Abstract
The utility model discloses a non-magnetic valve antitheft device, which comprises a polygonal valve stem arranged inside a polygonal housing. A fixed block is connected to the polygonal valve stem, a guide locking pin is arranged between the fixed block and the inner wall of the housing, a magnetic moving block is sleeved on the polygonal valve stem, one section of the magnetic moving block is polygonal, the polygonal section of the magnetic moving block corresponds to the inner wall of the polygonal housing, and a spring is arranged between the top face of the magnetic moving block and the inner top face of the housing. The non-magnetic valve antitheft device is high burglary prevention and confidentiality, is applicable to severe application environments and higher in safety requirement, especially to hydrants, is higher in reliability false operation and long in service life, and avoids false operation.
Description
Technical field
The utility model belongs to valve parts, is specifically related to a kind of valve anti-theft device.
Background technique
Valve for guarding against theft be mainly used in the pipe network system uncontrolled use often appears, on the terminal use of the usefulness of usurping and refuse to pay dues, the anti-theft device on the valve for guarding against theft of Shi Yonging and all used magnetic material on the key in the market.Because the valve Environmental Conditions is abominable, uncared for, the magnetic on the valve is very easily shaken, high temperature and artificial destruction and lost efficacy.
Summary of the invention
The purpose of this utility model is to provide a kind of valve not have the magnetic anti-theft device, to address the above problem.
The technical solution of the utility model is: it comprises the polygonal valve rod, the polygonal valve rod is located in the polygonal outer casing, be connected with fixed block on the polygonal valve rod, be provided with the guiding lock pin between fixed block and the outer casing inwall, be arranged with the magnetic conduction movable block on the polygonal valve rod, the magnetic conduction movable block has one section to be polygonal, and the polygonal section of magnetic conduction movable block is corresponding with polygonal outer casing inwall, is provided with spring between the end face of magnetic conduction movable block and the inner top surface of outer casing.
Described magnetic conduction movable block constitutes by at least two sections, and epimere is the annulus guide section, the polygonal linkage section that epimere is divided into, and wherein any one section or two sections is permeability magnetic material.
Described magnetic conduction movable block comprises at least two sections formations, and epimere is the annulus guide section, and the polygonal linkage section that epimere is divided into is inlaid with permeability magnetic material in wherein any one section or two sections.
It also comprises the base section that the polygonal linkage section is divided into.
Described base section is permeability magnetic material or is inlaid with permeability magnetic material.
This device anti-theft and security performance height.Be applicable to the occasion that Environmental Conditions is abominable, safety requirement is higher.Particularly use this device on the fire hydrant, reliability is higher, and there is not misoperation in its long service life.
Description of drawings
Fig. 1 valve does not have magnetic anti-theft device structural representation.
Fig. 2 valve does not have magnetic anti-theft device structure plan view.
Fig. 3 magnetic conduction movable block schematic representation.
Embodiment
As shown in Figure 1, valve rod 1 is a quadrilateral, is connected with fixed block 2 on the tetragonal valve rod 1, and the shape of the intermediate hole of fixed block 2 is corresponding with the shape of tetragonal valve rod 1, is connected by resilient key 4 between fixed block 2 and the valve rod 1.Valve rod 1 is located in the outer casing 6, outer casing 6 epimeres be shaped as polygonal, present embodiment outer casing 6 epimeres be shaped as pentagon (shown in Figure 2); Outer casing 6 inwalls have circular groove 8, and fixed block 2 is provided with pilot hole 9, are provided with spring 10 and guiding lock pin 3 in the pilot hole 9; Guiding lock pin 3 stretches in the circular groove 8, makes fixed block rotate and not quick detachable.
Be arranged with magnetic conduction movable block 5 on the valve rod 1, the quadrilateral hole of magnetic conduction movable block matches with the valve rod quadrilateral; Be provided with spring 7 between the inner top surface of the end face of magnetic conduction movable block 5 and outer casing 6.
Shown in Fig. 1,3, magnetic conduction movable block 5 is an annulus guide section 5.1 by epimere, the polygonal linkage section 5.2 that epimere 5.1 is divided into, the base section 5.3 that polygonal linkage section 5.2 is divided into; Any one section or any two sections or three sections is permeability magnetic material in the magnetic conduction movable block 5 of three-stage structure, and base section 5.3 is a permeability magnetic material iron in the present embodiment.Also can be in any one section or any two sections or three sections, to be inlaid with permeability magnetic material.
During use, Magnetic spanner is enclosed within on the polygonal section of outer casing 6, magnetic conduction movable block 5 is under the effect of Magnetic spanner, move up, make polygonal linkage section 5.2 cooperate with the polygonal section 6.1 of outer casing 6 inwalls, can rotate outer casing 6, rotate thereby drive valve rod 1 by magnetic conduction movable block 5, rising of realization valve closed; After Magnetic spanner was taken away, magnetic conduction movable block 5 fell under the effect of spring 7, and magnetic conduction movable block 5 polygonal linkage section 5.2 was mismatched with the polygonal section 6.1 of outer casing 6 inwalls and was connected this moment, and outer casing 6 rotations and valve rod 1 does not rotate realize antitheft effect.
