Description

Technical Field

[0001] This utility model belongs to the field of bottom valve technology, and relates to a bottom valve with a temperature measuring inclined rod. Background Technology

[0002] Bottom valves are specialized valves installed at the bottom of containers such as reactors and storage tanks, primarily used for discharging materials or media.

[0003] Traditional reactors typically have temperature monitoring at the top or middle. However, without temperature monitoring during the discharge process via the bottom valve, excessively low or high temperatures can lead to low-temperature crystallization and blockage, or unreacted monomers polymerizing and exploding due to high temperatures. To address these issues, we designed a bottom valve with a temperature-sensing slant rod. This ensures that every portion of the discharged material reaches the expected reaction endpoint, guaranteeing product quality. For some polymerization reactions, temperature monitoring at the bottom valve allows for more precise temperature control and ensures safe termination of the reaction. Summary of the Invention

[0004] The purpose of this invention is to provide a bottom valve with a temperature measuring rod to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solution: a bottom valve with a temperature measuring slant rod, including a bottom valve body with a slant rod, an actuator for controlling the opening and closing of the bottom valve body is provided on one side of the bottom valve body with a temperature measuring sleeve that is integrally connected to it, and a thermometer is fixedly installed inside the temperature measuring sleeve.

[0006] In the above-mentioned bottom valve with temperature measuring slant rod, the actuation component includes a gearbox and a valve body actuator. The gearbox is fixedly installed on the other side of the bottom valve body, and the valve body actuator is fixedly connected to the input end of the gearbox.

[0007] In the above-mentioned inclined rod bottom valve with temperature measurement, a drive shaft is rotatably connected inside the inclined rod bottom valve body. One end of the drive shaft is fixedly connected to the valve plate inside the inclined rod bottom valve body, and the other end of the drive shaft extends to the outside and is fixedly connected to the output end of the gearbox through a coupling.

[0008] In the aforementioned bottom valve with temperature measuring rod, one end of the valve body actuator is fixedly connected to a feedback device, and a solenoid valve is fixedly installed in the side pipeline of the valve body actuator.

[0009] In the aforementioned bottom valve with temperature measuring rod, the temperature detection range of the thermometer is -28℃ to 160℃.

[0010] In the above-mentioned bottom valve with temperature measuring slant rod, the top and bottom of the valve body are both fixedly provided with an integral mounting flange.

[0011] Compared with the prior art, the advantages of this utility model with temperature-measuring inclined rod bottom valve are: by setting a temperature-measuring sleeve on the side wall of the inclined rod bottom valve and setting a thermometer inside the temperature-measuring sleeve, it is possible to achieve online and precise control of the bottom temperature of the reactor, avoiding the crystallization and blockage of the bottom material caused by low temperature or the polymerization and explosion of unreacted monomers due to temperature runaway.

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figure 1 As shown, the present invention includes a bottom valve with a temperature measuring rod, comprising a bottom valve body 1, an actuator for controlling the opening and closing of the bottom valve body 1 is provided on one side of the bottom valve body 1, and a temperature measuring sleeve 7 integrally connected to one side of the bottom valve body 1, wherein a thermometer 8 is fixedly installed inside the temperature measuring sleeve 7.

[0016] Specifically, by installing a temperature measuring sleeve 7 on the side wall of the inclined rod bottom valve and a thermometer 8 inside the temperature measuring sleeve 7, the temperature of the inclined rod bottom valve body 1 can be monitored in real time. This can prevent the inclined rod bottom valve body 1 from being damaged by excessively high or low temperatures when passing through it.

[0017] like Figure 1 As shown, the present invention relates to a bottom valve with a temperature measuring slant rod. The actuation components include a gearbox 5 and a valve body actuator 2. The gearbox 5 is fixedly installed on the other side of the slant rod bottom valve body 1, and the valve body actuator 2 is fixedly connected to the input end of the gearbox 5.

[0018] The inclined rod bottom valve body 1 is internally connected to a drive shaft 6. One end of the drive shaft 6 is fixedly connected to the valve plate inside the inclined rod bottom valve body 1, and the other end of the drive shaft 6 extends to the outside and is fixedly connected to the output end of the gearbox 5 through a coupling.

[0019] Specifically, the transmission shaft 6 is used to connect the gearbox 5 with the valve plate inside the inclined rod bottom valve body 1.

[0020] A feedback device 3 is fixedly connected to one end of the valve body actuator 2, and a solenoid valve 4 is fixedly installed in the side pipeline of the valve body actuator 2.

[0021] The temperature detection range of thermometer 8 is -28℃ to 160℃. Specifically, the improved temperature detection range of thermometer 8 enhances its adaptability.

[0022] The top and bottom of the inclined rod bottom valve body 1 are both fixed with integral mounting flanges. Specifically, the mounting flanges facilitate the installation of the inclined rod bottom valve body 1 with the material discharge section.

[0023] In specific implementation, when using the inclined rod bottom valve with temperature measurement, first install the inclined rod bottom valve at the discharge position and connect the power supply. When discharge is required, the valve body actuator 2 and gearbox 5 work together to drive the rotation of the transmission shaft 6. The transmission shaft 6 drives the valve plate inside the inclined rod bottom valve body 1 to rotate, thereby opening the inclined rod bottom valve body 1 to discharge the material. During the discharge process, the temperature of the inclined rod bottom valve body 1 is detected in real time by the thermometer 8 inside the temperature measuring sleeve 7.
