Description

Technical Field

[0001] The present application relates to the technical field of temperature control valves, and in particular to a novel valve body separation alarm structure. Background Art

[0002] The temperature control valve mainly consists of a valve body, an actuator, a remote transmission device, a control platform, etc. The actuator information is obtained through the remote transmission device, and the status of the valve body is obtained by the control platform. The separation and connection status of the valve body and the actuator can be effectively detected, and the control platform can be controlled through signal transmission so that the staff can respond in time.

[0003] However, in actual applications, there are cases where the temperature control valve is damaged. Some of the reasons are caused by human damage. For example, if the valve body is opened for heating without permission, the valve body may be separated from the actuator after being damaged by personnel. The valve body is not controlled by the actuator, which makes it impossible for staff to remotely monitor through the control platform. This will not only cause losses to the heating unit and affect the normal heating of users, but also if other accidents occur, such as uncontrolled and disordered heating, bigger problems may occur.

A valve stem with a built-in blind hole is installed in the valve body, the top of the shell is connected to the bottom of the actuator power output shaft, a magnet is arranged on the valve stem, and the shell is arranged in the built-in blind hole of the valve stem.

[0007] By adopting the above technical solution and setting the magnetic sensor, when the sensor is close to the magnet, the internal state of the sensor changes, and the signal is transmitted to the PCB board through the core wire to realize signal collection, and the detection is realized by the host computer, and then the actuator is detected to be connected to the valve body. Similarly, when the actuator is taken out, the shell and the sensor inside the shell are pulled out, the sensor is away from the magnet, the internal state of the sensor changes, and it is retrieved that the actuator and the valve body are separated. In summary, the detection of whether the actuator is connected to the valve body is realized.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The following is combined with Figures 1 to 4 This application is described in further detail.

[0028] The embodiment of the present application discloses a novel valve body separation alarm structure.

[0029] Reference Figures 1 to 4 A new valve body separation alarm structure, a valve body 1 and an actuator installed on the valve body 1, also includes a shell 2, the shell 2 is a steel shell with a top opening, a magnetic sensor 3 and a temperature sensor 4 are welded to the bottom end of a core wire 5 and built into the shell 2, a magnetic sensor 3, and a magnetic sensor 3 is located at the bottom end of the shell 2.

[0030] A through hole is provided at the center of the actuator power output shaft 6, the top of the shell 2 is connected to the bottom of the actuator power output shaft 6, the core wire 5 passes through the shell 2, passes through the bottom of the actuator power output shaft 6 and is welded to the PCB board of the actuator. The layout of the core wire 5 is concealed and reasonable, and the structure is simple.

[0031] A valve stem 7 with a built-in blind hole is installed in the valve body 1, and a magnet 8 is arranged on the valve stem 7. Magnets 8 are arranged at the bottom end of the blind hole of the valve stem 7 and the bottom end of the valve stem 7 to ensure the magnetic field strength and ensure that the magnetic sensor 3 can operate normally. The housing 2 is inserted into the blind hole from the top end of the valve stem 7.

[0032] The bottom of the actuator power output shaft 6 is inserted into the top of the valve stem 7, and a seal is set between the core wire 5 and the through hole of the actuator power output shaft 6. A sealing ring groove A is opened at the bottom of the through hole of the actuator power output shaft 6, and a sealing ring A9 is arranged in the sealing ring groove A. A sealing ring groove B is opened on the valve stem 7, and a sealing ring B10 is arranged in the sealing ring groove B, which is sealed with the valve body 1.

[0033] Through the setting of the magnetic sensor 3, when the magnetic sensor 3 is close to the magnet, the internal state of the sensor changes, and the signal is transmitted to the PCB board through the core wire 5 to realize signal collection, and the detection is realized by the host computer, and then the actuator is detected to be connected to the valve body 1. Similarly, when the actuator is taken out, the shell 2 and the sensor in the shell 2 are pulled out, the sensor is away from the magnet 8, the internal state of the sensor changes, and it is detected that the actuator and the valve body 1 are separated. In summary, the detection of whether the actuator is connected to the valve body 1 is realized.

[0034] Specific implementation process:

[0035] The magnetic sensor 3 and the temperature sensor 4 are welded to the multi-core wire 5 and built into the steel shell. Then the core wire 5 is passed through the bottom of the power output shaft 6 and welded to the PCB board inside the actuator, and the top of the power output shaft 6 is clamped. When threading, the sealing ring A9 is placed in the bottom hole of the actuator power output shaft 6 in advance.

[0036] A valve stem 7 with a built-in blind hole is installed at the center of the upper end of the valve body 1. A pair of strong magnets 8 are pre-installed at the bottom of the valve stem 7. When the actuator is installed as a whole on the valve body 1, the housing 2 with a built-in magnetic sensor 3 and a temperature sensor 4 is inserted into the built-in blind hole of the valve stem 7. When the magnetic sensor 3 is close to the magnet 8, the internal state of the magnetic sensor 3 changes, the PCB detects a closing signal and transmits the signal to the upper computer (control platform), indicating that the valve body 1 is successfully connected to the actuator.

[0037] When the actuator is removed, the housing 2 with the built-in magnetic sensor 3 and the temperature sensor 4 is pulled out from the built-in blind hole of the valve stem 7 and away from the magnet 8 at the bottom of the valve stem 7. The internal state of the magnetic sensor 3 changes, and the PCB detects the signal and transmits the signal to the host computer (control platform), indicating that the valve body 1 is disconnected from the actuator.
