For vulnerable to snow and rain, dust and sand storm, from the background of electric valve, the valve stem to install try our best to take care of. ( 2) Stem and stem nut of ladder type turnbuckle wear condition. Don't allow the person pounding, standing on the running of electric valve or bearing weight; Matters and especially the metal electric valves and cast iron electric valve, it is strictly prohibited. Flange turnbuckle and screw on the stent is necessary, turnbuckle should be intact, a relaxation phenomenon is not allowed. Q: which is specialized in the produce of electric valve? Answer: the valve is the valve, electric head is electric head, is a professional factory of ordinary valve manufacturers are not producing electric head, ordinary valves can be installed electric head, so produce professional electric valve manufacturers is more power! Electric Industrial Valves, in a nutshell is to use the electric actuator. Stem valves, so the successful implementation and off of the valve. The Marine valve rod on electric valves should keep complete, correct and clear. Tighten nut on the wheel, such as find relaxation should tighten early, lest abrasion petition or throw not seize the wheel and metal sign. Warm jacket should be no visible for inside, crack. ( 3) Packing is stale lose effectiveness, if there is any damage should change early. Strengths: the liquid medium and large diameter gas effect is good, is not affected by climatology. ( 4) After check the repair of electric valve assembly, should try imposed tight sealing performance. Protection of electric valve protection and nurse 1 at ordinary times should be save dry ventilated room, electric valve, on both ends of the channel must be congestion. Is not affected by air pressure of dying. The packing gland skewed or no preloaded gap is not allowed. The running of electric Industrial Valves, all kinds of valve parts should be everything, in good condition. 3, after the installation, should be regularly seizing, main investigation project: ( 1) Tightly closed surface abrasion conditions. It can be divided into two local, local to the upper electric actuators, the second half of the local for the valve. The seal of electric valve, blocked shots, pneumatic accessories, etc. Everything should be in good condition. Missing: high cost, in moist background is very bad. 2, long period storage place of electric valve should crack down on a regular basis, cleaning, and utterly dirt, and rust-proof oil coating on the surface of the processing. The handwheel is lost, not allowed to use the board to replace, should be complete early. 。 Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
