Abstract

The stainless steel multifunctional meter front valve comprises a valve body, a valve bonnet and a valve rod, a sealing joint is arranged at the lower end of the valve rod, a mounting bayonet is formed in the lower end of the sealing joint, an elastic sealing valve ring is arranged in the mounting bayonet, a metal valve element is mounted on an inner hole of the elastic sealing valve ring in a matched mode, and the metal valve element is detachably and fixedly connected with the sealing joint. A valve cap is arranged in the valve body, a lever is arranged above the valve cap, an eyelet bolt used for adjusting the distance is arranged between the lever and the valve body, a pressure detection opening is formed in the exposed side wall of the valve cap, a pressure sensor is installed on the pressure detection opening, and a pressure channel communicated with the valve cavity is arranged between the pressure detection opening and the lower end face of the valve cap. The lever is driven to rotate by rotating the swing bolt, the valve rod is driven to ascend and descend, opening and closing of the valve are achieved, the problems that opening and closing of the valve rod are strenuous, abrasion is prone to occurring, and the sealing effect is poor are solved, downstream pressure detection control is achieved, and the pressure reduction proportion of the valve is easy to control.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a stainless steel multi-function front valve. Background technique [0002] The valve in front of the meter is set to facilitate operations such as water cutoff and facilitate maintenance. It can be used as a regulating and shut-off device on fluid pipelines such as tap water, sewage, construction, food, electricity, medicine, metallurgy, textile, and energy. The main types of valves in front of the table are ball valves, gate valves and needle valves. The needle valve is mainly composed of a valve body, a valve core and a valve cap. The valve body is provided with a valve seat, the valve core is conical, the valve core is connected with the valve stem, and the valve stem and the valve cap are threadedly connected. The flow area between the valve core and the valve seat can cut off or adjust the flow of the medium. The sealing between the valve core and the valve seat is achieve...
