Abstract
The utility model relates to an anti-freezing and anti-burglary crude oil sampling valve, which is installed inside an oil return pipe of an oil well and is semi-built-in. The entire valve core is immersed in flowing crude oil, crude oil in the valve has the same temperature with that in the pipe and is in flowing state, and an exposure portion is used to be welded with the oil pipe and connected with a portable oil taking tool. The valve body and the valve core utilize conical seal, the upper portion of the valve core utilizes an annular groove and an inverted T-shaped circular hole to guide liquid, and the lower portion of the valve core uses a straight groove to guide liquid. The anti-freezing and anti-burglary crude oil sampling valve has the advantages of simple structure, convenient installation and usage, good anti-burglary function and unique anti-freezing function.
Description
Technical field
The utility model discloses a kind of oil field head valve, particularly a kind of antifreeze, antitheft crude oil sampling valve that is exclusively used in oil well.
Technical background
In oilfield process, from the valve of well head extraction oil sample, generally be on oil return pipe, to open a mouth, the short tube of the one one headband screw thread of burn-oning is installed a valve in the outer end of pipe then.When drawing oil sample, open valve and get final product, more convenient.Thisly get oily mode, exist two weak points.The one, non-anti-theft, the stolen incident of crude oil occurs repeatedly, and quite a few is stolen from this valve, and for the antitheft oil field that has adds an antitheft cover and pins getting on the fuel tap door, antitheft so cumbersome, effect is also undesirable.The 2nd, not antifreeze, because the crude oil at short tube and valve place in process of production, is to remain static, do not flow.After weather is reduced to a certain degree than chill temperature, just the crude oil in the pipe can be thick with fixed attention,, also may freeze if crude oil water containing is more, the valve bursting by freezing when drawing oil sample, is put to come out when serious, have only by heating make crude oil thinning or thaw after, could extract oil sample.To extract the process of oil sample longer for mode in this, relatively wastes time and energy, and get angry at well head, has certain danger.
Summary of the invention
The purpose of this utility model provides a kind of antifreeze, antitheft crude oil sampling valve, the inside that is installed in the oil well oil return pipe of this valve is partly built-in, and whole spool part is immersed in the mobile crude oil entirely, the crude oil and the crude oil in the pipe of valve are same temperature, and are in flow regime.
The purpose of this utility model is achieved in that this valve mainly is made up of valve body, spool, spring and spring base.Its valve body and spool adopt the sealing of vertebra face, and spool top adopts the annular groove and the T-shaped circular hole that falls that liquid is carried out water conservancy diversion, and straight trough water conservancy diversion liquid is then adopted in the spool bottom.Its operating principle, under the effect of spring, valve is a normally closed type, when the effect bottom spool at special tool moves down, spring is compressed.The interior liquid of guide groove this moment flows out to cannelure to the circular hole of falling the T-shaped by the vertebra face, realizes drawing oil sample purpose.When sampling finishes, take off the sampling special tool, spool moves automatically under the effect of spring and closes.
The utility model was compared with the former valve that draws oil sample, have simple in structure, low cost of manufacture, characteristics easy for installation, simple to operate.In the use, do not have the phenomenon generation that crude oil exosmoses, sprays, spatters outward outward, the feature of environmental protection is good.During operation, operating personnel's labour intensity is low, and is time saving and energy saving.
Description of drawings
Fig. 1 is the utility model structural representation.
1 is valve body among the figure (1), and 2 is that insulation ring-like space, 3 is that adapter sleeve, 4 and 6 is that spool, 5 is that spring, 7 is spring base.
The specific embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing: this valve is installed in the inside of oil well oil return pipe, be partly built-in, whole spool part is immersed in the mobile crude oil entirely, and its exposed parts is to be used for and oil pipe welding and the part that is connected portable oil taking tool, and length is about 3 centimetres.This valve mainly is made up of valve body (1), spool (4) and spool (6), spring (5) and spring base (7), and its valve body (1) adopts the sealing of vertebra face with spool (4) and spool (6).Spool (4) top adopts the annular groove and the T-shaped circular hole that falls that liquid is carried out water conservancy diversion, and straight trough water conservancy diversion liquid is then adopted in spool (4) bottom.Under the effect of spring (5), valve is normal valve formula, and when the effect bottom spool (4) at special tool moves down, spring (5) is compressed.The interior liquid of guide groove this moment flows out to cannelure to the circular hole of falling the T-shaped by the vertebra face, realizes drawing oil sample purpose.When sampling finishes, take off the sampling special tool, spool (4) moves automatically under the effect of spring (5) and closes.
The utility model was compared with the former valve that draws oil sample, and had simple in structurely, manufactured The characteristics that this is low, easy for installation, simple to operate. In the use procedure, do not have crude oil exosmose, Outer spray, the phenomenon of spattering outward take place, and the feature of environmental protection is good. During operation, operating personnel's labour intensity is low, Time saving and energy saving. The utility model is applicable to various producing wells, has good anti-theft feature with unique Antifreeze function, the vast north cold area of particularly suitable and China is for the cold district oil well is got Oil sample provides convenience, has great popularizing value.
Claims (2)
1. antifreeze, antitheft crude oil sampling valve, by valve body (1), be incubated ring-like space (2), adapter sleeve (3), spool (4), spring (5), spool (6), spring base (7) and formed, it is characterized in that valve body (1) and spool (4) and spool (6) adopt the sealing of vertebra face, the annular groove and the T-shaped circular hole that falls are adopted in spool (4) top, and straight trough is adopted in spool (4) bottom.
2. antifreeze, antitheft crude oil sampling valve according to claim 1 is characterized in that this valve is installed in the inside of oil well oil return pipe, is partly built-in.
