CN205298778U - Novel cauldron bottom valve door -trip handle - Google Patents

Abstract

The utility model discloses a cauldron bottom valve door -trip handle. It is exactly cauldron bottom valve door at reation kettle's bottommost to use reation kettle at present in chemical industrial production process plentifully, and cauldron bottom valve door is most apart from 2 to 3 BRATs on the ground, and operating personnel stands at subaerial unable direct switching valve, need stand at the enterprising line operate of ladder, and is very inconvenient, also not too safe. The utility model discloses the handle is exactly 2.5 meters long, and 0.2 meter long is burn -on for 20 2.5mm's of phi steel pipe one end to the model, and the model is the nozzle stub of 32 3.5mm of phi slope. Handheld this novel handle only need be stood and just can easily be carried out on -off operation, very convenient, safety to cauldron bottom valve door subaerial. The present invention uses the technical scheme, the utility model discloses there is following advantage: 1, do not need the operation of ascending a height of cat ladder, relatively more convenient, safety, 2, because this novel handle is equivalent to the former cauldron bottom valve door -trip handle of extension, operate lightlyer.

Description

A kind of Novel kettle-bottom switch handle of valve

Technical field

The handle of this utility model bottom valve can be widely applied to the switch of chemical field bottom valve. It is particularly suitable for vitamin B₁And vitamin B₆The switch of the Polycondensation Reactor and Esterification Reactor valve in synthetically produced process.

Background technology

Using chemical reaction kettle in chemical process in a large number at present, owing to bottom needs to install other the equipment such as centrifuge, sheet frame, therefore bottom needs to leave the space having about 2 meters from ground. When operator need switch bottom valve, it is necessary to by cat ladder, if imprudence is easily fallen down during upper and lower cat ladder, very dangerous. This utility model bottom switch handle of valve, only need to stand in ground just easily can carry out switching manipulation to valve.

Summary of the invention

The purpose of this utility model is that and overcomes the bottom valve of common switch eminence to need by cat ladder, the deficiency of operation inconvenience, it is provided that the handle (Fig. 1) of a kind of novel switched bottom valve.

The technical solution of the utility model is:

The handle of this novel switch bottom valve, it is exactly long at 2.5 meters, model is the short steel pipes 2 that steel pipe 3 top of �� 20 �� 2.5mm is burn-on 0.2 meter long, the diameter of short steel pipes 2 can be determined according to the width of bottom valve handle 3, slightly larger than this width, the middle part of short tube 2 is tilted 45 �� and is welded in its top.

Adopt technique scheme. This utility model has the advantage that operator stand in ground and hold this handle and just the bottom valve of eminence can be carried out switching manipulation, it is convenient to, it is not necessary to operation of ascending a height; Owing to this new type handle is equivalent to lengthen former bottom switch handle of valve, so the comparison that operates is light.

Accompanying drawing explanation

Fig. 1 Novel kettle-bottom switch handle of valve structural representation; Fig. 2 is that bottom valve is in novel switch handle of valve status figure during opening.

Detailed description of the invention

Long by 2.5 meters, model is the short steel pipes 2 that steel pipe 3 upper end of �� 20 �� 2.5mm is burn-on 0.2 meter long, and the diameter of short steel pipes 2 can be determined according to the width of bottom valve handle 3, slightly larger than this width, the middle part of short tube 2 is tilted 45 �� and is welded in its top. Such as Fig. 2, when bottom valve closed by needs, this new type handle being tilted 45 ��, short tube 2 is inserted in bottom valve handle 3, rotation new type handle 90 �� makes bottom valve handle 3 be in level;When bottom valve opened by needs, then carry out reverse operating, make bottom valve handle 3 be in vertical ground state.

Claims (2)

1. a novel bottom switch handle of valve, is characterized by: this handle is to be welded by a steel pipe 2.5 meters long (1) and a steel pipe 0.2 meter long (2).

2. the structure of handle according to claim 1, it is characterized in that: the short tube (2) of handle front end needs 45 �� of welding, the diameter of short tube can be determined according to bottom valve handle (3) width, slightly larger than valve handle, in general, using 0.2 meter long, model is that �� 32 �� 3.5mm steel pipe (2) can meet needs.
