Abstract
Description
Technical Field
[0001] This utility model relates to the field of electromagnetic directional valve technology, specifically a cross-type electromagnetic four-way directional valve. Background Technology
[0002] Electromagnetic reversing valves are key components of refrigeration equipment, mainly used in heat pump air conditioners, heat pump water heaters, and other equipment to achieve switching between cooling and heating modes.
[0003] Currently, there are certain drawbacks in the repair and replacement process of the four-way reversing valve inside the air conditioner. Because the distance between the three parallel pipe sections on the four-way valve and the multiple pipes inside the air conditioner is different, repair personnel usually need to use pliers to expand the pipe sections inside the four-way valve outward until the expanded pipe sections of the four-way valve are perfectly matched with the multiple pipes inside the air conditioner outdoor unit. However, this process will cause some damage to the pipe wall of the four-way valve, and the plating of the pipe wall will also be damaged.
[0004] In view of this, a cross-type electromagnetic four-way reversing valve was designed to solve the above problems. Utility Model Content
[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.
[0006] Therefore, the technical solution adopted by this utility model is as follows: A cross-type electromagnetic four-way reversing valve includes a valve body, a pipe clamping mechanism mounted outside the valve body, a temperature control component mounted outside the pipe clamping mechanism, and a pipe spacing adjustment component mounted on the valve body. The pipe clamping mechanism includes a base, with two first clamps sleeved on the outside of the base. Bolts are installed inside the first clamps, and second clamps are installed outside the bolts. Two limiting sleeves are fixedly installed on the front of the base, and hexagonal threaded sleeves are movably installed at the outer ends of the limiting sleeves. A bidirectional screw is installed in the internal thread of the hexagonal threaded sleeve. The pipe spacing adjustment component includes an inner support plate and two pipe clamps movably installed on three pipe sections of the valve body. Four symmetrically distributed sliding rods are fixedly installed on both sides of the inner support plate, with two adjacent sliding rods inserted into the pipe clamps. A pressing block is movably installed between the inner support plate and the two pipe clamps. An end plate is fixedly installed at the inner end of the pressing block, and the outer end of the bidirectional screw is movably installed in the end plate.
[0007] In a preferred embodiment, the present invention can be further configured such that: two symmetrically distributed pads are fixedly installed at both ends of the base, a support rod is fixedly installed inside the pad, and a pad block is fixedly installed inside the support rod.
[0008] In a preferred embodiment, the present invention can be further configured such that: the base has three through holes inside, and the three pipe segments of the valve body are adapted to be inserted into the three through holes inside the base.
[0009] In a preferred embodiment, the present invention can be further configured as follows: the temperature control component includes a first cooling cover, four symmetrically distributed guide pipes are fixedly installed at both ends of the first cooling cover, and a second cooling cover is installed at the outer ends of two adjacent guide pipes, and there are two second cooling covers, one of which is fixedly installed with a water inlet pipe and the other is fixedly installed with a drain pipe.
[0010] In a preferred embodiment, the present invention can be further configured such that: a pipe sleeve is fixedly installed on the pipe clamp plate, and a triangular oblique opening is provided in the middle of the inner side of the pipe clamp plate.
[0011] In a preferred embodiment, the present invention can be further configured such that the inclined surface of the extrusion block on the side away from the inner support plate is adapted to fit onto the triangular inclined opening.
[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. This utility model installs a tank clamping mechanism on the outside of the valve body and uses the pipe clamping mechanism to adjust the pipe spacing of the pipe spacing adjustment component. The hexagonal screw sleeve is adjusted by a wrench to drive the bidirectional screw to stretch and compress the block. Finally, the pipe clamp plate will extend outward, and the pipe section on the valve body can be stretched outward accordingly. This can improve the effective adaptation between the valve body and multiple pipes in the air conditioner outdoor unit without damaging the valve body pipe section structure.
[0013] 2. This utility model uses an externally mounted temperature control component on the valve body. After the new valve body is installed on multiple pipes inside the air conditioner, liquid is injected into the inlet pipe until the two second cooling covers and one first cooling cover are filled with coolant. This will ultimately provide heat insulation protection for the outer surface of the valve body, preventing the high temperature generated by subsequent welding from damaging the internal components of the valve body.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0017] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.
[0018] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a cross-type electromagnetic four-way reversing valve.
[0019] Example 1: Combination Figures 1 to 4 As shown, the present invention provides a cross-type electromagnetic four-way reversing valve, including a valve body 100, a pipe clamping mechanism 200 installed outside the valve body 100, a temperature control component 300 installed outside the pipe clamping mechanism 200, and a pipe spacing adjustment component 400 installed on the valve body 100. The pipe clamping mechanism 200 is used to provide an effective support carrier for the temperature control component 300 and the pipe clamping mechanism 200. The temperature control component 300 is used to provide heat insulation protection for the valve body 100. The pipe spacing adjustment component 400 is used to adjust the pipe spacing of the pipe sections inside the valve body 100.
