Abstract
The utility model discloses a tool for measuring the test pressure of a storage tank. The tool for measuring the test pressure of the storage tank comprises a bracket. The bracket is provided with a scale. A pipeline is fixed on the bracket through a clip. One end of the pipeline is provided with an opening, and the other end is connected with a joint and a valve. The pipeline is U-shaped. Compared with a pressure gauge, the device has the characteristics of accurate measurement, convenient operation, convenience, rapidness and the like. During construction, the efficiency of the device is high, and the project quality and the construction safety are easy to control, thus the project cost is effectively reduced, the energy is saved, and the environment is protected.
Description
Technical field
The utility model relates to a kind of storage tank, is specifically related to a kind of instrument of measuring pressure of storage tank.
Background technology
Storage tank belongs to nonstandard, normal pressure equipment, general volume is larger, field fabrication is welded, actuating medium is generally water, wet goods liquid medium, some medium such as chemical industry oil product have inflammable and explosive characteristic, so fabrication and installation will be carried out the tank body pressure test after complete, minute malleation test and negative pressure are tested, to check intensity and the tightness of tank body, test pressure is generally lower.Tank volume is large, and weld seam is many, and it is larger that field fabrication welding is affected by operating condition, so be an important process of storage tank check to the pressure test of storage tank.In process of the test, must strict Control experiment pressure, namely can not be lower than test pressure and do not reach test effect; Can not surpass again test pressure and cause tank structure destruction even the generation security incident, thus strict Control experiment pressure wanted, to reach check purpose.
Method mainly is by buying the setting pressure table, reading tensimeter numerical value and carry out pressure control at present.Usually adopt not only price of tensimeter, and need the purchase polylith to test, be not easy buying because test pressure is low, when tensimeter breaks down, also cause easily above test pressure and cause danger.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and a kind of instrument of measuring tank test pressure is provided, and can measure easily test pressure, carries out the experiment of storage tank intensity experiment and tightness.
The technical solution of the utility model realizes in the following manner: a kind of instrument of measuring tank test pressure, comprise support, support is provided with scale, and device for cleaning pipeline is crossed clamp and is fixed on the support, pipeline one end opening, the other end are connected with joint and valve, and it is U-shaped that pipeline is.
Described support is wooden pillar, and scale is engraved on the support.
This device is compared with tensimeter, have metering accurately, convenient operation, the characteristics such as convenient and swift.So this device when construction work efficiency is high, construction quality and construction safety are controlled easily, reduce project cost effectively, energy-conserving and environment-protective.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of instrument of measuring tank test pressure comprises support 1, and support 1 is provided with scale 4, and pipeline 3 is fixed on the support 1 by clamp 2, and pipeline one end is open, the other end is connected with joint and valve, and pipeline 3 is U-shaped.
Described support 1 is wooden pillar, and scale 4 is engraved on the support 1.
During use, be U-shaped pipeline 3 interior injection suitable quantity of water, this moment, the liquid level at pipeline 3 two ends was the same, did not have liquid level difference.In the tank body flood-pot experiment, after water injects tank interior and reaches lower 1 meter of design liquid level, the tank body total interface is sealed, only reserve an interface at the tank body top, be connected with the joint of pipeline 3 one ends, this moment, pipeline 3 one ends communicated with storage tank, and the other end communicates with atmosphere.Tank body continues water filling, if at this moment the water column at pipeline 3 two ends does not have liquid level difference, illustrates that then the tank body tightness is poor, and the leak point is arranged, and can check immediately the leak point this moment.If tank body is not revealed, then pipeline 3 can descend with the tank connected end liquid level of storage, and an end liquid level that communicates with atmosphere can rise, and two ends can slowly form liquid level difference, can conveniently observe difference according to the scale 4 on the support 1.According to 1 standard atmospheric pressure=1.013 * 10
5Pascal=10.336 meter water column pressure can determine the current pressure value by liquid level difference, when reaching design experiment pressure and keeping the long enough time, illustrates that the tank body tightness is good, and meets the malleation requirement of experiment.
In like manner, slowly discharge the water in the tank body in the negative pressure experiment, pipeline 3 two ends form liquid level difference equally, when reaching design experiment pressure and keeping the long enough time, tank body, tank deck illustrate that without leakage, without distortion the tank body tightness is good, intensity meets the requirements, the negative pressure stand the test.
