Problems solved by technology

[0006] Third, the width of the relatively concave square groove 13 of the existing pressure gauge is usually larger than that of the oil seal ring 14. Under the influence of stress, the oil seal ring 14 of the diaphragm 12 will slide in the groove width of the upper and lower two concave square grooves 13, which not only affects the sealing effect of the pressure gauge, but also makes the diaphragm 12 no longer have a better peripheral balance stress

Embodiment Construction

[0015] Such as image 3 , 4 As shown, the present invention is jointly made up of components such as a table seat 20, a table head 30 and a diaphragm 40, wherein:

[0016] The watch seat 20 is a tubular seat body provided with an external thread 21 and a hollow inner diameter 22 . One end of the table base 20 is provided with a setting surface 23, and an annular arc groove 24 is opened on the setting surface 23, and the annular arc groove 24 is connected to the table base 20 by using a smooth arc angle 25 on the peripheral edge. The setting surface 23.

[0017] The meter head 30 is a pipe body provided with an internal thread 31 , a hollow inner diameter 32 and a measuring member 36 . The hollow inner diameter 32 is connected with its measuring member 36, the inner thread 31 corresponds to the outer thread 21 of the watch base 20, and the hollow inner diameter 32 corresponds to the hollow inner diameter 22 of the watch base 20. One end of the watch base 20 is formed with a...

Abstract

The present invention relates to a diaphragm combining structure of pressure gauge. On the pressure gauge seat and pressure gauge head the correspondent ring curved groove is made respectively, the curvalure of two ring curved grooves is correspondent to the oil seal ring of peripheral side of diaphragm of pressure gauge and every ring curved groove can be connected with mounting surface of pressure gauge seat and pressure gauge head by utilizing curved angle. The adoption of said invention can make the oil seal ring of pressure gauge diaphragm be forced uniformly and stably, and the curved angle of every ring curved groove can protect the oil seal ring against scuffing.

Description

technical field [0001] The invention relates to a diaphragm combination structure of a pressure gauge. Background technique [0002] Due to the increasing living standards of modern people, the quality requirements for various industrial products are also getting higher and higher, and industrial measuring tools directly affect the accuracy and precision of products. Among them, the measurement of various pressure gauges Measuring accuracy and service life (durability) are the primary considerations for buyers before purchasing. Therefore, for pressure gauge manufacturers, how to develop pressure gauge products with the above-mentioned functions is the most important design index during production; and the problems presented in the above content are the motivations for the research and development of the present invention. [0003] Common pressure gauges currently on the market such as figure 1 As shown, it includes a meter seat 10, a meter head 11 and a diaphragm 12. The...
