Abstract

The invention discloses an oil-controlled flat valve. The top of the cylinder body is fixed with a cylinder cover; the outer circle of the cylinder cover is provided with four on-shaft elongated slots which are uniformly distributed; the bottom of the cylinder body is connected and fixed with the upper end of a valve cap; the lower end of the valve cap is fixed with a valve body upper flange; a valve body lower flange is fixed with a tail cover; a piston is arranged in the cylinder body and locked to the upper end of a valve stem; the upper end of the piston is fixedly connected with an indicator rod; the lower end of the valve stem extends into a valve cavity of the valve body and is fixedly connected with one end of a valve plate; and the other end of the valve plate is fixedly connected with a tail rod. The oil-controlled flat valve is simple in structure and convenient to operate, has reliable performance, solves the problems of easy jamming of the valve plate and non-visual operation in the switching process, and is suitable for various petroleum drilling well-control facilities.

Description

Liquid-operated flat valve

Technical field

The invention belongs to valve technology field, specifically, relate to a kind of liquid-operated flat valve.

Background technique

Liquid-operated flat valve is widely applied on the well-control equipment of oil drilling.Tradition liquid-operated flat valve is generally made up of parts such as gray iron, valve body, valve gap, piston, valve rod, valve plate, valve seat and wavy springs.By applying hydraulic pressure in outer bound pair cylinder body, 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 tradition liquid-operated flat valve exists is: 1, piston is 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 the timely and effective operation of well-control equipment.2, in closing process, 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.

Summary of the invention

The object of the invention is to: a kind of liquid-operated flat valve is provided, valve plate easily stuck, the not simple and clear difficult problem of operation in effective solution conventional construction switching process, there is the features such as novel in design, easy to operate, reliable performance, be suitable for various oil drilling well-control equipment.

Technical solution of the present invention is as follows: this flap type is by tail-hood, foot piece, U-shaped filler, valve body, seat ring 5, valve seat, valve plate, valve gap, valve rod, adpting flange, cylinder body, piston, cylinder cap, indicating arm is formed, cylinder cap is bolted at the top of cylinder body, cylinder cap cylindrical has elongated slot on four equal cloth beams, filler opening is opened on the top of cylinder body, lower filler opening is opened in the bottom of cylinder body, bottom and the valve gap upper end of cylinder body 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 tail-hood are fixed by bolt and nut, piston is arranged in cylinder body, piston is by the upper end of nut check at valve rod, piston upper end is fixedly connected with indicating arm 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 seat ring and valve seat, the other end of valve plate is fixedly connected with foot piece.

Wherein, U-shaped filler is installed between tail-hood and foot piece.

The present invention has the following advantages:

1, on cylinder cap cylindrical, have elongated slot on four equal cloth beams, observe indicating arm position by elongated slot, and then know the closedown situation of valve plate, conveniently instruct operation.

2, between tail-hood and foot piece, fill U-shaped filler, in the process of piston actuated valve plate motion, foot piece plays well guiding and balanced action, ensure that the switch of liquid-operated flat valve is smooth and easy, can obtain reliably Safety performance and longer working life.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Embodiment

Below in conjunction with accompanying drawing, the invention will be further described.

As shown in Figure 1, this flap type is by tail-hood 1, foot piece 2, U-shaped filler 3, valve body 4, seat ring 5, valve seat 6, valve plate 7, valve gap 8, valve rod 9, adpting flange 10, cylinder body 11, piston 12, cylinder cap 13, indicating arm 14 is formed, cylinder cap 13 is bolted at the top of cylinder body 11, cylinder cap 13 cylindrical has elongated slot on four equal cloth beams, filler opening 15 is opened on the top of cylinder body 11, lower filler opening 16 is opened in the bottom of cylinder body 11, bottom and valve gap 8 upper end of cylinder body 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 tail-hood 1 are fixed by bolt and nut, piston 12 is arranged in cylinder body 11, piston 12 is by the upper end of nut check at valve rod 9, piston 12 upper end is fixedly connected with indicating arm 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 seat ring 5 and valve seat 6, the other end of valve plate 7 is fixedly connected with foot piece 2.

Wherein, U-shaped filler 3 is filled between tail-hood 1 and foot piece 2.

Working principle of the present invention is: promote piston 12 by upper filler opening 15, lower filler opening 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, seat 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, seat ring 5 and valve seat 6 endoporus on the endoporus on valve plate 7 and both sides misplace completely, and namely seat ring 5 and valve seat 6 bore passage are intercepted by the entity on valve plate 7, and valve plate 7 is closed condition.

To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.
