Description

Technical Field

[0001] The utility model relates to the technical field of temperature control valves, in particular to a temperature control valve body structure. Background Art

[0002] The main purpose of the temperature control valve is to control occasions that require flow and temperature regulation in heating systems, air conditioning systems, water supply systems, industrial process control, etc. For example, a temperature control valve is installed on the inlet pipe of the radiator, and the indoor temperature is controlled by controlling the hot water flow rate through the temperature control valve.

[0003] Publication No. CN 218094266 U discloses a constant temperature radiator valve. By setting a limit gear sleeve in the regulating valve sleeve, it can engage with the convex teeth at the top of the valve body under its own weight, applying resistance to the rotation of the regulating valve sleeve, not affecting manual rotation, but avoiding the regulating valve sleeve from being pushed and rotated when the temperature control valve core shakes under the impact of unstable water flow during operation, that is, it can avoid the self-change of the adjustment angle of the regulating valve sleeve resulting in non-constant temperature.

[0004] Publication No. CN 211344039 U discloses a temperature control valve. When the plug seals the second water inlet end, it can be used as a straight-through temperature control valve. When the plug seals the first water inlet end, it can be used as an angle-type temperature control valve, combining the functions of a straight-through temperature control valve and an angle-type temperature control valve. There is no need to distinguish when selecting, avoiding the problem of incorrect selection, which is very convenient and practical.

[0005] In the above-mentioned prior art, during use, it is necessary to rotate the regulating valve sleeve on the temperature control valve, so that the regulating valve sleeve moves downward to squeeze the regulating valve rod, and the regulating valve rod drives the valve plug to move, thereby adjusting the hot water flow rate and achieving the effect of temperature control. However, in actual use, every time the radiator is opened, it is necessary to rotate the regulating valve sleeve and adjust it to a suitable position. When closing, it is also necessary to rotate the regulating valve sleeve in the reverse direction. The operation is cumbersome. Moreover, since the regulating valve sleeve and the pipeline on the temperature control valve body are threadedly connected, frequent rotation will cause wear and slipping of the teeth, affecting its service life. Summary of the Utility Model

[0006] The purpose of this part is to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this part, the abstract of the specification and the title of the utility model of this application to avoid obscuring the purpose of this part, the abstract of the specification and the title of the utility model, and such simplifications or omissions shall not be used to limit the scope of the utility model.

[0007] In view of the above problems of a temperature control valve body structure, the present utility model is proposed.

[0008] Therefore, the purpose of the present utility model is to provide a temperature control valve body structure, which is used to solve the problems that every time the radiator is opened, the regulating valve sleeve needs to be rotated and adjusted to a suitable position, and when it is closed, the regulating valve sleeve needs to be rotated in the reverse direction again. The operation is cumbersome, and since the pipeline on the regulating valve sleeve and the temperature control valve body is threadedly connected, frequent rotation will cause wear and the phenomenon of slipping teeth, affecting its service life and other issues.

[0009] To solve the above technical problems, the present utility model provides the following technical solutions: A temperature control valve body structure, comprising:

[0010] A main body unit, which includes a valve body, and connecting pipes are fixedly connected and communicated on both the left and right sides of the valve body;

[0011] An adjusting unit, which includes three baffles fixed inside the valve body. A gap is formed between adjacent two baffles. A first partition plate and a second partition plate are respectively slidably connected in the two gaps. A plurality of through grooves are equidistantly arranged in the baffles. A plurality of first notches are equidistantly arranged in the first partition plate. A plurality of second notches are equidistantly arranged in the second partition plate. And the number of through grooves in a single baffle, the number of first notches in a single first partition plate, and the number of second notches in a single second partition plate are equal. A primary control component for controlling the movement of the first partition plate is arranged at the top of the baffle, and a secondary control component for controlling the movement of the second partition plate is arranged at the bottom of the baffle.

[0012] As a preferred scheme of the temperature control valve body structure of the present utility model, wherein: The primary control component includes a threaded pipe fixedly connected and communicated with the top of the baffle. A first rubber plug is jointly fixed between the top of the baffle and the threaded pipe. A control valve rod is hermetically slidably connected in the first rubber plug, and the bottom of the control valve rod is fixed to the first partition plate. A valve sleeve for abutting against the control valve rod is threadedly connected to the outside of the threaded pipe.

