Description
Technical field
The utility model relates to and a kind of conventional flat-panel valve.
Background technique
Flap type is widely applied on the well-control equipment of oil drilling.Flap type is generally made up of parts such as seal, sealing cover, valve body, valve gap, piston, valve rod, valve plate, valve seat and wavy springs.By applying hydraulic pressure in outer bound pair seal, driven plunger moves, and piston connects valve rod, and valve rod drives valve plate to move up and down in valve channel Vertical direction, thus realizes the Kai Heguan of valve.The deficiency that traditional common flap type exists is: piston, in the moving process driving valve plate, due to coaxality and the balance of very difficult guarantee valve plate, valve rod, piston, easily occurs stuck, is unfavorable for that the timely and effective operation of well-control equipment is closed; In closed procedure, directly cannot know the closedown degree in valve passage hole, can only indirectly understand valve by flow and whether close and put in place, operation and inconvenient rate.
Model utility content
For solving the problems of the technologies described above, we have proposed a kind of flap type, in effective solution conventional construction switching process, valve plate easily stuck, the not simple and clear difficult problem of operation, has the features such as modern design, easy to operate, reliable performance, is suitable for various oil drilling well-control equipment.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of conventional flat-panel valve, it is characterized in that, comprise end cap, end bar, valve body, seal ring, valve seat, valve plate, valve gap, valve rod, adpting flange, seal, piston, sealing cover and positioning rod, sealing cover is bolted at the top of seal, sealing cover cylindrical has elongated slot on four equal cloth beams, under shed is opened in the bottom that upper shed seal is opened on the top of seal, bottom and the valve gap upper end of seal are connected and fixed by adpting flange, valve gap lower end and valve body upper flange are fixed by bolt and nut, valve body lower flange and end cap are fixed by bolt and nut, piston is arranged in seal, piston is by the upper end of nut check at valve rod, piston upper end is fixedly connected with positioning rod by nut, be fixedly connected with valve plate one end in the valve pocket that valve body is stretched in the lower end of valve rod, valve plate both sides are respectively provided with a seal ring and valve seat, the other end of valve plate is fixedly connected with end bar.
The utility model effectively to solve in conventional construction switching process valve plate easily stuck, the not simple and clear difficult problem of operation, has the features such as modern design, easy to operate, reliable performance, is suitable for various oil drilling well-control equipment.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the sectional view of a kind of conventional flat-panel valve disclosed in the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment
As shown in Figure 1, this flap type is by end cap 1, end bar 2, U-shaped filler 3, valve body 4, seal ring 5, valve seat 6, valve plate 7, valve gap 8, valve rod 9, adpting flange 10, seal 11, piston 12, sealing cover 13, positioning rod 14 is formed, sealing cover 13 is bolted at the top of seal 11, sealing cover 13 cylindrical has elongated slot on four equal cloth beams, upper shed 15 is opened on the top of seal 11, under shed 16 is opened in the bottom of seal 11, bottom and valve gap 8 upper end of seal 11 are connected and fixed by adpting flange 10, valve gap 8 lower end and valve body 4 upper flange are fixed by bolt and nut, valve body 4 lower flange and end cap 1 are fixed by bolt and nut, piston 12 is arranged in seal 11, piston 12 is by the upper end of nut check at valve rod 9, piston 12 upper end is fixedly connected with positioning rod 14 by nut, be fixedly connected with valve plate 7 one end in the valve pocket that valve body 4 is stretched in the lower end of valve rod 9, valve plate 7 both sides are respectively provided with a seal ring 5 and valve seat 6, the other end of valve plate 7 and hold bar 2 to be fixedly connected with.Wherein, U-shaped filler 3 is filled between end cap 1 and end bar 2.Working principle of the present utility model is: promote piston 12 by upper shed 15, under shed 16 injection liquid force feed, make piston 12 drive the valve plate 7 be connected with valve rod 9 to move up and down, thus switch valve makes liquid pass through or ends; When valve plate 7 move up put in place time, seal ring 5 and valve seat 6 endoporus on the endoporus on valve plate 7 and both sides are connected, and valve plate 7 is opening state; Put in place when valve plate 7 moves down, seal ring 5 and valve seat 6 endoporus on the endoporus on valve plate 7 and both sides misplace completely, and namely seal ring 5 and valve seat 6 bore passage are intercepted by the entity on valve plate 7, and valve plate 7 is closed condition.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
