Description
Technical field
The present invention relates to drinking water pipeline system regions, more particularly to a kind of big flow PP-R pipe-line systems.
Background technology
PP-R pipelines are as the higher product of cost performance, it has also become horizontal branch pipe field hot and cold water feedwater piping system in building
System main product.PP-R pipelines mainly use hot-melt adhesive paste, realize that water route turns to 90 ° of elbows, pipeline point is realized with positive threeway
Branch turns to, and realizes that hot and cold water intersects intercommunication with bridge elbow, using shut-off valve or ball valve as master switch, PP-R pipelines and several accessories
Welding forms hot and cold water pipeline system in series.90 ° of elbows, positive threeway, bridge elbow accessory are during water delivery, head
It hits, reflux, head loss is high, and cut-off valve fitment is the design of half flux, and flow weakens big.
Common PP-R pipelines are generally dumb light type, and for surface roughness at 0.1-0.3 μm, hydrodynamic contant still has room for promotion.
Pipe-line system universality environment is pressure of supply water 0.3MPa or more, with being not more than 5 between water, disclosure satisfy that water demand, has
Preferably use water comfort.But as living standard is continuously improved, big flat bed, foreign-style house and villa customers increase, between water, use
Water spot is significantly increased, respectively with water spot simultaneously with often occurring water decrease when water, or even phenomenon of cutting off the water supply, make traditional PP-R pipelines
System, which can not provide, preferably uses water comfort level；Meanwhile high-rise the commercial house continues to bring out, and although there is multistage pressuring machine, high-rise water
Pressure is insufficient, and problem exists always, also results in the reduction with water comfort level.The pipe design mode of tandem, the water when pipeline extends
Power loses bigger, and there is also the maintenance drawbacks of " some leaks, full room cut off the water ".
Invention content
The invention is intended to provide one kind to improve water flux density, and the works such as too small, the multiple spot water of pressure of supply water can be met
A kind of big flow PP-R pipe-line systems that condition water requires.
A kind of big flow PP-R pipe-line systems in this programme, including water main and several branch pipes, several branch pipes and master
Water pipe is connected to, and gate valve is equipped on water main, elbow, water main, Ruo Gangen are both provided on water main and several branch pipes
The material of branch pipe, gate valve body and elbow is PP-R materials, the water main of PP-R materials, several branch pipes, gate valve body and
Elbow interior wall roughness value is between 0.05-0.1 μm.
The technical principle of this programme is：Shut-off valve is substituted as system master switch or branch switch using gate valve, improves water
Circulation；Water main, several branch pipes, gate valve body and elbow are using PP-R materials, in the pipeline that PP-R materials are fabricated to
The smooth non-scaling of wall, more reduces the resistance to water, to further increase flow；The water main of PP-R materials, several branch pipes,
Gate valve body and elbow interior wall roughness value are reduced between 0.05-0.1 μm, further reduce the resistance to water, to
Further improve flow.
Compared with prior art, this programme has the beneficial effect that：This programme, and will above each component by the replacement of valve
Material be substituted for PP-R materials, the inner wall roughness coefficient of the finished product that PP-R materials are fabricated to be reduced to 0.05-0.1 μm it
Between, when water flows wherein, the resistance to water can be reduced well, to greatly improve the circulation of water, the circulation of water
20%-25% can be promoted.
Further, the specification of water main and branch pipe is dn20-dn32.Under the pressure condition for ensureing water, water also can guarantee
Circulation.
Further, elbow includes communicating pipe, and the inlet and outlet of communicating pipe are communicated with short tube, communicating pipe center circular arc line song
The ratio between rate radius and the radius of bore in communicating pipe are (5~6)：1.With the elbow of this radius of curvature with respect to 90 degree of elbow bends,
The resistance to water is reduced, head loss is also reduced.
Further, down stream tee joint is communicated on water main, branch pipe is two, and two branch pipe connections are on down stream tee joint.With
Down stream tee joint substitutes positive threeway, reduces head loss.
Further, the material of down stream tee joint is PP-R materials, and the down stream tee joint inner wall roughness coefficient of PP-R materials also exists
Between 0.05-0.1 μm.Resistance of the down stream tee joint to water is further reduced, the flow of water is improved.
Further, down stream tee joint includes straight tube and bend pipe, and bend pipe is connected in the side of straight tube, the song of bend pipe center circular arc line
The ratio between rate radius and the radius of bore in bend pipe are (5~6)：1, the internal channel diameter of bend pipe and the internal channel diameter phase of straight tube
Deng.With the relatively positive threeway of the down stream tee joint of this radius of curvature, the resistance to water is not only reduced, head loss is also reduced, is carried
The high flow of water.
Further, water knockout drum is communicated on water main, several branch pipes are connected on water knockout drum.The setting of water knockout drum,
Realize that parallel connection type supplies water, waterpower is more uniform, and maintenance is convenient.
