Abstract
The utility model relates to a thief protection tool of oil field, more particularly a valve free of hand wheel. The technical project of the utility model is that: the valve comprises a valve body, a valve support fixed on the valve body, a screwed rod nut with an outer profile of polygon and screwed thread on the inner surface, a screwed rod connected with the valve body via the screwed rod nut, and a transverse barrier plate connected with the bottom of the screwed rod nut and arranged in the valve support. Two holes are formed on two sides of the valve support at position close to the bottom of the screwed rod nut, and the screwed rod is inserted through the hole to support the screwed rod nut. By forming screwed connection of the screwed rod and a special hand wheel, the opening and closing of the valve can be realized by rotating the hand wheel. The hand wheel can be taken away when being not in use, thus thief and damage caused by other ways are avoided and loss of application pin is avoided.
Description
One, technical field:
The utility model relates to a kind of anti-theft tool of oil field, particularly relates to a kind of no handwheel valve.
Two, background technique:
The valve that uses in the open-air production in oil field generally is made up of handwheel, feed screw nut, key, screw mandrel, the problem of its existence is: the one, often occur valve handle destroyed, lose or disorderly opened the phenomenon of disorderly closing by the lawless person, brought a lot of problems for ordinary production and emergency processing, outer gas transmission once just occurred and be connected valve with domestic gas and be opened, brought about great losses; The 2nd, the key that connects between what feed screw nut of handwheel often comes off, and lowered in field environment is difficult to find.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of no handwheel valve that has anti-theft feature and do not need key is provided.
Its technological scheme is: comprise valve body, valve body support, feed screw nut, screw mandrel, described valve body support is fixed on the valve body, screw mandrel connects valve body by the feed screw nut, described feed screw nut's outer ring is made as many prismatics, and be provided with outside thread, inner ring is provided with internal thread, and its bottom connects transverse baffle, and described transverse baffle is located in the valve body support; Described valve body support is near two holes of processing, both sides of feed screw nut's bottom position, and the precession screw rod is held the feed screw nut.
Described feed screw nut outer ring is made as quadrilateral.
The beneficial effects of the utility model are: special handwheel precession feed screw nut can be rotated the open and close that handwheel can be realized valve; Not the time spent, can directly handwheel be unloaded and take away, prevent the destruction of stolen or other modes, also avoid the situation of using pin often to lose.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Five, embodiment:
In conjunction with the accompanying drawings, the utility model will be further described: its technological scheme is: comprise valve body 4, valve body support 7, feed screw nut 6, screw mandrel 5, described valve body support 7 is fixed on the valve body 4, screw mandrel 5 connects valve body by feed screw nut 6, and described feed screw nut's 6 outer ring is made as many prismatics, and inner ring is provided with internal thread, connect screw mandrel 5 by internal thread, its bottom connects transverse baffle 8, and described transverse baffle 8 is located in the valve body support 7; Described valve body support 7 is near two holes of processing, both sides of feed screw nut's bottom positions, and precession screw rod 1 holds feed screw nut 6, is used for preventing that the feed screw nut from falling to entering the valve body internal stent.Described feed screw nut 6 outer rings can be made as quadrilateral, promptly have four planes 3, its outer ring also is provided with outside thread 2, handwheel is special, promptly also is tetragonal hole, and can be with internal thread, can enter by the outside thread rotation like this, move up and down thereby drive screw mandrel 5, and open or throttle down.
During use, special handwheel precession feed screw nut can be rotated the open and close that handwheel can be realized valve; Also can not need handwheel, directly adopt spanner rotary screw rod nut to realize; Not the time spent, can directly handwheel be unloaded and take away, prevent stolen or destruction.
Claims (2)
