Description
Technical field
The utility model belongs to refrigeration control field, relates to a kind of four-way change-over valve that is used for cooling cycle system, is specifically related to a kind of main valve of four-way change-over valve.
Background technique
Existing four-way change-over valve mainly is made up of electromagnetic coil, pilot valve and main valve.In control procedure, realize the commutation of main valve by the acting in conjunction of electromagnetic coil and pilot valve, switching the circulating direction of refrigeration working medium, thereby make heat pump type air conditioner in refrigeration with heat between two kinds of working staties and switch, realize the refrigeration in summer, heat the purpose of dual-use winter.
Fig. 1 is the common main valve structural representation that is applied to the four-way change-over valve in the refrigeration system.The valve body 102 of the main valve 100 of four-way change-over valve is welded respectively at two ends by a metal tube cylindraceous that an end cap 109 constitutes, it forms an airtight valve pocket, and the two ends of the connecting rod 103 in the valve pocket are fixedly connected with two piston elements 101 by mounting screw.Two piston elements 101 are with airtight main chamber 107, left chamber 108/ and the right chamber 109 of being separated into of the valve pocket of valve body 102.The valve seat 105 ' that has " D " shape structure of identical arc section with metal tube cylindraceous is welded on the metal tube of main chamber's 107 interior cylindrical, and spool 104 butt valve seats 105 ' are made slide relative.Take over 106c, take over 106s and take over that 106e is welded on that valve seat 105 ' is gone up and be communicated with, take over 106d and be welded on the metal tube cylindraceous and and be communicated with main chamber 107 with main chamber 107.Valve body, valve seat and a plurality of adapter weld together the formation valve body parts, take over 106d and the port of giving vent to anger of compressor 110 and are communicated with, take over 106s and the suction port of compressor 110 and be communicated with, take over 106e and be communicated with, take over 106c with indoor heat converter 140 and be communicated with outdoor heat converter 120.
Like this, the piston element 101 by main valve 100 inside drives spools 104 and slides with respect to valve seat 105 ', thus the refrigeration of realization and heat two kinds of switchings between the working state.When system need switch to the refrigeration work state, spool 104 slides into the left side, take over 106e and take over 106s connection, adapter 106d and take over the 106c connection, this moment, the refrigeration agent circulation path of internal system was: compressor 110 → adapter 106d → adapter 106c → outdoor heat converter 120 → throttle element 130 → indoor heat converter 140 → adapter 106e → meta adapter 106s → compressor 110; When system need switch to when heating working state, spool 104 slides into right side pipe 106c and takes over 106s to be communicated with, to take over 106d and take over 106e and is communicated with, and the refrigeration agent circulation path of this moment is: compressor 110 → adapter 106d → adapter 106e → indoor heat converter 140 → throttle element 130 → outdoor heat converter 120 → adapter 106c → adapter 106s → compressor 110.
Fig. 2 is the valve body parts structural drawing of prior art, and Fig. 3 is a partial enlarged drawing among Fig. 2.In this structural drawing, be processed with a plurality of attachment holes on the valve seat, each attachment hole is taken over corresponding with connection respectively.Bottom at attachment hole has stepped part, and attachment hole is communicated with by step hole with spool.When welding, place weld-ring in stepped part earlier, then adapter is pressed into the attachment hole of valve seat, make the step surface butt of taking over end face and valve seat and weld-ring is melted and implement welding by high temperature.
The four-way valve main valve structure of prior art, under the situation of accessory size fluctuation, may produce following situation: 1) adapter is not press-fit into place, because gapped existence, this moment, weld-ring was not clamped by valve seat and adapter, weld-ring can teetertotter, tilt, and influences sprawling and permeate behind the solder fusing, and then welding quality is caused a hidden trouble; 2) take over end face or valve seat orifice bottom surface injustice, cause weld-ring only local clamped, influence sprawling and permeate behind the solder fusing, and then welding quality is caused a hidden trouble; 3) if scolder can not fully permeate, pile up at the nozzle inner wall root, perhaps the weld-ring deliquescing is hung down cross-arm in hole central authorities, can directly influence the effective drift diameter of valve seat orifice, causes the valve seat latus rectum to diminish, and then influences the flow of air-conditioning system, causes the air-conditioning system decreased performance.
