Description

Intelligent flat valve integrated with built-in pressure detection rod Technical Field The invention relates to the technical field of flat valves, in particular to an intelligent flat valve integrated with a built-in pressure detection rod. Background The plate valve is used as a common fluid control device and is widely applied to the fields of petrochemical industry, natural gas transportation, hydraulic engineering, pressure vessels and the like, and has the main functions of realizing the isolation and circulation of fluid by controlling the on-off of a medium channel through a valve plate. In the industrial production and equipment pressure test process, the reliability and the sealing performance of the flat valve are of vital importance, and particularly, in the occasion of high pressure, high temperature or corrosive medium, the fluid pressure in the valve body needs to be strictly monitored so as to ensure the safe operation of the equipment and meet the related standard requirements. In the prior art, pressure detection mainly depends on external additional equipment, such as a pressure gauge, a pressure sensor or a temporary access pressure test instrument, which are additionally arranged on a pipeline. This method requires the operator to shut down, disassemble the valve flange, or break the seal prior to inspection to access the inspection device. This process is time consuming and labor consuming, increases production downtime costs, and is also prone to introducing secondary leakage risks, especially in high pressure or corrosive medium environments where seal failure may lead to safety accidents. More importantly, existing integrated pressure sensing designs (e.g., incorporating a sensor directly into the valve body) tend to ignore hydrodynamic effects. When the valve is opened, high-speed fluid in the medium channel can impact a fixed detection element (such as a pressure probe or a sensing rod) strongly, so that the element is deformed, worn or even broken. Especially under the working condition of high pressure difference, the mechanical damage not only shortens the service life of the detection device, but also can cause cascading failure due to pollution of fluid by element fragments or blockage of channels. Meanwhile, the existing system lacks intelligent data processing capability, pressure data usually depends on manual reading and recording and cannot be automatically uploaded to a central control system, and a detection report needs to be manually compiled, so that data traceability is poor. Therefore, there is a need for an intelligent flat valve that integrates a built-in pressure sensing stem to at least partially address the problems of the prior art.
