed in the valve body, spool has secondary spring, it is characterized in that valve body connects the diaphragm fixed base, installs diaphragm in the diaphragm fixed base, connect on the diaphragm fixed base and regulate tube, regulate in the tube pressure adjusting spring is installed, the top plug is arranged under the pressure adjusting spring, upper and lower and the top plug and spool of diaphragm contact.Its described diaphragm fixed base is down diaphragm fixed base and upper diaphragm fixed base, valve body with regulate tube by upper and lower diaphragm fixed base to being welded into one, middle by diaphragm body cavity with regulate tube inner chamber and separate.There is the adjusting plug screw upper end of its pressure adjusting spring, at first matches with the spring top flat in the lower end of pressure adjusting spring, and the spring top flat is connected with diaphragm top plug by steel ball, and diaphragm top plug contacts with diaphragm down.Be shaped on spring groove in valve body, spring groove is opened on the valve body valve pocket, and secondary spring is installed in the spring groove, matches with clamp in the secondary spring upper end.Its spool can be made one with clamp.Spool is to adopt stainless steel material made.This unloading valve is mainly used in the high voltage protective of crossing in the air conditioner.When air-conditioning system pressure did not reach the cracking pressure value of setting, because pressure adjusting spring acts on diaphragm and withstands spool, unloading valve was in closed condition; And when air-conditioning system pressure reaches the cracking pressure value of setting (setting); this moment, the fluid from inlet tube arrived in the following diaphragm fixed base from the valve pocket of valve body, and acted on diaphragm, and fluid force is greater than pressure adjusting spring pressure; make bullet on the diaphragm; secondary spring drives spool and rises, and the instantaneous valve port of opening makes fluid flow to low pressure line by valve port through outer pipe; reach the off-load purpose; need not jump the machine pressure release, reduce the frequent starting of main frame, protect compressor effectively.And this unloading valve adopts mechanical structure, does not need the signal transmission, the reliability height, and control is accurate, stable; Adopt the shunting release, work on, do not influence the air conditioner refrigerating operation at the stress-relief process compressor.
Description of drawings
Fig. 1 is a pressure regulating Unloading valve of air conditioner structural representation of the present invention.
Embodiment
The invention discloses the pressure adjusting unloading valve of crossing high voltage protective that a kind of air conditioner is used; a valve body 2 is arranged; valve body connects inlet tube 3 and outer pipe 1; inlet tube 3 connects high-pressure duct system, and outer pipe 1 connects low pressure line, and spool 5 is installed in the valve body; spool preferably adopts the stainless steel material manufacturing; spool 5 the higher authorities connect clamp 6, but also spool 5 and clamp 6 can be made one, and spool mobile has secondary spring 4.Main feature is that valve body 2 tops connect the diaphragm fixed base, described diaphragm fixed base can be made into down diaphragm fixed base 15 and upper diaphragm fixed base 13, diaphragm 14 is installed in upper and lower diaphragm fixed base, tube 8 is regulated in one of the top connection of upper diaphragm fixed base 13, reliable in order to connect, good seal performance, can with valve body 2 with regulate tube 8 and 13,15 pairs of upper and lower diaphragm fixed bases and be welded into one, by the diaphragm 14 of centre separating between body cavity and the adjusting tube inner chamber.Pressure adjusting spring 7 is installed in regulating tube 8, top plug 12 (pressure adjusting spring directly connects the top plug) is arranged under the pressure adjusting spring, so upper and lower and the top plug 12 and spool 5 of diaphragm 14 contact.Can there be the plug screw 9 of adjusting the upper end of pressure adjusting spring 7, regulates plug screw 9 and the threaded adjusting of regulating tube 8, determines the setting pressure of pressure adjusting spring 7.More reliable for the pressure that pressure adjusting spring is transmitted, can at first match in the lower end of pressure adjusting spring 7 with spring top flat 10, spring top flat 10 is connected with diaphragm top plug 12 by steel ball 11, and the diaphragm top is filled in 12 times and is contacted with diaphragm 14.Can be shaped on spring groove 16 in valve body 2, spring groove 16 lower aperture are in the valve pocket 17 of valve body, and secondary spring 4 is installed in the spring groove 16, match with clamp 6 in secondary spring 4 upper ends.Fluid in pressure duct is from inlet tube 3 to valve pocket 17, arrive in the following diaphragm fixed base 15 through spring groove 16, and act on diaphragm 14, during greater than pressure adjusting spring 7 pressure, make bullet on the diaphragm 14 at hydrodynamic pressure, the pressure adjusting spring decrement increases, secondary spring 4 drives spool 5 and rises, spool 5 breaks away from off-load valve port 18, makes fluid flow to outer pipe 1 to low pressure line by off-load valve port 18, reaches the off-load purpose.When high-pressure duct system pressure reduces, to close at pressure adjusting spring 7 effect lower valves, circulation so repeatedly makes compressor keep normal operation.
