Abstract
The utility model relates to an intelligent opening indicator window structure of a valve electric actuator, which comprises explosion-proof glass, a pressure ring and a sealing ring, wherein the explosion-proof glass is mounted in a control box enclosure, the pressure ring presses the explosion-proof glass tightly and the sealing ring is arranged between the pressure ring and the explosion-proof glass. The intelligent opening indicator window structure is characterized in that a hollow pressure plate is arranged inside the pressure ring, and mounted inside the control box enclosure through a fastening component. The fastening means with an elastic retainer ring for the intelligent opening indicator window structure compared with the prior art is omitted, the pressure plate and the pressure ring are fastened to press the explosion-proof glass by the fasteners, and the intelligent opening indicator window structure has the advantages of convenience in mounting and dismounting, fine sealing performance, safety, reliability and the like. Further, processing technique is simplified, manufacturing cost is reduced and production efficiency is improved. Explosion-proof control box enclosure, non-explosion-proof control box enclosure and the like are achieved by changing pressure rings of different lengths.
Description
Technical field
The utility model relates to and belongs to the electric device for valve technical field, particularly a kind of intelligent electric device for valve aperture indicating window structure.
Background technique
At present, intelligent control box cover not only has the visual aperture function of basic model control of product case cover, and its aperture indicating device is by using more advanced liquid crystal display panel to show, replacing original aperture direction board, can realize human-computer dialogue, the professional workforce's electric adjustment of being more convenient for.Particularly the structural requirement of explosion-proof type product aperture indicating window position is more strict, and is higher to its sealing, reliability requirement.
Known technology electric device for valve aperture indicating window structure adopts following structure, promptly, implosion guard is put into the control box cover, the implosion guard inboard is provided with pressure ring, be provided with seal ring between pressure ring and the implosion guard, the outside of pressure ring is provided with circlip, by circlip it is stuck in the control box cover, and compress pressure ring, realize the installation of aperture indicating window.
In use exposed a lot of problems in the known technology, main problem has: 1, circlip is difficult for installing; 2, the circlip fastening means is not firm, and gap value is big; 3, control box cover aperture indicating window structure relative complex, and be difficult for processing.
Summary of the invention
The utility model provides a kind of compact structure, easy installation and removal, good airproof performance, safe and reliable intelligent electric device for valve aperture indicating window structure for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of intelligent electric device for valve aperture indicating window structure, comprise the implosion guard that is installed in the control box cover, compress the pressure ring of implosion guard and the seal ring between pressure ring and the implosion guard, it is characterized in that: described inboard at pressure ring is provided with the hollow type pressing plate, and pressing plate is installed in control box cover inboard by clamp structure.
Advantage and the good effect that the utlity model has are: because the utility model adopts said structure, promptly be provided with the hollow type pressing plate in the inboard of pressure ring, pressing plate is installed in control box cover inboard by the fastening piece screw, realizes the installation of aperture indicating window.Advantages such as the utility model has compared with prior art been cancelled the fastening means of circlip, by fastening piece clam member and pressure ring, compresses implosion guard, has easy installation and removal, good airproof performance, and is safe and reliable; The utility model has also been simplified processing technology in addition, has reduced manufacture cost, has improved manufacturing efficiency; But also can be according to changing the different pressure ring of length, realize characteristics such as explosion-proof and non-explosion-proof control box cover is dual-purpose.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, control box cover; 2, implosion guard; 3, pressure ring; 4, seal ring; 5, pressing plate; 6, screw; 7, liquid crystal screen; 8, screw.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, a kind of intelligent electric device for valve aperture indicating window structure, comprise the implosion guard 2 that is installed in the control box cover 1, compress the pressure ring 3 of implosion guard 2 and the seal ring 4 between pressure ring 3 and the implosion guard 2, be provided with hollow type pressing plate 5 in the inboard of pressure ring 3, pressing plate 5 is installed in control box cover 1 inboard by clamp structure screw 6, and the inboard of pressing plate is a liquid crystal screen 7, and liquid crystal screen 7 is connected with pressure ring 3 with pressing plate 5 by fastening piece screw 8.
The advantages such as the utility model has compared with prior art been cancelled the fastening means of circlip, by securing member clam member and pressure ring, compresses implosion guard, has easy installation and removal, good airproof performance, and is safe and reliable; The utility model has also been simplified processing technology in addition, has reduced manufacturing cost, has improved production efficiency; But also can be according to changing the different pressure ring of length, realize the characteristics such as explosion-proof and non-explosion-proof control box cover is dual-purpose.
