[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] The pneumatic enamel discharge valve disclosed in this utility model is mainly used in scenarios where the bellows sleeve of the pneumatic enamel discharge valve is prone to damage after long-term use and its airtightness cannot be monitored in real time, leading to solution leakage and corrosion of the equipment, thereby reducing production efficiency and increasing maintenance costs.

[0021] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 A pneumatic enamel discharge valve includes a valve body support 4; a valve stem guide 3, which is positioned above the valve body support 4, with its bottom port connected to the top port of the valve body support 4 via a flange; a valve body 2, which is positioned above the valve stem guide 3, with its top port connected to the bottom port of the feed pipe 1 via a flange; and an airtightness monitoring component 11, located on the outer wall of the valve stem guide 3. The airtightness monitoring component 11 includes an air supply pipe 1101, and a fixing seat 1102 is fixedly connected to the outer wall of the valve stem guide 3, with one side of the fixing seat 1102 fixed. A pressure chamber 1104 is connected, and a pressure measuring chamber 1103 is fixedly connected to one side of the pressure chamber 1104. An air bladder 1113 is installed inside the pressure chamber 1104. One end of the air supply pipe 1101 passes through the fixing seat 1102 and is fixedly connected to the air bladder 1113 inside the pressure chamber 1104. One side of the pressure chamber 1104 is fixedly connected to one side of the fixing seat 1102. The other end of the air supply pipe 1101 is fixedly connected to the inside of the bellows sleeve 10. The bellows sleeve 10 is located inside the valve stem guide 3. Telescopic springs 1105 are fixedly connected at equal intervals to one side of the inside of the pressure chamber 1104.

[0022] Reference Figure 4 and Figure 5In a preferred embodiment, two telescopic springs 1105 are positioned above the airbag 1113. A T-shaped pressure plate 1106 is fixedly connected to one side of each of the two telescopic springs 1105. The bottom side of the T-shaped pressure plate 1106 abuts against the top side of the airbag 1113. A common displacement hole is provided on one side of the pressure chamber 1104 and the pressure measuring chamber 1103. The protruding end of the T-shaped pressure plate 1106 is slidably connected in the displacement hole. A pressure monitor 1110 is fixedly connected to one side of the inside of the pressure measuring chamber 1103, and a pressure monitor 1110 is fixedly connected to one side of the outer wall of the pressure measuring chamber 1103. Alarm 1109 is connected to pressure monitor 1110 via a data cable. T-shaped pressure plate 1106 is located inside pressure chamber 1103 and is fixedly connected to one side of connecting rod 1107. One end of connecting rod 1107 is fixedly connected to pressure hammer 1108, which is located above pressure monitor 1110. Air pump 1111 is fixedly connected to one side of pressure chamber 1104. Air pump 1111 is fixedly connected to air supply port of air pump 1111 and inflation pipe 1112. Air outlet of inflation pipe 1112 is fixedly connected to the inside of airbag 1113.

[0023] When the pneumatic enamel discharge valve is working, the gas in the air bladder 1113 is drawn into the bellows sleeve 10 through the air supply pipe 1101. The T-shaped pressure plate 1106, which abuts against the top of the air bladder 1113, continuously presses the air bladder 1113 downwards under the action of the extension spring 1105. Simultaneously, the connecting rod 1107, fixed at one end of the T-shaped pressure plate 1106 in the pressure measuring chamber 1103, moves downwards with the T-shaped pressure plate 1106. The pressure hammer 1108, fixed to one end of the connecting rod 1107, continuously applies pressure to the pressure sensing element on the pressure monitor 1110 in the pressure measuring chamber 1103. Under this structure, if the bellows sleeve 10 is damaged during the operation of the pneumatic enamel discharge valve, air leakage will cause the T-shaped pressure plate 1106 to... 106 further compresses the airbag 1113, thereby increasing the pressure on the pressure monitor 1110 by the pressure hammer 1108 and exceeding the threshold. At this time, the alarm 1109, which is fixedly connected to the outside of the pressure measuring chamber 1103, will trigger an alarm. Meanwhile, the air pump 1111 located outside the pressure chamber 1104 continuously inflates the airbag 1113 and even the inside of the corrugated sleeve 10 through the inflation pipe 1112. This device not only detects the airtightness of the corrugated sleeve 10 in real time when the pneumatic enamel discharge valve is working, but also continuously inflates the airbag 1113 and even the inside of the corrugated sleeve 10 through the inflation pipe 1112 when air leakage occurs, preventing the solution from entering the equipment during discharge and damaging the equipment, thus reducing work efficiency.

