For realizing above-mentioned purpose, the utility model adopts as follows
Technological scheme:
The described pressure regulation cone valve of the utility model pressure regulator valve group; The back guiding Taper Pipe, the back pipe that comprise the preceding pipe that connects successively, preceding guide pipe, pressure regulation cone valve, cone barrel type shape; Wherein on preceding pipe, connect at least two preceding guide pipes; And the equidistant circumference uniform distribution in guide pipe preceding pipeline center, edge before said; The other end flange of each preceding guide pipe is connected with a pressure regulation cone valve, the Taper Pipe that leads after the other end flange of each pressure regulation cone valve is connected with, and lead and manage upward after Taper Pipe is connected and the equidistant circumference uniform distribution in pipeline center behind the edge in described each back; Said pressure regulation cone valve comprises housing, guide cylinder, flap, valve rod and valve seat, and guide cylinder is arranged in the housing, and guide cylinder is connected by the gusset that is uniformly distributed with housing; Flap is set in the guide cylinder; Seal ring is housed on the flap, and valve rod is connected on the flap, is provided with guide plate near export department in the housing; Valve seat is housed on the guide plate, between flap and valve seat, is provided with the sealing surface that cooperatively interacts; Guide cylinder one end that is positioned at the housing inlet place is equipped with conical head, and conical head is provided with stuffing box, and filler, axle sleeve are housed in the stuffing box, and valve rod passes stuffing box; On conical head, be fixed with support, the stent support transmission shaft, rocking bar is connected with transmission shaft, and rocking bar is connected with connecting rod, and connecting rod is connected with valve rod, and transmission shaft is driven by drive unit.
Tapering of its awl tube of the said back guiding Taper Pipe of the utility model is 3-6 °, the length of awl tube for the 5-8 of awl tube small end nominal diameter doubly.
Its beneficial effect of the described pressure regulation cone valve of the utility model pressure regulator valve group is:
The utility model is to prior art problems; Start with from the structure of pressure regulator valve group internal influence gas flow; Through changing fluid channel structure to reduce high velocity air turbulization, turbulent flow; Reduce vibration and noise, thereby solve the problem that causes pressure regulator valve group and pipe-line system to be destroyed by vibrating and washing away.
Through moving forward and backward of flap in the pressure regulation cone valve, the airflow area is to reach the pressure regulation purpose between change flap and the valve seat.In the pressure regulation process because high velocity air is level and smooth evenly mobile along circumference with the annulus a fluid stream during through the pressure regulation cone valve; So effectively reduced the generation of turbulent flow, low-frequency vibration and very noisy; Reduce the direct erosive wear of air-flow to valve body; Improved environment, prolonged the working life of pressure regulator valve group greatly, economic benefit and social benefit are very obvious.
