Description

Box body sealing device

Technical Field

This novel sealing device that belongs to, concretely relates to box is sealed.

Background

The sealed box room of a certain project is special in working environment, radioactive or toxic media are arranged in the sealed box room, the box room is required to be subjected to a sealing test according to the sealing grade 3 grade according to the drawing, the number of corresponding open type interfaces of the box room is very large, the working pressure in the box body is 200-300Pa, the pressure cannot be easily maintained when any interface leaks, the detection difficulty is large, the sealing test cannot be easily succeeded, only partial assembly welding can be performed in a manufacturing plant, partial open pipelines are arranged at the top, the side and the bottom of the box body, a double transfer cover and the like, butt welding or installation with an installation site is required, and the box body cannot be subjected to the sealing test in the plant.

SUMMERY OF THE UTILITY MODEL

The object of the present invention is to provide a device for sealing a tank, which overcomes the drawbacks of the prior art.

The novel adopted specific technical scheme is as follows: the utility model provides a device that box is sealed, wherein, includes bolt, nut and double-deck board, and wherein bolt, nut are used for compressing tightly the double-deck board, and the double-deck board is used for sealing the box.

A device for sealing a tank as described above, wherein the sealing means is provided between the double plates.

The tank body sealing device is characterized in that the sealing device is an o-ring or silicone.

The device for sealing the box body is characterized in that the silicone rubber is a silicone rubber gasket.

A tank sealing arrangement as described above, wherein said bolts are slotted bolts.

A tank sealing apparatus as described above, wherein the bottom plate of said double plate is a polyethylene bottom plate.

This is novel has following beneficial effect for prior art: 1) The method firstly solves the problem that the box body sealing test which cannot be implemented when various open pipelines are not closed in a manufacturing plant.

2) Because adopted plugging device to replace, be plectane or rubber buffer structure, can compensate because the local unevenness of face, the not round scheduling problem of pipeline, leak hunting mouth leak hunting is easy, goes wrong good leak hunting.

3) Plugging device is fastener connection, rubber buffer or threaded connection, relies on the sealing washer, fills up sealed pad, and elasticity rubber buffer is sealed, easy dismounting, can accomplish the sealed test of two boxes on average one day, and is efficient, has avoided traditional welding end cap shutoff, inefficiency problem.

4) The large-hole plugging device is processed by the polyethylene hard plastic plate, and is provided with a step spigot matched with the hole during design, so that the weight is light, the cost is low, and the plugging device is convenient for installation and disassembly of installation personnel and saves time and labor.

5) Can be repeatedly used, has high utilization rate and saves cost. And provides experience for the sealing test of other similar sealed chambers.

Detailed Description

The invention will be further elucidated and described with reference to the drawings and the detailed description.

Fig. 1, fig. 2, fig. 3 are according to the position of box trompil, variation in size, the seal structure of three kinds of different grade types of design, and the principle compresses tightly rubber pad, O type circle according to the pretightning force of screw thread, satisfies the demand that compresses tightly, to the less tube hole of diameter, considers the rubber buffer shutoff that adopts vacuum silica gel.
