BJ41W Insulation globe Valve Product Introduction:
In the process of opening and closing, the friction between the sealing surface is small, more durable, the opening height is not large, easy to manufacture, convenient maintenance,not only for medium and low pressure, but also for high pressure. Its closing principle is to rely on the pressure of the valve lever to make the sealing surface of the valve disc closely fit with the sealing surface of the valve seat to prevent the flow of the medium.
Product implementation standards:
1) Design and manufacture: BS1873BS5160GB12233
2) Flange size: ANSIB16.5JB/T79GB9113
3) Pressure temperature: ANSIB16.34
4) Structure length: ANSIB16.10BS1873GB12221
5) Butt welding connection size: ANSIB16.25
6) Test and experiment: BS6755GB/T13927
Product working principle:
The opening and closing part is a plug shaped valve disc, the sealing surface is plane or cone, and the valve disc moves in a straight line along the center line of the fluid. The movement of the valve stem has a lifting rod type (the valve stem is lifted, the handwheel is not lifted), and a lifting rotary rod type (the handwheel is rotated with the valve stem, and the nut is located on the valve body). Applicable only to fully open and fully closed, not allowed to adjust and throttle. It has the characteristics of heat preservation and cold preservation, and is suitable for petroleum, chemical, metallurgy, pharmaceutical and other industries. It is suitable for the pipeline of chemical industry and fertilizer industry, and the steam in the jacket can prevent the crystallization of the medium.
Product use:
It is mainly used in petroleum, chemical, metallurgical, pharmaceutical and other systems to transport high-viscosity media that will solidify at room temperature.
BJ41W Insulation globe valve design features:
Advantages:
Simple structure, convenient manufacture and maintenance.
Small working trip, short opening and closing time.
Good sealing, small friction between sealing surfaces, long life.
Cons:
The fluid resistance is large, and the force required for opening and closing is large.
Not suitable for media with particles, high viscosity and easy coking.
The adjustment performance is poor.
Product use:
It is mainly used in petroleum, chemical, metallurgical, pharmaceutical and other systems to transport high-viscosity media that will solidify at room temperature.
Packing of Standard Packing:
Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 470 gallon liquid totes Special package is available on request.
