Specific embodiment
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, a kind of water outlet section of submersible type screw pump, including a tube body 1 cylindrical, after the tube body 1
End inside is equipped with can form the interior connection screw thread 2 being threadedly coupled with the front end of submersible type screw pump, meanwhile, it is equipped in tube body 1
One when the hydraulic pressure in submersible type screw pump is zero can closed tube 1, when the hydraulic pressure in submersible type screw pump is gradually increased, pipe
The water-pressure regulating device that water-flowing amount in body 1 is also gradually increased therewith.
In the present invention, preferred water-pressure regulating device includes: that a front end is equipped with tapered slope 3, rear end is equipped with and lives
The outlet pipe 5 of plug sliding sleeve 4, piston type sliding set 4 and outlet pipe 5 are in one-piece connection, and 4 outside of piston type sliding set
Slidingtype is formed with the rear inside of tube body 1 to connect；1 rear inside of tube body, which is additionally provided with one, simultaneously can limit piston type sliding set 4
The stop collar 6 of sliding distance；
One section is in the solid left semicircle cylinder 7 of semicircle shape, and the front end of the solid left semicircle cylinder 7 is equipped with first conical surface 8；
One section is in the solid right semi-circle cylinder 9 of semicircle shape, and the front end of the solid right semi-circle cylinder 9 is equipped with second conical surface
10；
