Abstract
The utility model provides a simple and precise spring tube type pressure gauge, which comprises a case, a dial arranged on the case and a pointer arranged in the middle of the dial. The pointer is connected with a transmission mechanism, the transmission mechanism is connected with a spring tube through a connecting rod, the spring rube is connected and provided with a balance spring, the balance spring is connected with the transmission mechanism, the two ends of the balance spring are respectively connected to the case, and the bottom of the case is fixedly provided with a joint. The simple and precise spring tube type pressure gauge has the advantages of reasonable design, compact structure, simple manufacture, convenient installation, high detection precision, long service life and high economic benefit.
Description
Technical field
The utility model relates to a kind of simple surveying instrument, is specifically related to simple and easy accurate spring-tube type manometer.
Background technology
Carry out the conveying of liquid or gas in petroleum pipe line time, need to be in pipeline setting pressure instrument, be used for detecting at any time the pressure of pipeline medium, existing manometer can be divided into two large classes substantially: a class is traditional electromechanical pressure instrument, another kind of is digital manometer, electromechanical pressure instrument is Passive Shape Control device, get final product work without external power supply, have cheap, advantage convenient for installation and maintenance, common electromechanical pressure instrument is because its structural design not rationally causes its accuracy of detection lower, and digital manometer needs external power supply to work, being not suitable for being used in pipeline carries.Because the shortcoming of above-mentioned instrument, it does not reach perfection inventor's thoughts, then exhausting the concentrated research of its intelligence overcomes, be engaged in this industry working experience for many years with it, and then develop simple and easy accurate spring-tube type manometer, and utilize simply design, can make the utility model reach simple in structure, easy to operate, precision is high effect.
Summary of the invention
Technical problem to be solved in the utility model is to provide simple and easy accurate spring-tube type manometer, reasonable in design, and compact conformation is manufactured simply, and easy for installation, accuracy of detection is high, long service life, and economic benefit is high.
For solving above-mentioned existing technical matters, the utility model adopts following scheme: simple and easy accurate spring-tube type manometer, comprise watchcase, be arranged on the scale on watchcase and be arranged on the middle pointer of scale, described pointer connection for transmission mechanism, described gear train is connected with bourdon tube through connecting rod, on described bourdon tube, is connected with hairspring, and described hairspring is connected with gear train, and the two ends of hairspring are connected respectively to watchcase, described watchcase bottom is fixed with joint.
As preferably, described gear train is provided with some adjustment screws, is provided with the adjustment screw for connection for transmission mechanism and connecting rod in described adjustment screw.By adopting this set, make transmission more coherent, improve the stability of work.
As preferably, described scale is provided with lining ring.By adopting this set, reasonable in design, good looking appearance, easily manufactured.
Beneficial effect:
The utility model adopts technique scheme that simple and easy accurate spring-tube type manometer is provided, the deficiencies in the prior art are made up, improve the degree of accuracy of measuring, improved economic benefit, reasonable in design, compact conformation, manufacture simply, easy for installation, accuracy of detection is high, long service life, economic benefit is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, simple and easy accurate spring-tube type manometer, comprise watchcase 1, be arranged on the scale 2 on watchcase 1 and be arranged on the middle pointer 3 of scale 2, described pointer 3 connection for transmission mechanisms 4, described gear train 4 is connected with bourdon tube 6 through connecting rod 5, on described bourdon tube 6, is connected with hairspring 7, and described hairspring 7 is connected with gear train 4, and the two ends of hairspring 7 are connected respectively to watchcase 1, described watchcase 1 bottom is fixed with joint 8.Described gear train 4 is provided with some adjustment screws 9, is provided with the adjustment screw 10 with connecting rod 5 for connection for transmission mechanism 4 in described adjustment screw 9.Described scale 2 is provided with lining ring 11.
When real work, first check that whether each parts are intact, and whether the connection of each parts is smooth and easy, then joint 8 is received and detected in medium, the hairspring 7 being connected with watchcase 1 senses that stress reaction is to bourdon tube 6, the stressed stretching of bourdon tube 6, drive gear train 4 to work through connecting rod 5, thereby make pointer 3 deflections and on scale 2, reflect the pressure of measured medium, can adjust according to the actual requirements connecting rod 5 and meet different needs of work from the link position of gear train 4, the deficiencies in the prior art are made up, improve the degree of accuracy of measuring, improve economic benefit, reasonable in design, compact conformation, manufacture simple, easy for installation, accuracy of detection is high, long service life, economic benefit is high.
Specific embodiment described herein is only to the explanation for example of the utility model spirit, the utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
