Valve graphite packing method of use valve model standard description

Valve graphite packing method of use valve model standard description

Flexible graphite packing ring is made of flexible graphite sheet cut into strip or flexible graphite braided packing around in the mould, pressing to make different size of ring, this ring has excellent resilience and stability, it and the other end ring joint use, even in the harsh conditions, flexible graphite packing is also very stable and reliable. Used in high temperature, high pressure steam, heat exchange ammonia gas, hydrogen, organic solvents, hydrocarbons, cryogenic liquid and other medium ground pump, valve sealing parts. All kinds of special packing rings, such as the  45 degree Angle bevel self-tightening pad commonly used in power system, packing rings of other materials can be produced according to user requirements. Service temperature: -200¡æ – +850¡æ Service pressure: 0 — 30.0Mpa Available Specifications: ¦Õ6 — ¦Õ1000 molded ring (notched or not notched) where the notches are divided into straight notches each oblique notched valve model standard Description Valve model standard:
The valve model standard mainly refers to JB 308-1975 standard, and at the same time absorbs the provisions of the relevant standard on the model establishment. Is also issued by the National standard valve model editing method, effectively standardize the valve market model disorder, different opinions, improve the market image of the valve recognition. What parameters are mainly reflected in the valve model standard? It is mainly the simplification of the overall valve parameters, with numbers and letters.
Standard description of valve model:
The following is a comparison table on the valve model standard description method: It is mainly driven by additional, type,  structure and sealing material, pressure , size, etc. Series parameters, detailed introduces the gate valve type, valve type, the check valve type, valve type, trap model, the ball valve model, valve model such as the valve model establishment standards. So what about the many special valve models that are not in the table? Please call the Telson hotline at 021-57562898 for more information. Or go to “Valve Model Preparation Method” to check.
