Abstract

The utility model relates to an industrial quick opening /closing door composed of a movable door cover and a screw rod bolt sleeve; the movable door cover is provided with a compressing bolt, which is connected into integration; the screw rod bolt sleeve provided with a slot is screwed with a screw rod lock pin which can be sheathed on the compressing bolt. The utility model is used for devices of inspection doors, hand hole doors, human hole doors in the equipment or the system of electric power, chemical industry, petroleum, etc. to seal low pressure industrial media of gas, liquid, etc. The utility model has the advantages of convenient operation, easy fabrication, no leakage and high efficiency.

Description

Industry high-speed switch door

Industry high-speed switch door relates to the device of the inspection door that uses in commercial unit or the system, hand hole door, manhole door type.

Current in industries such as electric power, chemical industry, oil, use industrial door sealing low pressure working fluid, comprise gas, liquid or other fluid; Its airtight employing flange connecting mode, opening and closing are pretty troublesome, consumption worker feed consumption consuming time; And being difficult to guarantee airtight tight, the loss that the leakage that is produced causes is huge.

The utility model purpose is: provide a kind of industrial high-speed switch door, the defective of solve industrial door complicated operation in the prior art, easily leaking.

In conjunction with the accompanying drawings technical solutions of the utility model are described as follows: 1, constitute by valve lid 1 and screw mandrel bolt cover 3; 2, install with bolt or pin on the valve lid 1 and compress keeper 2 and be connected as a whole, be installed in the rotating shaft the valve lid 1 usefulness bolt or the pin that compress keeper 2 are housed; 3, the screw mandrel bolt that has a groove 5 puts spinning screw mandrel lock pin 4, and can put the non-rotating shaft union end that compresses keeper 2.During use, but cw or anticlockwise direction open or close the utility model; When opening, unscrew screw mandrel lock pin 4, the screw mandrel bolt of outwarding winding cover 3 compresses keeper and gets final product with pulling to open; Otherwise for shutting.

The utility model advantage is: simple in structure, be easy to make; Switch is convenient, does not need instrument; Never leak, tight-closed; Compare with other structure of ad eundem, withstand voltage higher, what be used for that the resistant to elevated temperatures leakproofing material of acid-fast alkali-proof oil resistant has is reusable, and need not of having changed.
