Description

A horizontal foam liquid pressure storage tank and its assembly method Technical Field

[0001] This application relates to the field of fire protection equipment, and in particular to a horizontal foam liquid pressure storage tank and its assembly method. Background Technology

[0002] The pressure-type foam proportioning device mainly consists of a horizontal foam liquid pressure storage tank with a bladder and a PHY-type pressure proportioner based on the Venturi principle. When water in the system pipeline flows through the pressure-reducing orifice plate of the proportioner, a pressure difference is formed before and after the orifice plate. A portion of the water (3% or 6%) at the higher pressure point enters the tank through the inlet pipe of the foam tank, squeezing the bladder and forcing the foam liquid in the bladder through the outlet pipe of the foam tank to the low-pressure point of the proportioner to mix with water to form a foam mixture. The resulting foam mixture is then output to foam generating equipment (medium, low, and high expansion foam generators, foam guns, foam cannons, etc.) to mix with air to produce foam for fire extinguishing.

[0003] The pressure tank is a crucial component of the device. The current pressure tank consists of a tank body and a capsule. The tank body has an outlet and an inlet on its upper and lower sides, respectively. The capsule is fixed to the flanges at the inlet and outlet by a flange. A manhole is located on one side of the pressure tank. The capsule is integrally formed, and several cable ties are integrally formed on the outside of the capsule. Correspondingly, multiple lifting rings are welded to the upper side of the inner wall of the tank. During actual installation, the installers enter the tank through the manhole and manually tie the cable ties to the lifting rings.

[0004] The existing capsule installation requires installers to enter the tank, which places certain requirements on the installers' physique. In other words, the current capsule installation is not very convenient and needs improvement. Summary of the Invention

[0005] To improve the ease of installation between the capsule and the tank, this application provides a horizontal foam liquid pressure storage tank and its assembly method.

[0006] The technical solution provided in this application for a horizontal foam liquid pressure storage tank and its assembly method is as follows:

[0007] A horizontal foam liquid pressure storage tank includes a horizontal tank body and a capsule disposed within the tank body. The tank body has a left mounting port and a right mounting port at its two ends along its length. The tank body has an outlet on its upper side and an inlet on its lower side. The capsule has flanges corresponding to the left mounting port, right mounting port, outlet, and inlet. The tank body has first flanges at the left mounting port, right mounting port, outlet, and inlet. Four flanges correspond one-to-one with four first flanges. Each flange extends beyond and covers a first flange. A second flange for fixing the flange is disposed on the first flange.

[0008] By adopting the above technical solution, during the assembly of this pressure storage tank, two ropes are first lowered vertically from the outlet and passed through the lower inlet. The upper end of one rope is fixed to the first flange at the outlet with a slip knot, and the lower end of the other rope is fixed to the first flange at the inlet with a slip knot. Then, a long rod with a hook is inserted from the right mounting port of the tank body, hooks the rope, and pulls the rope so that it exits from the right mounting port. Similarly, the long rod with a hook is extended from the right mounting port to the left mounting port to pull the other rope out of the right mounting port. Then, the three ropes are fixed to the corresponding flanges of the capsule with slip knots. Pulling the rope will pull the flange out from the corresponding first flange side. Then, the ropes are released, the flange is wrapped around the corresponding first flange, and the flange is fixed with the second flange. Finally, the flange at the right mounting port is fixed to complete the installation of the capsule. The horizontal foam liquid pressure storage tank of this application does not require the installation personnel to enter, and does not restrict the size of the installation personnel, thus providing greater convenience.

[0009] Preferably, the inner wall of the tank is provided with an annular water inlet pipe, the water inlet pipe surrounds the periphery of the capsule, the tank body has a water inlet that communicates with the water inlet pipe, and the water inlet pipe is provided with a plurality of water outlet holes spaced apart.

[0010] By adopting the above technical solution, the inlet is connected to the fire-fighting pipeline. During fire-fighting operations, fire-fighting water enters the inlet pipe from the inlet and exits from the outlet of the inlet pipe. The water pressure compresses the capsule, thereby causing the foam liquid to be discharged from the outlet. The inlet pipe is set in a ring shape, which makes the capsule bear force evenly, less prone to damage, and helps to improve the service life of the capsule.

[0011] Preferably, the tank body has an air outlet on one side of the liquid outlet, and the air outlet is connected to the inner cavity of the tank body.

[0012] By adopting the above technical solution, when the capsule is installed into the can, the capsule is not filled with foam liquid. When filling the capsule with foam liquid, the vent needs to be opened so that the air in the can is discharged as the capsule expands.

