The utility model content
The purpose of this utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of simple in structure, installation and maintenance convenient, cost is low, the liquid metering device of quantification stability.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of liquid metering device, be connected on the storage tank, this device comprises bumper post chamber, liquid level post, connecting pipe and scaleplate, described bumper post chamber is connected to the lower end of storage tank, described liquid level post vertically arranges, be connected by connecting pipe between described liquid level post and the bumper post chamber, described scaleplate and liquid level post be arranged in parallel.
Described bumper post chamber comprises glass visor and bumper post, and the upper end of described glass visor is connected to the lower end of storage tank by flanged connecting pipe, be tightly connected between the lower end of glass visor and the bumper post.
Connecting pipe between described glass visor and the storage tank is provided with valve.
Described liquid level post is that internal diameter is the glass tube of 1cm, and the height of described liquid level post is more than or equal to the height of storage tank.
The caliber of described connecting pipe is identical with the liquid level post, and the corner of connecting pipe is the arc of rounding off.
Described scaleplate is wooden boards, and length and thickness can be selected voluntarily according to measuring needs, and general painted white is with protection sheet material and sign scale.
Be connected by rubber tube between liquid level post and the connecting pipe.
When using device of the present utility model, at first open valve, fill with bumper post chamber and liquid level post with clean water, when the liquid in the bumper post chamber just contacts exit, storage tank lower end, the height of liquid is labeled as zero point by scaleplate in the liquid level post, and the liquid in the expression storage tank is zero.After adding liquid in the storage tank, because the pressure of liquid, liquid in the storage tank will make hydraulic pressure in the bumper post chamber to connecting pipe and liquid level post, the interior liquid levels height of the last so that water colunm height in the liquid level post and storage tank is identical, can learn the height of liquid in the storage tank by the liquid level post height that identifies on the scaleplate.
After device is installed, in the following ways scaleplate is indicated scale:
According to the size of storage tank, namely the radius of the xsect of storage tank or storage tank with reference to the density of liquid in the storage tank, adds water-immiscible liquid again in storage tank, according to formula:
G
Liquid=π R
2ρ
Liquidh
Water/ 1000
Wherein, G
Liquid: the amount of liquid kg that adds in the storage tank;
R: storage tank radius, cm;
P
Liquid: the density of liquid in the storage tank, g/cm
3
h
Water: the height of water column on the scaleplate, cm;
The density of the radius of the quality of liquid, storage tank, the interior liquid of storage tank can be calculated the height of liquid in the storage tank in the known adding storage tank, and the height of liquid is identical with the height of liquid level post in the storage tank, and the height that calculates is indicated on the scaleplate.
In the metering storage tank, during liquid, open valve, the liquid in the storage tank with the hydraulic pressure in the bumper post chamber to the liquid level post, by the liquid reserves in the position display storage tank of liquid level in the liquid level post.
Compared with prior art, the utility model is simple in structure, installation and maintenance are convenient, cost is low, quantification stability, applied widely.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1 is storage tank, and 2 is valve, and 3 is the glass visor, and 4 is bumper post, and 5 is connecting pipe, and 6 is scaleplate, and 7 is the liquid level post.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of liquid metering device, as shown in Figure 1, be connected on the storage tank 1, this device comprises bumper post chamber, liquid level post 7, connecting pipe 5 and scaleplate 6, the bumper post chamber is connected to the lower end of storage tank 1, liquid level post 7 vertically arranges, and is connected by connecting pipe 5 between liquid level post 7 and the bumper post chamber, and scaleplate 6 be arranged in parallel with liquid level post 7.The bumper post chamber comprises glass visor 3 and bumper post 4, and the upper end of glass visor 3 is connected to the lower end of storage tank 1 by flanged connecting pipe, be tightly connected between the lower end of glass visor 3 and the bumper post 4.Connecting pipe between glass visor 3 and the storage tank 1 is provided with valve 2.Liquid level post 7 is the glass tube of 1cm for internal diameter, and the height of liquid level post 7 is more than or equal to the height of storage tank 1.The caliber of connecting pipe 5 is identical with liquid level post 7, and the corner of connecting pipe 5 is the arc of rounding off.Scaleplate 6 is wooden boards, and length and thickness can be selected voluntarily according to measuring needs, and general painted white is with protection sheet material and sign scale.Be connected by rubber tube between liquid level post 7 and the connecting pipe 5.
