The valve adopts a throttling cage structure, which has the characteristics of strong erosion resistance, easy operation, long service life, removable internal parts, and low maintenance costs.
It is suitable for opening and closing on water, oil, steam and other pipelines. Its typical applications are steam turbine drainage, water supply drainage, heater drainage, boiler drainage, superheater drainage, air drainage, header drain under water wall, and high heating. Hydrophobic.
产品设计制造按国家标准，结构合理、密封可靠、性能优良、造型美观。 1. The product is designed and manufactured according to national standards, with reasonable structure, reliable seal, excellent performance and beautiful appearance.
阀瓣、阀座密封面堆焊 STL 钴基硬质合金耐磨、耐高温、抗擦伤性能好，使用寿命长。 2. The valve disc and valve seat sealing surface are overlaid with STL cobalt-based hard alloy, which is wear-resistant, high-temperature resistant, good abrasion resistance and long service life.
阀门采用卡环式密封结构，密封可靠。 3. The valve adopts a snap ring type sealing structure, which is reliable in sealing.
阀门内件可拆卸，可以在管道无压力下，直接对阀门内件进行拆卸维修 4. The valve internals can be disassembled, and the valve internals can be dismantled and repaired directly under the pressure of the pipeline.
采用节流牢笼式结构，介质经过阀笼时被会降压释放压 能，介质不会正面冲刷密封面，起到防冲刷效果； 5. Adopting a throttling cage structure, the medium will be depressurized to release the pressure energy when passing through the valve cage, and the medium will not flush the sealing surface directly, which will prevent the erosion.
Custody, installation, use and maintenance:
、阀门应存放在比较干燥的室内。 1. The valve should be stored in a relatively dry room.
、长期存放的阀门要定期检查两端的盖板是否完好，清除灰尘及污垢，并在阀门的加工面涂防锈油以防锈蚀。 2. For long-term storage of valves, regularly check whether the covers at both ends are intact, remove dust and dirt, and apply anti-rust oil to the processing surface of the valve to prevent corrosion.
、新管道安装前首先要清洗管道，不准残留焊渣在管道内。 3. Before installing the new pipeline, clean the pipeline first, and do not allow residual welding slag in the pipeline. Check the valve mark to confirm the flow of the medium to determine whether the valve meets the requirements, and then clean the valve to prevent scratching the sealing surface.
、使用压力、温度不能超标，使用介质要正确。 4, pressure, temperature is not exceeded, the media used to correct.
、保证阀杆螺纹良好润滑。 5. Ensure that the valve stem threads are well lubricated.
