Description

Gas-water separator

This creation relates to a pumping device, in particular to a gas-water separator with sensitive operation.

When carrying out projects such as digging wells, mining, digging tunnels or burying pipelines, it is common to encounter groundwater gushing and standing water, which will hinder the progress of construction. On-site staff often use pumps to extract groundwater to ensure that the project can continue; In addition, pumps are also often used to eliminate drainage in basements or low-lying areas, and even pumps are often used in ship drainage.

When the pump is pumping, it first sucks air with a vacuum pump to generate negative pressure, draws water into the water pump, and the air sucked by the vacuum pump passes the air-water separator installed in the pump to separate the water in the air. Enter the vacuum pump to prevent air containing moisture from entering the vacuum pump and causing damage to the vacuum pump.

An existing gas-water separator, as disclosed in the Chinese Patent No. CN 203944230U Utility Model, includes a float and an on-off valve device in the interior. Wherein, the buoy is located inside the gas-water separator and can rise or fall with the water drawn into the gas-water separator. The interlocking on-off valve device is located above the buoy and includes an upper valve port seat and a lower valve port seat fixedly arranged inside the gas-water separator, an upright seat passing through the upper valve port seat and a lower valve port seat. A push rod, a ball plug located above the push rod and capable of closing the upper valve port seat, and a lower valve plug coupled to the lower end of the push rod and capable of closing the lower valve port seat. When the buoy rises with the water level, the buoy can abut against the lower valve plug, push the lower valve plug to move upward to close the lower valve port seat, and the push rod moves upward with the lower valve plug and pushes up the The ball plug opens the upper valve port seat; conversely, when the buoy descends with the water level, the upper valve port seat is opened and the lower valve port seat is closed.

However, due to the existing gas-water separator, the push rod and the pontoon of the linked on-off valve device are two separate components without a combination. Therefore, when the buoy is caused to rise, it is often the case that the buoy fails to reliably abut the lower valve plug. In addition to the fact that the lower valve plug cannot be actuated immediately and surely with the movement of the buoy, it also affects the operation of the ball plug, thereby affecting the effectiveness of the existing gas-water separator in separating air and water. It can be known from the foregoing that the existing gas-water separator still has room for improvement and improvement in the structural design of the pontoon and the linked on-off valve device.

In order to solve the existing gas-water separator, the push rod and the float of the linked opening-closing valve device are two components that have no connection relationship, so that the lower valve plug and the ball plug cannot act instantly and surely with the movement of the float, The result is poor separation of air and water.

As shown in Figures 4 and 5, when water is pumped into the water tank T by a water pump equipped with a gas-water separator of the present creation, the vacuum pump connected to the creation is also operated at the same time, and the vacuum pump passes through the exhaust pipe H draws air out of this creation. At this time, the upper ball plug 63 abuts against the stop convex portion 412 of the upper valve plug 41 and covers the communication hole 413 provided in the upper valve plug 41, and the upper ball plug 63 pushes down against the stop convex The portion 412 allows the stopper protrusion 412 to stop at the tapered section 313 of the valve passage 31 above the upper valve seat 30. Because the upper ball plug 63 covers the communication hole 413 and the stopper protrusion 412 stops at The tapered section 313 prevents the air chamber 21 of the air-water path piece 20 from communicating with the exterior of the creation.

As shown in FIG. 2, FIG. 3 and FIG. 6, the vacuum pump continues to run and the air chamber 21 cannot communicate with the exterior of the creation, so that the pressure in the air chamber 21 is lower than the water tank T. The moisture-laden air from the water tank T enters the floating member compartment 11 of the suction bucket 10 and the lower valve passage 51 of the lower valve seat 50. The moisture-laden air moves the lower valve plug of the lower valve plug assembly 70. 71 is pushed up and enters the air chamber 21 through the lower valve passage 51, and air with moisture enters the air chamber 21, and then enters the separation chamber 12 of the suction bucket 10 through the connecting passage 22 of the air-water path piece 20, Moisture is left in the separation chamber 12, and the dry air enters the second auxiliary air chamber 23B of the air-water path member 20 through the filter F, and is extracted from the original creation through the exhaust pipe H.

As shown in FIG. 7 and FIG. 8, as the vacuum pump continues to operate, the pressure in the air chamber 21 becomes smaller and smaller, and the water pumped into the water tank T enters the floating member capacity through the joint 13 of the suction bucket 10. In the chamber 11, the water level in the floating member container 11 gradually rises, and the floating member 62 of the interlocking opening-closing assembly 60 also moves upward by the action of buoyancy, and the interlocking rod 61 and the consolidation of the floating member 62 are consolidated. The lower ball plug 64 on the linkage lever 61 also moves upward. The lower ball plug 64 abuts against the tapered recess 511 of the valve passage 51 below the lower valve seat 50 and closes the lower valve passage 51. At the same time, the upper ball plug 63 fixed to the link lever 61 also moves upward with the link lever 61, and the upper ball plug 63 no longer abuts against the stopper protrusion 412 to allow air outside the creation to pass through The communication hole 413 enters the air chamber 21. As shown in FIG. 9, then, the upper valve plug 41 that is no longer pushed by the upper ball plug 63 is pushed up by the compression spring 42 of the valve plug assembly 40, and the stop protrusion 412 is also pushed away from the The tapered section 313 does not cover the upper valve passage 31 any more, and the air outside the original creation further enters the air chamber 21 through the gap between the upper valve plug 41 and the upper valve seat 30.

The air in the floating member container 11 is continuously drawn out, and the air outside the original creation enters the air chamber 21 through the upper valve seat 30, so that the pressure of the air chamber 21 is greater than the pressure in the floating member container 11. At this time, the lower valve plug 71 is pressed against the lower valve seat 50 again and covers the lower valve passage 51. The air outside this creation is continuously drawn into the separation chamber 12 through the air chamber 21, so the pressure in the separation chamber 12 is greater than the pressure in the floating member chamber 11, and the water and The sucked-in external air will flow back to the floating member container 11 through the one-way valve device C, passing through the first auxiliary air chamber 23A of the air-water path member 20 and the communication hole 24. At this time, the pressure of the floating member storage chamber 11 is greater than the pressure in the water tank T again. The water in the floating member storage chamber 11 flows back to the water tank T, and the linkage opening and closing assembly 60 moves downward. This creation returns to FIG. 5 again. status.

In the existing gas-water separator, the push rod of the on-off valve device and the buoy are two separate components, which causes the buoy to rise, often because the buoy fails to actually abut the lower valve plug, which causes the The lower valve plug cannot be actuated immediately and surely with the movement of the buoy, and at the same time, it also affects the operating condition of the ball plug. The linked opening-closing assembly 60 of the present creation connects the floating member 62, the upper ball plug 63 and the lower ball plug 64 with the link lever 61. Therefore, when the floating member 62 moves up and down with the water level of the floating member container 11, the upper ball plug 63 and the lower ball plug 64 can control the upper valve seat in real time as the floating member 62 moves. 30 and the lower valve seat 50 are opened and closed. Therefore, compared with the existing gas-water separator, the linked opening-closing assembly 60 of the present invention is more sensitive in operation and has better performance in separating air and water.

Furthermore, the present invention adds the upper valve plug assembly 40 in the upper valve seat 30, so that the upper valve passage 31 of the upper valve seat 30 can pass through the upper ball plug 63 of the linkage opening and closing assembly 60, and the The upper valve plug assembly 40 controls opening and closing, so that the upper valve passage 31 can be opened and closed in stages.
