Novel warning ball valve

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 at 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, the bottom of the miniature air cylinder is provided with a sensor, 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 between the valve body and the valve seat of the ball valve is regulated, the sealing ring consumed through abrasion is tightly pressed, and the influence on the sealing performance of the sealing ring is prevented, 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 alarm ball valve that can automatically detect whether the valve body and the valve seat are well sealed. Background technique [0002] Ball valve is a valve with full diameter and low flow resistance, which is very suitable as a valve for long-distance pipelines. The demand for pipeline ball valves in the global energy, chemical and other industries has been growing steadily, especially in China, the world's second largest economy, with its rapid development in the petroleum, natural gas and chemical industries, urban construction and other industries, pipeline ball valves are used in engineering. One of the key equipments, ushered in unlimited development and market opportunities. At present, the ball valve attaches great importance to the sealing performance of the ball, while the sealing performance between the valve body and the valve seat is relatively light. And other issue...

AI Technical Summary

Problems solved by technology

[0003] The purpose of this invention is to provide a new type of alarm ball valve that can automatically detect whether the seal between the valve body and the valve seat is good. The operator does not know about air leakage, and the spring between the valve body and the valve seat is adjusted through the position adjustment device at the rear of the spring, which solves the problem of poor sealing between the ball valve body and the valve seat
