Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a limit-amplified, non-dismantling, calibrated and zero-adjustable pressure gauge to solve the problem that existing pressure gauges have measurement limits, and pressure gauges basically have a single limit value. The pressure value inside the measured object rises rapidly. When the measurement limit of the measuring pressure gauge is exceeded, it is easy to burst the gauge, which will make it difficult for the pressure gauge to evaluate and measure the existing pressure in the measured limit value.

Abstract

The invention provides a limit amplification non-detachable calibrated and zero-adjustable pressure gauge. The method is installed inside the watch frame, the dial is provided with a transparent scale, the clip and the dial are fixedly connected together, and the limit amplification device is installed inside the dial by embedding. The invention can pass the passive test of the adjustment mechanism during the test. After reaching the limit, through the interaction with the amplification mechanism, the booster ring can be converted to a fixed object, and then released from the tense state, and superimposed with the force of the adjustment mechanism, the upper limit of the pressure gauge can be increased, and the measured The pressure value inside the object is rising rapidly, and the test upper limit of the pressure gauge can be increased once to reduce the chance of bursting the gauge, and the test limit of the pressure gauge can be quickly restored without disassembly.

Description

technical field [0001] The invention belongs to the field of pressure instruments and meters, and more specifically relates to a limit amplification non-detachable calibrated and zero-adjustable pressure gauge. Background technique [0002] Pressure gauges are mainly used to detect and judge physical measurements that are difficult to accurately judge and measure by human sensory organs such as gases and liquids. The pressure gauge can be used to accurately judge and detect its internal pressure. Since the pressure of the measured object is basically in an unstable Change state. [0003] Based on the above description, the inventors found that the existing limit amplification non-detachable calibrated and zero-adjustable pressure gauge mainly has the following deficiencies, such as: [0004] Because pressure gauges have measurement limits, and pressure gauges basically have a single limit value, once the pressure value inside the measured object rises rapidly and exceeds th...
