产品介绍

一、进口内螺纹升降式止回阀概述

进口内螺纹升降式止回阀的结构一般与截止阀相似，其阀瓣沿着通道中以线作升降运动，动作可靠，但流体阻力较大，适用于轻小口径的场合。内螺纹升降式止回阀一般只能安装在水平管路。

The structure of the internal thread lifting check valve is generally similar to that of a globe valve. The valve disc moves up and down along a line in the channel, with reliable action, but with high fluid resistance, making it sui for situations with light and small diameters. Internal thread lifting check valves can generally only be installed in horizontal pipelines.

二、进口内螺纹升降式止回阀产品特点

1、结构简单、体积小、重量轻

2、多种螺纹类型：G•NPT.BSPT.BSP DIN259/2999可供选择

3、流道通畅、流体阻力小，阀瓣在很小的压差下就能完全打开

4、维修方便，球阀结构简单，密封圈一般都是活动的，拆卸更换都比较方便

5、硅溶胶精密铸造不诱钢阀体、阀盖

6、于水、油、气及某些腐蚀性气体介质

7、额定工作压力为1000PS1（7.0）Mpa0）

1. Simple structure, small size, and light weight

2. Multiple thread types: G • NPT BSPT.BSP DIN259/2999 available for ion

3. The flow channel is unobstructed, the fluid resistance is small, and the valve disc can be fully opened at a very small pressure difference

4. Convenient maintenance, simple ball valve structure, and generally movable sealing rings make disassembly and replacement more convenient

5. Silica sol precision casting for stainless steel valve bodies and covers

6. In water, oil, gas, and certain corrosive gas media

7. Rated working pressure is 1000PS1 (7.0) Mpa0)
