Cock valve with alarm

Abstract

The invention relates to a cock valve with an alarm. The cock valve is characterized in that the cock valve comprises a valve body (1), the middle of the valve body (1) is provided with a valve seat (2), and the valve seat (2) and the valve body (1) are arranged in a separated from; a cock (5) is arranged in a middle through hole of the valve seat (2), the top of the valve body (1) is connected with a screw cap (7) through a thread, and the top of the screw cap (7) and a transversely-arranged handle (8) are hinged; and the screw cap (7) is rotated through the handle (8), and the alarm is arranged in a front side pipeline of the valve body (1). According to the cock valve with the alarm, disassembling and assembling are convenient, the maintenance efficiency is improved, sealing performanceis good, and leakage prevention under high and low pressure can be achieved.

Description

technical field [0001] The invention relates to a plug valve with an alarm, which is mainly used in diesel engines and belongs to the technical field of valves. Background technique [0002] A diesel engine is an engine that burns diesel to obtain energy release. It has good thermal efficiency and economy. The diesel engine uses compressed air to increase the air temperature, so that the air temperature exceeds the self-ignition point of diesel, and then injects diesel and diesel spray. It ignites and burns by itself while mixing with air. Therefore, a diesel engine does not require an ignition system. At the same time, the oil supply system of the diesel engine is relatively simple, so the reliability of the diesel engine is better than that of the gasoline engine. Due to the limitation from deflagration and the requirement of diesel self-ignition, the compression ratio of diesel engine is very high. Both thermal efficiency and economy are better than gasoline engines. A...
