Abstract
The invention discloses a separated hollow thimble sampling frost valve with a one-way valve, and belongs to a sampling tool for still sampling crude oil in an oil field in the cold winter. The separated hollow thimble sampling frost valve mainly comprises a hollow needle type thimble 5 provided with liquid passing holes in the front and back sides, wherein a liquid flowing passage of liquid consists of a cavity, formed by a gap of a steel ball return spring, a gap for downward moving and retreating a steel ball, the front liquid passing hole of the thimble 5, a hollow pipe of the thimble 5, the back liquid passing hole of the thimble 5, a return spring 9 and a spring base 10, and a sampling pipe 11; a knob hand wheel 12 clockwise rotates to open the liquid flowing passage to access the sampling working condition; and otherwise, the knob hand wheel 12 anticlockwise rotates to close the liquid flowing passage to retreat from the sampling working condition.
Description
Technical field the present invention is the hollow thimble sampling anti-freeze valve of a kind of separate type with one way valve, belongs to the improvement field that winter still can guarantee the sampling instrument that carry out crude oil sampling work of oil field in severe cold.
Background technology, in oil extraction in oil field is produced, needs often to take the oil sample of every mouthful of oil well, is commonly called as sampling; But in the winter of severe cold, because the oil sample of High water cut often freezes at sample cock place, this work can not normally be carried out.
Summary of the invention is for the current frozen problem that winter, oil well sampling existed, present invention employs the hollow thimble sampling anti-freeze valve of a kind of separate type with one way valve (being called for short: sample valve), it is characterized in that: sample valve of the present invention is separable into two parts, first standing part, by fixed housing 1, one way valve group 2, attachment cap 3, leakproof plug 4, tie flexible cord 13, connect sealing ring 14, one way valve sealing ring 15 and form, be fixed in sampled container conduit 16 at ordinary times; It two is movable parts, its core is the hollow needle form thimble 5 that front and back all have liquid pass hole, mix round thimble 5 movable part that sampling valve body 6, thimble overcoat 7, thimble sealing 8, back-moving spring 9, spring base 10, probe tube 11 and knob handwheel 12 constitute sample valve of the present invention again, can be held it by sampling personnel at ordinary times and repeatedly sample in many places; Because the liquid in sampled container conduit 16 is can not freezing of flowing, therefore, the liquid around one way valve group 2 also can not freeze; During sampling, the thimble 5 in the movable part of sample valve of the present invention backs down the steel ball in one way valve group 2, and sampled liquid just by the front and back perforate on thimble 5, can flow to probe tube 11, complete sampling work.Because sample valve of the present invention is separated into two parts, so when carrying out sampling work, after needing to be assembled, just sampling work can be carried out.Before sampling, first unclamp and unload leakproof plug 4, then the movable part of sample valve is arranged on fixed housing 1.During sampling, turn knobs handwheel 12 promotes spring base 10 downwards, and compression reseting spring 9, forces thimble 5 also to move downward, finally back down the steel ball in one way valve group 2, open the flow channel of sampled liquid; After sampling liquid reaches some, original position return by derotation knob handwheel 12, steel ball in one way valve group 2 and thimble 5 also return original position under the acting in conjunction of fluid pressure and back-moving spring 9, close one way valve group 2, enclose the flow channel of sampled liquid.After whole sampleman completes, turn attachment cap 3 unloads the movable part of sample valve, then is arranged on fixed housing 1 by leakproof plug 4.
Below in conjunction with Figure of description and embodiment, the present invention will be further described.
Appended drawings 1 is the structural principle schematic diagram of the hollow thimble sampling anti-freeze valve of the separate type with one way valve of the present invention, the standing part of sample valve is welded in sampled container conduit 16, the movable part of sample valve has been installed on standing part, is in sampling duty; Wherein knob handwheel 12 is contained in topmost, and the steel ball in it and back-moving spring 9, spring base 10 and thimble 5 and one way valve group 2 constitutes one group of moving parts moving up and down, by their movement, and steel ball able to turn on or off; Leakproof plug 4 is tied flexible cord 13 bolt on attachment cap 3, with anti-lost.
The detailed description of the invention separate type with one way valve of the present invention hollow thimble sampling anti-freeze valve has a flow channel able to turn on or off, below in conjunction with embodiment, is further described this point.In sample valve of the present invention, the gap of steel ball back-moving spring, steel ball move down the flow channel that cavity volume that the space, the front liquid pass hole of thimble 5, the hollow tube of thimble 5, the rear liquid pass hole of thimble 5 and back-moving spring 9 and the spring base 10 that exit formed and probe tube 11 constitute liquid; By mobile thimble 5 just steel ball able to turn on or off, realize conducting or close flow channel; Thimble 5 is connected on spring base 10, so, as long as move spring base 10 just achieve keying flow channel.The effect of back-moving spring 9 abuts against on knob handwheel 12 by spring base 10, therefore, as long as turn knobs handwheel 12 just can open flow channel clockwise, enters sampling operating mode; Otherwise counterclockwise turn knobs handwheel 12 just can cut out flow channel, exits sampling operating mode.After sampleman completes, be rotated counterclockwise attachment cap 3, unload the movable part of sample valve, set up leakproof plug 4 simultaneously, screw attachment cap 3, just can guarantee this sample point No leakage.