[0013] Preferably, the inner wall of the tank is provided with an annular drain pipe, the drain pipe surrounds the periphery of the capsule, the tank has a drain outlet connected to the drain pipe on the side of the liquid inlet, and the drain pipe has a plurality of drain holes spaced apart.

[0014] By adopting the above technical solution, when filling the capsule with foam liquid, the drain outlet is opened to drain the water in the tank, thereby allowing the capsule to expand. The drain pipe is designed in a ring shape to reduce the risk of scratching the capsule and help ensure the capsule's service life.

[0015] Preferably, the air outlet is connected to the drain pipe.

[0016] By adopting the above technical solution, during the initial filling of foam liquid, the gas inside the tank can enter the drain pipe through the drain hole and exit from the vent. In traditional tanks, the capsule is fixed with a cable tie, which poses a risk of blocking the vent. Therefore, a vent pipe is installed to extend into the tank. The vent pipe is usually set horizontally, parallel to the length of the capsule. When the capsule expands, there will still be sharp edges at the opening of the vent pipe. If the capsule comes into contact with the pipe, it may be worn or punctured, affecting the capsule's service life. In this application, the drain pipe is set in a ring shape, so there are no sharp edges in contact with the capsule, and the gas can be discharged directly from the drain pipe, thus ensuring the service life of the capsule.

[0017] Preferably, the capsule is provided with a porous tube, the two ends of which are respectively connected to the liquid outlet and the liquid inlet, and the tube wall of the porous tube is supported by the flange at the liquid outlet and the liquid inlet. The porous tube is provided with a plurality of through holes for the foam liquid to enter and exit.

[0018] By adopting the above technical solution, in actual use, when fire water enters the tank, if the fire water squeezes the flange at the outlet or the flange at the inlet, the flange may block the outlet and inlet. By using a porous tube inserted into the capsule to support the flange, it helps to prevent the outlet and inlet from being unable to drain under the pressure of the fire water.

[0019] An assembly method for a horizontal foam liquid pressure storage tank, comprising the following steps:

[0020] S1: Lower the two ropes vertically from the outlet and through the inlet on the lower side;

[0021] S2: The upper end of one rope is fixed to the first flange of the outlet with a slip knot, and the lower end of the other rope is fixed to the first flange of the inlet with a slip knot;

[0022] S3: Use a long rod with a hook-shaped end to extend into the tank through the right installation port, hook the rope, and pull the rope so that the rope extends out from the right installation port;

[0023] S4: Using a long, hook-shaped rod, insert it again into the tank from the right mounting port and extend it to the left mounting port. Hook another rope and pull the rope out from the right mounting port. Secure the end of the rope to the first flange on the left mounting port with a slip knot.

[0024] S5: The free ends of the three ropes are fixed to the corresponding flaps on the capsule. Then, the fixed ends of the three ropes and the can are dragged to put the capsule into the can and make the upper and lower sides and the left flap of the capsule move to the corresponding first flange and extend out of the first flange. At the same time, the right flap of the capsule covers the first flange at the right installation port.

[0025] S6: Release the ropes, use the four second flanges to fix the four first flanges, press the flanges tight to achieve fixation, and the installation is complete.

[0026] By adopting the above technical solution, the capsule's flanges are moved to their corresponding first flanges using rope traction. Then, the second flanges are used to press and fix the flanges, thus installing the capsules. During this process, the installers can work from the outside of the tank without entering it, which means there are no requirements on the installers' body shape. The assembly of the capsules and the tank is more convenient and unrestricted.

[0027] Preferably, in step S6, the second flange is first fixed to the first flange at the inlet, left mounting port and right mounting port, and then the porous tube is vertically hoisted into the capsule from the upper outlet. The lower end of the porous tube overlaps the second flange, and the upper end of the porous tube is located inside the outlet. Finally, the second flange is fixed to the first flange at the outlet.

[0028] By adopting the above technical solution, the porous tube is hoisted into the capsule, which supports the flanges at the inlet and outlet. This helps to prevent the fire water from entering the tank and compressing the capsule, causing the flanges to be squeezed together and affecting the entry and exit of the foam liquid.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. The tank body is equipped with installation ports on all four sides, and the capsule is equipped with four flanges. The four flanges of the capsule are moved to the corresponding installation holes by rope traction, and the flanges are fixed by the first flange and the second flange, thereby realizing the installation of the capsule. During this installation process, the installer does not need to enter the tank body, that is, there are no requirements for the installer's body shape, which improves the convenience of capsule and tank body installation and reduces restrictions.

