Description
Technical field
The utility model relates to the fluid pressure controller spare that a kind of air-conditioning system is used, especially the pressure controller of automobile air-conditioning refrigeration agent.
Background technique
The pressure controller that existing air-conditioning system is used generally is the singlet switch, promptly use a diaphragm as pressure-sensing device, when signal pressure reaches setting value, the diaphragm upset, the drive push rod moves, push rod promotes the spring sheet action again, a pair of silver point is disconnected or connection, thereby disconnection or connection control circuit are to reach the control purpose.For example Chinese patent CN2246739Y discloses a kind of like this structure, and it is a singlet switch, has only the low-voltage variation function.Yet present air-conditioning system especially automotive air-conditioning system not only requires pressure controller that the low-voltage variation function is arranged; but also requiring to have high voltage protective and middle function of pressing instant action, this just requires pressure controller can move respectively to control different circuit when low pressure, high and medium voltage.
Summary of the invention
The purpose of this utility model is to provide a kind of and can moves in low pressure, can move respectively at high and medium voltage again, collects three pressure controllers that the singlet switch is an one.
In order to achieve the above object, the utility model is by the following technical solutions: a kind of pressure controller, electrical prongs with spring sheet and band silver point of housing, diaphragm, push rod, band silver point, has pipe joint on the housing, electrical prongs is fixed on the housing, three diaphragms are arranged in the housing, be respectively low pressure diaphragm, middle pressuring film plate and high pressure diaphragm; Three spring sheets are arranged in the housing, be respectively low pressure spring sheet, middle compression elasticity sheet and high-pressure elastomeric sheet; Be equipped with on the housing low pressure pin, high pressure pin, middle compression set pin and in press pin; Spacer is divided into pressure chamber and control chamber two-part with the inner chamber between housing and the pipe joint, pressuring film plate is contained on the middle wedge of band center hole in control chamber, middle wedge bottom places on the high pressure diaphragm of band center hole, high pressure diaphragm is contained on the high pressure seat of band center hole, the high pressure seat bottom places on the low pressure diaphragm, the high pressure seat bottom has the prominent cover that passes low pressure diaphragm center hole, and the external diameter periphery place of low pressure diaphragm is bearing on the supporting shoulder of housing endoporus; The center hole cunning of push rod and middle wedge is joined, an end of push rod can with side contacts under the middle pressuring film plate, the other end passes the center hole of the center hole of center hole, high pressure seat of high pressure diaphragm and low pressure diaphragm and can contact with middle compression elasticity sheet; Cover periphery in top is joined with the center hole cunning of high pressure seat, inner hole sleeve on push rod, the end that the top is overlapped can with side contacts under the high pressure diaphragm, the other end can contact with the high-pressure elastomeric sheet; The prominent cover of high pressure seat bottom is enclosed within the top and puts, and the end can contact with the low pressure spring sheet; The silver point of low pressure spring sheet is corresponding with the silver point of high-pressure elastomeric sheet, and the silver point of middle compression elasticity sheet is corresponding with the silver point of middle compression set pin.
After adopting said structure,, be respectively low pressure diaphragm, middle pressuring film plate and high pressure diaphragm owing in the housing three diaphragms are arranged; Also have three spring sheets in the housing, be respectively low pressure spring sheet, middle compression elasticity sheet and high-pressure elastomeric sheet; Have on the housing low pressure pin, middle compression set pin, in press pin and high pressure pin; And parts such as interior middle wedge, high pressure seat, push rod, the top of housing overlapped, prominent cover.This has just constituted three cover constructions of switch, and collecting three singlet switches is one, and the low pressure diaphragm overturns when low pressure, can make the prominent cover in bottom of high pressure seat promote the action of low pressure spring sheet, makes the silver point of low pressure spring sheet contact compressor operating with the silver point of high-pressure elastomeric sheet; In pressuring film plate when middle pressures, overturn, can make push rod promote in the compression elasticity sheet move, the silver point of middle compression elasticity sheet is contacted with silver point on the middle compression set pin, open fan; And high pressure diaphragm overturns when high pressure, then can make the top cover promote the action of high-pressure elastomeric sheet, makes the silver point of high-pressure elastomeric sheet separate close compressor with the silver point of low pressure spring sheet.So the utility model is controlled different circuit, to satisfy the needs of air-conditioning systems such as car air conditioner at low pressure, the medium and high pressure time-division work of not moving.Simultaneously the utility model with use three singlet switches to compare respectively also to have the cost of saving, little advantage takes up space.
