Background technique
The ordinary ball valve series products of existing market all adopts handle arrangement, easily opened and closed arbitrarily, there is afterwards part magnetic locking valve to appear on the market, as the ball valve of magnetic lockable, it adopts magnetic spool, at the surface of shell open keyhole of spool, lockhole is embedded in magnetic bullet, bonnet is installed on it, by the Magnetic spanner coordinating with bonnet, is realized being pressed into and ejecting of pellet, thereby reach the locking functions of ball valve.But common magnet or similar magnetic article for most of magnetic lock valve, still can open or close, and anti-theft effect is not good.For the charge of the enterprises such as water supply air feed, this is a problem demanding prompt solution.
Summary of the invention
The purpose of this utility model is to provide a kind ofly carries out coding and sorting order to same magnet, and ordinary person cannot carry out the common locking valve that has cracked keying.
The purpose of this utility model is achieved in that a kind of locking valve, comprise valve body, handle, bonnet, be placed in the valve rod of valve body, the lower end of valve rod is connected with valve ball, valve gap is fixedly connected with by pin with valve rod, stifled pin seal gap, valve gap coordinates handle to rotate, drive valve ball open or close, wherein, the part of described valve body parcel valve rod and valve gap lower end surface are respectively provided with four and are uniformly distributed and symmetrical and corresponding lockhole, in each unit lockhole, be provided with elastic component and magnetic part A, and can be subject to the effect of external force up and down, and the upper end magnetic pole with the magnetic part of medial axis symmetry is contrary, clockwise direction upward magnetic is followed successively by the arctic, the arctic, the South Pole, the South Pole, in the middle of two arctic, be provided with red some mark, on described handle, be embedded with four magnetic part Bs corresponding with magnetic part A in described lockhole, the lower end magnetic pole of described four magnetic part B distributes and distributes identical with the upper end magnetic pole of described four magnetic part A, clockwise direction is followed successively by the arctic, the arctic, the South Pole, the South Pole towards lower magnetic pole, is provided with equally red some mark in the middle of two arctic.During Open valve, two red some marks are aimed at, due to the principle of two like magnetic poles repel each other, magnetic part extruding elastic component in lockhole, sink in lockhole, valve gap is unlocked, rotatable 90 °, while reaching 90 °, half magnetic part two like magnetic poles repel each other extruding elastic component, there is a natural attraction between the sexes for half magnetic part, and elastic component is stretched, magnetic part relocks valve gap, cannot drive ball valve to be rotated further.
According to a kind of locking valve of the above, wherein, described magnetic part A supports by described elastic component, and under described elastic component nature, described magnetic part A one end is positioned at the lockhole of described valve body parcel valve stem part, the other end is positioned at the lockhole of described valve gap, and now, valve gap can not be rotated by locked.
According to a kind of locking valve of the above, wherein, in described valve body, be provided with seal washer, described seal washer is positioned at the both sides of described valve ball, improves sealing.
According to a kind of locking valve of the above, wherein, described elastic component is spring.
According to a kind of locking valve of the above, wherein, described magnetic part A and magnetic part B are magnet.
The utility model compared to existing technology outstanding and useful technique effect is: must must use the dedicated handle of the good magnetic pole of layout that matches just can to open or close, thereby improve the anti-theft security of ball valve, greatly reduce the risk of maliciously being opened; The angle that each handle opens and closes is all 90 degree, effectively opens and closes to extend to open and close working life; And simple in structure, cost of production is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is cross-sectional schematic of the present utility model;
Fig. 3 is the schematic top plan view in Fig. 2;
In figure: 1-valve body, 2-valve ball, 3-seal washer, 4-bonnet, 5-valve rod, 6-valve gap, 7-magnetic part A, 8-elastic component, 9-handle, 10-magnetic part B, 11-pin, the stifled pin of 12-.
Embodiment
Below in conjunction with accompanying drawing, with specific embodiment, the utility model is further described, referring to Fig. 1-3: a kind of locking valve, comprise valve body 1, handle 9, bonnet 4, be placed in the valve rod 5 of valve body 1, the lower end of valve rod 5 is connected with valve ball 2, and valve gap 6 is fixedly connected with by pin 11 with valve rod 5, stifled pin 12 seal gaps, valve gap 6 coordinates handle 9 to rotate, drive valve ball 2 open or close, in order to improve sealing, the both sides of described valve ball 1 are provided with seal washer 3.
The part of described valve body 1 parcel valve rod 5 and valve gap 6 lower end surfaces are respectively provided with four and are uniformly distributed and symmetrical and corresponding lockhole, in each unit lockhole, be provided with elastic component 8 and magnetic part A7, described elastic component 8 is spring, magnetic part A7 is magnet, and can be subject to the effect of external force up and down, and the upper end magnetic pole with the magnetic part of medial axis symmetry is contrary, and clockwise direction upward magnetic is followed successively by the arctic, the arctic, the South Pole, the South Pole, in the middle of two arctic, be provided with red some mark; On described handle 9, be embedded with four magnetic part B10s corresponding with magnetic part A7 in described lockhole, magnetic part B10 is magnet, the lower end magnetic pole of described four magnetic part B10 distributes and distributes identical with the upper end magnetic pole of described four magnetic part A, clockwise direction is followed successively by the arctic, the arctic, the South Pole, the South Pole towards lower magnetic pole, is provided with equally red some mark in the middle of two arctic.
Described magnetic part A7 supports by described elastic component 8, and under described elastic component 8 natures, described magnetic part A7 one end is positioned at the lockhole of described valve body 1 parcel valve rod 5 parts, and the other end is positioned at the lockhole of described valve gap 6, now, valve gap 6 can not be rotated by locked.
When red some mark on handle 9 aimed at the red some mark (or the arrow of carving characters) on valve gap, the pole orientation of the magnetic part B10 lower end of four embedded handles 9 of cause is all identical with the pole orientation that is arranged on four magnetic part A7 upper ends on valve body 1, two like magnetic poles repel each other, magnet in handle 9 is made reaction force to the magnet in valve body 1, Compress Spring, sink in lockhole, valve gap is unlocked, thereby handle with sleeve 9 has been realized the closure or openness of ball valve 2.But when handle 9 turns to 90 °, thereby because having occurred to change to each symmetrical position relation of four magnet in valve body 1, four embedded magnet of handle 9 make its magnet interaction, with counteractive direction, variation occur, half magnet two like magnetic poles repel each other extruding elastic component, there is a natural attraction between the sexes for half magnet, elastic component is stretched, magnet relocks valve gap, cannot drive ball valve to be rotated further, if continue changeover valve, must again handle 9 be adjusted, make red some mark and red some label alignment on valve body 1, again rotation on handle 9.
Above-described embodiment is only preferred embodiment of the present utility model, not limits according to this protection domain of the present utility model, therefore: all equivalences of doing according to structure of the present utility model, shape, principle change, within all should being covered by protection domain of the present utility model.
