Description

Technical Field

[0001] The utility model belongs to the technical field of valve disassembly, and particularly relates to a clamp-type valve disassembly tool. Background Art

[0002] According to pipeline process standards, industrial control valves have three common connection methods, namely wafer type, flange type and threaded type. Among them, the wafer type is common in centerline wafer butterfly valves and check valves. The wafer type clamps the valve body through two flanges, that is, the valve body is fixed to the pipeline through the clamping force of the two flanges. The wafer valve body has a simple structure, small size and light weight. Compared with other connection methods, the wafer valve body is usually more compact and occupies less installation space, so it is often used in production and life.

[0003] However, since the flanges on both sides of the wafer-type valve body need to ensure the tightness of both ends of the valve body, the flanges will exert a greater clamping force on the valve body. When removing the valve body, it is necessary to use tools such as crowbars to assist in removal, which makes removal difficult. When the installation position is limited, the work efficiency of removing the valve will be greatly reduced. Utility Model Content

The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantially changing the technical content.

[0023] In order to describe the utility model in detail, a wafer-type valve disassembly tool of the utility model is specifically described below:

[0024] Please combine Figure 1 and Figure 2 As shown, the utility model provides a wafer-type valve disassembly tool, comprising a rotating seat 4 and a holding rod 2, wherein the rotating seat 4 has mounting ends opposite to each other along a first direction; two holding rods 2 are respectively arranged at the mounting ends along the first direction, and at least one holding rod 2 is threadedly connected to the rotating seat 4, and the first direction is the axial direction of the holding rod 2. By respectively connecting the holding rods 2 to the mounting ends of the rotating seat 4, and at least one holding rod 2 is threadedly connected to the rotating seat 4, when the rotating seat 4 rotates along the circumferential direction of the holding rod 2, the holding rod 2 threadedly connected to the rotating seat 4 will extend or shorten, so as to separate the two flanges and disassemble the valve when the wafer-type valve is disassembled.

[0025] Among them, one supporting rod 2 is connected to the rotating seat 4 in the axial direction, and the other supporting rod 2 is threadedly connected to the rotating seat 4. In some embodiments, the supporting rod 2 connected to the rotating seat 4 in the axial direction has a protrusion 1 arranged along the circumference of the supporting rod 2 at the connection with the rotating seat 4, and the corresponding mounting end of the rotating seat 4 is provided with a mounting hole, and the mounting hole has a rotating groove that cooperates with the above-mentioned protrusion 1, and the protrusion 1 is accommodated in the rotating groove. When the rotating seat 4 rotates, the protrusion 1 rotates in the rotating groove, avoiding the friction between the supporting rod 2 and the flange due to the fixed connection between the supporting rod 2 and the rotating seat 4, which is easy to damage the flange. The other supporting rod 2 is threadedly connected to the rotating seat 4, which can make the length of the clamp-type valve disassembly tool along the axial direction of the supporting rod 2 longer or shorter.

[0026] The two abutting rods 2 are both threadedly connected to the rotating seat 4, and the thread directions of the two abutting rods 2 are opposite. The two abutting rods 2 are both threadedly connected to the rotating seat 4, which can make the length of the wafer-type valve disassembly tool along the axial direction of the abutting rods 2 longer and shorter more quickly, thereby improving the efficiency of scaling the length of the wafer-type valve.

[0027] In detail, threaded holes are provided at the mounting ends, and the threads of the two threaded holes correspond to the threads of the corresponding supporting rods 2. By providing threaded holes at the mounting ends, the structure is simple and easy to produce and manufacture. In some embodiments, the connecting end of the supporting rod 2 and the rotating seat 4 has a threaded hole, and the mounting end has an external thread corresponding to the above-mentioned threaded hole. The mounting end is inserted into the threaded hole to achieve the connection between the supporting rod 2 and the rotating seat 4.

[0028] The rotating seat 4 has a force-bearing surface 5 opposite to the second direction, and the second direction is perpendicular to the first direction. By providing the force-bearing surface 5 on the rotating seat 4, a wrench can be used to rotate the rotating seat 4 around the axial direction of the abutting rod 2. In some embodiments, the rotating seat 4 is provided with a plurality of sleeves at intervals along the circumference of the abutting rod 2, and the rotating seat 4 can be rotated around the axial direction of the abutting rod 2 by using a rotating rod corresponding to the above-mentioned sleeves.

[0029] The rotating seat 4 is cylindrical, the axial direction of the rotating seat 4 extends along the first direction, and the rotating seat 4 has six force-bearing surfaces 5 connected in sequence along the circumference of the rotating seat 4, and the six force-bearing surfaces 5 are opposite to each other. By providing six force-bearing surfaces 5, it is convenient for the operator to select different rotating surfaces for operation when rotating the rotating seat 4.

[0030] In detail, the six force-bearing surfaces 5 are located in the middle of the rotating seat 4 along the axial direction of the rotating seat 4. The six force-bearing surfaces 5 arranged in the middle of the rotating seat 4 enable the operator to keep the same distance from the two flanges when rotating the rotating seat 4, so as to avoid the flanges hindering the operator's operation.

[0031] Among them, locking nuts 3 are arranged between the two abutting rods 2 and the rotating seat 4. By arranging the locking nuts 3, after the two flanges of the wafer-type valve are spread apart, the relative positions between the two abutting rods 2 and the rotating seat 4 can be locked by the locking nuts 3, so as to avoid the influence of the relative position change between the two abutting rods 2 and the rotating seat 4 on the operator to disassemble and assemble the valve, thereby reducing the working efficiency.

[0032] Among them, one end of the abutting rod 2 is connected to the rotating seat 4, and the other end of the abutting rod 2 is provided with a protrusion 1 around the axial direction of the abutting rod 2. The protrusion 1 is provided at the part where the abutting rod 2 contacts the flange, which can increase the contact area between the end of the abutting rod 2 and the flange, thereby ensuring the abutting effect of the abutting rod 2 on the flange, and preventing the relative position between the abutting rod 2 and the flange from changing during the rotation of the rotating seat 4 around the axial direction of the abutting rod 2, thereby affecting the use effect of the clamp-type valve removal tool.

[0033] When using the wafer-type valve disassembly tool to disassemble the valve, first remove the connecting bolts between the valve and the flange, then use a wrench or directly turn the rotating seat 4 by hand, adjust the wafer-type valve disassembly tool to a suitable length, and place it between the two flanges, with each supporting rod 2 corresponding to one flange. When the rotating seat 4 is turned by hand or with a wrench through the force surface 5, the bolts on both sides will extend to both sides at the same time, stretching the two flanges and the pipes connected to the flanges, increasing the distance between the flanges, and the valve can be removed. Similarly, when the valve needs to be reinstalled, first put the valve in the installation position, then turn the rotating seat 4 with a wrench to shrink the length of the wafer-type valve, so that the valve is clamped by the two flanges, and finally use bolts to connect and tighten the valve and the flange.

[0034] To summarize, by connecting the supporting rods 2 to the mounting ends of the rotating seat 4 respectively, and at least one supporting rod 2 is threadedly connected to the rotating seat 4, when the rotating seat 4 rotates along the circumferential direction of the supporting rods 2, the supporting rods 2 threadedly connected to the rotating seat 4 will extend or shorten, so as to separate the two flanges and disassemble the valve when the clamp-type valve is disassembled.

[0035] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
