Structural improvement of pressure gauge

The present invention provides a structural improvement of a pressure gauge, especially a structural improvement of a simple structure, accurate measurement, long service life, and no angle limitation.

Press, a pressure gauge is a pressure measuring instrument that is usually limited to measuring pressure close to the atmosphere. In fact, the term "pressure gauge" is often used to refer to a class of instruments, that is, mainly using electronic instruments, floats or liquid columns to measure the pressure under hydrostatic conditions, although the electronic accuracy is higher, but The relative manufacturing cost is also high, so the floating ball type pressure gauge still has a high usage penetration rate.

Please refer to the first figure, which is a schematic diagram of the implementation of the conventional gas pressure gauge. As can be clearly seen from the figure, the pressure gauge body 9 includes the structure of the intake duct 91, the buoy 92, the spring 93, etc. When the air duct 91 enters, the buoy 92 is displaced to the position corresponding to the pressure scale on the pressure gauge body 9 according to the pressure intensity of the input gas, and is restored to the position of the scale zero by the spring 93 when the pressure is lowered. This is known as the magnitude of the pressure through the gas.

However, when the above gas pressure gauge is used, it is still necessary to improve the following problems and defects:

1. The movement of the buoy 92 is completely changed by the gas introduced by the single passage of the intake duct 91. During the change of the air pressure value, the direction of the air flow is easily shifted, causing the buoy 92 to tilt and touch the inner wall of the pressure gauge body 9, and Affect its accuracy.

2. The buoy 92 itself has no positioning structure and will be skewed by gravity. Therefore, if the gauge body 9 is not upright during use, the buoy 92 will inevitably lean against the inner wall of the pressure gauge body 9 to concentrate the incoming airflow to the other side. And affect its accuracy, and even cause wear and tear.

Therefore, how to solve the above problems and deficiencies in the past, that is, the applicants of the new type and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.

Therefore, in view of the above-mentioned shortcomings, the applicants of this new type have collected relevant information, and through multi-party evaluation and consideration, and through years of experience in the industry, through continuous trial and modification, they have designed this simple structure and accurate measurement. A new patented manufacturer with a long service life and no improvement in the use of pressure gauges.

The main purpose of the present invention is to uniformly distribute the introduced airflow around the air pressure indicator to prevent it from colliding with the receiving body to increase measurement accuracy and reduce wear.

In order to achieve the above object, the structure of the present invention comprises: a receiving body, and an air inlet for introducing a gas flow is formed at one end of the receiving body, and a gas pressure indicating member is disposed in the receiving body, and the air pressure is provided. A plurality of airflow guiding portions are arranged around the indicator member, so that the airflow is evenly applied to the outside of the air pressure indicating member, and a resisting portion is formed on a side of each of the airflow guiding portions facing away from the air inlet, for supplying airflow Pushing and driving the air pressure indicator; when the user applies the new type to the gas pressure measurement, the present invention is disposed on the air flow path of the gas output device, so that the air flow is introduced into the receiving body through the air inlet. At this time, due to the presence of the airflow guiding portion, the airflow direction is evenly guided to the periphery of the air pressure indicating member, thereby effectively preventing the air pressure indicating member from coming into contact with the inner wall of the body, and at the same time, the reaction force of the airflow blowing toward the resisting portion is utilized. The displacement of the air pressure indicator is increased, and the sensitivity of the air pressure indicator is increased, thereby increasing the accuracy of the air pressure measurement and reducing the wear rate between the air pressure indicator and the accommodating body.

With the above technology, it is possible to achieve breakthroughs in the problems of unstable gas flow paths, low accuracy of pressure measurement, and structural wear easily, and achieve practical advancement of the above advantages.
