Description
Technical field
The utility model relates to straight-through adjustable restrictor for a kind of production wellhead.
Background technology
At present, many flowing wells need rationally to control oil well production pressure differential in the process of opening well and making production, for avoiding oil nozzle bore dia little, make wellhead flowline pressure-bearing too large; Oil nozzle bore dia is excessive, can cause shaft bottom excitement to cause formation sand production.So need to change in time the oil nozzle of different pore size.The oil nozzle of field by using is all isolated at present, and each replacing need to be closed production valve, pressure release, and then change.Execute-in-place trouble, workload is large.
Summary of the invention
The purpose of this utility model is to change troublesome poeration, drawback that workload is large for existing production wellhead oil nozzle, provides a kind of by regulating the through hole of the adjustable plate straight-through adjustable restrictor that connect area adjust oil mass relative to the through hole of fixed head.
The purpose of this utility model solves by the following technical programs:
A kind of straight-through adjustable restrictor, comprise interconnective valve gap and valve body, it is characterized in that the oil outlet corresponding and coaxially setting mutually on fuel feed hole and the valve body on described valve gap, in the inner chamber that valve gap and valve body form, be provided with the fixed head being fixed on valve body, a side at fixed head is provided with the adjustable plate of locating by trunnion shaft, on fixed head and adjustable plate, be all provided with through hole on through hole and fixed head mutually corresponding with oil outlet, the screw rod that the edge of adjustable plate arranges with one side engages and is connected, and one end of screw rod is connected with the turning cylinder that stretches out the handwheel outside valve body.
One end of described trunnion shaft embeds in fixed head and is connected with fixed head by bearing, and the other end of trunnion shaft embeds in valve gap and is connected with valve gap by bearing.
Between the end, one end of described trunnion shaft embedding valve gap and valve gap, be provided with spring.
Described handwheel is fixed on valve body by gland.
Described turning cylinder is arranged in valve body by filler and gland sealing.
The utility model has the following advantages compared to existing technology:
The utility model drives screw rod by rotating handwheel, and drive and engage connected adjustable plate with it by screw rod, thereby the relative coincidence area between the through hole on through hole and fixed head on change adjustable plate, thus flow area regulated quickly and easily, reach the object of rational production control; The fuel feed hole of this restriction choke and oil outlet are straight-through is simultaneously conducive to reduce fluid to the washing away of valve body, and improves the application life of valve body; This restriction choke compact conformation, easy for installation, has cancelled while changing common oil nozzle and has closed production gate valve, and the course of work that pressure release, emptying etc. are complicated, has alleviated workman's labour intensity; And safe and convenient to use, simple to operate, effectively save production cost, improve production efficiency and increased economic benefit.
