Description

Technical Field

[0001] This utility model belongs to the field of valve equipment, and specifically relates to an electro-hydraulic valve and a leak-proof structure. Background Technology

[0002] Electro-hydraulic valves are devices that use electrical signals to control the flow of fluid and regulate its flow rate via hydraulic oil. However, current electro-hydraulic valves are prone to leakage during use. Leakage occurs when fluid continues to flow through the gap between the valve body and the pipeline body even when the valve is closed. This is caused by the long-term erosion and wear of the connection points by the fluid, leading to decreased precision in the fit. For example, under high pressure and high flow rate conditions, wear is accelerated, increasing the risk of leakage. This results in poor sealing at the connection points and wear on the sealing components due to frequent internal structural movements.

[0003] Conventional solutions include improving machining precision to make the valve core and seat fit more precisely and reduce wear. However, this significantly increases machining costs, and long-term use still cannot prevent leakage caused by wear. Alternatively, more wear-resistant and corrosion-resistant materials can be used to make valve cores, seats, and other components. However, these materials are expensive, which significantly increases valve costs, and they cannot fundamentally eliminate leakage. Therefore, a new structure is needed to solve the above-mentioned technical problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an electro-hydraulic valve and a leak-proof structure to solve the problems mentioned in the background technology.

[0005] This utility model is achieved through the following technical solution: an electro-hydraulic valve and a leak-proof structure, comprising: a valve assembly and a sealing assembly, wherein the outer surface of the valve assembly is fitted with a sealing assembly for leak prevention via a pipe fitting, the valve assembly includes a valve body for installing the pipe fitting, and an electro-hydraulic component is fitted on the upper surface of the valve body for controlling the valve core inside the valve body, the sealing assembly includes a first sealing element and a second sealing element for leak prevention, the first sealing element and the second sealing element being mutually sealed and clamped together.

[0006] In a preferred embodiment, two pipe fittings are symmetrically installed on the front and rear surfaces of the valve body, respectively. Each pipe fitting includes a pipe body and a sealing bolt. The pipe body is installed on the front and rear surfaces of the valve body by the sealing bolts.

[0007] In a preferred embodiment, a valve core is installed through the right side surface of the valve body. The electro-hydraulic component includes a control block and an electromagnetic block. A control block is integrally formed on the upper surface of the valve body. Control components are installed on the left and right surfaces of the control block to control the valve core in conjunction with the electromagnetic block.

[0008] In a preferred embodiment, an electromagnetic block is integrally formed on the upper surface of the control block, and an electromagnetic component is installed on the left and right surfaces of the electromagnetic block to work with the control block to control the valve core inside the valve body.

[0009] In a preferred embodiment, the sealing element includes a sealing ring and a connecting ring. The sealing ring is integrally formed on the outer surface of the pipe body. The inner surface of the sealing ring is not flush with the front surface of the pipe body. The connecting ring is integrally formed on the outer edge of the front surface of the sealing ring. The front surface of the connecting ring is flush with the front surface of the sealing ring.

[0010] In a preferred embodiment, a rubber pad is bonded to the front surface of the first connecting ring, and the second sealing element includes a second sealing ring, a second connecting ring, and a sealing pipe. The second connecting ring is structurally matched with the first connecting ring, and a sealing pipe is installed on the front surface of the second connecting ring. The second sealing ring is installed at the center of the front surface of the second connecting ring.

[0011] In a preferred embodiment, a sealing gasket is glued to the surface of the second sealing ring and the second connecting ring away from the sealing pipe. The second sealing ring is snapped inside the first sealing ring. The first connecting ring and the second connecting ring are connected to each other by bolts.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting a sealing component, the outer surface of the valve component is equipped with a sealing component for leak prevention through a pipe fitting. The sealing component includes a first sealing component and a second sealing component for leak prevention. The first sealing component and the second sealing component are mutually sealed and snapped together. In use, the first sealing component and the second sealing component are mutually snapped together to form a double sealing structure, which greatly reduces the possibility of fluid leakage, effectively prevents leakage, and ensures the stability and normal operation of the system.

