。 The principle: plunger as of valve by Industrial Valves body, valve cover, gland, valve stem, valve plug, plug cover, piston ring and cylinder liner ( The seat) Rising stem nut, the simplest surface bearing, wheel, bevel gear and other parts, because of wheel rotation up help and piston rod type of counterpoint between conical cylinder liner inside the closing of the up and down reciprocating movement to complete it and open it. Plug with the tightly closed structure of piston ring have metal and nonmetal of multilayer tightly closed, when the piston ring trap by abrasion has been in the use of long time operation regulation to zero voltage regulator has lost efficacy, because this second metal by the cone piston type plays a tightly sealed utility at the same time, so the piston by the valve use fixed number of year of the survival of a common valve several times, so in the process of use without protection especially aftercare and maintain do not leak, can be successfully implemented for five leaking pipes to choose more opening and closing device, to save energy substances detract from Labour and background pollution with the application of the superficial. Plunger by the Industrial Valves structure simple science, safe and reliable, especially easy for opening and closing flexible, light, easy operation and plunger valve by opening and closing fast strengths, such as tightly closed exclusive special leakproof performance, the pistons have metal and nonmetal multi-layer tightly closed structure composed of double function, one-piece seat ( Cylinder liner) Radial taper tightly closed surface, high altitude, the contact surface or object size, good performance, on the surface of the piston ring according to the different suit to use the media to choose material aspects can increase its use range, high temperature resistance, abrasion resistance, corrosion resistance, strong resilience can, etc. , after long time use, when the piston ring if there are any abrasion protection adjustable voltage increase the original condition. Plunger cylinder structure of the valve cone in cylinder liner ( The seat) Circular cone basis is suitable for use in medium goodbye surfacing, the boron stainless steel or hard alloy, hardness of surfacing welding layer to HRC40, the boring and milling. Plunger piston ring by the end of valve repair transform technology craft is simple Marine valve, the valve does not need to spin off pipe is discharged after stopping air valve cover assembly can change a new piston ring repetitive use and other unique places. 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.
