Description

Technical Field

[0001] The utility model relates to the technical field of temperature control ball valves, in particular to an intelligent temperature control ball valve. Background Art

[0002] The temperature control valve, abbreviated as the temperature control valve, is a typical application of the flow regulating valve in the field of temperature control. Its basic principle is to control the flow rate of the primary heat (cold) medium at the inlet of the heat exchanger, air conditioning unit or other heating and cooling equipment, so as to control the outlet temperature of the equipment. When the load changes, the flow rate is adjusted by changing the valve opening degree to eliminate the influence caused by the load fluctuation and restore the temperature to the set value.

[0003] The ball valve is a valve that drives the spherical closing member by the valve stem and rotates around the axis of the ball valve, and can be used for the regulation and control of fluids. The sphere of the ball valve is elastic, and both the sphere and the valve seat sealing ring are made of metal materials. The sealing specific pressure is very high, and it is impossible to achieve the sealing requirement only relying on the pressure of the medium itself, and external force must be applied. The ball valve is suitable for high-temperature and high-pressure media.

[0004] However, in the current market, in the fluid conveying pipeline, the metering system and the valve for controlling the on-off are usually two separate devices, that is, the metering system is designed separately in the pipeline, and the valve is designed at other positions of the pipeline. This not only makes the overall installation cost higher, but also easily leads to problems such as inaccurate metering. Content of the Utility Model

[0005] The utility model provides an intelligent temperature control ball valve, aiming to solve the existing problems.

[0006] The utility model is realized as follows. An intelligent temperature control ball valve includes a ball valve body and a total control center. A through pipe is fixedly connected to the middle of the side wall of the ball valve body. The top of the through pipe is fixedly communicated with an indicating disk. The indicating disk is circular ring-shaped and is wirelessly connected to the total control center. A valve stem is arranged in the through pipe. One end of the valve stem passes through the inner ring of the indicating disk and is connected to a driving mechanism for driving the valve stem to rotate. A valve core is arranged in the ball valve body. A groove is formed on the surface of the valve core facing the valve stem. The end of the valve stem far from the driving mechanism extends and is embedded in the groove of the valve core. A temperature sensor and a pressure sensor are inlaid and installed on the inner wall of the ball valve body. The temperature sensor and the pressure sensor are respectively arranged on both sides of the valve core, and both the temperature sensor and the pressure sensor are wirelessly connected to the total control center.

[0007] Preferably, an auxiliary liquid inlet pipe and an auxiliary liquid outlet pipe are fixedly communicated with the side wall of the ball valve body.

In addition, the total control center transmits the flow value to the indicating disk, and the pointer of the indicating disk rotates to display the flow value. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Reference Figures 1 to 2, the intelligent temperature-controlled ball valve includes: An auxiliary liquid inlet pipe 3 and an auxiliary liquid outlet pipe 4 are fixedly connected and communicated with the side wall of the ball valve body 1. The auxiliary liquid inlet pipe 3 and the auxiliary liquid outlet pipe 4 are used to assist in increasing the liquid inlet and outlet of the ball valve body 1. A through pipe is fixedly connected to the middle of the side wall of the ball valve body 1. The indicating disk 6 is circular. The top of the through pipe is fixedly connected and communicated with the indicating disk 6. A valve stem 7 is arranged in the through pipe. One end of the valve stem 7 passes through the inner ring of the indicating disk 6 and is connected with a driving mechanism 5. The driving mechanism 5 is used to drive the valve stem 7 to rotate. A valve core 8 is arranged in the ball valve body 1. A groove is formed on the surface of the valve core 8 facing the valve stem 7. The end of the valve stem 7 away from the driving mechanism 5 extends and is embedded in the groove of the valve core 8. The valve stem 7 drives the valve core 8 to rotate in the ball valve body 1, thereby controlling the flow rate in the ball valve body 1. A temperature sensor 9 and a pressure sensor 10 are embedded and installed on the inner wall of the ball valve body 1. The temperature sensor 9 and the pressure sensor 10 are respectively arranged on both sides of the valve core 8. The temperature sensor 9 and the pressure sensor 10 are both wirelessly connected to the central control center. The temperature sensor 9 is used to monitor the temperature of the fluid in the ball valve body 1 and transmit the obtained temperature to the central control center, facilitating the central control center to adjust the temperature of the fluid in the ball valve body 1. The pressure sensor 10 is used to monitor the pressure of the fluid in the ball valve body 1 and transmit the obtained pressure to the central control center, facilitating the central control center to calculate the flow rate in the ball valve body 1 based on the pressure, realizing the integration of the on-off valve and the metering system. The central control center transmits the calculation result to the indicating disk 6, and the pointer of the indicating disk 6 rotates to indicate the flow rate value. The two ports of the ball valve body 1 are respectively connected to the pipelines. Two sheaths 2 are fixedly connected to the outer walls at the two ports of the ball valve body 1. The two sheaths 2 are used to protect the connection between the two ports of the ball valve body 1 and the pipelines, avoiding problems such as deformation or damage at the interface due to impact, resulting in liquid leakage. A through hole is axially formed in the valve stem 7, and an alumina ceramic tube is fitted in the through hole. A resistance wire and a heat medium oil are arranged inside the alumina ceramic tube. The bottom of the alumina ceramic tube is matched and fitted with the groove of the valve core 8. The resistance wire is connected to the power supply of the driving mechanism 5, and it can actively adjust the temperature of the valve core 8 in combination with the change of the fluid temperature in the ball valve body 1. The heat is directionally transmitted by the alumina ceramic tube with good heat conduction performance, ensuring that the temperature of the valve core 8 is maintained at a suitable temperature and avoiding the problem that the valve core 8 cannot operate normally due to freezing.

[0020] Working principle: Hot water enters from the liquid inlet of the ball valve body 1, flows out from the liquid outlet after passing through the valve core 8. The temperature sensor 9 transmits the monitored water temperature to the master control center. When adjusting the flow rate, the driving mechanism 5 is started. The driving mechanism 5 drives the valve stem 7 to rotate, and the valve stem 7 drives the valve core 8 to rotate inside the ball valve body 1, thereby adjusting the flow size of the through hole of the valve core 8 and controlling the flow rate. When calculating the flow rate, the pressure sensor 10 detects the pressure of the fluid inside the ball valve body 1 and transmits the detection result to the master control center. The master control center calculates the flow rate value through the pressure value and transmits the flow rate value to the indicating disk 6. The pointer of the indicating disk 6 rotates to display the flow rate value, facilitating the user to directly obtain the fluid usage value inside the ball valve body 1.
