Abstract
The utility model discloses an electromagnetic four-way reversing main valve which comprises a main valve body and a main valve seat. The main valve seat is installed on the main valve body. An installation hole matched with a copper connecting tube is formed in the main valve seat, chamfers are formed at the bottoms of the two ends of the main valve seat, and soldering flux filling grooves are formed in the two ends of the main valve base along the arc surfaces. Due to the fact that the soldering flux filling grooves are formed in the two ends of the main valve seat along the arc faces, the soldering flux filling grooves can be filled with soldering flux flowing in a scattered mode in the welding process of the main valve; due to the fact that the soldering flux filling grooves are not located within the piston motion inner wall range, the problem that because the soldering flux flows to the piston motion inner wall in a scattered mode, the welding and the performance are poor is solved; in addition, copper applied to the two ends of the main valve seat is reduced and production cost is saved.
Description
Technical field:
The utility model relates to the electromagnetism four-way change-over valve that air conditioner refrigerating industry is used, and especially relates to a kind of electromagnetism main valve of four-way reversing valve.
Background technique:
Electromagnetism four-way change-over valve is the important devices of heat pump type air conditioner, is applicable to central authorities, split, window air conditioner etc.The action of existing electromagnetism four-way change-over valve is to utilize height pressure reduction in system to drive main valve parts inner chamber piston to commutate by pilot valve, thereby realize conversion, realizes the conversion that refrigerant flows to.As shown in Figure 1: existing solenoid operated four-way valve main valve mainly comprises main valve body 01, is arranged on the component such as main valve seat 02, copper connecting tube (ESCD adapter) 03 and support on main valve body 01, and wherein, copper connecting tube 03 coordinates with the mounting hole 021 on main valve seat 02; See shown in Fig. 2 and Fig. 3: between its main valve seat 02 two ends of current solenoid operated four-way valve main valve and main valve body 01 by little chamfering 022 transition, be almost snug fit, during main valve welding, the easy cross flow of scolder is to main valve body 01 piston movement inwall, make piston cause valve body performance bad in when work and solder flux friction, affect conforming product rate; On the other hand, it is excessive that the copper material at main valve seat 02 two ends is filled face, causes waste of material, increases product cost.
Model utility content:
The purpose of this utility model is to provide the deficiency existing for prior art and a kind of new electromagnetism main valve of four-way reversing valve is provided, and it can avoid solder flux in main valve welding process to flow into piston movement inwall and cause main valve failure welding and the bad problem of performance.
For achieving the above object, electromagnetism main valve of four-way reversing valve of the present utility model includes main valve body and main valve seat, wherein, main valve seat is arranged on main valve body, on main valve seat, offer the mounting hole coordinating with copper connecting tube, the bottom at main valve seat two ends forms chamfering, and described main valve seat two ends offer solder flux filling slot along arc surface.
As technique scheme preferably, described solder flux filling slot is the rectangle fluting in main valve seat two terminal circle cambered surface.
As technique scheme preferably, described solder flux filling slot is the rounding fluting in main valve seat two terminal circle cambered surface.
As technique scheme preferably, described solder flux filling slot is the cutting fluting in main valve seat two terminal circle cambered surface.
As technique scheme preferably, the groove depth of described solder flux filling slot is less than 1/2 of main valve seat two terminal circle cambered surface thickness.
The beneficial effects of the utility model are: owing to offering solder flux filling slot at main valve seat two ends along arc surface, in main valve welding process, the solder flux of cross flow can be filled in solder flux filling slot, because solder flux filling slot is not within the scope of piston movement inwall, can effectively avoid the welding and the bad great question of performance that due to solder flux cross flow to piston movement inwall, cause; Can reduce on the other hand main valve seat two ends brass material consumption, save production cost.

Embodiment:
Therefore the following stated only, for embodying the preferred embodiment of the utility model principle, does not limit protection domain of the present utility model.
As shown in Figure 4: electromagnetism main valve of four-way reversing valve of the present utility model includes main valve body 10 and main valve seat 20, wherein, main valve seat 20 is arranged on main valve body 10, offers the mounting hole 21 coordinating with copper connecting tube 30 on main valve seat 20, and the bottom at main valve seat 20 two ends forms chamfering 22; In addition, main valve seat 20 two ends offer solder flux filling slot 23 along arc surface, and the groove depth of solder flux filling slot 23 is less than 1/2 of main valve seat 20 two terminal circle cambered surface thickness, to guarantee the intensity of main valve seat 20.
In the embodiment one shown in Fig. 5 to Fig. 7, solder flux filling slot 23 is the rectangle fluting in main valve seat 20 two terminal circle cambered surfaces.
In the embodiment two shown in Fig. 8 to Figure 10, solder flux filling slot 23 is the rounding fluting in main valve seat 20 two terminal circle cambered surfaces.
In the embodiment three shown in Figure 11 to Figure 13, solder flux filling slot 23 is the cutting fluting in main valve seat 20 two terminal circle cambered surfaces.
Owing to offering solder flux filling slot 23 at main valve seat 20 two ends along arc surface, in main valve welding process, the solder flux of cross flow can be filled in solder flux filling slot 23, because solder flux filling slot 23 is not within the scope of piston movement inwall, can effectively avoid the welding and the bad great question of performance that due to solder flux cross flow to piston movement inwall, cause; , can reduce on the other hand main valve seat 20 two ends brass material consumptions, save production cost.
