Welding gate valve opening and closing is plug valve, sealing surfaces appear flat or cone, disc make linear movement along the centerline of fluid. Stem form of exercise, lifting lever ( rod and hand wheel lifting) And lift rotating lever ( Hand wheel rotating lifting with the valve stem and nut in the body) 。 Line pipe cut-off valve is only applicable to all seated, tu do not allow to adjust and throttling. Welding valve, corrugated pipe gate valve, grain tube cut-off valve belongs to compulsory sealed valve, the valve is closed, must be pressure on the disc, to force a sealing surface does not leak. When medium by disc below into the valve 6, the operating force needed to overcome the resistance, is stem and packing friction with the thrust produced by medium pressure, close the Industrial Valves strength is stronger than open the valve, so it's bigger, the diameter of the stem or stem top bending failure happens. From sealed valve, cut-off valve is replaced by the disc above the medium flow direction into the valve cavity, in the medium pressure at this moment, close the valve of the force is small, and the strength of the valve, the Industrial Valves stem diameter can be reduced accordingly. At the same time, in the role of media, this kind of valve is tight. in China 'three for' regulation, the flow of cut-off valve, shall be applied. Welding gate opening, the opening of the disc height, is 25% ~ 30% of nominal diameter, flow has reached maximum, said valve to full open position. So stop valve fully open position, should be determined by disc's schedule. How to prolong the service life of welding gate this is key, and advantage in different types of valves have their applicable specific situation is different, welding valve performance advantage lies in its good sealing, small body is impacted by the fluid pressure and corrosion, let's say how to prolong the life time of the welding of gate valves. One, to ensure that the use of the correct welding gate valve is a kind of forced sealing valve, therefore the globe valve is more superior than welding sealing, but need to close the valve on the disc pressure force, to ensure the sealing surface will not leak. Welding gate is the main purpose of urban gas, heating, heating, fluid exhaust waste steel factories and all kinds of gas heat pipe. Welding gate valves only allow one-way transmission fluid in the pipeline, so welding gate when installation should pay attention to the correct direction, gate valve sealing will reduce after operation for a long time to use, but also by fluid valve surface corrosion and damage, pay attention to the change in time, in order to avoid leakage. Second, completes the daily maintenance of welding gate valve has three, respectively is a right Angle, straight, straight flow cut-off valve, it is best to schedule staff check valve sealing, if there is any leakage and leakage, wear corrosion situation, if the body is severely damaged, there will be less sealing, the ability of fluid under pressure will decrease, so timely maintenance, replacement of new welding gate valves. Welding the service life of the valve is directly related to the quality of the product, and now on the market to make welding gate valve manufacturers have a lot of, the product quality level is also each are not identical, normal manufacturer is a price a points goods, so when the choose and buy must find a reliable manufacturer to order.
