Description

A kind of corrosion-resistant high pressure exceeds the automatic pressure-reducing instrument
Technical field
The utility model relates to the field of the instrument that reduces pressure, and especially a kind of corrosion-resistant high pressure exceeds the automatic pressure-reducing instrument.
Background technique
The decompression instrument is by regulating, inlet pressure is reduced to the outlet pressure of a certain needs, and the energy of dependence medium itself, make outlet pressure automatically keep stable instrument, from hydromechanical viewpoint, the decompression instrument is the element of the local resistance throttling that can change, by changing orifice size, the kinetic energy of flow velocity and fluid is changed, cause the different pressure losses, thereby reach the purpose of decompression.Then rely on the adjusting of controlling with regulating system, the fluctuation of downstream pressure and spring force are balanced each other, make downstream pressure keep constant in certain margin of error.
The decompression instrument that uses at present, be all to adopt manual tune,, due in adjustment process, causes easily that strength of adjustment is inadequate or strength of adjustment is excessive, damages regulator, thereby cause the damage of decompression instrument.
Summary of the invention
The technical problems to be solved in the utility model is:, in order to overcome the problem of above-mentioned middle existence, provide a kind of corrosion-resistant high pressure to exceed the automatic pressure-reducing instrument, its project organization is reasonable, automaticity is high, easy to adjust, corrosion resistance is strong.
the technological scheme that its technical problem that solves the utility model adopts is: a kind of corrosion-resistant high pressure exceeds the automatic pressure-reducing instrument, comprise decompression instrument body, be connected to admission line and the outlet pipe of decompression instrument body both sides, be communicated with boost gauge on admission line, be communicated with the pressure gauge of giving vent to anger on outlet pipe, on described decompression instrument body, the automatic Regulation valve assembly is installed, the automatic Regulation valve assembly is communicated with between admission line and outlet pipe, described automatic Regulation valve assembly comprises the PLC controller, electric valve, pressure transducer, electric valve and pressure transducer are arranged between admission line and outlet pipe, pressure transducer is located at electric valve the place ahead, the PLC controller is connected with electric valve with pressure transducer respectively.
The inner-wall spraying of described admission line and outlet pipe has corrosion-resistant coating.
Described corrosion-resistant coating is the polyurea anti-corrosion coating, and polyurea coating has the protective value of acid-and base-resisting, salt solution and anti-petroleum product, and coating adhesion is high, the characteristics that antikathode stripping property and permeability are good and wear resistance is good.
The beneficial effects of the utility model are: described a kind of corrosion-resistant high pressure exceeds the automatic pressure-reducing instrument, and the automatic pressure regulator component design on the decompression instrument, can be realized the flow of automatically controlling air inlet and giving vent to anger, and automaticity is high, and is easy to use.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the overall structure schematic diagram that a kind of corrosion-resistant high pressure described in the utility model exceeds the automatic pressure-reducing instrument;
