Abstract
The invention discloses a visual device convenient for observing the opening and closing states of a hand-operated flat valve. The visual device comprises an indicator (1), a shield (2) and a visual dust cover (3); the indicator (1) is mounted on a valve rod and then the shield (2) is mounted on a valve seat, and finally, the visual dust cover (3) sleeves the shield (2) to form an airtight structure; flat valve opening/closing state scale marks are formed on the visual dust cover (3); when the valve rod is rotated to open or close the flat valve, the indicator (1) moves upward or downwards along with the valve rod, and the opening degree of the flat valve can be read accurately by directly viewing the position of a pointer (4) on the scale marks. The visual device convenient for observing the opening and closing states of the hand-operated flat valve is capable of observing the opening and closing states of the hand-operated flat valve under the condition of a low illumination level and accurately reading the opening degree of the flat valve, and good in dust and sand prevention effect.
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 convenient to observation manual flat valve open/close states.
Background technique
At present, in Oil/gas Well well control equipment, particularly in choke manifold, manual flat valve is as core component.Manual flat valve carry out opening or closing operation time, decide the circulation status (go out stream or block) of borehole fluid.When manual flat valve keying is incomplete, the particularly completely closed situation forming flowing gap of flashboard, can be subject to the direct impact of high-voltage high-speed borehole fluid, cause flap type to tremble, valve plate ruptures even valve body thorn leakage, there is serious potential safety hazard.
The detection device of conventional rising stem type manual flat valve open/close states is the guard shield having installed band peep hole at top additional.Observed the proud exposure of guard shield inner valve stem by peep hole, roughly can judge the open/close states of flap type.
There are the following problems for this detection device: under low illumination level operating environment (as night etc.), the proud exposure being observed guard shield inner valve stem by peep hole is very difficult, can not judge the degree (such as: unlatching completely, completely closedown, half-open half are closed) that flap type opens and closes accurately simultaneously; Under harsh weather operating environment (as Gobi desert, desert etc.), can not effectively prevent sand and dust from invading, cause valve rod to rotate difficulty, valve plate opens and closes malfunctioning.
Therefore; need to carry out technological innovation to the detection device of rising stem type manual flat valve open/close states; operator and patrol officer not only can be made to carry out looking at straight, accurately detecting flap type keying degree; also the threaded stem of exposure can effectively be protected; guarantee that flap type open/close states meets the requirement of Oil/gas Well well control technique all the time, evade well control safety risk.
