Description

The valve alarm

The utility model relates to valve anti-theft technique in the open-air production in oil field, particularly is a kind of valve alarm.

At present, in the oil field development production process, crude oil and valve components are often stolen, often produce and cause heavy losses to the oil field, for this reason, oil field worker and engineers and technicians have carried out a large amount of anti-theft technique research work, have taked various anti-theft measure respectively, obtained certain effect, for example valve for guarding against theft because it costs an arm and a leg, is to influence ordinary production with the existing valve one of its replacement, the 2nd, cause unnecessary waste, thereby prior art can not satisfy the field produces needs.

The purpose of this utility model is exactly a kind of valve alarm that designs at above-mentioned deficiency.

Above-mentioned purpose is realized by following technical proposals: this valve alarm, it is characterized in that by shell, loam cake, pressing plate, locking plate, spacer ring, lock shaft is formed, shell 4 is a drum shape, shell 4 is welded as a whole with base plate 9, lining 5 forms annular space H with shell 4, offer 4 or 5 spacer rings 7 between successively in the annular space H, 3-4 locking plate 8, spacing with pressing plate 6, pressing plate 6 is provided with internal thread and lining 5 set outside threads and connects as one, loam cake 2 is provided with central through bore A, be provided with 2 symmetrical handles 1 above the loam cake, be provided with 2 or 3 lock shafts 3 below, the bottom of lock shaft 3 is provided with the groove G corresponding with the number of locking plate 8, lock shaft 3 is by the hole B on the pressing plate 6, penetrate the semicircle orifice E on the locking plate 8, enter the hole I on the base plate 9;

Shell 4 in the above-mentioned valve alarm, be provided with in the middle and lower part one up and down two ends be the rectangular through holes C of semicircle, on the C hole, can see the number of locking plate 8.

Locking plate 8 in the above-mentioned valve alarm, for having the annulus of certain thickness and width, the center is provided with through hole F, the semicircle orifice E that two symmetries are arranged on the internal diameter edge, have several rectangular slots D on the outer annulus edge, indicate Arabic numerals or English alphabet at projection, the setting of staggering of the number on the periphery of locking plate 8 and identical number on the adjacent locking plate 8 is not at same position.

Advantage of the present utility model is that it is simple in structure, make easily, be applicable to all kinds of valves, install do not stop production, easy to use, can prevent effectively that the stolen and valve components of crude oil from losing, this guarantees the oil field sustainable and stable development for safeguarding oilfield safety production, have great social benefit and economic benefit, be worth of widely use.

In order to disclose the technical solution of the utility model in detail, be further elaborated by embodiment below in conjunction with Figure of description:

The installation of valve alarm, lock, open method:

At first base plate 9 levels are put into shell 4 inside, weld together with shell 4 bottoms, lining 5 is vertically put in the shell 4, bottom and base plate screwed connection, spacer ring 7 and the locking plate 8 that is provided with center hole F are put into shell 4 and the annular space H that lining 5 forms at interval, require to put 3-4 locking plate and supporting spacer ring according to theftproof performance.Pressing plate 6 is put into shell 4, be threaded with lining 5 tops, again will below be welded with 2 or 3 lock shafts and above be welded with 2 handles the loam cake that is provided with center hole A 2 put in the shell 4, lock shaft 3 passes the B hole of pressing plate 6 and the semicircle orifice E on the locking plate 8, penetrate the I hole on the base plate again, make the groove G of lock shaft 3 corresponding, the handwheel of valve 10 is laid down with the rectangular slot D of locking plate 8, put alarm, the base plate of alarm is welded with valve body.

During switch valve, Arabic numerals inside at first stirring on the locking plate by the C hole of shell 4, oneself setting appears in three locking plates simultaneously when digital, illustrate that promptly alarm is opened, portable handle 1 is extracted the loam cake of alarm out from the valve leading screw, the keyway that opens and closes nut 11 is inserted in the key of original screw set, and then the screw cap hole 13 with the sleeve 14 of special opening valve is inserted in the keying nut 11, opens valve.If press the above during throttle down, at first valve is shut with special-purpose long sleeve spanner, the loam cake of alarm is inserted in the valve leading screw, put into shell, the number that changes on the locking plate can be with on the valve, because of valve in the position of opening or closing, leading screw is covered, is not known that by alarm the people of password can't open and close all the time, has prevented that the bad person from destroying field produces or oil product is stolen.Play a role for guaranteeing oilfield safety production.
