Description
Technical field
The utility model relates to solenoid directional control valve, and especially a kind of being applied in is used in the air-conditioning system switching the electromagnetism four-way change-over valve that the air-conditioning system refrigerant flows to the switching of realization air-conditioning system cooling and heating pattern, in particular, relates to the leading truck of electromagnetism four-way change-over valve.
Background technique
The electromagnetism four-way change-over valve is mainly used to switch the flow direction of air-conditioning system refrigerant, thereby makes air conditioner play the switching of cooling and heating, has the structure of electromagnetism four-way change-over valve now as shown in Figure 1, and its working principle is as follows:
Air conditioner refrigeration cycle: when electromagnetic coil 03 outage, be divided into two-way from air-conditioning compressor relief opening high pressure refrigerant out, one the tunnel arrives the right piston cavity of four-way valve behind the D of pilot valve capillary tube 01, C capillary tube 02, make right piston cavity form high pressure, pushing piston parts 12 are moved to the left, the leading truck 10 band movable sliders 11 that link to each other with piston element 12 simultaneously also are moved to the left, and the E adapter 06 and the S that finally make slide block 11 cover four-way valve take over 07, and make its connection; Condenser, throttle element, the vaporizer that passes through again air-conditioning system after 08 taken over through the D of four-way valve adapter 09, C in another road, takes over 06 to S adapter 07 from E at last and gets back to the compressor air suction mouth, forms a refrigeration cycle.
Air conditioner heat-production circulation: when electromagnetic coil 03 energising, be divided into two-way from air-conditioning compressor relief opening high pressure refrigerant out, one the tunnel through pilot valve D capillary tube 01, E capillary tube 04, arrive the left piston chamber of four-way valve, make the left piston chamber form high pressure, the piston element 12 that promotes left end moves right, and the leading truck 10 band movable sliders 11 that link to each other with piston element 12 simultaneously also move right, final so that slide block 11 covers S adapter 07 and the C adapter 08 of four-way valve, and make its connection; Another road is taken over 09, is taken over 06 to E through the D of four-way valve, passes through successively vaporizer, throttle element, the condenser of air-conditioning system again, takes over 07 from C adapter 08 to S at last and gets back to the compressor air suction mouth, forms one and heats circulation.
Be understood that by above-mentioned working principle, leading truck is in air-conditioning system cooling and heating pattern handoff procedure, play a key effect, at present, common leading truck comprises plate-like body, be provided with runner hole and slide block slot in plate-like body, the two ends of plate-like body respectively are provided with two flangings of opposite direction, and flanging is provided with tapped hole.Increase along with the four-way valve body diameter, the diameter of piston element is corresponding increase also, the pressure that four vertical flangings of leading truck bear increases, can cause the flanging of leading truck to deform even rupture, perhaps because the worm tooth number causes screw strength less the sliding tooth of screw occurs not, final so that four-way change-over valve can not commutate and lose efficacy.
It is that " CN200710068986.6 ", name are called the patent of invention of " piston link lever of four-way reversing valve " that China national Department of Intellectual Property discloses the patent No. on September 22nd, 2010, this patent increases the flanging bending resistance by the mode of connection reinforcement plate on flanging, but because every stiffening plate all is independent installation, assembling procedure is comparatively loaded down with trivial details, and efficiency of assembling is low; And the flanging height is lower, interferes in the time of can causing flanging to be connected with the stiffening plate screw behind the use stiffening plate, causes the assembling difficulty.
