Description

A heating temperature control valve Technical Field

[0001] This utility model relates to the field of temperature control valve technology, specifically a heating temperature control valve. Background Technology

[0002] Temperature control valves (also known as thermostatic valves or temperature regulating valves) are valves that automatically adjust their opening degree or switch on / off states based on the temperature of the medium. They are widely used in industrial process control, heating, ventilation and air conditioning (HVAC), energy management and other fields. Among them, mechanical thermostatic valves use thermal expansion materials (such as paraffin wax packs) to sense temperature. When the temperature changes, the volume expands / contracts, which pushes the valve core to move.

[0003] Most temperature control valves on the market currently use threaded connections to connect to pipelines. While this connection is simple, the lengths of temperature control valves from different manufacturers and models vary. Therefore, when a temperature control valve malfunctions and needs replacement, customers need to purchase a new one that matches the length of the original valve. This process is time-consuming and prone to errors. Therefore, to accommodate different installation spacings, a heating temperature control valve is provided. Summary of the Invention

[0004] The purpose of this utility model is to provide a heating temperature control valve in order to solve the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heating temperature control valve, comprising a temperature control valve, wherein the temperature control valve comprises a valve body, a fixing nut, a contraction tube, and a side-convex tube;

[0006] The fixing nut and the shrink tube are fixed at both ends of the valve body, the side-convex tube is fixed at the other end of the shrink tube, and an adjustable connection component is provided on the outside of the shrink tube. The fixing nut and the adjustable connection component are used to connect the temperature control valve with the two sections of pipeline.

[0007] The adjustable connection assembly includes a connecting screw, an annular mounting groove, an annular sealing adhesive layer, and a corrugated expansion adhesive layer.

[0008] The connecting screw is sleeved on the outside of the convex tube and protrudes to the other end of the convex tube. The annular mounting groove is formed on the inside of the connecting screw. The annular sealing layer is fixed on the inside of the annular mounting groove. The inner wall of the annular sealing layer is tightly fitted to the outer wall of the large-diameter end of the convex tube.

[0009] The corrugated expansion adhesive layer is fixed to one end of the inner side of the annular sealing adhesive layer, and the two ends of the corrugated expansion adhesive layer are tightly fitted to one end of the large diameter end of the side convex tube and the inner wall of the annular mounting groove away from the opening of the connecting screw tube, respectively.

[0010] The connecting screw moves horizontally along the outer wall of the convex tube to match the different spacing between the two sections of the pipe. The annular sealing layer and the corrugated expansion layer are used to achieve the sealing operation between the connecting screw and the convex tube.

[0011] As a further embodiment of this utility model: an L-shaped sealing ring is provided at the end of the connecting screw tube away from the port. The L-shaped sealing ring is sleeved on the outside of the convex tube and passes through the gap between the connecting screw tube and the convex tube and is fixedly connected to the corrugated expansion adhesive layer.

[0012] The outer wall of the small-diameter tube of the convex tube is formed with external threads. The convex tube is connected to a locking nut through the external threads. The locking nut is pressed against the end face of the L-shaped sealing ring to limit the position of the connecting tube.

[0013] As a further improvement of this utility model: the corrugated stretchable adhesive layer has a double-layer corrugated structure, and the double-layer corrugated structure has a cavity structure in the middle.

[0014] As a further embodiment of this utility model: the outer wall of the connecting screw tube is formed with an external thread that matches the nut on the pipeline, and a polygonal block is fixed on the outer side of the end of the connecting screw tube away from the port.

[0015] As a further improvement of this utility model: the open end of the convex tube is fixed with a tapered opening, and the outer wall of the tapered opening is tightly fitted with the inner wall of the corrugated stretchable adhesive layer.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] By setting an adjustable connection component, the distance between the connecting solenoid and the fixing nut can be adjusted through the extension and retraction of the connecting solenoid. This allows for connection to two pipe sections with different spacings. Compared to temperature control valves with fixed lengths on the market, this temperature control valve has a wider range of installation spacing and greater versatility, making it easier for customers to purchase and replace faulty temperature control valves of different lengths. At the same time, the triple sealing structure consisting of an annular sealing layer, a corrugated expansion layer, and an L-shaped sealing ring ensures a good sealing effect between the connecting solenoid and the side-convex pipe, preventing leakage.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please refer to Figures 1 to 4. In this embodiment of the present invention, a heating temperature control valve includes a temperature control valve 1. The temperature control valve 1 includes a valve body 101, a fixing nut 102, a shrink tube 103, and a side-convex tube 104.

[0025] The fixing nut 102 and the shrink tube 103 are fixed at both ends of the valve body 101, and the side-convex tube 104 is fixed at the other end of the shrink tube 103. An adjustable connection component 2 is provided on the outside of the shrink tube 103. The fixing nut 102 and the adjustable connection component 2 are used to connect the temperature control valve 1 with the two sections of pipeline.

