Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting valves, in particular to an instrument pipe fitting valve which is convenient for later maintenance. Background Art

[0002] Pipe fittings and valves are an indispensable part of the pipeline system. They play an important role in regulating, controlling and preventing medium leakage. With the rapid development of my country's petroleum, chemical, electric power, metallurgy and other fields, the pipe fittings and valves industry has also developed rapidly. In the oil industry, pipe fittings and valves are one of the most critical parts of the pipeline. Some important tasks such as oil transportation, oil storage, refueling, packaging, cleaning, etc. need to rely on pipe fittings and valves to complete. In this field, the research on pipe fittings and valves under complex environments such as high pressure, large diameter, ultra-low temperature, ultra-high temperature, corrosion, etc. is one of the current hot spots. In the chemical industry, pipe fittings and valves play an important role in regulating fluid media, protecting the safety of pipeline equipment, reducing losses and improving production efficiency. For different chemical media such as acid, alkali, organic solvents, ammonia, oxygen, etc., pipe fittings and valves need to choose different materials, structures and sealing methods to achieve the best effect. In the power industry, pipe fittings and valves are mainly used for medium flow regulation and control of major equipment such as boilers, steam turbines, dust collectors, air preheaters, etc. Due to the high temperature, high pressure, and large flow characteristics of the power industry, the quality and reliability requirements of pipe fittings and valves are very high, and special materials such as corrosion resistance, high temperature resistance, and wear resistance are required. In short, pipe fittings and valves are widely used in various fields, and their performance and quality directly affect the safety and operating efficiency of the entire pipeline system. With the continuous advancement of technology and the continuous development of the market, the pipe fittings and valves industry will gradually achieve self-renewal and upgrading, and make greater contributions to the development of various industries.

[0003] However, the pipe fitting valves in the prior art still have the following disadvantages:

[0004] 1. Most of the valves in the prior art are integrated, and when they are damaged, they need to be replaced as a whole. The disadvantages include high replacement costs: integrated valves are mostly made by casting or forging, and their costs are relatively high due to the selection of materials and the limitations of manufacturing processes. Therefore, when replacing damaged parts, the entire valve needs to be replaced, resulting in an increase in replacement costs. Inconvenient maintenance: When an integrated valve is damaged or requires maintenance, the entire valve needs to be disassembled, replaced or repaired, and then reinstalled. The maintenance cycle is long, and it is not convenient for on-site operation and maintenance. Not conducive to energy conservation and emission reduction: Once a failure occurs or replacement is required, the entire set needs to be replaced, resulting in a decrease in resource utilization of the original valve, which is not conducive to energy conservation and emission reduction. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the above technical defects and provide an instrument pipe valve which is convenient for later maintenance.

[0006] In order to solve the above problems, the technical solution of the utility model is: an instrument pipe valve that is easy to maintain in the later stage, including: a valve, a connecting pipe, a switch and an anchor bolt; the valve includes a liquid passage groove inside, cavities are provided on both sides of the valve, connecting pipes are provided on both sides of the valve, the connecting pipe includes a tube shell, a clamping plate is provided on the outside of the tube shell, a threaded ring is provided at the front end of the tube shell, and the clamping plate is embedded in the cavity for fixed connection.

[0007] Furthermore, the valve is connected to a switch, which includes a spherical blocking block. A connecting shaft is provided above the spherical blocking block, the connecting shaft is fixedly connected to the spherical blocking block, and the upper end of the connecting shaft passes through the valve.

[0008] Furthermore, a rotating disk is provided at the upper end of the connecting shaft, and the rotating disk is fixedly connected to the connecting shaft.

[0009] Furthermore, an anchor bolt is provided above the valve, and the connecting pipe is connected to the valve via the anchor bolt.

[0010] The advantages of the utility model compared with the existing technology are:

[0011] 1. The utility model valve adopts an assembled structure, which can replace individual parts. This has the advantages of cost saving: the assembled structure valve can disassemble the entire valve into multiple independent parts. When a part is damaged or needs to be replaced, only the part needs to be replaced, and the entire valve does not need to be replaced. This can greatly reduce the replacement cost and reduce waste. Convenient maintenance: the assembled structure valve can maintain each part separately. When a part needs to be repaired or replaced, only the part needs to be operated without affecting the normal operation of other parts. This can improve the efficiency of maintenance and reduce downtime. Environmental protection and energy saving: the assembled structure valve can make full use of the original parts. When a part needs to be replaced, it can be repaired or reused, reducing the waste of resources. At the same time, since only specific parts are replaced, there is no need to replace the valve as a whole, which also reduces energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS
