Problems solved by technology

[0003] At present, the instruments of instrument valves used in dark environments generally do not have protective devices. Therefore, external environmental factors will directly affect the instruments. After a long period of action, the instruments will be damaged and cannot be used.
In addition, the meter has no lighting measures in the dark environment, which makes it very troublesome for the meter reader to read the meter

Abstract

The invention discloses a protection device for an instrument valve and instrument, which comprises an instrument valve body and an instrument connected with the instrument valve body. One end of the fixed rod is fixed to the top of the instrument valve body, and the other end of the fixed rod is fixed with a protective case with one side opening, the instrument is located inside the protective case, and the side of the protective case away from the opening is fixed with a fixed block, so A limiting rod is fixed on the top of the fixing block, and a connecting rod is arranged between the limiting rod and the protective case, and a connecting column is fixed on one side of the connecting rod. The present invention not only prevents the dust from covering the meter, but also protects the meter by using the push button, connecting column, connecting rod, connecting cover, slide plate and protective shell, and prevents the meter from being directly damaged by external factors, so that the meter longer service life.

Description

technical field [0001] The invention relates to the technical field of instrument devices, in particular to a protection device for instrument valves and instruments. Background technique [0002] An instrument valve is a pipeline accessory. It is a device used to change the passage section and medium flow direction, and control the flow of conveying medium. The sealing performance of the instrument valve refers to the ability of each sealing part of the instrument valve to prevent the leakage of the medium, which is the most important technical performance index of the instrument valve. There are three sealing parts of the instrument valve: the contact between the opening and closing parts and the two sealing surfaces of the valve seat; the matching place between the packing and the valve stem and stuffing box; The first one is called internal trickle, also known as sleek close, that can affect the capability of device to reducing medium. For cut-off valves, internal lea...
