Abstract
A frequently-disassembled liquid conveying pipeline interface consists of an interface body, a valve, a spring and a pin. At the radial position of the interface, the valve passes through a valve gap on the interface body, and the tail end of the valve is connected with a pin seat on the interface body by a pin. A spring is arranged below the valve and fixed on the interface body, and a bulge is arranged on the valve. The interface body is embedded with a guard ring and is provided with a notch. The liquid conveying pipeline interface can realize axial direct connection and separation, has the advantages of rapid connection, good reliability, large connection angle, convenience and durability, and can realize connection with the existing liquid conveying pipeline interface. Is particularly suitable for fire hose joints.
Description
The utility model relates to a kind of liquid transmission pipeline interface of frequent dismounting.Specifically be meant at interface radially by flap valve is arranged, can realize axially directly joint and the liquid transmission pipeline interface that separates.
Known liquid transmission pipeline interface, the breach and the groove formation that fixing lobe and hook are arranged on interface body and insert for lobe, the joint of two interfaces will insert breach and rotation with lobe a fixing position, the hook groove is coincide realize.When being used for to curl soft pipeline like this, pass to the highly pressurised liquid separation of spinning easily, and this interface engaging process is long, engagement angles is little, engage difficulty night, poor reliability, working life are lacked.
The purpose of this utility model is: provide a kind of joint firm rapid, engagement angles is big, convenient durable liquid transmission pipeline interface.
The purpose of this utility model is achieved in that as shown in Figure 1 interface is made up of interface body (3), flap valve (4), spring (8) and Xiao (12).By the flap valve breach (15) on the interface body (3), (as shown in Figure 2) connects flap valve tail end (11) with Xiao (12) with Xiao's seat (16) of interface body (3) at radial position flap valve (4).There is spring (8) to be fixed on the interface body groove (10) under the flap valve (4), leaves projection (7) on the flap valve (4), stud with guard ring (5) on the interface body (3), but and gap (17).(as shown in Figure 3)
When two interface butt joints, flap valve inclined-plane (1) contacts with interface body inclined-plane (13), and continues to overcome relatively forward the elastic force of spring (8), and flap valve hook (2) and interface body groove (14) are coincide, and realizes the direct connection that two interfaces are axial.When hand overcomes the elastic force of spring (8) by the long inclined-plane of two flap valves (9),, make flap valve (4) radial contraction, two interfaces relatively backward, realize that two interfaces axially directly separate, the flap valve projection (7) on the flap valve (4) can strengthen coupling reliability, alleviates the shearing force of Xiao (12).Guard ring (5) on the interface body (3) can be protected interface, increases the service life.
Advantage of the present utility model and good effect are: connect rapidly, good reliability, engagement angles be big, convenient durable, and can go up gap (17) in interface body (3), so that connect with existing interface.
It is as follows that embodiment of the present utility model engages description of drawings:
Accompanying drawing 1 is the structural drawing of liquid transmission pipeline interface;
Accompanying drawing 2 is local positive views of liquid transmission pipeline interface body;
Accompanying drawing 3 is partial side views of liquid transmission pipeline interface body.
(1) in the accompanying drawing 1 is the flap valve inclined-plane, and (2) are the flap valve hooks, and (3) are interface body, and (4) are flap valves, and (5) are guard rings, and it is made by hard material.(6) be internal orifice in the interface body (3), it still uses the internal orifice of former interface.(7) be the flap valve projection, (8) are springs, and (9) are the long inclined-planes of flap valve, and (10) are the interface body grooves, and (11) are the flap valve tail ends, and (12) are Xiao.In the accompanying drawing 2, (13) are the interface body inclined-planes, and (14) are the interface body grooves, and (15) are the flap valve breach on the interface body (3), and (16) are Xiao's seats.In the accompanying drawing 3, (17) are breach.This liquid transmission pipeline interface is specially adapted to fire hose coupling.
Claims (3)
1, a kind of liquid transmission pipeline interface of frequent dismounting is characterized in that: interface by interface body (3), flap valve (4), spring (8), and Xiao (12) form.In the radial position of interface, flap valve (4) connects flap valve tail end (11) with Xiao (12) by the flap valve breach (15) on the interface body (3) with Xiao's seat (16) of interface body (3).
2, by the described liquid transmission pipeline interface of claim 1, it is characterized in that: have spring (8) to be fixed on the interface body groove (10) under the flap valve (4), stud with guard ring (5) on the interface body (3).
3, by the described liquid transmission pipeline interface of claim 2, it is characterized in that: leave projection (7) on the flap valve (4).
