Vacuum breaking warning device for air-water separator of water pump

The invention relates to a vacuum breaking warning device for a gas-water separator of a water pump, especially a warning function that allows the gas-water separator to effectively perform vacuum breaking under positive or negative pressure environments. It is the inventor of the invention.

By the way, general water pumps are used for emergency flood drainage, pumping underground sewage, or emergency water pumping in building basements, etc. The water pump has high mobility and does not need an external power supply, so it is often used for emergency rescue; however, when regional water accumulation occurs, or when excavating tunnels In projects such as pipelines, buried pipes, etc., pumps will also be used to pump out the accumulated water from the project site and other accumulated water, so as to make the accumulated water subside and allow the project to continue smoothly, or to make the accumulated water in low-lying areas subside smoothly

However, the inventor's previous design of the air-water separator for the traditional water pump still needs to be improved. In order to solve the problem of the vacuum pump being repeatedly sucked up by the atmosphere and the lack of it; the special research and development application Taiwan Patent No. I655371 is a water pump. The structure of the air-water separator, its The gas-water separator is mainly provided with an outer casing, one end of which is connected to the water pump cavity, and a buoy is arranged inside the outer casing, and the buoy is connected to one end of a lever group, and the other end of the lever group is connected to a vacuum breaker , the vacuum breaker is installed and pierced through the upper cover covering the outer casing, and the vacuum breaker is correspondingly connected to a vacuum pump to extract the air inside the gas-water separator, and the air inside the vacuum breaker There is a piston group, the piston group rises due to the buoy during vacuum extraction, and is connected to the upper cover through the connection of the lever group to block the vacuum pump from pumping the air at the end of the pump cavity, so that the vacuum breaker gradually reaches the limit Vacuum state.

The above-mentioned structure does improve the defects caused by the repeated suction of the traditional water pump; however, further looking at the vacuum break warning device of this structure, wherein a vacuum breaker is arranged on the upper cover, and the vacuum breaker is correspondingly arranged on the On one side of the airtight adjustment group and above the lever group, the vacuum breaker is arranged at the hole of the second step, which includes a ball seat, and the ball seat is embedded in the second step In the hole, an airflow channel is provided, and the airflow channel is connected to a container, and the container is provided with an aerophonic ball, and the airflow channel communicates with the second stepped hole, and is provided with a movable rod, and the movable The rod is located above the lever group, and can be moved between the airflow channel and the second stepped hole; thereby, when the lever group is raised by the buoy to activate the vacuum breaker, the outside air enters the In the inner space of the outer casing, the buoy is lowered and the lever group is linked, so that the piston group is separated from the upper cover, so that the vacuum pump continues to suck the air at the end of the water pump cavity.

Usually, when the general water pump is in operation, the air-water separator is mostly in a negative pressure state. Therefore, the structure of the air-water separator of the water pump in the aforementioned Taiwan Patent Publication No. I655371 can be normally applied to the general water pump under negative pressure. However, if there are some very special places, if the gas-water separator is used under positive pressure conditions, because the warning gas-sound ball has no external force constraints, the water pressure inside the gas-water separator will overflow in the direction of the gas-sound ball .

The reason is that, in view of this, the inventor, with years of rich experience in design, development and actual production in this related industry, specially provides a gas-water separator structure for a water pump, hoping that the vacuum breaker can be used in a positive or negative pressure environment. Can effectively provide the airtight adjustment group to produce a sealing effect, so as to achieve the purpose of better practical value.

In order to have a more complete and clear disclosure of the technical content used in the present invention, the purpose of the invention and the effects achieved, it will be described in detail below, and please also refer to the disclosed drawings and drawing numbers:

First of all, please refer to Figures 1 to 5, which are combined cross-sectional and partial enlarged cross-sectional views of the vacuum breaking warning device of the gas-water separator of the water pump according to the present invention, which are mainly in the gas-water separator (1) of the water pump The upper cover (11) is provided with a through hole (111), and a corresponding vacuum breaking warning device (2) is provided, which includes:

A ball seat (21) is correspondingly embedded in the through hole (111) of the upper cover (11), the upper end of the ball seat (21) is provided with a receptacle (211), and the lower end has a space ( 212), the space (212) communicates with the through hole (111), and a channel (213) communicating with the space (212) is provided at the bottom of the container (211);

An air sound ball (22), which is correspondingly arranged in the container (211) of the ball seat (21);

A buoyancy seat (23) is arranged in the space (212) of the ball seat (21), please refer to the sixth figure, the periphery of the buoyancy seat (23) is provided with a plurality of grooves (231 ), and combine a breaking rod (24) in the center, the breaking rod (24) is passed between the through hole (111) and the passage (213), and then corresponds to the buoyancy seat (23) The end face of the passage (213) is provided with an airtight gasket (25);

An outer cover (26) is correspondingly covering the outside of the ball seat (21), and the wall of the outer cover (26) is provided with an air hole (261) communicating with the outside.

