Abstract
The utility model relates to an explosion isolating structure for electric valve locators and electric converters. The explosion isolating structure for electric valve locators and electric converters is composed of a bottom plate 1, a machine core component 5, and a junction box component 6. A cover plate 9 and a coil rack 10 are fixed to form a surface explosion isolating face 28. A cylinder 32 on a junction box 22 is matched with the bottom plate 1 to form a cylindrical explosion isolating face 29. A junction box cover 17 is connected to the junction box 22 through thread to form a thread explosion isolating face 30. A packing piece 21 and a rubber ring 20 are arranged in the hole of the junction box 22. The packing piece 21 and the rubber ring 20 are connected with a connector 19 through the thread to form the thread explosion isolating face 31. The utility model has the advantages of convenient regulation, simple structure, good explosion isolating effect, etc.
Description
The utility model relates to a kind of electropneumatic valve positioner, electropneumatic transducer explosion separation structure.
The flame proof of original electropneumatic valve positioner and electropneumatic transducer adopts overall structure, makes the explosion separation structure complexity, and processing accessories is many, and volume weighs greatly, makes to make complexity, processing cost height.Adopt the positioning work piece of whole flame proof and transducer not to open the table lid and carry out field adjustable, make the adjustment inconvenience in the occasion that inflammable gas is arranged.Because whole flame proof, explosion suppresion surface is more, and particularly the cylndrical surface flame proof rotates for a long time, adds wearing and tearing, and each gap, joint is increased, and reduces the flame proof effect.The coil of core part is to use enameled cable on plastic support in addition, because the insufficient strength of plastics obviously reduces the fastness of coil carrier.
The purpose of this utility model provides electropneumatic valve positioner, the electropneumatic transducer explosion separation structure that a kind of adjustment is convenient, simple in structure and flame proof is effective.
The utility model is made up of base plate 1, core part 5 and terminal box parts 6, core part 5 by coil 13, cover plate 9, diode 12, draw electric wire 11 and coil carrier 10 is formed, terminal box parts 6 are made up of connecting terminal members 23, terminal box 22, connector cover 17, seal ring 20 and pad 21, cover plate 9 and the coil carrier 10 fixing plane flameproof surfaces 28 that form; Cylindrical body 32 on the terminal box 22 forms cylinder explosion suppresion surface 29 with cooperating of base plate 1; Connector cover 17 forms threaded flame-proof type face 30 by being threaded on the terminal box 22; Pad 21 and rubber ring 20 are arranged in the hole of terminal box 22 and be threaded and form threaded flame-proof type face 31 with joint 19.
Below in conjunction with accompanying drawing the utility model is further described below.
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the structural drawing of core part 5.
Fig. 4 is the structural drawing of connecting terminal members 23.
Insulating paper 14 usefulness sealing compounds 15 are stranded on the cylinder of metal cover board 9, use enameled cable again on the cylinder of cover plate 9, enameled cable and metal cover board 9 insulation like this, constituted a coil 13, two diodes 12 of on the coil 13 that winds, burn-oning, weld the both positive and negative polarity electrical signal and draw electric wire 11, the anodal red electric wire, the blue electric wire of negative pole used.On coil 13 planes, coat sealing compound 15, cover plate 9 tightly is screwed in coil carrier 10, form the plane flameproof surface 28 of cover plate 9 and coil carrier 10 with 4 screws 16.Two screws 2 of coil carrier 10 usefulness and pad, spring washer are fixed on the base plate 1, core part 5 is fixed on the base plate 1.Establish 4 cylindrical bodys 3 at coil carrier 10 four jiaos, can increase the area of contact of coil carrier 10 and base plate 1 like this, make core part 5 stable more, reliable with the plane flame proof of base plate 1.Base plate 1, coil carrier 10 and cover plate 9 usefulness aluminium alloy compression castings form.
Connecting terminal members 23 is made up of tenminal block 4, screw 26, pad and wire terminal 7, with screw 27 and packing ring and spring washer connecting terminal members 23 is fixed on the terminal box 22.Be connected on respectively on the both positive and negative polarity of tenminal block 4 drawing electric wire 11 from two both positive and negative polarities of the diode in the core part 5 12, and fixing with screw 26, compression spring and wire terminal 7.In terminal box 22 holes at electric signal interface place, pad 21, rubber ring 20 are arranged, form threaded flame-proof type face 31 firmly fixing by being threaded, after joint 19 screws in terminal boxes 22 holes, makes rubber ring 20 pressurizeds from external electrical signal joint 19, endoporus is received little, and cable is pushed down firmly.Connector cover 17 is tightened on the terminal box by being threaded, form threaded flame-proof type face 30, O RunddichtringO 18 is installed on connector cover 17 in addition, prevent that dust, rainwater from entering terminal box 22, locking quick-fried nail 25 on the fastening connector cover 17 can prevent thread looseness.Cylindrical body 32 on the terminal box 22 forms cylinder explosion suppresion surface 29 with cooperating of base plate 1, and O RunddichtringO 24 is housed on the cylindrical body on the terminal box 32, prevents that dust, rainwater from entering explosion suppresion surface, with screw 8 and pad terminal box parts 6 is fixed on the base plate 1.
The utility model adopts local flame proof at core part 5 and terminal box parts 6, has cancelled whole flame proof, therefore makes adjustment more convenient, and is simple in structure, and the flame proof effect is better.
