Technical field

The utility model belongs to anti-theft device, particularly relates to a kind of fixed point pipeline permanent magnetism screws valve for preventing illagel application.

Background technique

At present, Chang Yong mouth of pipe plug or cock are used for the shutoff mouth of pipe; Because it only depends on its common screw thread to twist and is connected on the mouth of pipe, be easy to rely on general tool to pull down, and cause plug or cock is robbed or burgled and liquid in pipe is run off.At the pipeline inner fluid is under the fire good or the situation of corrosive liquids, and mouth of pipe plug or cock robbed or burgled also will be caused serious consequences such as the economic loss that is difficult to expect or personal injury.In the pipeline (net) of or corrosive liquids inflammable in above-mentioned conveying, it is very necessary using a kind of antitheft orifice sealing device of robbed or burgled permanent magnetism that can prevent.

Summary of the invention

Technical problem underlying to be solved in the utility model is, can easily cause plug or the robbed or burgled situation of cock with the common tool dismounting at plug at present commonly used or cock, the purpose of this utility model is to provide a kind of fixed point pipeline permanent magnetism screws valve for preventing illagel application that uses special tool to dismantle that has only, robbed or burgled to prevent plug or cock, stop because of plug or robbed or burgled economic loss that causes of cock and human injury.

Fixed point pipeline permanent magnetism screws valve for preventing illagel application of the present utility model is made of plug tubing string, capping down, the core of the card, card cap and box spanner, and the end opening of plug tubing string embeds capping down and fixes the sealing cooperation and is one; The lower prop Spielpassung seat of the core of the card is in the core chamber of capping down, have following capping tube wall suitable for reading and to be mutually intersection, deep mixed, the twice draw-in groove that laterally runs through, the intersection of being mutually is arranged on the lower prop of the core of the card, highly differ, run through cylinder, all can with two bayonet locks of draw-in groove contraposition.The card cap is embedded in the plug tubing string, its bed seat on the upper port plane of capping down, the outer shoulder of its cylinder and plug tubing string inner shoulder table suitable for reading clamping spacingly movablely cooperates mutually, its end opening tube wall has with embeddable draw-in groove of bayonet lock phase contraposition and the core of the card on be embedded with magnetic patch last cylinder insert in the interior pipe that blocks cap, the external wall of upper portion of blocking cap is prismatic; The last cylinder of box spanner is inserted with plate and the top of, lower prop inner chamber is embedded with magnetic patch and this inner chamber becomes rib tubulose with the prismatic cooperation of convex-concave mutually of card cap.

The beneficial effects of the utility model: have only the permanent magnetism anti-theft sealing device that uses special tool to dismantle, robbed or burgled to prevent plug or cock, stop because of plug or robbed or burgled economic loss that causes of cock and human injury.

Embodiment

Embodiment 1

Fixed point pipeline permanent magnetism screws valve for preventing illagel application of the present utility model is made of plug tubing string, capping down, the core of the card, card cap and box spanner, and the end opening of plug tubing string 1 embeds capping 2 down and fixes the sealing cooperation and is one; The lower prop Spielpassung seat of the core of the card 3 is in the core chamber of capping 2 down, have following capping 2 tube walls suitable for reading and to be mutually intersection, deep mixed, the twice draw-in

groove

11,12 that laterally runs through, the intersection of being mutually is arranged on the lower prop of the core of the card 3, highly differ, run through cylinder, all can with two bayonet locks 4 of draw-in

groove

11,12 contrapositions; Card cap 5 is embedded in the plug tubing string 1, its bed seat on the upper port plane of capping 2 down, the outer shoulder of its cylinder and plug tubing string 1 inner shoulder table suitable for reading clamping spacingly movablely cooperates mutually, its end opening tube wall has with embeddable draw-in groove 13 of bayonet lock 4 phase contrapositions and the core of the card 3 on be embedded with magnetic patch 6 last cylinder insert in the interior pipe that blocks cap 5, the external wall of upper portion of blocking cap 5 is prismatic; The last cylinder of box spanner 7 be inserted with plate 8, the top of lower prop inner chamber is embedded with

magnetic patch

9 and 10 one-tenth rib tubuloses that cooperate with the prismatic convex-concave mutually of card cap 5 of this inner chamber.

Embodiment 2

Fixed point pipeline permanent magnetism screws valve for preventing illagel application of the present utility model, plug tubing string, capping down, the core of the card, card cap and box spanner constitute:

Shown in Fig. 2 a, 2b, described card cap 5 is the cylindrical shape of hollow, the one end seals, the other end opens wide, have four center lines on the barrel of its open end and be mutually the draw-in groove 13 of 90 ° of angles, its outer wall middle part is formed with the outer ring step that can join with the inner flanch of plug tubing string 1, and the cross-sectional circumference figure of its closed end is the square of chamfering;

As shown in Figure 3, described the core of the card 3, cylindrical, be fixed with magnetic patch 6 in the groove that this cylindrical body top is opened, in the open-work that open in this cylindrical body middle part and bottom two are mutually spatial vertical, be connected with the bayonet lock of outwards giving prominence to 4 and 14 separately;

Shown in Fig. 4 a, 4b, described capping 2 down, it is the hollow circle tube that the end is arranged that an end opens wide, the periphery wall of its bottom is provided with outwards outstanding circular protrusion, have two draw-in

grooves

11,12 that are mutually 90 ° of angles of cut on the barrel of its open end, and the difference h of the central shaft height of this two draw-in

groove

11 and 12 equals two bayonet locks 4 on the aforementioned the core of the card cylindrical body and the difference H of 14 height.

The assembly relation of each constituent elements of described fixed point pipeline permanent magnetism screws valve for preventing illagel application is as follows: described the core of the card 3, to be inserted into down in the inner chamber of capping 2 under magnetic patch 6 condition up, make the bayonet lock 4 of the bottom of the core of the card 3 embed the deep trouth 12 of capping 2 barrels down, and the top bayonet lock 14 of the core of the card 3 is rabbeted in the shallow slot 11 of following capping 2 barrels; Described card cap 5, its open end are placed on down downwards on the top of capping 2; Described plug tubing string 1 is buckled downwards from card cap 5 tops and its inwardly outstanding annular projection contact with the middle part ring-shaped step of card cap, and the outside annular projection of giving prominence to becomes crimping, solid welding on the lower end surface that makes plug tubing string 1 and the lower cover bottom wall.

Described box spanner 7 has an outer wall with the closed end of aforementioned card cap 5 at the one end and becomes the inner chamber 10 that can insert cooperation, and be embedded with magnetic patch 9 in second groove that the middle part of described inner chamber 10 has; And the other end has one and is used to insert plate 8 open-work on cylinder, perhaps has two orthogonal open-works.

Twist when being connected on the mouth of pipe will locking plug, essentially use special-purpose box spanner 7.During use, the upper end that is socketed in card cap 5 with box spanner 7, attract to move up at the core of the card 3 that will be contained under 9 the effect below the card cap 5, the middle part bayonet lock 14 on the core of the card 3 is embedded in the draw-in groove 13 of card cap 5, the following bayonet lock 4 of the core of the card 3 then still is positioned at dark groove 12 tops of time closing cap 2.Because plug tubing string 1 is that welding forms one with following capping 2, and card cap 5 is when becoming to turn rotation with plug tubing string 1, the core of the card 3 just drives capping 2 down, thereby drives plug tubing string 1 rotation synchronously.

And when without box spanner 7 turn card caps 5, because the core of the card 3 is with block between the cap 5 can not carry-over moment, so sheath can only dally and capping 2 and plug tubing string 1 under can not turn.
