Description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Specific embodiment
As shown in figure 1, the implementation case is a kind of upper storage reservoir water-filling and drainage system, the system is arranged in water-storage electricity
Underground workshop spiral case of standing layer unit section, with two sets be connected in parallel fill drainage cell, each fills drainage cell and is filled by one
3, one, water pump (multistage segmental formula centrifugal water pump) slow closed check damper 4, two turbine worm, 6, one, valve of transmission is normally opened manually
Valve 1 and a bypass draining needle-valve 9 are constituted.
In this example, two sets of charging pumps 3 filled in drainage cell are standby each other, also can start simultaneously；Two are filled drainage cell
Charging pump lifting pipe 103 between on Jing storehouse water-filling pump discharge cross over pipe 106 connect, and install on the communicating pipe it is normally closed manually
Valve 7.
The entrance point of charging pump 3 sequentially passes through normally opened hand-operated valve 1, charging pump intake pipe 102, the and of public water supply house steward 105
Public water supply house steward intake pipe 108 is followed by lower storage reservoir tail water discharge；And between the entrance point of charging pump 3 and normally opened hand-operated valve 1
Equipped with low-pressure lateral pressure table 2；Wherein, public water supply house steward 105 is connected to unit inspection and Jing water-carriage systems fill drainage test pipeline 107
Repair drainage system.
The port of export of charging pump 3 sequentially passes through slow closed check damper 4, turbine worm transmission valve 6, charging pump lifting pipe 103
It is connected with upstream pressure steel pipe 13 with after penstock drainpipe 104, the other end of upstream pressure steel pipe 13 and corresponding generating
Unit connects；Wherein, turbine worm transmission valve 6 is provided with two and is connected in series；Slow closed check damper 4 and adjacent turbine worm
Between transmission valve 6, between two neighboring turbine worm transmission valve 6 and between turbine worm transmission valve 6 and normally closed hand-operated valve 7
It is mounted on high side pressure table 5；Generating set is connected by the permanent draining needle-valve 11 of unit with penstock drainpipe 104,
And penstock drainage ball valve 12 is installed on penstock drainpipe 104.
(two are particularly located on pipeline between slow closed check damper 4 and turbine worm transmission valve 6 by arranging a threeway
In the middle of individual turbine worm transmission valve 6) draw charging pump bypass 101 and bypass draining needle-valve 9 and bypass row are installed in the bypass
Water pressure table 10.
The main operational principle and function of the present embodiment is as follows：
1st, meet water-carriage system filling water test and unit starts first the front water-filling of upstream pressure steel pipe 13：First 1# is filled into row
The turbine worm of the normally opened hand-operated valve 1, port of export of the entrance point of charging pump 3 of water unit is driven valve 6 and installed in upper storehouse charging pump
Outlet cross over pipe 106 on normally closed hand-operated valve 7 close, by public water supply house steward's 108 → public water supply of intake pipe house steward 105 →
1# fill the charging pump 102 → 1# of intake pipe of drainage cell (left side of Fig. 1) fill drainage cell charging pump bypass 101 → 1# fill row
Charging pump 103 → penstock of lifting pipe drainpipe 104 of water unit upstream water-filling of penstock 13, and using downstream tail water
Concora crush is carried out to upstream pressure steel pipe 13 and is filled with water to the level of tail water, the time that whole water-carriage system fills drainage test can be shortened；So
Open the normally opened hand-operated valve 1 that 1# fills drainage cell again afterwards, the bypass closed on turbine worm transmission valve 6 and charging pump bypass 101
Draining needle-valve 9, carries out afterwards charging pump 3 and makes pressure startup, and constantly regulate turbine worm is driven the aperture of valve 6, runs charging pump 3
In stability range, while realizing continuous water-filling in upstream penstock 13；Meet water-carriage system filling water test and unit is first
The water-filling of upstream pressure steel pipe 13 is required before secondary startup.
1# fills the limited case in the water filling process of charging pump 3 of drainage cell also dependent on water-carriage system water-filling speed and opens
2# fills the charging pump 3 on drainage cell (right side of Fig. 1), realizes two charging pumps while the upstream water-filling of penstock 13, so as to
Shorten the filling time；In water filling process, can close 1# when the charging pump 3 that 1# fills drainage cell breaks down and fill drainage cell
The turbine worm transmission valve 6 of the port of export of charging pump 3, opens normally closed hand-operated valve 7, and the charging pump 3 that 1# fills drainage cell is isolated into inspection
Repair, using 2# the charging pump 3 of the drainage cell upstream water-filling of penstock 13 is filled, water-carriage system filling water test is ensure that well
With the progress of unit regulation.
2nd, water-carriage system drainage test draining is met：Due to carrying out during water-carriage system drainage test, unit does not have toward contact
Installation, did not possess water condition, it is impossible to carry out the draining of upstream pressure steel pipe 13 by the permanent draining needle-valve 11 of unit.Now
It is accomplished by carrying out draining by charging pump bypass 101, i.e., is filled by upstream pressure steel pipe 13 → penstock, 104 → 1# of drainpipe
Charging pump 103 → the 1# of lifting pipe of drainage cell fills the charging pump of drainage cell and bypasses the charging pump that 101 → 1# fills drainage cell
Intake pipe 102 → public water supply, 105 → water-carriage system of house steward fills drainage test pipeline 107 and is connected to machine set repairing drain system and carries out
Draining.First, closing 1# fills the turbine worm transmission valve of the normally opened hand-operated valve 1, port of export of the entrance point of charging pump 3 of drainage cell
6 and bypass draining needle-valve 9, then it is mounted in concora crush before and after the penstock drainage ball valve 12 on penstock drainpipe 104
After open the ball valve, afterwards small guide vane opens bypass draining needle-valve 9, aperture flow restriction curve according to bypass draining needle-valve 9,
Bypass discharge pressure table 10 shows that pressure and water-carriage system drainage rates require to adjust the aperture of bypass draining needle-valve 9, strict control
Drain discharge processed, it is ensured that the pressure after bypass draining needle-valve 9 is maintained in the range of the safe pressure of pipe-line system permission, due to side
Road draining needle-valve 9 has all carried out strict shop test and inspection, reliable in quality before often dispatching from the factory, conveniently adjust, thus very
The good security reliability that ensure that drainage test.
