Description

Technical Field

[0001] This utility model relates to the field of high-pressure gate valve technology, specifically a high-pressure gate valve with lubrication function. Background Technology

[0002] A high-pressure gate valve is a type of valve that controls the opening and closing of fluids by raising and lowering a gate. It is mainly used for shutting off medium and large diameter pipelines. It consists of a valve body, valve cover, gate, valve stem, valve seat, and sealing components. The gate is perpendicular to the fluid direction and can be fully opened or fully closed by raising and lowering. It is mainly used to shut off the medium (such as water, gas, liquid, etc.) in the pipeline and is not suitable for flow regulation. The gate and valve seat are in close contact to form a seal. The fluid passage is controlled by changing the position of the gate (fully engaged or disengaged). The sealing surface must be kept smooth. Wedge-shaped or wedge-shaped structures are usually used to enhance the sealing performance.

[0003] Existing high-pressure gate valves typically use simple lubrication and sealing methods such as applying grease or installing sealing rings, but these methods have obvious drawbacks and increase the workload of operators. Utility Model Content

[0004] The purpose of this invention is to provide a high-pressure gate valve with lubrication function, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-pressure gate valve with lubrication function, comprising a high-pressure gate valve body.

[0006] A connecting flange that is fixedly installed on the side wall of the high-pressure gate valve body;

[0007] And a lubrication assembly located on the side of the high-pressure gate valve body;

[0008] The lubrication assembly includes a lubrication mechanism located on the side of the high-pressure gate valve body;

[0009] An auxiliary mechanism is provided on the side of the high-pressure gate valve body, and the auxiliary mechanism is connected to the lubrication mechanism.

[0010] Preferably, a driving device is fixedly installed on the top of the high-pressure gate valve body, and the output end of the driving device is connected to the inner wall of the high-pressure gate valve body.

[0011] Preferably, the lubrication mechanism includes a stabilizing bracket, which is fixedly installed on the side wall of the high-pressure gate valve body. A rectangular chamber is fixedly installed on the inner wall of the stabilizing bracket. A sealing piston is slidably installed on the inner wall of the rectangular chamber. A sliding rod is fixedly installed at the bottom of the sealing piston. The bottom of the sliding rod extends movably through the inner wall of the rectangular chamber to the bottom of the rectangular chamber and is fixedly installed with a pull block. An output pipe is fixedly installed on the side wall of the rectangular chamber. The other end of the output pipe is fixedly connected to the side wall of the high-pressure gate valve body. A one-way valve pipe is fixedly installed on the top of the rectangular chamber.

[0012] Preferably, the inner wall of the one-way valve pipe is connected to the interior of the rectangular chamber, and the inner wall of the rectangular chamber is connected to the interior of the output pipe.

[0013] Preferably, the auxiliary mechanism includes a storage chamber, which is fixedly installed on the side wall of the high-pressure gate valve body. A feed pipe is fixedly installed on the top of the storage chamber, and the side wall of the storage chamber is fixedly connected to one end of the one-way valve pipe.

[0014] Preferably, a triangular bracket is fixedly installed on the side wall of the storage compartment, and the side wall of the triangular bracket is fixedly connected to the side wall of the high-pressure gate valve body. The stability of the storage compartment can be improved by the triangular bracket.

[0015] Preferably, there are two connecting flanges, both of which are of equal shape and size, and are symmetrically arranged with respect to the center face of the high-pressure gate valve body in the left-right direction.

[0016] This utility model provides a high-pressure gate valve with lubrication function. It has the following beneficial effects:

[0017] (1) When the operator needs to add lubricant to the inner wall of the high-pressure gate valve body, the pull block is first pulled down. The pull block moves the sliding rod, which in turn moves the sealing piston to slide on the inner wall of the rectangular chamber. At this time, the lubricant inside the storage chamber is transported to the inner wall of the rectangular chamber through the one-way valve pipe. Then, by lifting the pull block, the pull block moves the sliding rod to slide on the sealing piston. The sealing piston slides on the inner wall of the rectangular chamber, and the lubricant is transported to the inner wall of the output pipe and further enters the inner wall of the high-pressure gate valve body to further lubricate the inside of the high-pressure gate valve body. This solves the problem that existing high-pressure gate valves usually use methods such as applying grease or installing sealing rings for simple lubrication and sealing, but these methods have obvious defects and increase the workload of the operator.

