Description

Technical Field

[0001] This invention belongs to the field of water distributors, and specifically relates to a water distributor for small skid-mounted equipment. Background Technology

[0002] Small skid-mounted equipment is a prefabricated, modular system typically assembled and tested in a manufacturing plant before being transported to the site for installation, either as a whole or in sections. Small skid-mounted equipment includes components such as equipment, piping, valves, instruments, and control systems, which can be configured and adjusted to adapt to different operational needs and conditions. With its advantages of high efficiency, reliability, and flexibility, small skid-mounted equipment is widely used in various industries, including chemical, petroleum, natural gas, power, and environmental protection.

[0003] Water distributors in small skid-mounted systems are used to distribute water from one input source to multiple output channels. They typically include valves, piping, and control systems to ensure accurate and efficient water distribution. The design and operation of water distributors usually require consideration of many factors, such as water demand, water quality, water pressure, water temperature, and environmental conditions, all of which can affect the performance and efficiency of the water distributor.

[0004] Most existing water distributors use a perforated structure, which can only distribute water from the main water pipe to the branch pipes. They neglect the flow control of water in each branch pipe during the distribution process. The flow control is not accurate for small flow rates and small areas, which cannot meet the requirements for application in small skid-mounted equipment. When there is a quantitative requirement for the water flow in the branch pipes, a flow regulator needs to be installed on each branch pipe to achieve the flow control effect. This not only increases the cost of the device, but also makes the device structure complex and difficult to operate. Summary of the Invention

[0005] The first technical problem this invention aims to solve is that existing water distributors neglect the flow control of water in each branch pipe during the water distribution process. This results in inaccurate flow control for small flow rates within a limited area, failing to meet the requirements for applications on small skid-mounted equipment. The second technical problem this invention aims to solve is that when there are quantitative requirements for the water flow in the branches, flow regulators need to be installed on each branch of the existing water distributor to achieve the flow control effect. This not only increases the cost of the device but also makes the device structure complex and difficult to operate. Therefore, this invention provides a water distributor for small skid-mounted equipment.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] This invention provides a water distributor for a small skid-mounted device, comprising: an inlet pipe, a distributor housing, distributor branch assemblies, an outlet buffer pipe, and a plug. The inlet of the distributor housing is connected to the inlet pipe, and the outlet of the distributor housing is connected to the outlet buffer pipe. A plug is installed (e.g., by thread) at the end of the outlet buffer pipe. A central through hole is axially oriented through the center of the distributor housing, with one end serving as the inlet and the other as the outlet. A plurality of spaced and parallel distributor branch mounting holes are oriented perpendicularly to the central through hole on one or both sides. Distributor branch assemblies are installed within these mounting holes, with one end connected to the central through hole and the other end connected to a branch water pipe. The system includes: a ferrule fitting embedded in the branch mounting hole of a distributor, comprising an inner end embedded in the branch mounting hole and an outer end protruding from the outside of the distributor housing. The ferrule fitting has a through hole penetrating its longitudinal axis. From the inner end to the outer end, the through hole includes a wide-diameter section, a narrow-diameter section, and an insertion groove for inserting a branch water pipe (generally, the inner diameter of the narrow-diameter section is equal to or slightly larger than the outer diameter of the branch water distribution pipe), and a reduced-diameter section located at the transition between the wide and narrow-diameter sections. A through-hole nut is connected to the outer end of the ferrule fitting, and the branch water pipe is fixed in the insertion groove by the through-hole nut. A branch water distribution pipe is inserted into the through hole of the ferrule fitting. The branch water distribution pipe is sequentially fitted with a first ferrule and a through-hole screw. The first ferrule is fixed to the reduced-diameter section of the through hole, clamping the branch water distribution pipe. The through-hole screw fixes the branch water distribution pipe in the through hole at the inner end of the ferrule fitting.

[0008] The through-hole type nut has a through hole through which the branch water pipe passes (the diameter of the through hole is basically equal to or slightly larger than the outer diameter of the branch water pipe), and the outer end of the compression fitting is connected to the branch water pipe through the through-hole type nut.

[0009] Furthermore, the diameter of the insertion groove is consistent with the outer diameter of the branch water pipe.

