J961Y-320C power station cut-off valve, power station cut-off valve

Choose different materials, can be applied to water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other media.

I. J941H-16C high temperature steam power station cut-off valve DN150200 Overview:

Power station flange globe valve J941H-16C is composed of two parts: electric actuator and globe valve. The movement form of the valve stem, there are lifting rod type (the valve stem is lifted, the handwheel is not lifted), and there are lifting and rotating rod type (the handwheel and the valve stem are rotated and lifted together, and the nut is located on the valve body). Power station stop valve is only suitable for full open and full close, not allowed to adjust and throttle.

Two, J941H-16C high temperature steam power station cut-off valve cast steel 80 flanged cut-off valve DN150 200 Product features:

(1) Compact structure, reasonable design, good valve rigidity, smooth channel, small flow resistance coefficient.

(2) The sealing surface is made of stainless steel and hard alloy, with long service life.

(3) Flexible graphite packing, reliable sealing, light and flexible operation.

(4) The drive mode is split, electric, pneumatic, gear transmission, structure type: elastic wedge type single ram, rigid wedge type single ram and double ram type.

(5) It is suitable for the opening and closing device for connecting or cutting off the medium in the pipeline of oil and water steam pipelines such as petrochemical industry and thermal power plants.

The selection principle is:

1, high temperature, high pressure medium pipeline or device should choose power station cut-off valve. Such as thermal power plants, nuclear power plants, petrochemical systems of high temperature, high pressure pipelines.

2, the pipeline convection resistance requirements are not strict pipeline. Where the pressure loss is not taken into account.

3, small valve can be selected needle valve, instrument valve, sampling valve, pressure gauge valve, etc.

4, there is flow regulation or pressure regulation, but the regulation accuracy is not high, and the pipe diameter is relatively small, such as the nominal meridian ≤50mm pipeline, should be selected.

5, small chemical fertilizer and large chemical fertilizer in synthetic industrial production should choose the nominal pressure PN160 nominal pressure 16MPa or PN320 nominal pressure 32MPa high-pressure Angle power station cut-off valve or high-pressure Angle throttle valve.

6, alumina Bayer method in the production of desilicon workshop, easy to coking pipeline, easy to choose the valve body separation type, the seat can go, carbide sealing pair of direct flow globe valve or direct flow throttle valve.

7, water supply and heating projects in urban construction, the nominal passage of the smaller pipeline, can choose the cut-off, balance valve or plunder valve, such as the nominal passage of less than 150mm pipeline. The obvious advantage is that during the opening and closing process, the friction between the disc and the sealing surface of the valve body is smaller than that of the power station gate valve. The opening height is generally only 1/4 of the seat channel diameter, so it is much smaller than the power station gate valve. Usually there is only one sealing surface on the valve body and disc, so the manufacturing process is better and easy to maintain.

J961Y-320C power station globe valve is a kind of electric high pressure globe valve, widely used in petroleum, chemical, electric power and other industrial fields, used to control the transmission and distribution of various fluid media. The following are the specific application scenarios:

Petroleum, chemical, hydraulic, thermal power station: suitable for nominal pressure PN20~32MPa and P54/100V-P57/170V, working temperature ≤540℃ (including P57/170V working temperature 570℃) in the pipeline, used to cut off or connected pipeline medium, applicable medium for water, oil, steam, etc.

Boiler cooling water system: J961Y-320C adopts double seal design, using corrosion resistance, temperature resistance metal bellow sealing technology, high temperature and high pressure resistance, long expansion life, can ensure the valve stem leakage, rugged and durable, greatly improve the safety of the system, reduce repair and maintenance costs.

Heat conduction oil system: can be used to cut off or connect the heat conduction oil to the pipeline medium, widely used in petroleum, chemical, pharmaceutical, chemical fertilizer, electric power and other industries in various working conditions on the pipeline
