Hydraulic shut-off valve overview: Shut-off valve is a commonly used cut-off valve, mainly used to connect or cut off the medium in the pipeline. Globe valve pressure, temperature range, small diameter pipe. The main advantages: simple structure, manufacturing and maintenance are more convenient; sealing surface is not easy to wear, abrasion, sealing better, longer life; opening and closing disc valve stroke is smaller, opening and closing time is shorter, the valve height is smaller. Structural characteristics of the hydraulic cut-off valve: 1, flexible and reliable pneumatic manual conversion mechanism one by one. The pneumatic / manual transfer mechanism mounted on the top of the cylinder head can be easily operated by turning the operating handle at any position during the opening and closing of the shut-off valve, directly from pneumatic to manual or from manual to pneumatic operation Conversion, conversion operation handle positioning pin self-locking design, handle positioning, reliable stabilization. 2, by the solenoid valve and its control circuit or air supply system in case of failure, without other aids, you can quickly switch to manual operation to ensure the normal operation of the line to avoid accidents. 3, before the new construction of the automatic control system is not completed, this series of globe valves can be used reliably as a manual globe valve, the action flexible and brisk. When the valve rotates the handwheel in the clockwise direction, the valve flap is cut off and the channel is closed, and when the valve rotates counterclockwise, the valve is opened. 4, the valve can be divided into pneumatic double-acting and pneumatic normally open and pneumatic normally closed. 5, the working medium should be up under the valve flow (pneumatic in the opposite) 6, the valve can be equipped with electrical or gas back to the device to send the valve switch status information. Therefore, the use of the valve can achieve long-distance control, centralized control and automatic control. 7, the valve of the cylinder used seamless steel pipe manufacturing, corrosion-resistant inner surface plated with hard chromium, and polished, with friction, corrosion, high hardness, long life and other advantages. 8, the cylinder seal with nitrile rubber. Seal ring, sealing performance, maintenance, easy to replace. Hydraulic shut-off valve custody, installation, use and maintenance Note: 1, the valve should be stored in a dry warehouse, the valve must be blocked at both ends of the access road. 2, such as long-term storage should be regularly checked, replace anti-rust oil, and remove the surface dirt and rust. 3, before installation must carefully check the valve logo meets the requirements, check to eliminate dirt, sediment rust and so on. 4, the valve can be installed in any position on the pipeline, but should consider the convenience of maintenance and operation. 5, the media must be consistent with the instructions in the structural description (5). 6, the valve in the safety before the closure of the valve to seal the performance test; valve before installation should also be carried out more than three times the open-close test, the valve spool switch should be flexible, all kinds of shaft should not have jamming phenomenon. 7, the installation is completed to seal test and pneumatic operation test. 5, the valve should be opened to reach the highest position. 6, the process should be kept clean often, the threaded part must be regularly lubricated. 7, found that failure should immediately stop using, identify the cause and eliminate it. 8, the valve in use, should be regularly (18 months) in the cylinder wall filling a small amount of oil. 9, the valve in question should be checked and maintained as frequent as possible. Hydraulic shut-off valve may malfunction and eliminate: 1, the flange connection part of the leak: 2 flange bolts are not tightened or loose uneven, the bolt should be re-opened, evenly tightened. 3 Gasket failure, should be replaced. 3 flange sealing surface between the dirt, should be removed and cleaned. Liquid stop valve packing culvert leakage: 1, the packing is too loose, the packing gland should be evenly compressed. 2, packing circle is not enough, should increase filler. 3, packing gland partial pressure, should be two nuts on the anchor bolt loose again, tighten evenly. 4, filler failure replacement of new packing. Hydraulic shut-off valve closed when the valve leakage treatment: 1, seal abrasion, should be re-processed and grinding, if serious defects should be re-surfacing. 2, sealing surface between the folder of dirt, should be removed to clean. Hydraulic valve stem movement is not flexible: 1 manual / pneumatic reversing handle position error, the reversing handle to switch to the correct position. 2 The packing is too tight and the two nuts on the packing gland should be properly and evenly unscrewed. 3 packing gland pressure bias, the nut should be two new loose bolts loose, tighten evenly. 4 stem and stem nut clip with dirt blocking, or thread contact part of the damage should be removed to clean the hydraulic valve for the pneumatic part of the leakage treatment: 1 cylinder internal O-ring damage, replace the same type O Circle, and add oil. 2 cylinder nut is too loose, should be evenly tightened nuts at both ends of the cylinder. Hydraulic stop valve spring can not be back (single-acting cylinder): 1 Manual / pneumatic reversing handle position error, the reversing handle to switch to the correct position. 2 packing gland is too tight, should be properly loose packing gland.
