Specific embodiment
The structure to the continuous circulating valve of coordinated type of the invention is described in detail below in conjunction with the accompanying drawings.
The continuous circulating valve of coordinated type provided by the present invention as depicted in figs. 1 and 2, including：Primary path and bypass.Valve body
Box 8 on 1 is used to be connected with the pin thread of top drilling tool, and the pin thread 15 of the bottom of valve body 1 is used to be connected with the box of lower drilling tool.
After removing bypass plug 14, the by-pass prot on valve body 1 is connected with bypass pipeline, and the keying of primary path is realized by ball valve, is led to
Cross the keying that bypass sliding sleeve 13 realizes bypass.
Specifically, the continuous circulating valve of the coordinated type includes valve body, the ball valve in the valve body, knob 10, bypass
Plug 14 and the driving gear 11 being from top to bottom sequentially arranged in the valve body 1, driven gear sliding sleeve 12 and bypass sliding sleeve
13。
The knob 10 is fixedly connected with driving gear 11, and the outer end of knob 10 is arranged in the hole formed on valve body 1, knob
10 the inners are fixedly connected with the valve element 3 of ball valve, for rotary spool 3.The driving gear 11 is bevel gear.Driven gear sliding sleeve
12 bottoms for being arranged on valve element 3, the upper surface of driven gear sliding sleeve 12 is the bevel gear being engaged with driving gear 11, driven tooth
The lower end for taking turns sliding sleeve 12 is locally extended downwardly and inserted in the groove formed on the upper end outer peripheral face of bypass sliding sleeve 13.Exactly,
The lower end of driven gear sliding sleeve 12 locally extends downwardly, and the outside of the elongated end is by the boss support formed on valve body 1 and the side
Can be turned an angle on the boss, the groove formed on the inner side insertion upper end outer peripheral face of bypass sliding sleeve 13 of the elongated end
It is interior, so, when turning knob 10 drives driving gear 11 to rotate, can easily drive driven gear sliding sleeve 12 to rotate, enter
And drive bypass sliding sleeve 13 to rotate.
The 1st by-pass prot is formed with the side wall of bypass sliding sleeve 13, in the bottom of valve body 1 position corresponding with the 1st by-pass prot
Place is provided with the 2nd by-pass prot, and bypass plug 14 is blocked in the 2nd by-pass prot.When valve element 3 is opened, open the primary path in valve body 1
When, the 2nd by-pass prot and the 1st by-pass prot are staggered, and close the 1st by-pass prot；When rotating the knob 10, the driving gear
Rotation, and then drive the driven gear sliding sleeve 12 and bypass sliding sleeve 13 to be rotated about its center axis.
The ball valve includes the snap ring 6, spring 5, upper valve base 4, the valve element 3 that are from top to bottom sequentially arranged in valve body 1
With lower valve base 2, hole back-up ring 7 is installed in snap ring 6, the lower valve base 2 is arranged in driven gear sliding sleeve 12, under lower valve base 2
Sit up straight on the step for leaning against and being formed on the inwall of valve body 1, driven gear sliding sleeve 12 can rotate relative to valve body 1 and lower valve base 2.
Between the upper valve base 4 and valve body 1, between the lower valve base 2 and driven gear sliding sleeve 12, on the bypass sliding sleeve
Sealing ring is mounted between lower end and valve body 1 and between the bypass plug 14 and valve body 1.
In addition, diameter of the end diameter of the driving gear 11 more than the 1st by-pass prot；The 1st by-pass prot week
Metal sealing is housed between the outer wall of bypass sliding sleeve 13 and valve body 1 that enclose, sealing is improved.The driving gear 11 and driven gear
The crossed axis angle of the bevel gear of the upper end of sliding sleeve 12 is 90 °, is easy to transmit revolving force.
The operation principle of the continuous circulating valve of coordinated type of the invention is as follows：
In normal drilling, the valve element 3 on the continuous circulating valve top of coordinated type is in open mode, realizes opening for primary path
Open；By-pass prot on by-pass prot on bypass sliding sleeve 13 and valve body 1 is staggered certain angle, realizes the closing of bypass.
When single or column is unloaded, bypass plug 14 is removed, bypass pipeline is connected to the by-pass prot on valve body 1,
After the knob 10 of upper ball valve after primary path and bypass pressure balance, is rotated, the valve element 3 of ball valve starts to rotate, and makes primary path
Changed from open mode to closed mode, meanwhile, the driving gear 11 that rotarily drives of knob 10 is rotated, the rotation of driving gear 11
Driven gear sliding sleeve 12 is driven to be rotated around central shaft again, the rotation of driven gear sliding sleeve 12 drives bypass sliding sleeve 13 around its center
Axle is turned an angle so that the by-pass prot on bypass sliding sleeve 13 is alignd with the by-pass prot of valve body 1, so that it is logical to set up bypass circulation
Road；When needing to be again turned on primary path, closing bypass, knob 10 is reversely rotated.
