[0019] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0020] It should be clear that the described implementations are only part of the implementations of the utility model, not all of the implementations. Based on the implementations in the utility model, all other implementations obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0021] The reversing valve of the cone valve type filling pump can be composed of a suction valve, a pressure valve and two pairs of cone valves. The pressure valve plays the role of receiving the output of high-pressure slurry. In the pressure valve, the slurry enters the output port from the left and right feed ports in turn according to the reversing frequency. During operation, the pressure valve is continuously impacted and flushed by the high-pressure slurry, so that it has higher reliability requirements. The embodiment of the utility model provides a pressure valve housing of a cone valve type filling pump, which can reduce the risk of deformation and damage caused by the impact of high-pressure filling materials.

[0022] The following combination Figures 1 to 3 , the implementation mode of the utility model is further explained.

[0023] Figure 1 The schematic diagram of the structure of the pressure valve housing of the cone valve type filling pump of the utility model is shown. Figure 1As shown, the pressure valve housing of the cone valve type filling pump of the present embodiment, the first end of the pressure valve housing is provided with a first feed port 1 and a second feed port 2, and the second end of the pressure valve housing is provided with a discharge port 3; the first feed port 1 is connected with the discharge port 3 through a first filling material cavity 4, and the second feed port 2 is connected with the discharge port 3 through a second filling material cavity 5; the inner wall of the first feed port 1 is provided with a first annular bearing portion 101, the first annular bearing portion 101 is used to place the first cone valve ring seat 12, and the first annular bearing portion 101 includes a first ring removal groove 102; the inner wall of the second feed port 2 is provided with a second annular bearing portion 201, the second annular bearing portion 201 is used to place the second cone valve ring seat 13, and the second annular bearing portion 201 includes a second ring removal groove 202.

[0024] The pressure valve housing may be an integral streamlined casting with a wall thickness capable of withstanding the working pressure. The first feed port 1 and the second feed port 2 may be respectively used to connect to the material cylinder, and the discharge port 3 may be used to connect to the filling pipe. The end faces of the first cone valve ring seat 12 and the second cone valve seat may not protrude from the end face of the first end of the pressure valve housing.

[0025] The first annular bearing part 101 may include one or more first ring-taking grooves 102, and the second annular bearing part 201 may include one or more second ring-taking grooves 202. Exemplarily, in one embodiment, the first annular bearing part 101 includes two symmetrically arranged first ring-taking grooves 102, and the second annular bearing part 201 includes two symmetrically arranged second ring-taking grooves 202.

[0026] The first cone valve ring seat 12 provided in the first feed port 1 can be snap-fitted with the inner wall of the first feed port 1, for example, the first cone valve ring seat 12 and the inner wall of the first feed port 1 are assembled with clearance fit. The connection and assembly method between the second cone valve ring seat 13 and the inner wall of the second feed port 2 is basically the same as the connection and assembly method between the first cone valve ring seat 12 and the inner wall of the first feed port 1, and will not be repeated here.

[0027] In order to facilitate the removal of the first cone valve ring seat 12 from the first feed inlet 1, a lifting ring hole can generally be drilled on the surface of the cone seat or the end face of the first end of the first feed inlet 1, but this will reduce the structural strength of the pressure valve housing.

[0028] The pressure valve housing of the cone valve type filling pump provided by the embodiment of the utility model has a first annular bearing portion 101 provided on the inner wall of the first feed port 1, and the first annular bearing portion 101 includes a first ring removal groove 102, so as to facilitate the removal of the first cone valve ring seat 12; a second annular bearing portion 201 is provided on the inner wall of the second feed port 2, and the second annular bearing portion 201 includes a second ring removal groove 202, so as to facilitate the removal of the second cone valve ring seat 13. In this way, by arranging the first ring removal groove 102 on the inner wall of the first feed port 1 and arranging the second ring removal groove 202 on the inner wall of the second feed port 2, the structural strength of the pressure valve housing can be improved, and the risk of deformation and damage thereof due to the impact of high-pressure filling material can be reduced.

[0029] See also Figure 2 As shown, in order to improve the structural strength of the pressure valve housing, in some embodiments, the first annular bearing portion 101 is disposed at the bottom of the first feed port 1 , and the second annular bearing portion 201 is disposed at the bottom of the second feed port 2 .

