Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a pushcart valve. Background Technology

[0002] In existing technologies, materials are transported through shell-type pipelines, which frequently require cleaning. During the actual cleaning process, it is difficult to avoid the materials becoming wetted by the cleaning water, thus affecting their quality. Therefore, a trolley valve needs to be designed to facilitate cleaning of the shell-type pipelines without affecting the materials. Utility Model Content

[0003] To address the aforementioned technical shortcomings, this invention provides a trolley valve that enables online cleaning of the housing and pipes without affecting the materials.

[0004] This utility model discloses a trolley valve, including a valve body. The valve body has a rectangular cylindrical structure. The side walls at both ends of the valve body extend outward to form connecting flanges, and a number of connecting holes are arranged at intervals on the connecting flanges. A water receiving groove extends outward on one side wall of the valve body, and a drain pipe is provided on one side wall of the water receiving groove. A rectangular elongated hole is provided on the side wall of the valve body within the water receiving groove range. The length of the rectangular elongated hole is consistent with the corresponding hollow length inside the valve body. Slide rails are provided on the side walls of the valve body on both sides of the rectangular elongated hole, and valve buckets are provided on the slide rails. A number of drain holes are arranged at intervals on the side wall of the valve bucket near the water receiving groove. When the valve bucket moves into the valve body, it is used to seal the valve body. When the valve bucket moves to the outside of the valve body, it is used to seal the rectangular elongated hole.

[0005] The slide rail extends into the water receiving tank. Two rollers are provided at both ends of the valve bucket. The rollers are fitted onto the slide rail. An inclined baffle is provided above the slide rail inside the valve body. The baffle covers the rollers, and the lower edge of the baffle is in contact with the side wall of the valve bucket.

[0006] The bottom wall of the valve bucket is inclined, with the lowest position of the bottom wall of the valve bucket near the water receiving tank. The drain hole is located at the lowest position above the bottom wall of the valve bucket.

[0007] A handle is installed on the side wall of the valve hopper near the water receiving tank.

[0008] The bottom wall of the water receiving tank has a V-shaped structure, and the drain pipe is installed on the side wall of the drain tank corresponding to the lowest point of the bottom wall.

[0009] The trolley valve obtained by this utility model can block a rectangular elongated hole on one side when the valve bucket is pulled out into the water receiving tank, thereby forming a material conveying channel inside the valve body and cooperating with the upper and lower pipes for material conveying. When it is necessary to clean the upper pipe, simply push the valve bucket into the valve body. At this time, the valve bucket blocks the valve body, and the cleaning water of the upper pipe enters the valve bucket and enters the drainage tank through the drain hole to clean the pipe without affecting the material below. It is safe, reliable and easy to operate. Attached Figure Description

Detailed Implementation

[0011] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0012] Example 1: like Figures 1-8As shown, this utility model discloses a trolley valve, including a valve body 1. The valve body 1 has a rectangular cylindrical structure. Connecting flanges 2 are formed by extending outward from the upper and lower side walls of the valve body 1. Several connecting holes 3 are provided at intervals on the connecting flanges 2. A water receiving groove 7 is formed by extending outward from one side wall of the valve body 1. A drain pipe 8 is provided on one side wall of the water receiving groove 7. A rectangular elongated hole is provided on the side wall of the valve body 1 within the range of the water receiving groove 7. The length of the rectangular elongated hole is consistent with the corresponding hollow length inside the valve body 1. Slide rails 5 are provided on the side walls of the valve body 1 on both sides of the rectangular elongated hole. A valve bucket 4 is provided on the slide rails 5. Several drain holes 10 are provided at intervals on the side wall of the valve bucket 4 near the water receiving groove 7. When the valve bucket 4 moves into the valve body 1, it is used to block the valve body 1. When the valve bucket 4 moves to the outside of the valve body 1, it is used to block the rectangular elongated hole.