[0026] The adjustable connection assembly 2 includes a connecting screw tube 201, an annular mounting groove 202, an annular sealing adhesive layer 204, and a corrugated expansion adhesive layer 205;

[0027] The connecting screw tube 201 is sleeved on the outside of the convex tube 104 and protrudes to the other end of the convex tube 104. The annular mounting groove 202 is formed on the inside of the connecting screw tube 201. The annular sealing layer 204 is fixed on the inside of the annular mounting groove 202. The inner wall of the annular sealing layer 204 is tightly fitted with the outer wall of the large diameter end of the convex tube 104.

[0028] The corrugated expansion adhesive layer 205 is fixed to one end of the inner side of the annular sealing adhesive layer 204, and the two ends of the corrugated expansion adhesive layer 205 are tightly fitted to one end of the large diameter end of the side convex tube 104 and the inner wall of the annular mounting groove 202 away from the opening of the connecting screw tube 201, respectively.

[0029] The connecting screw 201 moves horizontally along the outer wall of the side-convex tube 104 to match the different spacing between the two sections of the pipe. The annular sealing adhesive layer 204 and the corrugated expansion adhesive layer 205 are used to achieve the sealing operation between the connecting screw 201 and the side-convex tube 104.

[0030] An L-shaped sealing ring 206 is provided at the end of the connecting screw tube 201 away from the port. The L-shaped sealing ring 206 is sleeved on the outside of the side convex tube 104 and passes through the gap between the connecting screw tube 201 and the side convex tube 104 and is fixedly connected to the corrugated expansion adhesive layer 205.

[0031] The outer wall of the small-diameter tube of the side-convex tube 104 is formed with external threads. The side-convex tube 104 is connected to a locking nut 207 through the external threads. The locking nut 207 is pressed against the end face of the L-shaped sealing ring 206 to realize the position limit of the connecting screw tube 201.

[0032] The outer wall of the connecting screw tube 201 is formed with an external thread that matches the nut on the pipeline, and a polygonal block 203 is fixed on the outer side of the end of the connecting screw tube 201 away from the port.

[0033] In this embodiment: During installation, the temperature control valve 1 can adjust the distance between the connecting screw tube 201 and the fixing nut 102 by adjusting the extension and retraction of the connecting screw tube 201. This allows it to be connected to two pipe sections with different distances. Compared with the fixed length temperature control valves on the market, this temperature control valve 1 has a wider range of installation distances and is more versatile, making it easier for customers to purchase and replace faulty temperature control valves of different lengths.

[0034] When the connecting screw tube 201 is stretched and moved, the corrugated expansion adhesive layer 205 is squeezed, bent and contracted, which can fill and seal the gap between the outer wall of the side convex tube 104 and the annular sealing adhesive layer 204. At the same time, the annular sealing adhesive layer 204 is tightly attached to the outer wall of the large diameter end of the side convex tube 104, which can maintain a good sealing effect. After the connecting screw tube 201 is connected and fixed to the nut on the pipeline, by tightening the locking nut 207, the locking nut 207 is tightly squeezed against the L-shaped sealing ring 206. This not only fixes the position of the connecting screw tube 201, but also seals the gap between the connecting screw tube 201 and the outer wall of the side convex tube 104 by the deformation of the L-shaped sealing ring 206 under force.

[0035] The triple sealing structure described above ensures a good seal between the connecting screw tube 201 and the side-convex tube 104, preventing leakage.

[0036] Please refer to Figures 2-4 for details. The corrugated stretchable adhesive layer 205 has a double-layer corrugated structure, and there is a cavity structure in the middle of the double-layer corrugated structure.

[0037] In this embodiment: the air inside the cavity in the middle of the double-layer corrugated structure of the corrugated stretchable adhesive layer 205 gives the corrugated stretchable adhesive layer 205 good support strength, and when the corrugated stretchable adhesive layer 205 shrinks and deforms, the internal air is compressed, which allows the corrugated stretchable adhesive layer 205 to better fit with the outer wall of the side-convex tube 104 and the inner wall of the annular sealing adhesive layer 204, thereby improving the sealing effect.

[0038] It should also be noted that when the corrugated stretchable adhesive layer 205 is in its initial state, the crests of the corrugated structure on the upper and lower sides of the corrugated stretchable adhesive layer 205 are respectively attached to the inner wall of the annular sealing adhesive layer 204 and the outer wall of the side-convex tube 104, thus achieving a sealing effect.

[0039] Please refer to Figures 2-3. The open end of the convex tube 104 is fixed with a conical opening 105. The outer wall of the conical opening 105 is tightly fitted with the inner wall of the corrugated stretchable adhesive layer 205.

[0040] In this embodiment, the conical opening 105 facilitates the flow of fluid, allowing it to flow smoothly.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
