Description

Technical Field

[0001] This utility model relates to the field of gate valve technology, and in particular to a gate valve with a lateral lifting function. Background Technology

[0002] Gate valves are a common type of valve used to control the flow of fluids (liquid or gas) in pipelines. They are opened or closed by the movement of a flat plate (gate) perpendicular to the flow direction, thereby controlling the passage of fluid. Gate valves are suitable for a variety of different fluids and pressure conditions and are widely used in industrial pipeline systems.

[0003] However, in most common devices on the market, the drive component is usually mounted at the top. This design is often affected by the installation environment, potentially interfering with proper installation. Furthermore, because the lifting height of the sealing plate cannot be effectively monitored, operator errors may cause the sealing plate to fail to accurately rise or fall to the intended position. Therefore, there is an urgent need to design a gate valve with a lateral lifting function to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a gate valve with a lateral lifting function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A gate valve with a lateral lifting function includes a main body, a mounting base is provided on the top of the main body, and a detection component and a locking component are respectively provided inside the mounting base;

[0007] The detection assembly includes an assembly slot and a scale slot. A connecting seat is bolted to the top outer wall of one side of the assembly seat. A multi-section electric cylinder is bolted to the inside side of the connecting seat. A piston plate is bolted to the output end of the multi-section electric cylinder. A hydraulic cylinder and a pneumatic rod are bolted to the top inner wall of the assembly slot. The pneumatic rod is connected to the scale slot through a pipe. A scale plate is slidably connected inside the scale slot. A push plate is bolted to the output end of the pneumatic rod.

[0008] The key concept of the above technical solution lies in the following: by setting up a multi-section electric cylinder, when the multi-section electric cylinder is activated, it can drive the piston plate to move. The piston plate injects hydraulic oil into the hydraulic cylinder, which in turn pushes the lifting rod to move the push plate. The push plate's function is to extend and retract the air rod, so that gas can enter the air rod. Through the action of air pressure, the scale plate can move freely within the scale groove. This design not only enables the device to detect the lifting height of the sealing plate, but also provides users with a convenient equipment assembly method through the lateral installation of the connecting seat.

[0009] Preferably, the connecting seat is connected to the hydraulic cylinder via a pipe, and the interior of the connecting seat is filled with hydraulic oil.

[0010] Preferably, the locking assembly includes a lifting rod, and the bottom outer wall of the push plate is bolted to both sides to form sealing plates extending into the interior of the main body.

[0011] Preferably, the locking assembly further includes auxiliary seats installed on both sides of the mounting base, and the inner wall of the mounting base is provided with a movable groove arranged on the same side as the auxiliary seats.

[0012] Preferably, a screw extending into the moving groove is movably mounted inside the auxiliary seat via a bearing, and a positioning block inserted into the lifting rod is threaded onto the outer wall of the screw.

[0013] Preferably, the top and bottom of the movable groove are provided with limiting grooves, and the two outer walls of the positioning block are bolted with limiting plates that are slidably connected to the inside of the limiting grooves.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. With the multi-section electric cylinder, when the multi-section electric cylinder is activated, it can drive the piston plate to move. The piston plate injects hydraulic oil into the hydraulic cylinder, which in turn pushes the lifting rod to move the push plate. The push plate's function is to extend and retract the air rod, so that gas can enter the air rod. Through the action of air pressure, the scale plate can move freely within the scale groove. This design not only enables the device to detect the lifting height of the sealing plate, but also provides users with a convenient equipment assembly method through the lateral installation of the connecting seat.

[0016] 2. With the screw installed, when the screw is rotated, the screw engages with the positioning block through the thread, enabling the positioning block to move the limiting plate within the limiting groove. During the movement of the positioning block, the positioning block inserts into the lifting rod. This design structure can prevent damage to the multi-section electric cylinder or hydraulic cylinder due to the lack of a locking mechanism, thereby extending the service life of the device.

[0025] Please also see Figure 1 , Figure 2 and Figure 3 A gate valve with a lateral lifting function includes a main body 1, a mounting base 2 is provided on the top of the main body 1, and a detection component 3 and a locking component 4 are respectively provided inside the mounting base 2.

