Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a high-strength corrosion-resistant valve with a double-layer shell. Background Technology

[0002] A valve is a mechanical device used to control the flow of fluids (such as liquids, gases, slurries, etc.), and it has a wide range of applications in various industrial fields and daily life.

[0003] In existing technologies, most traditional valves have a single-layer shell structure, meaning the valve core is located inside the shell. However, this has significant drawbacks during use. For example, when fluid passes through a traditional valve, changes in valve opening alter the fluid velocity. At the valve's throttling point, the velocity increases significantly. According to Bernoulli's principle, this increase in velocity leads to a decrease in pressure, potentially creating a localized low-pressure zone and inducing cavitation. The bursting of cavitation bubbles generates high-frequency noise. The single-layer structure of traditional valves cannot filter this noise, resulting in noise pollution during use. Therefore, this invention proposes a double-layer shell high-strength corrosion-resistant valve to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a double-shell high-strength corrosion-resistant valve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A double-shell high-strength corrosion-resistant valve includes a valve body, an outer valve shell, and a valve core. Both ends of the outer valve shell are fixedly connected to and communicate with pipes. Protective outer shells that slidably fit onto both pipes are also fitted onto the valve shell. The opposite ends of the two protective outer shells are open. Sound-insulating cotton is fixedly connected to the inner wall of each protective outer shell. Fixing plates are fixedly fitted onto both pipes. A moving mechanism for moving the two protective outer shells is provided between the two fixing plates.

[0007] Preferably, the moving mechanism includes two moving plates that are slidably sleeved on the two pipes, and the two moving plates are fixedly connected to the ends of the two protective shells.

[0008] Preferably, a double-threaded rod is rotatably connected between the two fixed plates, and the double-threaded rod passes through the two movable plates and is threadedly connected to them.

[0009] Preferably, a motor is fixedly connected to the side wall of one of the fixing plates, and the end of the output shaft of the motor is fixedly connected to the end of a double-threaded rod.

[0010] Preferably, a flange is fixedly connected to the end of each of the two pipes away from the valve housing.

[0011] Preferably, both of the protective housings have notches at their upper ends, and the two notches correspond to each other and cooperate with the valve body.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By setting up a protective shell, which is placed outside the valve body, the sound insulation cotton inside the protective shell can effectively isolate the noise generated by the valve body during operation, which can greatly improve the quietness of the valve body. At the same time, it can protect the valve body from external collisions and dust contamination.

[0014] 2. By setting up a moving mechanism, when the valve body needs to be repaired, the output shaft of the drive motor can be rotated, which drives the double-headed threaded rod to rotate, which drives the two moving plates connected to it to move to both ends, and drives the protective shells on both sides to move to both ends to complete the separation, which facilitates quick repair of the valve body. After the repair is completed, the output shaft of the drive motor reverses, which drives the two moving plates to move to the middle, so that the two protective shells move to the middle and cover the valve shell to achieve the protection effect.

[0021] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] Reference Figure 1-5 A double-shell high-strength corrosion-resistant valve includes a valve body 3, a valve shell 4 on the outside of the valve body 3, a valve core inside the valve shell 4, pipes 11 fixedly connected to both ends of the valve shell 4, protective shells 5 that cooperate with the valve shell 4 slidably sleeved on both pipes 11, one end of the two protective shells 5 being open, sound insulation cotton 501 fixedly connected to the inner wall of the protective shell 5, fixing plates 2 fixedly sleeved on both pipes 11, and a valve core cavity that cooperates with the valve core is also provided inside the valve shell 4.

[0023] Specifically, a moving mechanism for moving the two protective shells 5 is provided between the two fixed plates 2. The moving mechanism includes two moving plates 9 that are respectively slidably sleeved on the two pipes 11. The two moving plates 9 are respectively fixedly connected to the ends of the two protective shells 5. A double-threaded rod 7 is rotatably connected between the two fixed plates 2. The double-threaded rod 7 passes through the two moving plates 9 and is threadedly connected to them. A motor 6 is fixedly connected to the side wall of one of the fixed plates 2. The end of the output shaft of the motor 6 is fixedly connected to the end of the double-threaded rod 7. The threads at both ends of the double-threaded rod 7 are arranged in opposite directions.

[0024] Specifically, flanges 1 are fixedly connected to the ends of the two pipes 11 away from the valve housing 4, and notches 10 are opened at the upper end of each protective housing 5. The two notches 10 correspond to each other and cooperate with the valve body 3. By setting flanges 1, the valve body 3 can be quickly connected to the liquid supply pipe.

[0025] In use, the protective shell 5 is placed outside the valve shell 4. The sound insulation cotton 501 inside the protective shell 5 can effectively isolate the noise generated by the valve body 3 during operation, which can greatly improve the quietness of the valve body 3. At the same time, it can protect the valve shell 4 from external collisions and dust pollution. When the valve body 3 needs to be repaired, the output shaft of the drive motor 6 can be rotated, which drives the double-headed threaded rod 7 to rotate, which drives the two moving plates 9 connected to it to move to both ends, and drives the protective shells 5 on both sides to move to both ends to complete the separation, which facilitates the quick repair of the valve body 3. After the repair is completed, the output shaft of the drive motor 6 reverses, which drives the two moving plates 9 to move to the middle, so that the two protective shells 5 move to the middle and cover the valve shell 4 to achieve the protection effect.
