Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a regulating valve replacement device for a heat exchanger. Background Art

[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid. It is also called a heat exchanger. The regulating valve on the heat exchanger is used to control the pressure and pressure difference. At the same time, it has an automatic water replenishment function and can be used for variable frequency water replenishment.

[0003] The regulating valve is installed on the fluid delivery pipe of the heat exchanger. However, its bottom has no support. When installing or disassembling it, one person needs to hold the regulating valve to support it, and then another person needs to disassemble or install the regulating valve, which is cumbersome to operate. At the same time, due to the thermal expansion of the pipe after use, its end clamps the regulating valve tightly, so the regulating valve is very difficult to remove during replacement, making it difficult to replace.

DETAILED DESCRIPTION

[0019] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0020] See also Figure 1-3This embodiment provides a technical solution: a device for replacing a regulating valve for a heat exchanger, comprising a mounting base 1 and a regulating valve body 5. A heat exchanger fluid delivery pipe 2 is fixed to the side of the mounting base 1. The regulating valve body 5 is mounted on the inner bottom of the mounting base 1 via a second bolt 6. A flange 7 is connected to the port of the regulating valve body 5 via a first bolt 4. The flange 7 is connected to the heat exchanger fluid delivery pipe 2 via a flexible pipe 8. An adjustment mechanism 3 for adjusting the position of the flange 7 is mounted on the mounting base 1. During installation, the regulating valve body 5 is first fixed to the mounting base 1 via the second bolt 6. This prevents the regulating valve body 5 from shaking when the flange 7 is installed. At the same time, the flange 7 can support the regulating valve body 5, thereby avoiding the trouble of requiring multiple people to replace the regulating valve body 5. The device is easy to replace and convenient to use. During disassembly, the flange 7 and the port position of the regulating valve body 5 are first disassembled. Then, the flange 7 is returned to its original position via the adjustment mechanism 3. Finally, the regulating valve body 5 is removed from the mounting base 1.

[0021] The flexible tube 8 is a bellows having expansion and contraction compensation capabilities, which prevents the pipe from clamping the regulating valve body 5 too tightly during disassembly, thereby ensuring convenience in replacement.

[0022] The adjusting mechanism 3 includes a transmission seat 33 and a slide 35. The slide 35 is opened on the top beam of the mounting seat 1.
