Description

Technical Field

[0001] The implementation mode of the utility model relates to the field of manufacturing intelligent pressure-regulating butterfly valves. More specifically, the utility model relates to an assembly tool for intelligent pressure-regulating butterfly valves. Background Art

[0002] Intelligent pressure regulating butterfly valves are widely used in the semiconductor industry. They can be used in the preparation of semiconductor materials, wafer processing, photolithography, thin film deposition and other links. Intelligent pressure regulating butterfly valves for semiconductor equipment can achieve precise control of gas and liquid to ensure the stability and precision requirements of semiconductor products. The intelligent pressure regulating butterfly valve includes a controller, a drive mechanism, a valve body, a valve stem passing through the valve body, and a valve plate arranged in the valve body and connected to the valve stem. The controller controls the drive mechanism to move to drive the valve stem connected to the drive mechanism to rotate, and drives the valve plate connected to the valve stem to rotate accordingly, so as to achieve precise control of the flow rate and on-off of the gas and liquid passing through the intelligent pressure regulating butterfly valve. The intelligent pressure regulating butterfly valve also includes a sealing ring, a spring, a gasket and an elastic retaining ring. When assembling the intelligent pressure regulating butterfly valve, the sealing ring, spring, gasket and elastic retaining ring used for sealing between the valve stem and the mounting hole of the valve body must be installed in the mounting hole first, and then the valve stem must be passed through the elastic retaining ring, gasket, spring and sealing ring in the mounting hole in sequence. This ensures that when the valve plate is in motion, the gas and fluid passing through the valve body will not leak out from between the mounting hole and the valve stem.

[0003] The specific installation process of the sealing ring, spring, gasket and elastic retaining ring is as follows: the operator is required to install the sealing ring, spring and gasket into the mounting hole of the valve body of the intelligent pressure-regulating butterfly valve in sequence, and then apply pressure to the gasket so that the gasket compresses the spring and the sealing ring and exposes the slot in the mounting hole, and finally installs the elastic retaining ring into the slot to prevent the sealing ring, spring and gasket from detaching from the mounting hole. However, since the aperture of the mounting hole is usually small, although the operator can apply pressure to the gasket to shrink the sealing ring and spring and expose the slot in the mounting hole. However, since the slot is located on the hole wall of the mounting hole, the operator cannot install the elastic retaining ring into the slot while continuously applying pressure to the gasket, thereby failing to complete the assembly of the intelligent pressure-regulating butterfly valve.

[0027] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0028] Figure 1 The figure shows an assembly tool for the intelligent pressure regulating butterfly valve provided in this embodiment. Figure 2 Shows Figure 1 A partial enlarged view of the A in the figure. Figure 1 and Figure 2 As shown, when assembling the intelligent pressure-regulating butterfly valve, the sealing ring 300, the spring 200, the gasket 100 and the elastic retaining ring 500 need to be installed in the mounting hole 401 of the valve body 400, and the spring 200 and the sealing ring 300 need to be compressed before the elastic retaining ring 500 can be installed in the slot of the mounting hole 401. Since the space of the mounting hole 401 is too narrow, it is difficult for the operator to compress the spring 200 with bare hands or using existing tools, which makes the process of assembling the intelligent pressure-regulating butterfly valve particularly difficult.

[0029] Embodiment 1

[0030] This embodiment provides an assembly tool for an intelligent pressure regulating butterfly valve to solve the above problems. Figure 1 and Figure 2 The assembly tool includes a connecting rod 1, a pressing member 2 and a driving member 3. The connecting rod 1 is used to pass through the mounting hole 401 of the valve body 400 of the intelligent pressure regulating butterfly valve, and force the sealing ring 300, the spring 200 and the gasket 100 of the intelligent pressure regulating butterfly valve and pre-installed in the mounting hole 401 to be sleeved outside the connecting rod 1; the pressing member 2 is arranged on one end of the connecting rod 1 and is used to abut against the gasket 100; the driving member 3 is arranged outside the valve body 400 and connected to the other end of the connecting rod 1, wherein the driving member Component 3 can pull the pressing component 2 to move in the mounting hole 401 through the connecting rod 1, and force the pressing component 2 to compress the spring 200 and the sealing ring 300 through the gasket 100 until the pressing component 2 exposes the groove of the elastic retaining ring 500 provided in the mounting hole 401 and used to install the intelligent pressure-regulating butterfly valve, so that the elastic retaining ring 500 can be smoothly installed in the groove of the mounting hole 401 and prevent the sealing ring 300, the spring 200 and the gasket 100 from detaching from the mounting hole 401.

