Abstract
The utility model relates to a hydraulic two-way rapid joint which mainly comprises a left valve body, a right valve body and a rapid connecting assembly, wherein a left nonreturn valve is arranged in the left valve body, and a right nonreturn valve is arranged in the right valve body. The left nonreturn valve is composed of the left valve body, a left valve rod, a spring of the left valve rod and a spring seat, and the right nonreturn valve is composed of the right valve body, a right valve core, a spring of the right valve core and an oil outlet nut. A circular seal pad is arranged on the contact surface of the left valve body and the right valve body in the right valve body, and rectangular sealing rings which can be used for sealing a conical part of the valve body are respectively arranged at the rear parts of conical surfaces of the valve rods of the left nonreturn valve and the right nonreturn valve. The utility model has the advantage that because the two valve bodies are sealed in a plane mode by the seal pad, the problem of the existing poor sealing can be overcome. The sealing is reliable after the joint is switched on. Simultaneously, because the rear parts of the left conical nonreturn valve and the right conical nonreturn valve are sealed by the rectangular sealing rings, the sealing effect of the conical valve is enhanced. When the left valve body and the right valve body are separated, the two nonreturn valves are reliably sealed, and the phenomenon of oil leakage can not occur.
Description
Affiliated technical field
The utility model relates to hydraulic element, specifically refers to a kind of bidirectional hydraulic joint.
Background technique
Hydraulic bidirectional rapid pipe joint is a kind ofly need not use any instrument, the hydraulic pipe line joint that can load onto rapidly or unload just, and being applicable to needs the often hydraulic plumbing system of mounting or dismounting, as all kinds of oil pumps, all kinds of hydraulic tools etc.In the prior art, hydraulic bidirectional rapid pipe joint is generally by left and right valve body, left and right spool, and connecting sleeve and one group of locking ball are formed, and left and right valve body and left and right spool constitute left and right one-way valve.Only need pass through connecting sleeve during use, the locking ball group is pressed in the V-shaped groove on another valve body, make left and right valve body combination, at this moment,,, make the oil circuit connection with left and right two one-way valve opens because left and right spool offsets.But oil leakage phenomenon takes place in joint and left and right sides one-way valve that existing hydraulic bidirectional rapid pipe joint is generally all adopted O shape to enclose to seal right valve barrel easily.
Summary of the invention
The purpose of this utility model is to propose a kind of hydraulic bidirectional rapid pipe joint of adopting the sealing gasket sealing between two one-way valves, connects the back poor sealing to overcome the prior art middle joint, causes the defective of leakage of oil.
Another purpose of the present utility model is to adopt at the rear portion of the conical valve of left and right two one-way valves the rectangular seal sealing, with the defective of the poor sealing that overcomes left and right two one-way valves.
A kind of hydraulic bidirectional rapid pipe joint of the present utility model, mainly comprise a left valve barrel 2 and a right valve barrel 7, wherein left valve barrel 2 is spirally connected with left connector 1, right valve barrel 7 is spirally connected with right connector 8, be provided with the left one-way valve of forming by left spool and left valve barrel 2 in the left valve barrel 2, be provided with the right one-way valve of forming by right spool 6 and right valve barrel 7 in the right valve barrel 7, on left valve barrel 2 or right valve barrel 7, be provided with by connecting sleeve 4, the quick connection assembly that connecting sleeve spring 12 and locking ball 5 are formed, described left one-way valve is by left valve barrel 2, left side valve rod 3, left side valve rod spring 10, spring seat 9 is formed, and the conical surface 3a on the left valve rod 3 and the tapered portion 2a of left valve barrel coincide, described right one-way valve is by right valve barrel 7, right spool 6, right valve core spring 16 is formed with fuel-displaced nut 15, the conical surface 6a on the same right valve rod 6 and the tapered portion 7a of right valve barrel coincide, and in described right valve barrel 7, a left side, surface of contact between the right valve barrel is provided with L shaped sealing gasket 13.
Respectively be provided with the rectangular seal 11,14 that to assist closed valve tapered portion 2a, 7a at conical surface 3a, the 6a rear portion of left and right two one-way valve valve rods 3,6.
Advantage of the present utility model is, owing to adopt the sealing gasket plane sealing between two valve bodies, has overcome the defective of poor sealing of the prior art, and it is reliable that joint is connected the back sealing; Owing to adopt the rectangular seal sealing, strengthened the sealing effect of mitre velve simultaneously, so when left and right valve body separated, two one-way valve sealings were reliable, no longer include oil leakage phenomenon at cone shaped one-way valve rear portion, the left and right sides.
