Connecting pipe assembly

Technical Field

The utility model belongs to the technical field of the takeover, a takeover subassembly is related to.

Background

In a radiator system, the connection of the radiators to the control valves of the system and the supply of hot water are generally effected via connecting lines. And need maintain or inside the sewage that can remain after using for a long time at radiator system, all be provided with the blowoff valve on traditional radiator, consequently can only demolish the radiator when needing discharge sewage, but work load is very big and waste time like this. In order to achieve quick discharge of sewage, a conventional method is to install an additional plug or a sewage valve on a heater, and discharge the sewage by detaching the plug or opening the valve. However, the installation of the plug or the connection of the drain valve requires some modification of the structure of the conventional radiator, which complicates the structure of the radiator system.

Disclosure of Invention

The utility model aims at the above-mentioned problem that prior art exists, provide a connecting pipe subassembly, the technical problem that solve is the structure of how to simplify the radiator system when improving the blowdown convenience.

The purpose of the utility model can be realized by the following technical proposal:

the utility model provides a connecting pipe subassembly, include along the axial run through be provided with the takeover one of passageway one, a serial communication port, this connecting pipe subassembly still includes link firmly in the takeover one outside and with takeover one part coincidence take over two, it is provided with passageway two to run through along the axial on the takeover two, passageway one is mutually perpendicular with the orientation of seting up of passageway two, passageway one middle section and the partial coincidence of passageway two middle section, be equipped with annular boss in the one port of passageway two, two threaded connection of passageway have a sealing rod, sealing rod one end seals the centre bore of annular boss, the sealing rod other end is located the other port department of passageway two and is equipped with sealing washer one in this end outside of sealing rod.

When the connecting pipe assembly is used, two ends of the first connecting pipe are respectively connected with the heating radiator and the valve so as to enable the connecting pipe assembly to play a normal connecting role, the second connecting pipe is used as a sewage discharge pipe, and the central hole of the annular boss is sealed by the first sealing ring and one end of the sealing rod under a normal state so as to prevent hot water in the first connecting pipe from flowing out of the second connecting pipe. When sewage is required to be drained, the tool is sleeved on the sealing rod and rotates, so that the sealing rod moves towards the direction far away from the annular boss to open the central hole of the annular boss, and sewage in the heating system can flow into the channel II from the channel I and directly discharged outwards through the central hole of the annular boss and one port of the channel II.

This connecting pipe subassembly can enough play normal connection effect through the setting of taking over one, has increased the blowdown function again through the setting of taking over two and sealing rod simultaneously, when radiator system breaks down or the radiator will discharge the inside liquid of pipeline for the user can only through operating sealing rod alright direct discharge sewage under the condition of not dismantling other parts of radiator system, has improved user's blowdown convenience well. And the second connecting pipe is directly integrated with the first connecting pipe, so that the radiator is not required to be connected with the radiator, holes are formed in the radiator and the like, and the structure of the radiator system is simplified.

In the pipe connecting component, the middle section of the second channel is a threaded section, the second channel further comprises a yielding section and a water outlet section which are positioned on two sides of the threaded section, the annular boss is positioned between the water outlet section and the threaded section, the sealing rod is connected in the threaded section in a threaded manner, one end of the sealing rod provided with the first sealing ring is positioned in the yielding section, and the end face of the sealing rod is provided with the straight groove.

A straight groove is formed in one end face, provided with the sealing ring, of the sealing rod, so that a user can operate the sealing rod by only using a straight screwdriver, and the pollution discharge convenience of the user is further improved.

In foretell connect the pipe assembly, the sealing rod includes pole portion and links firmly sealed head and the closing plate at pole portion both ends respectively, and sealed head stretches into the centre bore of annular boss and the sealed head outside is equipped with sealing washer two, and the closing plate is located lets the position section in and sealing washer one locate the closing plate outside, links firmly the operating head that the external diameter is less than the section internal diameter of stepping down on the closing plate, and the overhead operation is located to a word groove.

In the pipe connecting component, the outer side of one end, close to the annular boss, of the rod part is provided with a conical sealing surface, and the conical sealing surface abuts against a port of a central hole of the annular boss.

A sealing ring II is arranged on the outer side of the sealing head II to form one sealing, and meanwhile, a conical sealing surface abuts against a port of a central hole of the annular boss to form two seals, so that the double-sealing structure enables the sealing effect of the pipe connecting assembly to be better.

In the above-mentioned junction block assembly, the port of the relief section is inwardly constricted.

After the sealing rod is assembled in the second connecting pipe, the two ends of the connecting pipe at the yielding section are contracted, so that the port of the yielding section is contracted inwards, the movement of the sealing rod can be limited, and the sealing rod is prevented from falling out due to excessive rotation.

In the pipe connecting component, the outer sides of the two end parts of the connecting pipe where the water outlet section is located are provided with a plurality of convex rings along the axial direction.

When in pollution discharge, the two ends of the connecting pipe where the water outlet section is located are connected with a pollution discharge hose, and each convex ring can play a fastening role to prevent the pollution discharge hose from being separated.

Compared with the prior art, this connect the pipe assembly and can enough play normal connection effect through the setting of taking over one, has increased the blowdown function again through the setting of taking over two and sealing rod simultaneously, when radiator system breaks down or the radiator will discharge the inside liquid of pipeline for the user can only through operating sealing rod alright direct discharge sewage under the condition of not dismantling other parts of radiator system, has improved user's blowdown convenience well.

In addition, the second connecting pipe is directly integrated with the first connecting pipe, so that the connecting with the heating radiator, the punching on the heating radiator and the like are not needed, and the structure of the heating radiator system is simplified.
