Description

Technical Field

[0001] The invention relates to the technical field of drinking water equipment, and in particular to a balancing box and a pipeline machine. Background Art

[0002] At present, the heat storage pipeline machine using the Venturi effect has been widely used in the market because of its low cost and simple design. This type of pipeline machine generally adopts a balance box structure, which plays a vital role in the operation of the pipeline machine. On the one hand, the balance box needs to be quickly connected to the hot water tank at the end of water intake, so that the liquid level at the water nozzle drops, thereby effectively preventing dripping and leakage; on the other hand, the balance box also needs to balance the pressure inside the equipment to avoid equipment damage caused by pressure imbalance and ensure safety of use. At the same time, when the pipeline machine is discharging water, the balance box needs to be able to disconnect from the hot water tank in time to prevent air from entering the internal pipeline, otherwise it may cause problems such as poor water discharge and water explosion, and in severe cases may even cause safety hazards such as scalding. Therefore, the timely opening and effective sealing of the balance box are crucial to the normal operation of the Venturi effect heat storage pipeline machine.

[0003] However, most of the sealing solutions for the balance boxes of such pipeline machines on the market currently use a small plastic ball and a rubber sealing ring in the balance box for sealing. During the water intake process, a negative pressure will be formed at the water outlet of the balance box, which will adsorb the small ball on the sealing ring. However, due to the relatively small negative pressure and limitations in processing accuracy, this combination method often cannot achieve complete sealing. In order to compensate for this defect, a portion of water above the contact surface must be retained inside the balance box after the two are in contact to prevent air from entering. However, this solution has the following defects:

[0004] First, the plastic ball is small in size and can only sink a limited distance below the water surface when floating, which means that after contacting the sealing ring, very little water remains in the tank. Once all the water is sucked into the hot water tank through the tiny gap, the sealing effect will be lost, which is also the main reason why the pipeline machine often explodes suddenly after a certain period of water discharge.

[0005] Secondly, the sealing ring is small in size and needs to be pressed into the bottom of the balance box for fixing. This process often requires the use of tools, which makes installation difficult. In addition, after installation, the small hole in the middle of the sealing ring is easily squeezed and deformed, further affecting the matching gap between the ball and the ball, thereby reducing the sealing effect. Summary of the invention

[0006] In order to solve the above problems, the present invention provides a balance box and a pipeline machine. The present invention optimizes the structure of the balance box and the installation method in the pipeline machine, aiming to achieve the effect of no dripping during use and long-term water discharge without water explosion. At the same time, by adjusting the size and height of the float, the amount of water remaining inside the balance box during sealing can be controlled, which not only avoids the problem of too little residual water affecting the sealing effect, but also prevents the problem of too much water causing the liquid level at the water nozzle to drop insufficiently after the water is taken, thereby causing dripping and leakage.

A side of the sealing protrusion facing the sealing protrusion is used to abut against the limiting protrusion, and the sealing protrusion cooperates with the second outlet pipe. When the sealing protrusion abuts against the limiting protrusion, the sealing protrusion extends into the second outlet pipe to block the second outlet pipe.

[0011] In one embodiment of the present invention, it further comprises a cover plate disposed on the balancing box body, wherein the cover plate is provided with a first outlet pipe communicating with the interior of the balancing box body, and the first outlet pipe is communicated with the outside.

[0012] In one embodiment of the present invention, the interior of the balance box body includes a first space and a second space that are interconnected; the guide limit assembly includes a first guide limit assembly and a second guide limit assembly; the first guide limit assembly is fixedly connected to the cover plate and is located in the first space, and the second guide limit assembly is fixedly connected to the balance box body and is located in the second space; the first guide limit assembly includes a first accommodating space, and the second guide limit assembly includes a second accommodating space, and the first accommodating space, the second accommodating space, and the second outlet pipe are connected in sequence.

[0014] In one embodiment of the present invention, the first accommodating space, the second accommodating space, and the second outlet pipe are coaxial.

[0015] In one embodiment of the present invention, the sealing protrusion is a hemispherical structure, and the sealing protrusion of the hemispherical structure can extend into the second outlet pipe to seal it.

