For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0032] like Figures 1 to 3 As shown, the utility model provides a pressure stabilizing device for stabilizing the output pressure of a fluid, the pressure stabilizing device comprising a tubular housing 10, a flow blocking seat 20 fixed to the housing 10, a pressure regulating frame 30 slidably connected to the flow blocking seat 20, and an elastic member 40 sleeved on the pressure regulating frame 30. The housing 10 is provided with a flow guiding channel 16, a water inlet end 11 located at one end of the flow guiding channel 16, and a water outlet end 12 located at the other end of the flow guiding channel 16, the water inlet end 11 is used to be connected to a water inlet pipe, and the water outlet end 12 is used to be connected to a water outlet pipe.
[0033] The flow guide channel 16 is arranged along the center line direction of the housing 10, and the flow blocking seat 20 is located in the flow guide channel 16. Specifically, the flow blocking seat 20 is fixed to one end of the flow guide channel 16 located at the water outlet end 12, so that the flow guiding part of the flow blocking seat 20 is close to the water inlet end 11. The flow blocking seat 20 is provided with a flow blocking channel 21, which is a channel structure for fluid circulation, and the maximum aperture of the flow blocking channel 21 is smaller than the aperture of the flow guide channel 16.
[0034] The blocking seat 20 is provided with a blocking end 23 on the side facing the water inlet end 11, and a stepped end plate is provided on the end surface of the blocking end 23. At least one regulating port 22 is provided laterally with the blocking flow channel 21, and the regulating port 22 is a long slot hole, and the center line of the regulating port 22 and the center line of the blocking flow channel 21 intersect obliquely. Preferably, the center line of the regulating port 22 and the center line of the blocking flow channel 21 intersect vertically. The blocking seat 20 performs preliminary blocking adjustment on the fluid input to the pressure stabilizing device through the blocking end 23 to reduce the fluid impact force and pressure, and the fluid enters the pressure regulating channel 31 of the booster frame from the lateral regulating port 22.
[0035] The pressure regulating frame 30 slides in the flow blocking channel 21, and the pressure regulating frame 30 is provided with a pressure regulating channel 31, and the pressure regulating channel 31 is connected with the regulating port 22. One end of the elastic member 40 elastically abuts against the flow blocking seat 20, and the other end of the elastic member 40 elastically abuts against the pressure regulating frame 30. Among them, the pressure regulating channel 31 includes a fluid portion 311 and a cone portion 312 gradually increasing from the fluid portion 311, and the cone portion 312 faces the water outlet 12. The regulating port 22 is located within the sliding range of the pressure regulating frame 30. When the pressure at the water outlet 12 exceeds a preset value, the fluid pressure at the water outlet 12 pushes the pressure regulating frame 30 to move toward the regulating port 22 through the cone portion 312. When the pressure regulating frame 30 moves to the regulating port 22 area, the flow rate of the fluid passing through the regulating port 22 is reduced, thereby reducing the output pressure of the water outlet 12, and maintaining balance when the output pressure of the water outlet 12 is substantially the same as the preset value.
[0036] The elastic member 40 elastically pushes the pressure regulating frame 30 toward the water outlet 12. After the pressure at the water outlet 12 exceeds the preload force of the elastic member 40, the pressure regulating frame 30 moves toward the regulating port 22 and reduces the fluid output, thereby keeping the pressure at the water outlet 12 basically consistent, achieving self-balancing and convenient pressure regulation.
[0037] In one embodiment, the housing 10 further includes an adjustment seat 50, the adjustment seat 50 abuts against the pressure regulating frame 30, and the connector 15 abuts against the adjustment seat 50. The adjustment seat 50 pushes the pressure regulating frame 30 to move, so that the elastic preload force can achieve preload adjustment, and then adjust the overall output pressure value of the pressure stabilizing device, so that the pressure adjustment of the water outlet 12 is convenient.
[0038] like Figures 2 to 4 As shown, in one embodiment, the flow blocking end 23 includes an end panel 231, a plurality of spaced convex ribs 233 protruding from the end panel 231, and a top plate 232 connected to the spaced convex ribs 233, and the end panel 231 and the top plate 232 are located at both ends of the spaced convex ribs 233. The end panel 231 and the top plate 232 are arranged opposite to each other, wherein the area of the top plate 232 is smaller than the area of the end panel 231, and optionally, the area of the top plate 232 is greater than or equal to the minimum aperture of the pressure regulating channel 31, so as to prevent the fluid of the water inlet end 11 from directly entering the pressure regulating channel 31.
[0039] Preferably, the spacing ribs 233 are arranged along the radial direction of the flow-blocking channel 21, and the regulating port 22 is formed between two adjacent spacing ribs 233, and the flow-blocking channel 21 intersects with the end plate 231. Due to the arrangement of the spacing ribs 233 and the top plate 232, the impact force and flow velocity of the fluid can be reduced. The fluid changes direction at the regulating port 22, and then adjusts the volume change of the fluid part 311 and the cone part 312 to achieve self-regulation of the fluid output pressure, reduce the complexity of fluid pressure regulation in the pipeline, and have low pressure stabilization cost and low failure rate.
[0040] Preferably, four spacing ribs 233 are provided, and the radial length of the four spacing ribs 233 is the same as the end surface size of the end panel 231.

In one embodiment, the voltage stabilizing device includes a mounting seat 70 embedded in the flow blocking seat 20, and the elastic member 40 is elastically connected to the mounting seat 70. The end panel 231 protrudes toward the inside of the mounting portion to form a snap-fit convex rib, and the mounting seat 70 is inserted into the gap between the snap-fit convex rib and the mounting portion. The mounting seat 70 is provided with a sealing member 60, and the sealing member 60 is slidably sealed with the outer wall of the voltage regulating frame 30. The mounting seat 70 is provided with a positioning convex rib toward the snap-fit convex rib, and the sealing member 60 is jointly limited by the limiting convex rib and the end face of the snap-fit convex rib to prevent the fluid from entering the space of the elastic member 40.
[0042] In one embodiment, the voltage stabilizing device includes a sliding seal 32 installed on the pressure regulating frame 30, and the sliding seal 32 elastically seals the sliding surface between the pressure regulating frame 30 and the flow blocking channel 21. The sliding seal 32 can prevent the fluid at the output end from flowing back into the activity space of the elastic member 40. Thus, the space where the elastic member 40 is located is kept free of fluid, and the accuracy of the elastic preload force is maintained.
[0043] Furthermore, the sliding seal 32 is provided with two unfolded sealing tongues, and a sealing opening is formed between the two sealing tongues toward the water outlet 12. The sliding seal 32 uses two sealing tongues to achieve multiple seals, and the sealing tongues are unfolded toward the water outlet 12, so as to realize an annular sealing structure with good sealing effect.
