Abstract
Description
Technical Field
[0001] This utility model relates to the field of filling stop valve technology, specifically a filling stop valve for viscous liquids. Background Technology
[0002] A valve is a component used to control the flow of materials in pipelines. It is widely used in pipelines for conveying liquid, powder, and granular media. Depending on the application, valves can be divided into several types, such as shut-off valves, check valves, and regulating valves. In material feeding and filling, shut-off valves are often used to control the flow of materials.
[0003] Existing valves can stop the flow of liquids and gases in pipelines. However, they are more difficult to stop the flow of viscous liquids than liquids or gases. This is because viscosity can easily cause leakage through sealing gaps, leading to leakage and flow problems. Therefore, traditional check valves have limitations in use. In addition, vibrations during equipment operation can affect the valve's rotation, causing it to open on its own and affecting the flow-stopping effect. Utility Model Content
[0004] The purpose of this utility model is to provide a viscous liquid filling check valve. By continuously rotating the valve stem, the valve core is inserted into the inside of the flow pipe. At the same time, the valve core abuts against the movable semicircle, moves it, and fits it with the fixed semicircle. The valve core is engaged by the mating groove between the semicircle and the fixed semicircle.
[0005] To achieve the above objectives, a viscous liquid filling check valve is provided, comprising: a check valve body, a flow channel fixedly connected to the center of the valve body, a fixed semicircle fixedly connected to one end of the flow channel, a movable semicircle provided on one side of the fixed semicircle, a mating groove provided between the fixed semicircle and the movable semicircle, a valve core inserted into the flow channel, and a sealing ring fixedly connected to the outside of the valve core;
[0006] A valve stem is fixedly connected to the middle of one end of the valve core, and a handwheel is fixedly connected to one end of the valve stem. A limit rod is inserted into one side of the inside of the handwheel.
[0007] According to the aforementioned viscous liquid filling check valve, a fixed sleeve is fixedly connected to one side of the middle part of the check valve body, and a support spring is fixedly connected inside the fixed sleeve, with one end of the support spring fixedly connected to a limiting rod.
[0008] According to the aforementioned viscous liquid filling check valve, a feed pipe is fixedly connected to the top end of the check valve body, and a discharge pipe is fixedly connected to the bottom end of the check valve body.
[0009] According to the aforementioned viscous liquid filling check valve, a groove is provided on one side of the flow pipe, and a slider is slidably fitted inside the groove, and the slider and the movable semicircle are fixedly connected.
[0010] According to the aforementioned viscous liquid filling check valve, the valve core is conical, and the diameters of the two upper sealing rings are larger than the diameter of the lower sealing ring.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model is provided with a valve stem, a valve core, a flow channel, a fixed semicircle, and a movable semicircle. By continuously rotating the valve stem, the valve core is inserted into the flow channel. At the same time, the valve core abuts against the movable semicircle, moving it to fit against the fixed semicircle. The mating groove between the semicircle and the fixed semicircle enhances the barrier effect and increases the multi-layer flow-stopping effect to prevent liquid seepage and flow.

[0023] Please see Figure 1-4This utility model provides a technical solution: a viscous liquid filling check valve, comprising: a check valve body 1, with a flow channel 7 fixedly connected inside the check valve body 1. A valve core 8 abuts against the flow channel 7, achieving a sealing fit and blocking the flow of liquid through the flow channel 7. Simultaneously, the valve core 8 can be inserted into the flow channel 7 through continuous rotation of the valve stem 5, achieving a sealing and flow-stopping effect. A fixed semicircle 10 is fixedly connected to one end of the flow channel 7. The fixed semicircle 10 fits snugly, and the mating groove 13 between the semicircle 11 and the fixed semicircle 10 increases its blocking effect, providing multiple layers of flow-stopping effect to prevent liquid seepage. A movable semicircle 11 is provided on one side of the fixed semicircle 10. A mating groove 13 is provided between the fixed semicircle 10 and the movable semicircle 11. The mating groove 13 structure can be used to fit the fixed semicircle 10 and the movable semicircle 11 to achieve a complete sealed circular cover structure, which can block the flow of liquid. A valve core 8 is inserted into the inside of the flow pipe 7. A sealing ring 9 is fixedly connected to the outside of the valve core 8. The sealing ring 9 structure can abut against the inner wall of the flow pipe 7 to achieve a sealing contact and prevent liquid from seeping through. A sliding groove is provided on one side of the flow pipe 7. A slider 12 is slidably fitted inside the sliding groove. The cooperation between the slider 12 and the sliding groove can improve the stability of the lifting and sliding. The slider 12 is fixedly connected to the movable semicircle 11. The valve core 8 is conical, and the diameter of the two upper sealing rings 9 is larger than the diameter of the lower sealing ring 9.
[0024] A valve stem 5 is fixedly connected to the middle of one end of the valve core 8. A handwheel 4 is fixedly connected to one end of the valve stem 5. By rotating the handwheel 4, the valve stem 5 and the stop valve body 1 are threaded together, which can realize the movement of the threaded position. The valve core 8 and the flow pipe 7 are in contact to achieve a sealing fit. A limit rod 15 is inserted into one side of the inside of the handwheel 4. A fixing sleeve 3 is fixedly connected to one side of the middle of the stop valve body 1. A support spring 14 is fixedly connected inside the fixing sleeve 3. After the stop valve body 1 is adjusted, the limit rod 15 can be inserted through the handwheel 4 by the elastic support of the support spring 14 inside the fixing sleeve 3 to achieve the locking effect, preventing the handwheel 4 from rotating due to vibration. One end of the support spring 14 is fixedly connected to the limit rod 15. A feed pipe 2 is fixedly connected to the top of the stop valve body 1. Both the feed pipe 2 and the discharge pipe 6 are connected to the flange of the stop valve body 1. A discharge pipe 6 is fixedly connected to the bottom of the stop valve body 1.
[0025] Working principle: In use, the feed pipe 2 and the discharge pipe 6 are first connected to the flange of the stop valve body 1. After connection, the handwheel 4 is rotated, and the valve stem 5 is threaded into the stop valve body 1, which moves the threaded position. The valve core 8 abuts against the flow pipe 7, which provides a sealing fit and blocks the flow of liquid in the flow pipe 7. At the same time, the valve stem 5 is continuously rotated, and the valve core 8 is inserted into the flow pipe 7. The valve core 8 abuts against the movable semicircle 11, moves it, and fits against the fixed semicircle 10. The mating groove 13 between the semicircle 11 and the fixed semicircle 10 increases the barrier effect and adds multiple layers of flow control to prevent liquid seepage. After adjustment, the stop valve body 1 is locked by the elastic support of the internal support spring 14 of the fixed sleeve 3, which allows the limit rod 15 to pass through the handwheel 4, thus preventing the handwheel 4 from rotating due to vibration.
