Abstract
The utility model discloses a ball valve, which comprises a valve seat, wherein the valve seat is internally provided with a valve core, wherein a channel of the valve core is internally provided with a tapered hole and a tapered plug for sealing the tapered hole, the tapered hole is internally provided with a support which is provided with a guide column body, the guide column body is provided with multiple threads, the tapered plug is provided with a screwed hole matched with the guide column body, a compression spring of the support is arranged between the tapered plug and the support, and one end of the tapered plug, back to the tapered hole, is provided with spiral blades uniformly. Liquid with the pressure within the range of a set value can flow to pass through the channel of the valve core normally, when a liquid flow with pressure exceeding the set pressure value pushes the spiral blades to rotate in order to drive the tapered plug to rotate to drive the tapered plug to move towards the tapered hole under the action of the multiple threads, so that the effective area of the liquid channel is reduced, liquid is reduced, and the pressure of a subsequent pipeline is reduced. When the liquid pressure is reduced, the compression spring pushes the tapered plug to reset to drive the spiral blades to rotate reversely until the liquid pressure and liquid flow pressure are balanced, so that the fluctuation of variable pressure in the pipeline can be regulated and controlled effectively to become stable.
Description
Technical field
The utility model relates to a kind of ball valve.
Background technique
Simple, the function singleness of the ball-valve structure that is widely used at present pipeline only is used for the break-make of pilot line.Often exist pressure instability in the pipeline, damage easily pipeline component.
Summary of the invention
The defective that the utility model in use exists for solving prior art provides a kind of ball valve that comprises pipeline component that can automatically regulate hydraulic pressure of pipe line.
The technological scheme that the utility model solves existing issue is: a kind of ball valve, comprise valve seat, be provided with spool in the valve seat, as improvement, the tapered plug that is provided with taper hole in the described valve core channel and can seals this taper hole, be provided with a support in the taper hole, be provided with a guiding cylinder on the support, be provided with multiple thread on the guiding cylinder, be provided with the screw that cooperates with the cylinder that leads on the described tapered plug, standoff stage clip is set between described tapered plug and the support, and described tapered plug dorsad taper hole one end is evenly equipped with propeller blade.
As further improvement, be provided with the ladder end cap that covers taper hole on the described tapered plug.
As further improvement, described tapered plug dorsad taper hole one end is provided with an external diameter less than the ring-type cylinder of tapered plug, and described propeller blade is distributed on the cylinder.
The utility model compared with prior art, the tapered plug that taper hole is set in valve core channel and can seals the screwdriver hole, tapered plug one end is provided with propeller blade, tapered plug with multiple-threaded guiding cylinder, but the hydraulic pressure proper flow in range of set value is passed valve core channel, surpass the force value of setting, liquid stream promotes propeller blade and rotates, the rotation of drive tapered plug, under multiple-threaded effect, drive tapered plug and move to taper hole, reduce the useful area of liquid chunnel, reduce liquid stream, reduce the pressure of follow-up pipeline.When hydraulic pressure reduces, stage clip promotes tapered plug and resets, and drives the propeller blade counterrotating, until balance each other with flow stream pressure, but its beneficial effect is the fluctuation of change pressure in the Effective Regulation pipeline, makes it trend steadily.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to Fig. 1, the implementation case comprises valve seat 1, be provided with spool 2 in the valve seat 1, the tapered plug 3 that is provided with taper hole 21 in spool 2 passages and can seals this taper hole 21, be provided with a support in the taper hole 21, be provided with a guiding cylinder 4 on the support, be provided with multiple thread on the guiding cylinder 4, be provided with the screw that cooperates with the cylinder 4 that leads on the tapered plug 3, standoff stage clip 5 is set between tapered plug 3 and the support, tapered plug 3 dorsad taper hole 21 1 ends is evenly equipped with propeller blade 31, and the pressure promotion tapered plug that multiple thread is convenient to stage clip or liquid stream moves axially.
As preferably, be provided with the ladder end cap that covers taper hole on the tapered plug.
In order to improve the thrust of propeller blade 31, tapered plug 3 dorsad taper hole 21 1 ends is provided with an external diameter less than the ring-type cylinder 41 of tapered plug 3, and propeller blade 31 is distributed on the cylinder 41.
