Description
Technical field
The utility model belongs to technical field of valve manufacturing, more particularly, to a kind of L-type three-way ball valve.
Background technology
Three-way ball valve is generally divided into T-type and L-type, and existing L-type three-way ball valve can only be connected to two mutually orthogonal pipelines,
It can only play the role of distributing flow, cannot achieve the partition to flow, that is to say, that traditional L-type three-way ball valve portion has
Closed state.And then disconnected situation is that traditional L-type ball valve is just between modern industry needs to realize pipeline when in use
It cannot be satisfied use demand.
Utility model content
The utility model for overcome the deficiencies in the prior art, provides a kind of L-type three-way ball valve with closing function.
To achieve the goals above, the utility model uses following technical scheme：A kind of L-type three-way ball valve, including valve body,
Valve rod, valve handle, the spherical valve core being rotatably disposed in valve body and the medium runner in spherical valve core；The valve rod top
It is pierced by valve body with valve handle to be connected, stem lower portion is matched with spherical valve core, and rotation valve handle actuatable valve bar rotation is to drive spherical shape
Valve core rotation；The valve handle has first position, the second position and closed position；It is formed with for flow of media on the valve body
First access, alternate path and third path；
When valve handle is in first position, first access is connected by medium runner with the alternate path；
When valve handle is in the second position, first access is connected by medium runner with the third path；
When valve handle is in the closed position, ball valve is closed.
There are three states for valve handle tool in the utility model, and the closing to ball valve can be realized after realizing distribution flow, from
And realize the demand for needing to close pipeline during industrial application, it is applied widely；Secondly, it is that the pipeline of triple valve connection goes out
It, can be by closing valve blocks water outlet when existing failure, the repair hence for pipeline is more convenient, and it is difficult to reduce repair
Degree；When repairing outlet conduit, without closing total lock every time, do not interfere with the water supply of other pipelines, and maintenance personal without
It needs to run back and forth between total lock and helpdesk again, reduces repair and take, it is time saving and energy saving.
Further, the valve body is equipped with stopper, and the valve handle is equipped with and the matched limiting section of the stopper；Pass through
The cooperation of limiting section and stopper, avoidable valve handle turn is excessive, when limiting section and stopper cooperation, just realizes that spool is in company
The state of ball valve is threaded a pipe or closes, control is more accurate.
Further, the limiting section is set as two, which is downwardly extending by the valve handle side
Protrusion；When two limiting sections are matched with stopper respectively, ball valve corresponds to two different working conditions；Limiting section is by straight on valve handle
It connects and extends to form, convenient formation is high in machining efficiency.
Further, the angle between two limiting section is 180 °；Valve handle with rotate 90 ° be a position, 180 °
For the angle of valve handle rotation into 90 °, the difference between each position is apparent when being arranged and valve handle is made to have 3 positions, and converting position, and
Certifiable valve handle can quick rotation in place, position adjustment is accurate.
Further, the medium runner is arranged for L-type structure；Can be directly connected to by spool in vertical direction two
Pipeline.
Further, the valve rod top is equipped with the first rotation prevention portion coordinated with valve handle rotation stop, and lower part is equipped with and globe valve
Matched second rotation prevention portion of core；First rotation prevention portion and the second rotation prevention portion are vertical setting；Pass through the first, second rotation prevention portion
Setting, the case where ensureing the stabilization rotation stop between valve rod and valve handle and spool, be less prone to skidding, ensure to begin when valve handle rotation
Drive valve core rotation, failure rate low by valve rod eventually；And being vertically arranged due to the first, second rotation prevention portion so that the first rotation stop
Portion and valve handle, the skidding direction between the second rotation prevention portion and spool will be different, the case where to avoid the occurrence of at two while skid.
Further, the valve handle is equipped with is open with the matched rotation stop of first rotation prevention portion, first rotation stop
The top in portion connects a locking nut after being pierced by rotation stop opening；It is realized by locking nut and the anticreep of valve rod is positioned, dismounting
It is convenient.
Further, the spherical valve core is equipped with and the matched rotation stop straight slot of second rotation prevention portion；Due to setting
For straight slot so that the second rotation prevention portion can be penetrated from rotation stop straight slot side to rotation stop straight slot, to spool directly from valve body its
In be pressed on a channel in valve body, simple installation.
Further, the valve handle is equipped with the indicator for being used to indicate flow of media direction；When valve rod is in different positions
When setting, flow of media direction can be intuitively embodied by indicator.
Further, the indicator is the arrow on the valve handle；Molding is easy, high in machining efficiency.
In conclusion the utility model has the following advantages：There are three states for tool, can be realized after realizing distribution flow
Closing to ball valve, it is applied widely to realize that industrial application needs the demand of closing pipeline in the process；Secondly, repair side
Just, time saving and energy saving.