[0016] In one embodiment of the present invention, the mounting post of the sealing member extends into the mounting hole of the float and is interference fit with the mounting hole.

[0017] In a second aspect, the present invention provides a pipeline machine, comprising a balance tank as described above, the pipeline machine also comprising a pipeline machine body, and a hot water tank, a first pipeline, a Venturi tee, a second pipeline and a third pipeline installed in the pipeline machine body; the first pipeline, the second pipeline and the third pipeline are respectively connected to the three openings of the Venturi tee; the first pipeline is connected to an external water supply, the third pipeline is connected to the second outlet pipe of the balance tank, the second pipeline is connected to the bottom of the hot water tank, the top of the hot water tank is connected to a water outlet pipe, and the hot water in the hot water tank flows out through the water outlet pipe.

[0020] Beneficial effects of the present invention:

[0021] The present invention provides a balance tank and pipeline machine, wherein the first pipeline is used to enter cold water, and the cold water flows through the first pipeline, the venturi tee, and the second pipeline in sequence to enter the bottom of the hot water tank, and pushes the hot water in the hot water tank out from the outlet pipe. Due to the different temperatures and densities of the cold water when entering the hot water tank, the cold water will be deposited at the bottom of the hot water tank to push the hot water out, and at the same time, a baffle is set at the cold water inlet in the hot water tank, that is, a baffle is set at the connection between the second pipeline and the bottom of the hot water tank, to prevent the cold water from flowing directly upward when entering and causing heat convection. In addition, if the balance tank is not sealed tightly when the cold water enters, the cold water mixes with the balance tank and the air in the third pipeline and enters the hot water tank together, a large number of steam drums will be generated in the hot water tank, forming a violent heat convection, which will cause the water temperature to drop rapidly. Therefore, the present invention improves the sealing effect through the design of the sealing structure between the seal and the second outlet pipe, and can effectively solve the problem of the balance tank being not sealed tightly, thereby avoiding the generation of a large number of steam drums in the hot water tank to form a violent heat convection, and avoiding causing the water temperature to drop rapidly. Therefore, the present invention optimizes the structure of the balance box and its installation method in the pipeline machine, aiming to achieve the effect of no dripping during use and no water explosion during long-term water discharge. At the same time, by adjusting the size and height of the float, the amount of water remaining inside the balance box during sealing can be controlled, which not only avoids the problem of too little residual water affecting the sealing effect, but also prevents the problem of too much water causing the liquid level at the water nozzle to drop insufficiently after the water is taken, thereby causing dripping and leakage.

[0044] In some embodiments, the interior of the balance box body 12 includes a first space 124 and a second space 125. The first space 124 and the second space 125 are interconnected and form an L-shaped structure. The first guide limit assembly 112 of the cover plate 11 extends into the first space 124. The balance box body 12 is fixedly connected to the second guide limit assembly 123 located in the second space 125. The first guide limit assembly 112 and the second guide limit assembly 123 are coaxial.

[0045] In some embodiments, the second guide limit assembly 123 includes a plurality of second arc plates 1231 arranged in a ring shape, a second gap 1234 is formed between adjacent second arc plates 1231, a plurality of second arc plates 1231 are combined to form a second accommodating space 1233, and a second reinforcing plate 1232 is fixedly connected between the second arc plates 1231 and the balance box body 12.

[0046] In this embodiment, the second accommodating space 1233 can be connected to the interior of the balance box body 12 through the second gap 1234, and the movement of the float 13 and the seal 14 is guided and limited by a plurality of second arc plates 1231 arranged in a ring, so that the float 13 and the seal 14 can move in the second accommodating space 1233 formed by the plurality of second arc plates 1231; the second arc plate 1231 and the balance box body 12 are connected and fastened by the second reinforcing plate 1232.

[0048] In some embodiments, a second outlet pipe 121 connected to the interior of the balancing box body 12 is provided at one end of the second space 125 away from the first space 124, and the second outlet pipe 121 is connected to the second accommodating space 1233; a movable float 13 and a seal 14 are provided in the first accommodating space 1123 and the second accommodating space 1233, and the seal 14 is located between the float 13 and the second outlet pipe 121.