[0031] By using the assembly tool provided above, when the sealing ring 300, the spring 200 and the gasket 100 are pre-installed into the mounting hole 401 of the valve body 400, the gasket 100 can be pressed to cause the gasket 100 to move in the mounting hole 401 and compress the spring 200 and the sealing ring 300 until the slot in the mounting hole 401 for installing the circlip 500 is exposed. At this time, the operator can smoothly install the circlip 500 into the slot of the mounting hole 401 and prevent the sealing ring 300, the spring 200 and the gasket 100 from being separated from the mounting hole 401. In other words, the assembly tool can assist the operator to quickly and easily install the sealing ring 300, the spring 200, the gasket 100 and the circlip 500 into the mounting hole 401 of the valve body 400.

[0032] like Figure 1 and Figure 2 As shown, in order to ensure that the driving member 3 can drive the connecting rod 1 smoothly, an external thread may be provided on the end of the connecting rod 1, and the driving member 3 may include an internal thread that matches the external thread. Through the thread matching of the external thread and the internal thread, the operator can drive the connecting rod 1 to move in the mounting hole 401 by screwing the driving member 3, and the thread matching method is simple in manufacturing process and low in cost, which is conducive to reducing the manufacturing cost of the assembly tool.

[0033] Preferably, a weight-reducing hole may be provided on the driving member 3 to reduce the weight of the driving member 3 , thereby facilitating manual operation by an operator and preventing the driving member 3 from being too heavy, which would increase the difficulty of installation.

[0034] Preferably, the driving member 3 includes a side that can abut against the inner wall of the valve body 400 and is set to a spherical surface, so that the driving member 3 can make approximately linear contact with the inner wall of the valve body 400. On the one hand, the contact area between the driving member 3 and the valve body 400 can be reduced to prevent damage to the inner surface of the valve body. On the other hand, since the contact area is reduced, the friction resistance is also reduced, so that the operator can more easily screw the driving member 3.

[0035] Preferably, an anti-skid structure 31 (not shown) is provided on the outer surface of the driving member 3. The anti-skid structure 31 can be a rubber pad, an embossed structure or a frosted coating provided along the circumference of the driving member 3, or a prism shape. The anti-skid structure 31 increases the friction force when the operator contacts the outer surface of the driving member 3, thereby facilitating the operator to screw the driving member 3.

[0036] It should be noted that the present embodiment does not specifically limit the specific structure of the driving member 3 , and any structure that can drive the connecting rod 1 to move axially in the mounting hole 401 should be within the protection scope of the present disclosed embodiment.

[0037] In this embodiment, Figure 3FIG. 2 shows a top view of an assembly tool for an intelligent pressure regulating butterfly valve provided in this embodiment. Figure 4 Shows Figure 3 A partial enlarged view of point B in the figure. Figure 4 and Figure 3 Combined with Figure 1 and Figure 2 As shown, the clamping member 2 may be optionally a gasket structure, and a clearance notch is provided thereon for avoiding the perforated end of the circlip 500. After the sealing ring 300, the spring 200, the washer 100 and the circlip 500 are sequentially installed in the mounting hole 401, the assembly tool needs to be removed from the valve body 400. In this process, the difference between the inner and outer diameters of the clamping member 2 should be kept within a reasonable range to ensure that it can be smoothly removed from the mounting hole 401. If the clamping member 2 is designed with a clearance notch, the difference between the inner and outer diameters can be appropriately increased. Such a design can enhance the stability and reliability of the clamping member 2 when pushing the washer 100 without affecting the overall assembly.

