Abstract
The utility model discloses an electric device for partially rotating a valve, comprising a box body forming an electric cavity and an electric appliance element installed in the electric cavity, wherein a wiring box which is communicated with the electric cavity, is relatively independent from the electric cavity is arranged at the outer side of the box body, and comprises a wiring box body, a wiring box cover and a terminal board; the wiring box body and the wiring box cover form a wiring cavity; the terminal board is arranged in the wiring cavity and the two ends of the terminal board can be respectively connected with a cable and the electric appliance element; a plurality of cable inlet holes are formed in the wiring box body; and the terminal board is arranged in a channel leading to the electric cavity; and the wiring cavity and the electric cavity are separated mutually by a sealing piece. In the electric device, due to the separation between the electric cavity and the wiring cavity, the damage of water to electric elements caused by non-normal operation in the wiring process is effectively prevented. Stripy terminal boards are omitted in the electric cavity, therefore, the space for stroke control and adjustment as well as torque control and adjustment of the electric device is larger, and debugging is facilitated.
Description
Technical field
The utility model relates to industrial valve, is a kind of part turning valve Electric actuator specifically.
Background technique
Part turning valve Electric actuator is a kind of electronic product that butterfly valve, ball valve, stopcock etc. are made 90 ° of turning valve switches of controlling.Because part turning valve Electric actuator is widely used in industrial sites such as oil, chemical industry, power plant, water treatment, metallurgy, complicated site environment requires product to have very high reliability.
As shown in Figure 1, in the prior art, part turning valve Electric actuator comprises the casing 20 that forms electric chamber 22 and is installed in electrical apparatus element 24 in the electric chamber 22 that be provided with long cable section of ingoing line hole 23 in the side of casing 20, bar shaped terminal board 21 is arranged in the electric chamber 22.Cable is introduced by wire-feeding hold 23, passes the inlet wire space, receives at last on the bar shaped terminal board 21.This mode of connection need be opened the casing of part turning valve Electric actuator in wiring; make electric chamber 22 expose out completely; structurally electric chamber 22 communicates with 23 inside, long cable section of ingoing line hole simultaneously; in case just caused wire-feeding hold 23 not protect at the scene, steam has just directly entered electric chamber 22 along cable.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of part turning valve Electric actuator that the operation water that causes lack of standardization influences electric elements in the wiring process that stops is provided.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of part turning valve Electric actuator, comprise electric chamber, casing and be installed in electrical apparatus element in the electric chamber, have with electric chamber in the casing arranged outside to communicate but relatively independent junction box.
Described junction box comprises the wiring casing that forms wire connection cavity and wiring case lid, be installed in the terminal board that the two ends in the wire connection cavity can be connected respectively with elastic cable paper and electrical apparatus element, on the wiring casing, be formed with a plurality of long cable section of ingoing line hole, terminal board is installed in and leads on the passage in electric chamber, and seals wire connection cavity is relative with electric chamber by Sealing.
The terminal board that is installed in the wiring box house is the round nose daughter board, and the round nose daughter board is fixed in the wiring casing by the terminal board hold down gag, and described Sealing is the O RunddichtringO.
Described long cable section of ingoing line hole is 3.
The beneficial effects of the utility model are: sealing relatively between electric chamber and the wire connection cavity has effectively stoped in the wiring process damage to electric elements of water that operation grade lack of standardization causes.Need not open the casing in electric chamber in the wiring process, make the IP protection of product more effective.Terminal board has more wiring with respect to the bar shaped terminal board counts, and the wiring between electric chamber and the wire connection cavity is simultaneously finished in factory, and wiring is standard more.Removed the bar shaped terminal board in the electric chamber, it is bigger that the Stroke Control adjustment of Electric actuator and Torque Control are adjusted the space, made things convenient for debugging.
Description of drawings
Fig. 1 is the structural representation of the part turning valve Electric actuator of prior art.
Fig. 2 is the structural representation of part turning valve Electric actuator of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
The working principle of part turning valve Electric actuator of the present utility model is identical with prior art, can be with reference to prior art, so no longer narration, the utility model and the difference of prior art are that junction box's structure is different, are described in detail below:
As shown in Figure 2, part turning valve Electric actuator of the present utility model comprises electric chamber 6, casing 10 and is installed in electrical apparatus element 9 in the electric chamber 6, has with electric chamber 6 in casing 10 arranged outside to communicate but relatively independent junction box.
Specifically, described junction box comprises the wiring casing 1 that forms wire connection cavity 7 and wiring case lid 2, be installed in the terminal board 3 that the two ends in the wire connection cavity 7 can be connected respectively with elastic cable paper and electrical apparatus element, on wiring casing 1, be formed with a plurality of long cable section of ingoing line hole 5, terminal board 3 is installed in and leads on the passage in electric chamber 6, and passes through Sealing 8 with wire connection cavity 7 and the 6 relative sealings of electric chamber.
In the present embodiment, the described wiring casing 1 inner round nose daughter board 3 of installing, described Sealing 8 is an O type seal ring.Described terminal board hold down gag 4 is fixed on round nose daughter board 3 on the wiring casing 1 by screw for the pressing plate of annular, and the O RunddichtringO by the below can not enter in the electric chamber 6 air outside and steam wire connection cavity 7 and the 6 relative isolation of electric chamber.Long cable section of ingoing line hole 5 in the present embodiment is 3.
The utility model removes the bar shaped terminal board that prior art part turning valve device is placed in electric chamber, a junction box is installed on casing, forms an independently wire connection cavity, make it to keep apart fully with electric chamber, cable is introduced by three wire-feeding hold places, finishes terminal block in wire connection cavity.Steam that this moment is outside and the electric elements in the electric chamber are isolated fully.
Above-described embodiment only is used to illustrate technological thought of the present utility model and characteristics, its purpose is to make those skilled in the art can understand content of the present utility model and implements according to this, can not only limit claim of the present utility model with present embodiment, be equal variation or the modification that spirit that all the utility model disclose is done, still drop in the claim of the present utility model.
