Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure valves, in particular to a highly sealed detachable high-pressure valve. Background Art

[0002] High-pressure valves have been widely used in the fields of superhard material manufacturing, chemical industry, petrochemical industry, hydrostatic treatment such as processing technology, ultra-high hydrostatic extrusion, powder metallurgy, metal forming, and geophysical and geological research. They can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil products, liquid metals, and radioactive media. The closing member is a disc-shaped valve plate that rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjusting.

[0003] Some existing high-pressure valves are composed of multiple components such as two valve body pipes, a valve ball, and a handle connected to each other. The valve ball is located between the two valve body pipes, and the two valve body pipes are fixed by bolts and nuts. When assembling large high-pressure valves, due to the large volume and heavy weight of the two valve pipes, it is difficult to align the screw holes at the connection ends of the two valve pipes. It is necessary to move the valve body pipes multiple times for calibration before the bolts can be inserted between the two valve body pipes. However, during the alignment process by workers, it is not only time-consuming and laborious, but also easy to cause friction and wear to the connection ends of the two valve body pipes, thereby reducing the sealing performance of the high-pressure valve. Therefore, a highly sealed detachable high-pressure valve is proposed. Summary of the Utility Model

[0027] Embodiment

[0028] Referring to Figure 1 - Figure 5 , which is an embodiment of the present utility model, provides a highly sealed detachable high-pressure valve, including: a valve body unit 100 and a disassembly and assembly unit 200;

[0029] Wherein, the valve body unit 100 includes a first valve body 101 and a second valve body 102. The first valve body 101 and the second valve body 102 are fixedly connected by a plurality of bolts and nuts. A valve ball 103 is slidably arranged on the inner walls of the first valve body 101 and the second valve body 102 together. Circular grooves 104 are formed at the opposite ends of the first valve body 101 and the second valve body 102. The first valve body 101 and the second valve body 102 are both slidably connected with a rubber sleeve 105 through the circular grooves 104;

[0030] The disassembly and assembly unit 200 includes two insertion rods 201 fixedly connected to one side of the second valve body 102. The ends of the two insertion rods 201 penetrate through the first valve body 101 and are provided with rectangular grooves. The inner wall of the rectangular groove is rotatably connected with a limiting block 202. One side of the limiting block 202 is fixedly connected with a torsion spring 203. The end of the torsion spring 203 far from the first valve body 101 is fixedly connected to the inner wall of the rectangular groove. The bottom of the limiting block 202 is fixedly connected with a connecting rope 204 penetrating through the insertion rod 201. The end of the connecting rope 204 is fixedly connected with a pull ring 205. A rotating rod 206 slidably penetrates through the top of the first valve body 101. The bottom end of the rotating rod 206 is slidably inserted onto the valve ball 103. A handle 207 is slidably arranged on the outer side of the rotating rod 206. The top of the rotating rod 206 is threadedly connected with a hexagon bolt. The hexagon bolt penetrates through the rotating rod 206 and is threadedly connected with the valve ball 103. A straight rod 208 is fixedly connected between the two pull rings 205. A clamping block 209 corresponding to the position of the straight rod 208 is fixedly connected to the side surface of the second valve body 102. Two through holes fitting the straight rod 208 are opened on the clamping block 209.

[0031] The high-pressure valve body is fixedly connected and composed of the first valve body 101 and the second valve body 102. A rectangular block is fixedly connected to the inner wall of the handle 207. A sliding groove fitting the rectangular block is opened on one side of the rotating rod 206. The handle 207 is fixed on the rotating rod 206 through a hexagon bolt. By rotating the handle 207, the rotating rod 206 can be driven to rotate. The bottom of the rotating rod 206 is square-shaped. A square groove fitting the bottom of the rotating rod 206 is opened on the upper surface of the valve ball 103. By rotating the rotating rod 206, the steering of the valve ball 103 can be controlled, so that the opening and closing of the high-pressure valve body can be controlled. By rotating the hexagon bolt, the handle 207, the rotating rod 206 and the valve ball 103 can be disassembled and separated in sequence to facilitate maintenance;

