Air operated tamper tee and tee removal wrench

Abstract

The invention relates to the field of dismounting-prevention tee joints, and discloses a dismounting-prevention tee joint capable of being operated with gas and a tee joint dismounting wrench. A sealing plunger assembly (1) is arranged in a tee joint body (4) and comprises a plunger shell (101), beads (102), springs (103) and a plunger core (104). The beads (102) extend into bead embedding grooves (401) in the inner wall of the tee joint body (4). The plunger core (104) is provided with a plunger core internal cavity (1043). Inward-convex walls (1044) are further arranged at an opening of the plunger core internal cavity (1043). By adopting the technical scheme, a plug, a blank cap and the sealing plunger assembly can be taken out of the tee joint only through the special tee joint dismounting wrench, dismounting can be conducted with gas, and the sealing plunger assembly cannot be jacked into the tee joint through the wrench, so that the dismounting-prevention characteristic is better improved, and the tee joint can be effectively prevented from being dismounted by non-work personnel.

Description

technical field [0001] The invention relates to the field of anti-disassembly tees, in particular to an anti-disassembly tee which can be operated with air and a special disassembly wrench thereof. Background technique [0002] As disclosed in patent 201510466257.0, the anti-dismantle tee that can be operated with gas can remove the plug and then install the ball valve without cutting off the gas source. In this way, the user can continue to use gas during operation. It is very convenient, but the anti-demolition performance of this anti-demolition tee is not strong. After removing the plug and stuffy cover with a general hexagonal nut, the seal located inside the tee can be easily taken out, and non-professionals open the anti-demolition tee Afterwards, stealing gas and privately connecting pipelines not only caused property losses, but also caused great safety hazards. Even if professionals disassemble, the plunger assembly in the tee may be pushed into the tee, and then ...