[0010] Furthermore, in the water distributor for small skid-mounted equipment described above, the inner diameter of the branch water distribution pipe is 1-10 mm and the length is 2.5-10 cm. One end of the branch water distribution pipe is flush with or slightly protrudes from the side wall of the central through hole (e.g., protruding 0.5-1 cm). The other end of the branch water distribution pipe extends into the insertion groove of the compression fitting, at least flush with the bottom of the insertion groove, or beyond the bottom of the insertion groove by a distance, e.g., 0.5-3 cm, thereby entering the installed branch water pipe.

[0011] Furthermore, in the water distribution device for small skid-mounted equipment described above, the branch water distribution pipes are made of copper, steel, cast iron, stainless steel, or plastic, and the plastic pipes are made of polyethylene (PE), polyvinyl chloride (PVC), or polypropylene random copolymer (PPR).

[0012] Furthermore, in the water distributor for small skid-mounted equipment described above, the side of the insertion groove near the outer end of the ferrule connector expands outward, i.e., it has an outwardly expanding sloping structure, which is used to insert a second ferrule between the insertion groove and the branch water pipe. The second ferrule is used to clamp and fix the branch water pipe in the insertion groove of the ferrule connector; preferably, the second ferrule is a double ferrule.

[0013] Furthermore, in the water distributor for small skid-mounted equipment described above, the first ferrule is a single ferrule.

[0014] Furthermore, in the water distributor for small skid-mounted equipment described above, the distributor branch assembly also includes an annular gasket. The gasket is disposed in the gap between the outer wall of the distributor housing and the ferrule connector, and is used to seal the connection between the ferrule connector and the distributor branch mounting hole.

[0015] Furthermore, in the water distributor for small skid-mounted equipment described above, the distributor branch mounting hole is a stepped hole with an outer diameter (near the outer wall of the water distributor) larger than the inner diameter (near the inner wall of the water distributor). The inner end of the ferrule can contact or be close to the bottom of the outer hole with a larger diameter, for quickly fastening the distributor branch assembly to the distributor housing.

[0016] Furthermore, in the water distributor for small skid-mounted equipment described above, the ferrule connector has a cross-shaped longitudinal section, and the size of the portion embedded in the distributor branch mounting hole is consistent with the size of the distributor branch mounting hole.

[0017] Furthermore, in the water distributors used in the aforementioned small skid-mounted equipment, the distance between the inner end of the ferrule connector and the central through hole is at most 1 / 2 to 1 / 3 of the distributor housing wall thickness.

[0018] Furthermore, the ports connecting the distributor housing to the inlet pipe, distributor branch assembly, and outlet buffer pipe are all equipped with internal threads for quick installation. The inlet pipe is threaded to the distributor housing, the distributor branch assembly is threaded to the distributor housing, the outlet buffer pipe is threaded to the distributor housing, and the plug is threaded to the outlet buffer pipe.

[0019] Furthermore, the through-hole screw is threaded to the ferrule connector, the branch water distribution pipe is fixedly connected to the ferrule connector via a single ferrule, the ferrule connector is threaded to the distributor housing, and the through-hole nut is threaded to the ferrule connector. The branch water pipe is fixedly connected via a second ferrule at the top of the distributor branch assembly.

[0020] Furthermore, in a multi-channel system, flow distribution is achieved by adjusting the resistance drop of each channel. For example, the pressure difference ΔPf can be calculated using the following formula, and uniform flow distribution can be achieved by adjusting the length and inner diameter of the branch flow distribution pipe:

[0021] To evenly distribute the water flow in the main pipeline to the branch pipelines, the pressure difference ΔPf (in Pa) caused by the resistance of the water along each branch path must be the same, that is:

[0022] ΔPf1=ΔPf2=…=ΔPfn

[0023] The energy loss of each tributary can be decomposed into the pressure difference ΔPf in the main pipeline. 主管道 Pressure difference ΔPf between branch water flow distribution pipes 分配管 ,Right now:

[0024] ΔPf=ΔPf 主管道 +ΔPf 分配管

[0025] The pressure difference in a straight pipe can be calculated using the following formula:

[0026] ΔPf=ρh f

[0027]

[0028] Where ρ represents the material density, with units of kg / m³. 3 A water temperature of 30℃ can be taken as 995.7; h f This represents energy loss, expressed as kinetic energy u. 2 / 2 is a function, with units of J / kg; λ is a dimensionless coefficient, generally ranging from 0.01 to 0.1, which is the friction coefficient, a function of the Reynolds number or the Reynolds number and the pipe wall roughness. The value here needs to be determined according to the pipe material to determine the corresponding friction stress. The flow state inside the pipe is determined by the law followed by the friction stress, so this value also varies with the flow pattern (for determining the value of λ, please refer to "Chemical Engineering Principles (4th Edition)" published by Higher Education Press, authors: Chai Chengjing and Jia Shaoyi, School of Chemical Engineering, Tianjin University, published on December 1, 2022); l represents the straight pipe length, with units of mm. In this calculation scenario, the length of the main pipe can be represented by L, and the length of the distribution pipe can be represented by ln; d represents the straight pipe inner diameter, with units of mm. In this calculation scenario, the inner diameter of the main pipe can be represented by D, and the inner diameter of the distribution pipe can be represented by dn; u represents the flow velocity, with units of m / s.

[0029] The flow velocity u can be calculated using the following formula:

[0030]

[0031] Where Fg represents mass flow rate in kg / h; d represents pipe diameter in mm. In this calculation scenario, the main pipe diameter can be represented by D and the distribution pipe diameter by dn.

[0032] In summary, the pressure difference at point 1 of the branch pipe is:

[0033]

[0034] The pressure difference at point 2 of the branch pipe is

[0035]

[0036] The pressure difference at point 3 of the branch pipeline is

[0037]

[0038] …

[0039] The pressure difference at point n on the branch pipe is

[0040]

[0041] Where D represents the lateral distance from the water inlet to a branch pipe in the water distributor, in mm; Δx is the distance between each branch pipe, in mm.

[0042] By adjusting the inner diameter d and length ln of the branch water flow distribution pipe, the pressure difference ΔPfn at all branch pipes is adjusted, thereby achieving uniform flow distribution.

[0043] Furthermore, in the aforementioned water distributor for small skid-mounted equipment, the through-hole nut is made of copper, steel, cast iron, stainless steel, or plastic, wherein the plastic is polyethylene (PE), polyvinyl chloride (PVC), or a random copolymer of polypropylene (PPR); and / or,

[0044] The second ferrule is made of copper, steel, cast iron, stainless steel, or plastic, wherein the plastic is polyethylene (PE), polyvinyl chloride (PVC), or a random copolymer of polypropylene (PPR); and / or,

[0045] Compression fittings are made of copper, steel, cast iron, stainless steel, or plastic, wherein the plastic is polyethylene (PE), polyvinyl chloride (PVC), or a random copolymer of polypropylene (PPR); and / or,

[0046] The gasket is made of copper, steel, cast iron, stainless steel, or plastic, wherein the plastic is polyethylene (PE), polyvinyl chloride (PVC), or a random copolymer of polypropylene (PPR); and / or,

[0047] The first ferrule is made of copper, steel, cast iron, stainless steel, or plastic, wherein the plastic is polyethylene (PE), polyvinyl chloride (PVC), or a random copolymer of polypropylene (PPR); and / or,

[0048] Through-hole screws are made of copper, steel, cast iron, stainless steel or plastic, wherein the plastic is polyethylene (PE), polyvinyl chloride (PVC) or polypropylene random copolymer (PPR).

[0049] The principle behind this invention's water distributor for small skid-mounted equipment, which provides precise flow control within a small flow range, is as follows: Resistance drop is related to the length of the channel through which the fluid passes. With the same diameter and surface roughness, a longer pipe means the fluid needs to travel a longer distance, thus resulting in a greater resistance drop. Compared to conventional orifice-structure water distributors, with the same orifice diameter, branch water distribution pipe inner diameter, and surface roughness, the orifice is much shorter than the pipe, resulting in a shorter distance for the fluid to pass through it. Therefore, the resistance drop through the orifice is typically less than that through the pipe. Furthermore, when fluid flows in a pipe, a layer with significant velocity variations typically forms near the pipe wall; this is the boundary layer, which increases the fluid's resistance drop. For orifice-structure water distributors, due to the shorter orifice length, the boundary layer is not fully formed, resulting in a smaller resistance drop. In short, this invention increases the resistance drop, reduces the fluid velocity, and decreases noise and vibration caused by excessive velocity, thereby effectively controlling the fluid flow rate and keeping it within the required flow range.

