Abstract
The invention discloses a simple adjustable pressure-reducing valve which comprises a valve body, a valve core and a transmission shaft for adjusting the valve core to move front and back, wherein a valve cavity and a water inlet channel and a water outlet channel which are communicated with the valve cavity and lead high water pressure to enter, the valve cavity is the conical valve cavity, a pressure-adjusting core rod which is convexly arranged in the water inlet channel is arranged at the top end of the valve core, a baffle plate which is protrudent out of the surface is further arranged on the circumference of the valve core, and a plurality of slopes which can adjust the intervals with the inner wall of the valve cavity during front and back movement are arranged on the outer side of the baffle plate. The invention aims at providing the simple adjustable pressure-reducing valve with small volume, convenient use, easy operation and adjustable outlet pressure.
Description
[technical field]
The present invention relates to a kind of reduction valve.
[background technique]
Existing reduction valve is shaped on the cartridge type valve body two-port load upper flap respectively of bulge loop and the valve chest that The lower flap is formed by interior waist; Valve core is by the T shape piston of hollow; Be shaped on several through holes that are uniformly distributed with, outer wall suitable for reading on the perisporium of piston bottom side and be shaped on edge seal ring in the annular groove, the piston type valve core that the piston bottom end face is made up of pressing plate and backing plate folder company sealing gasket, valve core load movingly is in valve casing. this type structure of relief pressure valve complicacy; Fabricating cost is high, and is also not too convenient in the use.
[summary of the invention]
Problem to be solved by this invention provides the simple adjustable pressure-reducing valve of little, easy to use, the easy-operating can regulate outlet pressure of a kind of volume.
In order to solve the problem of above-mentioned existence, the present invention has adopted following technical proposal:
A kind of simple adjustable pressure-reducing valve; Comprise valve body, spool and be used for the forward and backward mobile transmission shaft of regulating spool; Intake tunnel and exhalant canal that the high hydraulic pressure of the confession that is provided with valve pocket in the valve body and is communicated with valve pocket gets into is characterized in that said valve pocket is the taper valve pocket, and said spool top is provided with the pressure regulation core bar of salient mounting in said intake tunnel; The spool circumference also is provided with protruding baffle plate in the surface, and the baffle plate outside is provided with forward and backward a plurality of inclined-planes at interval between can regulate and valve pocket inwall when mobile;
A kind of as stated simple adjustable pressure-reducing valve; It is characterized in that said intake tunnel outlet faces the taper valve pocket vertex of a cone; The said exhalant canal mouth of pipe is positioned at taper valve pocket awl body, the pressure regulation bar of said pressure regulation core bar for increasing successively to butt direction external diameter along its top;
A kind of as stated simple adjustable pressure-reducing valve; It is characterized in that said valve body is provided with the sliding chamber that is communicated with valve pocket; Said valve core housing is contained in forward and backward slip in the sliding chamber; Also be provided with a plurality of seal rings between spool and the sliding cavity wall, the spool circumference offers a plurality of annular grooves, and each seal ring correspondence is sleeved in each annular groove;
A kind of as stated simple adjustable pressure-reducing valve is characterized in that said spool is screwed in said transmission shaft and stretches into the end in the valve body, and transmission shaft stretches into a end in the valve body and is provided with and is used for the forward and backward mobile screw thread of regulating spool.
The invention has the beneficial effects as follows: reduction valve comprises valve body, spool and is used for the forward and backward mobile transmission shaft of regulating spool; Be provided with valve pocket in the valve body, valve pocket is the taper valve pocket, and the spool top is provided with the pressure regulation core bar of salient mounting in intake tunnel; The spool circumference also is provided with protruding baffle plate in the surface; The baffle plate outside is provided with forward and backward at interval inclined-plane between can regulate and valve pocket inwall when mobile, and high hydraulic pressure gets in the reduction valve valve pocket through intake tunnel during use, drives through rotating drive shaft that spool is forward and backward to be moved to regulate interval between inclined-plane and the valve pocket inwall of length and spool circumference baffle plate that the pressure regulation core bar inserts intake tunnel; Completion is to the increase and decrease control through exhalant canal flow rate of water flow, flow; Reach adjusting to the control of exhalant canal water outlet hydraulic pressure, volume is little, overall structure is simple, and is easy for operation.