[0013] As a preferred scheme of the temperature control valve body structure of the present utility model, wherein: An annular sleeve is fixed in the middle of the control valve rod. The annular sleeve is slidably fitted in the threaded pipe. A first spring is sleeved outside the control valve rod, and one end of the first spring abuts against the annular sleeve, and the other end of the first spring abuts against the first rubber plug.

[0014] As a preferred scheme of the temperature control valve body structure of the present utility model, wherein: A plurality of first air holes are opened in the annular sleeve, and a plurality of second air holes are opened at the top of the valve sleeve.

[0015] As a preferred embodiment of the valve body structure of the temperature control valve of the present utility model, the following is provided: The secondary control assembly includes a second rubber plug fixed to the bottom of the baffle. A connecting rod is hermetically and slidably connected within the second rubber plug, and the top of the connecting rod is fixed to the second partition plate. A connecting plate is fixed to the bottom of the connecting rod. Two positioning holes are formed within the connecting plate. A limiting plate is fixed to the bottom of the baffle. A cylindrical tube is fixed to one side of the limiting plate. A positioning rod is slidably connected within both the cylindrical tube and the limiting plate, and the positioning rod can be inserted into the positioning holes.

[0016] As a preferred embodiment of the valve body structure of the temperature control valve of the present utility model, the following is provided: One end of the positioning rod is fixed with a pull rod, and the pull rod passes through the cylindrical tube and slides within the cylindrical tube. A second spring is sleeved outside the pull rod, and one end of the second spring abuts against the positioning rod, while the other end of the second spring abuts against the inner wall of the cylindrical tube.

[0017] Advantages of the present utility model: Since the temperature change in a season does not undergo a huge change in the short term, generally the temperatures within several adjacent days are similar. That is, by rotating the valve sleeve to adjust the position of the first partition plate, the hot water flow rate in the near future is maintained at an appropriate position. However, when it is necessary to use the radiator, pull the pull rod to move the positioning rod into the cylindrical tube, and then push the connecting plate upward to drive the second partition plate to move upward. When the second notch and the through slot completely coincide, hot water of the corresponding volume can be supplied at this time. When heating is not required, pull the connecting plate downward to drive the second partition plate to move downward. When the second notch and the through slot are misaligned, that is, the second partition plate blocks the hot water, thereby stopping the supply of hot water. This process is fast in operation and does not require rotating the valve sleeve again. This not only avoids wear between the valve sleeve and the threaded tube, but also when the temperature change in the near future is small, the position of the valve sleeve does not need to be changed. When it is necessary to supply heat or not, only the position of the second partition plate needs to be adjusted. Description of the Drawings

Detailed implementation manners

[0025] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific implementation manners of the present utility model will be given with reference to the accompanying drawings of the specification.

[0026] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0027] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0028] Furthermore, the present utility model is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present utility model, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally out of the general proportion, and the schematic diagrams are only examples, which should not limit the scope of protection of the present utility model herein. In addition, in actual production, three-dimensional spatial dimensions including length, width and depth should be included.

[0029] Refer to Figures 1-5, which is an embodiment of the present utility model, provides a temperature control valve body structure, which includes: a main body unit 100 and an adjustment unit 200;

[0030] Among them, the main body unit 100 includes a valve body 101, and connecting pipes 102 are fixedly connected and communicated on both the left and right sides of the valve body 101;

[0031] The adjustment unit 200 includes three baffles 201 fixed inside the valve body 101. A gap 202 is formed between two adjacent baffles 201. A first partition 203 and a second partition 204 are respectively slidably connected in the two gaps 202. A plurality of through slots 205 are equidistantly arranged in the baffle 201. A plurality of first notches 206 are equidistantly arranged in the first partition 203. A plurality of second notches 207 are equidistantly arranged in the second partition 204. And the number of through slots 205 in a single baffle 201, the number of first notches 206 in a single first partition 203, and the number of second notches 207 in a single second partition 204 are equal. A primary control assembly 208 for controlling the movement of the first partition 203 is arranged at the top of the baffle 201, and a secondary control assembly 209 for controlling the movement of the second partition 204 is arranged at the bottom of the baffle 201.