[0050] The installation method of the water distributor for small skid-mounted equipment according to the present invention is as follows: First, insert and clamp the first ferrule (single ferrule) into the appropriate position of the branch water distribution pipe. Then, insert the branch water distribution pipe with the first ferrule inserted into the lower through-hole of the ferrule connector, ensuring the first ferrule fits tightly against the reduced diameter section of the through-hole. Next, screw in a through-hole screw to fix it to the lower end of the ferrule connector. Then, place a gasket in the threaded hole on the distributor housing for installing the distributor branch components. Finally, insert the ferrule connector, equipped with the first ferrule, through-hole screw, and branch water distribution pipe, into the distributor housing from above the distributor housing and the gasket. Finally, place the second ferrule into the pre-drilled hole at the upper part of the ferrule connector. Finally, assemble a through-hole nut on top of the ferrule connector and the second ferrule, and tighten the threads of the through-hole nut for fixation. This completes the installation.

[0051] The present invention has the following beneficial effects:

[0052] (1) The water distributor for small skid-mounted equipment of the present invention uses a distributor branch assembly including branch water flow distribution pipes for water distribution treatment. In the range of small flow (e.g., 5-50 kg / h), the water flow of each branch is controlled more accurately, and the difference in water flow of each branch can be controlled within 1-2%. This solves the problem that the existing water distributors are not accurate in controlling the flow in a small range of small flow and cannot meet the requirements for application in small skid-mounted equipment.

[0053] (2) The water distributor for small skid-mounted equipment of the present invention is detachable and easy to install. It can be disassembled and installed into branch water flow distribution pipes of different lengths and inner diameters according to the usage requirements. It can accurately adjust and control the flow rate of each branch water pipe to achieve the purpose of evenly distributing the water in the main water pipe. The device can accurately control the flow rate of each branch without the use of a flow regulator, which reduces the cost of the device and makes the device simple and easy to operate. It solves the problem that when there is a quantitative requirement for the water flow rate on the branch, it is necessary to install a flow regulator on each branch to achieve the flow control effect, which not only increases the cost of the device, but also makes the device complex and difficult to operate.

[0054] (3) The water distributor for small skid-mounted equipment of the present invention can shorten the outlet buffer pipe by 5-10cm by increasing the disturbance in the fluid in a small range through the branch water flow distribution pipe, saving about 50-200 yuan in costs. The reason for shortening the outlet buffer pipe is as follows: Compared with the conventional hole structure water distributor, when the diameter of the small hole and the inner diameter of the branch water flow distribution pipe are the same and the surface roughness is the same, the length of the pipe will be much longer than the hole. The contact between the fluid and the pipe wall increases the disturbance, and the disturbance increases the turbulence of the fluid. This makes the resistance drop of the turbulent fluid usually greater than that of the laminar fluid, thereby increasing the resistance drop of the fluid. The increase in resistance drop will achieve a certain buffering effect, thereby shortening the length of the outlet buffer pipe.

[0055] (4) The water distributor for small skid-mounted equipment of the present invention has a simple structure, is easy to install and has low maintenance cost; it occupies a small area, which is conducive to the movement and transportation of equipment; it has high reliability and stability and low failure frequency;

[0056] (5) The water distributor for small skid-mounted equipment of the present invention can prevent blockage and extend the time for cleaning blocked pipes by 15 to 20 days. The reason for preventing blockage is as follows: the flow path of fluid in the small pipe is longer than that in the small hole. In addition, the inside of the small pipe is a continuous channel. The fluid flows more smoothly in the small pipe than in the small hole, and it is not easy to form vortices or dead corners. Vortices or dead corners are places where particles or substances are easy to block. Therefore, the water distributor reduces the possibility of blockage. Attached Figure Description

