概述 I. Overview of water bottom valve
   The SSDF-1 water bottom valve is a replacement product of the water bottom valve. When it is used as a bottom valve, it can be installed at the turn of the riser when the inlet pipe is exposed on the water. When used as a check valve, it can be installed at the 90 turn of the pump instead of the elbow. The background valve has low frictional resistance, simple installation, convenient maintenance, and can be installed and repaired on water. Its sealing performance is good, and it can prevent water from leaking. Water bottom valve is mainly suitable for supporting the use of pumps in petroleum, chemical, textile, drainage and irrigation industries. Can be used in front of the pump instead of the foot valve. Can be used after pump instead of check valve.

使用说明 Instructions for use of water bottom valve
、规格: DN50 DN65 DN80 DN100 DN125 DN150 DN200 DN250 DN300 DN400 DN500 DN600 DN700 DN800 等规格。 1. Specifications: DN50 , DN65 , DN80 , DN100 , DN125 , DN150 , DN200 , DN250 , DN300 , DN400 , DN500 , DN600 , DN700 , DN800 and other specifications.
、公称压力: 0.6MPa 2. Nominal pressure: 0.6MPa
、安装要求:安装在水泵吸水管的垂直管与水平管的转弯处,安装时应保证其垂直状态。 3. Installation requirements: Install at the turning point of the vertical pipe and horizontal pipe of the pump suction pipe, and ensure the vertical state during installation.
、启动:首次启动前向水平管中充满水之后迅即启动,造成吸水管内半真空状态,将水吸入竖直管,以完成泵水过程。 4. Start-up: After the water is filled in the horizontal pipe before starting for the first time, it starts immediately, causing a semi-vacuum state in the suction pipe, and sucking water into the vertical pipe to complete the pumping process. When the suction stroke is too large, it is necessary to repeat the water-filling start several times, and then stop the pump, and it is not necessary to fill the water before starting the pump.
、检修:一般情况下使用不必检修。 5. Overhaul: Under normal circumstances, there is no need to overhaul. When maintenance is needed, just open the bonnet above the water bottom valve and replace the rubber pad. After the maintenance, the pump is started for the first time.
、如使用在酸碱浓度较高的流体中,请您选用不锈钢材质的水上式底阀,同时我厂可根据用户要求生产全塑料水上式底阀或 316L (钼尔钛)材质的水上式底阀。 6. For use in fluids with high acid-base concentration, please choose stainless steel water bottom valve. At the same time, our factory can produce all plastic water bottom valve or 316L (molybdenum titanium) material Foot valve.
