Abstract
The utility model relates to gate valves, particularly to an anti-theft gate valve, which includes an anti-theft cover (3), wherein a dust cover (1) is arranged at the upper end of the anti-theft cover (3); a combination lock (2) is arranged at the upper part in an inner chamber of the anti-theft cover (3); grooves (18) are arranged at the upper part on the outer wall of an upper cover (13); the lower end of the anti-theft cover is clamped in the grooves (18) from the top down; and welding points (21) are formed between the inner wall of the anti-theft cover (3) and the upper cover (13) through welding, so as to fixedly connect the anti-theft cover (3) and the upper cover (13) into a whole. In the anti-theft gate valve provided by the utility model, the upper cover and the anti-theft cover are cast respectively, and can be welded into a whole after four inner wall threads of a filler chamber are machined, so that the machining is convenient, and the machining accuracy is high.
Description
Technical field
The utility model relates to gate valve, is a kind of gate valve of antitheft specifically.
Background technique
To use blank all be that loam cake is directly cast with pilferproof closure is an integral body to theft-proof gate valve in the market; Because theft-proof gate valve all is just can become finished product through the machined into packing cavity with blank; Need in packing cavity, process four inner threads with cutter through lathe during the prepared filler chamber; And because certain length is stamped in antitheft; The prepared filler chamber must get in the loam cake from square opening on the pilferproof closure again and remove four inner threads in prepared filler chamber, so just brings certain degree of difficulty to processing, is embodied in:
1, bad measurement operative position.
2, lathe for machining need reach certain-length with cutter, and tool length is long more, and difficulty is big more.
3, influence processing accuracy rate and time expand.
The model utility content
To the defective that exists in the existing technology, the purpose of the utility model is to provide a kind of gate valve of antitheft, and is easy to process, accuracy rate is high.
For reaching above purpose, the technological scheme that the utility model is taked is:
A kind of gate valve of antitheft is characterized in that, comprising:
Top in pilferproof closure 3 inner chambers is provided with cipher lock 2,
The top of loam cake 13 outer walls is provided with groove 18,
The lower end 4 of pilferproof closure snaps in groove 18 from top to bottom,
And it is an integral body that the inwall of pilferproof closure 3 is fixedly connected the two through welding formation solder joint 21 with loam cake 13.
On the basis of technique scheme, upper left, following, upper right, four inner threads 16 in bottom right in a left side that distribute in the packing cavity 15 of said loam cake 13,
Be provided with valve rod 17 in the packing cavity 15 between two parties,
The left and right sides of valve rod 17 is respectively equipped with valve rod location piece 12, and valve rod location piece 12 is following with a left side, two inner threads 16 in bottom right are threaded,
Valve rod location piece 12 tops are provided with asbestos 11,
The gate valve of the described antitheft of the utility model is cast loam cake and pilferproof closure respectively, behind four inner threads of intact packing cavity to be processed, the two is welded as a whole again, and is easy to process, accuracy rate is high.
Description of drawings
The utility model has following accompanying drawing:
The structural representation of Fig. 1 the utility model,
The structural representation of Fig. 2 pilferproof closure,
The structural representation of Fig. 3 loam cake.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explain.
Like Fig. 1,2, shown in 3, the gate valve of the described antitheft of the utility model comprises:
Top in pilferproof closure 3 inner chambers is provided with cipher lock 2,
The top of loam cake 13 outer walls is provided with groove 18,
The lower end 4 of pilferproof closure snaps in groove 18 from top to bottom,
And it is an integral body that the inwall of pilferproof closure 3 is fixedly connected the two through welding formation solder joint 21 with loam cake 13.
On the basis of technique scheme, upper left, following, upper right, four inner threads 16 in bottom right in a left side that distribute in the packing cavity 15 of said loam cake 13,
Be provided with valve rod 17 in the packing cavity 15 between two parties,
The left and right sides of valve rod 17 is respectively equipped with valve rod location piece 12, and valve rod location piece 12 is following with a left side, two inner threads 16 in bottom right are threaded,
Valve rod location piece 12 tops are provided with asbestos 11,
The gate valve of the described antitheft of the utility model; At first to cast loam cake and pilferproof closure respectively; Packing cavity inner thread in the reprocessing loam cake; After machining, make and directly insert below its pilferproof closure on the loam cake groove having groove above the loam cake, weld through electric welding in pilferproof closure and loam cake joint that to make its strong bonded be one.
The content of not doing in this specification to describe in detail belongs to related domain professional and technical personnel's known prior art.