A through-hole type nut is connected to the outer end of the compression fitting. 31. The branch water pipe is fixed in the insertion groove by the through-hole nut 31 (the branch water pipe generally abuts the bottom of the insertion groove). The branch water flow distribution pipe 37 is inserted into the through hole of the ferrule connector. The branch water flow distribution pipe 37 is fitted with a first ferrule 35 and a through-hole screw 36 in sequence. The first ferrule 35 is fixed to the reduced diameter section of the through hole, clamping the branch water flow distribution pipe 37. The through-hole screw 36 fixes the branch water flow distribution pipe 37 in the through hole at the inner end of the ferrule connector 33.

[0066] The through-hole type nut 31 has a through hole through which the branch water pipe passes, and the outer end of the compression fitting 33 is connected to the branch water pipe through the through-hole type nut 31.

[0067] In a preferred embodiment, the inner diameter of the branch water flow distribution pipe 37 is 1-10 mm, the wall thickness is 1-2 mm, and the length is 2.5-10 cm. One end of the branch water flow distribution pipe 37 is flush with the side wall of the central through hole 21, and the other end of the branch water flow distribution pipe 37 extends into the insertion groove of the compression fitting 33, at least flush with the bottom of the insertion groove, or beyond the bottom of the insertion groove by a distance, for example, 0.5-3 cm, so as to enter the installed branch water pipe.

[0068] In another preferred embodiment, in the water distributor for small skid-mounted equipment described above, the branch water distribution pipe 37 is a copper pipe, steel pipe, cast iron pipe, stainless steel pipe or plastic pipe, wherein the plastic pipe is a polyethylene (PE) pipe, a polyvinyl chloride (PVC) pipe or a polypropylene random copolymer (PPR) pipe.

[0069] In another preferred embodiment, the side of the insertion groove near the outer end of the ferrule connector 33 expands outward, i.e., it has an outwardly expanding ramp-like structure, for inserting a second ferrule 32 between the insertion groove and the branch water pipe. The second ferrule 32 is used to clamp and fix the branch water pipe in the insertion groove of the ferrule connector 33; preferably, the second ferrule 32 is a double ferrule. The diameter of the hole axially penetrating at the center of the second ferrule 32 is equal to or slightly larger than the diameter of the branch water pipe.

[0070] Preferably, the first card sleeve 35 is a single card sleeve.

[0071] In another preferred embodiment, the distributor branch assembly 3 further includes an annular gasket 34 disposed in the gap between the outer wall of the distributor housing 2 and the ferrule connector 33 for sealing the connection between the ferrule connector 33 and the distributor branch mounting hole 22.

[0072] In another preferred embodiment, the distributor branch mounting hole 22 is a stepped hole with an outer diameter larger than the inner diameter, and the inner end of the ferrule connector 33 contacts or is close to the bottom of the outer hole with a larger diameter, for quickly fastening the distributor branch assembly 3 to the distributor housing 2.

[0073] In another preferred embodiment, the ferrule connector 33 has a cross-shaped structure, and the size of the portion embedded in the distributor branch mounting hole 22 is consistent with the size of the distributor branch mounting hole.

[0074] In this application, the through hole of the ferrule includes a wide diameter section and a narrow diameter section (the inner diameter of the narrow diameter section is equal to or slightly larger than the outer diameter of the branch water distribution pipe) from the inner end to the outer end, as well as a reduced diameter section located at the transition between the wide diameter section and the narrow diameter section. This structure, in which the tapered ferrule clamps the branch water distribution pipe and is embedded in the reduced diameter section, ensures that the branch water distribution pipe can be tightly inserted into the ferrule, thereby ensuring a good sealing effect. This structure can not only effectively prevent fluid leakage, but also improve the connection strength between the ferrule and the branch water distribution pipe.

[0075] In another preferred embodiment, the distance between the inner end of the ferrule connector 33 and the central through hole 21 is at most 1 / 2 to 1 / 3 of the wall thickness of the distributor housing 2.

