The water inlet joint comprises three chambers, namely a first chamber 1, a second chamber 2 and a third chamber 3. The first chamber 1 communicates the water inlet with the second chamber 2. The second chamber 2 is communicated with the first chamber 1 and the water outlet. The cross-sectional area of the second chamber 2 in the direction of liquid flow is smaller than the first chamber 1. The water flow may exit the water inlet connection after passing through the first chamber 1 and the second chamber 2 in sequence. The third chamber 3 is connected to the first chamber 1 and the second chamber 2, respectively. The third chamber 3 has a partition 311, and the third chamber 3 is partitioned from and closed by the partition 311 from the first chamber 1. The third chamber 3 further has a blocking member 321, the third chamber 3 is separated from and sealed with the second chamber 2 by the blocking member 321, the third chamber 3 is filled with a conductive medium, the partition 311 can move towards the third chamber 3 or the first chamber 1, and the blocking member 321 can move towards the third chamber 3 or the second chamber 2 and seal or gradually open the second chamber 2. Because the conductive medium filled in the third chamber 3 can transmit pressure and is incompressible, when the partition 311 or the blocking member 321 moves, the blocking member 321 or the partition 311 at the other end will be driven to move correspondingly, thereby playing a role in linkage. The partition 311 is higher than the barrier 321 in the vertical direction. So that the liquid in the water inlet pipeline firstly contacts the blocking member 321 and then contacts the partition 311 when the water level rises. The restoring mechanism is disposed above the separating member 321, one end of the restoring mechanism is connected to the top of the separating member 321, and the other end of the restoring mechanism is connected to the inner side of the third chamber 3 directly above the separating member 321, so as to drive the separating member 321 to move upward. When the water inlet joint is used, the liquid level height of water flow in the water inlet joint is gradually increased along with the increase of water pressure, when the water pressure is gradually increased, water firstly passes through the bottom end of the blocking piece 321 in the second chamber 2, the blocking piece 321 moves upwards and compresses the spring 4 under the action of the water pressure, along with the upward movement of the blocking piece 321, the heights of the bottom of the second chamber 2 and the bottom of the blocking piece 321 are gradually increased, the cross section of the second chamber 2 is gradually increased, the flow rate of the water flow is gradually reduced, and the water flow rate is also stabilized in a relatively fixed range. Meanwhile, when the water pressure is too high, the water flows over the top of the water inlet joint and contacts the partition 311, at this time, because the cross-sectional area of the first chamber 1 along the water flowing direction is larger than that of the second chamber 2, the water flowing speed is smaller than that of the second chamber 2, the water pressure received by the partition 311 is larger than that of the second chamber 2, the partition 311 moves towards the third chamber 3, the gas in the third chamber 3 transmits the pressure to the blocking member 321, and the blocking member 321 is pushed to move downwards until the blocking member 321 descends to the bottom of the second chamber 2, so that the second chamber 2 is sealed to cut off the water flow, and the water pipe is protected. When the water pressure decreases, the spring 4 pulls up the blocking member 321.

The first connecting portion 31 has a cavity therein, the cavity is in communication with the opening, and the partition 311 is disposed in the cavity inside the first connecting portion 31 and partitions the cavities of the first chamber 1 and the first connecting portion 31 to prevent water in the first chamber from flowing into the cavity and prevent air in the third chamber from overflowing from the opening. The partition 311 may be close to or distant from the through opening in the vertical direction within the first connection portion 31. The water contacts the diaphragm 311 only when it is at the top of the water inlet connector, ensuring that the water inlet connector does not cut off the water flow when the water pressure is in the normal position.

As shown in fig. 1, the third chamber 3 includes a second connecting portion 32, the second connecting portion 32 is connected to the top end of the second chamber 2, a through hole is formed at the top end of the second chamber, and the second connecting portion 32 is communicated with the through hole. The blocking member 321 is disposed in the second connecting portion 32 and in the opening at the top of the second chamber, and is movable along the second connecting portion 32 and the opening in the vertical direction and extends out to the bottom end of the second chamber 2. Pass second cavity 2 top, come the whole second cavity 2 of shutoff through removing to second cavity 2 bottom, play the effect of switching the rivers.

As shown in fig. 1, the first connecting portion 31 has sliding grooves 312 at both ends thereof, and the partition plate 311 is engaged in the sliding grooves 312 and can slide up and down in the sliding grooves 312. The diaphragm 311 is movable up and down in the slide groove 312 by the water pressure through the slide groove 312.

As shown in fig. 1, the restoring mechanism is a spring 4, one end of the spring 4 is connected to the inner side of the third chamber 3, and the other end of the spring 4 is connected to the upper portion of the blocking member 321. The spring 4 has elasticity, and can pull the blocking member 321 to offset its own weight so that it does not fall off when the water pressure is normal, and can also pull the blocking member 321 when the water pressure is reduced after the water flow is cut off by the blocking member 321.

As shown in fig. 1, the blocking member 321 can be moved to make the lowest end flush with the top end and the bottom end of the second chamber 2, respectively. The movement range of the blocking member 321 is the height of the second chamber 2, and the water flow can be stabilized within a fixed range.

The third chamber 3 is filled with gas, and the gas is enclosed in the third chamber 3 by the partition 311 and the partition 321, respectively. The gas is selected as a conducting medium, the dead weight of the gas is small, and the incompressible pressure conducting effect is good under the normal condition. In other embodiments, other materials such as liquids may be used.

In the natural state of the spring 4, the lowermost end of the barrier 321 is located between the top and bottom ends of the second chamber 2. The blocking member 321 for ensuring the water inlet joint is located at the normal position when the water pressure is normal, and the blocking member 321 enables the water inlet joint to move upwards between the second chambers 2 to achieve the flow stabilizing effect when the water inlet joint is at the normal position.

The vertical liquid flow direction is set to meet the direction of increasing the height of the page after the increase of the liquid water pressure, so that the partition 311 and the blocking member 321 can move along the liquid ascending direction more conveniently.

As shown in fig. 1 to 3, the water inlet joint of the present embodiment is in a steady flow state in fig. 1, and the spring 4 is in a natural state, and the bottom end of the blocking member 321 is located between the second chambers 2. The water flow is now at a lower water pressure, lower level and not in contact with barrier 321. When the water pressure gradually rises, the water level gradually rises, and the water flow gradually rises from the position not in contact with the blocking member 321 in the drawing and contacts the blocking member 321, and at this time, the water pressure of the water flow is transmitted to the blocking member 321 and generates an upward thrust to the blocking member 321. The state that the elastic force of the spring 4 in fig. 1 is just balanced with the self weight of the blocking member 321 is broken, the blocking member 321 is pushed to move upwards, and the conductive medium is transferred to the partition 311 to push the partition 311 to descend to make room. When the water pressure is higher and higher, the horizontal plane is higher and higher, the blocking member 321 gradually rises to the maximum position, i.e. the position in fig. 2, at this time, the partition 311 is located at the lowest end of the sliding chute and is limited by the sliding chute, and the blocking member 321 rises to the top end of the second chamber 2. The second chamber 2 reaches a maximum opening. The water inlet joint reaches the maximum water pressure of a steady flow state. If the water pressure continues to rise, the liquid level will continue to rise to the position that is beyond the top end of the first chamber 1 and contacts the partition 311, and the water pressure received by the partition 311 is greater than the water pressure received by the blocking member 321, so the partition 321 will move upward and drive the blocking member 321 to descend until the state shown in fig. 3, and the blocking member 321 will completely seal the second chamber 2, thereby preventing the pipeline from being damaged by the over-pressurized water flow.
