Description

Technical Field

[0001] The utility model belongs to the technical field of self-operated balancing valves, and in particular relates to a labor-saving self-operated balancing valve. Background Art

[0002] Existing self-operated balancing valves operate without external energy. They automatically adjust their opening based on changes in the pressure, temperature, or flow of the medium flowing through the valve to maintain the system's pressure, flow, or temperature within a set range. Self-operated balancing valves are widely used in heating systems, air conditioning systems, industrial pressure control, and the petroleum industry.

[0003] Usually when installing a self-operated balancing valve, flange connection becomes a common connection method for self-operated balancing valves due to its standardization, high strength, easy maintenance, strong adaptability and high safety. When connecting, the flange welded on the self-operated balancing valve is butted against the flange of the installation pipe, and then the holes are aligned. After the holes are aligned, the corresponding bolts are inserted into the corresponding holes and locked to complete the connection.

[0004] However, in actual connections, when installing balancing valves in some small and restricted spaces (such as urban underground pipe networks, internal piping systems of some buildings, special industrial applications, etc.), due to limited space or obstructed vision, it is necessary to repeatedly align the holes during installation, which requires a lot of manpower during installation and reduces installation efficiency.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a labor-saving self-operated balancing valve.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] A labor-saving self-operated balancing valve includes a self-operated balancing valve body, two external pipes fixedly connected to both sides of the self-operated balancing valve body, flanges fixedly connected to opposite ends of the two external pipes, push rings slidably fitted on the upper sides of the external pipes, vertical plates fixedly connected to the upper and lower sides of the push rings, and limiting blocks fixedly connected to one side of the plurality of vertical plates;

[0009] Two L-shaped plates are fixedly connected to the other side of two of the multiple vertical plates. Sliding openings are opened on one side of two of the multiple vertical plates. The inner wall of the sliding opening is slidably fitted with a locking pin, and a spring is fixedly connected between the locking pin and the L-shaped plate.

[0010] The labor-saving self-operated balancing valve according to the claim is characterized in that mounting grooves are provided on opposite sides of the two flanges, and sealing gaskets are installed on the inner walls of the mounting grooves.

[0011] Optionally, both external tubes are provided with an L-shaped sliding groove, and the inner wall of the L-shaped sliding groove is slidably fitted with a sliding block fixedly connected to the push ring.

[0012] Optionally, two hand-held plates are fixedly connected to one side of the two push rings, and a non-slip pad is fixedly connected to one side of the multiple hand-held plates.

[0013] Optionally, adjacent sides of the plurality of limiting blocks are configured to be in an arc shape that matches the flange, and one side of the plurality of limiting blocks is configured to be an inclined surface.

[0014] Optionally, two clamping pieces are fixedly connected to the inner walls of the two L-shaped chutes, and the two clamping pieces are bonded to the L-shaped chutes by waterproof glue.

[0015] Optionally, opposite sides of the two locking pins are both configured to be tapered.

[0016] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described below at the same time:

[0017] By setting a push ring, the limit block can be aligned with the edge of the flange and the external flange by pushing the push ring, and then the self-balancing valve body is rotated. During the process, the spring squeezes the locking pin. When the push ring is aligned with the hole of the external flange, the locking pin will be squeezed between the two by the spring, so that the flange can be aligned with the hole. The hole can be aligned by just pulling and turning, making it easier to align the hole in a small and confined space, reducing the time for hole alignment, improving efficiency, and saving manpower for hole alignment.

DETAILED DESCRIPTION

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] See also Figure 1-4 As shown, in this embodiment, a labor-saving self-operated balancing valve is provided, comprising a self-operated balancing valve body 1, two external pipes 2 being fixedly connected to both sides of the self-operated balancing valve body 1, flanges 3 being fixedly connected to opposite ends of the two external pipes 2, push rings 4 being slidably fitted on the upper sides of the external pipes 2, vertical plates 5 being fixedly connected to the upper and lower sides of the push rings 4, and limiting blocks 6 being fixedly connected to one side of the plurality of vertical plates 5;

[0029] The self-operated balancing valve body 1 is a common existing technology on the market and will not be described in detail.

[0030] Two L-shaped plates 7 are fixedly connected to the other side of two of the multiple vertical plates 5. Sliding openings 8 are opened on one side of two of the multiple vertical plates 5. The inner wall of the sliding opening 8 is slidably fitted with a locking pin 9. A spring 10 is fixedly connected between the locking pin 9 and the L-shaped plate 7.

