Description

Technical Field

[0001] This utility model relates to the field of valve detection technology, and specifically to a valve detection device with adaptive valve position. Background Technology

[0002] Valves are control components in fluid transport systems, with functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief. Valves require sealing performance testing after production.

[0003] Currently, the following method is commonly used when testing the air tightness or water pressure of valves: the valve is placed on the valve seat of the testing equipment, and the valve body is fixed by the clamping mechanism on the valve seat; at the same time, a conical sealing clamp with a sealing ring on the testing equipment is inserted into and pressed against the valve interface to form a closed cavity for pressure testing.

[0004] However, the aforementioned detection method has a significant drawback: the valve is repeatedly positioned and excessively constrained in space. Specifically, the valve is first rigidly fixed in a preset position by the valve seat and its clamping mechanism. Subsequently, the operator needs to precisely align and insert the sealing clamp into the other port of the valve. Due to manufacturing tolerances in the valve itself and its port, and mechanical errors in the positioning of the valve seat clamping mechanism, in actual operation, it is difficult to perfectly align the central axis of the valve port with the central axis of the sealing clamp.

[0005] This misalignment problem can lead to a series of adverse consequences: 1. Poor sealing effect; the conical seal clamp may only contact one side of the valve interface, resulting in uneven force on the sealing ring, which cannot form an effective seal, thus causing media leakage and affecting the accuracy of the test results.

[0006] 2. Component damage: During forced insertion or tightening, the eccentric interaction force can easily scratch the inner wall of the valve interface or damage the sealing ring on the sealing clamp, shortening its service life.

[0007] 3. Low operating efficiency; operators need to repeatedly adjust the position of the valve or the angle of the sealing clamp, which is time-consuming and labor-intensive, reducing the testing efficiency. Utility Model Content

[0008] 1. The problem to be solved To address the problems of repeated positioning and excessive constraint of valves in space in existing technologies, this invention provides a valve detection device with adaptive valve position, which enables the valve to adaptively adjust its position in space.

[0009] 2. Technical Solution To solve the above problems, the technical solution adopted by this utility model is as follows: A valve detection device with adaptive valve position, comprising: A sealing clamp is used to insert into and press against the valve port to form a closed cavity for pressure testing; A valve mounting seat is used to place a valve. When the valve is placed on the valve mounting seat, there is an adjustment clearance on all sides of the valve except for the bottom surface. A buffer pad is placed between the bottom surface of the valve and the valve seat when the valve is placed on the valve seat, so that the position of the valve can be adaptively adjusted downward when the valve interface is inserted by the sealing clamp.

[0010] As a preferred embodiment of this utility model, the valve mounting seat includes an inner mounting box, and there is an adjustable gap between the inner side wall of the inner mounting box and the valve disposed therein.

[0011] As a preferred embodiment of this utility model, the inner mounting box is provided with multiple notches for inserting sealing clamps, and the positions of the multiple notches are respectively adapted to the positions of multiple valve interfaces on the valve.

[0012] As a preferred embodiment of this utility model, a buffer pad is disposed at the bottom of the inner mounting box, and the thickness of the buffer pad is less than half the height of the inner mounting box.

[0013] As a preferred embodiment of this utility model, the upper end of the inner mounting box is open, so that when the valve interface is inserted by the sealing clamp, the position of the valve can be adaptively adjusted upward.

[0014] As a preferred embodiment of the present invention, the sealing clamp includes a thin metal connector for inserting into and pressing the valve interface, the thin metal connector being deformable to form a closed cavity with the valve interface.

[0015] As a preferred embodiment of this utility model, the sealing clamp further includes a fluid injection component, which has a fluid channel for injecting fluid into the valve. A connector mounting position is provided at the outlet of the fluid channel. A thin metal connector is installed at the connector mounting position, and a fluid through hole adapted to the fluid channel is provided on the thin metal connector.

[0016] As a preferred embodiment of this utility model, the metal thin-layer connector includes a large-diameter end and a small-diameter end, with the diameter gradually increasing from the small-diameter end to the large-diameter end. When the valve interface is sealed, the small-diameter end is located inside the valve interface, and the large-diameter end is located outside the valve interface. The connector mounting position can fit against the inner wall surface of the thin metal connector, providing support for the thin metal connector.

[0017] As a preferred embodiment of this utility model, the fluid injection component includes a main body and a clamping head. The clamping head is detachably mounted on the main body, and a sealing element is provided between the clamping head and the main body. The connector mounting position is provided on the clamping head. The fluid passage passes through the main body and the clamping head, with the inlet of the fluid passage located on the main body and the outlet located on the clamping head.

