The working hole 3 is horizontally arranged on the valve body 5.
When the control valve is used, the control valve is installed on a lifter, the floating assembly 14 is arranged in the lifter, the working hole 3 is connected with the vacuum interface valve through a pipeline, the negative pressure hole 1 is externally connected with a vacuum source, and the emptying hole 8 is communicated with the external atmosphere.
Further, the top of the connecting cavity is provided with a magnetic ring 2 which is concentric with the negative pressure hole 1. The top of the connecting cavity is provided with a sealing ring 6 concentric with the negative pressure hole 1, and the sealing ring 6 is arranged below the magnetic ring 2, so that the magnetic bead 7 has better sealing property when the negative pressure hole 1 is blocked. When the power of the vacuum source is unstable, the sum of the suction force of the negative pressure hole 1 on the magnetic bead 7 and the magnetic force between the magnetic bead 7 and the magnetic ring 2 is greater than the gravity of the magnetic bead 7, so that the magnetic bead 7 moves upwards to block the sealing ring 6, the working hole 3 is communicated with the emptying hole 8, and the vacuum interface valve is closed.
Further, the triggering assembly comprises a sliding tube 10 and a sliding rod 13 inserted into the sliding tube 10 in a sliding mode, two ends of the sliding tube 10 are arranged in a sealing mode, the sliding tube 10 is installed in the guide tube 11 in a sliding mode, the sliding rod 13 penetrates out of the bottom end of the sliding tube 10 in a sliding mode and penetrates through the base 15 to be connected with the floating assembly 14, and the magnetic block 9 is installed at the top end of the sliding tube 10. The top end of the sliding rod 13 is screwed with a limit nut 12. Through the cooperation of slide tube 10 and slide bar 13, can adjust the trigger stroke of trigger assembly to adjust the liquid level difference between high liquid level and the low liquid level. After the sliding tube 10 ascends to press the magnet 9 against the emptying hole 8, the sum of the magnetic force between the magnet 9 and the magnetic bead 7 and the vacuum attraction force between the magnet 9 and the emptying hole 8 is larger than the sum of the gravity of the sliding tube 10 and the gravity of the magnet 9.
An operation hole is formed in the sliding pipe 10, and a limit nut 12 is conveniently mounted on the sliding rod 13 during assembly.
Specifically, the top end of the guide pipe 11 is provided with a sealing plate 4, and the emptying hole 8 is concentrically arranged on the sealing plate 4. The floating component 14 is a floating ball, and may be other objects capable of floating on the water surface, which is not limited herein.
The base 15 is round platform form, and inside is the uncovered cavity structure that sets up in bottom, and the base 15 bottom border level is turned over outwards and is rolled over and form the go-between, evenly sets up threaded hole on the go-between, and the base 15 is connected with the lifting mechanism through the bolt of wearing to establish in the threaded hole.
The working principle is as follows:
the utility model discloses a control valve passes through the bolt and installs on the lifting mechanism, and come-up subassembly 14 sets up in the lifting mechanism, and working hole 3 on the valve body is connected with the vacuum interface valve, the external vacuum source in negative pressure hole 1, evacuation hole 8 and external atmosphere intercommunication. As shown in fig. 2, when the waste water in the lifter is at a low liquid level, under the action of gravity, the sliding rod 13 drives the sliding tube 10 to be at the bottom of the guide tube 11, the magnet 9 is far away from the magnetic bead 7, so that the magnetic bead 7 is extremely small and negligible under the attraction of the magnet 9, at this time, the sum of the attraction of the negative pressure hole 1 and the magnetic force of the magnetic ring 2 on the magnetic bead 7 is greater than the gravity of the magnetic bead 7, so that the magnetic bead 7 moves upwards to block the sealing ring 6, the working hole 3 is disconnected with the negative pressure hole 1, the working hole 3 is communicated with the emptying hole 8.
When the waste sewage flows into the lifter under the action of gravity, and the liquid level in the lifter gradually rises, because the weight of the trigger assembly is smaller than the buoyancy of the floating ball 14, the floating ball 14 and the sliding rod 13 firstly go up linearly under the action of the buoyancy, then after the limit nut 12 at the top of the sliding rod 13 contacts the top of the sliding pipe 10, the floating ball 14 jacks up the sliding pipe 10 to continue going up linearly until the magnet 9 arranged on the sliding pipe 10 contacts the sealing plate 4 tightly pressed between the valve body 5 and the guide pipe 11, and the emptying hole 8 on the sealing plate 4 is blocked, as shown in fig. 3. At this time, the sum of the magnetic force between the magnet 9 and the magnetic bead 7 and the gravity of the magnetic bead 7 is larger than the sum of the magnetic force between the magnetic bead 7 and the magnetic ring 2 and the vacuum suction force of the negative pressure hole 1 to the magnetic bead 7, so that the magnetic bead 7 descends and clings to the sealing plate 4, the working port 3 and the negative pressure hole 1 are communicated, the vacuum interface valve is opened, and the sewage in the lifter is sucked to the vacuum sewage tank.
In the process that sewage in the lifter is pumped to the vacuum sewage tank, the liquid level in the lifter gradually drops. At this time, the sum of the magnetic force between the magnet 9 and the magnetic bead 7 and the vacuum attraction between the magnet 9 and the emptying hole 8 is larger than the sum of the gravity of the sliding tube 10 and the gravity of the magnet 9, so the floating ball 14 and the sliding rod 13 firstly descend linearly under the action of gravity until the limit nut 12 at the top of the sliding rod 13 contacts the bottom of the sliding tube 10, at this time, the gravity of the whole trigger part is larger than the sum of the magnetic force between the magnet 9 and the magnetic bead 7 and the vacuum attraction between the magnet 9 and the emptying hole 8, so the whole trigger part descends, the magnet 9 leaves the sealing plate 4, the magnetic force between the magnet 9 and the magnetic bead 7 is gradually reduced, when the sum of the magnetic force of the magnetic bead 7 and the magnetic force of the magnetic ring 2, which is subjected to the suction force of the negative pressure hole 1, is larger than the sum of the gravity of the magnetic bead 7 and the magnetic force between, the working hole 3 and the evacuation hole 8 are communicated with each other, and the vacuum interface valve is closed.
To sum up, the utility model discloses a control valve simple structure is reasonable, the cost of manufacture is low, need not the power consumption, dependable performance, long service life. The control valve of the invention adopts mechanical structure cooperation, controls the opening or closing of the vacuum interface valve by completely depending on the water level in the lifter, does not need to depend on a circuit control system any more, and has very convenient installation and use and high reliability.
