Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a highly airtight T-type valve with a mechanical interlocking mechanism. Background Art

[0002] Valves are pipe accessories used to open and close pipes, control flow direction, and adjust and control the parameters of the conveyed medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems and have functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief. Valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest shut-off valves to various valves used in extremely complex automatic control systems.

[0003] After searching, the existing patent (publication number: CN217463323U) discloses an adjustable linkage T-type valve, including a main pipe and an adjustment component, an adjustment component for adjusting the flow is arranged below the main pipe, and the adjustment component includes a drive motor, a drive shaft, a first gear, a second gear, a self-rotating block, a threaded rod and a stop block. A drive shaft is arranged in the middle of the upper part of the drive motor, and a first gear is arranged at the top of the drive shaft. The outer wall of the first gear is meshed and connected with the second gear. The second gear is provided with a self-rotating block near the main pipe. A threaded rod is arranged through the middle of the second gear and the self-rotating block, and the stop block is fixedly connected to the top of the threaded rod. The adjustable linkage T-type valve can achieve the purpose of automatically adjusting the gas flow through the adjustment component, so that the staff can conveniently adjust the gas flow, increase the convenience of the device itself, and at the same time, it is also extremely convenient in installation, and its own connection is sealed to ensure air tightness.

[0004] However, the existing high-tightness T-type valve with a mechanical interlocking mechanism has a high leakage rate during operation, and valve tightness is the key to evaluating valve performance. Therefore, when the valve leakage rate is high, leakage hazards are likely to occur, which will greatly reduce the practicality of the T-type valve.

[0005] Therefore, in order to solve the above problems, a T-type valve with high airtightness and a mechanical interlocking mechanism is proposed. Utility Model Content

Therefore, when the valve leakage rate is high, leakage hazards are likely to occur, which will greatly reduce the practicality of the T-type valve.
