GSR stainless steel valve failure are: can't reverse or reversing action is slow, gas leak, such as electromagnetic pilot valve has some problem. ( 1) GSR reversing valve cannot reversing or reversing slow, usually because of bad lubrication, spring stuck or damage, oil or impurity sticking sliding part and other causes. To this, should first check of oil mist is normal; The viscosity of the lubricating oil. When necessary, should replace lubricating oil, cleaning sliding part of the directional control valve, or replace spring and directional control valve. ( 2) GSR directional control valve is seen after long time use the sealing ring wear, the valve stem and valve core seat damage phenomenon, lead to gas leakage in the valve, valve slow or can't normal commutation failure, etc. At this point, a seal, valve stem and seat should be replaced, or will the reversing valve. ( 3) If GSR electromagnetic pilot valve inlet and vent was sludge and other debris jam, closed lax, activity core was jammed, a fault circuit, etc. , all can lead to directional valve can't normal commutation. The former three kinds of activities should be cleaning pilot valve and core on the sludge and impurities. And circuit fault generally divided into two groups: the control circuit fault and electromagnetic coil. GSR stainless steel valve in the test circuit before failure, reversing valve first hand knob turning a few times, see if the reversing valve under the rated pressure can normal commutation, if can normal commutation, circuit is defective. Check, instrument measuring electromagnetic coil voltage are available, and see if the rated voltage, if the voltage is too low, should further check the control circuit of the power supply circuit and associated travel switch. If under the rated voltage directional valve can't normal commutation, should check the joint of electromagnetic coil ( Plug) Whether loose or exposure to false. Method is to remove the plug, measuring coil resistance, if the value is too big or too small, and explain the electromagnetic coil is damaged, should be replaced. GSR stainless steel valve material quality enhancement in turn. GSR stainless steel valve industry: food biscuits industries, instant noodles and rice noodles, a variety of quick-frozen food dehydration assembly line equipment, glass products industry. Can be used to control air, water, steam, all kinds of corrosive medium, mud, oil, liquid metal and radioactive medium such as various types of fluid flow. GSR stainless steel valves are widely used in chemical, petrochemical, petroleum, the papermaking, mining, electricity, liquid gas, food, pharmaceutical, water supply and drainage, municipal, mechanical equipment, electronic industry, urban construction and other fields. is control unit in the pipeline fluid conveying system, it is used to change the channel cross-section and flow direction of medium, a diversion, globe, adjust, throttle, check, or the overflow pressure relief, and other functions. Used for fluid control valve, from the most simple cut-off valve to extremely complex automatic control system used in all kinds of valves, its various varieties and specifications. GSR stainless steel valves can be used to control water, steam, oil, gas, mud, all kinds of corrosive medium, liquid metal and radioactive fluids such as various types of fluid flow, the Industrial Valves working pressure can be from 0. Ultra-high pressure 0013 mpa to 1000 mpa, from operating temperature Ultra-low temperature of 269 ℃ to 1430 ℃ high temperature. GSR stainless steel valve installation 1, GSR valve lifting, don't fastened on the hand wheel or valve stem, in order to avoid damage to these parts, should wear on the flange. 2, before the installation, should be GSR make a check valve, check specifications, identification with and without damage, especially for the valve stem. Must turn a few times, look to whether skewed, because in the process of transportation, the most easy to break the valve stem. To remove debris within the valve. 3, installation of pneumatic valves, flange bolt must pay attention to the symmetrical evenly. The valve flange and pipe flanges must be parallel, clearance is reasonable, in order to avoid too much pressure valve, and even cracking. For brittle material and the valves of strength is not high, especially pay attention to. Valves and pipe welding, should first spot welding, will close a full open again, and then welding die. 4, install screw GSR valve, sealing packing (should be Cotton and ramie thread woven with lead or ptfe teflon tape) On pipe threads, package, don't get into the valve, in order to avoid the memory product, medium circulation. 5, for GSR valves is connected line, must be clean. Can use compressed air to blow to clay sand, iron oxide, slag and other sundry. These stuff, not only easy to scratch the valve sealing surface, the larger particles of sundry, can also be closed small valves, disable it.