[0024] Reference Figure 1 , Figure 3 , Figure 6 and Figure 7In a preferred embodiment, a clamping support assembly 12 is provided on the outer wall of the valve body bracket 4, and the clamping support assembly 12 includes a support sleeve 1204. Sliding holes are opened opposite each other inside the valve body bracket 4, and support rods 1202 are slidably connected within the sliding holes. Both support rods 1202 are located inside the valve body bracket 4. One end of each support rod 1202 is fixedly connected to the same support sleeve 1204, and one end of each support rod 1202 is fixedly connected to a clamping block 1201. One side of the clamping block 1201 abuts against the outer wall of the valve body bracket 4. Sliding tracks are opened on opposite sides of the clamping block 1201, and the same belt 1203 is slidably connected within each sliding track. One end of the belt 1203 is fixedly connected to one of the clamping blocks 1201. 1. One end of the belt 1203 is fixedly connected to a toothed lock head 1205, which is located inside one of the clamping blocks 1201. A rotating hole is opened inside the clamping block 1201, and a rotating shaft 1209 is slidably connected inside the rotating hole. A driven gear 1210 is fixedly connected to the outer wall of the rotating shaft 1209. The driven gear 1210 meshes with the tooth groove of the toothed lock head 1205. One end of the rotating shaft 1209 is slidably connected to a connecting rod 1208 through a sliding shaft. A rotating handle 1206 is fixedly connected to one end of the connecting rod 1208. A limit plate 1207 is fixedly connected to the outer side of one of the clamping blocks 1201, and the outer wall of the connecting rod 1208 abuts against the groove of the limit plate 1207.

[0025] Before the pneumatic enamel discharge valve operates, the driven gear 1210 fixedly connected to the outer wall of the rotating shaft 1209 is rotated by rotating the rotary handle 1206. The toothed locking head 1205, which meshes with the driven gear 1210, moves inward under the action of the driven gear 1210, causing the belt 1203 fixedly connected to the toothed locking head 1205 to tighten continuously. During this process, the clamping device can quickly switch the clamping height as the valve stem 8 rises and falls. The limiting plate 1207 prevents the rotary handle 1206 from rebounding when locking. The support rod 1202, which is slidably connected to the clamping block 1201, and the support sleeve (1204) fixedly connected to the outer side of the valve stem 8 are also connected. With this structure, the valve stem 8 is fully clamped while avoiding damage to the pneumatic control device 5 fixedly connected to the bottom.

[0026] Reference Figure 1 and Figure 2In a preferred embodiment, the bottom port of the valve body bracket 4 is connected to the pneumatic control device 5 via a flange. The power output shaft of the pneumatic control device 5 is fixedly connected to the bottom of the valve stem 8. The valve stem 8 is located on the outer side of the valve body bracket 4 and is fixedly connected to the support sleeve 1204. One end of the valve stem 8 is fixedly connected to an integral valve core 6. The integral valve core 6 and the valve stem 8 are tightened by threads. A sealing gland 9 is fixedly connected inside the valve stem guide 3. The bottom of the sealing gland 9 is connected to the top port of the valve body bracket 4 and the bottom port of the valve stem guide 3 via a flange. A valve seat 7 is fixedly connected to the inner wall of the valve body 2 near the port.

[0027] Working principle: When the pneumatic enamel discharge valve is working, rotating the rotary handle 1206 loosens the belt 1203. Then, the valve stem 8 is raised to the required height via the pneumatic control device 5. Rotating the rotary handle 1206 again tightens the belt 1203, so that the clamping support assembly 12 is at the same height as the valve stem 8 and continuously clamps the valve stem 8. At the same time, as the valve stem 8 rises, the integrated valve core 6 leaves the valve seat 7, and the solution enters the valve body 2 from the feed pipe 1, and then passes through the valve body. The material is conveyed out of the outlet of 2. During this process, as the valve stem 8 rises, the corrugated sleeve 10, which is fixedly connected to the outer wall of the valve stem 8, extends accordingly. As the gas in the airbag 1113 is drawn into the corrugated sleeve 10 through the air supply pipe 1101, the T-shaped pressure plate 1106, which abuts against the top of the airbag 1113, continuously squeezes the airbag 1113 downward under the action of the telescopic spring 1105. At the same time, the connecting rod 110, which is fixed at one end of the T-shaped pressure plate 1106 in the pressure measuring chamber 1103, is also involved. 7. As the T-shaped pressure plate 1106 moves downward, the pressure hammer 1108, which is fixedly connected to one end of the connecting rod 1107, continuously applies pressure to the pressure sensing element on the pressure monitor 1110 inside the pressure measuring chamber 1103. The pressure monitor 1110 records the pressure at this time as a threshold. When the valve rod 8 is adjusted, it will be recorded again. If the valve rod 8 is not adjusted during operation and the threshold is exceeded, the bellows sleeve 10 may be damaged. Due to air leakage, the T-shaped pressure plate 1106 further compresses the air bladder 1113, thereby increasing the pressure of the pressure hammer 1108 on the pressure monitor 1110 and exceeding the threshold. At this time, the alarm 1109, which is fixedly connected to the outside of the pressure measuring chamber 1103, will trigger an alarm. Meanwhile, the air pump 1111, located outside the pressure chamber 1104, continuously inflates the air bladder 1113 and even the inside of the bellows sleeve 10 through the air inflator 1112 to prevent the solution from entering the equipment during material discharge and damaging the equipment, so as to ensure that the machine can continue to work temporarily.

[0028] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
