Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically a valve that is easy to install. Background Technology

[0002] Valves are control components in fluid transport systems, with functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, diversion, or overflow pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of types and specifications. Existing valves are generally large in size and heavy in weight, requiring two people to work together when installing them. However, when the valve is installed in a corner or bend, it is impossible for two people to work together, making installation inconvenient or even impossible.

[0003] Chinese patent discloses a valve that is easy to install (authorization announcement number CN219082421U). This patented technology uses a connecting seat installed on the top of the pipe, and a support plate installed on the connecting seat and a support rod installed on the support plate to raise the valve, which is convenient for workers to install. The height of the support rod can be adjusted according to the installation height of the valve. The process is convenient and simple, does not require the cooperation of many people, and is highly practical.

[0004] However, it has certain drawbacks: when adjusting the height of the valve body, it is necessary to either lift the valve body away from the ground and then rotate the support rod to lower it, or directly rotate the support rod on the ground to lower it. The former requires lifting the valve body and bearing its weight for a long time, while the latter requires rotating the support rod to overcome the friction between it and the ground. Both methods are time-consuming and laborious, and cannot easily and quickly adjust the height of the valve body. Utility Model Content

[0005] The purpose of this invention is to provide a valve that is easy to install, so as to solve the problems mentioned in the background art.

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

[0007] A valve that is easy to install includes a valve body. A lifting mechanism is provided on the front surface of the valve body. The lifting mechanism includes an adjusting seat. A rack is movably connected through the upper and lower surfaces of the adjusting seat. A base plate is fixed to the lower end of the rack. A rotating rod is movably connected through the front surface of the adjusting seat. A bearing sleeve is installed at the rear end of the rotating rod. A gear is fixedly connected to the outer surface of the rotating rod inside the adjusting seat. A ratchet is fixedly connected to the outer surface of the rotating rod in front of the adjusting seat. A positioning mechanism is provided on the front surface of the adjusting seat above the rotating rod. A fixing mechanism is provided on the rear surface of the adjusting seat.

[0008] As a further embodiment of this utility model: the positioning mechanism includes a spring, a positioning block is fixedly connected to the upper end of the spring, and a pawl is fixedly connected to the lower end of the spring, with a positioning rod rotatably connected to the left end of the pawl.

[0009] As a further embodiment of this utility model: the fixing mechanism includes a fixing frame, a fixing bolt is movably connected through the left side surface of the fixing frame, and a fixing block is movably connected inside the fixing frame.

[0010] As a further embodiment of this utility model: the rack is slidably connected to the inner right side surface of the adjusting seat, the base plate is located below the valve body, the bearing sleeve is fixedly connected to the inner rear surface of the adjusting seat, and the gear is meshed with the rack.

[0011] As a further embodiment of this utility model: the pawl is attached to the ratchet, and the rear ends of the positioning block and the positioning rod are both fixed to the front surface of the adjusting seat.

[0012] As a further embodiment of this utility model: the front end of the fixing frame is fixedly connected to the rear end of the adjusting seat, the fixing bolt is threadedly connected to the inside of the fixing block, and the rear end of the fixing block is fixedly connected to the front surface of the valve body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model features a lifting mechanism. By raising the valve body upwards, the adjusting seat can be lifted by the fixing mechanism within the lifting mechanism, thereby adjusting the valve body to the required installation height. When the valve body is released, the pawl engages with the ratchet, preventing the rotating rod from turning counterclockwise, and thus the valve body will not descend. This allows for easy and convenient adjustment of the valve body to the desired height. After removing the fixing bolt, the fixing block in the lifting mechanism can be separated from other structures, leaving only the fixing block on the surface of the valve body.

[0020] Please see Figures 1-4 In this embodiment of the utility model, a valve that is easy to install includes a valve body 1. A lifting mechanism 2 is provided on the front surface of the valve body 1. The lifting mechanism 2 includes an adjusting seat 3. A rack 4 is movably connected to the upper and lower surfaces of the adjusting seat 3. The rack 4 is slidably connected to the inner right surface of the adjusting seat 3. A base plate 5 is fixedly connected to the lower end of the rack 4. The base plate 5 is located below the valve body 1. A rotating rod 6 is movably connected to the front surface of the adjusting seat 3. A bearing sleeve 7 is installed at the rear end of the rotating rod 6. The bearing sleeve 7 is fixedly connected to the inner rear surface of the adjusting seat 3. A gear 8 is fixedly connected to the outer surface of the rotating rod 6 inside the adjusting seat 3. The gear 8 is meshed with the rack 4. A ratchet 9 is fixedly connected to the outer surface of the rotating rod 6 in front of the adjusting seat 3. A positioning mechanism 10 is provided above the rotating rod 6. The positioning mechanism 10 includes a spring 11. A positioning block 12 is fixedly connected to the upper end of the spring 11, and a pawl 13 is fixedly connected to the lower end of the spring 11. The pawl 13 is attached to the ratchet 9. A positioning rod 14 is rotatably connected to the left end of the pawl 13. The rear ends of the positioning block 12 and the positioning rod 14 are both fixedly connected to the front surface of the adjusting seat 3. A fixing mechanism 15 is provided on the rear surface of the adjusting seat 3. The fixing mechanism 15 includes a fixing frame 16. The front end of the fixing frame 16 is fixedly connected to the rear end of the adjusting seat 3. A fixing bolt 17 is movably connected through the left side surface of the fixing frame 16, and a fixing block 18 is movably connected inside the fixing frame 16. The fixing bolt 17 is threadedly connected inside the fixing block 18, and the rear end of the fixing block 18 is fixedly connected to the front surface of the valve body 1.

[0021] The bearing sleeve 7 includes a bearing housing and a bearing installed inside the bearing housing. The bearing housing and the bearing are rotatable relative to each other. The rotating rod 6 is fixed in the bearing, so the rotating rod 6 and the bearing sleeve 7 are rotatable relative to each other.

[0022] When the rotating rod 6 rotates clockwise, the pawl 13 will not jam the ratchet 9, meaning the rotating rod 6 can rotate clockwise normally; when the rotating rod 6 rotates counterclockwise, the pawl 13 will jam the ratchet 9, meaning the rotating rod 6 cannot rotate counterclockwise normally.

[0023] Lifting the valve body 1 upwards can move the adjusting seat 3 upwards. At this time, the rotating rod 6 rotates clockwise, thereby raising the valve body 1 to the required installation height. After releasing the valve body 1, the pawl 13 locks the ratchet 9, preventing the valve body 1 from falling. After pulling the pawl 13 away from the ratchet 9, the valve body 1 can be moved downwards.

[0024] After removing the fixing bolt 17, the fixing block 18 in the lifting mechanism 2 can be separated from other structures, so that only the fixing block 18 remains on the valve body 1.

[0025] The working principle of this utility model is as follows: When in use, pull the valve body 1 upward and drive the adjusting seat 3 upward through the fixing mechanism 15, thereby raising the valve body 1 to the installation height; release the valve body 1, and because the pawl 13 is locked in the ratchet 9, the valve body 1 will not fall down, and then fix the valve body 1 to the pipeline; finally, rotate the fixing bolt 17 to remove it, and separate the fixing frame 16 from the fixing block 18, so that only the fixing block 18 remains on the valve body 1.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