[0026] The detection component 3 includes an assembly slot 31 and a scale slot 32. A connecting seat 33 is bolted to the top outer wall of one side of the assembly base 2. A multi-section electric cylinder 34 is bolted to the inside of the connecting seat 33. A piston plate 35 is bolted to the output end of the multi-section electric cylinder 34. A hydraulic cylinder 36 and a pneumatic rod 37 are bolted to the top inner wall of the assembly slot 31. The pneumatic rod 37 is connected to the scale slot 32 through a pipe. A scale plate 38 is slidably connected inside the scale slot 32. A push plate 39 is bolted to the output end of the pneumatic rod 37. When the multi-section electric cylinder 34 is activated, it drives the piston plate 35 to move. The piston plate 35 then injects hydraulic oil into the hydraulic cylinder 36. During the continuous injection of hydraulic oil, the hydraulic oil pushes the lifting rod. When the lifting rod 41 moves, it drives the push plate 39 to move. The push plate 39 can drive the air rod 37 to extend and retract. During the extension and retraction of the air rod 37, the gas inside the scale groove 32 will enter the air rod 37. Using the air pressure, the scale plate 38 can move inside the scale groove 32, which makes it easier for the operator to detect the lifting height of the sealing plate 42. This avoids the problem that the existing equipment is not convenient for observing the lifting height of the sealing plate 42, thus affecting the user's use of the equipment. The connecting seat 33 is connected to the hydraulic cylinder 36 through a pipe. The connecting seat 33 is filled with hydraulic oil. When the hydraulic oil inside the connecting seat 33 moves, the connecting seat 33 can use the interconnection with the hydraulic cylinder 36 to provide power transmission for the lifting rod 41 to move up and down.

[0027] See Figure 1 and Figure 4The locking assembly 4 includes a lifting rod 41. A sealing plate 42 extending into the interior of the main body 1 is bolted to both sides of the bottom outer wall of the push plate 39. During descent, the lifting rod 41 can drive the sealing plate 42 to insert into the interior of the main body 1. The locking assembly 4 also includes auxiliary seats 43 mounted on both sides of the mounting base 2. Movable grooves 44 are formed on the inner walls of both sides of the mounting base 2, corresponding to one side of the auxiliary seat 43. The auxiliary seat 43 provides an installation position for the screw 45, and during rotation, the screw 45 can rotate within the auxiliary seat 43. An extension into the movable groove is movably mounted inside the auxiliary seat 43 via a bearing. Inside the groove 44 is a screw 45, and on the outer wall of the screw 45 is a threaded connection to a positioning block 46 that is inserted into the lifting rod 41. When the screw 45 is rotated, the screw 45 can use the threaded connection with the positioning block 46 to allow the positioning block 46 to be inserted into the lifting rod 41. Limiting grooves 47 are provided on the top and bottom of the movable groove 44. Limiting plates 48 are slidably connected to the limiting grooves 47 by bolts on the outer walls of both sides of the positioning block 46. When the positioning block 46 moves, the positioning block 46 can drive the limiting plates 48 to slide inside the limiting grooves 47. This structure facilitates the operator's locking function of the sealing plate 42.

[0028] With the above-mentioned design, when the screw 45 is rotated, it engages with the positioning block 46 through a threaded connection, allowing the positioning block 46 to move the limiting plate 48 within the limiting groove 47. During the movement of the positioning block 46, the positioning block 46 inserts into the lifting rod 41. This design structure can prevent damage to the multi-section electric cylinder 34 or hydraulic cylinder 36 due to the lack of a locking mechanism, thereby extending the service life of the device.

[0030] A gate valve with a lateral lifting function includes a main body 1, a mounting base 2 is provided on the top of the main body 1, and a detection component 3 and a locking component 4 are respectively provided inside the mounting base 2.

