Description

Fire-fighting pipeline air tightness detection device

Technical Field

The utility model belongs to the technical field of fire-fighting equipment, concretely relates to fire pipeline air tightness check out test set.

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. The fire pipeline needs to carry out the gas tightness regularly and detects, because the aperture size of fire pipeline can't change, when detecting the fire pipeline in different apertures, needs different gas tightness detection device.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model aims to solve the technical problem that a fire pipeline air tightness detection device is provided, the air tightness detection can be carried out to the fire pipeline in different apertures.

In order to solve the technical problem, the utility model discloses a technical scheme be:

the utility model provides a fire pipeline air tightness check out test set, includes the box, be equipped with the port that is used for fire pipeline air tightness to detect on the box, the port comprises a plurality of first rings that arrange in proper order to the inside direction of box along the box surface, and a plurality of first ring open-ended internal diameter is followed the box surface reduces gradually to the inside direction of box, and is a plurality of the centre of a circle of first ring is located same straight line, is located the first ring of port innermost is in with the setting air pump in the box is connected, every all be equipped with the connecting portion with fire pipeline sealing connection on the inside wall of first ring.

Further, the connecting portion is a thread extending from one end of the first ring to the other end of the first ring.

Further, connecting portion still include the second ring, the second ring is located in the first ring, just the inner wall of second ring with the inner wall sealing laminating of first ring, second ring open-ended internal diameter is less than or equal to fire control pipeline open-ended internal diameter, second ring open-ended terminal surface is equipped with first sealing washer, the terminal surface at first sealing washer place is the terminal surface of second ring and fire control pipeline contact.

Furthermore, the connecting portion further comprises a second sealing ring, a gap is formed between two adjacent first circular rings, and the second sealing ring is arranged in the gap.

Further, the number of the first circular rings is three.

The beneficial effects of the utility model reside in that:

by adopting the technical scheme provided by the utility model, when the air tightness of the fire fighting pipeline with larger aperture is detected, the fire fighting pipeline is hermetically connected with the first ring with larger opening; if carry out the gas tightness to the less fire pipeline of aperture and examine time measuring, then fire pipeline and the less first ring sealing connection of opening, the utility model discloses a different first ring setting of a plurality of opening internal diameters can carry out the gas tightness to the fire pipeline in different apertures and detect.

Detailed Description

In order to explain the technical content, the objects and the effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.

Referring to fig. 1 and 3, a fire pipeline air tightness detection device, includes box 1, is equipped with the port 3 that is used for fire pipeline 2 air tightness to detect on box 1, and port 3 comprises a plurality of first rings 4 that arrange in proper order to box 1 inside direction along box 1 outside surface, and a plurality of first ring 4 open-ended internal diameters reduce gradually to box 1 inside direction from box 1 outside surface, and is a plurality of the centre of a circle of first ring 4 is located same straight line, is located port 3 the most inside first ring 4 is connected with the air pump that sets up in box 1, all is equipped with connecting portion 5 with fire pipeline 2 sealing connection on every first ring 4's the inside wall.

The use principle is as follows:

if the air tightness of the fire fighting pipeline 2 with the larger diameter is detected, the fire fighting pipeline 2 is in sealing connection with the first ring 4 with the larger opening; if carry out the gas tightness when examining the less fire pipeline 2 in aperture, then fire pipeline 2 and the less 4 sealing connection of first ring in opening, because the utility model discloses set up the different first ring 4 of a plurality of opening internal diameters in port 3 department, so can carry out the gas tightness to the fire pipeline 2 in different apertures and detect.

Referring to fig. 2 and 3, the connection portion 5 of the present embodiment is a thread extending from one end of the first ring 4 to the other end, and the connection of the first ring 4 to the fire fighting pipeline 2 is facilitated by using the present embodiment. Referring to fig. 2 and 3, the connecting portion 5 of this embodiment further includes a second ring 6, the second ring 6 is disposed in the first ring 4, and the inner wall of the second ring 6 is in sealing fit with the inner wall of the first ring 4, the inner diameter of the opening of the second ring 6 is smaller than or equal to the inner diameter of the opening of the fire fighting pipeline 2, the end face of the opening of the second ring 6 is provided with a first sealing ring 7, the end face where the first sealing ring 7 is located is the end face where the second ring 6 contacts the fire fighting pipeline 2, by adopting the technical scheme, when the air tightness detection is performed on the fire fighting pipeline 2, one end of the fire fighting pipeline 2 can be abutted against the first sealing ring 7 of the second ring 6, and the tightness of the fire fighting pipeline 2 detection is improved. Referring to fig. 2 and 3, connecting portion 5 of this embodiment still includes second sealing washer 8, is equipped with the clearance between two adjacent first rings 4, and second sealing washer 8 is located in the clearance, adopt this technical scheme, work as the utility model discloses carry out the leakproofness to the fire pipeline 2 in less aperture and examine time measuring, second sealing washer 8 can with the outer wall laminating of fire pipeline 2, improve the leakproofness to the fire pipeline 2 in less aperture detects.

Referring to fig. 3, the number of the first circular rings 4 in the present embodiment is three, and the airtight detection can be performed on the fire fighting pipelines 2 with three different apertures, and the number of the first circular rings 4 is not limited to three.

The above mentioned is only the embodiment of the present invention, and not the limitation of the patent scope of the present invention, all the equivalent transformations made by the contents of the specification and the drawings, or the direct or indirect application in the related technical field, are included in the patent protection scope of the present invention.
