[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a new type of conical guide valve for a mud pump, including a main body 1, which adopts a truncated cone main body 1, the upper plane of the main body 1 has an annular sealing groove 1a, the upper center is an assembly positioning surface 1b, the lower center is an assembly shaft hole 1c, three guide arms 2 are evenly distributed on the outside of the main body 1, the part connected to the main body 1 is the guide arm connecting rib 2a, and the outermost end is the guide arm contact block 2b:
[0018] Specifically, the conical guide valve is mainly composed of a main body 1, and its uniqueness lies in the truncated cone design. This design not only makes the mud pump more stable during operation, but also helps to reduce the resistance of the fluid in the valve body and improve the flow and pressure of the mud pump. An annular sealing groove 1a is designed on the upper plane of the main body 1, which can effectively prevent the mud pump from leaking during operation and ensure the continuous and stable operation of the mud pump. At the same time, the assembly positioning surface 1b at the upper center and the assembly shaft hole 1c at the lower center make the installation and disassembly of the conical guide valve more convenient and quick, and improve the maintenance efficiency of the mud pump. Three guide arms 2 are evenly distributed on the outside of the main body 1, which not only enhances the structural strength of the conical guide valve, but also makes the mud pump more stable during operation. The connection part between the guide arm connecting rib 2a and the main body 1 is made of high-strength material to ensure the stability and durability of the guide arm. The guide arm contact block 2b is made of wear-resistant material, which effectively extends the service life of the guide valve.
[0019] Reference Figure 1 and Figure 2 The main body 1 is a nearly truncated cone structure, with an annular sealing groove 1a on the upper plane, which plays a sealing role by installing an O-ring when cooperating with other components. The upper center of the main body 1 is an assembly positioning surface 1b, which ensures the installation size by plane limit when cooperating with other components. The lower center of the main body 1 is an assembly shaft hole 1c, which is used to cooperate with the central shaft:
[0020] Specifically, the main body 1 of the truncated cone structure provides a solid and reliable foundation for the cooperation between mechanical parts. An annular sealing groove 1a is provided on the upper plane of the main body 1. When the main body 1 cooperates with other parts, the annular sealing groove 1a can effectively prevent liquid or gas from leaking from the joint surface, thereby ensuring the normal operation and long life of the mechanical equipment. There is also an assembly positioning surface 1b in the central upper part of the main body 1, which ensures the accuracy of the installation dimensions through the plane limit cooperation with other parts. An assembly shaft hole 1c is designed in the central lower part of the main body 1. This shaft hole is a key part for cooperation with the center shaft. The precise design and manufacture of the assembly shaft hole 1c are crucial to ensure the cooperation accuracy between the center shaft and the main body 1. Through the cooperation between the shaft hole and the center shaft, the functions of rotation, transmission or support between mechanical parts can be realized, thereby meeting the working requirements of mechanical equipment.
[0021] Reference Figure 1 and Figure 2 The guide arm 2 and the central axis hole have an angle of 60°. The guide arm connecting rib 2a gradually changes in size from the root to the tip. The outermost end of the guide arm 2 is the guide arm contact block 2b. The guide arm contact block 2b is square, and the outermost is the friction contact surface. The hardness is increased by high-frequency quenching to ensure wear resistance.
[0022] Specifically, three guide arms 2 are evenly distributed on the outside of the main body 1, which can provide good support and stability in practical applications. The angle between each guide arm 2 and the central axis hole is 60°. This angle design enables the guide arm to disperse the pressure more evenly when subjected to force, thereby improving the stability of the overall structure. The connection part between the guide arm and the main body adopts the design of the guide arm connecting rib 2a, which not only ensures the firmness of the connection, but also enables the guide arm to have a certain elastic deformation when subjected to external force, thereby playing a buffering role. The contact block of the guide arm contact block 2b is square, and the outermost is the friction contact surface. In order to improve the wear resistance of the friction contact surface, the guide arm contact block can also maintain good friction performance under long-term, high-load working environment, thereby ensuring the stability and service life of the guide arm.
[0023] Working principle: The unique design of the main body 1 of the truncated cone structure ensures a close fit with other components and realizes the sealing and positioning functions. The upper plane of the main body 1 is provided with an annular sealing groove 1a, which uses an O-ring to seal to prevent liquid or gas leakage. It is simple and reliable, with low maintenance costs, and is widely used in mechanical sealing occasions. There is an assembly positioning surface 1b at the upper center to control the installation size, improve assembly efficiency, and ensure the stability and reliability of the equipment. The lower center is the assembly shaft hole 1c, which cooperates with the central axis to realize the rotation and positioning functions and ensure the normal operation of the equipment. Three guide arms 2 are evenly distributed on the outside, with an angle of 60°, which smoothly guide the movement of the main body 1 and reduce friction and wear. The size of the guide arm connecting rib 2a changes gradually to ensure strength, reduce weight, and improve efficiency. The guide arm contact block 2b is the outer end part, with a square design. The friction contact surface is high-frequency quenched to improve hardness, ensure wear resistance, and extend the life of the equipment.
[0024] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
