Description

Technical Field

[0001] The present invention relates to the technical field of cooling and heating pipe installation, and in particular to a cooling and heating pipe installation device and an installation process. Background Art

[0002] The difference between the installation of cold and hot water pipes for air conditioners is that the temperature difference between the cold water temperature of the air conditioner and the ambient temperature is about 22-32℃, the cold contraction of the pipe is often small, and the requirements for cold insulation materials and thickness are based on the principle of preventing the pipe from generating condensation during use. The cold water pipe support and hanger need to prevent the generation of cold bridges. The temperature difference between hot water and ambient temperature is about 40-50℃, and the thermal expansion of the hot water pipe of the air conditioner is large. The insulation materials and thickness require that the temperature of the insulation shell meets the energy-saving and safety requirements, and there is no concern about the generation of condensation. Therefore, the focus of the support and hanger is the impact of thermal expansion on the building and others.

[0003] In the prior art, since the supporting points of the pipes are often at the bottom of the pipes and the convection transfer of heat is upward, the hot water pipes do not consider the transfer of thermal bridges. In the current installation process, the cold water pipe installation method is often used. The horizontal cross pipe can still solve the thermal expansion and contraction by the swinging method of the hanger, and the vertical pipe is generally only fixed to the wall by a clamp and an insulated pipe support. After a period of use, the vertical pipe will be displaced due to expansion and contraction. If it moves in the insulated pipe support, cracks will easily occur in the vertical pipe insulation layer on the inside of the insulated pipe support, and if the insulated pipe support is tight to the pipe, the bracket will be easily damaged.

[0004] Therefore, the prior art needs to be improved. Summary of the invention

[0039] Example 1

[0040] Please refer to Figures 1 to 7 , shown is a cooling and heating pipe installation device according to an embodiment of the present invention, and the specific structure and principle are described as follows.

[0041] Combination Figure 1 As shown, the existing heating and cooling pipes are generally composed of horizontal transverse pipes and vertical risers. In order to achieve fixed installation of the transverse pipes and the risers, the heating and cooling pipe installation device of the present invention mainly includes two parts: a telescopic hanger 1 and a sliding bracket 2, wherein the telescopic hanger 1 is used to connect the transverse pipe, and the sliding bracket 2 is used to connect the risers.

[0042] In some implementations of this embodiment, Figure 1 As shown, the telescopic hanger 1 of this embodiment 1 mainly includes three parts: a fixing member 101, a screw rod 102 and a hanger rod 103, wherein the fixing member 101 is made of channel steel, and the open side of the channel steel faces the vertical wall during installation, and the fixing member 101 is fixedly connected to the floor (roof) by expansion screws.

[0043] Further, combined with Figure 1 and Figure 3 As shown, a through hole 1011 is provided on the bottom plate of the fixing member 101, and a curved groove 1012 is provided on the top surface of the bottom plate of the fixing member 101, and the curved groove 1012 is connected with the through hole 1011. The top end of the screw rod 102 passes through the through hole 1011 and the curved groove 1012 in sequence, and a nut 1021 is threadedly connected on the screw rod 102, and the bottom of the nut 1021 has a curved head 1022, which is in a hemispherical shape, and the surface of the curved head 1022 fits the surface of the curved groove 1012, so that the curved head 1022 can slide along the curved groove 1012, thereby facilitating the deflection of the screw rod 102.

[0044] It should be noted that after the nut 1021 is rotated, it can move up and down along the screw rod 102, which is convenient for adjusting the suspension height of the cross pipe and has a better use effect.

[0045] Furthermore, combined Figure 1 and Figure 4 As shown, the screw rod 102 and the suspension rod 103 are connected by an elastic member 3. The elastic member 3 mainly includes a connecting member 301 and a first spring 302. The connecting member 301 can be made of square steel, and an opening is provided at the bottom of the connecting member 301 for the top end of the suspension rod 103 to pass through. A through hole 2 is provided at the top of the connecting member 301, and the bottom end of the screw rod 102 passes through the through hole 2, and then the top of the connecting member 301 is clamped by two nuts 1023 on the screw rod 102, which plays a fixing role.

[0046] It should be noted that a gasket is installed between the nut 1023 and the top of the connecting piece 301 to achieve a better fixing effect.

[0047] In some implementations of this embodiment, Figure 1 and Figure 4 As shown, the first spring 302 is vertically installed inside the connecting member 301, and a pad 303 is installed on the top of the first spring 302. The pad 303 has a round hole for the suspension rod 103 to pass through. The bottom of the first spring 302 is also installed with a pad 303. The size of the pad 303 is larger than the bottom opening of the connecting member 301, and it also has a round hole for the suspension rod 103 to pass through. The suspension rod 103 is a threaded rod. After the top of the suspension rod 103 vertically passes through the two pads 303, a nut 3 1031 is installed on the top of the suspension rod 103. The nut 3 1031 cannot pass through the pad 303 on the top, thereby limiting the suspension rod 103. The first spring 302 has deformation ability, thereby adapting to the expansion and contraction deformation caused by the horizontal pipe and the vertical pipe.

