The extension tube attached 7 for the petroleum that adapter ring 5 is docked with outside docks fixed situation, and the triple valve is being discharged tube head by bottom
1, after water inlet tube head 4 and the docking ring 5 being laterally discharged on tube head 13 and external petroleum pipeline abutting joint are good and stone is carried out
Oil transport, when the water inlet tube head 4 that the petroleum that needs transport only passes through the triple valve, which enters, to be discharged by bottom water outlet tube head 1, this
When only need to rotate regulation handle 12 and adjusting screw rod 11 driven to be rotated, and adjusting screw rod 11 then will drive valve body 3
Internal sealing piston 19 moves up and down, until sealing piston 19 is tucked into upper sealing half-turn baffle 15 and lower sealing half-turn baffle
In the circular hole that 20 diameters are formed, so that it is in barrier state between water inlet tube head 4 and laterally water outlet tube head 13, thus
So that petroleum is discharged from bottom water outlet tube head 1, and need petroleum from when being laterally discharged discharge from tube head 13, it is only necessary to same
It is operated such that adjusting screw rod 11 drives the sealing piston 19 inside valve body 3 to move to bottom water outlet 1 inner upper end of tube head
Seal groove 14 in blocked so that petroleum is discharged from laterally water outlet tube head 13, when needing the petroleum can be from bottom
When can be discharged at water outlet tube head 1 and laterally water outlet tube head 13, it is only necessary to sealing piston 19 be led to same mode of operation
The adjusting for overregulating screw rod 11 moves to the circular hole that sealing half-turn baffle 15 and lower sealing 20 diameter of half-turn baffle are formed
Upside, at this time bottom water outlet tube head 1 and laterally water outlet tube head 13 and water inlet tube head 4 between not by sealing piston 19
Stop, is discharged so that petroleum is discharged at tube head 1 and laterally water outlet tube head 13 by bottom simultaneously, and bottom is discharged
The circumferential inner of tube head 1, water inlet tube head 4 and lateral water outlet tube head 13 increases an encryption leak-proof device 6, can increase in this way
The leakproofness between triple valve and extension tube attached 7 after adding docking, when needing through docking ring 5 triple valve and external extension tube attached
7 when carrying out docking fixed, by taking the water inlet tube head 4 on the triple valve as an example, in docking firstly the need of on encryption leak-proof device 6
Right docking inner tube 26 be inserted into the circumferential inner into water tube head 4, concrete operations are that right docking inner tube 26 is passed through its front end band
There is arc-shaped arc tube head 27 to be firstly inserted into the inside of water tube head 4, at this time because arc tube head 27 is circular shape
Its point diameter is less than the inside diameter into water tube head 4, so that arc tube head 27 can be easily inserted into water inlet pipe
Then first 4 inside is inconjunction with by arc tube head 27 and the sealed tube of its rear end is inserted into the circumference into water tube head 4 together
Inside, at this time because the exterior circumference diameter of sealed tube is equal with water inlet 4 internal circumference diameter of tube head, and sealed tube circumference
The level-one installed on outer wall by fixing groove 28 encrypts rubber ring 29 and the circle diameter of second level encryption rubber ring 31 is larger than
The circumferential inner diameter of water inlet tube head 4, so that primary seal rubber ring and secondary seal rubber ring pass through its soft rubber material
The characteristic of matter and it is tight sealing sleeve pipe 30 and water inlet 4 circumferential inner wall of tube head between so that it is right docking inner tube 26 circumference
It is in sealing state between outer wall and the circumferential inner wall for tube head 4 of intaking, when the left docking by left end on the encryption leak-proof device 6
After the extension tube attached 7 that inner tube 25 is docked with outside installs in the same way, extension tube attached 7 and water inlet are passed through finally by nut
After docking ring 5 on tube head 4 carries out docking fixation, extension tube attached 7 docks two docking rings 5 meeting again at place with progress tube head at this time
It is squeezed and is contacted each other by the fixed effect of nut with the docking encryption piece 32 on encryption leak-proof device 6, so that external
Pipe 7 is under another sealing state with the docking ring 5 at water inlet 4 place of docking of tube head, and is added by Butt sealing piece with level-one
It is cooperated between close rubber ring 29 and second level encryption rubber ring 31 from different docking place and carries out encryption sealing, can made in this way
The fixed stronger and better tightness docked between triple valve and external extension tube attached 7 is obtained, so as to effectively prevent
Triple valve generates the case where leaking with 7 place of docking of extension tube attached, to guarantee that the petroleum inside petroleum pipeline can be transported normally
It is defeated.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
