Description

Technical Field

[0001] This utility model belongs to the field of reaction vessel technology and relates to a manual pneumatic bottom valve with temperature measurement. Background Technology

[0002] In the chemical industry, reaction vessels are important tools for chemical reaction experiments. Among them, the bottom valve is an important component of the reaction vessel, which is installed at the outlet of the reaction vessel to control the release of materials.

[0003] Traditional reactors typically have temperature monitoring at the top or middle. Since there's no temperature monitoring mechanism during material discharge from the bottom valve, excessively low or high temperatures can lead to low-temperature crystallization and blockage, or unreacted monomers polymerizing and exploding at high temperatures. Furthermore, when blockage occurs at the reactor's outlet, the traditional method involves opening a tee on the process pipeline below the bottom valve and adding nitrogen to clear the blockage – a cumbersome process. Summary of the Invention

[0004] The purpose of this invention is to provide a manual pneumatic bottom valve with temperature measurement 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 manual pneumatic bottom-mounted valve with temperature measurement, comprising a valve body, a valve seat detachably and fixedly installed at the top of the valve body, a valve core installed at the top of the valve seat, a temperature measuring sleeve inserted inside the valve body, one end of the temperature measuring sleeve being fixedly connected to the valve core, and a temperature sensor being fixedly installed at the connection between the temperature measuring sleeve and the valve core, and a thermometer being fixedly installed at the other end of the temperature measuring sleeve extending to the outside, the thermometer being electrically connected to the temperature sensor.

[0006] In the above-mentioned manual pneumatic bottom valve with temperature measurement, a nitrogen purging pipe is fixedly provided on the side of the valve body, and a control valve is fixedly connected to the flange of the nitrogen purging pipe.

[0007] In the above-mentioned manual pneumatic valve with temperature measurement at the bottom of the reactor, a sealing packing is fixedly provided at the insertion connection between the temperature measuring sleeve and the valve body, and the sealing packing is made of graphite.

[0008] In the above-mentioned manual pneumatic bottom valve with temperature measurement, an integral mounting flange is fixed at the outlet of the valve body, and the surface of the mounting flange is provided with uniformly distributed assembly holes.

[0009] In the above-mentioned manual pneumatic valve with temperature measurement at the bottom of the reactor, a sealing ring is fitted at the connection between the valve body and the valve seat, and the valve seat is convex in shape.

[0010] In the above-mentioned manual pneumatic bottom valve with temperature measurement, a support frame is fixedly connected to the bottom of the valve body, and a valve body actuator is fixedly installed at the bottom of the support frame. A rotating handwheel is fixedly installed at the drive end of the valve body actuator. The valve body actuator adopts one of the SCL series or SC series.

[0011] Compared with existing technologies, the advantages of this utility model with a manual pneumatic temperature-measuring valve at the bottom of the reactor are: 1. By inserting a temperature measuring sleeve inside the valve body and setting a temperature sensor at one end of the sleeve and a thermometer at the other end, the temperature at the outlet of the valve on the bottom of the vessel can be monitored in real time. This can prevent the reaction material from crystallizing and clogging due to excessively high or low temperatures, or prevent unreacted monomers from polymerizing and exploding due to high temperatures.

[0012] 2. The valve body is equipped with a control valve connected to the nitrogen purge pipe flange on the side. In case of material blockage, it can be used as a nitrogen purge valve, which replaces the traditional method of opening a tee at the bottom of the valve and adding nitrogen to clear the blockage, thus improving the practicality of the valve body.

[0015] 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.

[0016] like Figure 1 As shown, the present invention relates to a manual pneumatic bottom-mounted valve with temperature measurement, comprising a valve body 1, a valve seat 2 detachably and fixedly installed at the top of the valve body 1, a valve core 3 installed at the top of the valve seat 2, a temperature measuring sleeve 9 inserted inside the valve body 1, one end of the temperature measuring sleeve 9 being fixedly connected to the valve core 3, and a temperature sensor 4 being fixedly installed at the connection between the temperature measuring sleeve 9 and the valve core 3, and a thermometer 8 being fixedly installed at the other end of the temperature measuring sleeve 9 extending to the outside, and the thermometer 8 being electrically connected to the temperature sensor 4.

[0017] Specifically, by inserting a temperature measuring sleeve 9 inside the valve body 1, and setting a temperature sensor 4 at one end of the temperature measuring sleeve 9 and a thermometer 8 at the other end of the temperature measuring sleeve 9, the temperature at the outlet of the valve on the bottom of the vessel can be monitored in real time. This can prevent the reaction material from crystallizing and blocking due to excessively high or low temperatures, or prevent unreacted monomers from polymerizing and exploding due to high temperatures.

[0018] It should be noted that the model number of this temperature sensor 4 is "WZPB-441S".

[0019] like Figure 1 As shown, the present invention has a temperature-measuring manual pneumatic bottom valve for a reactor. A nitrogen purge pipe 13 is fixedly provided on the side of the valve body 1, and a control valve is fixedly connected to the flange of the nitrogen purge pipe 13.

[0020] Specifically, the nitrogen purge pipe 13 enables nitrogen backflushing, which can handle material blockage.

[0021] A sealing packing 7 is fixed at the insertion connection between the temperature measuring sleeve 9 and the valve body 1. The sealing packing 7 is made of graphite.

[0022] Specifically, the sealing of the temperature measuring sleeve 9 and the valve body 1 is improved by setting the sealing packing 7.

[0023] A mounting flange 6, which is integrally connected, is fixedly provided at the outlet of the valve body 1. The surface of the mounting flange 6 is provided with evenly distributed assembly holes.

[0024] Specifically, the installation of flange 6 facilitates the connection between valve body 1 and pipeline.

[0025] A sealing ring 5 is fitted at the connection between the valve body 1 and the valve seat 2, and the valve seat 2 is convex in shape.

[0026] Specifically, the sealing ring 5 improves the sealing performance between the valve body 1 and the valve seat 2. The valve seat 2 has a convex shape design, which not only eliminates material bridging and blockage at the bottom outlet of the reactor, but also ensures more accurate temperature measurement at the temperature measuring point.

[0027] A support frame 10 is fixedly connected to the bottom of the valve body 1. A valve body actuator 11 is fixedly installed at the bottom of the support frame 10. A rotary handwheel 12 is fixedly installed at the drive end of the valve body actuator 11. The valve body actuator 11 adopts either the SCL series or the SC series.

[0028] Specifically, the opening and closing of the valve body 1 is controlled by rotating the handwheel 12 and the valve body actuator 11.

[0029] In specific implementation, when using the manual pneumatic bottom-mounted valve with temperature measurement, first install the valve at the discharge port of the reactor and connect the power supply. When discharge is required, manually rotate the handwheel 12 and the valve body actuator 11 to open the pneumatic bottom-mounted valve. When the material passes through the valve core 3, the temperature is detected in real time by the temperature sensor 4 and displayed in real time by the thermometer 8. When material blockage occurs inside the valve body 1, nitrogen can be connected to the nitrogen pipeline through the nitrogen purging pipe 13 to purge the blockage. This replaces the traditional method of opening a tee and adding nitrogen to the process pipeline at the lower end of the bottom-mounted valve for backflow clearing, thus improving the practicality of the valve body.
