Obviously, the embodiments described below are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A high-pressure pump shock-absorbing valve comprises a high-pressure pump body 1, a driving motor body 2 is arranged on the top surface of the high-pressure pump body 1, a shock-absorbing valve body 5 is fixed to the bottom end of the high-pressure pump body 1, a fixed base 3 is arranged below the shock-absorbing valve body 5, the fixed base 3 is fixedly connected to the ground by a fixing screw 4, an inner sleeve limit block 6 is fixed on the top surface of the fixed base 3, the inner sleeve limit block 6 is slidably connected to the inside of the shock-absorbing valve body 5, four limit rods 7 are symmetrically fixed on the top surface of the fixed base 3, each limit rod 7 is sleeved with a first shock-absorbing spring 8, the bottom end of the first shock-absorbing spring 8 is fixedly connected to the fixed base 3, and the other end of the first shock-absorbing spring 8 is fixedly connected to the bottom surface of the high-pressure pump body 1, so that the vibration generated by the operation of the high-pressure pump body 1 is absorbed by the first shock-absorbing spring 8.
[0024] Specifically, a rubber shock-absorbing pad 9 is fixed to the top surface of the inner sleeve limit block 6. The rubber shock-absorbing pad 9 is located directly below the bottom surface of the shock-absorbing valve body 5 and is fixed with a buckle that is shaped to match the ground of the shock-absorbing valve body 5. Another rubber shock-absorbing pad 9 is fixed to the bottom surface of the buckle of the inner sleeve limit block 6, so that the rubber shock-absorbing pad 9 absorbs the vibration generated by the contact between the shock-absorbing valve body 5 and the fixed base 3.
[0025] As an optimization solution, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a fixing plate 10 is fixed to the top of the driving motor body 2, and upper inner sleeve rods 12 are fixed at both ends of the bottom surface of the fixing plate 10, an outer sleeve rod 11 is slidably sleeved below the upper inner sleeve rod 12, and a lower inner sleeve rod 13 is slidably sleeved at the bottom end of the outer sleeve rod 11, and the lower inner sleeve rod 13 is fixedly connected to the bottom end of the high-pressure pump body 1, and connecting plates fixed to the inner sleeve rod 13 are symmetrically fixed to the bottom end of the high-pressure pump body 1, and the outer ends of the two connecting plates are flush with the two ends of the fixing plate 10, so that the outer sleeve rod 11 transmits the vibration generated by the driving motor body 2 to the shock-absorbing valve body 5 for shock absorption.
[0026] Specifically, a partition block 16 is fixed to the middle section of the outer sleeve rod 11, and a second shock-absorbing spring 14 and a third shock-absorbing spring 15 are fixed to the top and bottom surfaces of the partition block 16 respectively. The top end of the second shock-absorbing spring 14 is fixedly connected to the bottom end of the upper inner sleeve rod 12, and the bottom end of the third shock-absorbing spring 15 is fixedly connected to the top end of the lower inner sleeve rod 13. The radii of the upper inner sleeve rod 12 and the lower inner sleeve rod 13 are both smaller than the radius of the inner circle of the outer sleeve rod 11, so that the second shock-absorbing spring 14 and the third shock-absorbing spring 15 weaken the vibration generated by the drive motor body 2.
[0027] Working principle: When the high-pressure pump body 1 vibrates during operation, the high-pressure pump body 1 drives the shock-absorbing valve body 5 to vibrate. At the same time, the first shock-absorbing spring 8 is fixedly connected to the bottom end of the high-pressure pump body 1, so that the first shock-absorbing spring 8 absorbs the vibration generated by the high-pressure pump body 1 and rebounds with the same force to offset the vibration. At the same time, the first shock-absorbing spring 8 moves in the limit rod 7 to prevent the first shock-absorbing spring 8 from escaping from the limit rod 7. At the same time, the shock-absorbing valve body 5 vibrates on the inner sleeve limit block 6. When the bottom end of the shock-absorbing valve body 5 contacts the bottom end of the fixing screw 4 due to vibration, the rubber shock-absorbing pad 9 absorbs the vibration of the shock-absorbing valve body 5. The vibration caused by the contact between the main body 5 and the fixing screw 4, and at the same time, when the driving motor main body 2 is working and generating vibration, the vibration is transmitted by the fixing plate 10 to the upper inner sleeve rod 12 at both ends, so that the upper inner sleeve rod 12 slides inside the lower inner sleeve rod 13. At this time, the second shock-absorbing spring 14 absorbs and weakens the vibration of the driving motor main body 2 transmitted through the upper inner sleeve rod 12, and absorbs and weakens the remaining vibration through the bottom end of the outer sleeve rod 11 and then through the third shock-absorbing spring 15, and then transmits it to the shock-absorbing valve main body 5 through the lower inner sleeve rod 13, and then through the first shock-absorbing spring 8 for shock absorption.
