Abstract
The utility model provides an uniflow stop valve. Main solve current uniflow stop valve function singleness, can only the control flow to the problem that can not close. Its characterized in that: being connected with valve pipe (2) under valve body (1), having a liquid hole on valve pipe (2) lateral wall, valve pipe (2) are connected with disk seat (6) down, have the feed liquor hole on disk seat (6), are connected with on valve body (1) valve cap (3), and valve cap (3) upward have valve rod (4) through threaded connection, and valve rod (4) sliding connection down have case (5), and case (5) are the shape of falling T, and cooperate with disk seat (6) case (5), has put the spring outside case (5) and between valve body (1). This uniflow stop valve have can the control flow to the characteristics that can close again.
Description
Technical field：
This utility model is related to the valve used by field of oil field oil extraction well head, especially unidirectional flow shutoff valve core.
Background technology：
In field of oil field oil extraction, unidirectional flow shutoff valve is installed on well head, controls well liquid one-way flow.And it is existing unidirectional
There is single function due to reasons in structure in flow shutoff valve, can only control to flow to the problem that can not be closed, pass must be equipped with well head
Valve closing door so that shaft collar and complex operation, affects oil recovery efficiency.
Utility model content：
In order to solve existing unidirectional flow shutoff valve single function, can only control to flow to the problem that can not be closed.This practicality is new
Type provides a kind of unidirectional flow shutoff valve core.The unidirectional flow shutoff valve core have i.e. controllable flow to again can close the characteristics of.
The technical solution of the utility model is：The unidirectional flow shutoff valve core includes valve body, valve pipe, bonnet, valve rod and valve element.
Valve pipe is connected with valve body, is had liquid outlet on valve tube side wall, under valve pipe, is connected with valve seat, have inlet opening on valve seat, connect on valve body
Bonnet is connected to, valve rod on bonnet, has been threaded connection, valve rod lower slider is connected with valve element, and valve element is inverted T-shaped, valve element and valve seat
It is engaged, valve element is outer to be equipped with spring and valve body between.
This utility model has the advantages that：The unidirectional flow shutoff valve core due to using valve pipe is connected with valve body,
There is liquid outlet on valve tube side wall, under valve pipe, be connected with valve seat, on valve seat, have inlet opening, on valve body, be connected with bonnet, lead on bonnet
Cross and be threaded with valve rod, valve rod lower slider is connected with valve element, valve element is inverted T-shaped, valve element is engaged with valve seat, valve element is outer and valve
The structure of spring is equipped between body.Thus realize that the unidirectional stream of control can be closed again, and simple structure.Thus the unidirectional stream cuts
Only valve element have i.e. controllable flow to again can close the characteristics of.
Description of the drawings：
Accompanying drawing 1 is this utility model structural representation.
1- valve bodies in figure, 2- valve pipes, 3- bonnets, 4- valve rods, 5- valve elements, 6- valve seats.
Specific embodiment：
The utility model is described in further detail below in conjunction with the accompanying drawings：
By shown in accompanying drawing, the unidirectional flow shutoff valve core includes valve body 1, valve pipe 2, bonnet 3, valve rod 4 and valve element 5.Under valve body 1
Valve pipe 2 is connected with, is had liquid outlet on 2 side wall of valve pipe, under valve pipe 2, is connected with valve seat 6, have inlet opening on valve seat 6, connect on valve body 1
Bonnet 3 is connected to, valve rod 4 on bonnet 3, has been threaded connection, 4 lower slider of valve rod is connected with valve element 5, valve element 5 is inverted T-shaped, valve element
5 are engaged with valve seat 6, and valve element 5 is outer to be equipped with spring and valve body 1 between.Existing stream is ended integral valve by the unidirectional flow shutoff valve core
Core changes over two bodies, valve rod 4 and valve element 5, and middle spring connects, and the valve element 5 after change is acted on individual event flow control, in rotation
5 dieback of valve element can be played stopping effect during rotating valve rod 4.
When actually used, the unidirectional flow shutoff valve core be arranged on well head and normally can be used.In normal operation
Under, when well liquid pressure is more than the elastic force of spring between valve element 5 and valve body 1, well liquid backs down valve element 5 upwards, and well liquid is by valve seat 6
Inlet opening enter, then by 2 side wall of valve pipe liquid outlet flow out.When well liquid pressure is less than spring between valve element 5 and valve body 1
During elastic force, the inlet opening on valve seat 6 is closed by valve element 5.Or the well liquid flowed into by the liquid outlet on 2 side wall of valve pipe also cannot be by valve
Inlet opening liquid on seat 6 goes out, it is ensured that unidirectional to flow.When closing well is needed, rotary valve rod 4,4 rotating down pressing spring of valve rod, while will
5 top pressure of valve element is on valve seat 6, and then realizes closing function.