[0049] In this embodiment, a second outlet pipe 121 is provided at the bottom of the balancing tank body 12, and the second outlet pipe 121 is connected to the negative pressure port of the venturi tee 2, and the venturi tee 2 is connected to the hot water tank 3. The first space 124 in the balancing tank body 12 is provided with the first guide limiter assembly 112 of the float 13, and the second space 125 in the balancing tank body 12 is provided with the second guide limiter assembly 123 of the float 13. The first guide limiter assembly 112 has a first accommodation space 1123, and the second guide limiter assembly 123 has a second accommodation space 1233, and the float 13 and the seal 14 can move up and down in the first accommodation space 1123 and the second accommodation space 1233.

[0050] In some embodiments, a limiting protrusion 1211 cooperating with the sealing member 14 is provided on a side of the second outlet pipe 121 facing the second accommodating space 1233 .

[0051] In some embodiments, the seal 14 includes a mounting column 143, and a sealing boss 141 fixedly connected to one side of the mounting column 143, a sealing protrusion 142 is fixedly connected to the side of the sealing boss 141 away from the mounting column 143, and a side of the sealing boss 141 facing the sealing protrusion 142 is used to abut against a limiting protrusion 1211 of the second outlet pipe 121, and the sealing protrusion 142 cooperates with the second outlet pipe 121. When the sealing boss 141 abuts against the limiting protrusion 1211 of the second outlet pipe 121, the sealing boss 141 extends into the second outlet pipe 121 to seal the second outlet pipe 121.

[0052] Furthermore, the sealing protrusion 142 may be a hemispherical structure, and the sealing protrusion 142 with a hemispherical structure may extend into the second outlet pipe 121 to seal it.

[0053] In some embodiments, the float 13 includes a float body 131 and a mounting portion 133 fixedly connected to the float body 131, a cavity 135 is formed between the float body 131 and the mounting portion 133, a mounting hole 132 is formed inside the mounting portion 133, and a groove 134 is provided at one end of the float body 131 close to the mounting hole 132; the mounting column 143 of the seal 14 extends into the mounting hole 132 of the float 13 and has an interference fit with the mounting hole 132; a portion of the sealing boss 141 is located in the groove 134 and abuts against the float body 131.

[0054] In this embodiment, the float 13 can be a long cylindrical structure, and the cavity 135 arranged inside the float 13 facilitates the float 13 to float up, ensuring the response sensitivity when opening; at the same time, by adjusting the height of the float 13 and the size of the cavity 135, the distance that the float 13 sinks below the water surface when floating can be controlled, so that the residual water amount in the balance box 1 during sealing can be conveniently controlled, and the sealing effect is better.

[0055] Compared with other balance boxes, the seal 14 of the balance box 1 provided by the present invention is installed in the float 13, so that it is not necessary to use tooling during installation, and it is more convenient to install and disassemble; and the balance box 1 forms a single seal by abutting the sealing boss 141 of the seal 14 with the limiting boss 1211 of the second outlet pipe 121; at the same time, the sealing boss 142 of the hemispherical structure can extend into the second outlet pipe 121, and cooperate with the second outlet pipe 121 to form a double seal, further enhancing the sealing effect. When the seal 14 is installed with the float 13, part of the sealing boss 141 is located in the groove 134 and abuts with the float body 131. At the same time, the installation column 143 of the seal 14 extends into the installation hole 132 of the float 13 and has an interference fit with the installation hole 132, avoiding the problem of a gap between the seal 14 and the installation hole 132 of the float 13 due to extrusion deformation during installation. Among them, the seal 14 can be made of softer materials such as food-grade rubber or silicone.

[0056] In addition, the present invention also provides a pipeline machine, including the above-mentioned balance tank 1, the pipeline machine also includes a pipeline machine body 8, and a hot water tank 3, a first pipeline 5, a Venturi tee 2, a second pipeline 6 and a third pipeline 7 installed in the pipeline machine body 8; the first pipeline 5, the second pipeline 6 and the third pipeline 7 are respectively connected to the three openings of the Venturi tee 2; the first pipeline 5 is connected to the external water supply, the third pipeline 7 is connected to the second outlet pipe 121 of the balance tank 1, the second pipeline 6 is connected to the bottom of the hot water tank 3, and the top of the hot water tank 3 is connected to the water outlet pipe 4, and the hot water in the hot water tank 3 flows out through the water outlet pipe 4.

