[0002] The stainless steel pressure reducing valve controls the opening of the opening and closing parts in the valve body to adjust the flow of the medium and reduce the pressure of the medium. At the same time, it uses the pressure behind the valve to adjust the opening of the opening and closing parts to keep the pressure behind the valve within a certain range, and sprays cooling water into the valve body or behind the valve to reduce the temperature of the medium. This valve is called a pressure reducing and temperature reducing valve.
[0003] When adjusting the fluid pressure inside the existing stainless steel pressure reducing valve, it is necessary to repeatedly rotate the adjusting component to change the pressure of the internal fluid, and judge whether the adjusted fluid pressure is suitable for the actual required pressure based on the pressure component. When the input fluid pressure is too large, it is difficult to quickly and effectively adjust the fluid pressure to the required pressure by a single adjusting component. Therefore, the existing stainless steel pressure reducing valve lacks the pre-fine adjustment function and is inconvenient to use. For this reason, we provide a stainless steel pressure reducing valve with fine adjustment. Utility Model Content

[0025] like Figure 1-Figure 5As shown, the utility model provides a technical solution: a stainless steel pressure reducing valve with fine adjustment, comprising: a pressure reducing valve body 1, one end of the pressure reducing valve body 1 is fixedly connected to an input pipe 2, an adjusting mechanism 4 is arranged on the top of the input pipe 2, the adjusting mechanism 4 comprises an external shell 41, the external shell 41 is fixedly connected to the input pipe 2, a worm 42 is penetrated inside the external shell 41, a side surface of the worm 42 is meshingly connected to a worm wheel 43, a rotating rod 44 is fixedly connected to the bottom of the worm wheel 43, the rotating rod 44 penetrates the external shell 41 and the inside of the input pipe 2, an O-ring 1 45 is sleeved on the outer surface of the rotating rod 44, an O-ring 2 46 is sleeved on the outer surface of the rotating rod 44, and a An O-ring 2 46 and an O-ring 1 45 are matched in an installation groove, one end of the rotating rod 44 away from the worm gear 43 is fixedly connected to a butterfly valve 47, a fixing block 48 is provided at the bottom of the butterfly valve 47, the fixing block 48 is fixedly connected to the inner wall of the input pipe 2, a rotating shaft 49 is fixedly connected to the bottom of the butterfly valve 47, the rotating shaft 49 is sleeved inside the fixing block 48, the rotating shaft 49 is rotatably connected to the fixing block 48, a bearing 1 401 is passed through the outer surface of the rotating rod 44, the bearing 1 401 is fixedly connected to the outer surface of the rotating rod 44 and the inner wall of the external shell 41, a bearing 2 402 is passed through the outer surface of one end of the worm 42, the bearing 2 402 is fixedly connected to the outer surface of the worm 42 and the inner wall of the external shell 41.
[0026] In this embodiment, by providing an adjustment mechanism 4, the flow rate and pressure of the fluid in the input pipe 2 can be roughly adjusted, so as to be used in conjunction with the pressure reducing valve body 1. The rotation of the worm 42 is used to drive the worm wheel 43, and then the worm wheel 43 can make the rotating rod 44 drive the butterfly valve 47 to rotate while rotating, so as to change the throttling area of the butterfly valve 47. At the same time, a rotating shaft 49 is provided at the bottom of the butterfly valve 47, and the rotating shaft 49 is rotatably connected to the fixed block 48. Then, under the action of the fixed block 48, the impact of the fluid on the butterfly valve 47 will not affect the squeezing of the O-ring 1 45 and the O-ring 2 46 by the rotating rod 44, so that the contact and squeezing of the rotating rod 44 with the O-ring 1 45 and the O-ring 2 46 is uniform, and then there will be no leakage at the rotating rod 44.
[0027] Example 2
[0028] like Figure 1-Figure 4As shown, the other end of the pressure reducing valve body 1 is fixedly connected to the output pipe 3, and an auxiliary mechanism 5 is provided on one side of the external shell 41. The auxiliary mechanism 5 includes a connecting ring 51, which is sleeved on the outer surface of the worm 42, and the connecting ring 51 is fixedly connected to the worm 42. An arc block 52 is fixedly connected to one side of the connecting ring 51, and a rotating block 53 is fixedly connected to the end of the arc block 52 away from the connecting ring 51. The number of the rotating blocks 53 and the arc blocks 52 is two, and the rotating blocks 53 and the arc blocks 52 pass through the interior of the external shell 41.

When the worm 42 rotates, the connecting ring 51 drives the arc block 52 and the rotating block 53 to rotate in the rotating groove provided inside the external shell 41. Therefore, when the arc block 52 and the rotating block 53 rotate, they can limit the worm 42 and ensure the stability of the rotation of the worm 42.
[0030] Working principle:
[0031] like Figure 1-Figure 5 As shown, when the utility model is in use, the throttling area of the butterfly valve 47 in the regulating mechanism 4 can be adjusted according to the actual required pressure of the fluid, and the worm 42 is driven to rotate by rotating the turntable 54. At this time, the worm 42 uses the connecting ring 51 to drive the arc block 52 and the rotating block 53 to rotate in the rotating groove opened inside the external shell 41, and cooperates with the bearing 2 402 to ensure the stability of the rotation of the worm 42. At the same time, the worm 42 also meshes and drives the worm 42, so that the worm wheel 43 drives the rotating rod 44 to rotate. At this time, the rotating The rod 44 will drive the inner diameter ring of the bearing 401 to rotate, and at the same time drive the butterfly valve 47 to rotate in the input pipe 2, and drive the rotating shaft 49 to rotate inside the fixed block 48, so as to change the throttling surface of the butterfly valve 47. If the pressure of the required fluid is small, the throttling surface of the butterfly valve 47 is increased, and the flow rate of the fluid inside the input pipe 2 is roughly adjusted. Then, when the fluid passes through the pressure reducing valve body 1, only more precise and simple adjustments are needed to make the pressure of the fluid when it enters the output pipe 3 consistent with the actual required pressure.
