Abstract

A theft-proof device for valve mainly solves the poor theft-proof effect of the prior valve. The utility model is characterized in that: the inner step of a body case (4) is provided with an end cover (8) with a power socket (7), an inner circular disc (2)and an upper flange (9)in turn via a bolt (10). A screw (11) is arranged between an inner inlay (6) and the upper flange (9). A partition board (12) set in the inner inlay (6) is provided with a nut coupling (5) that has a step hole (1) in the center along axial direction. Lock pins (3) connected with a magnet are positioned in the holes of the nut coupling (5) and the upper flange (9. The theft-proof device for valve has not only good theft-proof effect but also convenient installation.

Description

The valve alarm

Technical field:

The utility model relates to oil well mouth field used a kind of alarm, especially valve alarm.

Background technique:

The oil well mouth all links to each other with pipeline by valve at present, and valve does not have desirable anti-thefting facility, can open arbitrarily under unattended situation, causes crude oil stolen, produces to the oil field and causes very big economic loss.And used valve exists stolen phenomenon to some extent in fields such as chemical industry, weavings, does not also have feasible measure to solve; And also exist to some extent by the pirate of the open phenomenon at used valves of equipment such as rock gas, coal gas, water and heating, more existing anti-theft devices generally adopt mechanical code lock to add the special key composition, in case can not in time open or close when having urgency to take place, so just can not pin valve in the control flow rate arbitrarily, inconvenient operation, using scope is little.

The model utility content:

In order to overcome the deficiency of existing valve anti-theft effect difference, the utility model provides a kind of valve alarm, and this valve alarm is good anti-theft effect not only, and installs easily.

The technical solution of the utility model is: have the housing of magnet to link to each other with interior inlay on the disk in this valve alarm comprises, on the housing inner step by bolt be fixed with successively the end cap of charged supply socket, interior disk and on connect dish, interior inlay and on connect screw arranged between dish, be equipped with the nut land of band step hole axially placed in the middle on the dividing plate in the interior inlay, the hole that connects dish on the nut land reaches is built-in with the lock pin that links to each other with magnet.

The beneficial effect that the utlity model has is: this valve alarm is owing to adopted such scheme, and the sub-pirate of the open valve that can avoid theft is effectively stolen crude oil, and then avoids crude oil stolen, guarantees oilfield safety production; The end cap of this alarm, interior disk reach to connect to coil by bolt and fix successively simultaneously, interior inlay and on connect screw arranged between dish, under the situation that does not change valve, this valve alarm can be installed on the valve like this, have and install simply, do not destroy existing facility, easy to operate, applicability is strong, cost hangs down characteristics, suitable applying.

Description of drawings:

Accompanying drawing 1 is a structure sectional view of the present utility model.

1-hole among the figure, disk in the 2-, the 3-lock pin, the 4-housing, inlay in the 5-nut land, 6-, the 7-power socket, the 8-end cap connects dish on the 9-, 10-bolt, 11-screw, 12-dividing plate.

Embodiment:

Below in conjunction with accompanying drawing will the utility model is described in further detail:

By shown in Figure 1, in comprising, this valve alarm have the housing 4 of magnet to link to each other on the disk 2 with interior inlay 6, on housing 4 inner steps by bolt 10 be fixed with successively the end cap 8 of charged supply socket 7, interior disk 2 and on connect dish 9, interior inlay 6 and on connect the dish 9 screw 11 is arranged, be equipped with the nut land 5 of band step hole 1 axially placed in the middle on the dividing plate 12 in the interior inlay 6, nut land 5 reaches the hole that connects dish 9 and is built-in with the lock pin 3 that links to each other with magnet.

During actual the use, earlier with interior inlay 6 and valve welding, on the dividing plate 12 in then nut land 5 being placed in the inlay 6, and the step hole 1 of nut land 5 links to each other with the valve rod of valve, with end cap 8, interior disk 2 and on connect dish 9 and be fixed on successively in the housing 4 by bolt 10, housing 4 links to each other with interior inlay 6 by screw thread, on being connected in screw 11, auxiliary hole in reaching by end cap 8 on the disk 2 connects in the tapped hole of dish 9 and interior inlay 6, then that auxiliary hole electricity consumption sealing is stifled, install, at this moment power supply can be linked to each other with power socket, by remote controller control lock pin 3, when energising back lock pin 3 is pulled out the hole of nut land 5 by magnet, at this moment nut land 5 can drive the valve rod rotation and makes valve opening or close.Use more safe and efficiently, when mounted, original valve is not produced and destroy, do not influence the anti-collapsing force that the ordinary production alarm self has extra-heavy, protected the normal operation of production and lifestyle device.Easy to operate, avoided crude oil stolen, guarantee oilfield safety production, suit in using valve field, to apply.

Claims

1, a kind of valve alarm, comprise and have the housing of magnet (4) to link to each other on the interior disk (2) with interior inlay (6), it is characterized in that: on housing (4) inner step by bolt (10) be fixed with successively the end cap (8) of charged supply socket (7), interior disk (2) and on connect dish (9), interior inlay (6) and on connect screw (11) arranged between dish (9), be equipped with the axially nut land (5) of band step hole placed in the middle (1) on the dividing plate (12) in the interior inlay (6), the hole that connects dish (9) on nut land (5) reaches is built-in with the lock pin (3) that links to each other with magnet.
