Abstract
The utility model relates to a cable direct introducing device, characterized by comprising a plinth connected with a main casing, wherein a flame-proof cylinder is sleeved in the plinth, the faying surface by which the plinth is connected with the flame-proof cylinder is a flame-proof surface, the flame-proof cylinder is connected with a transition body equipped with a sealing ring and a rotating stop pad, and the transition body is connected with a locking body equipped with a sealing ring and a rotating stop pad. Advantages of the device are that a cable can be directly introduced into the main casing, no extra conjunction box or explosion-proof type binding post board needs to be arranged, connecting, wiring and installation of the device are simple and convenient, manpower is saved, and reliability is substantially improved. Besides, the device is small in size, thereby saving installation space. By adopting the device, a single product can save direct material cost by more than 50%, and thus, manufacturing cost is substantially reduced, and usage cost is reduced.
Description
Technical field
The utility model belongs to the electric device for valve technical field, the direct introducing device of particularly a kind of cable of flame-proof valve valve electric device.
Background technology
Usually, be used for the explosion-proof type electric device for valve that explosive gas atmosphere uses and be provided with cable entry.According to the regulation of standard GB 3836.2-2000 " explosive gas atmosphere electrical installation part 2: flame-proof type " d " ", cable has two kinds of connected modes: the first, introduce indirectly, with terminal box or plug assembly ways of connecting; The second, directly introduce, with the connected mode that inserts in the main shell.Adopt direct introducing mode must meet two conditions: not produce spark, electric arc or dangerous temperature when 1. normally moving; 2. rated power≤the 250W of electric equipment, but electric current is not more than 5A.In known technology; The general indirect introducing mode that adopts terminal box; Its specific practice is: terminal box is installed on the flame-proof valve valve electric device main box; The inner explosion-proof type terminal board of installing of said terminal box, terminal box is provided with cable and introduces and pressed sealing device, and connector cover is installed in the explosion-proof chamber that forms sealing on the terminal box.When above-mentioned cable introducing mode indirectly was used on the flame-proof valve valve electric device of motor rated power≤250W, its structure, volume were too huge, are unfavorable for installation, wiring, debugging; Terminal box, connector cover, explosion-proof type terminal board add that the production cost that cable is introduced and hold-down mechanism is formed is higher, have strengthened the user and have used burden.
Summary of the invention
The utility model provides a kind of simple in structure, easy for installation, direct introducing device of cable of using reliable and low cost of manufacture for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: the direct introducing device of cable; It is characterized in that: comprise the plinth that is connected with main box; Be set with the flame proof tube in the said plinth; The faying face of said plinth and flame proof tube is an explosion suppresion surface, and said flame proof tube connects the transition body that sealing ring is housed and only revolves pad in it, is connected with the locking body that sealing ring is housed in it and only revolves pad on the said transition body.
The utility model can also adopt following technical scheme:
The said plinth main box that is threaded.
The said flame proof tube transition body that is threaded.
The said transition body locking body that is threaded.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme; Cable can be introduced directly in the main box through this device; Need not to increase parts such as extra terminal box, explosion-proof type terminal board; Manpower is saved in its connection, wiring and install simple and conveniently, and reliability also greatly improves; In addition, this device volume is little, saves installing space; The separate unit product adopts this introducing device can save the direct material expense more than 50%, can reduce manufacturing cost significantly like this, alleviates user's cost of use.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, plinth; 2, flame proof tube; 3, transition body; 4, only revolve pad; 5, sealing ring; 6, locking body; 7, main box.
Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1; The direct introducing device of cable; Comprise the plinth 1 that is connected with main box 7, be set with flame proof tube 2 in the said plinth, said plinth 1 is an explosion suppresion surface with the faying face of flame proof tube 2; Said flame proof tube connects the transition body 3 that in it sealing ring 5 is housed and only revolves pad 4, is connected with the locking body 6 that sealing ring 5 is housed in it and only revolves pad 4 on the said transition body.In the present embodiment, the said plinth main box that is threaded, said flame proof tube adopt flame proof thread to connect the transition body, and said transition body adopts flame proof thread to connect locking body.Cable pass successively locking body 6, only revolve pad 4, sealing ring 5, transition body 3, sealing ring 5, only revolve in the endoporus of parts such as pad 4, flame proof tube 2 and plinth 1 and introduce, and the flame proof clay is inserted in the space between the cable of the endoporus of flame proof tube 2 and introducing.
Claims (4)
