Description

Technical Field

[0001] This utility model relates to the field of one-way valve technology, specifically an integrated one-way valve structure. Background Technology

[0002] Conventional horizontal pumps on the market require at least two check valves to operate, such as Figure 1 As shown, it basically adopts a bypass-type check valve structure. The material is fed through the lower check valve port, enters the working cylinder through the bypass pipe and the overflow tee, and is discharged from the working cylinder through the reciprocating motion of the piston head. This structure has no installation problems when there is enough space in the equipment site. However, when encountering a small working site or a combination of multiple check valves, the resulting pipeline system is more complex and occupies more space, so there is room for improvement. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the aforementioned background technology by providing an integrated check valve to optimize pipeline layout.

[0004] To achieve the above objectives, this utility model provides an integrated one-way valve structure, which adopts the following technical solution: An integrated one-way valve structure includes a side plate with a vertical hollow design. A valve seat plate is fixedly mounted in the middle of the side plate, and a communication port is provided in the middle of the valve seat plate. A valve core is provided at the communication port to seal and block the communication port. A valve core guide tube is provided at the upper end of the valve core, and a valve core guide post is provided at the lower end of the valve core. An upper cover plate is connected above the side plate, and a discharge port is provided at the center of the upper cover plate. A valve core tube is provided below the upper cover plate, and the valve core guide tube is inserted into the valve core tube. A bottom plate is provided at the lower end of the side plate, and a feed port is provided at the center of the bottom plate. A second valve core is provided at the feed port, and a sleeve is provided at the upper end of the second valve core. The valve core guide post is inserted into the sleeve. A connection port is opened on the side plate for connecting to a working cylinder. The connection port is located between the bottom plate and the valve seat plate. Guide holes are opened on the valve core tube and the valve core guide tube.

[0005] A further improvement of this utility model of an integrated one-way valve structure is that both the connecting port and the feed port are truncated cone-shaped with a larger upper part and a smaller lower part, and the valve core and the second valve core are respectively adapted to the connecting port and the feed port.

[0006] Compared with the prior art, the beneficial effects of this utility model are: This utility model simplifies and compacts the structure by integrating two sets of one-way valves into one unit, making the valve body easy to install and maintain, optimizing the overall pipeline layout, and saving equipment space. Attached Figure Description

[0007] To more clearly illustrate the technical solutions of the embodiments of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and detailed embodiments. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. Among them: Figure 1 A schematic diagram of an existing bypass check valve assembly structure; Figure 2 This is a schematic diagram of the structure of this utility model; In the diagram: 1 side plate, 2 valve seat plate, 3 connecting port, 4 valve core, 5 upper cover plate, 6 valve core guide tube, 7 valve core tube, 8 guide hole, 9 valve core guide post, 10 bottom plate, 11 second valve core, 12 sleeve, 13 working cylinder, 14 feed port, 15 discharge port. Detailed Implementation

[0008] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0009] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0010] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0012] like Figure 2As shown, an integrated one-way valve structure includes a side plate 1 with a vertical hollow design. A valve seat plate 2 is fixedly installed in the middle of the side plate, and a connecting port 3 is provided in the middle of the valve seat plate. A valve core 4 is provided at the connecting port to seal and block the connecting port. A valve core guide tube 6 is provided at the upper end of the valve core, and a valve core guide post 9 is provided at the lower end of the valve core. An upper cover plate 5 is connected above the side plate, and a discharge port 15 is provided at the center of the upper cover plate. A valve core tube 7 is provided below the upper cover plate, and the valve core guide tube is inserted into the valve core tube. A bottom plate 10 is provided at the lower end of the side plate, and a feed port 14 is provided at the center of the bottom plate. A second valve core 11 is provided at the feed port, and a sleeve 12 is provided at the upper end of the second valve core. The valve core guide post is inserted into the sleeve. A connection port is opened on the side plate to connect to a working cylinder 13. The connection port is located between the bottom plate and the valve seat plate. A guide hole 8 is opened on the valve core tube 7 and the valve core guide tube 6.

[0013] The connecting port and the feed port are both truncated cones with a larger top and a smaller bottom. The valve core 4 and the second valve core 11 are respectively adapted to the connecting port and the feed port.

[0014] Preferably, the valve seat plate is welded to the side plate; the upper cover plate is bolted to the side plate; and the bottom plate can be welded to the side plate.

[0015] The working principle of this utility model is as follows: when the piston head in the working cylinder reciprocates, it will draw the material from the feed port into the valve body, and then enter the working cylinder through the bypass pipe. When the piston head reciprocates again, it will discharge the material drawn into the working cylinder, push the valve core to move upward, and allow the material to be discharged smoothly through the discharge port through the valve core guide tube and the guide hole on the valve core tube.

[0016] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.
