Keeping the temperature asbestos is ring structure and, the valve body tube passage of the heat preservation asbestos and valve body consistent with the valve body tube channel diameter of valve body
Laid inside has fluoroplastics lining.
Preferably, connecting flange is mounted on the valve body tube wall at the valve body both ends.
Preferably, the rod structure upper end of the cock stem is equipped with handle, the square hole opened up on handle and cock stem
The square block clearance fit of rod structure upper end.
The technical effect and advantage of the utility model: the thermal-insulation plug valve is set in the rod structure of the intracorporal cock stem of valve
There is spring, spring works as a buffer, and so that cock stem is not generated stagnant lock plus with the rolling bearing that valve deck cooperates, and switchs ineffective
The phenomenon that, the heat preservation asbestos of insulation effect, valve body tube passage and heat preservation asbestos upper berth have been installed on the valve body tube passage of valve body
Fluoroplastics lining equipped with leakproof, the two groups of connecting flanges installed on the valve body tube wall of valve body are for the connection with pipeline, cock
The handle of the rod structure upper end installation of bar can removed when not in use, and the thermal-insulation plug valve is structurally reasonable, easy to operate, push away
It recommends and is widely used.
