Opening and closing a gate valve is ram, ram movement direction perpendicular to the direction of flow, gate valve can only be fully open and close, not to adjust and throttling. Gate valves also has a good variety of classification. According to the material can be classified as cast iron gate valves, cast steel gate valves, stainless steel gate valve and so on. According to the transmission mode can be divided into manual gate valves, electric gate valves, pneumatic Industrial Valves, etc. According to the mode of connection can be divided into flange gate valve gate valves, welding, etc. Flanged gate valve has the following advantages: 1, small fluid resistance, sealing surface Chong brush and erosion by the medium. 2, open and close more effort. 3 the flow direction of medium, not restricted, disturbed flow, reduce the pressure. 4, the structure of the form is simple, short length, good manufacturing technology, wide application scope. Flanged gate Industrial Valves faults as follows: 1, easy cause erosion and abrasion, surface maintenance more difficult. 2, appearance size is larger, open needs certain space, open and close time is long. 3, the structure is complex. Flanged gate valve installation and maintenance should be paid attention to the following: 1, hand wheel, lever and transmission mechanism are not allowed for lifting, and it is forbidden to collision. 2, double disc gate valves should be installed vertically ( The stem in a vertical position, the handwheel at the top) 。 3, with a bypass valve gate valve in open open the bypass valve should be taken before, To balance the import and export of pressure difference and reduce the opening force) 。 4, belt transmission mechanism of the gate, according to the regulations of the product instruction manual installation. 5, if the valve switch is used, often lubrication at least once a month.
wedge gate valve has become a standardized way of dealing with os&y valve.
