Abstract
The utility model discloses a picking and pressing valve of the water injection well of the oil well in the oil field, with the structural key points that a valve needle is arranged in the valve body, and a welded joint connected with pipes is arranged at the lower part of the valve body, the joint of the picking and pressing appearance is vertical with the axes of the valve needle. The utility model is capable of being conveniently fixed at the new or old pipes, and protected by a helmet and a locking ring; the utility model is capable of being used outdoors, safely and reliably; laypeople is incapable of operating the utility model; the part below the valve needle in the valve body is dissolved in the liquid, having a function of frost protection; and the pressure measuring apparatus is fast and convenient to be assembled and disassembled.
Description
The utility model belongs to the machinery valve technical field, and particularly a kind of oilfield water injection well is adopted pressure valve.
Adopting in the pressure process at the oilfield water injection well at present, general working pressure table switch (stop valve), it comprises valve body, spool, handwheel, Sealing.Because inlet and outlet connectors adopts be threaded (tapered thread sealing or copper packing sealing are adopted in sealing), needs inipple when installing and using; Difficulty is installed on old pipeline; Because how in the open air operation has the joint late gate easily to cause liquid to freeze away from pipeline and can not adopt pressure; Adopt the sealing of thread seal or copper packing to be difficult for being connected fast with pipeline; Movable member on the valve exposes, and is dangerous under high pressure, runnability; Valve connects the loading and unloading difficulty with the pressure measurement instrument.
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provides a kind of easy for installation, can use out of doors and safe and reliable, can adopt pressure valve with the oilfield water injection well of the quick and convenient loading and unloading of pressure measurement instrument.
For achieving the above object, the solution that the utility model adopts is, it comprises the needle that is assemblied in the valve body, between the surface of contact of valve body and needle, be provided with seal ring, be characterized in: needle presses the joint axis of instrument to become plumbness with adopting, and is equipped with the soldered splice that can link with pipeline in the outer periphery of valve body lower end.
The outer periphery of needle of the present utility model is equipped with protective hat.
The turn end of needle of the present utility model is the regular polygon that is no less than three limits.
The upper end of soldered splice of the present utility model is provided with the locking circle.
Locking circle of the present utility model is the regular polygon that is no less than three limits.
Working principle of the present utility model is as follows: with the turn end of instrument twisting needle, needle rises thereupon, and the passage that liquid links by needle lower end and pipeline enters adopts pressure device, adopt press finish after, twist the turn end throttle down of needle.
The utility model can both conveniently install, have protective hat and the protection of locking circle on new (old) pipeline; can use out of doors, position safe and reliable, that the layman can not operate, the valve body inner valve needle is following dissolves in liquid; can play antifreeze effect, the loading and unloading of pressure measurement instrument are quick and convenient.
Fig. 1 is a structure principle chart of the present utility model.
Below in conjunction with accompanying drawing structural principle of the present utility model and working principle are described in further detail.
Referring to Fig. 1.The utility model is by the soldered splice 1 that is arranged on periphery, valve body 3 lower end and be provided with that needles 5 in the valve body 3 form.Soldered splice 1 welding of on body, punching; link with body; be provided with the regular polygon retainer 2 that is no less than three limits in the upper end of soldered splice 1; with soldered splice 1 welding; prevent valve body 3 loosening and dismountings easily; needle 5 is installed in the valve body 3; needle 5 is provided with seal ring 6 with the surface of contact of valve body 3; needle 5 becomes plumbness with joint 7 axis of adopting the pressure instrument; the turn end of needle 5 is the regular polygon that is no less than three limits; the outer periphery of needle 5 is equipped with protective hat 4, is used to protect inner needle, nut, Sealing etc.With the turn end of instrument twisting needle, needle rises thereupon, and the passage that liquid links by needle lower end and pipeline enters adopts pressure device, adopt press finish after, twist the turn end throttle down of needle.