[0048] Further, the collar 104 is fixed at the bottom end of the suspension rod 103, and the collar 104 is sleeved on the outside of the transverse tube, and the collar 104 is a clamp. A heat insulating ring is arranged inside the collar 104, and the heat insulating ring is in direct contact with the transverse tube. The heat insulating ring is a rubber ring made of rubber material, which has good heat insulating performance, avoids affecting the collar 104, and has elasticity to adapt to the expansion and contraction deformation of the transverse tube.

[0049] In some implementations of this embodiment, Figure 1 and Figure 2 As shown, the sliding bracket 2 mainly includes three parts: a bracket body 201, a second ring sleeve 202 and an annular pipe support 203. The bracket body 201 can be made of channel steel. When installed, the opening side of the channel steel faces the roof. The bracket body 201 is fixedly connected to the vertical wall through expansion screws. An opening is opened on the side of the bracket body 201 away from the vertical wall. The second ring sleeve 202 is installed at the opening position, and the vertical pipe is installed inside the second ring sleeve 202.

[0050] Further, combined with Figure 2 and Figure 5 As shown, the ring sleeve 202 adopts a clamp, and the two halves of the clamp are respectively clamped to the outer plate of the bracket body 201 by bolts, and the riser is fixed. A hemispherical groove is provided inside the ring sleeve 202, and a ball 6 coated with lubricating grease is installed in the groove. The ball 6 adopts a steel ball. The annular pipe support 203 is sleeved on the outside of the riser and fixedly connected to the riser. A slider 5 is installed on the outer surface of the annular pipe support 203. Six sliders 5 are evenly arranged around the center of the annular pipe support 203, and the corresponding balls 6 are also evenly arranged around. The six sliders 5 and the six balls 6 are aligned one by one. When the riser moves in the vertical direction due to expansion or contraction, the annular pipe support 203 also moves, and the balls 6 roll on the surface of the slider 5 to avoid damaging the sliding bracket 2.

[0051] It should be noted that the annular pipe support 203 is a rubber ring, which has the function of heat insulation and can be deformed to adapt to the expansion and contraction deformation of the vertical pipe.

[0052] In some implementations of this embodiment, Figure 6 As shown, a second spring 8 is provided to support the vertical expansion and contraction of the riser. Figure 6 As shown, the retaining ring 204 is annular, and the retaining ring 204 is fixedly connected to the inner wall of the ring sleeve 202, and the two retaining rings 204 are respectively located on the upper side and the lower side of the ball 6. The retaining rod 7 is a metal rod, and one end of the retaining rod 7 is fixedly connected to the outer wall of the vertical tube, and the other end of the retaining rod 7 passes through the annular tube support 203. The second spring 8 is sleeved on the outside of the annular tube support 203, and the ends of the second spring 8 are respectively in contact with the retaining rod 7 and the retaining ring 204. When the vertical tube moves downward, the upper second spring 8 is compressed, and when the vertical tube moves upward, the lower second spring 8 is compressed.

[0053] Further, combined with Figure 6 and Figure 7 As shown, in order to make the ball 6 roll better, a rotating shaft 601 is fixedly connected on both sides of the ball 6, and a clamping groove is provided inside the ring sleeve 202. The clamping groove is located on both sides of the groove for installing the ball 6, and the rotating shaft 601 is embedded in the clamping groove. A strip-shaped anti-skid pattern 1 602 is provided on the surface of the ball 6, and the curve of any anti-skid pattern 1 602 is in the same plane as the rotating shaft 601. A rolling groove 501 is provided on the surface of the slider 5, and an anti-skid pattern 2 502 is provided on the surface of the rolling groove 501. The anti-skid pattern 2 502 and the anti-skid pattern 1 602 abut against each other to increase friction, so that the rolling effect of the ball 6 is better.

[0054] Example 2

[0055] This embodiment provides a cooling and heating pipe installation process, using the cooling and heating pipe installation device of Example 1, and also includes the following method.

[0056] According to the designed 3D building drawing, the designed pipelines, including the heating and cooling pipe installation device of Example 1, are reflected on the drawing, and the telescopic hanger 1 and the sliding bracket 2 are numbered, and the unreasonable parts are adjusted to ensure that the pipes are free of collision, easy to operate, easy to repair or replace wearing parts, and the channels and spaces meet the user requirements, ensuring that there is no adverse effect on fire protection facilities and lighting, and that the building structure should not be affected after the upgrade space of various systems is reserved. After the design is completed, it will be confirmed by the design department before implementation.

