Description

Technical Field

[0001] The utility model relates to the technical field of gate valves, in particular to a multi-valve seat gate valve. Background Art

[0002] A gate valve typically includes a valve housing for the gate valve in a retracted (open) position and a fluid passage for connection with a pipeline. As the name implies, the valve operates like a gate by moving between an open position in the valve housing and a closed position in the fluid passage. Once closed, the valve is essentially sealed and prevents or impedes the movement of fluid through the fluid passage. The ability to achieve an adequate seal depends on the various gate valve designs. Most common multi-seat gate valves can generally be classified as including two-piece gate valve designs and three-piece gate valve designs.

[0003] For example, a multi-valve seat gate valve with publication number CN202321075775.6 includes a pipeline, a seat gate valve is fixedly connected to the right side of the pipeline, and a fixed block is fixedly connected to the upper surface of the seat gate valve. The utility model rotates the rotating block 1 to make the threaded column rotate under the action of the rotating column and the rotating circular plate, and the inner cavity of the seat gate valve is sealed by the action of the sealing ring 1, and the gate valve threadedly sleeved on the outer wall of the threaded column moves downward under the action of the seat gate valve through the action of the threaded column, so that the gate valve moves to the upper surface of the sealing block, and the outer wall of the gate valve and the seat gate valve are sealed by the action of the sealing ring 2 fixedly connected to the outer wall of the gate valve, and the lower surface of the sealing gasket 1 overlaps with the upper surface of the fixed square plate through the action of the threaded column, so that the fixed square plate and the gate valve are sealed, and the water flow is intercepted by the action of the gate valve, thereby achieving the purpose of better sealing interception.

[0004] The multi-seat gate valve proposed in this patent usually adopts a threaded fixing installation method when connecting the docking pipe to the pipe of the connecting object. This installation method makes the connection of the pipe easily deformed or damaged after being hit by external force, thereby affecting the stability of the installation and use of the valve seat gate valve.

[0005] Therefore, we propose a multi-seat gate valve to solve the above problems. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1: Please refer to Figure 1-4 The utility model provides a technical solution: a multi-valve seat gate valve, comprising a seat gate valve body 1 and a fixing component 2 arranged at the upper end of the seat gate valve body 1, first pipes 3 are arranged on both sides of the lower end of the outer wall of the seat gate valve body 1, a second pipe 4 is fixedly installed on one side of the first pipe 3 by screws, a protective component 5 is embedded and installed at the connection between the first pipe 3 and the second pipe 4, and limiting components 6 are arranged at both ends of one side of the outer wall of the protective component 5. The setting of the protective component 5 is used to improve the stability of the connection between the first pipe 3 and the second pipe 4.

[0026] The protection component 5 includes an upper containing mechanism 51 and a lower containing mechanism 52 arranged at the lower end of the upper containing mechanism 51 . An inner groove 53 is opened in the middle of the inner cavity of the upper containing mechanism 51 and the lower containing mechanism 52 . A sealing gasket 54 is embedded in the inner wall of the inner groove 53 .

[0027] The upper containing mechanism 51 comprises a first semicircular block 511 and insertion blocks 512 fixedly mounted on both sides of the lower end of the first semicircular block 511 , and a plurality of triangular inclined blocks 513 are fixedly mounted linearly and evenly spaced on one side of the outer wall of the insertion block 512 .

[0028] The lower containing mechanism 52 includes a second semicircular block 521 and an insertion groove 522 opened on both sides of the upper end of the second semicircular block 521, long grooves 523 are respectively opened on both sides of the upper end of the outer wall of the second semicircular block 521, retaining grooves 524 are opened on both sides of the inner wall of the long groove 523, and movable grooves 525 are opened in the middle of both sides of the outer wall of the second semicircular block 521, and the insertion block 512 is movably plugged and installed in the inner cavity of the insertion groove 522.

[0029] The retaining mechanism 61 includes a connecting block 611 and a corresponding triangular block 612 fixedly installed at one end of the connecting block 611, an extension block 613 is fixedly installed on one side of the outer wall of the connecting block 611, and an elastic element 614 is fixedly installed in the middle of one end of the extension block 613. One end of the retaining mechanism 61 is movably installed in the inner cavity of the movable groove 525. A connecting long groove is opened on one side of the inner wall of the movable groove 525, which is not shown in the figure. One end of the elastic element 614 is fixedly installed on one end of the inner wall of the connecting long groove, and the extension block 613 is movably installed in the inner cavity of the connecting long groove.

