Description

A kind of differential pressure indicator
Technical field
The utility model relates to a kind of physical measurement techniques field, particularly relates to a kind of differential pressure indicator.
Background technology
Sylphon differential pressure indicator be the film sylphon made using elastic metallic as sensing element, atmospheric pressure is converted to the elastic displacement of sylphon by it, drives pointer by lever and gear train.When clockwise direction deflects, pointer just indicates the variable quantity that air pressure raises, otherwise, when pointer counterclockwise deflects, indicate the variable quantity that air pressure reduces.When the elastic stress of sylphon and atmospheric pressure balance each other, pointer just stops operating, and the atmospheric pressure value at this moment indicated by pointer is exactly atmospheric pressure value at that time.For measuring the positive and negative pressure of pharmaceutical factory, Electronics Factory's toilet's clean room, Heating,Ventilating and Air Conditioning (HVAC), purification air-conditioning, clean bench Airshower chamber special table, the detection etc. of clean air conditioner screen pack pressure reduction.
Current existing differential pressure indicator can only measure pressure reduction, can not the pressure of measurement gas, and inconvenient operation, complex structure, carries inconvenience.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of multiple functional, and can measure pressure reduction and can measure air pressure again, operation is simple and reliable, differential pressure indicator easy to carry.
For solving the problem, the utility model adopts following technical scheme:
A kind of differential pressure indicator, comprise housing, high pressure chest, low pressure chamber and torquer, described high pressure chest and low pressure chamber are located in housing, measuring diaphragm one and two-way valve one is provided with in described high pressure chest, measuring diaphragm two and two-way valve two is provided with in described low pressure chamber, measuring diaphragm one and measuring diaphragm two can produce distortion when air pressure changes, two-way valve one and two-way valve two can keep gas transmission, connecting link is provided with between described two-way valve one and two-way valve two, connecting link can be moved when producing pressure reduction, described two-way valve one is connected by connecting link with two-way valve two, described connecting link is provided with fork, fork can keep stable transmission reliable, described connecting link is connected with torquer by fork, described torquer is disposed with torque tube and gear train, described torquer is connected with gear train by torque tube, the rotation that torquer produces can be passed to gear train by torque tube, described gear train is provided with pointer, facilitate indicated pressure scale.
As preferably, described measuring diaphragm one and measuring diaphragm two undulate are arranged, and can stablize by holding structure when being out of shape.
