Problems solved by technology

In this way, when the overall force of the four-way reversing valve vibrates, the support cover will move relative to the bracket, the vibration of the support cover and the support will not be synchronized, and the resonance frequency will decrease, which will easily lead to capillary breakage and affect the overall performance of the valve.

Embodiment 1

[0032] Such as figure 1 , figure 2 , image 3 As shown, the pilot valve fixing structure provided by Embodiment 1 of the present invention includes a bracket 1 and a support cover 2 that cooperate with each other to fix the pilot valve 300 . The bracket 1 includes a connecting plate 13 , a first supporting plate 11 and a second supporting plate 12 , and the first supporting plate 11 and the second supporting plate 12 are respectively arranged on opposite sides of the connecting plate 13 and arranged in parallel. The support cover 2 includes a cover plate 21 and a sealing plate 22 formed by bending one side of the cover plate. The cover plate 21 is fixedly connected to the first support plate 11 , the cover plate 22 is fixedly connected to the second support plate 12 , and one end of the pilot valve 300 is arranged between the bracket 1 and the support cover 2 to realize fixing.

[0033] After the installation is completed, the support 1 , the support cover 2 and the pilot ...

Embodiment 2

[0047] Such as Figure 6 As shown, the difference between Embodiment 2 of the present invention and Embodiment 1 above is that the sealing plate 22 is provided with a larger lug 24 at the end away from the cover plate 21, and the lug is directly attached to the second supporting plate. 12, and realize the fixed connection between the lug 24 and the second support plate 12 by welding, so as to realize the fixed connection between the sealing plate 22 and the second support plate 12.

[0048] Other structures of Embodiment 2 of the present invention are the same as those described in Embodiment 1 above, so details will not be repeated here.

[0049] It can be understood that, in this embodiment, the fixing between the lug 24 and the second support plate 12 can also be realized by means of screw connection, riveting and the like.

Abstract

The invention discloses a pilot valve fixing structure and a four-way reversing valve, which belong to the field of valves. The fixing structure includes a bracket and a support cover that cooperate with each other to fix the pilot valve. The bracket includes a connecting plate, and the support cover includes a cover plate. It is characterized in that , the bracket also includes a first support plate and a second support plate respectively arranged on opposite sides of the connecting plate and arranged in parallel, the support cover also includes a sealing plate formed by bending one side of the cover plate, and the cover plate is fixedly connected to the The first support plate and the sealing plate are fixedly connected to the second support plate, and one end of the pilot valve is arranged between the bracket and the support cover to realize fixing. When the whole structure vibrates due to force during the working process, the bracket, support cover and pilot valve vibrate synchronously, and the three have the same resonance frequency, which can effectively avoid the capillary breakage caused by the low resonance frequency between the bracket and support cover. Ensure the overall stability of the valve structure, thereby ensuring the working stability of the valve structure and prolonging the service life of the valve structure.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a fixing structure of a pilot valve. In addition, the invention also relates to a four-way reversing valve. Background technique [0002] The four-way reversing valve is mainly composed of a main valve, a pilot valve and an electromagnetic coil. When working, the reversing of the main valve is realized through the joint action of the electromagnetic coil and the pilot valve, so as to realize the purpose of switching the fluid flow direction, and then make the heat exchange system It can be switched between two working states to realize the dual-purpose working purpose of cooling in summer and heating in winter. [0003] In the prior art, the pilot valve is generally fixedly arranged on the main valve. The Chinese utility model patent with the notification number CN 204553914U discloses an electromagnetic four-way reversing valve, wherein the driving valve is installed on the valv...