[0018] As a preferred embodiment of this utility model, it also includes a connector fixing seat connected to the fluid injection component, the connector fixing seat being used to fix the metal thin-layer connector cap to the connector mounting position.

[0019] 3. Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: (1) This utility model enables the valve to move in any direction after being placed on the valve fixing seat by cooperating with the valve fixing seat and the buffer pad. If there is a deviation between the central axis of the valve interface and the central axis of the sealing clamp, the conical end of the sealing clamp will come into contact with the valve interface during the process of the sealing clamp being inserted and pressed against the valve interface, causing the valve to have a displacement tendency to move to the correct position, so as to correct the deviation.

[0020] (2) This utility model seals the valve interface through a thin metal joint. When the thin metal joint is inserted into and pressed against the valve interface, the part of the thin metal joint that contacts the valve interface is squeezed and deformed, completely sealing the contact part between the valve interface and the thin metal joint. Furthermore, since the sealing component is made of metal, a hard contact seal is formed. When the valve is subjected to high pressure testing, the thin metal joint is not easily squeezed and deformed by the high pressure fluid, thus improving the reliability of the seal.

[0023] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of the invention, should still fall within the scope of the technical content disclosed herein. Furthermore, terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity and not intended to limit the scope of implementation.

[0025] Example 1 like Figure 1 , Figure 4 and Figure 5 As shown, this embodiment provides a valve detection device with adaptive valve position, including: A sealing clamp 100 is mounted on a cylinder and can be pushed by the cylinder to insert into and press against the valve port 410 to form a closed cavity for easy pressure testing. The end of the sealing clamp 100 used to insert into and press against the valve port 410 includes a large-diameter end and a small-diameter end, with the diameter gradually increasing from the small-diameter end to the large-diameter end. When the valve port 410 is sealed, the small-diameter end is located inside the valve port 410, and the large-diameter end is located outside the valve port 410. This end is preferably conical.

[0026] If there is a deviation between the central axis of the valve port 410 and the central axis of the sealing clamp 100, the tapered end of the sealing clamp 100 will abut against the valve port 410 during the insertion and clamping process of the sealing clamp 100, causing the valve 400 to tend to move towards the correct position. This correct position refers to the position where the central axis of the valve port 410 coincides with the central axis of the sealing clamp 100. For example, if the central axis of the valve port 410 is offset to the left relative to the central axis of the sealing clamp 100, the valve 400 will tend to move to the right during the insertion and clamping process of the sealing clamp 100. If the central axis of the valve port 410 is offset upward relative to the central axis of the sealing clamp 100, the valve 400 will tend to move downward during the insertion and clamping process of the sealing clamp 100.

[0027] Valve mounting seat 200. The valve mounting seat 200 is used to hold the valve 400. When the valve 400 is placed on the valve mounting seat 200, there are adjustment clearances 210 on all sides of the valve 400 except for its bottom surface. That is, there are adjustment clearances 210 on the top, left, right, front, and rear sides, allowing the valve 400 to move freely upwards and in any direction within the horizontal plane, providing a basis for the self-adjusting position of the valve 400. This horizontal plane refers to the mounting plane of the valve mounting seat 200 and the cylinder.

[0028] Buffer pad 300. When valve 400 is placed on valve seat 200, buffer pad 300 is disposed between the bottom surface of valve 400 and valve seat 200. Buffer pad 300 can be compressed, allowing valve 400 to move downward freely, providing a basis for the self-adjustment of valve 400.

[0029] In this embodiment, the valve 400, after being placed on the valve fixing seat 200, can move in any direction by cooperating with the buffer pad 300. If there is a deviation between the central axis of the valve interface 410 and the central axis of the sealing clamp 100, the tapered end of the sealing clamp 100 will abut against the valve interface 410 during the process of the sealing clamp 100 being inserted into and pressing the valve interface 410, causing the valve 400 to have a displacement tendency to move to the correct position, so as to correct the deviation.

[0030] In one embodiment, the valve mounting base 200 includes an inner mounting box 220. An adjustment gap 210 exists between the inner wall of the inner mounting box 220 and the valve 400 disposed therein, allowing the valve 400 to move in any direction within the horizontal plane. This enables the valve 400 to adaptively adjust its position horizontally when the valve port 410 is inserted by the sealing clamp 100. The upper end of the inner mounting box 220 is open, allowing the valve 400 to adaptively adjust its position upwards when the valve port 410 is inserted by the sealing clamp 100. A buffer pad 300 is disposed at the bottom of the inner mounting box 220, allowing the valve 400 to adaptively adjust its position downwards when the valve port 410 is inserted by the sealing clamp 100.

