Description

Technical Field

[0001] The utility model relates to the technical field of kitchen and bathroom, in particular to a thermostatic valve. Background Art

[0002] The thermostatic valve has a thermal element inside, which can produce a telescopic effect under the action of water temperature, so as to control the water inlet ratio of cold water and hot water and achieve a constant temperature effect. The thermostatic valve generally has a cold water inlet, a hot water inlet and a mixed water outlet, and the cold water inlet and the hot water inlet are mostly arranged on the periphery of the thermostatic valve, while the mixed water outlet is arranged at the end of the thermostatic valve to avoid the over-concentration of the inlets and outlets. However, this distribution method will cause the end of the thermostatic valve to bear water pressure during use, and under the pushing action of the water pressure, the thermostatic valve may be pushed out of the installation cavity, resulting in the problem of unstable installation of the thermostatic valve. Summary of the Utility Model

[0003] The utility model aims to solve the above technical problems and proposes a thermostatic valve structure with stable installation.

[0004] A thermostatic valve, comprising a valve body, a thermal temperature regulating member and a temperature regulating switch, wherein,

[0005] An installation cavity is arranged inside the valve body, and a cold water inlet, a hot water inlet and a mixed water outlet are arranged on the periphery. The cold water inlet, the hot water inlet and the mixed water outlet are arranged in sequence along the axial direction of the valve body and are all communicated with the installation cavity, respectively used for introducing cold water, introducing hot water and discharging mixed water into the valve body.

[0006] The thermal temperature regulating member is telescopically installed in the installation cavity along the axial direction of the installation cavity, and a blocking member for isolating the cold water inlet and the hot water inlet is provided to prevent direct mixing of cold water and hot water and inability to control the mixing ratio. A water passing channel communicating the mixed water outlet and the cold water inlet is arranged at the end of the blocking member, and cold water can be mixed with hot water after passing through the water passing channel.

[0007] The temperature regulating switch is rotatably installed on the valve body, and one end extends into the installation cavity and is connected to drive the thermal temperature regulating member to reciprocate in the installation cavity. At the same time, driven by the thermal temperature regulating member, one end of the blocking member approaches the cold water inlet and reduces or blocks the communication between the cold water inlet and the water passing channel. At this time, the hot water ratio of the mixed water is large and the water temperature increases. Or, the other end approaches the hot water inlet and reduces or blocks the communication between the hot water inlet and the mixed water outlet. At this time, the cold water ratio of the mixed water is large and the water temperature decreases.

[0008] The thermostatic valve provided by the present utility model sets the cold water inlet, hot water inlet, and mixed water outlet on the circumference of the valve body, thereby avoiding the problem that the end of the thermostatic valve is pushed by hydraulic force during use after installation, improving the installation firmness of the thermostatic valve, and preventing water leakage or damage at the installation position of the thermostatic valve and spraying water during use.

The guide rod is axially telescopically installed in the guide hole of the installation cavity, one end is threadedly connected to the temperature adjustment handle, and the other end is connected to the thermosensitive temperature adjustment member. Thus, the temperature adjustment switch can convert the rotational movement into the axial movement of the thermosensitive temperature adjustment member.

[0010] Preferably, to avoid completely fixedly installing the thermosensitive temperature adjustment member and enable it to control the telescopic movement of the plugging member at different water temperatures, the temperature adjustment switch further includes a first spring and a second spring. The first spring is compressively arranged between the guide rod and one end of the thermosensitive temperature adjustment member, and the second spring is compressively arranged between the other end of the thermosensitive temperature adjustment member and the installation cavity.

[0011] Preferably, a support gasket is provided between the compression of the second spring and the end of the thermosensitive temperature adjustment member to improve the support stability of the second spring for the end of the thermosensitive temperature adjustment member.

[0012] Preferably, the valve body is provided with a plugging hole facing the second spring, and an adjusting plugging member is threadedly installed in the plugging hole. The end of the second spring abuts against the inner side of the adjusting plugging member. Thus, the pushing force of the second spring on the thermosensitive temperature adjustment member can be adjusted by adjusting the screwing depth of the adjusting plugging member.

[0013] Preferably, the plugging hole communicates with the installation cavity through a reduced hole, and the end of the thermosensitive temperature adjustment member is provided with a limiting head passing through the reduced hole, thereby preventing the end of the thermosensitive temperature adjustment member from swinging.

[0014] Preferably, the cross-section of the guide hole is hexagonal, and the guide rod is provided with a hexagonal head, which can prevent the guide rod from rotating.

[0015] Preferably, the plugging member is sleeved outside the thermosensitive temperature adjustment member and fixed by threads, which is easy to assemble.

