Flexible waterproof casing shall be used in the fire pool. Because the equipment has a certain function of preventing water from seeping, flowing and flowing to the lower layer, the "prevention" here has two aspects: on the one hand, it refers to that after the completion of the project, the user, during the decoration stage, causes the running water to flow through the casing pipe to the lower layer due to improper reasons; On the other hand, after the user enters the station, the accident causes the running water to flow through the casing to the lower layer, and the former is often more than the latter. When the rigid waterproof sleeve passes through the pipeline or other cables, it needs to be plugged into the gap with jute and other sealants. The sealing performance is poor, and it cannot be used in the flexible waterproof sleeve with high sealing requirements. Because it has a closed wing ring and a protective resistance plate, it should be treated carefully when the pipeline passes through the closed partition wall. Reserved holes are not allowed, Tonghua flexible valve electric ball valve has been imitating the casing expansion joint, which is composed of inner and outer casing that can make axial relative movement.
The stuffing box is used for sealing between the inner and outer casings. Keep the tubes at both ends moving on the same axis during use. The product is mainly composed of sleeve (core tube), shell, sealing material, etc. It is used to compensate for the axial expansion and contraction of the pipe and the axial rotation at any angle. It has the characteristics of small volume and large compensation amount, and is suitable for hot water, steam, grease and other media. The sliding movement of the outer sleeve through the sliding sleeve can compensate for thermal expansion.
Electric ball valve is also called valve electric ball valve, flexible electric ball valve, flexible electric ball valve, valve shock absorber, etc. The product is mainly composed of tubular valve parts composed of inner and outer rubber layers, cord layers and steel wire rings, which are vulcanized at high temperature and high pressure and then combined with metal flange loose sleeves. It is widely used in fire protection, chemical industry, pump valve and other pipeline systems, playing the role of earthquake resistance and noise reduction, and absorbing the displacement generated during pipeline operation. Electric ball valve is a hollow valve product used for flexible connection between metal pipes. Electric ball valve is also called valve pipe electric ball valve, flexible electric ball valve, valve electric ball valve, flexible electric ball valve, high pressure electric ball valve, valve shock absorber, etc.
