Description
Technical field
The present invention relates to tee ball valve technical field, more particularly to a kind of well-set tee ball valve.
Background technology
Tee ball valve has T-shaped and L-type, T-shaped to make three mutual UNICOMs of orthogonal pipeline and cut-out Article 3 passage, rises and divides
Stream, interflow effect；L triple ball-types can only connect two mutually orthogonal pipelines, it is impossible to while keep the phase of Article 3 pipeline
It is intercommunicated, only play distributional effects.The operation principle of tee ball valve is loved by rotary valve to make valve unimpeded or inaccessible.Ball valve switch
It is light, small volume, very heavy caliber can be made, sealed reliable is simple in construction, easy to maintenance, and sealing surface is often closing with sphere
State, it is not easy, by medium erosion, to be widely used in every profession and trade.
The interface for the tee ball valve commonly used in industry is typically attached using flange, it is known that in tee ball valve
Flange often it is difficult to ensure that concentric with pipeline, and it is difficult to ensure that the up rightness of pipeline and end face of flange, simultaneously because three
Pass ball valve has three interfaces, and therefore, often producing larger installation between pipeline and tee ball valve in the installation of reality should
Power, so as to occur connecting do not fasten with face leakage seal it is poor phenomena such as.
The content of the invention
The invention aims to solve shortcoming present in prior art, and a kind of well-set threeway proposed
Ball valve.
To achieve these goals, present invention employs following technical scheme：
A kind of well-set tee ball valve, including ball valve body, the ball valve body include the first outlet pipe, the second outlet pipe
And water inlet pipe, first outlet pipe and the second outlet pipe are concentric, and the first outlet pipe is vertical with water inlet pipe, and the first outlet pipe is remote
One end from the second outlet pipe is fixed with boss, and boss structure annular in shape, and side of the boss away from the first outlet pipe is opened
Mounting groove provided with circle, the inside of the mounting groove are provided with the sealing ring of annular, are provided with the pipeline section of the first outlet pipe
Connector, and connector structure in the form of annular discs, the end face center of the connector offers through hole, and through hole is socketed in first and gone out
On water pipe, the end surface side edge of connector offers bolt hole, and bolt hole is provided with four groups, and bolt hole is in connector described in four groups
Circumferentially array on end face, the side of the first outlet pipe offers screwed hole, pressure release screw is provided with the screwed hole, described
The head of pressure release screw offers the groove of circle, and the side of pressure release screw offers relief hole, and relief hole connects with groove.
Preferably, control handle is installed on the ball valve body.
Preferably, first outlet pipe, the second outlet pipe are identical with the mounting structure of water inlet pipe.
Preferably, the overall diameter of the boss is more than the diameter of through hole on connector.
Preferably, 1.2-1.5 times of the overall diameter of a diameter of first outlet pipe of through hole on the connector.
Preferably, second outlet pipe is welded to connect with boss, and the second outlet pipe and boss are concentric.
Compared with prior art, the beneficial effects of the invention are as follows：
By setting sealing ring, boss and connector in the present invention, it ensure that connection is very firm, eliminate on pipeline end face
Flange mount stress caused by bias, improve the sealing of end face；By setting pressure release screw, vacuum can internally occur
And when causing the control handle to be difficult to rotate, carry out pressure release is carried out, in order to which handle rotates, improves the convenience of operation.
Brief description of the drawings
Fig. 1 is a kind of structural representation of well-set tee ball valve proposed by the present invention；
Fig. 2 is a kind of structural representation of the pressure release screw of well-set tee ball valve proposed by the present invention.
In figure：1 water inlet pipe, 2 pressure release screws, 3 sealing rings, 4 boss, 5 connectors, 6 first outlet pipes, 7 control handles, 8
Second outlet pipe.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.
Reference picture 1-2, a kind of well-set tee ball valve, including ball valve body, ball valve body include the first outlet pipe
6th, the second outlet pipe 8 and water inlet pipe 1, the first outlet pipe 6 and the second outlet pipe 8 are concentric, and the first outlet pipe 6 hangs down with water inlet pipe 1
Directly, the one end of the first outlet pipe 6 away from the second outlet pipe 8 is fixed with boss 4, and 4 structure annular in shape of boss, and boss 4 is away from
The side of one outlet pipe 6 offers the mounting groove of circle, and the inside of mounting groove is provided with the sealing ring 3 of annular, the first outlet pipe 6
Pipeline section on connector 5, and 5 structure in the form of annular discs of connector be installed, the end face center of connector 5 offers through hole, and logical
Borehole jack is connected on the first outlet pipe 6, and the end surface side edge of connector 5 offers bolt hole, and bolt hole is provided with four groups, four groups of bolts
Circumferentially array, the side of the first outlet pipe 6 offer screwed hole, are provided with and let out in screwed hole on the end face of connector 5 in hole
Screw 2 is pressed, the head of pressure release screw 2 offers the groove of circle, and the side of pressure release screw 2 offers relief hole, and relief hole
Connected with groove, control handle 7, the installation knot of the first outlet pipe 6, the second outlet pipe 8 and water inlet pipe 1 are installed on ball valve body
Structure is identical, and the overall diameter of boss 4 is more than the diameter of through hole on connector 5, a diameter of first water outlet of through hole on connector 5
1.2-1.5 times of the overall diameter of pipe 6, the second outlet pipe 8 are welded to connect with boss 4, and the second outlet pipe 8 and boss 4 are concentric.
Operation principle：During operation, sealing ring 3 is loaded in the mounting groove on boss 4, the pipe end for then accessing needs
Flange on face is attached with connector 5 by bolt, due to the outer wall of the through hole on connector 5 and the first outlet pipe 6 it
Between there is certain gap, so, when the flange on pipeline end face and pipeline be not concentric, can appropriate offset coupling member 5, really
Protect connector 5 to be fastenedly connected with the flange on pipeline end face, connection is very firm, eliminates the flange on pipeline end face because of bias
Caused by mount stress, meanwhile, improve the sealing of end face；Vacuum, which internally occurs, in pressure release screw 2 causes control handle difficult
Carry out pressure release can be turned on during rotating, improves the convenience of operation.
