Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1 to 4, the automatic ventilation device for cooling water of a diesel engine is installed on a cooling water ventilation pipe 1 of the diesel engine, and comprises a ventilation valve 2 and an alarm device 3 for controlling the flow, wherein the alarm device 3 is communicated with the cooling water ventilation pipe 1 of the diesel engine through a pipeline, a main three-way valve 4 and a normally-open valve 5 are sequentially communicated between the alarm device 3 and an inlet end of the ventilation valve 2 from bottom to top, an outlet end of the ventilation valve 2 is connected with an auxiliary three-way valve 6 through a bent pipe, and a normally-closed valve 7 is communicated between the auxiliary three-way valve 6 and the main three-way valve.
The alarm device 3 comprises a valve body 31, the inlet end of the valve body 31 is communicated with the cooling water vent pipe 1 of the diesel engine, the outlet end of the valve body 31 is communicated with the main three-way valve 4, a connecting seat 32 is hermetically arranged on the side part of the valve body 31, a supporting seat 33 extending into the valve body 31 is arranged on the inner side of the connecting seat 32, a connecting seat 34 is arranged on the supporting seat 33, a floater 35 is hinged to the connecting seat 34, and the supporting seat 33 is provided with a flow controller and can touch the flow controller when swinging to the lowest part.
A floating ball 22 is arranged in the vent valve 2, and when cooling water is gushed into the vent valve 2, the floating ball 22 can float upwards and close the outlet end of the vent valve 2.
A gas-guiding groove 21 is provided in the inlet end of the purge valve 2, and gas can pass through the gas-guiding groove 21 and be discharged from the outlet end of the purge valve 2 when the floating ball 22 stays at the inlet end of the purge valve 2.
The main three-way valve 4, the normally-closed valve 7 and the auxiliary three-way valve 6 form a bypass pipeline, the bypass pipeline is used for detecting whether the alarm device 3 and the vent valve 2 in the device normally work or not, and can also be used for discharging and sampling cooling water, and the device has the advantages of complete functions, high automation degree, high working efficiency, low cost and the like.
A floating ball 22 which can float on the liquid level is arranged in the vent valve 2, and the floating ball 22 blocks the outlet end of the vent valve 2 along with the height of the liquid level under the action of the gravity of the floating ball 22 and the buoyancy of the cooling water entering the vent valve 2, thereby playing a sealing role.
After the gas of the cooling water enters the alarm device 3 (at this time, the normally open valve 5 is in an open state, and the normally closed valve 7 is in a closing device), the gas sequentially passes through the main three-way valve 4 and the normally open valve 5 and then enters the vent valve 2 (at this time, the floating ball 22 in the vent valve 2 stays at the inlet end of the vent valve 2), and the gas enters the vent valve 2 through the gas guide groove 21, so that the gas is discharged from the outlet end of the vent valve 2 through the auxiliary three-way valve 6; when cooling water enters the alarm device 3, the alarm device 3 normally works when the floater 35 floats on the liquid surface at a specified angle, when the flow is too large, the cooling water can flow into the vent valve 2, at the moment, the floating ball 22 in the vent valve 2 floats on the liquid surface and props against the outlet end of the vent valve 2 to seal the outlet end of the vent valve 2, meanwhile, the valve body 31 of the alarm device 3 is filled with the cooling water, the floater 35 in the floating state originally sinks under the action of self gravity until touching the flow controller, and therefore the flow control valve transmits an alarm signal to the cooling water supply pump, and the supply pump reduces the supply amount. When closing the normally open valve 5 and opening the normally closed valve 7, the excess cooling water can be drained off and at the same time be used to check whether the device is working properly.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
