Description

Technical Field

[0001] The utility model relates to the technical field of cabin drainage, in particular to a diverter of a drying system. Background Art

[0002] During the voyage of a ship, water may accumulate in the cabin due to various reasons. If the accumulated water is not discharged for a long time, it will cause hull corrosion, cargo damage, etc. In serious cases, it may even affect the stability and navigation safety of the ship.

[0003] Existing cabins are generally equipped with water pumps to suck out the accumulated water. However, there are many cabins in the ship hull. If each cabin is equipped with an independent water pump, the cost will increase and the control system will become complicated. Therefore, at present, a total water suction system is generally integrated into the hull, and then the water inlet end of the water suction system is connected to the water pump of each cabin through a diverter. A solenoid valve is set in the diverter to realize the on-off control. When water accumulates in a cabin, the corresponding waterway is opened by controlling the diverter to suck out and discharge the water in time.

[0004] Since water will accumulate in different cabins at different times and to different degrees during the voyage, the drying system is usually in a normally open state, and its suction will continue to act on the diaphragm of the unopened solenoid valve in the diverter. At the same time, the drying system may increase or decrease the suction according to the number of cabins that need to be drained, that is, the negative pressure generated will increase or decrease. When the suction / negative pressure of the drying system continues to increase, the solenoid valve that is about to be opened may not be opened due to excessive suction / negative pressure, resulting in the corresponding cabin being unable to drain.

[0034] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0035] refer to Figures 1 to 5 As shown, the utility model discloses a flow divider of a drying system, comprising a flow divider housing 1, a diaphragm seat 2, a diaphragm 3, a solenoid valve 4, a first spring 5 and a circuit board 6;

[0036] A water outlet channel 11 and a plurality of water inlet channels 12 are provided in the diverter housing 1, and each water inlet channel 12 is connected to the water outlet channel 11 through a water hole 13;

[0037] Each water hole 13 is provided with a diaphragm seat 2; a pilot hole 21 opposite to the water hole 13 is provided on the diaphragm seat 2, and a diaphragm 3 for movably blocking the water hole 13 is installed on the side of the diaphragm seat 2 facing the water hole 13;

[0038] Each diaphragm seat 2 is provided with a solenoid valve 4; the solenoid valve 4 is fixedly installed in the diverter housing 1, and forms a pilot cavity a connected to the pilot hole 21 with the diaphragm 3; the iron core 41 of the solenoid valve 4 blocks the pilot hole 21 when it is not powered;

[0039] The first spring 5 is disposed between the solenoid valve 4 and the diaphragm seat 2, and is used to provide elastic force so that the diaphragm seat 2 drives the diaphragm 3 to block the water hole 13;

[0040] The circuit board 6 is electrically connected to each solenoid valve 4 to realize the switch control of each solenoid valve 4 (of course, the circuit board 6 is not necessary, and each solenoid valve 4 can also be directly controlled by the suction system through wired / wireless methods, and the circuit board 6 is only an example of one control method).

[0041] Through the above scheme, the utility model arranges a diaphragm seat 2 with a pilot hole 21 between the solenoid valve 4 and the water hole 13, and a pilot cavity a is formed between the diaphragm 3 on the diaphragm seat 2 and the solenoid valve 4. When a cabin needs to be drained, it is only necessary to open the corresponding solenoid valve 4 to first drain the air in the pilot cavity a through the pilot hole 21, so that the diaphragm 3 is separated from the water hole 13 under the action of pressure, thereby connecting the water outlet channel 11 with the water inlet channel 12 connected to the cabin, and then using the suction to drain the water. The suction force of system b is used to pump water; compared with the prior art in which the solenoid valve 4 directly blocks the water hole 13, the solenoid valve 4 in the present invention only needs to control the opening and closing of the pilot hole 21. The aperture of the pilot hole 21 is much smaller than the water hole 13, so that the force-bearing area at the end of the iron core 41 is smaller, and the force of the suction force / negative pressure of the suction system b acting on the end of the iron core 41 of the solenoid valve 4 is also relatively small. The solenoid valve 4 can easily open the pilot hole 21, and finally open the water hole 13, ensuring stable drainage.

[0042] Specific embodiments of the present utility model are shown below.

[0043] The above-mentioned splitter housing 1 is designed to be a detachably connected base 1a and upper cover 1b; the base 1a is provided with an upwardly opening mounting cavity 14, the water inlet channel 12 and the water hole 13 are both connected to the bottom of the mounting cavity 14, and the water outlet channel 12 is arranged parallel to the bottom of the mounting cavity 14; the upper cover 1b covers the opening of the mounting cavity 14; the solenoid valve 4 and the circuit board 6 are both fixedly installed in the mounting cavity 14. If the water hole 13 is arranged at the bottom of the mounting cavity 14, the iron core 41 of the solenoid valve 4 is arranged in the up-down direction, and when the solenoid valve 4 is closed, the iron core 41 can be reset downward by its own weight.

[0044] Furthermore, the solenoid valve 4 comprises a valve core sleeve 42 for telescopically cooperating with the iron core 41, a second spring 43 disposed in the valve core sleeve 42 and abutting against the iron core 41, and a coil 44 sleeved on the valve core sleeve 42 and connected to the electric core of the circuit board 6. When the solenoid valve 4 is closed, the weight of the iron core 41 and the elasticity of the second spring 43 can be used to realize downward reset.

