GSR stainless steel valve failure are: the valve can not be commutated or reversing action is slow, gas leakage, electromagnetic pilot valve failure and so on. (1) GSR ​​reversing valve can not change direction or change slowly, usually due to poor lubrication, spring is stuck or damaged, oil or impurities stuck sliding parts and other causes. In this regard, should first check the work of the oil mist is normal; the viscosity of the lubricant is appropriate. If necessary, lubricate, clean the sliding part of the reversing valve or replace the spring and reversing valve. (2) GSR ​​reversing valve prone to valve plug seal wear after a long period of use, the valve stem and valve seat damage, leading to gas leakage in the valve, the valve movement is slow or can not be the normal commutation and other failures. At this point, the seals, stem and seat should be replaced or the reversing valve replaced. (3) If GSR electromagnetic pilot valve inlet and exhaust holes are clogged with debris such as sludge, closed laxity, the activities of the core is stuck, the circuit is faulty, etc., can lead to the reversing valve can not be reversed. For the first 3 cases, clean the sludge and impurities on the pilot valve and movable iron core. The circuit failure is generally divided into two types of control circuit failure and electromagnetic coil failure. GSR stainless steel valve check circuit failure, the first manual valve knob turn a few times to see whether the reversing valve in the normal pressure under normal commutation, if the normal commutation, the circuit is faulty. Check, the instrument can measure the voltage of the solenoid to see if it has reached the rated voltage, if the voltage is too low, you should further check the control circuit power and the associated trip switch circuit. If the reversing valve can not be changed normally under the rated voltage, check whether the electromagnetic coil connector (plug) is loose or inaccurate. Method is, unplug the plug, measuring the resistance of the coil, if the resistance is too large or too small, indicating that the electromagnetic coil is damaged, should be replaced. GSR stainless steel valve material quality in turn enhanced. GSR stainless steel valves using the industry: food biscuit industry, instant noodles and rice noodles industry, all kinds of frozen food dehydration line equipment, glass products industry. Can be used to control the air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media, and other types of fluid flow. GSR stainless steel valves are widely used in chemical, petrochemical, petroleum, papermaking, mining, electricity, liquefied petroleum gas, food, pharmaceuticals, water supply and drainage, municipal services, machinery and equipment supporting, electronics industry, urban construction and other fields. The valve is a control component in the pipeline fluid delivery system. It is used to change the cross section of the pipeline and the flow direction of the medium. It has the functions of diversion, cut-off, regulation, throttling, checkback, shunt or overflow pressure relief. Valves for fluid control range from the simplest shut-off valves to the wide range of valves used in the most sophisticated automation systems. GSR stainless steel valve can be used to control the flow of various types of fluids such as water, steam, oil, gas, mud, all kinds of corrosive medium, liquid metal and radioactive fluid. The working pressure of valve can be ultra high pressure from 0.0013MPa to 1000MPa, Operating temperature from -269 ℃ ultra-low temperature to 1430 ℃ high temperature. GSR stainless steel valve installation 1, GSR valve lifting, the rope should not be tied to the hand wheel or stem, so as to avoid damage to these components, should be tied to the flange. 2, Before installation, GSR valve should be checked, check the specification model, identification of damage, especially for the valve stem. Also a few turns to see if it is skewed, because the transport process, the most likely to crash crooked stem. Also remove the debris inside the valve. 3, install the flange pneumatic valve, pay attention to symmetry evenly to the bolt. Valve flange and pipe flange must be parallel, the gap is reasonable, so as to avoid excessive pressure on the valve, and even cracking. Pay special attention to brittle materials and valves with low strength. To be welded with the pipe valve, the first spot welding, and then close the full-open, and then welded to death. 4, Install screw GSR valve should be sealed packing (Ma Ma plus lead or Teflon raw material tape), wrapped in the pipe thread, do not get the valve, so as to prevent the accumulation of the valve, affecting the flow of media. 5, for GSR valve connected to the pipeline, be sure to clean. Available compressed air to blow sand, iron oxide dust, welding slag and other debris. These debris, not only easy to seal the sealing surface of the valve, including large particles of debris, but also blocked small valves, so that failure.
