Anti-explosion fire protection choke plug

Abstract

The invention discloses an anti-explosion fire protection choke plug which comprises a main body; the main body comprises a female head, a clamp ring and a pipe tail; the pipe tail is fixedly connected with the female head through the clamp ring; the female head is symmetrically provided with pipe teeth along the axis; the female head is internally provided with a convex surface sealing gasket; the convex surface sealing gasket adopts a NBR convex surface gasket; the pipe tail is a semitight circular column; a bolt is arranged at the bottom surface of the pipe tail; a chain which is a stainless steel chain is arranged on the bolt; and four raised edges are arranged on the outer wall of the pipe tail, and are uniformly arranged on the outer wall of the pipe tail. The anti-explosion fire protection choke plug has dust prevention and pipeline clogging functions and has the characteristics of convenience and quickness in dismounting, good sealability, high resistance to pressure, high safety performance and the like; the bolt is arranged at the bottom surface of the pipe tail, and the chain is arranged on the bolt, so that the pipe tail of the choke plug is prevented from flying away due to explosion under the condition that a potential safety hazard occurs when pressure exceeds the pressure bearing capacity, and the probability of hurting personnel is lowered.

Description

technical field [0001] The invention relates to the technical field of fire-fighting pipe connection fittings, in particular to an explosion-proof fire-fighting plug. Background technique [0002] With the further intensification of the urbanization process, high-rise buildings have been seen everywhere, and fire safety has also received more and more attention. General buildings are equipped with fire-fighting equipment, such as conventional fire extinguishers and fire hydrants. [0003] At the end of the fire-fighting pipeline, we can see joints such as fire-fighting plugs, which mainly play a role in preventing dust and blocking the fire-fighting pipeline. At present, the fire-fighting plugs on the market have defects such as complicated disassembly, poor sealing, low pressure resistance, and low safety performance. [0004] Therefore, in the prior art, there are problems such as complicated disassembly, poor sealing performance, low pressure resistance, and low safety ...
