Abstract
The invention discloses a non-leakage quick joint comprising a main joint and a secondary joint, wherein the main joint and the secondary joint both comprise shells, valve openings and valve cores, the valve openings are arranged at the heads of the shells, the valve cores are correspondingly arranged at the valve openings, the shells are provided with valve core executing mechanism which are inserted into the shells to drive the valve cores, the edges of the heads of the main joint and the secondary joint are respectively provided with mutually matched clamping openings and clamping heads, and the bottoms of the clamping openings are provided with sealing pads. The non-leakage quick joint disclosed by the invention can quickly connect and separate pipes when fluid exists in the pipes and has the advantages of preventing the fluid from leaking.
Description
Technical field
The invention belongs to fluid circuit link technical field, relate to a kind of pipe joint, particularly relate to a kind of without water clock rapid pipe joint.
Background technique
In fluid piping system, need to use joint and pipeline is coupled together.Mainly there is the defect of following two aspects in existing joint: one is need special instrument could realize connecting, and two is that the easy water clock of the fluid in pipeline out when connecting.For this reason, carry out pipeline connect with existing joint, must close whole pipe-line system in advance, this brings inconvenience to the expansion of system and maintenance.
Summary of the invention
For this reason, technical problem to be solved by this invention is to provide a kind of without water clock rapid pipe joint, to overcome the deficiency that prior art exists.
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 the valve port of housing head and the corresponding spool being located at valve port position, described housing is provided with the spool actuator stretching into and drive spool in housing, the head edge of described major joint and sub-joint has the bayonet socket and dop that cooperatively interact respectively, has sealing gasket bottom described bayonet socket.
Described spool actuator is by knob, rotating disk, connecting rod and valve rod are formed, described knob is located on housing, seal ring is provided with between knob and housing, described rotating disk, connecting rod and valve rod are all positioned at housing, and the center of described rotating disk is connected to the lower end of knob, and one 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 spool.
In addition, be also fixed with guide cylinder in described housing, described valve rod is positioned at guide cylinder.The consistent of valve core movement direction can be ensured like this, thus can reliably open and closed valve port.
In the specific embodiment of the present invention, the spool of described major joint is positioned at the inner side 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.Major joint can be made so consistent with the opening direction of the valve of sub-joint, thus can ensure that fluid can flow through major joint and sub-joint swimmingly, again because major joint and sub-joint can fit together, liquid remaining in joint can be reduced so as far as possible, thus play the effect avoiding liquid drip leakage.
Adopt technique scheme, the present invention have in pipeline, to have fluid situations under can connect fast with separate lines and there is the advantage avoiding fluid water clock.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the A-A direction view of the spool actuator in Fig. 1;
In figure:
100-major joint, 101-bayonet socket, 102-sealing gasket, 200-sub-joint, 201-dop, 301-housing, 302-valve port, 303-spool, 400-spool actuator, 401-knob, 402-rotating disk, 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 the valve port 302 of housing 301 head and the corresponding spool 303 being located at valve port 302 position, the side face of housing 301 is provided with the spool actuator 400 stretching into and drive spool 303 in housing 301, the head edge of major joint 100 and sub-joint 200 has the bayonet socket 101 and dop 201 that cooperatively interact respectively, has sealing gasket 102 bottom bayonet socket 101.
In the present embodiment, the spool of major joint 100 is positioned at the inner side of major joint 100 valve port, 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 are formed.Wherein, knob 401 is located on housing 301, seal ring 405 is provided with between knob 401 and housing 301, rotating disk 402, connecting rod 403 and valve rod 404 are all 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 spool 303.Further, be also fixed with guide cylinder 406 by support 407 in housing 301, valve rod 404 is positioned at guide cylinder 406, can ensure the consistent of valve core movement direction like this, thus can reliably open and closed valve port.
Be exactly more than of the present invention without water clock rapid pipe joint, its working method is as follows:
When needing major and minor joint to connect, screw in the bayonet socket first dop of sub-joint being snapped in major joint, then by the knob on the major and minor joint of knob respectively, the spool in major and minor joint is opened, thus make pipeline unimpeded.
When needing major and minor joint to be separated, first by the knob on the major and minor joint of difference knob, the spool in major and minor joint is closed, block pipeline, and then the dop of sub-joint screws out from the bayonet socket of major joint, thus major and minor joint is separated.
By foregoing detailed description, can find out, the present invention have in pipeline, to have fluid situations under can connect fast with separate lines and there is the advantage avoiding fluid water clock.
But, those of ordinary skill in the art will be appreciated that, above embodiment is only used to the present invention is described, and be not used as limitation of the invention, as long as in spirit of the present invention, all will drop in Claims scope of the present invention the change of the above embodiment, modification.
