Sealing ring of high-pressure electromagnetic flowmeter

Abstract

The invention belongs to the field of high-pressure electromagnetic flow meters, and discloses a high-pressure electromagnetic flow meter sealing ring which comprises a ring body. A first protruding ring is arranged on one side of the ring body, a first sealing ring groove is formed in the side, close to the edge of the ring body, of the first protruding ring, and a first sealing ring is arranged in the first sealing ring groove. A second sealing ring groove is formed in the side, provided with the first protruding ring, of the ring body, a second sealing ring is arranged in the second sealing ring groove, and the second sealing ring groove is located between the first protruding ring and the ring hole of the ring body. A third sealing ring groove is formed in the other side of the ring body, and a third sealing ring is arranged in the third sealing ring groove; the inner wall and the outer wall of the first protruding ring are each provided with a chamfer used for being matched with the end face of the high-pressure electromagnetic flowmeter to be sealed. The on-site installation requirement and construction difficulty are reduced, the sealing effect is good, the testing efficiency is improved, and the production, installation and maintenance cost is effectively reduced.

Description

technical field [0001] The invention belongs to the field of high-voltage electromagnetic flowmeters, and relates to a high-voltage electromagnetic flowmeter sealing ring. Background technique [0002] With the development of information construction, flow measurement and control are widely used in chemical industry, metallurgy, water supply and drainage, steel, coal, paper, food, textile and environmental protection and other industrial sectors and municipal management, water conservancy construction and other fields, the market demand is large. Flowmeters with various measurement principles for gases and liquids, such as the industry’s mainstream electromagnetic flowmeters, Coriolis force mass flowmeters, turbine flowmeters, vortex flowmeters, ultrasonic flowmeters, orifice flowmeters and differential pressure flowmeters All have good application effects. [0003] Existing flowmeters are generally flanged, and the withstand pressure is generally small. In view of this, m...
