Description
Technical field
The present invention relates to water segregator technical field, in particular to a kind of fire-fighting water segregator.
Background technique
Currently, the Chinese patent that notification number is CN104132211A disclose a kind of tool there are three the fire-fighting of water outlet with point
Hydrophone, including the major joint connecting with fire pump, there are three return connectors side by side for one end setting of the major joint, each
The driving lever installation position for installing driving lever is provided on the peripheral wall of a return connector, driving lever is used for and is set to return connector
In, control return connector switch ball valve connection.
The major joint of fire-fighting water segregator is fixedly connected with three return connectors side by side, and raw by way of casting
It produces.After completing to the casting of major joint and return connector, need to go out sprue in major joint internal turning, and main
The central axis of runner is overlapped with the central axis of major joint；It needs to go out affluent-dividing in each return connector internal turning simultaneously
Road, and the central axis of branch flow passage is overlapped with the central axis of return connector, each branch flow passage with sprue connection.By
Interlock in the extending direction of sprue and the extending direction of branch flow passage, when carrying out turnery processing, difficulty is larger, the life needed
It is longer to produce the time.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of fire-fighting water segregator, has and add
Work difficulty is smaller, and while producing spends time less advantage.
Above-mentioned technical purpose of the invention has the technical scheme that a kind of fire-fighting water segregator, packet
The return connector for including the major joint for connecting with fire pump discharge mouth, being set on the major joint, inside the major joint
Sprue is offered, offers branch flow passage inside the return connector, and the branch flow passage connection is in the sprue, described point
The control valve for controlling the branch flow passage opening and closing is provided on water swivel, the return connector is threadedly connected to the major joint
On, and the first sealing ring is sealed between the major joint and the return connector.
Through the above technical solutions, the fire-fighting is divided into the major joint and return connector of threaded connection with water segregator,
When processing, major joint and return connector can be processed respectively, and due to the small volume of major joint, so processing
When sprue inside major joint, can more convenient overturning major joint so that the processing of the major joint become it is more convenient,
Fast.Meanwhile by after the runner inside the sprue and return connector that divide the runner inside water to be divided into inside major joint,
The sprue length for needing to process inside major joint is shorter, and user more convenient can process the mainstream inside major joint
Road reduces the difficulty of processing of the fire-fighting water segregator to a certain extent, reduces flower required for fire-fighting water segregator production
The time taken.The first sealing ring pushed against between major joint and return connector becomes under the action of major joint is with return connector
Shape, and by the clearance seal between major joint and return connector, the water passed through be not easy from major joint and return connector it
Between gap in flow out, to guarantee to flow through the pressure of the fire demand water of the fire-fighting water segregator during carrying out fire-fighting fire extinguishing
It is not easy to reduce, ensure that the efficiency of fire-fighting.
Preferably, the return connector includes ontology, thread segment and extended segment, and the thread segment is threadedly connected to described
Major joint, and the end of the thread segment contacts at first sealing ring, the extended segment is prolonged to the inside of the major joint
It stretches, and the outer wall of the extended segment contacts at the inner wall of the major joint and the inner ring of first sealing ring simultaneously.
Through the above technical solutions, extended segment contacts at the inner wall of major joint far from the end of thread segment, in this way in high pressure
