Description

Local environment adjusting device

Technical Field

The utility model relates to a local environment adjusting device is a device that keeps joint department stable in environment in pipeline dismantlement and installation.

Background

There are often special requirements in industrial production, especially in the production of pharmaceuticals, food, chemical and new materials, which is more common, such as the need for an environment that is anhydrous, oxygen-free, dust-free, sterile, etc. Dust-free, sterile environments have been implemented in the food and pharmaceutical industries. The method is generally finished by adopting large-scale sealing equipment such as a clean room, a sterile room and the like. Achieving the normal harsh environmental requirements by creating a large sealed environment is achievable, but typically results in high cost and maintenance. However, in some cases it becomes impractical to achieve this requirement through a large sealed environment, such as a simultaneous oxygen-free, water-free, dust-free environment, which is usually achieved by a miniaturized production facility, such as a glove box filled with inert gas. However, the glove box also has the problems that the glove box is inconvenient to move firstly, and pipelines cannot be realized, particularly the pipelines connected with large-scale rotary equipment are frequently disassembled and assembled. Of course, if the handle sleeve box is made to be very large, the first scheme is adopted, the manufacturing cost is high, the equipment maintenance cost is high, meanwhile, the safety risk exists, and the risk of poisoning and the like is easily caused by a pure nitrogen environment.

As shown in the figure, the two valves are usually required to be disassembled and butted due to process requirements, although the disassembly is realized after the valves are closed, water and oxygen exist in the air between the valves when the two valves are butted, and the performance and the quality of the product are still obviously influenced in seasons with high humidity.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an effectively keep joint stable in environment's local environment adjusting device.

The technical solution of the utility model is that:

a local environment adjusting device is characterized in that: comprises a left tube-shaped object and a right tube-shaped object which are respectively arranged on a left pipeline and a right pipeline which are connected with a left valve and a right valve; the left and right cylindrical objects are respectively arranged at the contact parts with the left and right pipelines and form a sealing structure with the outer walls of the pipelines through sealing materials; the contact surfaces of the left and right cylindrical objects form a joint sealing structure through a sealing material, one part of the left cylindrical object is a flexible ring made of a flexible material, and the flexible ring can stretch and retract along the direction of the cylindrical wall; the left and right cylindrical objects are respectively provided with left and right sealed gloves which are hermetically connected with the cylindrical wall into a whole and can extend into the cylindrical objects for operation; and a valve which is communicated with the interior of the cylinder and is used for filling nitrogen and/or vacuumizing is arranged on the wall of one or two of the left and right cylinders.

The sealing material is silica gel or silicone grease.

The utility model discloses can dismantle and the effective stable environment that keeps in joint department of low cost in the installation at the pipeline, working property is good.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

Fig. 2 is a schematic diagram of another embodiment.

Detailed Description

A local environment adjusting apparatus includes left and right cylinders 1, 2 installed on left and right pipes connected to left and right valves (A, B), respectively; the left and right two cylinders are respectively arranged at the contact parts (E/F) of the left and right pipelines and form a sealing structure with the outer wall of the pipeline through a sealing material; the left and right cylinder contact surfaces (G/H) form a joint sealing structure through a sealing material, one part of the left cylinder is a flexible ring (CD) made of a flexible material, and the flexible ring is in a telescopic mode along the direction of the cylinder wall; the left and right tubular objects are respectively provided with left and right sealed

gloves

3 and 4 which are hermetically connected with the tubular wall into a whole and can extend into the tubular objects for operation; and a valve which is communicated with the interior of the cylinder and is used for filling nitrogen and/or vacuumizing is arranged on the wall of one or two of the left and right cylinders.

The sealing material is silica gel or silicone grease and the like.

The operation process is as follows:

1. the valve A, B is held close to, but not firmly abutted, leaving a sufficient gap.

2. And stretching the flexible ring CD, extending the left barrel, butting the sealing surface G/H, and sealing the sealing surface E/F.

3. Pumping gas through a valve I and filling nitrogen; then pumping gas, and filling nitrogen for replacement until the gas quality reaches the standard.

4. And closing the valve I.

5. And (5) butting the valve A, B, screwing a bolt, fastening and completing butting.

In another embodiment:

as shown in FIG. 2, a short circuit is added between A, B two valves, a side is opened on the short circuit to connect valve I (or two valves are separated to realize inflation and deflation), and the air remained when A, B valves are connected is replaced by valve I.

The operation process is as follows:

1. the A, B valve is firmly connected by a short circuit.

2. Pumping gas through a valve I and filling nitrogen; then pumping gas, and filling nitrogen for replacement until the gas quality reaches the standard.

4. And closing the valve I, and finishing the butt joint.