[0031] Preferably, the thickness of the buffer pad 300 is less than half the height of the inner mounting box 220, so that the valve 400 has sufficient space to move upward on the inner mounting box 220, and prevents the valve 400 from detaching from the inner mounting box 220 during the upward movement.

[0032] Preferably, the inner mounting box 220 is provided with multiple notches 230 for the insertion of the sealing clamp 100, and the positions of the multiple notches 230 are respectively adapted to the positions of multiple valve interfaces 410 on the valve 400. For example, when the valve 400 to be tested is a three-way valve 400, the inner mounting box 220 is provided with three notches 230.

[0033] Example 2 like Figure 2 and Figure 3 As shown, based on Embodiment 1, this embodiment provides a sealing clamp 100, including a thin metal connector 110 for inserting into and pressing against the valve interface 410. When the thin metal connector 110 is inserted into and presses against the valve interface 410, a large interaction force is generated between the thin metal connector 110 and the valve interface 410. This interaction force is sufficient to deform the contact area between the thin metal connector 110 and the valve interface 410, completely sealing the contact area between the valve interface 410 and the thin metal connector 110. At this time, fluid can be injected into the valve 400 to test the tightness of the valve 400. Furthermore, since the sealing component is made of metal, a hard contact seal is formed. When the valve 400 is subjected to high pressure testing, the thin metal connector 110 is not easily deformed by the high-pressure fluid, improving the reliability of the seal.

[0034] Preferably, the thin metal connector 110 is made of a soft metal, such as brass.

[0035] In one embodiment, the sealing clamp 100 further includes a fluid injection member 120, which has a fluid channel 130 for injecting fluid into the valve 400. After the sealing clamp 100 is inserted into and presses against the valve port 410, fluid can be injected into the valve 400 through the fluid channel 130 to test the sealing performance of the valve 400. A connector mounting position 140 is provided at the outlet of the fluid channel 130, and a thin metal connector 110 is mounted on the connector mounting position 140. The thin metal connector 110 has a fluid through hole 150 adapted to the fluid channel 130, and the fluid sequentially passes through the fluid channel 130 and the fluid through hole 150 into the valve port 410.

[0036] Preferably, the connector mounting position 140 can fit against the inner wall surface of the thin metal connector 110, providing support for the thin metal connector 110. For example, when the thin metal connector 110 is configured as a conical shell, the connector mounting position 140 is configured as a conical surface adapted to the conical shell, providing stable support for the conical shell. When the conical shell presses against the valve interface 410, only the outer wall surface of the conical shell deforms, sealing the valve interface 410 and preventing large-area deformation of the conical shell.

[0037] In one embodiment, the fluid injection component 120 further includes a main body 121 and a clamping head 122. The clamping head 122 is detachably mounted on the main body 121, and a seal 123 is provided between the clamping head 122 and the main body 121. A connector mounting position 140 is provided on the clamping head 122. A fluid channel 130 passes through the main body 121 and the clamping head 122, and the inlet of the fluid channel 130 is provided on the main body 121, and the outlet is provided on the clamping head 122. After the sealing valve 400 is clamped and sealed multiple times, the connector mounting position 140, which is a component that fits tightly with the thin metal connector 110, may deform. If the connector mounting position 140 deforms after being set on the clamping head 122, only the clamping head 122 needs to be replaced.

[0038] Optionally, the clamping head 122 is threaded onto the main body 121, and the seal 123 can be configured as a sealing copper gasket.

[0039] In one embodiment, the fluid injection component 120 further includes a connector fixing seat 160 connected to the fluid injection component 120. The connector fixing seat 160 is used to fix the metal thin-film connector 110 gland onto the connector mounting position 140. Since the metal thin-film connector 110 is a metal sealing element 123, it lacks elasticity and relies on deformation to achieve a seal. By making the metal thin-film connector 110 detachable, it is convenient to replace the metal thin-film connector 110 after the valve 400 sealing test is completed.

[0040] Specifically, one end of the connector fixing seat 160 is provided with an internal thread, and the clamping head 122 of the fluid injection component 120 is provided with an external thread adapted to the internal thread. After the connector fixing seat 160 is installed and fixed on the clamping head 122, the thin metal connector 110 is clamped and fixed between the connector fixing seat 160 and the connector mounting position 140. The connector fixing seat 160 should be far away from the fluid through hole 150 on the thin metal connector 110 to avoid interfering with the clamping action of the thin metal connector 110 at the valve interface 410. When the thin metal connector 110 is set as a cylindrical shell, the connector fixing seat 160 is also correspondingly set as an annular shell so that the connector fixing seat 160 can clamp and fix the thin metal connector 110 in a form that fits against the outer wall surface of the thin metal connector 110.

[0041] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
