Description

Without water clock rapid pipe joint

Technical field

The invention belongs to fluid circuit link technical field, relate to a kind of pipe joint, relate in particular to a kind of without water clock rapid pipe joint.

Background technique

In fluid piping system, need to 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 is out.For this reason, carry out pipeline with existing joint and connect, must close in advance whole pipe-line system, this expansion and maintenance to system has brought inconvenience.

Summary of the invention

For this reason, technical problem to be solved by this invention provides a kind of without water clock rapid pipe joint, the deficiency that exists to overcome prior art.

For solving the problems of the technologies described above, the present invention adopts following technological scheme:

A kind of without water clock rapid pipe joint, comprise major joint and sub-joint, it is characterized in that: described major joint and sub-joint have included housing, be positioned at valve port and the corresponding spool of being located at the valve port position of housing head, described housing is provided with and stretches into the spool actuator that drives spool in the housing, the head edge of described major joint and sub-joint has respectively bayonet socket and the dop that cooperatively interacts, and described bayonet socket bottom has sealing gasket.

Described spool actuator is by knob, rotating disk, connecting rod and valve rod consist of, described knob is located on the housing, be provided with seal ring between knob and the housing, described rotating disk, connecting rod and valve rod all are positioned at housing, and the center of described rotating disk is connected to the lower end of knob, and an end hinge of described 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 described valve rod is fixed on the spool.

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

In the specific embodiment of the present invention, the spool of described major joint is positioned at the inboard of major joint valve port, and the spool of described 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 be 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 like this residual in joint of liquid as far as possible, thereby play the effect of avoiding liquid drip leakage.

Adopting technique scheme, the present invention to have advantages of to have in pipeline can connect fast under the fluid situations and separate pipeline and have the fluid of avoiding water clock.

Description of drawings

The present invention is described in detail below in conjunction with the drawings and specific embodiments:

Fig. 1 is structural representation of the present invention;

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, of the present invention without water clock rapid pipe joint, comprise major joint 100 and sub-joint 200.

Wherein, major joint 100 and sub-joint 200 have included housing 301, be positioned at 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 the spool actuator 400 that stretches into housing 301 interior driving spools 303, the head edge of major joint 100 and sub-joint 200 has respectively bayonet socket 101 and the dop 201 that cooperatively interacts, and bayonet socket 101 bottoms have sealing gasket 102.

In the present embodiment, 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 consist of.Wherein, knob 401 is located on the housing 301, be provided with seal ring 405 between knob 401 and the housing 301, rotating disk 402, connecting rod 403 and valve rod 404 all are positioned at housing 301, the center of rotating disk 402 is connected to 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 by support 407 in the housing 301, valve rod 404 is positioned at guide cylinder 406, can guarantee like this consistent of valve core movement direction, thereby can open reliably and seal valve port.

More than be exactly of the present invention without water clock rapid pipe joint, its working method is as follows:

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

When needing major and minor joint to separate, by the knob on the major and minor joint of knob respectively the spool in the major and minor joint is closed first, blocking-up pipeline, and then the dop of sub-joint screws out from the bayonet socket of major joint, thereby so that major and minor joint separate.

By foregoing detailed description, can find out, the present invention has advantages of to have in pipeline and can connect fast under the fluid situations and separate pipeline and have the fluid of avoiding water clock.

But, those of ordinary skill in the art will be appreciated that, above embodiment illustrates the present invention, and be not to be used as limitation of the invention, as long as in connotation scope of the present invention, all will drop in claims scope of the present invention the above embodiment's variation, modification.