[0031] The detection component 3 includes an assembly slot 31 and a scale slot 32. A connecting seat 33 is bolted to the top outer wall of one side of the assembly base 2. A multi-section electric cylinder 34 is bolted to the inside of the connecting seat 33. A piston plate 35 is bolted to the output end of the multi-section electric cylinder 34. A hydraulic cylinder 36 and a pneumatic rod 37 are bolted to the top inner wall of the assembly slot 31. The pneumatic rod 37 is connected to the scale slot 32 through a pipe. A scale plate 38 is slidably connected inside the scale slot 32. A push plate 39 is bolted to the output end of the pneumatic rod 37. When the multi-section electric cylinder 34 is activated, it can drive the piston plate 35 to move. Plate 35 will drive the hydraulic oil inside it to be injected into the hydraulic cylinder 36. During the continuous injection of hydraulic oil, the hydraulic oil will push the lifting rod 41 to move. The lifting rod 41 will drive the push plate 39 to move. The push plate 39 can drive the air rod 37 to extend and retract. During the extension and retraction of the air rod 37, the gas inside the scale groove 32 will enter the air rod 37. Using the air pressure, the scale plate 38 can be driven to move inside the scale groove 32. This makes it easier for the operator to detect the lifting height of the sealing plate 42, thus avoiding the problem that the existing equipment is not convenient for observing the lifting height of the sealing plate 42, which would affect the user's use of the equipment.

[0032] The connecting seat 33 is connected to the hydraulic cylinder 36 via a pipe. The interior of the connecting seat 33 is filled with hydraulic oil. When the hydraulic oil inside the connecting seat 33 moves, the connecting seat 33 can use its connection with the hydraulic cylinder 36 to provide power transmission for the lifting rod 41 to move up and down. The locking assembly 4 includes the lifting rod 41. The bottom outer wall of the push plate 39 is bolted to both sides and the sealing plate 42 extending into the interior of the main body 1. When the lifting rod 41 is descending, the lifting rod 41 can drive the sealing plate 42 to insert into the interior of the main body 1. The locking assembly 4 also includes auxiliary seats 43 installed on both sides of the mounting base 2. The inner wall of the mounting base 2 is provided with a moving groove 44 on the same side as the auxiliary seat 43. The auxiliary seat 43 can provide an installation position for the screw 45 and rotate the screw 45. During operation, the screw 45 can rotate inside the auxiliary seat 43. Inside the auxiliary seat 43, the screw 45 extends into the moving groove 44 via a bearing. The outer wall of the screw 45 is threaded with a positioning block 46 that is inserted into the lifting rod 41. When the screw 45 is rotated, it can use the threaded connection with the positioning block 46 to allow the positioning block 46 to be inserted into the lifting rod 41. Limiting grooves 47 are provided on the top and bottom of the moving groove 44. Limiting plates 48 are bolted to the outer walls of both sides of the positioning block 46 and are slidably connected to the limiting grooves 47. When the positioning block 46 moves, it can drive the limiting plates 48 to slide inside the limiting grooves 47. This structure facilitates the operator's locking function of the sealing plate 42.

[0033] Working principle: In use, first, install the device in the designated position, then start the multi-section electric cylinder 34 as required. During the operation of the multi-section electric cylinder 34, it drives the piston plate 35 to move. During the movement of the piston plate 35, it drives hydraulic oil to be injected into the hydraulic cylinder 36. During the continuous injection of hydraulic oil, the hydraulic oil pushes the lifting rod 41 to move. The lifting rod 41 drives the push plate 39 to move. The push plate 39 drives the air rod 37 to extend and retract. During the extension and retraction of the air rod 37, the graduated groove 32... The gas inside enters the air rod 37 and uses the air pressure to drive the scale plate 38 to move inside the scale groove 32. When the lifting rod 41 is raised or lowered to the designated position, the screw 45 inside the auxiliary seat 43 is rotated. During the rotation of the screw 45, the screw 45 can be threadedly connected to the positioning block 46, so that the positioning block 46 is inserted into the lifting rod 41. During the movement of the positioning block 46, the positioning block 46 can drive the limiting plate 48 to slide inside the limiting groove 47, thereby achieving the locking of the sealing plate 42.