[0031] 2. Both the water inlet pipe and the drain pipe are arranged in a ring around the periphery of the capsule, which reduces the risk of scratching when in contact with the capsule and helps to ensure the lifespan of the capsule;

[0032] 3. The capsule installation does not require lifting rings or cable ties, so there will be no situation where cable ties block the air outlet. That is, there is no need to connect the air outlet to the air outlet pipe. Traditional air outlet pipes must extend into the tank body, and the outlet of the air outlet pipe will scrape against the capsule. Therefore, the capsule in the pressure tank of this application has a longer service life. Attached Figure Description

[0037] The present application will be further described in detail below with reference to Figures 1-3.

[0038] This application discloses a horizontal foam liquid pressure storage tank and its assembly method.

[0039] Referring to Figures 1 and 2, the horizontal foam liquid pressure storage tank includes a horizontal tank body 1 and a capsule 2 disposed inside the tank body 1. The two ends (left and right ends) of the tank body 1 along its length are respectively formed with a left mounting port 11 and a right mounting port 12. A liquid outlet 13 is opened on the upper side of the tank body 1, and a liquid inlet 14 is opened on the lower side of the tank body 1. The capsule 2 is made of rubber, and the shape of the capsule 2 when inflated is adapted to the shape of the tank body 1. The capsule 2 is integrally formed with flanges 21 at the positions corresponding to the left mounting port 11, right mounting port 12, liquid outlet 13 and liquid inlet 14. The flanges 21 are in the shape of a circular flange. The tank body 1 is integrally formed with a first flange 3 at the left mounting port 11, right mounting port 12, liquid outlet 13 and liquid inlet 14. The four flanges 21 correspond one-to-one with the four first flanges 3. The flanges 21 extend out of the first flanges 3 and cover the first flanges 3. A second flange 4 is provided on the first flange 3 for pressing and fixing the flanges 21.

[0040] During assembly of the tank body 1 and capsule 2, the fixed bracket on the lower side of the tank body 1 supports the tank body 1. The capsule 2 is placed at the right mounting port 12 of the tank body 1. Then, two ropes are lowered vertically from the liquid outlet 13 and passed through the lower liquid outlet 13. The upper end of one rope is fixed to the first flange 3 at the liquid outlet 13 with a slip knot, and the lower end of the other rope is fixed to the first flange 3 at the liquid inlet 14 with a slip knot. Then, a long rod with a hook-shaped end is inserted into the right mounting port 12, hooks the two ropes, and pulls the ropes towards the right mounting port 12 so that the free ends of the two ropes protrude from the right mounting port 12. Subsequently, another rope is used to connect to the first flange 3 at the left mounting port 11. The flange 3 is secured with a slipknot. A long rod is then extended from the right mounting port 12 to the left mounting port 11 and hooked to the rope. The rope is then pulled to extend from the right mounting port 12. At this point, the free ends of the three ropes are all located at the right mounting port 12, and the three free ends are respectively connected to the three flanges 21 corresponding to the capsule 2. The capsule 2 is then inserted into the tank 1, and the flanges 21 are pulled by the ropes, causing them to extend from the corresponding first flange 3. Finally, the ropes are released and secured by the second flange 4, thus assembling the capsule 2 and the tank 1. This process does not require the installer to enter the tank and has no requirements on the installer's physical condition, thereby improving the ease of installation and reducing limitations.

[0041] A water inlet 5 is provided on the upper side of the tank body 1. A ring-shaped water inlet pipe 6 is welded to the inner wall of the tank body 1. The water inlet pipe 6 surrounds the periphery of the capsule 2. The water inlet 5 is connected to the water inlet pipe 6. Several water outlet holes 61 are provided on the water inlet pipe 6 at intervals.

[0042] In practice, the inlet 5 and outlet 13 on tank 1 are uniformly connected to the fire-fighting pipeline. During fire-fighting operations, fire-fighting water enters the inlet pipe 6 from the inlet 5, and then uniformly enters the tank 1 from the outlet 61, compressing the capsule 2. This causes the foam liquid to enter the fire-fighting pipeline from the outlet 13, forming a certain proportion of foam mixture. Setting the inlet pipe 6 in a ring shape ensures that the capsule 2 is subjected to uniform force, is less prone to damage, and thus improves the service life of the capsule 2.

[0043] A ring-shaped drain pipe 7 is welded to the inner wall of the tank body 1. The drain pipe 7 surrounds the periphery of the capsule 2. Several drain holes 71 are spaced apart on the drain pipe 7. An air outlet 8 is opened on the upper side of the tank body 1 and is connected to the drain pipe 7. A drain outlet 9 is opened on the lower side of the tank body 1 and is connected to the drain pipe 7.

