[0018] like Figures 1 to 7As shown, an impact-resistant valve cover includes a valve cover main body structure 1, and the lower part of the valve cover main body structure 1 is a flow matching groove in the valve, and an arc-shaped impact-resistant matching groove 2 is provided at the internal upper end position of the flow matching groove in the valve. Its main body is an arc-shaped structure, which can guide and match the fluid when matching with the fluid, so as to achieve a buffering and impact-resistant effect. The arc surface of the impact-resistant matching groove 2 is provided with an arc-shaped reinforced flow guide safety column 3 evenly distributed along the central axis direction of the arc surface, so that the structural strength of the impact-resistant matching groove 2 is better. A fluid conveying guide groove is formed between two adjacent reinforced flow guide safety columns 3, which can divert the fluid and further reduce the impact force when matching with the fluid. The lower left end of the valve cover main body structure 1 is located at the connection position of the reinforced flow guide safety column 3 and is provided with an integrally formed stable sealing matching boss 4, which has better sealing performance when matching. The length of the stable sealing mating boss 4 is the same as the width in the central axis direction of the impact-resistant mating groove 2. The front and rear directions of the valve cover main structure 1 are provided with an integrally formed cylindrical installation auxiliary reinforcement column 5, which can be inserted into the mating hole of the installation position, and can play a role of associating with the mating structure, so that the mating strength of the connection position is higher. The front center position of the installation auxiliary reinforcement column 5 is provided with an installation mating connection hole 6 that completely penetrates the front and rear directions, and is connected with the combined column of the installation position. During installation, this position can be used as a rotation axis for rotation, so as to meet the installation adjustment of different positions. The front of the valve cover main structure 1 is provided with integral fixed mating holes 7 distributed up and down, and the overall fastening is performed through this position. The integral fixed mating hole 7 is located in the right area of ​​the impact-resistant mating groove 2. It sets the position inside the main structure that cooperates with the fluid into an arc-shaped cooperation groove, and adds an arc-shaped guide structure inside, so that when in use, the structural bearing strength of the fluid cooperation position can be guaranteed to be higher, and the fluid can be buffered and cooperated through the arc structure when cooperating with the fluid, and it can be diverted, so that the overall impact resistance of the valve cover is better and the safety during use is higher. The left side of it is provided with a sealing boss structure, so that the sealing stability is better during the cooperation connection, and the fastening position on the right side can be selected and used according to needs. The overall fastening position is adjusted with installation structures of different specifications, which is more convenient during assembly and has higher overall safety and durability during later use.

[0019] When in use, it can be used in conjunction with a complex flow valve, and can also be used in conjunction with other conveying components of a fluid conveying device, making it more convenient to use.

[0020] Preferably, the reinforced guide safety column 3 is connected to the valve cover main structure 1 in an integrally formed manner, so that the structural support strength at the connection position is better, the service life is longer during use, and the matching stability is more reliable.

[0021] Preferably, the lower end of the mounting fitting connection hole 6 penetrates the lower end surface of the valve cover main structure 1, so that this position is more convenient for fitting and the assembly efficiency is higher.