[0057] When taking hot water from the hot water tank 3, the external water supply flows through the first pipeline 5, the Venturi tee 2, and the second pipeline 6, forming a negative pressure at the second outlet pipe 121 of the balance tank 3, sucking the float 13 and the seal 14, and the sealing boss 141 of the seal 14 abuts against the limiting protrusion 1211 of the second outlet pipe 121. At the same time, the sealing protrusion 142 of the hemispherical structure is deformed by the suction force and cooperates with the second outlet pipe 121 to improve the sealing effect, prevent the external air entering from the first outlet pipe 111 from entering the third pipeline 7 connected to the hot water tank 3, and ensure that the water column is good and does not explode. At the same time, no violent heat convection will be formed inside the hot water tank 3, slowing down the speed of water temperature drop, and improving the hot water making capacity and single hot water output of the equipment;

[0058] When water is taken from the hot water tank 3, the negative pressure of the Venturi tee 2 disappears. At this time, the liquid level in the water outlet pipe 4 is higher than the limiting protrusion 1211 of the balance tank 1. Under the influence of water pressure and buoyancy, the float 13 rises rapidly in the second accommodating space 1233 and the first accommodating space 1123. The balance tank 1 is connected with the hot water tank 3 through the Venturi tee 2. At this time, under the action of atmospheric pressure, the liquid level in the water outlet pipe 4 drops rapidly until it maintains the same horizontal position as the liquid level in the balance tank 3, thereby achieving the effect of balancing the internal pressure of the hot water tank 3 and preventing dripping and leakage at the water spout.

[0059] In some embodiments, the first space 124 of the balancing tank 1 is located above the hot water tank 3 , and the second space 125 of the balancing tank 1 is lower than the top surface of the hot water tank 3 .

[0060] In this embodiment, through the structural layout inside the above-mentioned pipeline machine, after the balance tank 1 is installed, it is ensured that the limiting protrusion 1211 of the balance tank body 12 is located below the top surface of the hot water tank 3, and the bottom surface of the balance tank bottom 1 is lower than the top surface of the hot water tank 3.

[0061] In some embodiments, a baffle is provided at the connection between the second pipeline 6 and the bottom of the hot water tank 3 .

[0062] In summary, the present invention provides a balance tank and pipeline machine, wherein the first pipeline 5 is used to inlet cold water, and the cold water flows through the first pipeline 5, the venturi tee 2, and the second pipeline 6 in sequence to enter the bottom of the hot water tank 3, and pushes the hot water in the hot water tank 3 out from the outlet pipe 4. Since the temperature and density of the cold water when entering the hot water tank 3 are different, the cold water will be deposited at the bottom of the hot water tank 3 to push the hot water out, and at the same time, a baffle is provided at the cold water inlet in the hot water tank 3, that is, a baffle is provided at the connection between the second pipeline 6 and the bottom of the hot water tank 3, to prevent the cold water from flowing directly upward when entering and causing heat convection. In addition, if the balance tank 3 is not sealed tightly when the cold water enters, causing the cold water to mix with the balance tank 3 and the air in the third pipeline 7 to enter the hot water tank 3, a large number of steam drums will be generated in the hot water tank 3, forming violent heat convection, which will cause the water temperature to drop rapidly. Therefore, the present invention improves the sealing effect through the design of the sealing structure between the seal 14 and the second outlet pipe 121, and can effectively solve the problem of poor sealing of the balance tank 3, thereby avoiding the generation of a large number of steam drums in the hot water tank 3 to form violent heat convection and avoid causing the water temperature to drop rapidly. Therefore, the present invention optimizes the structure of the balance tank 3 and its installation method in the pipeline machine, aiming to achieve the effect of no dripping during use and long-term water discharge without water explosion. At the same time, by adjusting the size and height of the float, the amount of water remaining inside the balance tank during sealing can be controlled, which not only avoids the influence of too little residual water on the sealing effect, but also prevents the problem of too much water causing the liquid level at the water nozzle to drop insufficiently after the water intake is completed, thereby causing dripping and leakage.
