Various Packing Applications

1.Valve

Usually installed between the valve core and the valve seat, it plays the role of sealing and fixing the valve core. When the valve is closed, the packing can fit tightly with the valve seat to prevent medium leakage and ensure safety in production or life.

Sealing function: The sealing performance of the valve is closely related to the quality and installation status of the packing. The better the sealing performance of the packing, the higher the sealing performance of the valve. When the valve is closed, the packing can fit tightly with the valve seat to prevent medium leakage and ensure safety in production or life.

Function of fixing the valve core: Packing can also fix the valve core to prevent it from loosening or falling off during use, and ensure the switching performance of the valve. Therefore, installing packing can not only extend the service life of the valve, but also reduce the number of maintenance and replacement, and reduce costs.

Balance adjustment function: Packing can also be used to adjust the preload of the packing spring to balance the expansion and deformation of the valve under high temperature and high pressure environment, thereby maintaining the stability and normal operation of the valve.

2.Pump

Connection function: It has a certain plasticity, can generate a certain radial force under the action of compression force and contact with the tight shaft.

Sealing function: It has sufficient chemical stability, does not pollute the medium, the filler is not swollen by the medium, the impregnating agent in the filler is not dissolved by the medium, and the filler itself does not corrode the sealing surface. The filler has good self-lubricating properties, wear resistance, and a small friction coefficient.

Supporting function: When the shaft has a small amount of offset, the packing should have sufficient floating elasticity. Simple manufacturing and convenient filling

3.Reactor

When using packing seal structure in reactor, the selection of packing is also very important. Different media require different packing materials. As a reliable sealing form, packing seal structure will have a wide range of application prospects in equipment such as reactor.

4.Ship tail shaft equipment

Packing is an important component that connects the tail shaft sleeve and the propeller shaft. Its function is to make the torque transmission between the tail shaft and the propeller shaft smoother and reduce friction and vibration. At the same time, the packing can also play a role in waterproofing and sealing.

5.High temperature pipes, furnace doors, etc.

Packing is used for high temperature flue, air duct bushing, expansion joints, and plays a role in high temperature heat insulation and heat preservation. It has a very good sealing effect and is not prone to leakage. It is used in the door seals and furnace curtains of various heat-insulating industrial kilns.
