Technical Field

The invention relates to a locking structure for mounting and fixing various pressure gauges and quickly obtaining angular positioning, which is widely applied to gas and liquid pipeline systems, and is particularly suitable for observing and measuring the pressure value of a specific point of the gas and liquid system.

Background

Pressure gauges (pressure gauge) are instruments that measure and indicate a pressure above ambient, using an elastic element as a sensing element. The pressure gauge transmits pressure deformation to the pointer through elastic deformation of a sensitive element in the gauge and a conversion mechanism of a movement in the gauge, so that the pointer rotates to display pressure. The application of the pressure gauge almost extends to all industrial processes and scientific research fields, and is widely seen in the fields of heat pipe networks, oil and gas transmission, water and gas supply systems, vehicle maintenance factories and stores and the like. Especially in the industrial process control and technical measurement process, the mechanical pressure gauge is more and more widely applied due to the characteristics of high mechanical strength, convenient production and the like of the elastic sensitive element of the mechanical pressure gauge. The safety net of the input interface circulation pipeline of the inspection pump usually needs to inspect the pressure gauge at any time, find whether there is damage, and replace the pressure gauge in time. When the pressure gauge is installed, the threaded installation head is usually screwed at the end of the pipeline matched with the threaded installation head, and the inner cavity of the pipeline is communicated with the inner cavity of the pressure gauge. This type of connection is inconvenient when reading a meter, because the pressure gauge must be screwed to the pipe port, otherwise there will be leakage, when the pressure gauge is screwed, the face of the pressure gauge is uncertain, sometimes it may face to the side that is difficult to observe, causing trouble to the meter reading. Sometimes, a meter reading person rotates the dial plate by a certain angle slightly, so that the dial plate is loosened and possibly leaks when the meter is read conveniently. Pressure gauges which are not convenient to disassemble on site in various gas and liquid systems also relate to observation and recording of system pressure values at a plurality of specific points so as to acquire corresponding data. Along with the access of some pressure gauges on pipelines, how to quickly access the pressure gauge on the pipeline, and can obtain stable and reliable sealing and obtain an easily observed pressure surface angular direction is a problem which cannot be ignored, and unnecessary obstacles and troubles are brought to the whole system due to the fact that a good observation surface is not provided and the connection is not good. The pressure gauge is usually sleeved on the pipeline support in a hollow mode through a hexagonal nut, one side of the pressure gauge, which needs to be connected with the pressure gauge, is convenient to connect the pressure gauge in a screwing mode from the lower end, and the pipeline support is installed on an observable point through a connecting screw. However, how to apply the screw-locking directional pressure gauge and increase the angle of the observable surface of the pressure surface is a relatively difficult problem.
