Example 1

A multifunctional pressure cover capable of preventing removal comprises a floating ball liquid level sensor 1, a magnetic detection ring 2, a magnetic ring 3, a pressure cover body 4, a reset spring piece 5, a reset spring 6, an escape plug 7, a pressure detector 8, a nut 9, a high-level water tank 10, cooling water 11, an engine controller 12 and an escape hole 13 as shown in figure 1.

The pressure lid sealing connection is at high-level water tank top, and pressure lid center is provided with escape plug 7, and the escape plug comprises the sealing of round conical and cylinder type connecting portion, be provided with the bubble escape hole on the pressure lid, the exit portion setting of bubble escape hole is on the contact surface of pressure lid and sealing, and when high-level water tank internal pressure did not reach the setting value, the escape plug was blocked the bubble escape hole, and when high-level water tank pressure was greater than the setting value, the escape plug was opened.

The sealing part top is also provided with a round sealing plate, so that the sealing stability is further ensured.

The connecting portion outside is provided with reset spring, the bottom threaded connection of connecting portion has the nut, reset spring's top contact pressure lid bottom, nut reset spring's bottom coupling nut. The position of the reset spring is fixed through the nut, so that when the pressure in the water tank is reduced due to overflow of air bubbles, the escape plug can be driven to move downwards through the reset spring to block the escape hole, and the high-level water tank is sealed again.

The outside of the reset spring is provided with a reset spring piece, the position of the reset spring is further fixed, and the reset spring piece 5 is connected with the nut 9 and the escape plug 7 together and can synchronously move together.

When the engine works and runs, cold water in the engine cavity is gradually heated, part of hot water of the engine can enter the high-level water tank 10, meanwhile, certain bubbles can be generated in the process of heating cooling water, and the bubbles can move along with water to the high position, so that the bubbles enter the high-level water tank, and the bubbles are accumulated in the high-level water tank and generate pressure. When the engine starts running, the head tank pressure increases gradually until the pressure increases to the pressure set point. The pressure in the water tank acts on the reset spring piece 5, the pressure in the water tank continuously rises, and after overcoming the action of the reset spring 6, the reset spring piece 5 drives the nut 9 and the escape plug 7 to move upwards, so that the bubble escape hole is opened, the air is led to the atmosphere, and the pressure in the water tank is released. When the pressure in the water tank is reduced, the escape plug 7 moves downwards under the combined action of the reset spring piece 5 and the reset spring 6, so that the bubble escape hole is closed.

The pressure cover body 4 is provided with a floating ball liquid level sensor for sensing the liquid level in the high-level water tank, and the circulating water part can escape along with the increase of the running time of the engine, so that the cooling water in the engine body can be reduced, and the floating ball liquid level sensor is used for sensing the liquid level.

The magnetic ring 3 and the magnetic detection ring 2 are respectively arranged on the pressure cover body 4 and the high-level water tank 10, and the magnetic ring 3 and the magnetic detection ring 2 are matched for use, so that whether the pressure cover body 4 exists or not can be monitored, and whether the position of the pressure cover body is in place or not can be monitored.

The pressure cover body 4 is provided with a pressure detector 8 for detecting the internal pressure of the high-level water tank.

Signals of the magnetic detection ring 2, the floating ball liquid level sensor 1 and the pressure detector 8 are respectively connected into the engine controller 12.

The engine controller 12 sets normal values of the floating ball liquid level sensor 1, the magnetic detection ring 2 and the pressure detector 8 for each engine as the standard for monitoring in daily work according to different demand states of the engines.

The magnetic detection ring 2 is matched with the magnetic ring 3 for use, so that the pressure in the high-level water tank 10 cannot be controlled because the pressure cover body 4 is prevented from being manually removed (in an uninstalled state) or not installed in place, and the pressure in the high-level water tank 10 cannot be ensured or the pressure is prevented from being controlled by mistake because the pressure cover body 4 is manually replaced. The magnetic detection ring 2 is connected to the engine controller 12, and when the engine runs, if the magnetic detection ring 2 cannot detect the magnetic ring 3 or the magnetic ring 3 which is not matched normally, the engine controller 12 generates an alarm signal to inform an operator of maintenance.

The pressure detector 8 can monitor the pressure in the high-level water tank 10 in real time, when the engine runs for more than the set time and the pressure in the high-level water tank is lower than the set value, the engine controller generates an alarm signal, for example, when the engine runs for 30min, the pressure in the high-level water tank 10 is still lower, and the engine controller 12 can judge that the engine pressure cover body 4 is not in place or leaks, so that the pressure in the high-level water tank 10 cannot be established. The engine controller 12 generates an alarm signal informing the operator of the service.

The utility model can meet the control of the cooling water pressure in the engine cavity, in particular, the utility model seals the high-level water tank by arranging the pressure cover, replaces the water pressure brought by the high liquid level with the air pressure generated by the air bubble generated in the hot water, and realizes the control of the pressure at the set pressure value by the escape plug, so that the high-level water tank is not required to be arranged at a relatively very high position, meets the use requirement of the engine, reduces the inconvenience caused by arranging the high-level water tank, monitors the quantity of the cooling water of the engine, and can monitor some abnormal states of the engine and provide audible and visual alarm signals.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
