Abstract

The invention discloses a novel gate valve. The novel gate valve is simple in structure, convenient to open and long in service life. The novel gate valve comprises a gate valve body, a valve deck arranged above the gate valve body, a water inlet channel and a water outlet channel, wherein the water inlet channel and the water outlet channel are formed in the radial direction of the gate valve body, a valve rod is arranged in the gate valve body, a first channel is formed in the gate valve body, the upper end of the valve rod penetrates out of the first channel, the gate valve body is located in the first channel and fixedly provided with a sealing plate used for separating the first channel, the water inlet channel communicates with the lower end of the first channel, the gate valve body is provided with a second channel, the second channel communicates with the water outlet channel, a water passing channel connected with the first channel and the second channel is formed in the gate valve body, a sealing ball used for sealing and opening the second channel is arranged in the second channel, and an opening and closing device used for controlling the sealing ball to be opened and closed is arranged in the gate valve body.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a novel gate valve. Background technique [0002] With the development of the pipeline industry, gate valves are more and more widely used in pipeline connections. The gate valve is an opening and closing gate, and the direction of movement of the gate is perpendicular to the direction of the fluid, so as to achieve the purpose of opening and closing the gate valve. The traditional gate valve, when the traditional gate valve is opened and closed, is connected by the thread of the valve stem and the valve body. Although this can meet the demand, the threaded connection between the valve stem and the valve body is not only laborious and labor-intensive when opening or closing, but also prone to jamming or thread slippage after long-term use, making it difficult for the staff to turn the valve stem to open the valve. closure. Contents of the invention [0003] Therefore, aiming ...