[0032] When connecting the first valve body 101 and the second valve body 102, two positioning holes fitting the insertion rods 201 are opened at the connection end of the first valve body 101. The end of the insertion rod 201 facing the first valve body 101 is tapered to facilitate inserting the insertion rod 201 into the positioning hole. When the insertion rod 201 is inserted into the positioning hole, the limiting block 202 is squeezed into the rectangular groove of the insertion rod 201 by the positioning hole. When the insertion rod 201 is no longer in contact with the positioning hole, the torsion spring 203 drives the end of the limiting block 202 facing the second valve body 102 to deflect upward. Thus, the limiting block 202 can limit the first valve body 101, making the second valve body 102 tightly fit the first valve body 101, and the bolt holes of the second valve body 102 and the first valve body 101 are accurately aligned to facilitate installing bolts and nuts;

[0033] At this time, the circular grooves 104 of the second valve body 102 and the first valve body 101 are also aligned with each other, so that the two ends of the rubber sleeve 105 are respectively located in the two circular grooves 104 to ensure the sealing of the connection between the second valve body 102 and the first valve body 101. The two through holes of the limit block 202 are used to limit the position of the straight rod 208. The limit block 202 and the straight rod 208 are used to prevent the pull ring 205 from being pulled. When disassembly is required, the straight rod 208 is pulled to separate it from the through hole of the limit block 202 close to the position of the first valve body 101. Then, the two pull rings 205 pull the two limit blocks 202 synchronously downward to the rectangular grooves of the two plug rods 201 through the connecting rope 204, and then the straight rod 208 is moved to the other through hole of the limit block 202, thereby enabling the limit block 202 to always be located in the rectangular groove of the plug rod 201, and the restriction on the first valve body 101 is released for disassembly and separation.

[0034] In addition, a sealing ring 210 is slidably sleeved on the rod surface of the rotating rod 206 , and a circular sliding groove fitting the sealing ring 210 is opened on the inner wall of the first valve body 101 .

[0035] The sealing ring 210 can ensure the sealing between the plug rod 201 and the first valve body 101. When the first valve body 101 and the second valve body 102 are disassembled and separated from each other, the hexagonal bolt is removed from the plug rod 201, and the plug rod 201 is lifted upward so that it no longer contacts the valve ball 103. Then the valve ball 103 can be separated from the plug rod 201, and the plug rod 201 can be slid out of the inner cavity of the first valve body 101 to facilitate the replacement of the sealing ring 210, thereby ensuring the overall sealing.

[0036] Furthermore, the top of the first valve body 101 is opened and closed with an arc-shaped two-way arrow, and two L-shaped plates 211 are fixedly connected to the top of the first valve body 101. The tops of the two L-shaped plates 211 are threadedly connected with threaded rods 212. The threaded rods 212 penetrate downward through the L-shaped plates 211, and two round holes that fit the threaded rods 212 are provided on the handle 207.

[0037] The arc-shaped two-way arrow is used to remind the user of the rotation direction of the handle 207. The two L-shaped plates 211 are used to limit the rotation range of the handle 207 to prevent the user from damaging the connection between the handle 207 and the insertion rod 201 when rotating the handle 207. The positions of the two L-shaped plates 211 correspond to the rotation closing and opening positions of the handle 207 respectively. By rotating the threaded rod 212 to insert it into the round hole of the handle 207, the handle 207 can be locked and the open or closed state of the valve ball 103 can be locked to prevent the worker from operating it incorrectly and causing the valve ball 103 to be accidentally closed or opened.

[0038] During use, when connecting the first valve body 101 and the second valve body 102, the two plug rods 201 are inserted into the positioning holes of the first valve body 101. When the plug rod 201 is inserted into the positioning holes, the limit block 202 is squeezed into the rectangular groove of the plug rod 201 by the positioning holes. When the plug rod 201 is no longer in contact with the positioning holes, the torsion spring 203 drives the limit block 202 to deflect and reset and limit the first valve body 101, so that the second valve body 102 is accurately aligned with the bolt holes of the first valve body 101, so as to facilitate the installation of bolts and nuts;

[0039] Then, the straight rod 208 is inserted into the through hole of the limit block 202 to prevent the pull ring 205 from being pulled. When disassembly is required, the straight rod 208 is pulled to disengage it from the through hole of the limit block 202 close to the position of the first valve body 101. Then, the two pull rings 205 pull the two limit blocks 202 synchronously downward to the rectangular grooves of the two plug rods 201 through the connecting rope 204. Then, the straight rod 208 is moved to another through hole of the limit block 202, so that the limit block 202 can always be located in the rectangular groove of the plug rod 201, and the restriction on the first valve body 101 is released, so that the first valve body 101 and the second valve body 102 can be separated from each other, so that other components can be disassembled, repaired and replaced.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
