Description

Technical Field

[0001] This utility model relates to the field of dual-seat valve monitoring technology, specifically a fault-prevention and early warning device for adjusting dual-seat valves. Background Technology

[0002] A double-seat valve, more commonly known as a double-seat regulating valve, is an actuator in an automated control system. It features a compact structure, light weight, sensitive operation, large capacity, precise flow characteristics, and easy assembly and disassembly. The double-seat regulating valve automatically controls its opening based on signals from the regulating component, thereby regulating the flow rate, pressure, and level of the medium. When the electrical or pneumatic signal increases, the actuator drives the valve core to move, changing the valve opening and thus altering the flow rate of the medium.

[0003] Occasionally, during operation, the medium may not flow properly or the pressure may be too high or too low, requiring monitoring by staff. This not only consumes the staff's time, but also sometimes the problem cannot be detected in time. Therefore, this utility model proposes a foolproof early warning device for the adjustment double-seat valve. Utility Model Content

[0004] The purpose of this utility model is to provide a fault-prevention and early warning device for a dual-seat valve, which has a protection mechanism and can monitor and warn of the medium flow rate, pressure and temperature, ensuring the normal operation of the dual-seat valve and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mis-detection warning device for a dual-seat valve, comprising a lower housing and a flow meter. A PLC controller and an alarm are provided on the rear end face of the lower housing, with the alarm located on one side of the PLC controller. An upper housing is installed on the upper end of the lower housing. Corresponding semi-circular openings are provided on both sides of the lower and upper housings. A transparent window is provided at the front end of the upper housing. The flow meter is installed inside the lower housing. A detection tube and a connecting tube are threadedly installed at the inlet and outlet of the flow meter, respectively. A temperature sensor and a pressure detection valve are installed on the detection tube. The detection head of the temperature sensor is located inside the detection tube. Connectors are provided at the ends of both the detection tube and the connecting tube, extending from the semi-circular openings out of the lower and upper housings.

[0006] When using the anti-foolproof early warning device for adjusting a double-seat valve according to this utility model...

[0007] During installation, the detection structure is first placed inside the lower housing, with the connector extending from the semi-circular opening. The telescopic rod is manually retracted to allow the two retaining rings to fit over the outside of the connector, thus securing the detection structure. The housing is then installed. During operation, the two connectors are connected to the regulating double-seat valve and the media delivery pipeline, respectively. The instruments on the detection structure can be observed through the transparent window. The pressure detection valve detects the fluid pressure in the pipeline, the temperature sensor detects the fluid temperature, and the flow meter detects the fluid flow rate. If the pressure, temperature, or flow rate fluctuates excessively, the alarm will sound, alerting personnel to promptly identify and inspect the regulating double-seat valve.

[0008] Preferably, the outer surface of the upper box is rotatably mounted with a buckle plate, and there are four buckle plates in total, which are arranged in an array about the upper box.

[0009] Preferably, the outer surface of the lower box is fitted with a series of clips, and the buckle plate is snapped and fixed onto the clips.

[0010] Preferably, the bottom inner wall of the lower box is fitted with symmetrically distributed sleeve rods, the ends of which extend out of the lower box.

[0011] Preferably, a telescopic rod is movably sleeved inside the sleeve, and a fixing ring is installed at the end of the telescopic rod, which is sleeved on the outside of the connector. The fixing ring sleeved on the outside of the connector can fix the detection structure.

[0012] Preferably, a threaded hole is provided at the end of the sleeve rod on its side, and a fixing bolt is threaded into the threaded hole. The end of the fixing bolt contacts the telescopic rod to fix it in place. The fixing bolt secures the telescopic rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By monitoring the medium of the dispensing double-seat valve through a flow meter, temperature sensor and pressure detection valve, the flow rate, pressure and temperature of the medium can be monitored and early warning can be given. If a problem occurs in the dispensing double-seat valve, the staff can find and check it in time, ensuring the normal operation of the dispensing double-seat valve. Its detection structure is set in the upper box and the lower box, which can protect it. Moreover, the upper box and the lower box are simple to install and can be easily disassembled, making it convenient to inspect and maintain the internal structure. Attached Figure Description
