Description

Technical Field

[0001] This utility model relates to the field of gate valves, and more specifically, to an impact-resistant gate valve. Background Art

[0002] Gate valves are one of the most commonly used shut-off valves, mainly used to connect or disconnect water flow in pipelines, rivers, and canals. Gate valves have a wide range of applications and are frequently seen in rivers and canals.

[0003] When gate valves are used in rivers or canals, water flows out when the valve plate is opened, carrying impurities such as stones. These stones can easily enter the groove at the bottom of the valve frame. When the valve plate closes again, the stones that have entered the groove will affect the sealing performance of the valve plate when it is closed. In addition, the valve's impact resistance is poor.

[0004] Therefore, we made improvements and proposed an impact-resistant gate valve. Utility Model Content

[0005] The purpose of this utility model is to address the issue that when gate valves are used in rivers or channels, the water flow when the valve plate is opened carries impurities such as stones. These stones can easily enter the groove at the bottom of the valve frame. When the valve plate is closed again, the stones entering the groove will affect the sealing performance of the valve plate when it is closed. In addition, the impact resistance is poor.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] Impact-resistant gate valves are used to improve the above problems.

[0008] The application is as follows:

[0009] The valve includes a valve frame with a groove at its bottom. A valve plate is slidably connected to the valve frame. A first circular groove and a second circular groove are formed inside the valve plate and are connected to the first circular groove. A first sliding rod is slidably connected inside the first circular groove. A second sliding rod is fixedly installed at the bottom of the first sliding rod. A baffle is fixedly installed at the bottom of the second sliding rod and is located at the bottom of the groove cavity. An L-shaped rod is fixedly installed on the valve frame. A first triangular block is integrally formed on the front of the L-shaped rod. A reinforcing mechanism is provided on the valve plate, and a driving mechanism is provided above the valve plate.

[0010] As a preferred technical solution of this application, the diameter of the first circular groove is the same as the diameter of the first sliding rod.

[0011] As a preferred technical solution of this application, the diameter of the second circular groove is the same as the diameter of the second slide rod.

[0012] As a preferred technical solution of this application, the diameter of the second slide rod is smaller than the diameter of the first slide rod.

[0013] As a preferred technical solution of this application, the reinforcing mechanism includes a reinforcing rod that is fixedly welded to the valve plate.

[0014] As a preferred technical solution of this application, a connecting block is fixedly installed on the top of the valve plate, and the driving mechanism includes a threaded rod rotatably connected to the connecting block. A handwheel is fixedly installed on the top of the threaded rod, and the threaded rod is threadedly connected to the valve frame.

[0015] As a preferred technical solution of this application, a sealing strip is adhered to the outer wall of the baffle.

[0016] As a preferred technical solution of this application, a long rod is fixedly welded to the valve plate, and a second triangular block is integrally formed on the front of the long rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In the scheme of this application:

[0019] 1. The valve plate moves upward along the valve frame. As the valve plate moves upward, the first circular groove slides along the first sliding rod (the first sliding rod remains stationary). When the first sliding rod is above the second circular groove, it is locked. At this time, the valve plate continues to move upward, which drives the first sliding rod to move upward. The first sliding rod then drives the second sliding rod to move upward, and the second sliding rod drives the baffle to move upward. When the gate plate moves to the top, the baffle is parallel to the groove on the valve frame (to prevent stones from entering the groove). During the upward movement of the baffle, it can carry out the stones that have entered the groove. At this time, the water flow will wash away the stones on the baffle, which solves the problem in the prior art where when the valve plate is opened, the water flow carries stones and other impurities. These stones can easily enter the groove at the bottom of the valve frame. When the valve plate is closed again, the stones entering the groove will affect the sealing of the valve plate when it is closed.

