Abstract
The utility model relates to a ferromagnetic safety valve, which mainly solves the problem of the poor anti-burglary effect of the prior valve. The utility model is characterized in that: an anti-burglary sleeve (4) is arranged outside a nut (1) on a valve (2); a magnetic steel (5) is arranged inside the radial hole of the nut (1) and a ring-shaped groove of a valve cover anti-burglary sleeve (4); a valve rod anti-burglary cap (7) in the shape of a hexagon is covered outside the upper end of a valve rod (3); a eccentric orifice at the upper end of the valve rod (3) is provided with a torque transmission magnetic steel (6); a dead hole (8) is arranged inside the upper end of valve rod anti-burglary cap (7) corresponding to the torque transmission magnetic steel (6); a limit pin (9) is arranged inside the radial hole of the valve rod (3) and the valve rod anti-burglary cap (7). The utility model is characterized in good anti-burglary effect and simple structure.
Description
Technical field:
The utility model relates to the used valve of oil recovery field, oil field well head, especially strong magnetic valve for guarding against theft.
Background technique:
According to the oil recovery manufacturing technique requirent, oil field shaft mouth is equipped with production tree, is connected with various valves on production tree and petroleum pipeline, controls various pipelines by valve.Because valve disperses to install, floor space is big, and manageability does not have effective anti-theft device again, and thief is stolen crude oil by opening valve, causes the state-owned resource loss, gives to produce and also brings potential safety hazard.Simultaneously along with country to northern heating charging policy reform, some areas have been taked the way of heating single home metering charge.Though have good policy and way to guarantee the warming of resident family; but still have minority resident family not pay or refuse to pay heating fee; for the interests of protection heating unit are not encroached on; the heating unit has taked various measures; but because of valve does not have effective anti-theft device; still minority resident family is not paying the heating resource of usurping the heating unit under the heating fee situation, causes the heating cost per unit to increase.
The model utility content:
In order to solve the problem of existing valve anti-theft effect difference, the utility model provides a kind of strong magnetic valve for guarding against theft, and this strong magnetic valve for guarding against theft has good anti-theft effect, characteristic of simple structure.
The technical solution of the utility model is: this strong magnetic valve for guarding against theft comprises the nut of valve body by being threaded, be connected with valve rod in the nut, the valve body upper cap nut is equipped with the valve gap stealingproof sleeve outward, the annular groove that reaches the valve gap stealingproof sleeve in the nut radial hole is equipped with magnet steel, the valve rod upper end is covered with outer hexagonal valve rod Anti-theft cap that is, valve rod upper end eccentric opening is built-in with the transmitting torque magnet steel, in the valve rod Anti-theft cap upper end with the transmitting torque magnet steel to blind hole should be arranged, in the valve rod radial hole and the annular groove of valve rod Anti-theft cap be equipped with position-limitting pin.
The utlity model has following beneficial effect: this strong magnetic valve for guarding against theft is owing to take such scheme; because of outside the valve body upper cap nut, being equipped with the valve gap stealingproof sleeve and being covered with the valve rod Anti-theft cap in the valve rod upper end; under no special tool situation, can only rotate valve gap stealingproof sleeve and valve rod Anti-theft cap like this; can't realize the purpose of rotation valve rod; thereby reach antitheft purpose; effectively protect the heating resource of state-owned resource and heating unit, and simple in structure, had the characteristics of application.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
1-nut 1 among the figure, 2-valve body, 3-valve rod, 4-valve gap stealingproof sleeve, 5-magnet steel, 6-transmitting torque magnet steel, 7-valve rod Anti-theft cap, 8-blind hole, 9-position-limitting pin.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this strong magnetic valve for guarding against theft comprises the nut 1 of valve body 2 by being threaded, be connected with valve rod 3 in the nut 1, the valve body 2 upper cap nuts 1 outer valve gap stealingproof sleeve 4 that is equipped with, the annular groove that reaches valve gap stealingproof sleeve 4 in nut 1 radial hole is equipped with magnet steel 5, magnet steel 5 is stuck in the annular groove of valve gap stealingproof sleeve 4, valve gap stealingproof sleeve 4 and nut 1 are linked together, valve gap stealingproof sleeve 4 can only radially rotate along nut 1, can't move up and down, more can not unload, can only just can unload with special tool, the effective like this valve rod 3 of having protected makes thief can't steal the heating resource of state-owned resource and heating unit; Valve rod 3 upper ends are covered with outer hexagonal valve rod Anti-theft cap 7 that is; valve rod 3 upper end eccentric openings are built-in with transmitting torque magnet steel 6; with transmitting torque magnet steel 6 corresponding parts blind hole 8 is arranged in valve rod Anti-theft cap 7 upper ends; the annular groove that reaches valve rod Anti-theft cap 7 in valve rod 3 radial holes is equipped with position-limitting pin 9; position-limitting pin 9 on the valve rod 3 is stuck in the annular groove of valve rod Anti-theft cap 7; valve rod 3 and valve rod Anti-theft cap 7 are linked together; valve rod Anti-theft cap 7 also can only radially rotate along valve rod 3; can't move up and down; more can not unload; can only when unloading bottom flange stealingproof sleeve 4, just can unload; when the needs switch valve; according to the magnet principle that there is a natural attraction between the sexes, in the blind hole 8 in the 6 inspiration transmitting torque magnet steel 6 of the transmitting torque magnet steel in the valve rod 3 upper end eccentric openings, pass through Hexagon rotary valve rod Anti-theft cap 7 simultaneously by special tool; form moment of torsion; reach the purpose of valve switch, the effective like this valve rod 3 of having protected makes thief can't steal the heating resource of state-owned resource and heating unit.This strong magnetic valve for guarding against theft has good anti-theft effect, characteristic of simple structure thus.