[0018] (2) When the operator uses the high pressure gate valve body, the position of the high pressure gate valve body can be stabilized by the connecting flanges on both sides of the high pressure gate valve body. Then, lubricating oil can be added to the inner wall of the storage chamber through the feed pipe for storage. Attached Figure Description

[0024] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0025] Example 1: A preferred embodiment of the high-pressure gate valve with lubrication function provided by this utility model is as follows: Figures 1 to 4 As shown: A high-pressure gate valve with lubrication function includes a high-pressure gate valve body 1.

[0026] A connecting flange 2 is fixedly installed on the side wall of the high-pressure gate valve body 1. A drive device 3 is fixedly installed on the top of the high-pressure gate valve body 1. The output end of the drive device 3 is connected to the inner wall of the high-pressure gate valve body 1. There are two connecting flanges 2. The two connecting flanges 2 are equal in shape and size. The two connecting flanges 2 are symmetrically arranged with respect to the middle face in the left and right directions of the high-pressure gate valve body 1.

[0027] And a lubrication assembly 4 located on the side of the high-pressure gate valve body 1;

[0028] Lubrication assembly 4 includes a lubrication mechanism 41 located on the side of the high-pressure gate valve body 1;

[0029] An auxiliary mechanism 42 is provided on the side of the high-pressure gate valve body 1, and the auxiliary mechanism 42 is connected to the lubrication mechanism 41.

[0030] The lubrication mechanism 41 includes a stabilizing bracket 412, which is fixedly installed on the side wall of the high-pressure gate valve body 1. A rectangular chamber 411 is fixedly installed on the inner wall of the stabilizing bracket 412. A sealing piston 417 is slidably installed on the inner wall of the rectangular chamber 411. A sliding rod 414 is fixedly installed at the bottom of the sealing piston 417. The bottom of the sliding rod 414 extends through the inner wall of the rectangular chamber 411 to the bottom of the rectangular chamber 411 and is fixedly installed with a pull block 413. An output pipe 415 is fixedly installed on the side wall of the rectangular chamber 411. The other end of the output pipe 415 is fixedly connected to the side wall of the high-pressure gate valve body 1. A one-way valve pipe 416 is fixedly installed on the top of the rectangular chamber 411.

[0031] In this embodiment, the inner wall of the one-way valve pipe 416 is connected to the interior of the rectangular chamber 411, and the inner wall of the rectangular chamber 411 is connected to the interior of the output pipe 415.

[0032] In the specific implementation process, when the operator needs to add lubricant to the inner wall of the high-pressure gate valve body 1, first pull down the position of the pull block 413. The pull block 413 drives the position of the slide rod 414 to move. The slide rod 414 drives the sealing piston 417 to slide on the inner wall of the rectangular chamber 411. At this time, the lubricant inside the storage chamber 421 will be transported to the inner wall of the rectangular chamber 411 through the one-way valve pipe 416. Then, by lifting the pull block 413, the pull block 413 drives the slide rod 414 to slide on the position of the sealing piston 417. The sealing piston 417 slides on the inner wall of the rectangular chamber 411. At this time, the lubricant will be transported to the inner wall of the output pipe 415 and further enter the inner wall of the high-pressure gate valve body 1 to further lubricate the inside of the high-pressure gate valve body 1.

[0033] Example 2: Based on Example 1, a preferred embodiment of the high-pressure gate valve with lubrication function provided by this utility model is as follows: Figures 1 to 4 As shown: The auxiliary mechanism 42 includes a storage chamber 421, which is fixedly installed on the side wall of the high-pressure gate valve body 1. A feed pipe 422 is fixedly installed on the top of the storage chamber 421, and the side wall of the storage chamber 421 is fixedly connected to one end of the one-way valve pipe 416.

[0034] In this embodiment, a triangular bracket 423 is fixedly installed on the side wall of the storage compartment 421. The side wall of the triangular bracket 423 is fixedly connected to the side wall of the high-pressure gate valve body 1. The stability of the storage compartment 421 can be improved by the triangular bracket 423.

[0035] In the specific implementation process, when the operator uses the high-pressure gate valve body 1, the position of the high-pressure gate valve body 1 can be stabilized by the connecting flanges 2 on both sides of the high-pressure gate valve body 1. Then, lubricating oil can be added to the inner wall of the storage chamber 421 through the feed pipe 422 for storage.
