Abstract
The utility model discloses a pneumatic adjusting valve, which comprises a valve core. A base is arranged at the bottom of the valve core, a polytetrafluoroethylene ring is arranged on the contact portion of the base and the valve core, and a metal outer ring is arranged outside the polytetrafluoroethylene ring. Further, the metal outer ring is a steel ring. The pneumatic adjusting valve has the advantages of achieving anti-abrasion effect and being not easy to expand outwards and convenient to install.
Description
Technical field
The utility model relates to a kind of field of valve, particularly a kind of pneumatic control valve.
Background technique
Existing pneumatic control valve base all is a tetrafluoroethylene on the present market, and teflon is a high-abrasive material, but all is that teflon is easily to expanding installation inconvenience so all around.
