AI Technical Summary

Problems solved by technology

The precision of the pressure gauge is high. After the pressure gauge is assembled, the performance and sensitivity of the pressure gauge need to be verified. The traditional method is to connect the joint of the pressure gauge to the air source equipment, and then press down on the pressure gauge to make it The pressure gauge is placed stably and then tested. However, this method takes a long time and is not convenient for quick calibration of the pressure gauge.

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0021] Such as figure 1 Shown: a pressure gauge calibration joint, which is composed of a conversion joint 1 and a support hose 2. The conversion joint 1 has a through hole 3 in the axial direction, and the lower end of the through hole 3 is connected with a gas nozzle 5. The conversion joint 1 from top to bottom is a mounting part 1a, a bolting part 1b and a connecting part 1c. The connecting part 1c is provided with external threads, and the mounting part 1a is provided with 3 circles of barbs. Of course, the barbs It can also be 1, 2, 4 or 5 turns, etc., as long as the pillar hose can be stably installed on the installation part; An installation groove 4 is provided between the connecting parts 1c, and a sealing ring is sleeved in the installation groove 4,

[0022] The lower part of the support hose 2 is sheathed on the installation part 1a, and t...

Abstract

The invention discloses a verification connector of a pressure gage. The verification connector is characterized by comprising a conversion joint and a support column hose. A through hole is axially formed in the conversion joint, the conversion joint sequentially comprises an installation portion, a fastening portion and a connecting portion from top to bottom, the connecting portion is provided with external threads, the installation portion is provided with at least one circle of barb, the lower portion of the support column hose is arranged on the installation portion in a sleeved mode, and the support column hose is communicated with the conversion joint. According to the verification connector of the pressure gage, the pressure gage can be easily assembled and disassembled, and verification efficiency of the pressure gage is improved.

Description

technical field [0001] The invention belongs to the technical field of pressure gauge testing, and in particular relates to a pressure gauge calibration joint. Background technique [0002] Pressure gauge (English name: pressure gauge) refers to an instrument that uses elastic elements as sensitive elements to measure and indicate pressure higher than the environment. The application of pressure gauges is extremely common, and it pervades almost all industrial processes and scientific research fields. It can be seen everywhere in heat pipe network, oil and gas transmission, water supply and gas supply system, vehicle repair and maintenance factory and shop. Especially in the process of industrial process control and technical measurement, due to the high mechanical strength and convenient production of the elastic sensitive components of mechanical pressure gauges, mechanical pressure gauges are more and more widely used. [0003] The pressure gauge transmits the pressure ...
