Valve capable of preventing shellfish-like creatures from biting sealing surface

Abstract

The invention discloses a valve capable of preventing shellfish-like creatures from biting a sealing surface. The valve capable of preventing the shellfish-like creatures from biting the sealing surface comprises a handle (1), a valve body (2), and a gate (3); the valve body (2) is filled with a spongy tubular body (4) capable of tightly holding the gate (3) above the top of the sealing surface and a sponge body (5) with a plurality of through holes in the water flowing direction below the top of the sealing surface; and when the gate (3) is opened, the sponge body (5) closely makes contact with the sealing surface connected with the valve body (2), and the tubular body (4) closely makes contact with the sealing surface connected with the gate (3). The valve capable of preventing the shellfish-like creatures from biting the sealing surface has the characteristics that the shellfish-like creatures cannot adhere to each sealing surface, so that the closing of the valve is smooth, and the sealing surface can be cleaned through the sponge body (5) and the spongy tubular body (4).

Description

technical field [0001] The invention belongs to valves, and more specifically relates to a valve capable of preventing shellfish from gnawing on its sealing surface. 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 valve that can prevent shellfish from stinging...
