Shockproof corrugated tube sight glass

Abstract

The invention relates to valve equipment, in particular to a shockproof corrugated tube sight glass suitable to be used in places of greater vibration. The sight glass consists of two outer flanges, two inner flanges and a transparent sight glass, wherein both ends of the transparent sight glass are fixed inside the two inner flanges; the inner flanges are fixed with the corresponding outer flanges through metal tube fittings which are corrugated tubes; and one end of each corrugated tube is fixed with each inner flange, while the other end is fixed with each outer flange. The shockproof corrugated tube sight glass has the advantages that: the sight glass adopts double-corrugated section design and the corrugated tubes also have certain toughness, thereby greatly improving the shockproof performance of the sight glass, prolonging the service life of the sight glass, reducing product leakage during vibration and basically avoiding the possibility of glass breakage; the sight glass can be widely used in various places, particularly in pharmacy, petrochemical industry, ocean platforms and the like; and the double-corrugated structure can also be grafted on other valve structures such as gate valves, stop valves, check valves and ball valves to improve shockproof effects during production operation.

Description

technical field [0001] The invention relates to valve equipment, in particular to an anti-shock bellows sight glass suitable for use in places with relatively large vibrations. Background technique [0002] Sight glasses (valve components with transparent sight glasses) are widely used in pharmaceutical, offshore platforms, petrochemical and other fields. In these occasions with high vibration frequencies, valves with large internal vibrations often have a short service life. Especially the glass sight glass, due to excessive vibration, often shatters and cracks. In the application of pharmaceutical equipment, especially in the drug synthesis stage, if the glass sight glass breaks, it will lead to the scrapping of batches of drugs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a shock-proof bellows sight glass, which is especially suitable for places with large vibrations and prolongs the service life of the s...

AI Technical Summary

Problems solved by technology

[0005] The present invention is aimed at the design of the double corrugated section (the bellows are used at both ends) with special effects such as shock absorption and lifelikeness when the centrifuge is dehydrating. Above the corrugation, the use performance is improved, even in the case of high vibration frequency, it can also protect the sight glass so that it is not easy to break, the maintenance period is as long as 4 to 5 months, or even one year, and it can completely prevent the sight glass from being broken Defects
