Abstract
The utility model discloses a valve for on oil development well head sleeve pipe, its characterized in that valve body and opener two parts can part, and the valve body is the single current valve structure, mainly comprises pressure spring and valve ball, and normal condition, valve ball make the valve body close under pressure spring's effect, and the opener is the tee bend body, with valve body threaded connection, and the opener center pin is equipped with the ejector pin, under its rear end top pushes away the control of nut, can push away the valve ball in the valve body, makes the valve open. The utility model has the advantages of small, no specialized tool can not be opened, can prevent that oil gas is stolen, can regard uses such as end cap, clamp head simultaneously, realizes multiple functions.
Description
The utility model discloses the well head servicing unit on a kind of oil exploitation facility, the effective valve of especially a kind of well head cover.
The valve that generally use in present oil field is the valve of a kind of model as KY250/65, mainly is made up of valve body, handwheel.Valve body is the tubular three-way body, and two ends are dops, can be connected with well head by clip; This valve is realized the open and close of valve body in use with the handwheel left rotation and right rotation.This kind valve, valve body and opening section are whole mechanisms, are easy to be opened, and so just cause oil gas often stolen; This valve volume is big in addition, uses, installs also inconvenient.
It is little that the purpose of this utility model provides a kind of volume, and valve body can separate with opening section and uses, a kind of valve that does not have the special tool valve body to be difficult for being opened, thus avoid oil gas often stolen.
For achieving the above object, the technical solution adopted in the utility model is, valve body can be used in combination or separate as required with opener two parts, valve body 1 tubular ectosome upper end is provided with upper chuck 2, and the inboard, middle part is provided with interior step 7, and the lower end is provided with lower contact 8, ball seat 6 is fixed on the interior step 7, valve ball 5 is withstood on the ball seat 6 by compression spring, and compression spring is glanded 3 and fixes, and this moment, valve body was closed; Opener 9 is a three-way body, and the upper end is provided with top connection 10, removably connects with lower contact 8 machineries of valve body, is connected with threeway 11 on the outer openings of middle part, and lower inside is provided with step 14, and the lower end undergauge is lower contact 16, and push rod 12 is contained in the axis position of opener; Nut 17 is threaded with lower contact 16.Normal condition, valve ball close valve body under the effect of compression spring; Under opener push rod 12 control of pushing tow nut in its back-end, can back down the valve ball in the valve body, make valve open.
The utility model uses owing to valve body can separate with opener, the ball-and-seat that valve body has adopted compression spring control valve ball to constitute, there is not special-purpose instrument not open, so just can prevent from effectively to steal oil gas by opening valve, reduced the volume of valve body simultaneously, have only 1/3 of former valve, through field trial, respond well.
Fig. 1, multi-functional clip head valve structural representation.
Below in conjunction with accompanying drawing, describe implementation process of the present utility model in detail.As shown in Figure 1, the utility model is made up of valve body 1 and opener 9 two parts.Valve body tubular ectosome upper end is provided with upper chuck 2, as connecting fixing with well head, there is screw thread the inboard, lower end, as lower contact 8, as with being connected of opener or other pipeline, the centre is provided with interior step 7, is used as fixed ball seat 6, valve ball 5 tightly is being stuck under the effect of compression spring 4 on the ball seat 6, and it is fixing that spring 4 upper ends are positioned at the gland 3 on tubular ectosome top.Opener is a threeway shape body, and there is screw thread in top connection 10 outsides, can be connected with the lower contact 8 of valve body; Be welded with threeway 11 in the middle of the opener on the outer openings, as draining gas, tipping instrument etc., a convex step 14 is arranged at the bottom; There are two road grooves 15 inboard of lower end undergauge, is used to place sealing ring, and effect is a sealing push rod 12, prevents overflowing of oil gas, and there is screw thread in the outside, as lower contact 16, as connecting with nut 17.Push rod 12 is contained in the axis position of opening body, is provided with boss 13 at it by position down, with 14 interactions of convex step, prevents from that push rod 12 from withdrawing to cause the accident.By the rotation of nut 17 in lower contact 16, order about seesawing of push rod 12, when push rod 12 backed down valve ball 5 forward, valve open, or directly connect other pipeline in valve body lower contact 8, water pressed off and open valve and carry out clean-out service; When nut 17 readjustments, ball valve 5 is being got back on the valve seat 6 valve-off under the effect of compression spring 4.Opener 9 is contained on the valve body 1 when using, and the time spent can not unloaded, and many mouthfuls of oil wells can a shared opener like this, makes the valve volume can dwindle 3/4.No opener valve is not opened, and can prevent that oil gas is stolen.When the utility model uses as head valve, also can be used as plug, the first-class use of clip, can realize multiple function.
