Description
Technical field
The utility model belongs to technical field of valve manufacturing, relates to a kind of shuttle valve, particularly a kind of five-way shuttle valve.
Background technique
At present, shuttle valve is widely used in the hydraulic system, shuttle valve can connect automatically different ingress liquid medium flow to passage.Traditional shuttle valve comprises valve body, column slide core and plug, valve body in a tubular form and the valve body sidepiece offer three through holes, the column slide core is positioned at valve body, plug sealed valve body two end part.When leftmost side through hole flowed into hydraulic oil, the column slide core was pushed to the right side in the effect of hydraulic pressure like this, thus the through hole of the sealing rightmost side, and this moment, hydraulic oil can flow out from the through hole at middle part; When rightmost side through hole flowed into hydraulic oil, the column slide core was pushed to the left side in the effect of hydraulic pressure, thus the through hole of the sealing leftmost side, and this moment, hydraulic oil can flow out from the through hole at middle part.
Traditional shuttle valve adopts the column slide core, and is high to the turbidity test requirement of hydraulic oil, in case there is foreign matter in the hydraulic oil, the column slide core is easily stuck, and cisco unity malfunction exists simultaneously between column slide core and the valve body and has matching gap, cause oil leakage phenomenon, the shuttle valve reliability is bad.At these problems, people have carried out various designs to shuttle valve, and some has also applied for patent.For example, the Chinese patent literature data discloses a kind of steel ball type shuttle valve [application number: 200920171933.1 that is threaded; Notice of authorization number: CN201502746U], it comprises valve body, steel ball, joint, O shape circle, valve body is provided with left and right two nipple orifice that are used for installing usefulness, between left and right two nipple orifice, a shuttle valve sleeve is arranged, aperture above the shuttle valve sleeve has the passage that is connected with valve body, but the free rolling steel ball is positioned at shuttle valve sleeve, and the diameter of bore of joint is less than the diameter of steel ball, and an end of the sphere of steel ball and joint acute angle forms linear sealing.
Above-mentioned steel ball type shuttle valve moves the rolling that changes steel ball into the Spielpassung of original column slide core, and is lower to the turbidity test requirement of hydraulic oil, can not cause stuck phenomenon, and reliability strengthens.The left and right joint that all is equipped with of this steel ball type shuttle valve also is provided with shuttle valve sleeve between two joints, needs the component of processing many like this, the processing cost height, though be provided with O shape circle between joint and the valve body, sealing is still not ideal enough, and O shape circle to bear pressure capability bad.
Summary of the invention
The purpose of this utility model is at the above-mentioned problems in the prior art, and a kind of five-way shuttle valve of simple in structure, good airproof performance is provided.
The purpose of this utility model can realize by following technical proposal: a kind of five-way shuttle valve, comprise valve body, steel ball and stifled bolt, it is characterized in that, described valve body comprises all the first access portion and the second access portion in a tubular form, the described first access portion and the second access portion be arranged in parallel and the first access portion and the second access portion between be fixed with the joint of tubulose, the middle part of described joint side is provided with the output terminal that the pore with joint links, the pore aperture of joint is positioned at the pore of joint greater than the pore aperture of the second access portion and endoporus aperture and described steel ball, the side of the described first access portion is provided with mounting hole, described stifled bolt is positioned at mounting hole and stifled bolt is provided with and the first access portion, the endoporus that the pore of the second access portion and joint links is provided with sealing configuration between the described stifled bolt and the first access portion.
