Problems solved by technology

[0002] Located on the bottom of the ship, the valve used 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, especially in the coastal waters where shellfish are easy to multiply, because shellfish like to be on the smooth surface However, the ship needs to keep the valve in the open state for a long time, so that the sealing surfaces of the inner cavity of the valve will bite shellfish, causing the valve to be blocked. When the related equipment connected to the valve is overhauled, seawater Leakage into the ship must pass through the valve, which is a problem that ship owners have been worrying about. Therefore, it is of great significance to provide a ship bottom valve that prevents shellfish from the sealing surface

Embodiment Construction

[0008] The present invention will be further described below in conjunction with the accompanying drawings.

[0009] figure 1 As shown, a ship bottom valve of the present invention includes a handle 1, a valve body 2, and a door gate 3. The inner cavity of the valve body 2 below its sealing surface 4 is provided with a pulsator 5, and the shaft lower end of the pulsator 5 Embedded in the bottom wall of the inner cavity of the valve body 2 .

Abstract

The invention discloses a ship bottom valve. The ship bottom valve comprises a handle (1), a valve body (2) and a gate (3); a wave wheel (5) is arranged on an inner cavity below sealing surfaces (4) of the valve body (2). The lower end of a shaft of the wave wheel (5) is embedded in the bottom wall of the inner cavity of the valve body (2). Due to the fact that the wave wheel (5) is arranged on the inner cavity below the sealing surface (4) of the valve body (2), when the gate (3) moves upwards and the valve is in the opening process, horizontal running water pushes the wave wheel (5) to rotate, and seawater in inner cavity of the valve body (2) is stirred by the wave wheel (5), so that implantation of shellfish on all sealing surfaces (4) is difficult, and it is guaranteed that valve closing is smooth and water is not leaked.

Description

technical field [0001] The invention belongs to valves, and more specifically relates to a ship bottom valve. Background technique [0002] Located on the bottom of the ship, the valve used 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, especially in the coastal waters where shellfish are easy to multiply, because shellfish like to be on the smooth surface However, the ship needs to keep the valve in the open state for a long time, so that the sealing surfaces of the inner cavity of the valve will bite shellfish, causing the valve to be blocked. When the related equipment connected to the valve is overhauled, seawater Leakage into the ship must pass through the valve, which is a problem that ship owners have been worrying about. Therefore, it is of great significance to provide a ship bottom valve that prevents shellfish from the sealing surface. Contents of the invention [00...
