Connecting joint for connecting fire-fighting pipeline and water meter

Technical Field

The utility model belongs to the technical field of the fire-fighting pipeline, a attach fitting that is used for fire-fighting pipeline and water gauge to connect is related to.

Background

The fire-fighting pipeline refers to a pipeline material which is used for fire fighting, connecting fire-fighting equipment and equipment, and conveying water, gas or other media for fire fighting. Conventional fire fighting pipelines are connected by welding, threads, flanges, hoops and the like. In order to ensure that the fire fighting pipeline can be effectively used all the time, the fire fighting pipeline needs to be subjected to daily maintenance management, which is mainly embodied in the aspects of testing and monitoring the water flow and pressure of the fire fighting pump.

In the prior art, in order to monitor the water outlet flow of the fire fighting pump, a flowmeter is additionally arranged between two adjacent fire fighting pipelines by technical personnel in the field, but two ports of the flowmeter usually adopt flange structures or thread structures, and when the flowmeter is installed, bolts or thread sleeves need to be installed, so that the installation is inconvenient.

Disclosure of Invention

The utility model aims at having above-mentioned problem to current technique, provided a attach fitting that is used for fire-fighting pipeline and water gauge to connect, the utility model aims to solve the technical problem that: how to improve the convenient degree of being connected between fire control pipeline and the water gauge.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a attach fitting that is used for fire service pipeline and water gauge to connect which characterized in that, is including the connecting pipe that is used for fixed water gauge, the tip of connecting pipe has the connecting portion that is the tube-shape, the external diameter of connecting portion is less than the external diameter of connecting pipe, concave locating hole has on the periphery wall of connecting portion.

The structural design of this connector can utilize clamp and fire-fighting pipeline complex structure among the prior art ingeniously, with the mode that connector application advances between the fire-fighting pipeline and can adopt clamp connection, make can high-speed joint between connector and the fire-fighting pipeline, particularly, conventional clamp inner circle all has the flange that is used for axial positioning fire-fighting pipeline, after the tip of connecting pipe and fire-fighting pipeline butt joint intercommunication, the clamp cover is established in the junction of connecting portion and fire-fighting pipeline, the flange on the clamp can make clamp and connecting pipe axial spacing in the bayonet socket, the intercommunication between connecting pipe and the fire-fighting pipeline is realized to the locking of rethread clamp self, thereby realize the quick installation of connecting pipe and fire-fighting pipeline, the effect of hugging that is close to the position of clamp on connecting pipe and the fire-fighting pipeline more simultaneously is better, the external diameter of connecting portion is less than the external diameter of connecting pipe makes the bayonet socket more be close to the axis of connecting pipe make the clamp be close to the connecting pipe axis, increase the effect of hugging close to the position of connecting pipe terminal surface and fire-fighting pipeline position on the connecting pipe terminal surface, also can guarantee the sealed effect of connecting pipe and fire-fighting pipeline connection.

In foretell be arranged in fire control pipeline and water gauge connection's attach fitting, the location mouth is the ring-type, the periphery wall of connecting portion leans on the face including being located between location mouth and the connecting portion terminal surface, it is the face of cylinder to lean on the face. The flange card on the clamp is gone into behind the location mouth and is leaned on the face to be located the clamp, is cylindric and leans on the face can lean on with the inner wall laminating of clamp to lean on, can not only increase the area of contact of connecting pipe and clamp, improves the effect that the clamp is connected, can also improve clamp locking connecting pipe back, radial aversion between connecting pipe and the clamp to guarantee connecting pipe and fire control pipe connection's sealed effect.

In the above-mentioned connector for connecting a fire-fighting pipeline and a water meter, the connecting portion is coaxial with the connecting pipe, and the connecting pipe has a flat annular surface connected with the outer wall of the connecting portion. The annular face can lean on with the one end terminal surface of the orientation connecting pipe of clamp to lean on, can share the axial effort that the clamp flange received when clamp locking connecting pipe and fire control pipeline, avoids the flange atress of clamp to concentrate and appear breaking.

In the above-mentioned attach fitting for fire-fighting pipeline and water gauge are connected, the periphery wall of connecting portion still includes the inner face that flushes with the face of leaning on, the inner face is located between annular face and the locating port. Inner surface and support and lean on the both sides of face distribution in the location mouth all can be used to leaning on of clamp inner circle lateral wall, make the flange of clamp can be at the stable atress in the location mouth, can increase area of contact moreover, the radial leap up who appears between common restriction attach fitting and the fire-fighting pipeline moves, and the inner surface can also regard as the strengthening rib between location mouth and clitellum simultaneously, increases structural strength.

In the above-described joint for connecting a fire fighting pipe and a water meter, the length of the inner face in the axial direction of the connecting pipe is smaller than the length of the abutting face in the axial direction of the connecting pipe. The inner face length difference can set up according to the port internal diameter of different fire control pipelines, and fire control pipeline port internal diameter is different and chooses for use different clamps, sets up the axial length of inner face according to the clamp of difference to the outer wall that makes the clamp can support with the annular face all the time and lean on, shares the axial external force that the flange received.

In the above-described joint for connecting a fire fighting pipe and a water meter, the length of the inner face in the axial direction of the connecting pipe is less than half of the length of the abutting face in the axial direction of the connecting pipe. The structural arrangement of the whole connecting joint is more compact through the design.

Compared with the prior art, this a attach fitting for fire control pipeline and water gauge are connected has following advantage:

1. this connector and fire-fighting pipeline can utilize the mode of clamp to connect after the butt joint, and convenient operation is swift.

2. The external diameter that the external diameter of connecting pipe is greater than connecting portion makes the external diameter of connecting portion be less than the external diameter of connecting pipe, and the location mouth that will be used for clamp flange card to go into sets up on connecting portion, enables the clamp and is close to the inside passage of connecting pipe, improves the clamp and is close to the laminating effect of connecting intraductal passageway position to the connecting pipe terminal surface to guarantee the sealed effect of clamp connection.