[0045] Secondly, the valve core sleeve 42 is provided with a movable cavity 421 on the side facing the water hole 13, and the diaphragm seat 2 is movably fitted in the movable cavity 421. The opening periphery of the movable cavity 421 presses the periphery of the diaphragm 3 against the bottom of the installation cavity 14, so that the solenoid valve 4 can fix the diaphragm 3 and the diaphragm seat 2 after installation, without the need for additional structures / accessories to fix the diaphragm 3.

[0046] In addition, an iron core head 45 made of rubber material is also provided at the end of the iron core 41 , and the iron core head 45 is used to seal the pilot hole 21 to ensure a sealing effect.

[0047] The diaphragm seat 2 is provided with a through hole 22 opposite to the water inlet channel 12, and the through hole 22 is connected to the pilot chamber a. The through hole 22 can be provided to replenish fluid or gas into the pilot chamber a, especially when the suction system b stops working and no longer generates suction / negative pressure, the pressure balance inside and outside the diaphragm 3 can be achieved by replenishing fluid or gas, ensuring that the diaphragm 3 can be accurately reset and the water hole 13 can be blocked when the solenoid valve 4 is closed, avoiding the situation where the water hole 13 cannot be closed due to the high pressure at one end of the water inlet channel 11 when the suction system b stops working, and the equipment downstream of the diverter is protected.

[0048] Furthermore, the first spring 5 is a tower spring, one end of which is bent to form a through-hole needle 51 that penetrates the through-hole 22 , thereby preventing the through-hole 22 from being blocked by tiny debris.

[0049] Secondly, a limiting ring 23 for the small end of the tower spring to be sleeved is provided on the side of the diaphragm seat 2 facing the solenoid valve 4, and the pilot hole 21 is provided on the axis of the limiting ring 23; the large end of the tower spring abuts the solenoid valve 4, and the iron core 41 of the solenoid valve 4 is passed through the tower spring and blocks the pilot hole 21.

[0050] The utility model also includes a quick-install assembly 7 arranged at the outlet of the water outlet channel 11 or the inlet of the water inlet channel 12; see Figure 2 and Figure 4The quick-install assembly 7 includes a fixing ring 71, a limiting tube 72 and a C-shaped buckle 73; the outer peripheral surface of the fixing ring 71 is matched with the inner wall of the water outlet channel 11 or the water inlet channel 12, and the inner end of the inner ring wall is provided with a relief slope 711; the limiting tube 72 can be passed through by a water pipe (i.e., the water inlet pipe 10 or the water outlet pipe 60 described below), and one end of the limiting tube 72 is composed of a plurality of elastic arms 721, which are passed through the fixing ring 71 and can be deformed outwardly along the radial direction of the fixing ring 71 at the relief slope 711, so that the water pipe can smoothly pass through the limiting tube 7 2, and the outer side of the end of the elastic arm 721 is provided with a matching bevel 722; the circumference of the other end of the limiting tube 72 is provided with a limiting flange 723; the C-shaped buckle 73 is sleeved on the limiting tube 72, and its two sides respectively abut the limiting flange 723 and the fixing ring 71, so that the matching bevel 722 fits on the giving bevel 711, preventing the limiting tube 72 from axially moving in the fixing ring 71, so that the water pipe, the limiting tube 72, the fixing ring 71 and the inner wall of the water outlet channel 11 / water inlet channel 12 are tightly matched, achieving the purpose of preventing from falling off. In order to prevent the water pipe connected to the diverter from being disconnected due to high pressure, the current technology adopts the threaded connection method. Although the structure is relatively stable, it is troublesome to disassemble and assemble. The utility model can quickly disassemble and assemble the water pipe through the quick-fit assembly 7, and the water pipe and the diverter are relatively fixed by the friction force of the tight fit.

[0051] Furthermore, the peripheral surface of the fixing ring 71 and the inner wall of the elastic arm 721 are both provided with protrusions, which can increase the friction between the corresponding matching surfaces and make the structure more stable.

[0052] See also Figure 5 , the working principle of the utility model is:

[0053] 1) The suction system b continues to work, the air in the water outlet channel 11 is sucked away to generate negative pressure, and when the solenoid valve 4 is not energized, the diaphragm 3 is tightly fitted at the water hole 13 to block the water hole 13;

[0054] 2) When a cabin needs to pump out accumulated water, the corresponding solenoid valve 4 is opened. After the coil 44 of the solenoid valve 4 is energized, its iron core 41 is attracted upward, so that the pilot hole 21 is opened, the air in the pilot chamber a is sucked out, and the internal pressure of the pilot chamber a is reduced. The diaphragm 3 is pushed upward under the action of the internal and external pressure difference, so that the water hole 13 is opened, and then the water outlet channel 11 is connected with the water inlet channel 12. The accumulated water in the cabin is sucked into the suction system b through the pipeline-water inlet channel 12-water hole 13-water outlet channel 11.

[0055] See also Figure 6In the actual application scenario of the utility model, each water inlet channel 12 of the diverter is connected to the cabin through the water inlet pipe 10, the filter 20 and the universal tube 30 (which can also be a straight pipe). The upper end of the universal tube 30 is fixed by a fixing frame 40, and a counterweight block 50 is provided at its lower end so that the lower end of the universal tube 30 can be close to the floor of the cabin to ensure the suction effect; the water outlet channel 11 of the diverter is connected to the water inlet of the drying system b through the water outlet pipe 60, and finally the accumulated water is discharged from the water outlet 70 of the drying system b; in addition, the power cord 80 of the diverter is connected to the drying system b, and is powered by the drying system b.