[0031] The application of one aspect of this embodiment is as follows: when installing, the two flanges 3 are aligned with the corresponding reserved flanges, and then the pushing rings 4 are pushed to both sides by holding two hands, driving the limiting block 6 to be stuck in the reserved flange and the outer side of the flange 3, so that the edges between the two are aligned. However, the holes may deviate, and during the process, the locking pin 9 will pass through the hole in the pushing ring 4, and the locking pin 9 may not be aligned with the hole of the reserved flange. The locking pin 9 is squeezed by the reserved flange and the spring 10 will shrink. At this time, the self-operated balancing valve body 1 can be rotated to keep the locking pin 9 under the top pressure of the spring 10. When the holes are aligned, the locking pin 9 will be inserted into the hole of the reserved flange by the top pressure of the spring 10 to realize the hole alignment operation. No personnel observation is required, and the hole alignment can be realized by pulling and turning, which makes it easier to align the hole in a small and confined space, reduces the hole alignment time, improves efficiency, and saves manpower for hole alignment.

[0032] After the holes are aligned, the locking pin 9 is used to limit one of the holes of the push ring 4, and then the bolts are inserted into the other holes for fixation. When the fixation is completed, the push ring 4 is retracted in the reverse direction to make the locking pin 9 disengage from the hole originally inserted, and finally the holes are aligned for final fixation.

[0033] By setting the push ring 4, the limiting block 6 can be aligned with the edge of the flange 3 and the external flange by pushing the push ring 4, and then the self-balancing valve body 1 is rotated. During the process, the spring 10 squeezes the locking pin 9. When the push ring 4 is aligned with the hole of the external flange, the locking pin 9 will be squeezed into it by the spring 10, so that the flange can be aligned with the hole. The hole can be aligned by just pulling and turning, which makes it easier to align the hole in a small and confined space, reduces the time for aligning the hole, improves efficiency, and saves manpower for aligning the hole.

[0034] In this embodiment, mounting grooves 11 are provided on opposite sides of the two flanges 3, and sealing gaskets 12 are provided on the inner walls of the mounting grooves 11. By placing the sealing gaskets 12 in the mounting grooves 11, the gap between the flanges 3 can be sealed by squeezing the sealing gaskets 12 after installation.

[0035] The two external tubes 2 of this embodiment are both provided with an L-shaped groove 13. The inner wall of the L-shaped groove 13 is slidably matched with a sliding block 14 fixedly connected to the push ring 4. The L-shaped groove 13 is arc-shaped. When the push ring 4 is pushed to limit, it moves horizontally. When it moves to the side close to the self-balancing valve body 1, the push ring 4 can be rotated to make the locking pin 9 away from the hole of the flange 3, which is convenient for the final installation of the hole.

[0036] In this embodiment, two push rings 4 are fixedly connected to one side with two hand-held plates 15, and one side of multiple hand-held plates 15 is fixedly connected to an anti-slip pad 16, which makes it convenient for people to squeeze the anti-slip pad 16 with two fingers to push the push ring 4 to both sides when operating it.

[0037] The adjacent sides of the multiple limiting blocks 6 of this embodiment are set to an arc shape that matches the flange 3, and one side of the multiple limiting blocks 6 is set to a slope. When the limiting blocks 6 are mounted on the outer side of the flange 3, the arc shape allows the two limiting blocks 6 to limit the outer edge of the push ring 4. The slope allows the limiting blocks 6 to move from large to small, making it easier to align the push ring 4 with the external flange.

[0038] The inner walls of the two L-shaped chutes 13 of this embodiment are fixedly connected to two clamping pieces 17. The two clamping pieces 17 are bonded to the L-shaped chutes 13 by waterproof glue. When the sliding block 14 rotates, it is clamped with the clamping pieces 17 to achieve a simple clamping and fixing of the flipped L-shaped chutes 13, thereby reducing the vibration and noise of the sliding block 14 during use. The clamping pieces 17 are made of soft rubber and have a certain degree of elasticity.

[0039] The opposite sides of the two locking pins 9 of this embodiment are both configured to be tapered, and the tapered shape can be better inserted into the corresponding holes of the external flange.

[0040] The present invention is not limited to the above-described embodiments. Any structural changes made under the guidance of the present invention should be understood by anyone. Any technical solution that is the same or similar to the present invention falls within the scope of protection of the present invention. The technology, shape, and structure not described in detail in the present invention are all known technologies.
