Problems solved by technology

However, when in use, due to the unbalanced water velocity in the fire-fighting pipeline, it will have an impact on the fire-fighting pipeline, causing the fire-fighting pipeline to vibrate, and the impact stress generated by the fire-fighting pipeline is particularly concentrated at the joint of the clamp
With the prolongation of use time, the pipe connection is easy to loosen, resulting in water leakage; therefore, it is usually necessary to regularly check whether the pipe connection is leaking, and perform corresponding maintenance, and the maintenance cost is relatively high

Embodiment 1

[0039] Such as figure 1 , 2 As shown, a fire-fighting pipe fitting includes a pipe body 1, a connecting pipe 2 and a fixed pipe 3, the pipe body 1 is a steel pipe, the two ends of the connecting pipe 2 are respectively sleeved on the two pipe bodies 1, and the inner wall of the connecting pipe 2 is fixed A retaining ring 21 is provided. The fixed pipe 3 includes two semi-annular half pipes 31 and a connecting assembly 4 for fixing the two half pipes 31. The fixed pipe 3 is sleeved outside the connecting pipe 2. The connecting assembly 4 includes connecting bolts 41 and nuts 42. The half pipes 31 Ear plates 7 are fixedly arranged on both sides of the ear plate 7, and a perforation 71 is provided on the ear plate 7, and the connecting bolt 41 passes through the perforation 71 of the two ear plates 7 and is threadedly connected with the nut 42.

[0040] Such as figure 2 , 3 As shown, the side wall of the fixed ring 21 close to the pipe body 1 is provided with an elastic seal...

Embodiment 2

[0050] A method for installing fire-fighting pipe fittings, comprising the following steps:

[0051] S1. Cut several sections of steel pipes with the same diameter according to the design length at the construction site;

[0052] S2. Process a concave groove 11 around the circumference on the outer wall at both ends of each section of the steel pipe close to the end face;

[0053] S3. Spray anti-rust paint on the outer surface of each section of the steel pipe after the groove 11 has been processed, and then spray the topcoat to form a multi-section fire pipe body 1 that meets the design length;

[0054] S4. Connect the two adjacent pipe bodies 1 through the connecting pipe 2, so that the end face of the pipe body 1 is pressed against the elastic sealing ring 211, and then the two half pipes 31 are fixed on the connecting pipe 2 through the connecting assembly 4, and the flange 32 Insert it into groove 11.

Abstract

The invention relates to a fire-fighting pipe fitting and its installation method, which belongs to the technical field of fire-fighting, and includes a pipe body, a connecting pipe and a fixing pipe. A fixing ring is provided, and the side wall of the fixing ring near the pipe body is provided with an elastic sealing ring that interferes with the end surface of the pipe body; the fixing pipe includes two semi-circular half pipes and a connecting assembly for fixing the two half pipes , the fixing tube is sheathed outside the connecting tube, and the fixing tube is provided with an elastic member for hindering the axial sliding of the connecting tube. When the pipe body is subjected to axial impact, the pipe body will act on the elastic sealing ring with the impact force, the elastic sealing ring absorbs part of the impact force, and then the remaining impact force drives the connecting pipe to slide axially, so that the elastic part is compressed and acts as a buffer The function of energy absorption prevents water leakage at the joint of the pipe body and reduces maintenance costs.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a fire pipe fitting and an installation method thereof. Background technique [0002] According to fire-fighting requirements, fire-fighting equipment such as indoor fire hydrants for fire-fighting must be installed in buildings. The indoor fire hydrant is the interface with a valve for the indoor pipe network to supply water to the fire site. It is used as an indoor fixed fire-fighting facility for buildings and the like. It is usually installed in a fire hydrant box and is matched with equipment such as fire hoses, water guns, and fire hose reels. use. The water supply pipes in the building are divided into independent domestic water pipes and fire-fighting pipes. Among them, the fire-fighting pipes include pipes connected to indoor fire hydrants and pipes connected to indoor sprinklers. It is connected with indoor fire pipes to provide water for indoor fire hydrants ...