[0030] See also Figure 3 As shown, in some embodiments, the notch of the first ring taking groove 102 faces the axis of the first feed port 1; the notch of the second ring taking groove 202 faces the axis of the second feed port 2, so that the operator can easily enter the first ring taking groove 102 or the second ring taking groove 202 through the notch, thereby taking out the first cone valve ring seat 12 through the first ring taking groove 102, or taking out the second cone valve ring seat 13 through the second ring taking groove 202.

[0031] See also Figure 2 As shown, in order to increase the structural strength of the first annular bearing part 101, in some embodiments, the first ring-taking groove 102 is provided on the surface of the first annular bearing part 101 close to the first end, and the depth of the first ring-taking groove 102 is less than the thickness of the first annular bearing part 101. In this way, compared with the first ring-taking groove 102 penetrating the first annular bearing part 101, the risk of stress concentration in the part of the first annular bearing part 101 close to the first ring-taking groove 102 can be reduced, thereby increasing the structural strength of the first annular bearing part 101.

[0032] In some embodiments, the second ring-taking groove 202 is disposed on the surface of the second annular bearing portion 201 close to the first end, and the depth of the second ring-taking groove 202 is less than the thickness of the second annular bearing portion 201. The technical effect of the second ring-taking groove 202 provided in this embodiment is substantially the same as the technical effect of the embodiment of the first ring-taking groove 102, and will not be described in detail herein.

[0033] Exemplarily, the depth of the first ring-removing groove 102 may be one third of the thickness of the first annular bearing portion 101 , and the depth of the second ring-removing groove 202 may be one third of the thickness of the second annular bearing portion 201 .

[0034] See also Figure 2 As shown, in some embodiments, the inner walls of the first filling material cavity 4 and the second filling material cavity 5 can be smooth curved surfaces, so that the inner walls of the first filling material cavity 4 and the second filling material cavity 5 can gradually change the flow direction of the filling material entering the first filling material cavity 4 and the second filling material cavity 5, thereby dispersing the impact force of the filling material, reducing the direct impact of the filling material on the inner cavity of the first filling material cavity 4 and the second filling material cavity 5, and reducing the risk of the first filling material cavity 4 and the second filling material cavity 5 being deformed and damaged by the impact of high-pressure filling material.

[0035] Exemplarily, the cross-sectional profile of the first filling material cavity 4 is connected with the cross-sectional profile of the second filling material cavity 5 to form a heart shape.

[0036] In some embodiments, the inner walls of the first filling material cavity 4 and the second filling material cavity 5 may be provided with a wear-resistant alloy layer to extend the service life of the pressure valve housing.

[0037] The impact force of the filling material on the pressure valve housing is different in different directions. In order to prevent the position of the pressure valve housing that is subjected to greater impact force from being damaged, in some embodiments, a reinforcing rib plate is provided on the outside of the pressure valve housing along the feeding direction. In this way, when the filling material is supplied and the filling material in a high-pressure state impacts the pressure valve housing, the reinforcing rib plate can thicken and stabilize the pressure valve housing, further provide impact support, and reduce the risk of deformation and damage caused by the impact of the high-pressure filling material.

[0038] In some embodiments, the reinforcing rib plate includes a first reinforcing rib plate 6 provided on the first side of the pressure valve housing and on the opposite side of the first side; the first reinforcing rib plate 6 includes a first portion fitted to the outside of the columnar portion of the pressure valve housing, a second portion fitted to the outside of the conical portion of the pressure valve housing, and a third portion transitionally connecting the first portion and the second portion. In this way, the first reinforcing rib plate 6 can be fully fitted to the outer side of the pressure valve housing, so that the pressure valve housing can effectively transfer the impact force it bears to the first reinforcing rib plate 6, giving full play to the thickening and stabilizing effect of the first reinforcing rib plate 6 on the pressure valve housing, and reducing the risk of deformation and damage of the pressure valve housing due to the impact of high-pressure filling material.

[0039] The first side of the pressure valve housing may also be referred to as a short side or a wide side of the pressure valve housing.

[0040] See also Figure 1 As shown, in order to prevent the weak part of the first side of the pressure valve housing from being damaged, in some embodiments, the first part of the first reinforcing rib plate 6 is fixed to the bottom of the first end of the pressure valve housing, and the second part is arranged close to the discharge port 3 to fully thicken and stabilize the weak part of the first side of the pressure valve housing.

