Description

Technical Field

[0001] This utility model relates to the field of grease injection valve technology, specifically a grease injection valve with a double-safety sealing structure. Background Technology

[0002] In various mechanical equipment, such as oil (gas) well site equipment, ball valves, flat gate valves, and wellhead devices used for oil and gas extraction, it is necessary to lubricate moving mechanical parts in order to reduce mechanical friction and wear. During the grease injection process, a double-safety sealing structure grease injection valve is required.

[0003] Most grease injection valves currently in use have difficulty preventing grease leakage and controlling the discharge speed. During use, difficulty in preventing grease leakage leads to unnecessary grease consumption, increasing operating costs. Leaking grease can also contaminate equipment surfaces, floors, and the surrounding environment, affecting workplace cleanliness and reducing the valve's practicality. Difficulty in controlling the discharge speed can result in excessively fast or slow discharge, leading to excessive grease consumption and waste. It can also cause grease buildup in areas that don't require large amounts of grease, affecting equipment cooling. If the discharge speed is too slow during normal operation and heating, the critical parts of the equipment will not receive timely and sufficient lubrication, which will aggravate the wear of the parts and make the grease injection valve less effective. It will also be more difficult to install and fix the grease injection valve to the grease injection gun. If it is difficult to install the grease injection valve to the grease injection gun during use, it will require a professional or a lot of time to install and fix the grease injection valve to the grease injection gun. Incorrect installation may occur during the process, resulting in an unstable installation and unnecessary waste. Therefore, the grease injection valve is not convenient or secure to install. Utility Model Content

[0004] The purpose of this invention is to provide a grease injection valve with a double-safety sealing structure to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-safety sealing structure grease injection valve, comprising a grease injection valve body, a sealing control mechanism at the bottom of the grease injection valve body, the sealing control mechanism comprising a threaded cylinder, a threaded cylinder at the bottom of the grease injection valve body, a first sealing ring at the bottom end of the threaded cylinder, a fixed cylinder on the outer wall of the threaded cylinder, a threaded opening inside the fixed cylinder, an outlet on the outer wall of the fixed cylinder, and a second sealing ring inside the grease injection valve body.

[0006] As a preferred technical solution, the shape and size of the threaded cylinder match the shape and size of the fixed cylinder, and the fixed cylinder is circular.

[0007] As a preferred technical solution, the outlet is circular in shape, and the number of outlets is three rows.

[0008] As a preferred technical solution, a fixing block is provided inside the grease injection valve body, and a spring is provided on the top of the fixing block.

[0009] As a preferred technical solution, a steel ball is provided on the top of the spring, and the outer wall of the steel ball is in contact with the second sealing ring.

[0010] As a preferred technical solution, the top of the grease injection valve body is provided with a mounting and fixing mechanism, the mounting and fixing mechanism including a mounting plate, and the top of the grease injection valve body is provided with a mounting plate.

[0011] As a preferred technical solution, the mounting plate has mounting holes inside, and the mounting holes are circular in shape.

[0012] As a preferred technical solution, the inner wall of the mounting hole is provided with bolts, and the number of bolts is four.

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

[0014] 1. This utility model, through the setting of a sealing control mechanism, can achieve double sealing of the grease injection valve to prevent grease leakage and control the grease discharge speed. During use, the first and second sealing rings prevent grease leakage. By rotating the fixed cylinder to a suitable position, the number of outlets is controlled, thereby controlling the discharge speed. This avoids unnecessary grease consumption and increased operating costs caused by difficulty in preventing grease leakage. Leaking grease can also contaminate equipment surfaces, floors, and the surrounding environment, affecting workplace cleanliness. This ensures the practicality of the grease injection valve and avoids excessively fast or slow discharge speeds due to difficulty in controlling the discharge speed, resulting in excessive grease consumption and waste. It can also prevent grease buildup in parts that do not require large amounts of grease, affecting equipment heat dissipation and normal operation. Conversely, a slow discharge speed will prevent critical parts of the equipment from receiving timely and sufficient lubrication, accelerating component wear. This ensures the effectiveness of the grease injection valve.

[0015] 2. This utility model, through the setting of the installation and fixing mechanism, can facilitate the installation and fixing of the grease injection valve and the grease injection gun together. During use, the grease injection valve and the grease injection gun are installed and fixed together by the cooperation of bolts and mounting holes. This avoids the situation where it is difficult to install the grease injection valve and the grease injection gun together, which would require professional personnel or spend a lot of time to install the grease injection valve and the grease injection gun together. In such cases, errors may occur during installation, resulting in an unstable installation and unnecessary waste. This ensures the convenience and stability of the installation of the grease injection valve. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Figure 1 and Figure 2 As shown, the present invention provides the following technical solution, including a grease injection valve body 1, a sealing control mechanism 2 at the bottom of the grease injection valve body 1, a fixing block 4 inside the grease injection valve body 1, a spring 5 at the top of the fixing block 4, a steel ball 6 at the top of the spring 5, the outer wall of the steel ball 6 being in contact with the second sealing ring 206, and an installation and fixing mechanism 3 at the top of the grease injection valve body 1.

