Description

Technical Field

[0001] This invention relates to the field of quick connection technology for flanged pipes, specifically to a quick-installation pipe flange clamp connection device and its control method. Background Technology

[0002] In modern construction projects, the requirements for quality are getting higher and higher, and the construction period is getting shorter and shorter. However, the number of construction workers is decreasing and their skill level is decreasing, which restricts the smooth completion of projects. In order to make up for the adverse effects of the number and quality of workers, more and more projects are seeking to apply new technologies, new materials and new equipment to improve construction quality and efficiency.

[0003] For example, in the current stage, the general method for connecting pipe flanges is to connect the flanges of two pipes together, then use bolts to pass through the flange holes and use nuts to fix them. Tightening will successfully connect the pipe flanges.

[0004] However, using bolt and nut connections generally requires tightening a combination of multiple bolts and nuts, which is not only inconvenient to operate, but also prone to loosening, resulting in low construction efficiency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a quick-installation pipe flange clamp connection device and its control method, aiming to solve the aforementioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A quick-install pipe flange clamp connection device includes:

[0008] Flange short pipe; and

[0009] Two pipe flanges are fixed to both sides of the flanged short pipe;

[0010] Multiple pairs of fixed bases are uniformly fixed in a ring on the side of the flange short pipe;

[0011] Multiple flange fastening devices are connected to fixed bases and correspond one-to-one with multiple pairs of fixed bases for fixing flanges;

[0012] Multiple positioning rods, which are wavy and fixed to the inner wall of the pipe flange;

[0013] The gasket groove is formed on the side of the pipe flange;

[0014] A rubber gasket, which is located inside the gasket groove.

[0015] Preferably, a sensor interface is provided on the side of the flange short pipe.

[0016] Preferably, the rubber gasket is an X-shaped rubber gasket.

[0017] Preferably, the flange fastening device includes:

[0018] The front handle is hinged to the fixed base via a pivot.

[0019] Folding handle, which is hinged to the front handle via a handle joint;

[0020] A limit rod is fixed to one end of the folding handle near the front handle.

[0021] Fastener adjustment component, which is hinged to the front handle via pivot two;

[0022] The fastener is L-shaped and connected to the fastener adjuster;

[0023] The spherical end, which is fixed to the end of the fastener away from the fastener adjustment part, is used to abut against the flange connection hole.

[0024] Preferably, the fastener has threads on its surface and a threaded hole in its adjusting member, and the fastener and the adjusting member are connected by the threads and the threaded hole.

[0025] The fastener has a cut surface on its side, and the cut surface has a scale.

[0026] Preferably, the side of the fixed base is provided with a self-locking groove, and a self-locking pin is fixed on the side of the folding handle away from the front handle, and the self-locking pin is adapted to the self-locking groove.

[0027] A control method for a quick-installation pipe flange clamp connection device includes the following steps:

[0028] Step 1: Connect the flange of the pipe to be connected to the flange of the fitting, and allow the positioning rod to enter the interior of the pipe to be connected;

[0029] Step 2: Rotate the fastener relative to the fastener adjustment component to adjust the exposed length of the fastener under the action of the thread and threaded hole to accommodate flanges of different thicknesses;

[0030] Step 3: Secure the spherical end of the fastener tightly to the flange hole of the pipe to be connected;

[0031] Step 4: Rotate the folding handle. When the folding handle and the front handle are in a straight line, the limit rod will press against the front handle and drive the front handle to rotate. This will drive the fastener adjustment piece and the fastener to move. Finally, the ball end will press the flange of the pipe to be connected against the side of the pipe fitting flange to complete the connection and fixation. The connection will be sealed by the rubber gasket.

[0032] Step 5: Rotate the folding handle in the opposite direction so that it rotates around the handle joint relative to the front handle until the self-locking pin enters the self-locking groove to complete the locking, thereby preventing the front handle from popping up and becoming loose due to pipe vibration;

[0033] Once all flange fastening devices have been installed, the connection is complete.

[0034] Preferably, during the rotation of the front handle and the folding handle, after the front handle has rotated past its highest point, their relative forces will cause the front handle to move closer to the flange short pipe, thereby maintaining stability after fixing.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] The present invention provides a quick-installation pipe flange clamp connection device and its control method, which is suitable for prefabrication and convenient assembly of pipeline projects. Due to the convenience of assembly and connection, it greatly improves construction efficiency, reduces the number of on-site workers, speeds up the construction progress, and improves the construction quality.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] In the embodiments of this application, please refer to Figure 1 , 2 3. A quick-installation pipe flange clamp connection device, comprising a flange short pipe 1, wherein the flange short pipe 1 is provided with, but not limited to, 4 or 8 sets of fixing bases 3 with self-locking grooves 12 for hinged flange fastening devices. The 4 sets of fixing bases 3 and flange fastening devices are used for single-sided pipe flange connections, and the 8 sets of fixing bases 3 and flange fastening devices are used for double-sided pipe flange connections. The 8-set structure is as follows: Figure 4 As shown, the flange fastening device includes a fastener adjustment component 5, a fastener 6 with a ball end 8, a scale 7, a front handle 9, a folding handle 10, a limit rod 11, a self-locking pin 13, a rotating shaft 14, a rotating shaft 2 15, and a handle joint 16. The inner wall of the pipe flange 2 is welded with multiple positioning rods 19, and a gasket groove 17 for placing rubber gaskets 18 is opened on the side. By pressing down the front handle 9 and the folding handle 10, the ball end 8 of the fastener 6 is tightly fastened to the flange hole of the flange pipe or valve component, so as to achieve the purpose of quick assembly of the flange pipe system.

