Abstract
The utility model discloses a U-shaped tube pressure gauge. The U-shaped tube pressure gauge comprises a backboard of which the front surface is provided with a graduation ruler; the front surface of the backboard is further provided with a U-shaped transparent tube; a floating ball is arranged in each side tube of the U-shaped transparent tube; two side tubes of the U-shaped transparent tube are arranged at two sides of the graduation ruler; and the upper end of one side tube extends outwards and is connected with a needle valve. When the U-shaped tube pressure gauge is used, the needle valve is connected with an on-site tube; the floating balls in the side tubes are at different levels under the effect of the pressure in the on-site tube; the level difference of the floating balls can be indicated by the graduation ruler; and an actual pressure value of a site can be calculated through using a formula of 1 mm water column=1/102000 PA. The U-shaped tube pressure gauge of the utility model is advantageous in simple operation, safety and reliability. With the U-shaped tube pressure gauge adopted, a pressure value can be measured with one step; working time can be effectively shortened; measurement can be completed in 10 seconds; maintenance hours can be decreased by more than 30%; working efficiency can be improved more than 70%; and therefore, long time stay in harmful environments of maintenance personnel can be avoided, and harm to the maintenance personnel can be reduced.
Description
Technical field
The utility model belongs to the survey instrument technical field, is specifically related to a kind of U-shaped tube manometer.
Background technology
During the on-the-spot new setting pressure transmitter of smelter, often do not know on-the-spot force value, at this time need to change the pressure unit of different ranges, to measure its force value accurately.This kind mode operates very loaded down with trivial details, longevity of service, and work efficiency is low.Simultaneously, the site environment of setting pressure transmitter has again larger harmfulness, such as the environment such as: high-altitude, coal gas, radiation, high temperature, dust be large.The maintenance personal because needs are in the harm environment for a long time, very easily damages the maintenance personal in the pressure unit process of changing different ranges.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, reasonable in design, simple to operation, can effectively shorten working hours, and increases work efficiency, and avoids the maintenance personal to locate for a long time to endanger in environment, reduces the U-shaped tube manometer that the maintenance personal is damaged.
For achieving the above object, the technical solution adopted in the utility model is: this pressure gauge comprises that the front is provided with the backboard of rule, is characterized in: also be provided with in the front of backboard the U-shaped transparent pipe that all is equipped with ball float in each side pipe; Two side pipes of this U-shaped transparent pipe are positioned at rule both sides, and the upper end of one side pipe stretches out and is connected with needle-valve.
Perpendicular to the ground before the utility model uses, and be filled with suitable quantity of water to U-shaped transparent pipe, the ball float in each side pipe is because the Communicating device principle is positioned on the same level position.During use, needle-valve of the present utility model and field pipes are joined, this moment is at the scene under the pressure-acting in pipe, drop can appear in the ball float in side pipe, this drop is read by rule, and the formula of recycling one millimeter of water=1/102 kPa can be calculated on-the-spot actual pressure value.This formula is calculated by following: by p=ρ gh, g=9.8m/s
2=9.8N/kg, as can be known, 1kPa=1000Pa=1000kg/m
3* g * h, the substitution data get h=0.102m, and therefore 1 kPa is equivalent to 102 millimeters of water, draws a millimeter of water=1/102 kPa.When the utility model measurement, debugging and the measured pressure of verification, simple to operation, safe and reliable, once just can measure force value, the pressure unit that need not to change different ranges is tested, effectively shortened the working time, Measuring Time can be completed in 10 seconds, more than 30%, increased work efficiency more than 70% in the time of can reducing the check man, thereby avoid the maintenance personal to locate for a long time to endanger in environment, reduce that the maintenance personal is damaged.The utility model is simple in structure, reasonable in design, lightweight, volume is little, easily manufactured, applicability strong, have wide range of applications, and has filled up this type of manometric blank.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in the figure, the utility model comprises that the front is provided with the backboard 1 of rule 2.The length of its dorsulum 1 is 1150mm, and rule 2 is the scale of 1000mm.Also be provided with in the front of backboard 1 the U-shaped transparent pipe 3 that all is equipped with ball float 7 in each side pipe.The diameter of U-shaped transparent pipe 3 is 10mm, and overall length is 3 meters.Two side pipes of this U-shaped transparent pipe 3 are positioned at rule 2 both sides, and the upper end of one side pipe stretches out and is connected with needle-valve 6.This needle-valve 6 is connected with U-shaped transparent pipe 3 one side pipes by connecting pipe 5 and connector 4, adopts this kind connected mode, in case needle-valve 6 breaks down, conveniently it is changed.