[0076] The ports connecting the distributor housing 2 to the inlet pipe 1, the distributor branch assembly 3, and the outlet buffer pipe 4 are all equipped with internal threads for quick installation. The inlet pipe 1 is threaded to the distributor housing 2, the distributor branch assembly 3 is threaded to the distributor housing 2, the outlet buffer pipe 4 is threaded to the distributor housing 2, and the plug 5 is threaded to the outlet buffer pipe 4.

[0077] The through-hole screw 36 is threaded to the ferrule connector 33. The branch water flow distribution pipe 37 is fixedly connected to the ferrule connector 33 via a single ferrule 35. The ferrule connector 33 is threaded to the distributor housing 2. The through-hole nut 31 is threaded to the ferrule connector 33. The branch water pipe is fixedly connected via a second ferrule 32 at the top of the distributor branch assembly 3.

[0078] The inlet pipe 1 is tubular with a diameter of 1 to 5 cm. It can be made of copper, steel, cast iron, stainless steel, or plastic. The plastic pipe is made of polyethylene (PE), polyvinyl chloride (PVC), or polypropylene random copolymer (PPR).

[0079] The distributor housing 2 is a cuboid, with a length of 20-50cm, a width of 5-20cm, and a height of 5-10cm. It can be made of copper, steel, cast iron, stainless steel, polyethylene (PE), polyvinyl chloride (PVC), or polypropylene random copolymer (PPR).

[0080] The outlet buffer pipe is 4-shaped and has a diameter of 1-5cm. It can be made of copper, steel, cast iron, stainless steel, polyethylene (PE), polyvinyl chloride (PVC), or polypropylene random copolymer (PPR).

[0081] The plug 5 is a threaded cylinder with a round head. Its function is to prevent liquid from flowing out of the outlet buffer pipe. The plug 5 provides a seal and prevents leakage. The threaded design facilitates disassembly for flushing and maintenance of the water distributor. It has a diameter of 1–5 cm and can be made of copper, steel, cast iron, stainless steel, polyethylene (PE), polyvinyl chloride (PVC), or polypropylene random copolymer (PPR).

[0082] The central through hole 21 has the same length as the box body and a diameter of 1-5cm.

[0083] The depth of the distributor branch mounting hole 22 is 2-3cm, and the diameter is 1-3cm.

[0084] The distributor branch assembly 3 can be distributed on the four sides of the distributor housing 2, with 2 to 10 units arranged along each side of the distributor housing 2.

[0085] The through-hole nut 31 is cylindrical with a diameter of 1-5 cm. It has an axially extending hole in the center, the diameter of which is one-third to one-half the diameter of the nut. It can be made of copper, steel, cast iron, stainless steel, or plastic, specifically polyethylene (PE), polyvinyl chloride (PVC), or a random copolymer of polypropylene (PPR). The through-hole nut 31 is used to secure the second clamping sleeve 32, allowing it to tightly grip the branch water pipe.

[0086] The second ferrule 32 is preferably a double ferrule, formed by two single ferrules fitted together. Each single ferrule is conical, with an internal cylindrical hole for the branch water pipe to pass through. The diameter of the cylindrical hole is equal to or slightly larger than the diameter of the branch water pipe. The conical holes of the two single ferrules face each other, forming a space to clamp the branch water pipe. The ferrules can be made of copper, steel, cast iron, stainless steel, or plastic, specifically polyethylene (PE), polyvinyl chloride (PVC), or a random copolymer of polypropylene (PPR). In use, the second ferrule 32 is first placed into the hole at one end of the ferrule connector. Then, the branch water pipe is inserted into the cylindrical hole of the second ferrule 32. The through-hole nut 31 is then pressed on to secure it, and finally, the through-hole nut 31 is tightened to tightly clamp the branch water pipe. This structure effectively prevents the branch water pipe from slipping out under pressure or vibration, while also providing a good seal.

[0087] The compression fitting 33 has a cross-shaped longitudinal section, including two smaller diameter parts (preferably cylinders) at the top and bottom and a larger diameter part (preferably cylinder) in the middle. The smaller diameter part at the bottom is embedded in the distributor branch mounting hole 22 opened on the side wall of the distributor housing. The maximum diameter is 3-4 cm (the diameter of the larger diameter cylinder at the top is 2-3 cm, and the diameter of the smaller diameter cylinder at the bottom is 1-2 cm). It can be made of copper, steel, cast iron, stainless steel or plastic. The plastic is polyethylene (PE), polyvinyl chloride (PVC) or polypropylene random copolymer (PPR).

