Abstract
The utility model discloses a password theft-prevention valve used in the petroleum industry, which is applied in an oil production well to replace a sampling valve to prevent law breakers from stealing crude oil and can also replace the valves that require theft-prevention or opening prevention on other occasions. The password theft-prevention valve comprises a box body and a disconnecting valve; two ends of the disconnecting valve connected with short sections are arranged inside the box body; a valve opening mechanism and a password theft-prevention mechanism are also arranged inside the box body; a guide screw of the disconnecting valve is connected with the valve opening mechanism; the password theft-prevention mechanism is matched with the valve opening mechanism. The password can be set in the password theft-prevention valve according to the requirements so as to cause each well to have different passwords, and the valve is smash-proof and prying-resistant and is hard to be stolen by the law breakers. The theft-prevention effect is good and the use is convenient.
Description
Technical field
The utility model relates to the oil production equipment of petroleum industry, and particularly a kind of cipher anti theft valve is used on the oil recovery well and substitutes existing sample cock, prevents that the lawless person from stealing crude oil, and also alternative other place needs antitheft or prevents the valve opened.
Background technique
The oil recovery well in petroleum industry field is the target that the lawless person steals crude oil always, constantly soaring along with oil price, and lawless person's stolen phenomenon is becoming increasingly rampant, and is one of main mode of lawless person's stolen from wellhead sampling valve stolen.For effectively stopping the generation of this type of phenomenon, developed many anti-theft tools, but all be to be equipped with the casing of closing, on lockset, work hard.And the casing of this type of theft-proof box has the slit, is easily pried open by the lawless person or the keyhole place is smashed.Because the well that the oil recovery worker makes an inspection tour is many, add key commonly used in the routine work, the key that causes the oil recovery worker to carry is a lot, uses also inconvenience, and cost is very high.
Summary of the invention
The purpose of this utility model provides a kind of cipher anti theft valve, prevents random Open valve, and is antitheft, improves Safety performance.
Use the present technique solution can reach above-mentioned purpose: a kind of cipher anti theft valve comprises casing and stop valve, and the stop valve two ends connect pipe nipple and are installed in the casing.Valve-lifting mechanism and cipher anti theft mechanism also are housed in the casing, and the leading screw of stop valve is connected with valve-lifting mechanism, and cipher anti theft mechanism cooperates with valve-lifting mechanism.
The utility model compared with prior art has following useful effect: the utility model is anti-to be pounded, resists and prize, and the password of every mouthful of well password valve is had nothing in common with each other, and the lawless person is difficult to implement theft.Startup disc of the present utility model is fixed on the valve leading screw, locking plate is to regulate password, and the groove of special structure is all arranged on each locking plate, have only when the structure groove of all locking plates simultaneously with the structure that starts disc at once, starting disc could rotate, and makes valve open.Prized in order to solve valve simultaneously, casing has been taked totally-enclosed mode, and valve leading screw and adjustable lever all are to fix with doubling plate, the interior square structure of adjustable lever end face, and surface of contact is seamless, and getting for sled has increased difficulty.For convenience operator's memory cipher around each root adjustable lever top on the top cover of casing, adopts digital calibration, can cooperate or comes setting code around the numbering of every mouthful of well.Only need to open the sampling cock that all manage oil wells once regulating square wrench in little.Anti-theft effect is good, and is easy to use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 be Figure 1A-A to schematic representation.
Embodiment
Below in conjunction with embodiment the utility model is done further detailed description: referring to Fig. 1 and Fig. 2, a kind of cipher anti theft valve comprises casing 1 and stop valve 4, and stop valve 4 two ends connect pipe nipple 2 and are installed in the casing 1.Valve-lifting mechanism 10 and cipher anti theft mechanism 7 also are housed in the casing 1, and the leading screw of stop valve 4 is connected with valve-lifting mechanism 10, and cipher anti theft mechanism 7 cooperates with valve-lifting mechanism 10.Casing 1 is provided with cover plate 5, base plate 3 and top cover 6, and cover plate 5 and top cover 6 are equipped with the mounting hole that cooperates with cipher anti theft mechanism 7 and valve-lifting mechanism 10.Valve-lifting mechanism 10 comprises starting bar and starts disc 9 that be fixed on the leading screw of stop valve 4, the upper-end surface of starting bar is interior square structure.Cipher anti theft mechanism 7 comprises adjustable lever and locking plate 8, and the upper-end surface of adjustable lever is interior square structure, lower end fixed stop sheet 8.Start concavo-convex, the mutual correspondence of shape of disc 9 and locking plate 8.If start disc 9 is circular, design of curved slots on the locking plate 8 then, as shown in Figure 2.If starting disc 9 is polygonals, then design the breach corresponding on the locking plate 8 with polygonal.When stop valve 4 is in the closed position, locking plate 8 is installed in the top that starts disc 9, stop that starting disc 9 moves up, and prevents to open stop valve 4.For ease of the setting of complicated password, in this cipher anti theft valve, be provided with a cover cipher anti theft mechanism 7 at least, attached Fig. 1 and 2 represents to be provided with two cover cipher anti theft mechanisms 7.As shown in Figure 2, when the curve bath of locking plate 8 with start disc 9 involutory after, could rotate the leading screw that starting bar drive stop valve 4 with interior square head wrench and rotate, open stop valve 4, emit crude oil.
During concrete the use, pipe nipple 2 one ends are connected with the crude oil export pipeline, the other end is a fuel outlet.When the oil recovery workman need draw oil sample, press password rotational password burglar-proof mechanism 7 with interior side's wrench, make the structure on the locking plate 8 involutory with the structure that starts disc 9, the starting bar of promptly available interior square wrench rotating valve opening mechanism 10 is opened stop valve 4.Sampling finishes, and closes stop valve 4 with interior side's wrench, and square wrench rotational password burglar-proof mechanism 7 in using again makes the structure on the locking plate 8 staggered with the structure that starts disc 9, makes startup disc 9 be hampered and can not upper and lowerly move, and prevents that the lawless person from stealing crude oil.When use in other place, the export pipeline of pipe nipple 2 with other liquid or gas is connected, using method is identical.
