Description

Technical Field

[0001] This utility model relates to the field of bypass check valve technology, specifically a ball valve core sealing structure for a bypass check valve used in the high-concentration sludge industry. Background Technology

[0002] Currently, the bypass check valve core used in the high-concentration sludge industry is generally a plate-type valve core, as shown in the attached image. Figure 1 As shown, this valve core has a planar sealing structure. In actual use, due to the large plate area, the gap between the side of the valve core and the inner wall of the check valve is small. High-concentration sludge material is easy to accumulate here, causing blockage and preventing the plate valve core from moving up and down normally. This affects the opening and closing of the bypass check valve, which in turn may cause the equipment to be shut down. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the aforementioned background technology by providing a bypass-type one-way valve ball valve core sealing structure that is less prone to clogging by concentrated sludge and ensures working efficiency.

[0004] To achieve the above objectives, this utility model provides a ball valve core sealing structure for a bypass-type one-way valve used in the high-concentration sludge industry, which adopts the following technical solution: A bypass-type one-way valve ball valve core sealing structure for high-concentration sludge industry includes a valve body with an inner cavity. The valve body has an inlet on its lower end face and an outlet on one side end face. The inlet and outlet are connected to the inner cavity. A notch is opened on the upper end face of the valve body, and an upper cover plate is provided at the notch. Four sets of vertically arranged guide rods are fixedly connected to the lower end face of the upper cover plate. The four sets of guide rods are distributed at four corners. A ball valve core is provided between the four sets of guide rods. The ball valve core is used to block and seal the inlet. A retaining ring is provided at the lower end of the four sets of guide rods, and the retaining ring limits the ball valve core.

[0005] A further improvement of the ball valve core sealing structure of the bypass one-way valve for the high-concentration sludge industry of this utility model is that a polyurethane gasket is also provided on the lower end face of the upper cover plate.

[0006] A further improvement of the ball valve core sealing structure of the bypass one-way valve for the high-concentration sludge industry of this utility model is that the guide rod passes through the polyurethane gasket.

[0007] A further improvement of the ball valve core sealing structure of the bypass one-way valve for the high-concentration sludge industry is that a conical valve seat is provided at the discharge port. The middle part of the conical valve seat is hollow and connected to the discharge port. An arc-shaped part is provided at the upper part of the hollow part of the conical valve seat. The arc-shaped part is adapted to fit and seal with the ball valve core.

[0008] Compared with the prior art, the beneficial effects of this utility model are: This invention uses a ball as the valve core. Because the valve core has a spherical structure, the space between it and the inner wall of the one-way valve is relatively large, which makes it less likely to be blocked by thick sludge, thus ensuring the normal use of the equipment.

[0011] 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.

[0012] 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.

[0013] 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.

[0014] like Figure 2As shown, a ball valve core sealing structure for a bypass-type check valve in the high-concentration sludge industry includes a valve body 1, an inner cavity 2 within the valve body, an inlet 3 on the lower end face of the valve body, and an outlet 4 on one side end face of the valve body. The inlet and outlet are connected to the inner cavity. A notch is formed on the upper end face of the valve body, and an upper cover plate 5 is provided at the notch. This structure is one of the conventional structures of existing check valves. Further, four sets of vertically arranged guide rods 6 are fixedly connected to the lower end face of the upper cover plate. The fixed connection method can be threaded connection, i.e., the upper end of the guide rod has a threaded part, and the upper cover plate has a threaded groove. The four sets of guide rods are distributed at four corners, and a ball valve core 7 is provided between the four sets of guide rods. The ball valve core is used to block and seal the inlet. A retaining ring 8 is provided at the lower end of the four sets of guide rods, and the retaining ring limits the ball valve core. The guide rods are used to limit the up and down sliding of the ball valve core. The retaining ring prevents the ball valve core from disengaging from the guide rod's limit. The retaining ring also ensures the connection strength between the four guide rods.

[0015] Furthermore, a polyurethane pad 11 is provided on the lower end face of the upper cover plate. Preferably, the guide rod passes through the polyurethane pad.

[0016] Furthermore, a conical valve seat 9 is provided at the discharge port. The hollow center of the conical valve seat is connected to the discharge port, and an arc-shaped part 10 is provided at the upper part of the hollow center. The arc-shaped part is adapted to fit and seal with the ball valve core. The design of the conical valve seat and the arc-shaped part ensures effective sealing when the ball valve core falls.