[0018] As can be seen from the above description of the present invention, the present invention has the following beneficial effects:

[0019] The thermostatic valve provided by the present invention arranges the cold water inlet, hot water inlet, and mixed water outlet on the circumference of the valve body, thereby avoiding the problem of the end of the thermostatic valve being pushed by hydraulic force during use after installation, improving the installation firmness of the thermostatic valve, and preventing water leakage or damage and spraying at the installation position of the thermostatic valve during use;

[0020] The first spring and the second spring are provided to improve the flexibility of the thermosensitive temperature regulating member, making the temperature control of the thermostatic valve more accurate;

Detailed implementation manners

[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0033] Please refer to Figures 1 to 6 , a constant temperature valve, including a valve body 1, a thermosensitive temperature regulating member 2 and a temperature regulating switch 3, wherein,

[0034] An installation cavity 11 is arranged inside the valve body 1, and a cold water inlet 12, a hot water inlet 13 and a mixed water outlet 14 are arranged on the periphery. The cold water inlet 12, the hot water inlet 13 and the mixed water outlet 14 are arranged in sequence along the axial direction of the valve body 1 and are all communicated with the installation cavity 11, and are respectively used for introducing cold water, introducing hot water and discharging mixed water of the valve body 1.

[0035] In this embodiment, in order to reduce the forming difficulty of the valve body 1 and the assembly difficulty of the remaining components, the valve body 1 includes an upper shell 15 and a lower shell 16. The temperature regulating switch 3 and the mixed water outlet 14 are arranged at one end of the upper shell 15, and the cold water inlet 12, the hot water inlet 13 and the thermosensitive temperature regulating member 2 are arranged at one end of the lower shell 16. In addition, in order to increase the water output, there are four cold water inlets 12, hot water inlets 13 and mixed water outlets 14, and they are evenly arranged around the valve body 1.

[0036] The thermosensitive temperature regulating member 2 is axially telescopic and installed in the installation cavity 11 along the axial direction of the installation cavity 11, and a plugging member 21 for isolating the cold water inlet 12 and the hot water inlet 13 is provided to prevent the direct mixing of cold water and hot water and the inability to control the mixing ratio. Preferably, the plugging member 21 is sleeved outside the thermosensitive temperature regulating member 2 and fixed by threads, which is easy to assemble.

[0037] A water passing channel 211 communicating the mixed water outlet 14 and the cold water inlet 12 is arranged at the end of the plugging member 21, and cold water can be mixed with hot water after passing through the water passing channel 211.

[0038] The temperature control switch 3 is rotatably mounted on the valve body 1, and one end extends into the installation cavity 11 and is connected to drive the thermosensitive temperature control member 2 to reciprocate in the installation cavity 11. At the same time, driven by the thermosensitive temperature control member 2, one end of the plugging member 21 approaches the cold water inlet 12, and reduces or blocks the communication between the cold water inlet 12 and the water passage 211. At this time, the hot water proportion of the mixed water is large and the water temperature increases. Or, the other end approaches the hot water inlet 13 and reduces or blocks the communication between the hot water inlet 13 and the mixed water outlet 14. At this time, the cold water proportion of the mixed water is large and the water temperature decreases.

[0039] In this embodiment, the temperature control switch 3 includes a temperature control handle 31 and a guide rod 32. The temperature control handle 31 is rotatably mounted on the valve body 1, and one end extends into the installation cavity 11. A guide hole is formed in a section of the installation cavity 11 facing the temperature control switch 3. The guide rod 32 is axially telescopically mounted in the guide hole of the installation cavity 11. One end is threadedly connected to the temperature control handle 31, and the other end is connected to the thermosensitive temperature control member 2. Thus, the temperature control switch 3 can convert the rotational movement into the axial movement of the thermosensitive temperature control member 2. Preferably, the cross-section of the guide hole is hexagonal, and the guide rod 32 is provided with a head with a hexagonal cross-section to prevent the guide rod 32 from rotating.

[0040] To avoid fixedly installing the thermosensitive temperature control member 2 completely and enable it to control the telescopic movement of the plugging member 21 at different water temperatures. In one embodiment, the temperature control switch 3 further includes a first spring 33 and a second spring 34. The first spring 33 is compressively arranged between the guide rod 32 and one end of the thermosensitive temperature control member 2, and the second spring 34 is compressively arranged between the other end of the thermosensitive temperature control member 2 and the installation cavity 11.

[0041] In another embodiment, the valve body 1 is provided with a plugging hole 17 facing the second spring 34. An adjusting plugging member 18 is threadedly installed in the plugging hole 17. The end of the second spring 34 abuts against the inner side of the adjusting plugging member 18. Thus, the pushing force of the second spring 34 on the thermosensitive temperature control member 2 can be adjusted by adjusting the screwing depth of the adjusting plugging member 18. Preferably, the plugging hole 17 communicates with the installation cavity 11 through a reduced hole. The end of the thermosensitive temperature control member 2 is provided with a limiting head passing through the reduced hole, so as to prevent the end of the thermosensitive temperature control member 2 from swinging. In addition, a supporting gasket 19 is arranged between the compression of the second spring 34 and the end of the thermosensitive temperature control member 2 to improve the supporting stability of the second spring 34 on the end of the thermosensitive temperature control member 2.

[0042] The thermostatic valve provided by the present utility model arranges the cold water inlet 12, the hot water inlet 13 and the mixed water outlet 14 on the periphery of the valve body 1, so as to avoid the problem that the end of the thermostatic valve is pushed by hydraulic force during use after the thermostatic valve is installed, improve the installation firmness of the thermostatic valve, and avoid the situation of water leakage or damage at the installation position of the thermostatic valve and water spraying during use.