[0038] In this embodiment, if Figure 4 and Figure 3 Combined with Figure 1 and Figure 2 As shown, the pressing member 2 is detachably connected to the connecting rod 1. The pressing member 2 can be replaced by the detachable connection so that it is suitable for being installed in the mounting holes 401 of different sizes.

[0039] Preferably, the assembly tool also includes a screw 4, which is threadedly connected to the connecting rod 1, and the clamping piece 2 is arranged between the screw 4 and the connecting rod 1. The threaded connection can not only realize the detachable connection between the clamping piece 2 and the connecting rod 1, but also ensure that the clamping piece 2 and the connecting rod 1 are firmly connected.

[0040] In this embodiment, if Figure 4 and Figure 3 Combined with Figure 1 and Figure 2 As shown, the assembly tool is made of resin or metal material. When the assembly tool is made of metal material, by utilizing the high strength and toughness of the metal material, the assembly tool can withstand a large load without deformation or breakage, thereby ensuring the durability and stability of the tool. When the assembly tool is made of resin material, since the density of the resin material is lower than that of the metal material, the weight of the assembly tool can be reduced, making the assembly tool lighter, but this is only applicable to small intelligent pressure regulating butterfly valves.

[0041] Embodiment 2

[0042] The second embodiment also provides an assembly tool for an intelligent pressure-regulating butterfly valve. The assembly tool provided in the second embodiment is basically the same as that in the first embodiment, and the difference is mainly described below. In order to save space, the similarities between the first and second embodiments will not be repeated.

[0043] Figure 3 FIG. 1 is a schematic diagram showing the structure of an assembly tool for an intelligent pressure regulating butterfly valve provided in this embodiment. Figure 3 Combined with Figure 1 and Figure 2 As shown, in the present embodiment, two mounting holes 401 are symmetrically arranged along the diameter direction of the valve body 400, the number of connecting rods 1 and the number of clamping members 2 are both two, one connecting rod 1 is provided with a clamping member 2 and is inserted into one mounting hole 401, and the other connecting rod 1 is provided with another clamping member 2 and is inserted into the other mounting hole 401, one end of the driving member 3 is provided with a first internal thread that cooperates with the external thread of one connecting rod 1, and the other end of the driving member 3 is provided with a second internal thread that cooperates with the external thread of the other connecting rod 1, and the spiral directions of the first internal thread and the second internal thread are opposite.

[0044] In this way, the operator can simultaneously drive the two connecting rods 1 and the two pressing members 2 by simply rotating the driving member 3, so that the two washers 100 can move in the corresponding mounting holes 401 and compress the corresponding springs 200 and sealing rings 300 until the slots for mounting the circlips 500 in the two mounting holes 401 are simultaneously exposed. This method is conducive to further reducing the installation difficulty of the intelligent pressure regulating butterfly valve and once again improving the installation efficiency of the intelligent pressure regulating butterfly valve.

[0045] In the above description of the present application, unless otherwise clearly specified and limited, the terms "fixed", "installed", "connected" or "connected" and the like should be understood in a broad sense. For example, with regard to the term "connection", it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements. Therefore, unless otherwise clearly defined in the present application, those skilled in the art can understand the specific meanings of the above terms in the present utility model according to the specific circumstances.

[0046] According to the above description of the present application, those skilled in the art may also understand that the terms used below, such as "axial", "radial" and other terms indicating orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings of the present application, and are only for the purpose of facilitating the explanation of the scheme of the present utility model and simplifying the description, rather than explicitly or implicitly indicating that the device or element involved must have the specific orientation, be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms cannot be understood or interpreted as limitations on the scheme of the present utility model.

[0047] In addition, the terms "first" or "second" used in this application to refer to numbers or ordinals are only used for descriptive purposes and cannot be understood as explicitly or implicitly indicating relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this application, the meaning of "plurality" is at least two, such as two, three or more, etc., unless otherwise clearly and specifically defined.
