衬套旋塞阀开关力矩的影响因素及计算研究

Affecting Factors and Calculation of Switching Torque of Bushing Plug Valve

在实际生产中衬套旋塞阀开关力矩偏大,阀门开关力矩不稳定是常有的现象。分析了影响衬套旋塞阀开关力矩的主要因素,给出了PTFE、UHMWPE等两种主要衬套材料的力学性能曲线,并提出了衬套旋塞阀开关力矩的计算方法。

The switching torque of the bushing plug valve is too large, and the switching torque is unstable in the actual production of the valve. This paper analyzes the main factors that affect the switching torque of the bushing plug valve,gives the mechanical performance curves of two main bushing materials, PTFE and UHMWPE, and proposes a calculation method for the switching torque of the bushing plug valve.
