Description

Technical Field

[0001] This utility model relates to a valve body, and more specifically, to a proportional valve. Background Technology

[0002] Proportional valves are commonly used hydraulic components. They generally consist of a valve body and a control body. The valve body contains a valve core, a drive magnet, and a displacement sensor, while the control body typically includes a control circuit board, such as an amplifier circuit board.

[0003] There is a proportional valve, such as Figure 1 As shown, valve body 1 is equipped with plug 3, and control body 2 is equipped with wire 01. The end of wire 01 is equipped with a connection terminal, and the connection terminal is provided with socket 4. When valve body 1 and control body 2 are combined, plug 3 and socket 4 need to be connected first, and then the stacking and pressing process of valve body 1 and control body 2 is completed, which is very inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a proportional valve in which the plug and socket are first fixed on the mating surfaces of the valve body and the control body respectively. When the valve body and the control body are stacked and assembled, the mating surfaces of the two are joined together, thereby realizing the insertion of the socket and the plug, making the stacking process of the valve body and the control body simpler.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A proportional valve includes a valve body and a control body, and further includes a plug and a socket respectively disposed on the mating surfaces of the valve body and the control body; the plug is fixed on the mating surface; the socket is opened in the socket and the socket is fixed on the mating surface; when the valve body and the control body are pressed together, the plug and the socket on the mating surface are correspondingly inserted.

[0006] Preferably, there are multiple sets of corresponding sockets and plugs.

[0007] Preferably, the valve body is provided with a positioning protrusion and the control body is provided with a positioning groove; when the valve body and the control body are pressed together, the positioning protrusion is inserted into the positioning groove.

[0008] Preferably, the valve body and the control body are fixed with screws.

[0009] Preferably, the valve body is fixed with a limiting strip that protrudes relative to its mating surface. There are two limiting strips, which are located on two opposite sides of the valve body. The height of the limiting strip protruding relative to the mating surface of the valve body is greater than the extension of the plug. The limiting strip is located on one side of the valve body. A limiting groove matching the limiting strip is opened on the side of the control body. When the valve body and the control body are pressed together, the limiting strip is inserted into the limiting groove.

[0010] In summary, this utility model has at least one of the following beneficial effects: The plug and socket are located on the valve body and control body respectively. The positions of the plug and socket are fixed. When the valve body and control body are stacked and pressed together, the plug and socket can be precisely connected and inserted without the need for pre-connection of the plug and socket, making the assembly and installation of the proportional valve more convenient.

[0011] The operating conditions for the proportional valve assembly installation are as follows: assembly in the production workshop and assembly on the hydraulic valve plate after subsequent maintenance and cleaning. Attached Figure Description

[0014] The present invention will be further described in detail below with reference to the accompanying drawings.

[0015] Example 1, a proportional valve, refer to Figures 2-4 It includes a valve body 1 and a control body 2, with the control body 2 being stacked and pressed on top of the valve body 1.

[0016] A plug 3 is fixed on the upper surface of the valve body 1. There are three sets of plugs 3, which are used for power connection and electrical signal connection.

[0017] The plug 3 is fixed with a base, which is glued to the valve body 1.

[0018] The upper surface of the socket where plug 3 is located is the mating surface, such as Figure 2 As shown, the mating surface is the first mating surface 11.

[0019] The first mating surfaces 11 of the three plugs 3 are on the same plane.

[0020] Figure 3 In the middle, a socket is glued and fixed to the lower surface of the control body 2, and the socket has a socket 4; The side of the socket facing the valve body 1 is the mating surface, which is the second mating surface 21. The second mating surfaces 21 of the three sockets are on the same plane.

[0021] When valve body 1 and control body 2 are pressed together, the plug 3 and socket 4 on the two opposing mating surfaces are inserted into each other; then valve body 1 and control body 2 are fixed with screws 6.

[0022] Example 2, a proportional valve, differs from Example 1 in that, as described below... Figure 4 and Figure 5 A positioning protrusion 51 is fixed on the upper surface of the valve body 1. The positioning protrusion 51 is a raised rectangular metal block, and the upper surface of the positioning protrusion 51 is lower than the upper surface of the first mating surface 11. The control body 2 is provided with a positioning groove 52. The positioning groove 52 is formed on the lower surface of the control body 2. Reference Figure 4 When the valve body 1 and the control body 2 are pressed together, the positioning protrusion 51 is inserted into the positioning groove 52. This design makes it easy for employees to observe whether the valve body 1 and the control body 2 are installed correctly. Secondly, after the positioning protrusion 51 and the positioning groove 52 are correctly inserted, the swinging and loosening of the control body 2 and the valve body 1 in the left and right directions can be restricted.

[0023] Example 3, a proportional valve, differs from Example 1 or Example 2 in that, as described above... Figures 6-8 The valve body 1 is fixed with a limiting strip 71 that protrudes relative to its own mating surface, that is, a limiting strip 71 that protrudes relative to the first mating surface 11.

[0024] The limiting strip 71 is a metal strip, which is bonded and fixed to the side of the valve body 1, and the limiting strip 71 protrudes vertically upward.

[0025] There are two limit bars 71, and the two limit bars 71 are located on two opposite sides of the valve body 1 respectively; The limiting strip 71 is located on one side of the valve body 1. In this embodiment, there are three sockets, and the limiting strip 71 is close to the rightmost plug 3. The side of the control body 2 is provided with a limiting groove 72 that matches the limiting strip 71. Since the two limiting strips 71 are arranged opposite each other and the limiting strip 71 is close to the rightmost plug 3, the control body 2 and the valve body 1 can only be mated and pressed together in one direction. If the control body 2 is rotated 180 degrees in the horizontal plane, the limiting strip 71 and the limiting groove 72 will not be aligned and matched. The height of the limit strip 71 protruding from the mating surface of the valve body 1 is greater than the extension of the plug 3; that is, the height of the limit strip 71 is higher than the height of the plug 3. If the limit strip 71 and the limit groove 72 are not aligned, the limit strip 71 will contact the lower surface of the control body 2 in advance. This avoids the impact of the lower surface of the control body 2 on the plug 3 when the employee makes a mistake during assembly, and has a good protection function for the plug 3.

[0026] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