[0041] In some embodiments, the first part, the second part and the third part of the reinforcing rib plate have the same thickness. In this way, the first reinforcing rib plate 6 is fully fitted with the outer side of the pressure valve housing, which effectively thickens and stabilizes the pressure valve housing, thereby reducing the production cost of the pressure valve housing.

[0042] In some embodiments, the reinforcing rib plate includes a second reinforcing rib plate 7 provided on the second side of the pressure valve housing and on the opposite side of the second side; the width of the second side of the pressure valve housing is greater than the width of the first side of the pressure valve housing. The second side of the pressure valve housing can also be referred to as the long side of the pressure valve housing.

[0043] The pressure valve housing's discharge port 3 is subject to a high impact pressure from the filling material. Figure 1 As shown, in one embodiment, the second reinforcing rib plate 7 is a V-shaped rib plate or a U-shaped rib plate, the open end of the V-shaped rib plate or the U-shaped rib plate is fixed to the bottom of the first end of the pressure valve housing, and the closed end is arranged close to the discharge port 3. The closed end of the V-shaped rib plate or the U-shaped rib plate can withstand a greater impact pressure than the open end of the V-shaped rib plate or the U-shaped rib plate. In this way, the weak point of the second side of the pressure valve housing can be fully thickened and stabilized.

[0044] During the production process, a first cone valve can be arranged in the first filling material chamber 4 of the pressure valve housing, and a second cone valve can be arranged in the second filling material chamber 5. To facilitate the first valve stem of the first cone valve to extend from the first filling material chamber 4 and be connected to the drive assembly, and the second valve stem of the second cone valve to extend from the second filling material chamber 5 and be connected to the drive assembly, in some embodiments, a first valve stem mounting hole 8 and a second valve stem mounting hole 9 are provided at the second end of the pressure valve housing, the first valve stem mounting hole 8 is connected to the first filling material chamber 4, and the second valve stem mounting hole 9 is connected to the second filling material chamber 5.

[0045] See also Figure 2 As shown, in some embodiments, the first valve stem mounting hole 8 is coaxially arranged with the first feed port 1, and the second valve stem mounting hole 9 is coaxially arranged with the second feed port 2. In this way, during the production process, the axes of the first valve stem mounting hole 8, the first cone valve and the first feed port 1 in the first valve stem mounting hole 8 coincide with each other. In this way, compared with the case where the axes of the three do not coincide, the use of the first valve stem with a curved portion can reduce the turbulence generated by the valve stem of the first cone valve, making the flow of the filling material more stable. At the same time, the coincidence of the axes of the three can facilitate the installation, debugging and maintenance of the operator in the process of applying the first cone valve to the pressure valve housing during the production process.

[0046] The openings of the first valve stem mounting hole 8 and the second valve stem mounting hole 9 may cause stress concentration in the pressure valve housing. In order to enhance the structural strength of the pressure valve housing, see Figure 1As shown, in some embodiments, the pressure valve housing includes a first reinforcement protrusion 10 and a second reinforcement protrusion 11 extending from the side of the pressure valve housing toward the second end of the pressure valve housing, the first valve stem mounting hole 8 is provided on the first reinforcement protrusion 10, and the second valve stem mounting hole 9 is provided on the second reinforcement protrusion 11. Exemplarily, the first reinforcement protrusion 10 and the second reinforcement protrusion 11 may be in the shape of a rectangular platform.

[0047] In one embodiment, the second portion of the first reinforcing rib plate on the first side of the pressure valve housing may be fixed to the first reinforcing protrusion, and the second portion of the first reinforcing rib plate on the opposite side of the first side of the pressure valve housing may be fixed to the second reinforcing protrusion.

[0048] The pressure valve housing of the cone valve type filling pump provided in the embodiment of the utility model has a filling material cavity between the inlet and the outlet 3 with a smooth curved surface, which can realize a smooth transition of the filling material from the inlet to the outlet 3, facilitate feeding and conveying through the pressure valve, and reduce the impact force of the filling material on the pressure valve housing; the side of the pressure valve housing is provided with a reinforcing rib plate, which can thicken and stabilize the weak parts of the pressure valve housing to ensure the structural strength of the pressure valve housing.
