Abstract

The invention relates to a stop valve with a double-sealing property. The stop valve with the double-sealing property comprises a valve body, a valve cover, a valve rod and a valve element, wherein the valve cover is detachably connected onto the valve body; the valve rod penetrates through the valve cover to enter the valve body and is rotatably connected with the valve cover; the valve element is connected to the bottom part of the valve rod; a flowing port is formed in the valve body; a liquid inlet hole is formed in the left side of the flowing port; a liquid outlet hole is formed in the right side of the flowing port; a movable baffle plate is arranged on the upper side in the liquid outlet; a driving gear coaxially rotated with the valve rod is arranged on the valve rod above the valve element, and drives the movable baffle plate to move up and down through a transmission mechanism; and through the up-and-down movement of the movable baffle plate, the liquid outlet can be openedand closed. According to the stop valve with the double-sealing property provided by the invention, through the valve element and the movable baffle plate, a double-stopping function of the stop valveis realized at the same time, so that the stopping function of the stop valve is improved, the service life of the stop valve is prolonged, and the working efficiency is improved since the valve element has no need to be frequently replaced.

Description

technical field [0001] The invention relates to the field of stop valves, in particular to a stop valve with double sealing properties. Background technique [0002] The globe valve, also known as the gate valve, is a forced sealing valve. It is durable, has a small opening height, is easy to manufacture, and is easy to maintain. It is not only suitable for medium and low pressures, but also for high pressures. The closing principle of the globe valve is to rely on the pressure of the valve stem to make the sealing surface of the valve core and the sealing surface of the valve body flow port tightly fit to prevent the medium from flowing. [0003] When the traditional stop valve is in use, when the valve core is worn due to the erosion of the fluid medium, the valve core will not be able to block the flow port, resulting in leakage, which requires frequent manual replacement of the new valve core , resulting in reduced work efficiency. Contents of the invention [0004] ...