[0057] According to the 3D architectural drawing, reserved casings and embedded parts are arranged in the civil engineering process. When the civil engineering conditions are ripe, the lines are laid out and holes are drilled to install expansion bolts before the roof is plastered, ensuring that the drilling will reduce the pollution to the civil engineering during the subsequent installation process.

[0058] Make or purchase the heating and cooling pipe installation device, horizontal pipe, and vertical pipe according to the 3D architectural drawing. If the telescopic hanger 1 and the sliding bracket 2 are made by the production method, sufficient time must be left to ensure that the paint of the heating and cooling pipe installation device is fully dried before installation. The finished product of the heating and cooling pipe installation device must be properly wrapped to prevent contamination during placement, and the surface of the heating and cooling pipe installation device must be numbered for easy installation.

[0059] When installing the installation device for the horizontal pipe, vertical pipe, and heating and cooling pipe, the environment and the installer should be kept clean, and the numbers of the telescopic hanger 1, the sliding bracket 2, etc. should be checked to prevent rework caused by installation errors. The sliding bracket 2 should be installed on the solid structure of the building, such as a beam or a shear wall. The slider 5 is embedded in the annular pipe support 203, and the spacing between adjacent sliders 5 is kept within 60 mm. Each slider 5 is arranged at an equal distance, and the length of the slider 5 is determined according to the maximum distance allowed for the vertical pipe to move. The ring sleeve 202 drills two semicircular holes up and down at the corresponding position of the installation ball 6 as a steel ball nest. When installing, first apply grease in the steel ball nest or on the surface of the ball 6, and then embed the ball 6 into the steel ball nest. In order to ensure that the ball 6 does not fall off during installation, a magnet can be placed at the steel ball nest position outside the ring sleeve 202, and the magnet can be removed after the installation is completed.

[0060] When installing the cold and heating pipes, first connect and weld some horizontal pipes, vertical pipes or elbows, then install valves and various instruments (such as pressure gauges) on the pipes, and then assemble them on the telescopic hanger 1 and sliding bracket 2. However, the weight and lifting capacity of the cold and heating pipes after assembly must be fully considered to ensure safety and efficiency. The supply and return water cold and heating pipes should not be installed at the same elevation, with the supply water on the top and the return water on the bottom. This will not only minimize the mutual influence of the surface temperature of the cold and heating pipes on the temperature inside the pipes, but also prevent the pipes from turning over each other at the tee, avoiding air blockage and reducing hydraulic losses.

[0061] The water pressure test of the cooling and heating pipes requires clean, non-corrosive water, such as city tap water. The test requires a special pressure test pump, two 1.6-level pressure gauges (the maximum pressure value of the gauge is about twice the test pressure), a calibrated safety valve (the calibration pressure of the safety valve is the strength test pressure plus 0.02MPa), a check valve, a stop valve, and the required water inlet and drain pipes. The pressure test is based on the system's low pressure. When the pressure reaches 30% of the test pressure, the pressure rise rate should be controlled and should not be too fast. The strength test time is controlled within 10 minutes, and multiple strength tests are prohibited. The tightness test pressure is the same as the designed working pressure, the test time is more than 2 hours, and the test data is based on meeting the design and specifications. After the water pressure test is passed, the cooling and heating pipes are painted with anti-corrosion paint. After the paint is dry, the cooling and heating pipes are flushed and the pipes are insulated.

[0062] After the water pressure test, the pressure is reduced but the water is not released. A magnetic ultrasonic vibrator set is placed next to the weld of the heating and cooling pipes. The spacing between the ultrasonic vibrators is less than 100 mm. The ultrasonic generator is turned on and runs for 4-5 minutes. During this period, a rubber hammer is used to knock near the weld of the heating and cooling pipes to vibrate off the attachments adsorbed on the weld in the pipe. Then the water pump is used to self-circulate for 1 hour, and then water is filled while draining until the water is clear. After that, the filter at the water inlet of the water pump is removed and cleaned, and finally the heating and cooling pipes are filled with clean water. When flushing, the water volume should exceed 70% of the rated working flow.

[0063] Since the flange bolts of the cold and heating pipes will expand during hot operation, the flange connection will become loose, which is very likely to leak. Therefore, the flange bolts of the cold and heating pipes must be further tightened during hot operation to ensure long-term continuous normal operation. After the flange bolts are tightened, the part is insulated. During the insulation process, the flange is covered with an outer shell and the inner shell is filled with insulation material.

[0064] After the insulation is completely completed and the outdoor temperature reaches the hottest season of the year, the chilled water test operation can be carried out until it meets the design requirements and acceptance specifications. After normal operation in summer and winter, the five parties will be organized to conduct acceptance and handover.
