Abstract
The utility model relates to a novel anti-theft sampling valve for an oil well, which comprises a valve body, screw sleeves, bolts, a piston, a lock bolt, a lock body and a key, wherein the whole body of the novel anti-theft sampling valve is of a cylindrical boss structure, and an intersecting line is arranged at the right end of the valve body; the screw sleeves are in threaded connection with the valve body at the center of the valve body so as to locate the piston which is hard sealed in the valve body; the right end key is inserted into the lock body, and the lock bolt is inserted into the opening of the piston; the two bolts penetrates through the screw sleeve, and the lock body is fixed by the valve body; a blind center hole is arranged in the center of the piston, and a side hole which is communicated with the center hole is arranged at the left side of the piston; and a lock core in the center of the lock body is rotated by the side hole and the oil outlet hole of the piston through the key so as to drive the lock bolt, and the lock bolt drives the piston which rotates at 90 DEG in clockwise and anticlockwise directions so as to realize the communication and the closure of the side hole and the oil outlet hole. The utility model has the advantages of easiness in manufacturing, convenience in operation and accurate sampling, solves the problem that crude oil of oil wells is stolen from the sampling valve, reduces crude oil losses, effectively prevents environmental pollution, enhances the standards of oil well management, and reduces the labor intensity of workers.
Description
Technical field
The utility model relates to oilfield sampling valve for guarding against theft technology, particularly is a kind of oil well novel anti-theft sample valve.
Background technology
The oil field is in the oil well production process, and the lawless person steals crude oil through the oil well sample cock place that is everlasting, and not only causes the crude oil loss, and causes environment pollution, influences the oilfield management development, has had a strong impact on the ordinary production in oil field.Therefore, study a kind of oil well anti-theft sampling valve, i.e. sampling that can be simple, fast and easy can be played anti-theft effect again.
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 oil well novel anti-theft sample valve is provided.
Technical solutions of the utility model comprise: valve body, silk braid, bolt, plunger, dead bolt, lock body, key.The cylindrical boss structure of its oil well novel anti-theft sample valve, the valve body right-hand member is an intersection, so that with the upright conduit welding of well head, the center is threaded with valve body by silk braid, to locate with the plunger of the hard sealing of valve inner, the right-hand member key inserts lock body, and dead bolt inserts in the opening of plunger, and two bolts pass silk braid, valve body is fixed lock body.The plunger center is provided with blind centre bore, be provided with the side opening that communicates with centre bore in the plunger left side, side opening on the plunger and oil outlet drive dead bolt by the lock core at key rotation lock body center, dead bolt drives plunger, and positive hour hands half-twist realization side opening is communicated with oil outlet, realizes sampling, close the taking-up key counterclockwise, the oil well ordinary production does not have the key oil well novel anti-theft sample valve of then not opening, thereby plays antitheft effect.
The beneficial effects of the utility model are: be easy to make, easy to operate, sampling has accurately solved oil well crude oil from the stolen problem of sample cock, reduces the crude oil loss, has effectively prevented environment pollution, improves the oil well management level, alleviates working strength of workers.

The specific embodiment
Below in conjunction with accompanying drawing enforcement of the present utility model is further elaborated:
Oil well novel anti-theft sample valve is made up of valve body 1, silk braid 2, bolt 3, plunger 4, dead bolt 9, lock body 10, key 11.The cylindrical boss structure of its oil well novel anti-theft sample valve, valve body 1 right-hand member is an intersection, the center is threaded with valve body 1 by silk braid 2, to locate with the plunger 4 of valve body 1 inner hard sealing, right-hand member key 11 inserts lock body 10, dead bolt 9 inserts in the opening 8 of plunger 4, and two bolts 3 pass silk braid 2, valve body 1 is fixing with lock body 10; Plunger 4 centers are provided with blind centre bore 5, be provided with the side opening 6 that communicates with centre bore 5 in plunger 4 left sides, side opening 6 on the plunger 4 and the lock core drive dead bolt 9 of oil outlet 7 by key 11 rotation lock bodies 10 centers, dead bolt 9 drives plungers 4, just, be rotated counterclockwise 90 ° and realize being communicated with and closing of side openings 6 and oil outlet 7.
Mounting method: at first, stop oil pumper, close production gate 13 and the back pressure gate 16 of production tree 12, emptying; Secondly, the former sample cock that production tree 12 is installed slices off, and the intersection of the valve body 1 of oil well novel anti-theft sample valve 14 is welded with upright conduit 15 get final product.