[0035] like Figure 1-7 As shown, this embodiment proposes an impact-resistant gate valve, including a valve frame 1. A groove 2 is formed at the bottom of the valve frame 1. A valve plate 3 is slidably connected to the valve frame 1. When the valve plate 3 is closed, it is inserted into the groove 2. A first circular groove 4 and a second circular groove 5 are formed within the valve plate 3, communicating with the first circular groove 4. A first sliding rod 6 is slidably connected within the first circular groove 4. A second sliding rod 7 is fixedly installed at the bottom of the first sliding rod 6. The diameter of the first circular groove 4 is the same as the diameter of the first sliding rod 6, and the diameter of the second circular groove 5 is the same as the diameter of the second sliding rod 7. The diameter of the second sliding rod 7 is smaller than the diameter of the first sliding rod 6. A baffle 8 is fixedly installed at the bottom of the second sliding rod 7. When the valve plate 3 moves upward, the first circular groove 4 slides along the first sliding rod 6 (the first sliding...). (With rod 6 stationary), when the first sliding rod 6 is above the second circular groove 5, the first sliding rod 6 is locked. At this time, the valve plate 3 continues to move upward, which can drive the first sliding rod 6 to move upward. The first sliding rod 6 then drives the second sliding rod 7 to move upward, and the second sliding rod 7 drives the baffle 8 to move upward. The baffle 8 is located at the bottom of the inner cavity of the groove 2. An L-shaped rod 9 is fixedly installed on the valve frame 1. The front of the L-shaped rod 9 is integrally formed with a first triangular block 10. A reinforcing mechanism is provided on the valve plate 3, and a driving mechanism is provided above the valve plate 3. When this gate valve is in use, it can disperse the impact force of the water flow, resulting in good impact resistance. It can also prevent stones from entering the groove 2 at the bottom of the valve frame 1, solving the problem that stones can easily enter the groove 2 and affect the sealing of the valve plate when it is closed.

[0036] The reinforcement mechanism includes a reinforcing rod 13 fixedly welded to the valve plate 3, which increases the impact resistance of the valve plate 3.

[0037] A connecting block 15 is fixedly installed on the top of the valve plate 3. The driving mechanism includes a threaded rod 16 rotatably connected to the connecting block 15. A handwheel 17 is fixedly installed on the top of the threaded rod 16. The threaded rod 16 is threadedly connected to the valve frame 1. Rotating the handwheel 17 causes the threaded rod 16 to rotate. The rotation of the threaded rod 16 causes the connecting block 15 to move upward. The connecting block 15 causes the valve plate 3 to move upward.

[0038] A sealing strip 14 is adhered to the outer wall of the baffle 8 to prevent impurities from entering.

[0039] A long rod 11 is fixedly welded onto the valve plate 3. A second triangular block 12 is integrally formed on the front of the long rod 11. The first triangular block 10 and the second triangular block 12 are set to disperse the force of the water.

[0040] Specifically, when using this impact-resistant gate valve: Turning the handwheel 17 rotates the threaded rod 16, which in turn moves the connecting block 15 upwards. The connecting block 15 then moves the valve plate 3 upwards, causing the valve plate 3 to move upwards along the valve frame 1. As the valve plate 3 moves upwards, the first circular groove 4 slides along the first sliding rod 6 (the first sliding rod 6 remains stationary). When the first sliding rod 6 is above the second circular groove 5, it is locked. At this point, if the valve plate 3 continues to move upwards, it can move the first sliding rod 6 upwards, which in turn moves the second sliding rod 7 upwards. The second sliding rod 7 then moves the stop... When the gate 3 moves to the top, the baffle 8 is parallel to the groove 2 on the valve frame 1 (to prevent stones from entering the groove 2). As the baffle 8 moves upward, it can carry out the stones that have entered the groove 2. At this time, the water flow will wash away the stones on the baffle 8. The first triangular block 10 and the second triangular block 12 can disperse the force of the water flow. When this gate valve is in use, it can disperse the force of the water flow, resulting in good impact resistance. It can also prevent stones from entering the groove 2 at the bottom of the valve frame 1, thus solving the problem that stones can easily enter the groove 2 and affect the sealing of the valve plate when it is closed.

[0041] All technical features in this embodiment can be freely combined according to actual needs.

[0042] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
