Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.
As shown in fig. 1 and 2, the present invention provides a fluid pressure regulating apparatus which can achieve remote regulation of fluid pressure and can improve installation and maintenance efficiency of the apparatus. Specifically, the method comprises the following steps:
the device comprises a main body control part 1, a transmission spool 2 and a transmission motor 3, wherein the main body control part 1 is connected to one end of the transmission spool 2 through a first connecting component 4, and the transmission spool 2 is of a flexible structure. Drive motor 3 passes through second coupling assembling 5 to be connected at the other end of drive spool 2, second coupling assembling 5 is the rotatory axle sleeve between drive spool 2 and drive motor 3 is connected respectively for both ends. The transmission motor 3 adjusts the flow controlled by the main control part 1 through the transmission spool 2. The drive motor 3 may also be equipped with an encoder for detecting the rotation angle of the threaded adjusting shaft 102.
The main control part 1 comprises a control component 101 and a threaded adjusting shaft 102 rotatably connected to the control component 101, a pressure reducing valve (not shown in the figure) is arranged in the control component 101, one end of the threaded adjusting shaft 102 acts on a diaphragm of the pressure reducing valve, and the other end of the threaded adjusting shaft is connected with the first connecting component 4.
As is known, the control assembly 101 is a known structure of a fluid pressure regulating device, and the threaded adjustment shaft 102 is also a conventional structure provided with the control assembly 101.
The first connecting assembly 4 comprises a connecting sleeve 401, a universal joint 402 and an adjusting nut 403, the adjusting nut 403 is sleeved at the lower end of the threaded adjusting shaft 102, the connecting sleeve 401 is sleeved at the outer side of the adjusting nut 403, the connecting sleeve 401 and the adjusting nut 403 are locked through a locking assembly, the universal joint 402 is connected at the lower end of the connecting sleeve 401, and the other end of the universal joint 402 is connected to the transmission spool 2. Specifically, the method comprises the following steps:
the locking assembly comprises a locking nut 405 and a pressing sheet 406 fixedly arranged at the tail end of the locking nut 405, the sleeve wall of the connecting sleeve 401 is provided with a threaded hole for matching the locking nut 405, and the pressing sheet 406 is positioned inside the connecting sleeve 401 and can be contacted with one prismatic side wall of the adjusting nut 403.
The working principle of the device is as follows:
during installation, the connecting sleeve 401 is sleeved on the adjusting nut 403 connected with the lower end of the threaded adjusting shaft 102 of the control assembly 101, and the locking nut 405 is screwed tightly, so that the pressing sheet 406 at the tail end of the locking nut 405 is pressed on one side wall of the prism of the adjusting nut 403. Although a gap is left between the adjusting nut 403 and the connecting sleeve 401, a fixed connection between the adjusting nut 403 and the connecting sleeve 401 is actually achieved due to the limiting effect of the pressing sheet 406 on the side wall of the adjusting nut 403. So that the control unit 101 can be freely combined with other driving units without modifying the size of the connection portion of the lower end of the control unit 101 and without affecting the fluid pressure adjusting accuracy of the apparatus.
