Abstract

The invention provides a novel sealing ball valve, which comprises a valve body and a valve seat, wherein the valve body is arranged on the valve seat, a sealing ring is arranged on the valve seat, the bottom of the valve seat is provided with a ball body, an inserting element is arranged in a contact part of the valve seat and the ball body, a spring is arranged on the valve body, the bottom of the sealing ring is provided with a miniature air cylinder, the miniature air cylinder is arranged inside the valve seat, a telescopic rod of the miniature air cylinder is in contact with the surface of the sealing ring, a sensor is arranged at the bottom of the miniature air cylinder, and the miniature air cylinder is controlled to regulate the position of the sealing ring through the sensor. Through the arrangement of the miniature air cylinder and the sensor, the sealing ring arranged between the valve body and the valve seat of the ball valve is regulated, the sealing ring consumed through abrasion is tightly pressed, the sealing performance of the sealing ring is prevented from being influenced, in addition, the ball body is sealed through the inserting element and an auxiliary baffle strip, and the sealing performance is further improved.

Description

technical field [0001] The invention relates to the field of valves, in particular to a novel sealing ball valve with good sealing performance. Background technique [0002] Ball valve is a valve with full bore and low flow resistance, which is very suitable as a valve for long-distance pipelines. It is a new type of valve with the fastest development in the past 50 years. The demand for pipeline ball valves in global energy, chemical and other industries has been growing steadily, especially in China, the world's second largest economy, with its rapid development in oil, natural gas and chemical industry, urban construction and other industries, pipeline ball valves are used as engineering One of the key equipment, usher in unlimited development and market opportunities. [0003] Petroleum, natural gas, chemical industry and energy account for more than 70% of valve demand. Taking the continuous development and changing demand of oil and natural gas as an example, its dema...
