Abstract
The utility model discloses a sleeving-pressing type anti-freezing anti-theft device for an oil well valve, mainly for solving the problem that the existing valve has poor anti-freezing and anti-theft effect. The device is characterized in that the lower part of an anti-theft sleeve (1) is connected with a valve hand wheel, an anti-theft pressing cap (2) is connected into the anti-theft sleeve (1) by a thread, two blind holes (4) are formed in the upper end surface of the anti-theft pressing cap (2), a block gasket (3) is arranged on the anti-theft pressing cap (2) in the anti-theft sleeve (1), and a snap spring ring (5) is arranged on the block gasket (3) and in an annular groove in the anti-theft sleeve (1). The device disclosed by the utility model is good in anti-freezing and anti-theft effect.
Description
Technical field
The utility model relates to a kind of oil field valve used, especially oil well valve casing pressure freezing-proof theft-proof device.
Background technology
In the oil extraction in oil field field, valve is well head important composition parts.Valve coordinates the drive flashboard to move up and down by nut and screw mandrel, realizes on-off action.And existing valve because reasons in structure exists the antifreeze and poor problem of anti-theft effect, affect oil recovery efficiency.
Summary of the invention
In order to solve the antifreeze and poor problem of anti-theft effect of existing valve.The utility model provides a kind of oil well valve casing pressure freezing-proof theft-proof device.This oil well valve casing pressure freezing-proof theft-proof device has antifreeze and characteristics good anti-theft effect.
The technical solution of the utility model is: this oil well valve casing pressure freezing-proof theft-proof device comprises stealingproof sleeve, anti-theft pressing cap and gear pad.Under stealingproof sleeve, be connected on valve handle, anti-theft pressing cap is threaded connection in stealingproof sleeve, and there are 2 blind holes the anti-theft pressing cap upper surface, and the gear pad is placed on the anti-theft pressing cap in stealingproof sleeve, and in the upper stealingproof sleeve of gear pad, annular groove is built-in with the jump ring circle.
The utlity model has following beneficial effect: this oil well valve casing pressure freezing-proof theft-proof device is connected on valve handle owing to adopting under stealingproof sleeve, anti-theft pressing cap is threaded connection in stealingproof sleeve, there are 2 blind holes the anti-theft pressing cap upper surface, the gear pad is placed on the anti-theft pressing cap in stealingproof sleeve, and in the upper stealingproof sleeve of gear pad, annular groove is built-in with the structure of jump ring circle.Utilize stealingproof sleeve and anti-theft pressing cap by the nut of valve and screw mandrel sealing, reach the purpose of freezing-proof theft-proof.This oil well valve casing pressure freezing-proof theft-proof device has antifreeze and characteristics good anti-theft effect thus.
the accompanying drawing explanation:
Accompanying drawing 1 is the utility model structural representation.
1-stealingproof sleeve in figure, the 2-anti-theft pressing cap, 3-keeps off pad, 4-blind hole, 5-jump ring circle.
the specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in accompanying drawing, this oil well valve casing pressure freezing-proof theft-proof device comprises stealingproof sleeve 1, anti-theft pressing cap 2 and gear pad.Stealingproof sleeve is connected on valve handle for 1 time, and anti-theft pressing cap 2 is threaded connection in stealingproof sleeve 1, and there are 2 blind holes 4 anti-theft pressing cap 2 upper surfaces, and on the anti-theft pressing cap 2 that gear pad 3 is placed in stealingproof sleeve 1, on gear pad 3, the interior annular groove of stealingproof sleeve 1 is built-in with jump ring circle 5.Stealingproof sleeve is welded on valve handle for 1 time, stealingproof sleeve 1, anti-theft pressing cap 2 and gear pad are placed in stealingproof sleeve 1, and then by the nut of valve and screw mandrel sealing, so not only guarantee that screw mandrel does not freeze, do not have the patent instrument can't open anti-theft pressing cap 2 simultaneously, the molecule that effectively avoids theft dismounting nut and screw mandrel, and then realize antitheft and antifreeze function.
Claims (1)
1. an oil well valve casing pressure freezing-proof theft-proof device, comprise stealingproof sleeve (1), anti-theft pressing cap (2) and gear pad (3), it is characterized in that: stealingproof sleeve is connected on valve handle under (1), anti-theft pressing cap (2) is threaded connection in stealingproof sleeve (1), there are 2 blind holes (4) anti-theft pressing cap (2) upper surface, the anti-theft pressing cap (2) that gear pad (3) is placed in stealingproof sleeve (1) is upper, and the upper interior annular groove of stealingproof sleeve (1) of gear pad (3) is built-in with jump ring circle (5).
