Abstract
The utility model provides a multifunctional anti-theft device for crude oil, the anti-theft device mainly solves problem of poor anti-theft effect of a valve on a current wellhead. The multifunctional anti-theft device for crude oil is characterized in that: a protective cover (2) is welded at the external of a valve big pressing cap (3), cement (8) is filled between the protective cover (2) and the valve big pressing cap (3), the internal of the protective cover (2) is transversely fixedly provided with a lock pin (4), the upper end surface of the protective cover (2) is provided with digital scale lines, a cipher lock core (1) is placed in the protective cover (2), the external of the cipher lock core (1) is provided with more than two ways of annular grooves (5), a radial boss between the annular grooves is provided with more than two openings (6), one side of the openings (6) is provided with an axial boss (7) sealing the annular grooves (5), and the lock pin (4) is disposed in the annular grooves (5). The multifunctional anti-theft device for crude oil is characterized by good anti-theft effect and simple structure.
Description
Technical field:
The utility model relates to oil recovery field, oil field head valve used anti-theft device, especially multifunctional crude oil anti-theft device.
Background technology:
In oil recovery field, oil field, oil field shaft mouth is equipped with well head, is connected with many valves on well head, controls various pipelines by valve.Because well head is in the open air, manageability not, the valve on the well head does not have effective anti-theft device, and thief is stolen crude oil by Open valve, causes the state-owned resource loss, gives to produce and also brings potential safety hazard.
The utility model content:
In order to solve the problem of valve anti-theft effect difference on the existing well head.The utility model provides a kind of multifunctional crude oil anti-theft device.This multifunctional crude oil anti-theft device has good anti-theft effect, characteristic of simple structure.
The technical solution of the utility model is: this multifunctional crude oil anti-theft device comprises protective sleeve and cipher lock.Protective sleeve is welded on outside the big pressure cap of valve; be filled with cement between the big pressure cap of protective sleeve and valve; crosswise fixed has lock pin in the protective sleeve; there is the digital calibration line protective sleeve upper surface, and cipher lock places in the protective sleeve, and cipher lock has the above annular groove in 2 roads outward; 2 above gap are arranged on the radially boss between the annular groove; gap one side has the axial boss of closed ring groove, and lock pin places in the annular groove, jug on the cipher lock.
Cipher lock in the such scheme has 4 road annular grooves outward.
The utlity model has following beneficial effect: this multifunctional crude oil anti-theft device is at first owing to adopt at the big pressure cap external welding of valve protective sleeve; be filled with cement between the big pressure cap of protective sleeve and valve; crosswise fixed has lock pin in the protective sleeve; lock pin places in the annular groove; cipher lock places in the protective sleeve; cipher lock has the above annular groove in 2 roads outward, and 2 above gap are arranged on the radially boss between the annular groove, and gap one side has the structure of the axial boss of closed ring groove.Utilize lock pin fixing in the protective sleeve to be stuck in the annular groove; and can freely rotate; and do not have the password rotation not come out, and also just can't in protective sleeve, take out cipher lock, can not get cipher lock and also just can't open valve by rotary valve rod; play antitheft effect; thereby the raising anti-theft effect, thereby reaching antitheft purpose, the molecule that effectively avoids theft theft crude oil phenomenon produces; and simple in structure, have the characteristics of application.This multifunctional crude oil anti-theft device has good anti-theft effect, characteristic of simple structure thus.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
1-cipher lock among the figure, 2-protective sleeve, the big pressure cap of 3-valve, 4-lock pin, 5-annular groove, 6-gap, 7-axial boss, 8-cement, 9-handle.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
Shown in accompanying drawing, this multifunctional crude oil anti-theft device comprises protective sleeve 2 and cipher lock 1.Protective sleeve 2 is welded on outside the big pressure cap 3 of valve, is filled with cement 8 between the big pressure cap 3 of protective sleeve 2 and valve, utilizes cement 8 further to protect, and the molecule that avoids theft cuts protective sleeve 2 with gas cutting.Crosswise fixed has lock pin 4 in the protective sleeve 2, and there is the digital calibration line protective sleeve 2 upper surfaces, and cipher lock 1 places in the protective sleeve 2, utilizes cipher lock 1 to hide password protection sheath 2 inner valve stem.Outside the sign indicating number lock core 14 road annular grooves 5 are arranged, on the radially boss between the annular groove 5 gap axial more than 26 is arranged, gap 6 one sides have the axial boss 7 of closed ring groove 5, lock pin 4 places in the annular groove 5, utilize the gap 6 on the boss between annular groove 5 and the annular groove 5, form the password of different directions Rotary puzzle lock core 1.By protective sleeve 2 and cipher lock 1 that the valve rod of valve is hidden, do not have under the situation of password be can't changeover valve valve rod.Jug 9 on the cipher lock 1.
During actual the use, because this multifunctional crude oil anti-theft device is welded on outside the big pressure cap 3 of head valve.When opening or closing valve; need in protective sleeve 2, take out cipher lock 1 operating process; by the 9 positive and negative rotation cipher locks 1 of the handle on the Rotary puzzle lock core 1; upwards carry cipher lock 1 when making cipher lock 1 directrix have the digital calibration line to aim at protective sleeve 2 upper surfaces; lock pin 4 in the protective sleeve 2 lays out by gap axial on the annular groove 56; cipher lock 1 takes out in protective sleeve 2 the most at last, can use instrument rotary valve rod Open valve.Reverse operating is toward the protective sleeve 2 interior operating process that cipher lock 1 is installed.
Claims (2)
1. multifunctional crude oil anti-theft device; comprise protective sleeve (2) and cipher lock (1); it is characterized in that: protective sleeve (2) is welded on outside the big pressure cap of valve (3); be filled with cement (8) between protective sleeve (2) and the big pressure cap of valve (3); the interior crosswise fixed of protective sleeve (2) has lock pin (4); there is the digital calibration line protective sleeve (2) upper surface; cipher lock (1) places in the protective sleeve (2); the above annular grooves in 2 roads (5) are arranged outside the cipher lock (1); 2 above gap (6) are arranged on the radially boss between the annular groove (5); gap (6) one sides have the axial boss (7) of closed ring groove (5); lock pin (4) places in the annular groove (5), and cipher lock (1) is gone up jug (9).
