Description
Technical field
The utility model relates to a kind of oil field shaft mouth multi-function throttle valves.
Background technique
Oil field shaft mouth is to control flow by throttle valve in production, needs pressure break to increase after producing a period of time
When yield, fracturing fluid is injected into well by installing a check valve.
Summary of the invention
Purpose of the utility model is to solve the troubles that additionally mounted check valve is needed when fracturing work, provide one kind
Have both the multi-function throttle valve of throttling function and one-way function.
The purpose of this utility model solves by the following technical programs：
A kind of multi-function throttle valve, including valve body, it is characterised in that：Valve chamber, the valve chamber are equipped in the valve body
It is inside fixedly installed with valve seat, is equipped with the tapering that can block the spool of sprue on valve seat, the bar portion of spool can be embedded in valve
The setting of bar one end is set in hole, and the bar portion of spool can be fixed on and set by the limit screw for setting the side setting in hole
In hole；The lateral channel for being relatively orthogonal to valve rod is equipped at the valve chamber.
The lateral channel is located at the bar portion region of spool.
The lateral channel is not less than the upper edge of valve seat relative to the lower edge of valve seat.
The limit screw is located at the root area for setting hole.
The other end of the valve rod is provided with handwheel.
The utility model has the following advantages compared with prior art：
The utility model form a valve by using valve seat, spool and valve rod and controlled using limit screw valve rod and
State between spool realizes throttling function or one-way function according to different requirements, passes through the use of the multi-function throttle valve, energy
The labor intensity of worker is enough effectively reduced, production cost is reduced, improves production efficiency and increase economic benefit.
Detailed description of the invention
Structural schematic diagram when attached drawing 1 is the throttle of the multi-function throttle valve of the utility model；
Structural schematic diagram when attached drawing 2 is the unidirectional state of the multi-function throttle valve of the utility model.
Wherein：1-valve body；2-valve chambers；3-valve seats；4-sprues；5-spools；6-valve rods；7-set hole；8—
Limit screw；9-lateral channels；10-handwheels.
Specific embodiment
The utility model is further described with embodiment with reference to the accompanying drawing.
As shown in Figs. 1-2：A kind of multi-function throttle valve, including valve body 1 are equipped with valve chamber 2 in valve body 1, fix in valve chamber 2
Valve seat 3 is installed, is equipped with the tapering that can block the spool 5 of sprue 4 on valve seat 3, the bar portion of spool 5 can be embedded in valve rod
The setting of 6 one ends is set in hole 7, and the bar portion of spool 5 can be fixed on by the limit screw 8 for setting the side setting in hole 7
It sets in hole 7；And the lateral channel 9 for being relatively orthogonal to valve rod 6 is equipped at valve chamber 2, which is located at the bar of spool 5
Portion region and lateral channel 9 are not less than the upper edge of valve seat 3 relative to the lower edge of valve seat 3.In above-mentioned multi-function throttle valve, stop
Screw 8 is located at this and sets the root area in hole 7, and the other end of valve rod 6 is provided with handwheel 10.
The multi-function throttle valve of the utility model is in use, as shown in Figure 1：When needing throttling function, stop is first tightened
Screw 8 makes valve rod 6 and spool 5 be linked to be entirety, and then the gap of 10 adjusting spool 5 of rotation hand wheel and valve seat 4 is achieved that throttling
Function.As shown in Figure 2：When needing one-way function, limit screw 8 is first unclamped, separates valve rod 6 and spool 5, rotation hand wheel
10 make valve rod 6 be moved to topmost, in this way, spool 5 can freely move up and down, fluid also can only from 4 lower part of sprue into
Enter, realizes one-way function.
The utility model forms a valve and using limit screw 8 by using valve seat 4, spool 5 and valve rod 6 come control valve
State between bar 6 and spool 5 realizes throttling function or one-way function according to different requirements, passes through the multi-function throttle valve
It uses, the labor intensity of worker can be effectively reduced, production cost is reduced, improve production efficiency and increase economic benefit.
Above embodiments are only to illustrate the technical idea of the utility model, and the protection model of the utility model cannot be limited with this
Enclose, it is all according to the utility model proposes technical idea, any changes made on the basis of the technical scheme each falls within this reality
Within the scope of novel protected；The technology that the utility model is not directed to can be realized by the prior art.
