Abstract
The utility model relates to a valve with quick coupling device, which comprises a valve body assembly and a quick coupling device on the outlet end of the valve body assembly, a linking part which is linked with the opening and closing action of the quick coupling device in the quick coupling device is connected with a locking pin, one end of the locking pin is matched with a locking hole which is arranged on a middle valve rod of the valve body assembly, a pin hole is arranged on a valve body in the valve body assembly, the locking pin which is connected with the linking part penetrates through the pin hole and is matched with the locking hole, and the other end of the linking part is matched with a limiting block on the valve body. The device overcomes the defect that the quick butt-jointing transmitting operation of fluid media in the prior art locks the safety precaution design, and the fluid media easily leak, through the design, the quick coupling device can not be opened when a control valve is not closed, which prevents the leaking of fluid media caused by mistaken operation, the device not only protects environment and saves energy, but also prevents the generation of safety accidents in a certain degree, and has the advantages of simple and compact structure, convenient operation and use, and strong reliability.
Description
Technical field
The utility model 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, as 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 that occurs forgetting first throttle down 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 prior art lacks effective safety precaution design, the problem that causes flowing medium to leak easily, the utility model 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 technological scheme that its technical problem that solves the utility model adopts is: the quick coupling device that comprises valve body assembly and valve body assembly outlet end, in the quick coupling device with its on-off action interlock coupling component and lock pin join, 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 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.
Quick coupling device comprises connection block, and the connection block both sides are provided with the spanner that is fixedly linked with hinge, the upper end interlock cam of hinge, and cam matches with coupling component.
Offer " L " v notch v groove on the cam, cam cooperates with the coupling component interlock by " L " v notch v groove.
The utility model is by above-mentioned specific design, as yet not during closing control valve, quick coupling device can not be opened, 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 drawings and Examples detailed content of the present utility model is described.
Fig. 1 is the structural representation of the utility model under valve opening state;
Fig. 2 is the structural representation of the utility model 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 utility model comprises 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, in the quick coupling device 14 with its on-off action interlock coupling component 3 join with lock pin 4, the lockhole of offering on the valve rod 5 in one end of lock pin 4 and the valve body assembly 16 matches, offer 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 joins 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 matches with coupling component 3.Offer " L " v notch v groove 13 on the cam 15, cam 15 cooperates with coupling component 3 interlocks by " 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, driving cam 15 by hinge 11 when spanner 12 rotates rotates simultaneously, " L " v notch v groove 13 on the cam 15 promotes lock pin 4 reaches and enters lockhole 6 by coupling component 3, spring 9 is compressed, and at this moment, interface could normally unload, and valve rod 5 locked by lock pin 4, can not rotate unlatching again.When once more interface being connected, depress spanner 12 after, cam 15 oppositely promotes to move behind the lock pins 4 and withdraws from lockhole 6, valve could normally be opened.
