The difference between electric ball valve and electric ball valve The difference between electric ball valve and electric ball valve is that the gland type electric ball valve adds the equipment of limit device on the basis of electric ball valve, and uses double nuts for locking at large expansion and contraction. The advantage of this is that when the expansion and contraction of the pipeline exceeds the specified standard during operation, it can immediately play a limiting role, The utility model can effectively ensure the safe operation of the pipeline, and is especially suitable for connection in the pipeline with vibration or slope. The use of the gland type electric ball valve can effectively prevent the leakage and damage of the compensation joint caused by excessive displacement during the use of the pipeline. During installation, first loosen the gland nut, then adjust it to a suitable length, weld the short pipe at both ends with the pipeline, and finally tighten the nut to prevent the nut from falling off. The gland type electric ball valve has good comprehensive performance and is widely used in chemical, construction, petroleum, health and other basic projects.
Electric ball valve is a new type of pipe connector developed by our factory on the basis of absorbing foreign advanced technology and combining actual needs. The product structure is designed reasonably and the sealing performance is reliable; Both ends adopt socket connection, which is convenient for installation and disassembly. It is suitable for connecting steel pipes, cast iron pipes, ductile iron pipes, PAC pipes, ABS pipes, etc. that transport water, oil, gas and particulate matter. When connecting, it can compensate the axial displacement of the pipes and a certain amount of deflection and eccentricity.
