Abstract
The utility model relates to a well mouth anti-freeze and anti-theft sampling device which mainly solves the problem of poor anti-freeze and anti-theft effect of the traditional sampling valve. The well mouth anti-freeze and anti-theft sampling device is characterized in that the outer tip of a valve rod (3) is a heptahedron; a valve hole (5) connected with a main liquid channel (2) and an evacuation hole (4) is transversely arranged on a valve body (1), a small valve cage (6) is arranged in the valve hole (5) and radially provided with a through hole, a compression spring (7) is arranged in the small valve cage (6), the right end of the compression spring (7) is provided with an evacuation valve rod (8), the left tip of the evacuation valve rod (8) is in the conical shape, the right tip of the evacuation valve rod (8) is a heptahedron, the evacuation valve rod (8) is connected with a valve cap (9) by screw threads, and the valve cap (9) is connected with the valve body (1) by screw threads. The well mouth anti-freeze and anti-theft sampling device has the characteristics of good anti-freeze and anti-theft effect.
Description
Technical field:
The utility model relates to oil recovery field, oil field well head used valve, especially well head freezing-proof theft-proof sampler.
Background technology:
In oil recovery field, oil field, in order to obtain technical data, sample valve is installed on well head, take well liquid sample by sample valve.And existing sample valve makes thief steal crude oil by sample valve because reasons in structure exists problem antifreeze, the anti-theft effect difference, causes damage for country and enterprise.Simultaneously, sampling back at the easy freezing sample valve of cold district, causes producing well or water injection well to stop production owing to has raffinate in the valve, influences producing well or water injection well normally moves.
The utility model content:
In order to solve the problem of existing sample valve freezing-proof theft-proof weak effect.The utility model provides a kind of well head freezing-proof theft-proof sampler.This well head freezing-proof theft-proof sampler has the freezing-proof theft-proof good effectiveness.
The technical solution of the utility model is: this well head freezing-proof theft-proof sampler comprises the valve rod of valve body, channel for main liquid, feed liquor valve and liquid valve.The valve rod external end head is a heptahedron; Laterally have the valve opening that links to each other with relieving device with channel for main liquid on the valve body, valve opening is built-in with little valve cage, little valve cage radially has through hole, little valve cage is built-in with stage clip, the stage clip right-hand member has the emptying valve rod, and emptying valve rod left end head is taper, and emptying valve rod right-hand member head is a heptahedron, the emptying valve rod is connected with bonnet by screw thread, and bonnet is connected with valve body by screw thread.
The utlity model has following beneficial effect: this well head freezing-proof theft-proof sampler is at first because the external end head of the valve rod of feed liquor valve, liquid valve and emptying valve rod is adopted as the simple structure of heptahedron.Utilize special tool to cooperate switch, in that do not have under the situation of special tool can't switch, and then realize antitheft destination.Again because employing laterally has the valve opening that links to each other with relieving device with channel for main liquid on valve body, valve opening is built-in with little valve cage, little valve cage radially has through hole, little valve cage is built-in with stage clip, and the stage clip right-hand member has the emptying valve rod, and emptying valve rod left end head is taper, emptying valve rod right-hand member head is a heptahedron, the emptying valve rod is connected with bonnet by screw thread, and the structure that bonnet is connected with valve body by screw thread is formed atmospheric valve.Put raffinate in the valve body only by atmospheric valve the sampling back, thereby prevent that effectively the freezing phenomenon of sample valve from producing, and reaches antifreeze purpose.This well head freezing-proof theft-proof sampler has the freezing-proof theft-proof good effectiveness thus.
Description of drawings:
Accompanying drawing 2 is Fig. 1 views.
1-valve body among the figure, 2-channel for main liquid, 3-valve rod, 4-relieving device, 5-valve opening, the little valve cage of 6-, 7-stage clip, 8-emptying valve rod, 9-bonnet.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in the figure, this well head freezing-proof theft-proof sampler comprises the valve rod 3 of valve body 1, channel for main liquid 2, feed liquor valve and liquid valve.Valve rod 3 external end heads are seven irregular bodies, and valve rod 3 is furnished with special tool, have only with special tool and just can open feed liquor valve and liquid valve, thereby reach antitheft purpose.Laterally have the valve opening 5 that links to each other with relieving device 4 with channel for main liquid 2 on the valve body 1, valve opening 5 is built-in with little valve cage 6, and little valve cage 6 radially has through hole, and little valve cage 6 is built-in with stage clip 7, pushes down little valve cage 6 by stage clip 7, prevents that little valve cage 6 from moving.Stage clip 7 right-hand members have emptying valve rod 8, emptying valve rod 8 left end heads are taper, cooperate the realization hermetically closing with little valve cage 6 bottom outlets by emptying valve rod 8 conical heads, emptying valve rod 8 right-hand member heads are heptahedron, emptying valve rod 8 is furnished with special tool, have only with special tool and could open emptying valve rod 8, thereby reach antitheft purpose, emptying valve rod 8 is connected with bonnet 9 by screw thread, screw thread between emptying valve rod 8 and the bonnet 9 is realized the unlatching of emptying valve rod 8 or is closed, bonnet 9 is connected with valve body 1 by screw thread, realizes being tightly connected of emptying valve rod 8 and valve body 1 by bonnet 9.
This well head freezing-proof theft-proof sampler has been obtained remarkable result by The field.
