For achieving the above object, the utility model provides following technical scheme:
A coefficient of permeability testing tool for water-permeable brick, comprise shell, fixed support, water inlet, dividing potential drop de-bubble plate, freeing port, sample chamber, set bolt and water delivering orifice, described shell is fixed on fixed support; Described water inlet is located at cover top portion, is provided with dividing potential drop de-bubble plate below water inlet; Described dividing potential drop de-bubble plate is provided with equally distributed aperture; Described freeing port is located at the below of dividing potential drop de-bubble plate; Described sample chamber is located between freeing port and water delivering orifice, and this sample chamber is connected with shell by draw-in groove, and top, sample chamber is connected with shell by set bolt; Described water delivering orifice is located at outer casing bottom.
The vertical range of described sample chamber and freeing port is 40-55cm.Ensure that this vertical range can make the sample of sample chamber bear certain pressure, to ensure that the continuous and effective of sample is permeable, draining.
As further scheme of the present utility model: described housing integration is hollow square shape structure, and adopt transparent material to make, conveniently can observe the concrete condition in shell.
For avoiding the water of water inlet directly to drop down onto sample chamber, make the sample contacts hydraulic pressure of sample chamber uneven, thus cause sample test error, the water of water inlet can be carried out shunting dividing potential drop by dividing potential drop de-bubble plate, thus avoids the test error of sample.
As further scheme of the present utility model: described dividing potential drop de-bubble plate has two-layer up and down, the aperture on two-layer dividing potential drop de-bubble plate is not overlapping in vertical direction.
As further scheme of the present utility model: the installation place of described sample chamber and shell is provided with rubber washer.This rubber washer plays sample chamber and body seal is installed, thus avoids drainage to occur.
As further scheme of the present utility model: described sample chamber is can from disassembling shell independently sample chamber out.
As further scheme of the present utility model: be placed with sample in described sample chamber, sample lies against in sample chamber, and the gap between sample and sample chamber has hermetically-sealed construction.Sealing structure is rubber cement or the fluid sealant structure of coating.
Compared with prior art, the beneficial effects of the utility model are: the coefficient of permeability testing tool of this water-permeable brick, the sample contacts area large (being almost monoblock water-permeable brick face) of permeable test, and coefficient of permeability test is efficient, accurate, simple, convenient; Whole dress sample flow process, only needs two minutes, than similar technique, speed at least improves 50 times; Adopt sample chamber dress sample, sample is monoblock water-permeable brick, so and n.s. processed finished products rate problem.
The coefficient of permeability testing tool of the water-permeable brick that the utility model provides, structure is simple, easy to install, and coefficient of permeability test is efficient, accurate, by changing the size of sample chamber and shape, the coefficient of permeability that just can be widely used in the water-permeable brick of dissimilar and shape is tested.