[0044] After capsule 2 is installed, open inlet 14 and outlet 8. During foam filling, capsule 2 expands, and air inside tank 1 is expelled through outlet 8. In subsequent use, the space between tank 1 and capsule 2 will be filled with fire-fighting water. When filling with foam solution again, open drain 9 to drain the fire-fighting water from tank 1 as capsule 2 expands. Drain pipe 7 is designed as a loop for rapid drainage of fire-fighting water.

[0045] In traditional pressure tanks, capsule 2 is installed and fixed by connecting it with cable ties and lifting rings. The lifting rings are located on the upper side of the tank body 1. Since the vent 8 is located on the upper side of the tank body 1, in actual operation, in order to avoid the cable ties blocking the vent 8, an exhaust pipe is connected to the vent 8. The exhaust pipe is located inside the tank body 1, and the opening of the exhaust pipe is in contact with capsule 2, which can cause scratching and eventually damage capsule 2. In this application, the cable tie connection method is eliminated, and the exhaust pipe is not required, thus ensuring the service life of capsule 2.

[0046] In addition, a vertical porous tube 10 is provided inside the capsule 2. The wall of the porous tube 10 has several through holes 101 for the foam liquid to enter and exit. The upper and lower ends of the porous tube 10 are located inside the inlet 14 and outlet 13, respectively, and are limited by the walls of the outlet 13 and inlet 14. Both the upper and lower ends of the porous tube 10 are open. The closure of the porous tube 10 supports the flanges 21 at the inlet 14 and outlet 13. In practice, after the capsule 2 is installed, the porous tube 10 is vertically hoisted into the capsule 2 from the outlet 13. At this time, the lower end of the porous tube 10 will abut against the second flange 4 at the inlet 14, and the upper end of the porous tube 10 will be located inside the outlet 13. The outlet 13 and inlet 14 limit the end of the porous tube 10 in the horizontal direction.

[0047] When fire water enters the tank 1, the fire water squeezes the upper and lower flanges 21, causing the flanges 21 to converge towards the center, which prevents the foam liquid from being discharged from the outlet 13 or filled from the inlet 14. Using the perforated pipe 10 to support the flanges 21 can effectively avoid this situation.

[0048] The implementation principle of a horizontal foam liquid pressure storage tank in this application embodiment is as follows: the four flanges 21 of the capsule 2 are assembled with the tank body 1 through the action of the first flange 3 and the second flange 4. The assembly process can be achieved by simply using rope traction, without requiring the installation personnel to enter the tank body 1. There are no requirements on the size of the installation personnel, making it more convenient and less restrictive.

[0049] Referring to Figure 3, an assembly method for a horizontal foam liquid pressure storage tank includes the following steps:

[0050] S1: Lower the two ropes vertically from the outlet 13 and pass them through the inlet 14 on the lower side;

[0051] S2: The upper end of one rope is fixed to the first flange 3 of the outlet 13 by a knot, and the lower end of the other rope is fixed to the first flange 3 of the inlet 14 by a knot.

[0052] S3: Using a long rod with a hook-shaped end, extend it into the tank 1 through the right mounting port 12, hook the rope, and pull the rope so that the rope extends out from the right mounting port 12;

[0053] S4: Using a long, hook-shaped rod, extend it again into the tank 1 from the right mounting port 12 and to the left mounting port 11, hook another rope, pull the rope out from the right mounting port 12, and fix the end of the rope to the first flange 3 on the left mounting port 11 with a slip knot.

[0054] S5: The free ends of the three ropes are fixed to the corresponding flanges 21 on the capsule 2 with a slip knot. Then, the fixed ends of the three ropes and the can 1 are dragged to put the capsule 2 into the can 1, and the upper and lower sides and the left flanges 21 of the capsule 2 are moved to the corresponding first flanges 3 and extended out of the first flanges 3. At the same time, the right flanges 21 of the capsule 2 cover the first flanges 3 at the right installation port 12.

[0055] S6: Release the ropes, first use the second flange 4 to fix the first flange 3 at the inlet 14, left mounting port 11 and right mounting port 12, then vertically hoist the porous tube 10 into the capsule 2 from the upper outlet 13. The lower end of the porous tube 10 overlaps the second flange 4, and the upper end of the porous tube 10 is located inside the outlet 13. Finally, use the second flange 4 to fix the first flange 3 at the outlet 13. The installation is complete.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
