Abstract
The utility model discloses a simple segmented hydrostatic pressure test waster source converting device which comprises a converting pipe and a blocking plate. The middle part of the inner diameter of the converting pipe is fixedly connected with the blocking plate. The converting pipe is divided into two parts by the blocking plate, namely a first converting pipe part and a second converting pipe part; a first opening is formed at the upper part of the first converting pipe; a first brake valve is fixedly arranged at the first opening. A second opening is formed at the upper part of the second converting pipe; a second brake valve is fixedly arranged at the second opening. An immersible pump is arranged inside the first converting pipe and is connected with a drainage pipe; the drainage pipe passes through the first opening and the second opening; the other end of the drainage pipe is placed inside the second converting pipe. The device is simple in structure, and repeated use of test water can be achieved, so that water is greatly saved; the device is simple and convenient, eliminates trouble of draining water and dredging, and is particularly used for a segmented hydrostatic pressure test of a large water conveyance project PCCP (Prestressed Concrete Cylinder Pipe) with large diameter and long distance.
Description
Technical field
The utility model belongs to water test unit field, particularly relate to heavy caliber, long distance large-scale water delivery engineering hydrostatic test water source conversion easy device, while carrying out segmentation hydrostatic test for the PCCP pipeline of large-scale water delivery engineering heavy caliber (DN3200-3800), long distance, use during the recycling of water.
background technology
Pipeline segmentation hydrostatic test is comprehensive inspection of interface to pipeline, pipe workpiece quality, construction and installation quality.Generally, because the interior hydraulic pressure of large-scale water delivery engineering pipeline is high, when pipeline length, hydrostatic test completely, need to inject the reason of large water gaging, before pipeline segmentation hydrostatic test, to carry out water source under different terrain geomorphologic conditions and draw the scheme such as connect, draining is dredged, the hydraulic testing requires test water clean, forbids to adopt pollution or harmful water source to carry out the hydraulic testing.Hydrostatic test has completely been difficult to.
After large-scale water delivery engineering heavy caliber, long distance P CCP tubing are installed 1 kilometer continuously, must carry out first section of hydrostatic test.After the first section of hydraulic testing is qualified, with installation progress utilization, suppresses pipe and carry out piecemeal hydrostatic test.Segmentation hydrostatic test length should not surpass 10 kilometers, and concrete section length should be determined according to actual landform situation.The PCCP tubing of DN3600 of take is example, and 1 kilometer of pipeline hydraulic testing needs more than 10000 cubic metre, water.Therefore, in large-scale water delivery engineering segmentation hydrostatic test, the recycling of water is extremely important.
Utility model content
The utility model is the problem that a large amount of clean water are difficult to recycling during for large-scale water delivery engineering segmentation hydrostatic test, the segmentation hydrostatic test water source conversion easy device proposing, this device can make test water recycling, and has saved great lot of water resources, and method is easy.
The technical scheme adopting is:
Segmentation hydrostatic test water source conversion easy device, comprises crossover connection and closure plate.
Its technical essential is:
Closure plate has been fixedly connected in the middle part of crossover connection internal diameter.
Closure plate is divided into two parts by crossover connection, and two parts are respectively the first crossover connection and the second crossover connection.
The first crossover connection top is provided with the first opening, and the first opening part is fixedly equiped with the first gate valve.
The second crossover connection top is provided with the second opening, and the second opening part is fixedly equiped with the second gate valve.
In the first crossover connection, be provided with submersible pump, submersible pump is connected with drainpipe, and drainpipe is by the first opening and the second opening, and the other end of drainpipe is positioned at the second crossover connection.
Crossover connection is pipe.Closure plate is circular slab.
The first opening and the second opening size radius are 0.5 meter～0.8 meter.
The first gate valve and the second gate valve are DN80～DN100.
Its using method is:
Before pipeline segmentation hydrostatic test, easy device port is changed in water source and PCCP mouth of pipe size matches, connect with PCCP pipeline I section, II section respectively.
While carrying out segmentation hydrostatic test first, PCCP pipeline I section is full of to water, after hydrostatic test is qualified, by the first opening, submersible pump is inserted to PCCP pipeline I section, submersible pump drainpipe is inserted PCCP pipeline II section by the second gate valve of the second opening, utilize submersible pump that PCCP pipeline I section test water is entered to PCCP pipeline II section, and supplement after a little not enough water yield, carry out the hydrostatic test of PCCP pipeline II section, after stand the test, submersible pump is taken out from PCCP pipeline I section by the first opening, put into the water source of next segmented pipeline and change simple and easy dress, repeat above-mentioned work.Staff enters in pipe by the first opening, with gas welding cutting, takes out the closure plate of easy device, welding shutoff the first opening, the second opening.By that analogy, complete the segmentation hydrostatic test of whole pipeline.
Its advantage is:
This apparatus structure is simple, can accomplish test water recycling, has saved great lot of water resources, and method is easy, has removed the trouble that draining is dredged from.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
