Description

Technical Field

[0001] The utility model relates to the technical field of temperature control valves, in particular to a temperature control valve which is easy to install and adjust. Background Art

[0002] Temperature control valves, also known as temperature control valves, are a typical application of flow control valves in the field of temperature control. Their basic principle is to control the outlet temperature of heat exchangers, air conditioning units, or other heating and cooling equipment by controlling the inlet flow of primary hot (cold) media. When the load changes, the flow is adjusted by changing the valve opening to eliminate the impact of load fluctuations and restore the temperature to the set value. The existing technology has the following problems:

[0003] Because the existing temperature control valve mainly relies on threaded connection to rotate with the pipeline during installation, but the temperature control valve is large in size and has structures such as switch knobs, which makes the rotation process during installation inconvenient, affecting the installation efficiency. At the same time, the structure of the existing temperature control valve is fixed and cannot be freely adjusted in length. As a result, when the temperature control valve is replaced, the length is insufficient and the pipeline has to be externally connected again, which increases the cost. At the same time, the extra installation pipeline also increases the risk of water leakage. Utility Model Content

The front end of the temperature control valve pipeline 1 is fixedly connected with a water inlet pipeline 11 that passes through its inner cavity, the mounting mechanism 3 includes a threaded ring 31, the threaded ring 31 is threadedly connected to the inner ring of the water inlet pipeline 11, a limit plate 32 is fixedly installed on the front side of the outer wall of the threaded ring 31, the rear side of the limit plate 32 is overlapped with the front side of the water inlet pipeline 11, and the front end of the threaded ring 31 is provided with an adaptive sealing mechanism 3 3. The outer wall of the water inlet pipe 11 is sleeved with a mounting cylinder cover 34. A limit ring 35 is fixedly installed on the rear end of the inner ring of the mounting cylinder cover 34. The inner ring of the mounting cylinder cover 34 overlaps the outer wall of the limit plate 32. The front side of the limit ring 35 overlaps the rear side of the limit plate 32. A mounting threaded wall 36 is opened on the front side of the inner ring of the mounting cylinder cover 34.

The front end of the tapered tube 1 331 is fixedly connected to a tapered tube 2 332. Two rubber sealing rings 333 are fixedly bonded to the outer surfaces of the tapered tubes 1 331 and 332.

[0024] The integral temperature control valve pipeline 1 can control the inlet and outlet of hot and cold water through the temperature control knob 2. When the temperature control valve pipeline 1 needs to be installed, it is only necessary to first insert the tapered tube 1 331 and the tapered tube 2 332 at the front end of the threaded ring 31 into the inner wall of the pipeline at the water delivery end with the help of the rubber sealing ring 333 on its outer wall, and then slide the integral installation cylinder cover 34 forward on the outer wall of the water inlet pipeline 11, and use the installation threaded wall 36 to thread the threaded outer wall of the installation pipeline to tighten it. At the same time, the installation cylinder cover 34 can also use the limit ring 35 to press against the limit plate 32 to prevent it from falling off. The integral threaded ring 31 can also be disassembled and assembled using the threaded connection with the inner ring of the water inlet pipeline 11, which is convenient for replacement.

At the same time, since the tapered water outlet pipe 43 is fixedly connected to the inner circle of the fixed adjusting pipe 41, the extension of the extension pipe 44 does not hinder the water flow between the temperature control valve pipeline 1 and the connecting pipeline. At the same time, the extension pipe 44 can use the limiting slider 46 to slide in the limiting slide groove 45 to maintain the stability of expansion and contraction and prevent it from falling off. At the same time, the extension pipe 44 can be threadedly connected to the internal thread of the connecting pipeline with the help of the threaded docking wall 47, and when threadedly connected, the overall extension pipe 44 can also use the limiting slider 46 to limit the limiting slide groove 45 to prevent rotation.

[0027] like Figure 5 As shown, three positioning holes 411 are formed on the top of the fixed adjustment tube 41, and three threaded positioning holes 441 are formed on the front side of the top of the extension tube 44.

The bottom of the outer wall of the threaded locking rod 412 is threadedly connected to the inner circle of one of the three threaded positioning holes 441.

[0028] The three threaded positioning holes 441 opened at the top of the extension tube 44 correspond to the three positioning holes 411 opened at the top of the fixed adjustment tube 41, and can be extended in three sections in total. When extending, the threaded locking rod 412 is rotated and disassembled using the locking knob 413 to release the limit on the extension tube 44. After the extension tube 44 is extended, the threaded locking rod 412 is aligned with the positioning hole 411 on the rear side and inserted, and threadedly connected with the threaded positioning hole 441 on the front side of the top of the extension tube 44 to complete the fixation of the extension tube 44. The extension of the temperature control valve pipeline 1 can be finally completed without the need for an external extension tube.

[0029] The following is a detailed description of the working principle of the temperature control valve which is easy to install and adjust.

[0030] like Figure 1-5As shown, the integral temperature control valve pipeline 1 can control the inlet and outlet of hot and cold water through the temperature control knob 2. When the temperature control valve pipeline 1 needs to be installed, it is only necessary to first insert the tapered tube 1 331 and the tapered tube 2 332 at the front end of the threaded ring 31 into the inner wall of the pipeline at the water delivery end with the help of the rubber sealing ring 333 on its outer wall, and then slide the integral installation cylinder cover 34 forward on the outer wall of the water inlet pipeline 11, and use the installation thread wall 36 to thread the threaded outer wall of the installation pipeline to tighten it.

When replacing the temperature control valve pipe 1, if the length of the temperature control valve pipe 1 is not enough, the extension pipe 44 can be extended as a whole by pulling the extension pipe 44 in the annular expansion groove 42 opened at the rear end of the fixed adjustment pipe 41. At the same time, since the tapered water outlet pipe 43 is fixedly connected to the inner ring of the fixed adjustment pipe 41, the extension pipe 44 The extension of the temperature control valve pipeline 1 does not hinder the water flow between the temperature control valve pipeline 1 and the connecting pipeline. At the same time, the extension pipe 44 can maintain the stability of the extension and prevent it from falling off by using the limiting slider 46 to slide in the limiting slide groove 45. At the same time, the extension pipe 44 can be threadedly connected to the internal thread of the connecting pipeline with the help of the threaded docking wall 47, and the entire extension pipe 44 can also be limited in the limiting slide groove 45 by the limiting slider 46 during the threaded connection to prevent it from rotating. The three threaded positioning holes 441 opened at the top of the extension pipe 44 correspond to the three positioning holes 411 opened at the top of the fixed adjustment pipe 41, and a total of three sections can be extended. When extending, the threaded locking rod 412 is rotated and disassembled using the locking knob 413 to release the restriction on the extension pipe 44. After the extension pipe 44 is extended, the threaded locking rod 412 is inserted into the positioning hole 411 on the rear side and threadedly connected to the threaded positioning hole 441 on the front side of the top of the extension pipe 44 to complete the fixation of the extension pipe 44, and the extension of the temperature control valve pipeline 1 can be finally completed without the need for an external extension pipe.