[0026] When the grease injection valve is needed, the grease injection gun and the grease injection valve body 1 must first be installed and fixed together using the installation and fixing mechanism 3. Then, the lower end of the grease injection valve body 1 is connected to the equipment cavity. The grease injection speed needs to be controlled in advance using the sealing control mechanism 2. Then, grease injection can begin. The grease injection gun injects grease into the grease injection valve body 1. The pressure generated by the grease injection gun acts on the oil injection hole inside the grease injection valve body 1. This pressure overcomes the elasticity of the spring 5 inside the grease injection valve body 1, causing the steel ball 6 to compress the spring 5 and move downward, thereby opening the grease channel. Under pressure, the grease enters the fixed cylinder 203 along the hollow channel inside the grease injection valve body 1 and is discharged through the outlet 205 of the fixed cylinder 203, thus completing the grease injection work. During the grease injection process, the sealing control mechanism 2 provides double sealing for the grease injection valve body 1, and also prevents grease leakage when the grease injection valve body 1 is idle, thus completing the work.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a sealing control mechanism 2 is provided at the bottom of the grease injection valve body 1. The sealing control mechanism 2 includes a threaded cylinder 201. The threaded cylinder 201 is provided at the bottom of the grease injection valve body 1. A first sealing ring 202 is provided at the bottom end of the threaded cylinder 201. A fixed cylinder 203 is provided on the outer wall of the threaded cylinder 201. A threaded port 204 is opened inside the fixed cylinder 203. An outlet 205 is opened on the outer wall of the fixed cylinder 203. A second sealing ring 206 is provided inside the grease injection valve body 1. The shape and size of the threaded cylinder 201 match the shape and size of the fixed cylinder 203. The fixed cylinder 203 is circular. The outlet 205 is circular. There are three rows of outlets 205.

[0028] Specifically: When it is necessary to control the grease injection speed, the fixed cylinder 203 is rotated so that the threaded port 204 inside the fixed cylinder 203 engages with the threaded cylinder 201, causing the fixed cylinder 203 to descend and exposing the outlet 205 on the outer wall of the fixed cylinder 203. The grease injection speed is controlled by the number of exposed outlets 205, thereby completing the control work. During the grease injection process, the first sealing ring 202 and the second sealing ring 206 are used to double seal the grease injection valve body 1 to prevent grease leakage. At the same time, it also prevents grease leakage when the grease injection valve body 1 is idle, thereby completing the sealing work.

[0029] like Figure 1 , Figure 6 and Figure 7As shown, the top of the grease injection valve body 1 is provided with a mounting and fixing mechanism 3. The mounting and fixing mechanism 3 includes a mounting plate 301. The top of the grease injection valve body 1 is provided with a mounting plate 301. The mounting plate 301 has a mounting hole 302 inside. The mounting hole 302 is circular in shape. The inner wall of the mounting hole 302 is provided with bolts 303. The number of bolts 303 is four.

[0030] Specifically: When the grease injection valve is needed, the grease injection gun and the grease injection valve body 1 need to be installed and fixed together. At this time, the mounting plate 301 on the grease injection valve body 1 is aligned with the mounting position of the grease injection gun. Then, the mounting hole 302 on the mounting plate 301 is aligned with the mounting hole 302 on the grease injection gun. Then, the bolt 303 is rotated and inserted into the mounting hole 302 to install and fix the grease injection gun and the grease injection valve body 1, thereby completing the installation and fixing work.

[0031] The working principle of this utility model is as follows: When the grease injection valve is needed, the grease injection gun and the grease injection valve body 1 need to be installed and fixed together. At this time, the mounting plate 301 on the grease injection valve body 1 is aligned with the mounting position of the grease injection gun. Then, the mounting hole 302 on the mounting plate 301 is aligned with the mounting hole 302 on the grease injection gun. Then, the bolt 303 is rotated and inserted into the mounting hole 302 to install and fix the grease injection gun and the grease injection valve body 1, thereby completing the installation and fixing work. Then, the lower end of the grease injection valve body 1 is connected to the equipment cavity. Then, the grease injection speed needs to be controlled in advance. At this time, the fixed cylinder 203 is rotated so that the threaded port 204 inside the fixed cylinder 203 cooperates with the threaded cylinder 201, so that the fixed cylinder 203 is lowered, and the outlet 205 on the outer wall of the fixed cylinder 203 is exposed. The injection speed is controlled by the number of nozzles 205, thus completing the control work. Then, the grease injection can begin. The grease injection gun injects grease into the grease injection valve body 1. The pressure generated by the grease injection gun acts on the oil injection hole inside the grease injection valve body 1. This pressure overcomes the elasticity of the spring 5 inside the grease injection valve body 1, causing the steel ball 6 to compress the spring 5 and move downward, thereby opening the grease channel. Under the action of pressure, the grease enters the fixed cylinder 203 along the hollow channel inside the grease injection valve body 1 and is discharged through the outlet 205 opened in the fixed cylinder 203, thus completing the grease injection work. During the grease injection process, the grease injection valve body 1 is doubly sealed by the first sealing ring 202 and the second sealing ring 206 to prevent grease leakage. It also prevents grease leakage when the grease injection valve body 1 is idle, thus completing the sealing work.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