[0045] Please see Figure 1 and 2 The flange short pipe 1 can also be equipped with a sensor interface 4. The sensor interface 4 is used to install flow meters, thermometers, pressure gauges or corresponding sensors. The size and style of the sensor interface 4 can be the industry standard. When no sensor is needed, it can be sealed with a plug. The flange short pipe 1 serves as the main body of the connecting device between flange pipes, fittings and valve components. It is supplemented by flange fastening devices to form a flange connection pipe system, similar to the use of clamp connection in a grooved connection pipe system.

[0046] Please see Figure 1 , 23, 4, and 5, the flange fastening device includes a fastener adjustment component 5, a fastener 6 with a spherical end 8, a scale 7, a front handle 9, a folding handle 10, a limit rod 11, a self-locking pin 13, a rotating shaft 14, a rotating shaft 2 15, and a handle joint 16. The front handle 9 is hinged to the fixed base 3 via the rotating shaft 14, and the folding handle 10 is hinged to the end of the front handle 9 via the handle joint 16. The fastener adjustment component 5 is hinged to the front handle 9 via the rotating shaft 2 15 and has a threaded hole inside. The fastener 6 has threads on its surface and is set on the fastener adjustment component 5 through the threads and threaded hole. One side of the fastener 6 has a small flat surface with a scale 7, and the front end is fixed with a spherical end 8. The fastening device structure achieves convenient and labor-saving operation. The fastener adjustment component 5 meets the fastening requirements of flanges of different thicknesses. The fastener 6 with the scale 7 ensures uniform force on the flange surface, and the spherical end 8 achieves a firm locking purpose.

[0047] The rubber gasket 18 is an X-shaped rubber gasket, which is not easy to fall off when installed in the gasket groove 17. At the same time, the top of the X-shaped rubber gasket 18 forms a double leak-proof ring between the two flanges 2 and the pipe to be connected under the pressure of the two flanges, which enhances the tightness of the flange connection.

[0048] The positioning rod 19 is made of stainless steel round steel in a wave shape and is symmetrically welded and fixed in four directions inside the flange fitting. The raised part is higher than the inner surface of the pipe. The positioning rod 19 elastically limits the flange pipe section or valve component to be assembled to the same axis as the device, which facilitates assembly and installation and ensures that the flange is aligned.

[0049] Please see Figure 1 , 2 3 and 4, the fixed base 3 is provided with a self-locking groove 12, the tail of the folding handle 10 is fixed with a self-locking pin 13, and the head is fixed with a limit rod 11. After the device is assembled with the flange pipe or valve component, the folding handle 10 rotates backward around the handle joint 16 until the limit rod 11 abuts against the end of the front handle 9, forming a handle pressing down to fasten the flange pipe. After the fastening is completed, the folding handle 10 rotates forward around the handle joint 16 until the self-locking pin 13 is engaged in the self-locking groove 12, restricting the front handle 9 from moving upward, and avoiding the front handle 9 from popping up due to pipe vibration, which would cause the flange pipe or valve component to loosen.

[0050] The implementation process of this invention is as follows: The flange pipe is installed and fixed on the bracket. According to the thickness of the flange pipe and the flange thickness of the subsequent flange pipe or valve component, all the fixing rods 6 on the same side are adjusted to the appropriate scale according to the scale 7. Then, the four positioning rods 19 are inserted into the flange pipe or valve component to be assembled. The fasteners 6 are flipped down and the ball end 8 is aligned with the flange hole of the flange pipe or valve component to be assembled. The folding handle 10 is rotated backward around the handle joint 16 until the limit rod 11 presses against the end of the front handle 9, forming a long handle pressing down to tighten the flange pipe. After tightening, the folding handle 10 is rotated forward around the handle joint 16 until the self-locking pin 13 is engaged in the self-locking groove 12, restricting the upward movement of the front handle 9 and preventing the front handle 9 from popping up due to pipe vibration, which would cause the flange pipe or valve component to loosen. Then, the subsequent pipe section or valve component is assembled and connected according to the construction drawings. The installation of the pipeline system is thus completed.

[0051] A control method for a quick-installation pipe flange clamp connection device includes the following steps:

[0052] Step 1: Connect the flange of the pipe to be connected to the flange 2 of the fitting, and make the positioning rod 19 enter the interior of the pipe to be connected;

[0053] Step 2: Rotate the fastener 6 relative to the fastener adjustment component 5. Adjust the exposed length of the fastener 6 under the action of the thread and threaded hole to adapt to flanges of different thicknesses. The scale 7 indicated by different fasteners 6 after rotation must be the same.

[0054] Step 3: Secure the ball end 8 of fastener 6 to the flange hole of the pipe to be connected.

[0055] Step 4: Rotate the folding handle 10. When the folding handle 10 is in a straight line, the limit rod 11 will press against the front handle 9 and drive the front handle 9 to rotate. This will drive the fastener adjustment piece 5 and the fastener 6 to move. Finally, the ball end 8 will press the flange of the pipe to be connected against the side of the pipe flange 2 to complete the connection and fixation. The rubber gasket 18 will seal the connection.

[0056] During the rotation of the front handle 9 and the folding handle 10, after the front handle 9 has rotated past its highest point, their relative force will cause the front handle 9 to move closer to the flange short pipe 1, thereby maintaining the stability after fixing.

[0057] Step 5: Rotate the folding handle 10 in the opposite direction so that it rotates around the handle joint 16 relative to the front handle 9 until the self-locking pin 13 enters the self-locking groove 12 to complete the restraint, thereby preventing the front handle 9 from popping up due to pipe vibration and causing loosening.

[0058] Once all flange fastening devices have been installed, the connection is complete.
