Underground line excavated.Sewage conduct, natural gas line and water supply pipe etc. can be encountered during excavation of subway, when
When excavation of subway encounters above-mentioned pipeline, it is necessary to be transformed to above-mentioned several pipelines and give way to subway, above-mentioned is several
The shutoff valve closed on pipeline or pipeline is needed to construct when pipeline is transformed, sewage conduct closes the life to resident
Influence is smaller, and the normal life of resident, especially tap water will be greatly influenced after natural gas line and water supply pipe closing
The daily life on resident of cutting off the water caused by after closedown of pipeline influences very big.
Utility model content
The utility model provides a kind of shunting shutoff valve for water supply pipe, can carry out shunting operation, when certainly
When carrying out waterpipe and encountering other municipal constructions and need to close, the first shunt conduit or the second shunt conduit are avoided by Temporary connections
The water supply pipe job location of disconnection is connected to the shunt conduit of the shunting shutoff valve of the other end, although water supply pipe
Because construction has carried out the closing of part, the Temporary connections for connecting two shutdown sides shunting shutoff valves are avoided into job location, are led to
It crosses Temporary connections and continues tap water supply operation.
In order to solve the above technical problems, technical solution used by the utility model is as follows:
A kind of shunting shutoff valve for water supply pipe, including valve body, there are two connector, valves for valve body
One connector of ontology is equipped with the first shunt conduit, and the first shunt conduit is equipped with the first relief valve and first switch valve,
For first relief valve between first switch valve and valve body, the first relief valve is equipped with first pressure gauge, the first isocon
The outlet in road is equipped with the first limit expansion joint；Another connector of valve body be equipped with the second shunt conduit, second point
Flow tube road is equipped with the second relief valve and second switch valve, and the second relief valve is between second switch valve and valve body, and the
Two relief valves are equipped with second pressure gauge, and the outlet of the second shunt conduit is equipped with the second limit expansion joint.
First limit expansion joint and the second limit expansion joint are single flange limit expansion joint.
First relief valve and the second relief valve are Spring-Loaded Pressure Relief Valve.
By adopting the above technical scheme, the utility model has the following beneficial effects:
Compared with the shut-off valve that can only be closed and be opened on existing water supply pipe, in the utility model one
Shunting shutoff valve of the kind for water supply pipe can carry out shunting operation, need when water supply pipe encounters other municipal constructions
When closing, the first shunt conduit or the second shunt conduit avoid the water supply pipe job location disconnected by Temporary connections,
It is connected to the shunt conduit of the shunting shutoff valve of the other end, it, will although water supply pipe has carried out the closing of part because of construction
The Temporary connections for connecting two shutdown sides shunting shutoff valves avoid job location, continue tap water by Temporary connections and supply
Water operation avoids the case where causing construction area to cut off the water because of construction, ensure that the normal tap water of construction Area Inhabitants supplies
It answers, to ensure that the daily life of construction Area Inhabitants is not influenced by cutting off the water；First shunt conduit, the second shunt conduit are equal
Equipped with relief valve, avoids the tap water pressure in tap water main pipeline excessive, Temporary connections are damaged, influence Temporary connections
Normal water supply；The outlet of first shunt conduit and the outlet of the second shunt conduit are equipped with limit expansion joint, guarantee first point
The connector of the connector and the outlet of the second shunt conduit that flow pipe outlet has certain displacement, connects convenient for Temporary connections.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic diagram of the working condition of the utility model.
Valve body 1, the first shunt conduit 2, the first relief valve 3, first switch valve 4, first pressure gauge 5, the first limit
Expansion joint 6, the second shunt conduit 7, the second relief valve 8, second switch valve 9, second pressure gauge 10, the second limit expansion joint
11。
Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing:
As shown in Figure 1, a kind of shunting shutoff valve for water supply pipe, including valve body 1, valve body 1 have
