Description

No water clock rapid pipe joint

Technical field

The utility model belongs to fluid circuit link technical field, relates to a kind of pipe joint, relates in particular to a kind of no water clock rapid pipe joint.

Background technique

In fluid piping system, need use joint pipeline is coupled together.Mainly there is the defective of following two aspects in existing joint: the one, and need special instrument could realize connecting, the 2nd, when connecting, the easy water clock of fluid in the pipeline comes out.For this reason, carry out pipeline with existing joint and connect, must close whole pipe-line system in advance, this expansion and maintenance to system has brought inconvenience.

The model utility content

For this reason, the utility model technical problem to be solved provides a kind of no water clock rapid pipe joint, to overcome the deficiency that existing technology exists.

For solving the problems of the technologies described above, the utility model adopts following technological scheme:

A kind of no water clock rapid pipe joint; Comprise major joint and sub-joint; It is characterized in that: said major joint and sub-joint have included housing, are positioned at the valve port and the corresponding spool of being located at the valve port position of housing head, and said housing is provided with and stretches into the spool actuator that drives spool in the housing; The head edge of said major joint and sub-joint has bayonet socket and the dop that cooperatively interacts respectively, and said bayonet socket bottom has sealing gasket.

Said spool actuator is by knob, and rotating disk, connecting rod and valve rod constitute, and said knob is located on the housing; Be provided with seal ring between knob and the housing; Said rotating disk, connecting rod and valve rod all are positioned at housing, and the center of said rotating disk is connected the lower end of knob, and an end hinge of said connecting rod is at the edge of rotating disk; The other end hinge is in the rear end of valve rod, and the front end of said valve rod is fixed on the spool.

In addition, also be fixed with guide cylinder in the said housing, said valve rod is positioned at guide cylinder.The unanimity of valve core movement direction can be guaranteed like this, thereby valve port can be opened and seal reliably.

In the embodiment of the utility model, the spool of said major joint is positioned at the inboard of major joint valve port, and the spool of said sub-joint is positioned at the outside of the valve port of sub-joint, and the cross section of the spool of sub-joint is less than the valve port cross section of major joint.Like this can be so that the opening direction of the valve of major joint and sub-joint is consistent; Thereby can guarantee that fluid can flow through major joint and sub-joint swimmingly; Again since major joint and sub-joint can fit together; Can reduce liquid residual in joint so as far as possible, thereby play the effect of avoiding the liquid water clock.

Adopt technique scheme, the utlity model has in pipeline, to have and to connect fast under the fluid situations and separate pipeline and have the advantage of avoiding the fluid water clock.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is elaborated:

Fig. 1 is the structural representation of the utility model;

Fig. 2 is that the A-A of the spool actuator among Fig. 1 is to view;

Among the figure:

The 100-major joint, 101-bayonet socket, 102-sealing gasket, 200-sub-joint, 201-dop, 301-housing; The 302-valve port, 303-spool, 400-spool actuator, 401-knob, 402-rotating disk; The 403-connecting rod, 404-valve rod, 405-seal ring, 406-guide cylinder, 407-support.

Embodiment

As depicted in figs. 1 and 2, the no water clock rapid pipe joint of the utility model comprises major joint 100 and sub-joint 200.

Wherein, Major joint 100 has included housing 301 with sub-joint 200; Be positioned at the valve port 302 and the corresponding spool 303 of being located at valve port 302 positions of housing 301 heads; The side face of housing 301 is provided with and stretches into the spool actuator 400 that drives spool 303 in the housing 301, and the head edge of major joint 100 and sub-joint 200 has the bayonet socket 101 and dop 201 that cooperatively interacts respectively, and bayonet socket 101 bottoms have sealing gasket 102.

In this mode of execution, the spool of major joint 100 is positioned at the inboard of major joint 100 valve ports, and the spool of sub-joint 200 is positioned at the outside of the valve port of sub-joint 200, and the cross section of the spool of sub-joint is less than the valve port cross section of major joint.

Spool actuator 400 is by knob 401, and rotating disk 402, connecting rod 403 and valve rod 404 constitute.Wherein, Knob 401 is located on the housing 301, is provided with seal ring 405 between knob 401 and the housing 301, and rotating disk 402, connecting rod 403 and valve rod 404 all are positioned at housing 301; The center of rotating disk 402 is connected the lower end of knob 401; One end hinge of connecting rod 403 is at the edge of rotating disk 402, and the other end hinge is in the rear end of valve rod 404, and the front end of valve rod 404 is fixed on the spool 303.And, also being fixed with guide cylinder 406 in the housing 301 through support 407, valve rod 404 is positioned at guide cylinder 406, can guarantee the unanimity of valve core movement direction like this, thereby can open and seal valve port reliably.

More than be exactly the no water clock rapid pipe joint of the utility model, its working method is following:

When needing major and minor joint to connect, the dop of sub-joint is snapped in the bayonet socket of major joint screw earlier, through the knob on the major and minor joint of knob respectively the spool in the major and minor joint is opened then, thereby made pipeline unimpeded.

When needing major and minor joint to separate, through the knob on the major and minor joint of knob respectively the spool in the major and minor joint is closed earlier, the blocking-up pipeline, and then the dop of sub-joint screws out from the bayonet socket of major joint, thus make major and minor joint separate.

Through above-mentioned detailed description, can find out, the utlity model has in pipeline, to have and can connect fast under the fluid situations and separate pipeline and have the advantage of avoiding the fluid water clock.

But; Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model, as long as in the connotation scope of the utility model, all will drop in claims scope of the utility model the above embodiment's variation, modification.
