Abstract
The invention relates to a valve with a quick coupling device, comprising a valve body assembly and a quick coupling device of an exit end of the valve body assembly. The quick coupling device comprises a coupling base, a wrench is arranged on the two sides of the coupling base and fixed with a hinged shaft, the upper end of the hinged shaft is linked with a cam which drives a interlocking part, the interlocking part is connected with a locking pin, and one end of the locking pin is matched with a lock hole of a valve rod in the valve body assembly. The device overcomes the defects of leakage of fluid medium for lack of effective safety precaution designs for quick joint transmit operation in prior art. By the design, when the control valve is not closed, the quick coupling device can not be opened, the leakage of fluid medium is precluded due to incorrect operation, thus not only protecting environment and saving energy but also avoiding the occurrence of safety accidents to a certain extent. The device has the advantages of simple and compact structure, convenient operation and use and strong reliability.
Description
Technical field
The present invention relates to a kind of valve with quick coupling device.
Background technique
The rapid abutting joint transmission operation of flowing medium generally is that the delivery pipe of band rapid pipe joint is carried fetching with the valve of band quick coupling device, like the fueling operation of aviation field to aircraft.When medium transport finishes; When the workman need pull down the rapid pipe joint delivery pipe; The phenomenon of first throttle down occurs forgetting through regular meeting, thereby flowing medium is leaked, not only cause economic loss and environmental pollution; If medium is dangerous inflammable explosive article, also can cause bigger security incident.
Summary of the invention
For the rapid abutting joint transmission operation that overcomes flowing medium in the existing technology lacks effective safety precaution design; The problem that causes flowing medium to leak easily; The present invention provides a kind of valve with quick coupling device, simple and compact for structure, easy for operation, the good reliability of the valve of this band quick coupling device.
The technical solution adopted for the present invention to solve the technical problems is: the quick coupling device that comprises valve body assembly and valve body assembly outlet end; Quick coupling device comprises connection block; The connection block both sides are provided with the spanner that is fixedly linked with hinge, the upper end interlock cam of hinge, cam drive coupling component; Coupling component and lock pin join, and the lockhole of offering on the valve rod in an end of lock pin and the valve body assembly matches.
Offer pin-and-hole on the valve body in the valve body assembly, pass pin-and-hole with lock pin that coupling component one end joins and match with lockhole, the other end of coupling component matches with limiting stopper on the valve body.
Lock pin near the diameter of lockhole one side less than diameter near coupling component one side, its smaller diameter portion outer casing spring, an end of spring lean lock pin than large-diameter portion, the other end is pressed against on the valve body.
Offer " L " v notch v groove on the cam, cam cooperates with the coupling component interlock through " L " v notch v groove.
The present invention is through above-mentioned concrete design; As yet not during closing control valve, quick coupling device can not be opened, and the flowing medium of having stopped to cause because of misoperation leaks; Not only environmental protection and energy saving; And avoided the generation of security incident to a certain extent, and have advantage simple and compact for structure, easy for operation, good reliability, can be widely used in the conveying control of Aviation Fuel and dangerous inflammable and explosive medium.
Description of drawings
Below in conjunction with accompanying drawing and embodiment detailed content of the present invention is described.
Fig. 1 is the structural representation of the present invention under valve opening state;
Fig. 2 is the structural representation of the present invention under the valve closing state;
Fig. 3 is the plan view of Fig. 2;
Fig. 4 is the A-A sectional view of Fig. 2.
Embodiment
As shown in the figure; The present invention includes the quick coupling device 14 of valve body assembly 1 and valve body assembly 1 outlet end 2, in the present embodiment, valve body assembly 1 adopts ball valve design; Quick coupling device 14 drives coupling component 3; Coupling component 3 joins with lock pin 4, and the lockhole of offering on the valve rod 5 in an end of lock pin 4 and the valve body assembly 16 matches, and offers pin-and-hole 8 on the valve body 7 in the valve body assembly 1; Pass pin-and-hole 8 with lock pin 4 that coupling component 3 one ends join and match with lockhole 6, the other end of coupling component 3 matches with limiting stopper 16 on the valve body 7.Lock pin 4 near the diameter of lockhole 6 one sides less than diameter near coupling component 3 one sides, its smaller diameter portion outer casing spring 9, an end of spring 9 lean lock pin 4 than large-diameter portion, the other end is pressed against on the valve body 7.Quick coupling device 14 comprises connection block 10, and connection block 10 both sides are provided with the spanner 12 that is fixedly linked with hinge 11, the upper end interlock cam 15 of hinge 11, and cam 15 drives coupling component 3.Offer " L " v notch v groove 13 on the cam 15, cam 15 cooperates with coupling component 3 interlocks through " L " v notch v groove 13.Under the state of valve opening, lockhole 6 and the misalignment lock pin 4 offered on the valve rod 5,4 side end faces with valve rod 5 of lock pin are relative; If misoperation this moment removes to open spanner 12, because lock pin 4 heads on the sidewall of valve rod 5, spanner 12 can not move; Interface can not unload, and has guaranteed media security.After valve closing, the lockhole 6 that offer on the valve rod 5 this moment has been aimed at lock pin 4, drives cam 15 through hinge 11 when spanner 12 rotates and rotates simultaneously; " L " v notch v groove 13 on the cam 15 promotes lock pin 4 reaches and gets into lockhole 6 through coupling component 3; Spring 9 is compressed, and at this moment, interface could normally unload; And valve rod 5 can not be rotated unlatching again by lock pin 4 lockings.When once more interface being connected, depress spanner 12 after, cam 15 is reverse to be promoted to move behind the lock pins 4 and withdraws from lockhole 6, valve could normally be opened.