[0013] The dimensions of valve body 1 are matched to the dimensions of the pipe it connects to. Its upper and lower ends extend outwards to form connecting flanges 2, and are provided with connecting holes 3. These connecting holes 3 allow for a stable and secure connection with the pipe, ensuring the stability of material transport. A rectangular elongated hole is provided on one side of valve body 1, the length of which is sufficient to penetrate the side wall of valve body 1. A valve bucket 4 is disposed within this rectangular elongated hole. This valve bucket 4 is drawer-shaped. When valve bucket 4 is pulled out of the rectangular elongated hole until its end face aligns with the rectangular elongated hole, the end face of valve bucket 4 seals the rectangular elongated hole, thus allowing valve body 1 to be open and material in the pipe to pass through. After valve bucket 4 is inserted into the rectangular elongated hole into the valve body 1, its four side walls fit against the inner wall of valve body 1, thus sealing valve body 1. The sealing between the side walls of valve bucket 4 and the inner wall of valve body 1 can be achieved using sealing strips or similar conventional methods that should be known and achievable by those skilled in the art. With the valve body 1 closed by the valve hopper 4, the pipes above the valve body 1 can be cleaned. After flushing the pipes with water, the cleaning water falls into the valve hopper 4 and is discharged outward from the drain hole 10 on the side of the valve hopper 4 into the water receiving tank 7. The cleaning water is then discharged to a designated location through the drain pipe 8 on the side of the water receiving tank 7. The cross-sectional area of ​​the drain hole 10 needs to be large enough to ensure that the cleaning water can be discharged from the valve hopper 4 into the water receiving tank 7 in a timely manner.

[0014] The slide rail 5 extends into the water receiving tank 7. Two rollers 6 are provided at both ends of the valve bucket 4. The rollers 6 are fitted onto the slide rail 5. An inclined baffle 9 is provided above the slide rail 5 inside the valve body 1. The baffle 9 covers the rollers 6, and the lower edge of the baffle 9 is in contact with the side wall of the valve bucket 4.

[0015] Since both ends of the valve bucket 4 are fitted with slide rails 5, to ensure smoother movement of the slide rails 5, the slide rails 5 extend into the water receiving groove 7. That is, the slide rails 5 fill the interior of the valve body 1 and the water receiving groove 7. The valve bucket 4 is positioned on the slide rails 5 when inserted into the valve body 1 or withdrawn into the water receiving groove 7. Rollers 6 are also provided on both sides of the valve bucket 4. These rollers 6 are slidably connected to the slide rails 5, making the withdrawal process smoother and more stable. However, due to the rollers 6, after the valve bucket 4 is inserted into the valve body 1, the side walls of the valve bucket 4 with the rollers 6 at both ends cannot completely fit against the inner wall of the valve body 1, leaving a certain gap for the rollers 6 to exist. To prevent cleaning water from seeping through the gap and into the material below the valve hopper 4 during pipe cleaning, a baffle 9 is installed on the inner side wall of the valve body 1 above the slide rail 5. The baffle 9 is inclined, meaning that the upper end of the baffle 9 is in contact with the inner wall of the valve body 1, and the lower end of the baffle 9 is inclined inward to block the gap between the valve hopper 4 and the valve body 1. The lower end of the baffle 9 extends to the inner side of the valve hopper 4 and contacts and fits against the side wall of the valve hopper 4, which can effectively send all the cleaning water of the pipe into the valve hopper 4, ensuring stability and reliability during use.

[0016] In practical use, a baffle 9 can also be provided on the inner wall of the valve body 1 opposite the rectangular long hole. Similarly, the baffle 9 is also inclined and in contact with the side wall of the valve bucket 4.

[0017] The bottom wall of the valve hopper 4 is inclined, with the lowest point of the bottom wall near the water receiving tank 7. The drain hole 10 is located at the lowest point above the bottom wall of the valve hopper 4. The inclined bottom wall of the valve hopper 4 allows the cleaning water to flow towards the drain hole 10, thereby quickly draining it into the water receiving tank 7, ensuring stable drainage, and preventing water accumulation inside the valve hopper 4.

[0018] A handle 11 is provided on the side wall of the valve hopper 4 near the water receiving tank 7. The handle 11 on the side wall makes it easier for the valve hopper 4 to enter and exit the valve body 1, making operation simpler and more convenient.

[0019] The bottom wall of the water receiving tank 7 has a V-shaped structure, and the drain pipe 8 is set on the side wall of the drain tank corresponding to the lowest point of the bottom wall.

[0020] The design of the water receiving tank 7 described above allows the cleaning water in the water receiving tank 7 to be discharged out faster and more efficiently.
