Problems solved by technology

[0003] Diesel engines are equipped with many valves to circulate diesel oil, among which the control valve is an important valve, and then the control valve will inevitably encounter faults after long-term use, resulting in parking for repairs, such faults include positioner problems, cylinder air leakage and other problems
Once these problems occur, they need to be shut down to deal with them, which will affect the production and reduce the output

Abstract

The invention relates to a high-quality pressure control valve. The high-quality pressure control valve is characterized by comprising a control valve body (1), wherein the control valve body (1) comprises a valve body (2), and a valve rod (3) is connected to the valve body (2); an execution mechanism (4) is fixed at the tail end of the valve rod (3); the outer part of the part, exposed out of thevalve body (2), of the valve rod (3) is sleeved with a locking device (5), the locking device (5) is composed of a fixing block (6) and a locking rod (7), and the tail end of the locking rod (7) is in contact with the part, arranged in a longitudinal through hole (6.1), of the valve rod (3); and a flow monitor is arranged in a pipeline of the rear side of the valve body (2), and corrosion-resistant coatings coat the valve body (2) and the execution mechanism (4). According to the high-quality pressure control valve, when the valve needs to be repaired, as long as the valve rod is fixed through the locking rod, the valve rod cannot move, so that the valve can be repaired without disassembling the executing mechanism, parking processing is avoided, and normal proceeding of production is guaranteed.

Description

technical field [0001] The invention relates to a high-quality pressure control valve, 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...
