Problems solved by technology
[0004] The valves in the prior art cannot exhaust the air in the pipeline very well. During the long-distance water delivery process, the pipeline often fluctuates greatly, which is prone to breakage and bridging and water column separation. At the same time, the exhaust gate valves in the prior art are all downtime for maintenance

The invention relates to the field of valves, in particular to an exhaust soft seal gate valve. The exhaust soft seal gate valve comprises a valve, connecting bolts, connecting nuts and a bearing. A valve body is fixedly connected to the middle of the upper end of the valve, a lower mounting seat is fixedly connected to the top end of the valve body, a trace exhaust pipe and a large-quantity exhaust pipe with the bottom ends fixedly connected to the upper end of the valve are arranged on the left side and the right side of the bottom end of the lower mounting seat correspondingly, the top endof the lower mounting seat is fixedly connected with an upper mounting seat through the four sets of connecting bolts and connecting nuts, and a driving cover is fixedly connected to the middle of thetop end of the upper mounting seat. An embedded slot is formed in the middle of the upper end of the valve, a limiting sealing sliding hole is formed in the middle of the valve body, a cooperating groove is formed in the bottom end of the driving cover, the embedded slot, the limiting sealing sliding hole and the cooperating groove are sequentially aligned, a valve rod is in threaded connection with the middle of the driving cover, and a hand wheel is fixedly connected to the top end of the valve rod. The gate valve can well exhaust air in a water conveying pipeline and can be maintained without shutdown.
Description
technical field [0001] The invention relates to the field of valves, in particular to an exhaust soft-sealed gate valve. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to its function, it can be divided into shut-off valve, check valve, regulating valve, etc. The valve is the control component in the fluid delivery system, with the functions of cut-off, regulation, flow diversion, reverse flow prevention, pressure stabilization, diversion or overflow pressure relief, etc. Features. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automatic control systems. There are various types and specifications. Valves can be used to control air, water, steam, various corrosive media, The flow of various types of fluids such as mud, oil, liqui...
