[0035] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0036] Please refer to Figures 1 to 5As shown, an embodiment of this utility model provides a high-pressure and high-temperature resistant secondary pipeline balancing valve, comprising: a pipeline balancing valve body 1, wherein detachable connecting pipes 3 are provided on both sides of the pipeline balancing valve body 1, and the connecting pipes 3 are fixedly connected to the pipeline balancing valve body 1 through an installation component 2;

[0037] By adopting the above technical solution, not only is the high pressure resistance and high temperature resistance of the main body 1 of the pipeline balance valve of this utility model increased by setting chromium-molybdenum steel, but also the installation component 2 is set to facilitate the docking and installation of the main body 1 of the pipeline balance valve of this utility model with the connecting pipe 3, thereby increasing the flexibility of the use of the main body 1 of the pipeline balance valve of this utility model.

[0038] Please refer to Figures 1 to 5 As shown, the main body 1 of the pipeline balancing valve is made of chromium-molybdenum steel alloy. By using chromium-molybdenum steel, the high pressure resistance and high temperature resistance of the main body 1 of the pipeline balancing valve of this utility model are increased.

[0039] Please refer to Figures 1 to 5 As shown, a sealing ring 202 is provided on the mounting base 201 at the position corresponding to the mounting head 2011. The sealing ring 202 increases the sealing performance of the connection between the mounting base 201 and the mounting head 2011.

[0040] Please refer to Figures 1 to 5 As shown, the installation assembly 2 includes a mounting base 201 fixedly connected to the main body 1 of the pipeline balance valve. The end of the connecting pipe 3 is provided with an installation head 2011 that cooperates with the mounting base 201. The mounting base 201, corresponding to the position of the installation head 2011, is also provided with a preliminary locking assembly 203 for initially fixing the installation head 2011. The installation head 2011, corresponding to the position of the preliminary locking assembly 203, has a slot 2031. The preliminary locking assembly 203 includes a mounting rod 204 fixedly connected to the mounting base 201. A sliding rod 2041 is slidably connected to the mounting rod 204. One end of the sliding rod 2041 is fixedly connected to an operating rod 2042, and a connecting spring 2042 is fixedly connected to the operating rod 2042. 43. The other end of the connecting spring 2043 is fixedly connected to the mounting rod 204, and the other end of the slide rod 2041 is fixedly connected to the positioning seat 2044. The positioning seat 2044 is fixedly connected to the locking block 2045 that matches the locking slot 2031. First, the mounting head 2011 on the side of the connecting tube 3 is inserted into the mounting seat 201. While the mounting head 2011 is inserted into the mounting seat 201, the inclined surface of the locking block 2045 is pressed, causing the locking block 2045 to retract. When the locking slot 2031 moves to the position of the locking block 2045, the locking block 2045 can be driven into the corresponding locking slot 2031 under the elastic force of the connecting spring 2043. Therefore, the connecting tube 3 can be conveniently positioned.

[0041] Please refer to Figures 1 to 5As shown, a positioning sleeve 205 matching the slide rod 2041 is provided on the mounting rod 204 at the position corresponding to the slide rod 2041. The positioning sleeve 205 limits the slide rod 2041, thereby increasing the stability of the slide rod 2041 sliding on the mounting rod 204. Limiting sliders 206 are fixedly connected to both sides of the positioning seat 2044. A limiting groove 2061 matching the limiting slider 206 is provided on the mounting seat 201 at the position corresponding to the limiting slider 206. The limiting slider 206 and the limiting groove 2061 limit the positioning seat 2044, thereby... The stability of the positioning seat 2044 driving the locking block 2045 into the slot 2031 is increased. The top and bottom of the mounting seat 201 are provided with fixing components 207 for fixing the connecting pipe 3. The fixing component 207 includes a fixing seat 2071 fixedly connected to the mounting seat 201. The fixing seat 2071 is fixedly connected to the side of the fixing bolt 2072. The connecting pipe 3 is fixedly connected to a fixing ear 2073 that matches the fixing bolt 2072. By inserting the fixing bolt 2072 into the corresponding fixing ear 2073, a stable connection between the pipeline balance valve body 1 and the connecting pipe 3 can be achieved.

[0042] The working principle of this utility model is as follows: not only by setting chromium-molybdenum steel, the high pressure resistance and high temperature resistance of the main body 1 of the pipeline balance valve of this utility model are increased, but also by setting the installation component 2, the installation head 2011 on the side of the connecting pipe 3 is first inserted into the mounting base 201. At the same time as the installation head 2011 is inserted into the mounting base 201, the inclined surface of the locking block 2045 is squeezed, causing the locking block 2045 to retract. When the locking groove 2031 moves to the position of the locking block 2045, under the elastic force of the connecting spring 2043, the locking block 2045 can be driven into the corresponding locking groove 2031, thus realizing the convenient positioning of the connecting pipe 3. Then, the fixing bolt 2072 is inserted into the corresponding fixing ear 2073, thereby realizing the stable connection between the main body 1 of the pipeline balance valve and the connecting pipe 3, which facilitates the docking and installation of the main body 1 of the pipeline balance valve of this utility model and the connecting pipe 3, thereby increasing the flexibility of the use of the main body 1 of the pipeline balance valve of this utility model.