In actual operation, please refer to the first to third figures, the gas-water separator (1) of the water pump of the present invention is correspondingly connected with the vacuum pump, and the gas-water separator (1) is provided with a buoy ( 12), the buoy (12) is connected to a connecting rod group (13), and the upper cover (11) is provided with an airtight hole (112) and a through hole (111), and the airtight hole (112) is An airtight adjustment group (3) is provided in the corresponding group, the airtight adjustment group (3) is connected with the connecting rod group (13), and the through hole (111) is correspondingly installed with a vacuum breaking warning device (2); When the vacuum pump starts to perform vacuum work, the air flows into the bottom of the air-water separator (1) from the end of the water pump cavity, and is drawn toward the air-tight adjustment group (3), so that the air passes through the air-water separator (1) and the air-water separator (1). The internal space of the buoy (12) and the connecting rod group (13) flows into the airtight adjustment group (3) to the upper cover (11), and the air hole (31) of the airtight adjustment group (3) can Leave and flow into the suction side of the vacuum pump [the air flow is indicated by the arrow in the figure]. After the vacuum pump makes the air flow through the arrow path, the vacuum degree in the gas-water separator (1) can be gradually increased.

When the vacuum pump makes the vacuum at the end of the pump cavity sufficient, the water at the end of the pump cavity will enter the air-water separator (1), and push the buoy (12) up. After the buoy (12) rises, it will pass through the connecting rod group ( 13) Drive the airtight adjustment group (3) to move downward, so that the piston (32) in the airtight adjustment group (3) is pulled down, and when the water level is high enough [that is, the buoy (12) rises to an appropriate Position], its pull-down range can make the piston (32) fit with the airtight hole (112) of the upper cover (11), and start to block the air circuit. To block the air circuit, the airtight design needs to be further considered, that is, the fit of the piston strength.

However, when the gas-water separator (1) is applied in a negative pressure state, the seal of the piston (32) of the air-tight adjustment group (3) fails, causing the vacuum pump to continuously generate a pressure difference, so that the gas-water separator (1 ) inside the water level continues to rise, the buoy (12) will continue to rise, so that the connecting rod group (13) touches the breaking rod (24), and hits the gas sound ball (22), and the The external atmosphere can flow into the gas-water separator (1) through the groove (231) and the through hole (111) provided on the periphery of the passage (213) and the buoyancy seat (23) by the outer cover (26) air hole (261), and The air sound is formed (this is the sound formed because the pressure difference is large and the gap is small, resulting in a fast air flow rate), to achieve the warning effect of breaking the vacuum, as shown in the third figure.

When the air-water separator (1) is applied in a positive pressure state, please refer to the fourth and fifth diagrams, because the air-sound ball (22) has no external force constraints, the water pressure inside the air-water separator (1) will go to the air. The direction of the sound ball (22) overflows, so when the water level pushes up the buoy (12) and continues to rise, the connecting rod group (13) will move upwards to push away the described breaking rod (24). Because the internal pressure of the gas-water separator (1) is greater than the external atmospheric pressure, through the design of the buoyancy seat (23), the buoyancy seat (23) is pushed up, and the air-tight gasket (25) on the end face is used to close the passage ( 213), and prevent the water pressure inside the air-water separator (1) from spraying out from the channel (213), so that the water pump can still operate normally under the situation of extreme vacuum in the positive pressure state.

Please refer to the sixth to seventh figures, it is worth mentioning that there is a screw hole (232) in the center of the buoyancy seat (23), and the corresponding screw hole (232) of the breaking rod (24) is provided with mutual locking The threaded section (241), and then let the airtight gasket (25) correspondingly nest on the end surface of the buoyancy seat (23), and the end surface is provided with a dovetail groove (233) for the airtight gasket (25) Assembled, it can stabilize the positioning of the nested group; in addition, in order to make it convenient to make the dovetail groove (233), a concave portion (230) is specially provided on the end surface of the buoyancy seat (23), and a ring on the inner side of the concave portion (230) A first dovetail groove (233A) is formed on the edge, and an embedding (242) is provided at the position corresponding to the recess (230) of the breaking rod (24), and the outer ring edge of the embedding (242) corresponds to the A second dovetail groove (242A) is formed at the first dovetail groove (233A), and the first and second dovetail grooves (233A), (242A) form a dovetail groove for nesting the airtight gasket (25) (233).

However, the aforementioned embodiments or drawings do not limit the product structure or usage of the present invention, and any appropriate changes or modifications by those with ordinary knowledge in the technical field shall be considered as not departing from the patent scope of the present invention.
