Description

The modified model flap type that surges

Technical field

The utility model belongs to valve technology field, specifically, relates to a kind of modified model flap type that surges.

Technical background

The flap type that surges is widely applied on the well-control equipment of oil drilling.The tradition flap type that surges generally is made up of parts such as cylinder body, cylinder cap, valve body, valve gap, piston, valve rod, valve plate, valve seat and wavy springs.Through applying hydraulic pressure in the outer bound pair cylinder body, driven plunger moves, and piston connects valve rod, and valve rod drives valve plate and moves up and down in the valve channel Vertical direction, thereby realizes the Kai Heguan of valve.The tradition deficiency that flap type exists of surging is:

1, piston is in driving the moving process of valve plate, owing to be difficult to guarantee the coaxality and the balance of valve plate, valve rod, piston, occurs stuckly easily, is unfavorable for the timely and effective operation of well-control equipment.

2, close in the closed procedure, can't directly know the degree of closing in valve passage hole, can only understand valve indirectly through flow and whether close and put operation and inconvenient in place.

Summary of the invention

The purpose of the utility model is: a kind of modified model flap type that surges is provided; Effectively solve stuck easily, the not simple and clear difficult problem of operation of valve plate in the conventional construction switching process; Have characteristics such as novel in design, easy to operate, reliable performance, be suitable for various oil drilling well-control equipments.

The technical solution of the utility model is following: this flap type is made up of tail-hood, foot piece, U type filler, valve body, seat ring 5, valve seat, valve plate, valve gap, valve rod, adpting flange, cylinder body, piston, cylinder cap, indicating arm; The bolt cylinder cap is passed through at top at cylinder body, is having elongated slot on four equal cloth beams on the cylinder cap cylindrical, and filler opening is opened on the top of cylinder body; Filler opening is opened down in the bottom of cylinder body; The bottom of cylinder body is connected through adpting flange with the valve gap upper end to be fixed, and valve gap lower end and valve body upper flange are fixed through bolt and nut, and valve body lower flange and tail-hood are fixed through bolt and nut; Piston is arranged in the cylinder body; Piston is through the upper end of nut check at valve rod, and the piston upper end is fixedly connected indicating arm through nut, and the lower end of valve rod is stretched in the valve pocket of valve body and with valve plate one end and is fixedly connected; The valve plate both sides respectively are provided with a seat ring and valve seat, and the other end of valve plate is fixedly connected with foot piece.

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

The utlity model has following advantage:

1, having elongated slot on four equal cloth beams on the cylinder cap cylindrical, observing the indicating arm position, and then knowing the situation of closing of valve plate, making things convenient for guiding operation through elongated slot.

2, dress U type filler between tail-hood and foot piece, in the process of piston actuated valve plate motion, foot piece plays good guiding and balanced action, and the switch of the flap type that guaranteed to surge is smooth and easy, can obtain Safety performance and long working life reliably.

Fig. 1 is the structural representation of the utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further.

As shown in Figure 1, this flap type is made up of tail-hood 1, foot piece 2, U type 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, passes through bolt cylinder cap 13 at the top of cylinder body 11; Having elongated slot on four equal cloth beams on cylinder cap 13 cylindricals; Filler opening 15 is opened on the top of cylinder body 11, and filler opening 16 is opened down in the bottom of cylinder body 11, and the bottom of cylinder body 11 is connected fixing with valve gap 8 upper ends through adpting flange 10; Valve gap 8 lower ends and valve body 4 upper flanges are fixed through bolt and nut; Valve body 4 lower flanges and tail-hood 1 are fixed through bolt and nut, and piston 12 is arranged in the cylinder body 11, and piston 12 is through the upper end of nut check at valve rod 9; Piston 12 upper ends are fixedly connected indicating arm 14 through nut; The lower end of valve rod 9 is stretched in the valve pocket of valve body 4 and with valve plate 7 one ends and is fixedly connected, and valve plate 7 both sides respectively are provided with a seat ring 5 and valve seat 6, and the other end of valve plate 7 is fixedly connected with foot piece 2.

Wherein, dress U type filler 3 between tail-hood 1 and the foot piece 2.

The working principle of the utility model is: through last filler opening 15, filler opening 16 injects hydraulic oil and promotes pistons 12 down, make piston 12 drive the valve plate 7 that is connected with valve rod 9 and move up and down, thereby switch valve passes through liquid or ends; When valve plate 7 moves up when putting in place, endoporus on the valve plate 7 and the seat ring on both sides 5 are connected with valve seat 6 endoporus, and valve plate 7 is an opening state; Put in place when valve plate 7 moves down, endoporus on the valve plate 7 and the seat ring on both sides 5 misplace with valve seat 6 endoporus fully, and promptly seat ring 5 is intercepted by the entity on the valve plate 7 with valve seat 6 interior hole paths, and valve plate 7 is a closed condition.
