一、进口螺纹高压单向阀概述

进口螺纹高压单向阀，是指采用不锈钢或者碳钢材质，采用整体锻造，弹簧作用，耐高压的单向阀，靠管路中介质本身的流动产生的力而自动开启和关闭的，属于一种自动阀门。单向阀用于管路系统，其主要作用是防止介质倒流、防止泵及其驱动电机机反转，以及容器内介质的泄放。焊接式单向阀只允许介质向一个方向流动，而且阻止方向流动。

A threaded high-pressure one-way valve refers to a one-way valve made of stainless steel or carbon steel material, forged as a whole, with spring action, and resistant to high pressure. It automatically opens and closes by the force generated by the flow of the medium in the pipeline. It belongs to an automatic valve. A one-way valve is used in pipeline systems, and its main function is to prevent medium backflow, prevent the pump and its driving motor from reversing, and discharge the medium inside the container. Welding type one-way valve only allows medium to flow in one direction and prevents flow in that direction.

VTON high-pressure one-way valves from the United States include one-way valves, sleeve one-way valves, welded one-way valves, threaded one-way valves, high-pressure one-way valves, hydraulic one-way valves, instrument one-way valves, and stainless steel one-way valves
