Description
Technical field
The utility model relates to the instrument and meter for automation field, specifically a kind of shock-proof pressure gauge.
Background technology
Existing tensimeter generally comprises watchcase and the glass face that covers on the described watchcase, is provided with nipple in the watchcase, and the afterbody of nipple stretches out outside the watchcase, and watchcase is provided with coupling outward, and coupling is threaded with nipple.Yet a lot of operation occasions have bigger vibrating effect, and perhaps some big machineries have bigger seismaesthesia, and at this time general tensimeter just can't adapt to this situation, use the ordinarily manometer might the damage of build-up of pressure table, the serious work accident that causes.
The utility model content
The technical problems to be solved in the utility model is to overcome existing defective, and a kind of shock-proof pressure gauge is provided, the environment that can the shock adaptive amplitude strengthens.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of shock-proof pressure gauge, comprise watchcase, glass face, joint, O-ring seal, crimping cover circle and explosion-proof plug, described joint comprises nipple and coupling, be provided with nipple in the described watchcase, the afterbody of described nipple stretches out outside the described watchcase, described watchcase is provided with coupling outward, and described coupling is connected with described nipple; Described O-ring seal comprises ring-like O-ring seal and channel gasket, and the outer rim of described glass face is arranged with channel gasket, connects by crimping cover snare between described glass face and the described watchcase; Offer oil-filled mouthful on the described watchcase, described oil-filled mouthful of top plug is provided with explosion-proof plug, is filled with damping fluid in the described watchcase.
Further, be provided with ring-like O-ring seal between the inwall of described nipple and described watchcase.
Further, described coupling is threaded with described nipple.
Further, described damping fluid is silicone oil or glycerine.
A kind of shock-proof pressure gauge of the utility model, be applicable to the violent oscillator field of environment institute, can tolerate the medium pulsation, impact and unexpected off-load, it is clear that the instrument indication is stablized, and is widely used in machinery, departments such as oil, chemical industry, metallurgy, mine, electric power, measurement is made simply the pressure of copper and copper alloy non-corrosiveness medium, is easy to large-scale promotion.
