Abstract

The invention provides a marine mechanical valve with high sealing performance. The marine mechanical valve comprises a sealing plate, ejector rods, L-shaped gas guiding pipelines, a sleeve, a pistonplate and a connecting rod, wherein the connecting rod is fixed to the lower end of a valve plate; the lower end of the connecting rod extends from the lower end of a valve cavity to be rotatably connected with the upper end of the piston plate through bearings; the piston plate is located inside the sleeve; the sleeve is fixed to the lower end surface of the valve cavity; the L-shaped gas guidingpipelines are fixedly connected to the lower left side and the lower right side of the sleeve; the upper ends of the L-shaped gas guiding pipelines are slidably connected with the ejector rods; the ejector rods are fixed to the lower end surface of the sealing plate; the connecting rod is sleeved with the sealing plate; the sealing plate is located directly under the valve plate; and both the sealing plate and the ejector rods are arranged inside the valve cavity. In this way, the purpose of re-blocking is achieved, so that the sealing effect is improved, the function of secondary leakage prevention is achieved, and the leakage prevention effect is improved.

Description

technical field [0001] The invention is a marine mechanical valve with strong sealing performance, which belongs to the field of marine valves. Background technique [0002] When the existing marine mechanical valves are used, they usually only have a single-layer sealing function, the sealing effect is poor, and the valve is easy to leak. Therefore, a marine mechanical valve with strong sealing performance is needed to solve the above problems. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a marine mechanical valve with strong sealing performance to solve the problems raised in the above-mentioned background technology. High, good leak-proof effect. [0004] In order to achieve the above object, the present invention is achieved through the following technical solutions: a marine mechanical valve with strong sealing performance, including a valve stem, a valve cover and a valve cavity, ...
