Description

Technical Field

[0001] The utility model relates to the technical field of valve equipment, and in particular to a NB-Iot communication temperature control valve. Background Art

[0002] NB-lot has the characteristics of wide coverage, low power consumption, low cost, multiple connections, excellent architecture and high efficiency.

[0003] The temperature control valve is an indispensable regulating device in the heating system. The temperature control valve can adjust the indoor temperature according to the actual situation without causing excessive temperature difference. The existing electronic temperature control valve cannot achieve emergency protection. For example, if the temperature is too high, if the operator does not cool it down in time, it is easy to cause safety hazards. Utility Model Content

[0004] The utility model proposes an NB-Iot communication temperature control valve.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A NB-Iot communication temperature control valve comprises a temperature control valve and a NB-Iot communication device, wherein the temperature control valve comprises a main valve body, wherein two sides of the main valve body are respectively provided with a channel one and a channel two, wherein an electronic control valve is fixed in the main valve body, wherein the electronic control valve comprises a hose, wherein paraffin is loaded in the hose, wherein a heating device is fixed inside the hose, wherein the paraffin is solid at low temperature and melts and expands at high temperature, wherein a piston is slidably connected in the hose, wherein the piston is located at the top of the paraffin, wherein the melting and expansion of the paraffin drives the piston to move in the hose, wherein a sealing cover is sealed and fixed to the top end surface of the hose, wherein a main valve is arranged on an outer ring sleeve of the hose, wherein a base is fixed on the top of the sealing cover, wherein a push rod is arranged through the sealing cover and connected to the base, wherein the base is fixedly connected to the main valve body, wherein a lower bracket is fixed on the bottom end surface of the base, wherein a return spring is arranged between the lower bracket and the main valve, wherein a bypass valve is arranged on the outer ring sleeve of the hose, wherein the bypass valve can move on the hose, and a bypass valve spring is arranged between the bypass valve and the lower bracket.

[0007] Furthermore, the NB-Iot communication device includes a UART conversion control chip and a NB-Iot sub-function module that are connected to each other.

[0008] Furthermore, the lower bracket is provided with a through hole.

[0009] Furthermore, a liquid inlet pipe is provided on one side of the main valve body, and the liquid inlet pipe is connected to the main valve body.

[0010] Beneficial effects:

[0011] The utility model controls the electronic valve control valve through the NB-lot communication device, which greatly improves the intelligence level of the temperature control valve. The NB-lot communication device directly controls the heating device to heat the paraffin in the hose. The heating device can control the melting degree of the paraffin at any time, thereby controlling the opening degree between the main valve and the base.

[0012] The NB-lot communication device in the hose of the utility model controls the melting of paraffin by the heating device in real time. If the operator makes a mistake and ignores the rapid increase in temperature in the pipeline while the coolant flow is small, the paraffin will also melt rapidly under a long-term high temperature environment, increasing the cooling flow and realizing emergency cooling of the entire pipeline.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-3A NB-Iot communication temperature control valve comprises a temperature control valve 2 and a NB-Iot communication device 1, wherein the NB-Iot communication device 1 comprises a UART conversion control chip and a NB-Iot sub-function module connected to each other, wherein the temperature control valve 2 comprises a main valve body 3, wherein a channel 1 4 and a channel 2 5 are respectively arranged on both sides of the main valve body 3, wherein an electronic control valve 6 is fixed in the main valve body 3, wherein the electronic control valve 6 comprises a hose 8, wherein the hose 8 is loaded with paraffin 9, wherein a heating device 18 is fixed inside the hose 8, wherein the paraffin 9 is solid at low temperature, and the paraffin 9 melts and expands at high temperature, wherein a piston 10 is slidably connected in the hose 8, wherein the piston 10 is located at the top of the paraffin 9, and wherein the melting and expansion of the paraffin 9 drives the piston 10 in the hose 8. The rubber hose 8 moves in the inner ring 8, the top end face of the rubber hose 8 is sealed and fixed with a sealing cover 11, the outer ring of the rubber hose 8 is provided with a main valve 19, the top of the sealing cover 11 is fixed with a base 13, a push rod 12 is provided through the sealing cover 11 to connect the base 13, the base 13 is fixedly connected to the main valve body 3, a lower bracket 14 is fixed to the bottom end face of the base 13, a return spring 15 is provided between the lower bracket 14 and the main valve 19, the outer ring of the rubber hose 8 is provided with a bypass valve 17, the bypass valve 17 can move on the rubber hose 8, a bypass valve spring 16 is provided between the bypass valve 17 and the lower bracket 14, the lower bracket 14 is provided with a through hole 20, and a liquid inlet pipe 7 is also provided on one side of the main valve body 3, and the liquid inlet pipe 7 is connected to the main valve body 3.

[0020] Working principle: at low temperature, the main valve body 3 and the base 13 are in a sealed state, and the bypass valve 17 and the liquid inlet of the channel 2 5 are in an open state. At this time, the coolant enters the channel 2 5 from the liquid inlet pipe 7 to form a small circulation. During adjustment, the NB-lot communication equipment 1 receives the signal and the heating device 18 is started. The heating device 18 is started to heat the paraffin 9 in the hose 8. After the paraffin 9 is heated, it expands and pushes the piston 10 to move upward. Since the top of the push rod 12 is connected to the base 13, and the base 13 is fixedly connected to the main valve body 3, the piston 10 cannot move upward, and the bypass valve 17 is forced to move downward under the action of the reverse thrust. At this time, the main valve 19 is separated from the base 13 to open the bypass valve 17 and seal it with the pipe wall of the channel 2 5. At this time, the coolant flows directly into the channel 1 4 from the liquid inlet pipe 7. If the operator makes a mistake and ignores the rapid increase in temperature in the pipeline and the coolant flow is small, the paraffin 9 will also melt rapidly under a long-term high temperature environment to increase the cooling flow, thereby realizing emergency cooling of the entire pipeline.

[0021] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
