The safety valve is one of the three indispensable safety accessories on the boiler. It plays an important role in the control of the internal pressure limit of the boiler and the safety protection of the boiler.…

The safety valve is a kind of overpressure protection device. When the pressure in the equipment, container or pipeline exceeds the allowable value, the valve will automatically open and then discharge all to prevent the pressure in the equipment, container or pipeline from continuing to rise; when the pressure drops to the specified value When the value is reached, the valve will automatically cl…

Its plug can be cylindrical or conical. In cylindrical plugs, the channels are generally rectangular, while in tapered plugs, the channels are trapezoidal. These shapes make the structure of the plug valve lighter.…

The advantage of plug valve application is that the valve body installed on the top of the whole is equivalent to the ball valve installed on the top of the whole. Compared with two-piece or three-piece ball valve, it is a completely different type and application product.…

The plug valve is mainly used for cutting off, upgrading and changing the flow direction of the medium in the pipeline. It is easy to adapt to a multi-channel structure, so that one valve can obtain two, three, or even four different flow channels, which can simplify the design of the piping system, reduce the amount of valve gates and some connection accessories required in the equipment.…

Tight-sleeve plug valve The tight-sleeved plug valve is usually used in low-pressure straight-through pipelines. The sealing performance depends entirely on the fit between the plug and the plug body. Compress the sealing surface by tightening the lower nut. Generally used for PN≤0.6MPa.…

Eccentric plug valve is also called flexible cam valve and eccentric ball plug control valve. When the control valve approaches, it has an eccentric rotating spool. When the valve is closed, the bent arm of the valve core is deformed, so that the spherical ball plug of the valve core is in close contact with the valve seat, and the sealing performance is very good.…
