Abstract

The invention provides a self-closed deck plane valve. The self-closed deck plane valve comprises a valve body, a spring and a sealing gasket; the valve body comprises a valve rod, a valve seat and aspring base; the sealing gasket is arranged on the surface of the valve rod; the spring base is arranged on the valve rod in a sleeving mode and fixedly connected to the valve seat; the spring is arranged on the valve rod in a sleeving mode, one end of the spring abuts against the end face of the spring base, the other end of the spring is fixedly arranged on the outer circumference of the valve rod, and the spring is in a compressed state; the valve rod moves between an opening position and a closing position; when the valve rod is located at the opening position, the valve seat is separatedfrom the valve rod; and when the valve rod is located at the closing position, the valve seat and the valve rod are buckled, and the sealing gasket abuts against the valve seat. According to the self-closed deck plane valve, the structure is simple, operation is convenient, and self-closing of the valve can be achieved.

Description

technical field [0001] The invention relates to a plane valve, in particular to a self-closing deck plane valve. Background technique [0002] At present, there will be accumulated water in the sewage well of the service channel of the container ship, which needs to be discharged to the side or the cargo hold sewage well through the deck plane valve. The deck level valve is usually closed, and the deck level valve is artificially opened when the accumulated water needs to be discharged. However, the operation of opening and closing the deck plane valve in the prior art is complicated, and cannot realize self-closing. Once the user forgets to close the plane valve after emptying the accumulated water, there is a potential safety hazard. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a self-closing deck plane valve in order to overcome the defects of the prior art. [0004] The present invention solves the above...
