Problems solved by technology

[0002] Located on the bottom of the ship, the valve for the cooling system of the turbine is connected to the sea at its water inlet. Since the ship has been immersed in the sea for a long time, and the valve needs to be kept open for a long time, the inner cavity of the valve, especially the seals It will bite shellfish on the surface, which will cause the valve to be blocked. When repairing the related equipment connected to the valve, seawater will leak into the ship through the valve. This is a problem that has always worried ship owners. Therefore, a The valve of anti-shellfish biological sting cloth is of great significance

Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings.

[0011] figure 1 As shown, a valve for preventing shellfish biological stinging cloth includes a handle 1, a valve stem 2, a valve body 3, and a door gate 4. The valve stem 2 has a cavity with an open bottom at the lower part of the handle 1, The cavity is filled with shredded tobacco 5 .

[0012] In order to improve the effect of expelling shellfish and the persistence of slow-release nicotine, nicotine, tar and other substances, the shredded tobacco 5 is preferably made of fresh tobacco leaves, and fresh tobacco leaves do not need to be dried after picking Shredded to a size equivalent to the shredded tobacco in a cigarette, it can be firmly filled in the cavity. In a ship landing overhaul period, generally 6-9 months, the valve of the present invention will not be blocked due to shellfish stings on the sealing surfaces.

Abstract

The invention discloses a valve preventing biting and distribution of shellfish. The valve comprises a handle (1), a valve rod (2), a valve body (3) and a gate (4). The valve rod (2) is provided with a cavity on the lower portion of the handle (1), and the bottom face of the cavity is open. The cavity is filled with cut tobacco (5). The cut tobacco (5) arranged in the cavity of the valve rod (2) continuously and slowly releases nicotine, nicotinamide, tar and other substances hated by the shellfish, the shellfish is urged to leave as soon as possible and is prevented from staying in the inner cavity of the valve rod (2), implantation, biting and distribution of the shellfish on all seal faces are especially prevented, and thus valve closing is smooth.

Description

technical field [0001] The invention belongs to valves, and more specifically relates to a valve for preventing shellfish biological bites. Background technique [0002] Located on the bottom of the ship, the valve for the cooling system of the turbine is connected to the sea at its water inlet. Since the ship has been immersed in the sea for a long time, and the valve needs to be kept open for a long time, the inner cavity of the valve, especially the seals It will bite shellfish on the surface, which will cause the valve to be blocked. When repairing the related equipment connected to the valve, seawater will leak into the ship through the valve. This is a problem that has always worried ship owners. Therefore, a kind of The valve of anti-shellfish biological bite cloth has very important significance. Contents of the invention [0003] The object of the present invention is to provide a valve for preventing shellfish biological stings. [0004] The valve of the presen...
