Description

A connection device for cargo hold ventilation hatch cover and degassing hose

technical field

The utility model relates to the field of ship accessories, in particular to a connection device of a cargo hold ventilation hatch cover and a degassing hose.

Background technique

In oil and chemical ships, it is necessary to use a degassing fan to purge the cargo hold for degassing operations. The usual method is to extend the other end of the degassing hose connected to the degassing fan into the cargo hold through the small hatch cover. The wind blows into the cargo hold so that the air in the cargo hold can be quickly circulated to a normal oxygen content air environment, and the crew can enter it safely. In this operation, due to the large air volume and wind pressure of the purging fan, the deaeration hose will swing violently in the cargo hold, leak air from the entrance, or even pop out of the cabin frequently. The crew operation generally adopts lashing and other methods to fix it, but it is difficult to Get good results.

Sleeve the annular gland on the upper part of the ventilation hatch cover, the outside of the ventilation hatch cover is hinged with bolts, and the ends of the bolts are screwed with wing nuts, clamp the bolts in the U-shaped opening, and press the wing nuts on the pressure plate. Tighten the connector and the ventilation hatch cover tightly; sleeve the degassing hose on the connecting pipe, the end of the degassing hose is located under the boss, lock the clamp, and use the boss to fix the position of the clamp to prevent The clamps come off the connecting tube, making the connection between the degassing hose and the fitting more secure.

Preferably, the boss is made of round steel. The round steel is used for surrounding welding on the outer wall of the connecting pipe, the process is simple, and the production difficulty is reduced.

Preferably, a round steel is welded around the bottom end of the annular gland. Round steel is welded around the bottom end of the annular gland, which can not only effectively prevent the deformation of the annular gland, but also prevent the edges and corners of the bottom end of the annular gland from scratching the workers, and at the same time improve the aesthetics of the product.

Preferably, the outer edge of the annular gland is provided with a chamfer. The outer edge of the annular gland is provided with chamfers to prevent workers from being scratched by the edges and corners of the annular gland during disassembly and assembly.

Preferably, the clamp is an American-style throat clamp. American-style hose clamps are used, which can be disassembled with a screwdriver, which is easy to operate, has a long service life, and can withstand large pressure requirements.

Compared with the prior art, the utility model has the following advantages:

No need to use tools to connect, use the wing nut that comes with the ventilation hatch to connect and fix it with the pressure plate of the joint, and the operation is simple; The sealing performance is improved, and the air leakage problem between the degassing hose and the ventilation hatch is solved.

Detailed ways

Below in conjunction with the accompanying drawings and the specific embodiments, the specific embodiments of the present utility model will be further clarified. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. After reading the present utility model, Modifications to various equivalent forms of the present invention by those of ordinary skill in the art without creative work all fall within the scope defined by the appended claims of the present application.

As shown in Figures 1 to 3, a connecting device for a cargo hold ventilation hatch cover and a degassing hose includes a joint 2 and a clamp 4. The joint 2 includes a connecting pipe 201, and the bottom end of the connecting pipe 201 is welded with an annular pressure ring. Cover 202, three pressing plates 204 are arranged on the end face of the annular gland 202, the included angle between the adjacent pressing plates 204 is 120°, the outer end of the pressing plates 204 is provided with a U-shaped opening, the outside of the ventilation hatch cover 1 is hinged with bolts 101, and the ends of the bolts 101 are screwed. The wing nut 102 is connected, the bolt 101 is clamped in the U-shaped opening, the wing nut 102 is tightened, and the wing nut 102 is pressed on the pressing plate 204, so that the joint 2 is tightly connected with the ventilation hatch cover 1, and the upper part of the connecting pipe 201 A boss 203 is welded around the outer side.
