Oil lubricating oil plug valve is one of the most matter ( See figure [ Oil lubricating oil cock] ) 。 Plug valve plug body for cone ( There are also the cylinder) , and the Industrial Valves cone hole surface appropriate composition tightly closed. Small-scale packless plug valve is also called as ''. Specially manufacturing lubricating grease from the top of the plug body perfusion body between the taper hole and the plug body, forming oil film to minimize open-close torque increase tightly closed and use fixed number of year of survival. Q: what strengths does t cock valve principle is what? A: with hole plug body as the opening and closing of the valve. Three-way cock way according to the structure can be divided into tight pattern plug valve, sealing plug valves, filler plug valve and oil plug valve. 2, small fluid resistance. According to the passage way points, can be divided into straight-through, three general formula, and the four general formula 3 kinds. 。 Plug valve is to use one of the first valve, simple structure, switch speed, small fluid resistance. Common straight-through type is mainly used for cutting fluid. In order to expand the application range of the cock, have produced many new structures. Ordinary cock on finishing the direct contact between metal plug body and the body tightly closed, so less tightly closed, opening and closing force is big, easy to wear, generally can only be used for low ( No more than 1 million mpa) And small diameter ( Less than 100 mm) The occasion. The three-way cock valve is mainly used for medium of open and closed pipelines and facilities. Its office pressure of up to 64 million mpa, supreme office temperature can reach 325 ℃, the maximum diameter is 600 mm. Plug with the valve rod rotation body, as a successful opening and closing action. 3, simple structure, relatively large and small, light weight, easy to maintenance. T cock valve main advantages as follows: 1, suit to use Yu Changchang operation, opening and closing speed, light. 4, 5, tightly sealed performance is good is not affected by the installation direction of limit, the flow of medium can be arbitrary. There are several ways to plug valves channel. Three and four general formula plug valve is suitable for use in fluid directional control plug Industrial Valves opening and closing is a perforated cylindrical Marine valve body, vertical to the axis of the channel rotate, thus achieve the objectives of the opening and closing the channel. 6, no oscillation, little noise. 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.
