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

Embodiment Construction

[0012] see figure 1 and figure 2 , the present invention relates to a pressure control valve with an alarm, including a control valve 1, the control valve 1 includes a valve body 2, the valve body 2 is connected with a valve stem 3, the end of the valve stem 3 is connected with the actuator 4 phases are fixed, so as to control the actuator 4 to move back and forth. The outer part of the valve stem 3 exposed to the valve body 2 is covered with a locking device 5. The locking device 5 is composed of a fixed block 6 and a locking rod 7. The fixed There is a longitudinal through hole 6.1 in the middle of the block 6, and the valve stem 3 is fixed with the actuator 4 after passing through the longitudinal through hole 6.1. The side of the fixed block 6 is provided with a transverse blind hole 6.2, and the transverse blind hole 6.2 has a There are internal threads, and the locking rod 7 has external threads, and the locking rod 7 is fitted in the transverse blind hole 6.2 of the f...

Abstract

The invention relates to a pressure control valve with an alarm. The pressure control valve is characterized by comprising a control valve (1), wherein the control valve (1) comprises a valve body (2), a valve rod (3) is connected to the valve body (2), the tail end of the valve rod (3) is fixed to an actuating mechanism (4), a locking device (5) sleeves a part, which is exposed to the valve body(2), of the valve rod (3), the locking device (5) is composed of a fixed block (6) and a locking rod (7), the tail end of the locking rod (7) makes contact with the valve rod (3) in a longitudinal through hole (6.1), and the alarm is arranged in a front pipeline of the valve body (2). When the pressure control valve with the alarm needs to be repaired, the valve rod cannot move only by fixing thevalve rod by virtue of the locking rod, so that the valve can be repaired without disassembly of the actuating mechanism, shutdown processing is avoided, and normal production is guaranteed.

Description

technical field [0001] The invention relates to a pressure control 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 gasolin...
