Description

Technical Field

[0001] The utility model relates to the technical field of valve equipment, in particular to a high-sealing valve. Background Art

[0002] A valve is a device used to control the direction, pressure, and flow of a fluid in a fluid system. It is a device that allows the medium (liquid, gas, powder) in pipes and equipment to flow or stop and control its flow. A valve is a control component in a pipeline fluid delivery system, used to change the passage section and the flow direction of the medium, and has functions such as diversion, cutoff, throttling, non-return, diversion, or overflow pressure relief.

[0003] The existing valve structure usually sets a group of valve structures to realize the overall switch. Since the valve is immersed in liquid for a long time, long-term use will cause the control structure of the valve to rust, which will lead to reduced valve sealing. Here we propose a high-sealing valve that can set multiple groups of valves to work at the same time, improve the sealing of the equipment, and thus increase the service life of the equipment.

[0012] 1. The utility model uses a rotating wheel, a rotating rod, an upper bevel gear, a lower bevel gear, a middle rotating shaft, a power gear, a gear belt, a driven gear, a side rotating shaft, a stop valve, a ball valve, and a water outlet in coordination. By rotating the rotating wheel, the rotating rod drives the upper bevel gear to rotate, and the middle rotating shaft is driven to rotate through the lower bevel gear.