[0032] In addition, the primary control assembly 208 includes a threaded pipe 2081 fixedly connected and communicated with the top of the baffle 201. A first rubber plug 2082 is jointly fixed between the top of the baffle 201 and the threaded pipe 2081. A control valve rod 2083 is hermetically slidably connected in the first rubber plug 2082. And the bottom of the control valve rod 2083 is fixed to the first partition 203. A valve sleeve 2084 for abutting against the control valve rod 2083 is threadedly connected to the outside of the threaded pipe 2081. An annular sleeve 210 is fixed in the middle of the control valve rod 2083. The annular sleeve 210 is slidably fitted in the threaded pipe 2081. A first spring 211 is sleeved outside the control valve rod 2083. And one end of the first spring 211 abuts against the annular sleeve 210, and the other end of the first spring 211 abuts against the first rubber plug 2082. A plurality of first air holes 212 are opened in the annular sleeve 210, and a plurality of second air holes 213 are opened at the top of the valve sleeve 2084.

[0033] During use, rotate the valve sleeve 2084 to make it move downward. When the valve sleeve 2084 squeezes the control valve rod 2083 and drives the control valve rod 2083 to move downward, it drives the first partition 203 to move downward. By controlling the coincidence degree of the first notches 206 on the first partition 203 and the through slots 205 on the baffle 201, the flow rate of hot water can be adjusted. When the first notches 206 and the through slots 205 completely coincide, the hot water flow rate is the largest. When the first notches 206 and the through slots 205 are misaligned, that is, the first partition 203 seals the through slots 205, the supply of hot water stops.

[0034] In addition, the secondary control component 209 includes a second rubber plug 2091 fixed to the bottom of the baffle 201. A connecting rod 2092 is hermetically and slidably connected inside the second rubber plug 2091. The top of the connecting rod 2092 is fixed to the second partition plate 204. A connecting plate 2093 is fixed to the bottom of the connecting rod 2092. Two positioning holes 2094 are formed inside the connecting plate 2093. A limiting plate 2095 is fixed to the bottom of the baffle 201. A cylindrical barrel 2096 is fixed to one side of the limiting plate 2095. A positioning rod 2097 is slidably connected inside the cylindrical barrel 2096 and the limiting plate 2095 together, and the positioning rod 2097 can be embedded into the positioning hole 2094. One end of the positioning rod 2097 is fixed to a pull rod 214, and the pull rod 214 passes through the cylindrical barrel 2096 and is slidable inside the cylindrical barrel 2096. A second spring 215 is sleeved outside the pull rod 214, and one end of the second spring 215 abuts against the positioning rod 2097, and the other end of the second spring 215 abuts against the inner wall of the cylindrical barrel 2096.

[0035] During use, since the temperature change in a season does not change significantly in a short period, generally the temperatures in several adjacent days are similar. That is, by rotating the valve sleeve 2084 to adjust the position of the first partition plate 203 so that the hot water flow rate in the near future is maintained at an appropriate position. However, when the radiator needs to be used, first pull the pull rod 214 to drive the positioning rod 2097 to move, move the positioning rod 2097 into the cylindrical barrel 2096, and then push the connecting plate 2093 upward, so that the connecting plate 2093 drives the connecting rod 2092 and the second partition plate 204 to move upward. When the top of the second partition plate 204 abuts against the inner wall of the top of the baffle 201, at this time the second notch 207 and the through groove 205 completely coincide. Then release the pull rod 214, and the second spring 215 drives the positioning rod 2097 to move under the resilience force, so that the positioning rod 2097 is embedded into another positioning hole 2094, that is, the second partition plate 204 is fixed. At this time, hot water of the corresponding volume can be supplied. When heating is not required, pull the pull rod 214 to move the positioning rod 2097 into the cylindrical barrel 2096, and then pull the connecting plate 2093 downward, so as to drive the connecting rod 2092 and the second partition plate 204 to move downward. When the bottom of the second partition plate 204 abuts against the bottom of the baffle 201, at this time the second notch 207 and the through groove 205 are misaligned, that is, the second partition plate 204 blocks the hot water, thus stopping the hot water supply. This process is fast in operation and does not require rotating the valve sleeve 2084 anymore. It not only avoids the wear between the valve sleeve 2084 and the threaded pipe 2081, but also the position of the valve sleeve 2084 does not need to be changed in the near future. When heating is required, only the position of the second partition plate 204 needs to be adjusted.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered by the scope of the claims of the present invention.