[0088] The gasket 34 is annular, with an inner diameter equivalent to the outer diameter of the lower part of the ferrule connector and an outer diameter equivalent to the diameter of a smaller cylinder below the ferrule connector 33. The thickness is 1-3mm, and it can be made of copper, steel, cast iron, stainless steel or plastic. The plastic is polyethylene (PE), polyvinyl chloride (PVC) or polypropylene random copolymer (PPR).

[0089] The first clamp 35 is a single clamp, which is conical in shape and has a cylindrical hole inside for the branch water flow distribution pipe 37 to pass through. It is used to insert the branch water flow distribution pipe 37 so that it can tightly clamp the branch water flow distribution pipe 37. The maximum diameter is 0.4 to 0.6 cm. It can be made of copper, steel, cast iron, stainless steel or plastic. The plastic is polyethylene (PE), polyvinyl chloride (PVC) or polypropylene random copolymer (PPR).

[0090] The through-hole type screw 36 includes a head for turning the screw and a threaded rod-shaped body. The body has a through hole in the middle for fixing the first ferrule 35 and the branch water flow distribution pipe 37. At the same time, due to the through hole in the center, it can be used to guide the branch water flow distribution pipe 37 that needs to be connected. The maximum diameter is 0.6 to 1 cm (head diameter is 0.6 to 1 cm, rod-shaped body diameter is 0.5 to 0.6 cm). An axial through hole is opened in the middle of the screw. The diameter of the hole is one-quarter to one-third of the diameter of the through-hole type screw. It can be made of copper, steel, cast iron, stainless steel or plastic. The plastic is polyethylene (PE), polyvinyl chloride (PVC) or polypropylene random copolymer (PPR).

[0091] The first ferrule 35 and the through-hole screw can not only fix the branch water flow distribution pipe 37 in the ferrule connector 33, but also precisely control the fixed position of the branch water flow distribution pipe 37 in the ferrule connector 33.

[0092] The installation method of the water distributor for small skid-mounted equipment in this embodiment is as follows: First, insert and clamp the first ferrule (single ferrule) 35 into the appropriate position of the branch water distribution pipe 37. Insert the branch water distribution pipe 37, with the first ferrule 35 inserted, into the lower through-hole of the ferrule connector 33, ensuring the first ferrule 35 is tightly against the reduced diameter section of the through-hole. Then, insert and tighten the through-hole screw 36 to fix it to the lower end of the ferrule connector 33. Finally, place the gasket 34 on the distributor housing 2 to install the distributor. At the threaded hole of the branch assembly 3, insert the ferrule connector 33, which is equipped with the first ferrule 35, the through-hole screw 36, and the branch water flow distribution pipe 37, into the water distributor housing 2 from above the gasket 34. Finally, place the second ferrule 32 into the reserved hole at the upper part of the ferrule connector 33. Finally, install the through-hole nut 31 on the ferrule connector 33 and the second ferrule 32, and tighten the thread of the through-hole nut 31 to fix it. This completes the installation.

[0093] Example 1

[0094] In this embodiment, the first ferrule 35 is a single ferrule, and the second ferrule 32 is a double ferrule. Two spaced and parallel distributor branch mounting holes 22 are formed on one side of the central through hole 21, perpendicular to the central through hole 21. A distributor branch assembly 3 is threaded into each distributor branch mounting hole 22. The distance between branch pipe 1 and branch pipe 2 is 30mm, the inner diameter of the main pipe is 13mm, and the friction coefficient λ of the main pipe is 1.570×10⁻⁶. -2 The friction coefficient λ1 of pipe 1 is taken as 1.007×10. -2 The friction coefficient λ2 of pipe 2 is taken as 1.197×10. -2By calculating the pressure difference ΔPf, the inner diameter of branch pipe 1 on one side is set to 4.91 mm and the length to 3.38 cm, and the inner diameter of branch pipe 2 on the other side is set to 4.33 mm and the length to 3.19 cm.
