Abstract
The utility model discloses a double-element integrated valve. The double-element integrated valve solves the problem that when a valve element of an existing stop valve of a well mouth of an oil-water well is replaced, well killing is needed. The double-element integrated valve comprises a valve body, a stop valve element, a ball valve seat and a ball valve element. A stop valve seat is arranged in the valve body. The stop valve element, a stop valve element opening and closing assembly, a stop valve deck and a sealing assembly are arranged in the valve body and are matched with the stop valve seat. The ball valve seat, the ball valve element, a ball valve element opening and closing assembly, a pressing cap and a sealing assembly are further arranged in a fluid channel which is arranged between the stop valve seat and a valve body inlet in the valve body, wherein the ball valve element, the ball valve element opening and closing assembly, the pressing cap and the sealing assembly are matched with the ball valve seat. A right-angle channel is formed in the ball valve element. An outlet of the right-angle channel is communicated with the stop valve seat. The double-element integrated valve is convenient to install and maintain, and capable of shortening the idling period and reducing the loss of crude output.
Description
Technical field
The utility model relates to a kind of novel valve.
Background technique
Stop valve plays a leading role in field produces, is the control valve that each pipe network flow process and oil/water well well head must be installed,
Because existing stop valve has a groove sealing mutually with valve body at the place of closing of flashboard, so no matter how valve is installed, owing to containing partial impurities (sand, wax) in oil well well liquid, when flowing through groove, will be trapped in groove, thereby cause the not appearance of tight phenomenon of valve closing.The oil/water well well head in oil field need to be installed 5 250 model stop valves; this 250 model stop valve in use often can sting because being not closed completely bad spool; spool cannot keep in repair after being stung badly; can only change; during replacing, need again kill-job; so not only affect well yield, also the cost of use of increase equipment etc., strengthens employee's labor intensity.
Summary of the invention
The utility model provides a kind of twin-core integral type valve, uses this valve, and under the state without kill-job, replaceable spool, has shortened the replacing time, has avoided waste of material.
For achieving the above object, the technical solution adopted in the utility model is: twin-core integral type valve, comprise valve body, cut-off spool, ball seat and ball valve core, cut-off valve seat is set in described valve body, and arrange with this and end the supporting cut-off spool of valve seat, cut-off spool opening/closing component, break valve cover and black box, in fluid course in valve body between cut-off valve seat and valve body entrance, also insert ball seat, and arrange and ball valve core that this ball seat is supporting, ball valve core opening/closing component, pressure cap and black box, in described ball valve core, right angle channel is set, the outlet of this right angle channel communicates between valve seat with cut-off.
The beneficial effects of the utility model:
1, this valve can be saved cost of material;
2, this valve installation is convenient, and maintenance is convenient, reduces employee's labor intensity;
3, this valve can shorten the off-time, reduces the loss of crude output.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model twin-core integral type valve.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1: twin-core integral type valve, comprise valve body 8, cut-off spool 6, ball seat 9 and ball valve core 10, the interior cut-off valve seat 7 that arranges of described valve body 8, and arrange with this and end the supporting cut-off spool 6 of valve seat 7, cut-off spool opening/closing component, break valve cover 4 and stop valve black box 3, wherein end spool opening/closing component, comprise valve rod 5 and handwheel 1, on break valve cover 4, be stamped gland 2, above-mentioned cut-off valve seat 7 and cut-off spool 6, cut-off spool opening/closing component, break valve cover 4 and stop valve black box 3 form stop valve, this stop valve is identical with conventional stop valve structure, difference is, fluid course between cut-off valve seat 7 in valve body 8 and the entrance of valve body 8 is built-in enters ball seat 9, and arrange and ball valve core 10, ball valve core opening/closing component 12, pressure cap 13 and black box 14 that this ball seat 9 is supporting, the interior right angle channel 11 that arranges of described ball valve core 10, the outlet of this right angle channel 11 communicates between valve seat 7 with cut-off.
This valve is applicable to each pipe network and oil/water well application at present, and boundary dimension is measure-alike with the original stop valve using, and can realize exchange.During normal production, the cut-off spool of top and the ball valve core of below are all opening state, in case of handling failure can be closed the stop valve spool of top, and close after utilizing lower ball valve emptying, then change cut-off spool, and Renewal process is without kill-job.
Claims (1)
1. twin-core integral type valve, comprise valve body, cut-off spool, ball seat and ball valve core, cut-off valve seat is set in described valve body, and arrange with this and end the supporting cut-off spool of valve seat, cut-off spool opening/closing component, break valve cover and black box, it is characterized in that: in the fluid course in described valve body between cut-off valve seat and valve body entrance, also insert ball seat, and arrange and ball valve core that this ball seat is supporting, ball valve core opening/closing component, pressure cap and black box, in described ball valve core, right angle channel is set, the outlet of this right angle channel communicates between valve seat with cut-off.