[0020] The tube clamping mechanism 200 includes a base 210, two first clamps 250 are sleeved on the outside of the base 210, a bolt 2502 is installed inside the first clamp 250, a second clamp 2501 is installed outside the bolt 2502, two limiting sleeves 220 are fixedly installed on the front of the base 210, a hexagonal threaded sleeve 2201 is movably installed on the outer end of the limiting sleeve 220, and a two-way screw 2202 is installed on the internal thread of the hexagonal threaded sleeve 2201. Two symmetrically distributed pads 2101 are fixedly installed at both ends of the base 210. A support rod 230 is fixedly installed inside the pad 2101, and a pad block 240 is fixedly installed inside the support rod 230. The base 210 has three through holes inside, and the three pipe sections of the valve body 100 are adapted to be inserted into the three through holes inside the base 210. The pipe spacing adjustment assembly 400 includes an inner support plate 410 and two pipe clamp plates 430 movably installed on three pipe sections of the valve body 100. Four symmetrically distributed slide rods 420 are fixedly installed on both sides of the inner support plate 410. Two adjacent slide rods 420 are inserted into the pipe clamp plates 430. A pressing block 440 is movably installed between the inner support plate 410 and the two pipe clamp plates 430. An end plate 4401 is fixedly installed on the inner end of the pressing block 440, and the outer end of the bidirectional screw 2202 is movably installed in the end plate 4401. A pipe sleeve 4301 is fixedly installed on the pipe clamp plate 430, and a triangular oblique opening is provided in the middle of the inner side of the pipe clamp plate 430. The inclined surface of the extrusion block 440 on the side away from the inner support plate 410 is adapted to fit onto the triangular bevel.
[0021] Beforehand, the two hexagonal threaded sleeves 2201 are adjusted with a wrench. As the hexagonal threaded sleeves 2201 rotate, the double-acting screw 2202 extends along the inside of the hexagonal threaded sleeves 2201. Finally, the end of the double-acting screw 2202 away from the temperature control component 300 extends into the inner cavity of the limiting sleeve 220. The end plate 4401 and the pressing block 440 pulled by the double-acting screw 2202 are squeezed into the inner support plate 410 and the pipe clamp plate 430. As the pressing block 440 continues to extend under pressure, the two pipe clamp plates 430 are pushed laterally. Finally, the two outwardly extended pipe clamp plates 430 adjust the spacing of the parallel pipe sections of the valve body 100 until the spacing of multiple pipe sections in the valve body 100 matches the spacing of multiple pipes in the outdoor unit of the air conditioner.
[0022] Example 2: Combination Figure 2 As shown, in the above embodiment, the temperature control component 300 includes a first cooling cover 310, four symmetrically distributed guide pipes 320 are fixedly installed at both ends of the first cooling cover 310, and a second cooling cover 330 is installed at the outer end of two adjacent guide pipes 320. There are two second cooling covers 330, one of which is fixedly installed with a water inlet pipe 340, and the other is fixedly installed with a drain pipe 350. Preferably, the first cooling cover 310 is installed on the outside of the base 210, and the inner wall of the first cooling cover 310 and the inner walls of the two second cooling covers 330 are adapted to fit against the outer surface of the valve body 100. As the coolant enters one of the second cooling covers 330 through the water inlet pipe 340, the coolant will be transferred to the first cooling cover 310 and the other second cooling cover 330 through the guide pipe 320. Finally, the first cooling cover 310 and the two second cooling covers 330 filled with coolant will provide temperature control protection for the valve body 100 during welding.
[0023] The working principle and usage process of this utility model are as follows: When it is necessary to replace the old valve body of the air conditioner, the cover plate of the air conditioner is removed, and then the welding area on the old valve body is heat-fused with a welding torch. A replacement valve body is then pre-installed in multiple pipe sections of the air conditioner. Because the spacing between the multiple pipes reserved inside the outdoor unit differs from the spacing between the multiple pipe sections of the valve body, in order to improve the compatibility and connection between the new valve body and the multiple pipes inside the outdoor unit, a wrench is used to adjust the two hexagonal threaded sleeves 2201 until the two double-acting screws 2202 retract along the inside of the two hexagonal threaded sleeves 2201. Finally, the double-acting screws 2202 will extend into the inside of the limiting sleeve 220. The end plates 4401 and the compression blocks 440 installed at the outer ends of the two double-acting screws 2202 will be squeezed along the inside of the pipe clamp plate 430 and the slide rod 420. Finally, the squeezed pipe clamp plate 430 will push the pipe section of the valve body 100 to expand outward until the expanded pipe section of the valve body 100 can be quickly adapted to the multiple pipes inside and outside the air conditioner.
