The multifunctional combined valve has the functions of cutting off, filtering, checking and remote intelligent control. It integrates multiple functions. Its perfect combination structure is compact, which saves installation space and raw materials. The product runs reliably and has the advantages of online operation, quick and convenient removal of filter and small water loss. It has both the excellent function of filtering and the function of cutting before and after itself.
Cutting part : the opening and closing of the medium is controlled by the butterfly valve, the operation is simple and the torque is small.
Filtration part : multi-row U-shaped filter effectively filters the impurities in the medium and removes the dirt in the fluid medium. The butterfly valve opens, the filtration system enters the running state, and the butterfly valve closes the filter chamber automatically before and after closing. It can open the valve cover of the filter chamber and the screw plug or valve at the bottom of the valve, remove the filter screen for cleaning, and clean the dirt in the filter chamber.
The check part : open by the pressure of the medium downstream to overcome the torsion of the spring, and seal by the torque generated by the spring and the sealing specific pressure generated by the pressure of the medium upstream to prevent the medium backflow, thus effectively preventing the occurrence of water hammer phenomenon.
Remote intelligent control part : when needed in the field operation system, the medium pressure, temperature and other data in the system can be carried out according to the working condition system. The driving device is electric, which can remotely operate the opening and closing and adjust the opening Angle, and can also be timed switch.
1. Multi-functional combination valve set butterfly valve, filter and check valve in one, easy to install, save raw materials and use space.
2. Multi-functional combination valve butterfly valve part: simple and compact structure, small and lightweight, 90 degrees open and close, quick switch. Easy to operate and light.
3.Multifunctional combination valve filter part : it is used to filter impurities in the medium, and the filter part uses U-shaped multi-row structure design, with small resistance and convenient sewage discharge. There is a sewage hole at the bottom of the valve. When the sewage is discharged, the butterfly valve is closed, and the check valve is automatically closed. At this time, the valve cover of the filter part and the screw plug or valve of the sewage hole at the bottom of the valve are opened, The filter screen and dirt can be easily discharged, Then the filter part is rinsed, and the filter mesh is put in after cleaning, and the valve cover and the sewage plug at the bottom of the valve are installed and tightened. This process can also monitor whether the check part and the cut part leak.
4.Design of multi-function combination valve check part: with quiet, slow impact, prevent backflow, fast closing characteristics. The spring intercepts on the disc to shorten the closing stroke, providing a rapid response to flow changes, effectively preventing water hammer phenomenon and impact noise, full flow area effectively reducing pressure loss.
5.Multifunctional combination valve intelligent remote control system: the valve body is equipped with a number of sensor interfaces, different sensors connected to the valve body can monitor different data, such as monitoring medium pressure, temperature, etc. Effectively control the performance indicators of the pipeline system, and alarm in time beyond the set range.
6. Multifunctional combination valve can be installed in vertical or horizontal pipeline, customers can choose the driving mode according to the working condition, driving mode: manual, pneumatic, electric, etc.
7.The multifunctional combined valve adopts epoxy electrostatic spraying, which has beautiful appearance and can effectively prevent corrosion. The valve body coating and rubber seal material is with WRAS Certificate for drinking water.
8.Multifunctional combination valve can use different materials according to the working conditions of the medium and other factors, to meet the requirements of working conditions and medium.
Multifunctional combination valve is widely used in water supply and drainage, building control, central air conditioning, seawater desalination, heating and other pipeline system fluid cut-off, open, medium filtration, backflow prevention, as well as remote monitoring media pressure, temperature, etc.
