The installation and operation is convenient and easy, the gate valve is easy to install, and it can meet the radial tensile force of the pipeline.
This equipment selects metal material casting or composition, and the loose set part selects trapezoidal silicone seal ring, under the effect of screw cap and foot bolt.
Use the basic principle of plastic narrowing elastic deformation. The sealing ring is driven to carry out the packing seal in the middle of deformation of the expansion tube surface of the joint itself.
Metal materials and sealing rings are selected in strict accordance with performance indicators and customer regulations. The raw material is coated with anti-corrosion paint, and each connecting foot bolt is carbon steel or stainless steel plate. Because itself and the expansion tube has a certain gap in the middle, and thus has a certain axial and radial offset.
The compensation in the pipeline and the pushing force of the pipeline and the blind plate can facilitate the installation, maintenance and dismantling of the pump and the gate valve, which is a satisfactory supporting facility commodity in the field of pipeline construction and transportation.
