一、进口螺纹带焊接管球阀概述

进口螺纹带焊接管球阀（美国威盾VTON），Threaded pipe with welded ball valve，也叫液压阀 液压球阀 高压球阀 外螺纹带焊接管高压球阀,焊接式高压球阀,外螺纹焊接高压球阀 板式高压球阀 不锈钢高压球阀 天然气高压球阀。

是指采用外螺纹连接，并带活接焊接管的球阀，安装方便。具有体积小、抗震动的特点。是由三部分阀壳组成，由四只较长螺栓从两端夹住中间阀体与阀球而成。其优点是维修拆卸时不用拆卸管路螺纹，而直接拆卸四只螺栓，阀体中间部分既可取出。适用于液压系统管路中，作接通和切断用，主阀采用优质锻钢件，表面进行镀铬处理，外表美观，操作方便，密封性能可靠。

Thread pipe with welded ball valve, also known as hydraulic valve, hydraulic ball valve, high-pressure ball valve, external thread with welded pipe high-pressure ball valve, welded high-pressure ball valve, external thread welded high-pressure ball valve, plate type high-pressure ball valve, stainless steel high-pressure ball valve, natural gas high-pressure ball valve

It refers to a ball valve that is connected with external threads and comes with a union welded pipe, which is easy to install. It has the characteristics of small volume and anti vibration. It is composed of three parts of valve casing, consisting of four longer bolts clamping the middle valve body and valve ball from both ends. Its advantage is that during maintenance and disassembly, there is no need to dismantle the pipeline threads, and the four bolts can be directly removed. The middle part of the valve body can be taken out. Suitable for connecting and cutting hydraulic system pipelines, the main valve is made of high-quality forged steel parts with chrome plating treatment on the surface, which has a beautiful appearance, convenient operation, and reliable sealing performance.
