Description
Technical field
The present invention relates to the well control equipment related in Oil-Gas Well Engineering field, particularly a kind of visualization device being easy to observe manual flat valve open/close states.
Background technology
At present, in Oil/gas Well well control equipment, particularly in choke manifold, manual flat valve is as core component. When manual flat valve carries out being turned on and off operating, decide the circulation status (go out stream or block) of borehole fluid. When manual flat valve opens and closes incomplete, the particularly not fully closed situation forming flowing gap of flashboard, the direct impact of high-voltage high-speed borehole fluid can be subject to, cause flap type to tremble, valve plate ruptures even valve body thorn leakage, there is serious potential safety hazard.
The detecting device of conventional rising stem type manual flat valve open/close states, is installed the guard shield with observation port additional at top. The proud exposure of guard shield inner valve stem is observed, it is possible to substantially judge the open/close states of flap type by observation port.
There are the following problems for this detecting device: (such as night etc.) under low-light (level) working environment, the proud exposure being observed guard shield inner valve stem by observation port is very difficult, can not judge degree that flap type opens and closes (such as: fully open, completely close, half-open half pass etc.) accurately simultaneously; (such as Gobi desert, desert etc.) under harsh weather working environment, it is impossible to be effectively prevented sand and dust and invade, cause that valve rod rotation difficulty, valve plate open and close malfunctioning.
Therefore; need the detecting device of rising stem type manual flat valve open/close states is carried out technological innovation; it is not only able to make operator and patrol officer can carry out looking at straight, accurately detecting flap type keying degree; it also is able to be effectively protected the threaded stem of exposure; guarantee that flap type open/close states meets Oil/gas Well well control technique requirement all the time, evade well control safety risk.
Summary of the invention
It is an object of the invention to overcome the shortcoming of prior art, it is provided that a kind of compact conformation, good dustproof effect, can use under low light conditions, can accurately read flap type opening degree be easy to observe manual flat valve open/close states visualization device.
The purpose of the present invention is achieved through the following technical solutions: a kind of visualization device being easy to observe manual flat valve open/close states, and it includes indicator, guard shield and visualization dust cover;
Described indicator is by pointer, swivel becket, locking nut and multidiameter composition, pointer is provided with through hole I, multidiameter is by the axle I being linked in sequence and the diameter of axle increases successively, axle II and axle III composition, screwed hole A it is provided with in multidiameter, axle I is provided with external screw thread, axle III is provided with screwed hole B, swivel becket is enclosed within axle II and locking nut is threadeded with axle I, pointer is horizontally disposed with and is fixed on swivel becket through screw A through through hole I, the screwed hole A of multidiameter is connected with threaded stem and screws in stem bottom, multidiameter is fastened on valve rod through screw B and screwed hole B,
Described guard shield cylinder is provided with through hole chute II, bottom is provided with screwed hole C, the upper and lower two ends of cylinder are provided with screwed hole D, the screwed hole C of guard shield is threadeded with valve rod base, valve rod and indicator all cover in guard shield, and pointer via through holes chute II is through guard shield and is horizontally disposed with at through hole chute II inner surface;
The cylinder of described visualization dust cover arranges through hole III, the cylinder of visualization dust cover is additionally provided with the full-gear graduation mark and full-shut position graduation mark that are parallel to pointer, midpoint between full-gear graduation mark and full-shut position graduation mark is half-open position graduation mark, the full-gear graduation mark distance from full-shut position graduation mark is equal to the haul distance of valve rod, and the distance that full-gear graduation mark is from full-shut position graduation mark is divided into ten lattice, the distance of every lattice is the 10% of flap type aperture, when valve plate is under full-shut position, pointer is on full-shut position graduation mark, when under valve plate is shown in a fully open operation, pointer is shown in a fully open operation on graduation mark, full-shut position graduation mark is provided above optimal closed state graduation mark.
Described visualization dust cover is enclosed within guard shield, and is each passed through through hole III and screwed hole D through two screw C and is fastened on guard shield, forms closed structure, valve rod and valve seat are played protection.
Described full-gear graduation mark is green groove, and full-shut position graduation mark is red groove, and half-open position graduation mark is yellow groove, and optimal closed state graduation mark is orange groove.
Groove and half-open position graduation mark between described full-gear graduation mark and half-open position graduation mark are black gradations with full-shut position graduation mark.
The invention have the advantages that (1) full-gear graduation mark, full-shut position graduation mark, half-open position graduation mark and optimal closed state graduation mark are by different color compositions, therefore, under low-light (level) working environment, read its position on graduation mark by looking at pointer straight, just can detect that flap type opens and closes degree accurately. (2) valve rod of exposure of the present invention is in the guard shield of closing all the time, invades therefore, it is possible to be effectively prevented sand and dust, has the feature of good dustproof effect. (3) the optimal closed state graduation mark that virtualized location graduated disc is demarcated, can require according to Oil/gas Well well control technique (to ensure that when flap type cuts out, valve plate is in quick condition, 1/4 ~ 1/2 circle must be turned round after closedown), flap type is controlled to fully closed optimum Working.
