Door is a round pontoon valve products, relying on weight and pressure difference inside and outside the door, automatically opening and closing, sealing, anti-return performance, corrosion resistance, ease of installation management.
Round pontoon door for drainage and sewage treatment works to a variety of channels, rivers and shore-return drain outlet for use, can also be used for a variety of shaft covers, it is only for one-way flow of the round shaped outlet.
Round pontoon door specifications:
Equipment nominal pressure (PN) :0.25-1 .6 Mpa; Nominal diameter (DN) :350-2000mm.
Round pontoon door open with forward and reverse flow off the role in the use of doorway pages and doorway pages buoyancy water pressure inside and outside the door errand page on or off.
Round pontoon door advantages:
a, doorway pages for the sealed chamber structure, doorway pages, accounting for 1.05-1.2;
b, the configuration without hanging weight;
c, the door is closed page small impact.
Round pontoon-door installation:
1, door installation with flange connection, can be embedded.
2, the floating box door in the course, you can page through the sealed chamber to the door or turn on the water injection method to change the proportion of doorway pages in order to achieve the best results on.
3, multiple door installation, as a result of lifting conditions need to install a semicolon, should be noted that annotation tags for each door and the door of the portal page to connect with an even, are not interchangeable.
Round pontoon-door Installation Notes:
1, door installation, first check all parts of the bolt is caused due to transport handling loose should be tightened if loose.
2, check the main portal page with links to the door only on whether the water dislocation, dislocation, if you will only loose bolts to adjust the water in the same plane.
3, door installation installation should be used for the whole place to prohibit the portal, doorway pages split installation, to prevent the door leaf deformation.
4, two door before pouring the whole place after looking good before and after lifting, so the correct position, then adjust the bolt with embedded steel weld or flange connection directly with the outlet pipe.
5, door factory, in order to block the door, the door fit tighter page after installation to reduce the gap in the upper and lower horizontal frame door is installed on the pressure iron board, on-site installation of iron removal after the card should be to make door open and close.
6, the pouring of concrete, the flow block the door, doorway pages, inclined railways, baffle gap in the mortar should be removed, to prevent mortar freezing effect opening and closing.
The main submersible pumps are: submersible mixed flow pump, submersible sewage pump, submersible inclined pump, QHB series submersible axial mixed flow pump, WQK series submersible sewage pump, WQD series submersible cutting pump, WLB series vertical sewage pump, GZ series tubular pump , Pump door and control system equipment.