[0030] Specifically, after the operator fixes and installs the first pipe 3 and the second pipe 4 with screws, the operator uses the upper containing mechanism 51 and the lower containing mechanism 52 to wrap the outer walls of the first pipe 3 and the second pipe 4 respectively, so that the insertion blocks 512 on both sides of the lower end of the first semicircular block 511 drive the triangular inclined block 513 to be inserted into the inner cavity of the insertion groove 522. After the triangular inclined block 513 enters the inner cavity of the insertion groove 522, it will be pressed by the corresponding triangular block 612 movably installed in the inner cavity of the movable groove 525, thereby fixing the insertion block 512 in the inner cavity of the insertion groove 522, completing the installation of the first semicircular block 511. The fixed installation of the semicircular block 511 and the second semicircular block 521 can drive the corresponding triangular block 612 to move by pulling the connecting block 611, so that the extension block 613 fixedly installed at one end of the connecting block 611 drives the elastic element 614 to contract. The connecting long groove opened on one side of the inner wall of the movable groove 525 is not shown in the figure, and the insertion block 512 can be taken out to complete the disassembly of the first semicircular block 511. The connection between the first pipe 3 and the second pipe 4 is fixed by the upper containing mechanism 51 and the lower containing mechanism 52, thereby improving the stability of the setting of the connection between the first pipe 3 and the second pipe 4.

[0031] Example 2: Please refer to Figure 5 The limiting assembly 6 includes a retaining mechanism 61 and a mounting mechanism 62 movably mounted around the outer wall of the retaining mechanism 61 , and a long magnetic rod 63 is magnetically connected in the inner cavity of the retaining mechanism 61 and the mounting mechanism 62 .

[0032] The mounting mechanism 62 includes a concave block 621 and a cross clamp block 622 fixedly installed at both ends of one side of the concave block 621. A circular magnetic groove 623 is opened in the middle of one side of the outer wall of the concave block 621. The long magnetic rod 63 is inserted through the circular magnetic groove 623 and the magnetic hole groove opened in the middle of one end of the connecting block 611 for magnetic fixation. The cross clamp block 622 is movably installed in the inner cavity of the long groove 523 and the retaining groove 524.

[0033] Specifically, the operator can move the concave block 621 to the outer wall of the connecting block 611 so that the circular magnetic groove 623 and the magnetic hole groove opened in the middle of one end of the connecting block 611 correspond to each other, and then use the long magnetic rod 63 to pass through the circular magnetic groove 623 and the magnetic hole groove in the middle of one end of the connecting block 611, so that the long magnetic rod 63 is magnetically connected in the inner cavity of the circular magnetic groove 623 and the magnetic hole groove in the middle of one end of the connecting block 611, and then the connecting block 611 is protected by the concave block 621, thereby improving the safety of the connecting block 611 when not in use.

[0034] Working principle: After the operator fixes and installs the first pipe 3 and the second pipe 4 with screws, the operator uses the upper containing mechanism 51 and the lower containing mechanism 52 to wrap the outer walls of the first pipe 3 and the second pipe 4 respectively, so that the insertion blocks 512 on both sides of the lower end of the first semicircular block 511 drive the triangular inclined block 513 to be inserted into the inner cavity of the insertion groove 522. After the triangular inclined block 513 enters the inner cavity of the insertion groove 522, it will be pressed by the corresponding triangular block 612 movably installed in the inner cavity of the movable groove 525, and then the insertion block 512 is fixedly installed in the inner cavity of the insertion groove 522, completing the fixed installation of the first semicircular block 511 and the second semicircular block 521. Since the corresponding triangular block 612 can be driven to move by pulling the connecting block 611, The extension block 613 fixedly installed at one end of the connecting block 611 drives the elastic element 614 to contract the connecting long groove opened on one side of the inner wall of the movable groove 525 (not shown in the figure), and the insertion block 512 can be taken out to complete the disassembly of the first semicircular block 511. In order to prevent the connecting block 611 from being accidentally touched, the concave block 621 can be moved to the surrounding of the outer wall of the connecting block 611 so that the circular magnetic groove 623 and the magnetic hole groove opened in the middle of one end of the connecting block 611 correspond to each other, and then the long magnetic rod 63 is inserted through the circular magnetic groove 623 and the magnetic hole groove in the middle of one end of the connecting block 611, so that the long magnetic rod 63 is magnetically connected to the circular magnetic groove 623 and the inner cavity of the magnetic hole groove in the middle of one end of the connecting block 611, and the connecting block 611 is protected by the concave block 621.