[0013] 2. By setting up a valve assembly, which includes a valve body for installing pipe fittings, and an electro-hydraulic component installed on the upper surface of the valve body to control the valve core inside the valve body, the valve core can be accurately received and responded to by the electro-hydraulic component during use. This allows for precise adjustment of the valve opening, meeting the needs for fine control of parameters such as flow and pressure under different working conditions. For example, in an automated production line, the flow of the hydraulic system can be precisely adjusted to ensure the stability and accuracy of equipment operation. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 3 This utility model provides a technical solution: an electro-hydraulic valve and a leak-proof structure, including: a valve assembly and a sealing assembly. The outer surface of the valve assembly is fitted with a leak-proof sealing assembly via a pipe fitting 120. The valve assembly includes a valve body 100 for mounting the pipe fitting 120. An electro-hydraulic component is installed on the upper surface of the valve body 100 for controlling the valve core 110 inside the valve body 100. The sealing assembly includes a first seal and a second seal for leak prevention. The first seal and the second seal are mutually sealed and clamped together.

[0022] Please see Figures 1 to 3As the first embodiment of this utility model: two pipe fittings 120 are symmetrically installed on the front and rear surfaces of the valve body 100, respectively. The pipe fitting 120 includes a pipe body 122 and a sealing bolt 121. The pipe body 122 is installed on the front and rear surfaces of the valve body 100 respectively through the sealing bolt 121.

[0023] A valve core 110 is installed through the right side surface of the valve body 100. The electro-hydraulic components include a control block 130 and an electromagnetic block 140. The control block 130 is integrally formed on the upper side surface of the valve body 100. Control components 131 are installed on the left and right sides of the control block 130 to control the valve core 110 in conjunction with the electromagnetic block 140.

[0024] An electromagnetic block 140 is integrally formed on the upper surface of the control block 130. An electromagnetic component 141 is installed on the left and right surfaces of the electromagnetic block 140, which works with the control block 130 to control the valve core 110 inside the valve body 100.

[0025] During use, the valve core 110 is controlled by electro-hydraulic components, which can accurately receive and respond to electrical signals, enabling precise adjustment of the valve opening. This meets the needs for fine control of parameters such as flow and pressure under different working conditions. For example, in automated production lines, it can precisely adjust the flow of the hydraulic system to ensure the stability and accuracy of equipment operation (the specific connection principle and working principle of the valve components are existing technologies, and users can select and use them according to their actual situation, which will not be elaborated here).

[0026] Please see Figures 1 to 3 As a second embodiment of the present invention: the sealing element includes a sealing ring 200 and a connecting ring 210. The sealing ring 200 is integrally formed on the outer surface of the pipe body 122. The inner surface of the sealing ring 200 is not flush with the front surface of the pipe body 122. The connecting ring 210 is integrally formed on the outer edge of the front surface of the sealing ring 200. The front surface of the connecting ring 210 is flush with the front surface of the sealing ring 200.

[0027] A rubber gasket is glued to the front surface of the connecting ring 210. The second seal includes a second sealing ring 240, a second connecting ring 250, and a sealing pipe 230. The structure of the second connecting ring 250 matches that of the first connecting ring 210. The sealing pipe 230 is installed on the front surface of the second connecting ring 250, and the second sealing ring 240 is installed at the center of the front surface of the second connecting ring 250.

[0028] Sealing ring 240 and connecting ring 250 are bonded with sealing gaskets on the side away from sealing pipe 230. Sealing ring 240 is snapped inside sealing ring 1 200. Connecting ring 1 210 and connecting ring 250 are connected to each other by bolts. Sealing ring 1 200, sealing ring 240, pipe body 122 and sealing pipe 230 are interconnected.

[0029] In use, the user first connects one end of the sealing pipe 230 to the equipment being used. (When connecting the sealing pipe 230 to the equipment, care must be taken to ensure a tight seal to prevent leakage. This device is only suitable for sealing the valve end; the sealing effect at the end being used can be selected by the user according to the actual situation, which will not be elaborated here.) After the sealing pipe 230 is connected, the user can then clamp the end of the sealing pipe 230 away from the equipment into the sealing ring 200 of the pipe fitting 120. After the sealing ring 240 and the sealing ring 200 are clamped together, the outer surfaces of the sealing ring 200 and the sealing ring 240 are then... The inner surfaces of connecting ring 210 and connecting ring 250 abut against each other, and then connecting ring 210 and connecting ring 250 are fixed with bolts. Since sealing ring 200 and sealing ring 240, together with rubber gasket, form the first sealing effect, and the connection between the outer surfaces of sealing ring 200 and sealing ring 240, through connecting ring 210 and connecting ring 250, forms the second sealing effect, thus achieving a double sealing effect. Since sealing element 1 and sealing element 2 are interlocked and connected to form a double sealing structure, the possibility of fluid leakage is greatly reduced, leakage is effectively prevented, and the system is guaranteed to be stable and operating normally.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
