Description
Technical field
The utility model belongs to PPR ball valve technical fields, more particularly to a kind of valve being easy for installation and maintenance.
Background technology
Ball valve is the control unit in fluid delivery system, is generally mounted between the pipeline of fluid delivery system,
Pipeline is cut in the position that pipeline needs to install PPR ball valves during installation, then the water inlet end of ball valve both sides and water outlet are all logical
Cross loose joint structure with pipeline to be connected, PPR articulations that the loose joint structures of PPR ball valves includes mutually being welded and fixed with pipeline, by PPR
The clamp nut that articulation is fastenedly connected with valve body.Existing structure PPR ball valves are that opposite twist-on is consolidated between the two with PPR articulations
Fixed, during installation, pipeline cutting is divided into two first, pipeline reserves installation PPR ball valves and articulation with pipeline
Distance, if the stabilization between the excessive both ends that will directly affect PPR ball valves of mounting distance that reserve of cutting and pipeline connection
Property and leakproofness, or even cause connection can not be installed between pipeline and PPR ball valves apart from excessive（That is the water inlet end of PPR ball valves passes through
After PPR articulations are connected with pipeline, and other end PPR articulations and pipeline are welded, but because pipeline cutting retention away from
Cause PPR articulations can not be connected with the water outlet of PPR ball valves from excessive）；Furthermore PPR ball valves need to apply during opening and closing
Power twist-on PPR ball valves handle and achieve the goal, long-time service open and close PPR ball valves keying twist-on power can make PPR articulations with pipe
Shake between road, so that occurring situation about leaking between the two, the pipe that will be connected with PPR articulations is needed when at this moment repairing
After road cuts away pervious weld part, then pipeline and PPR articulations are welded and fixed again, but managed after cutting again
Distance between road and pipeline will bigger lead to not install, so matched PPR articulations will be replaced, if it cannot be guaranteed that
Corresponding PPR articulations are found in time, and may result in maintenance work can not carry out, and influence to use, not only troublesome and maintenance
Cost just improves.
The content of the invention
The technical problem to be solved by the present invention is to provide a kind of valve being easy for installation and maintenance, PPR can be made to live

Offered respectively on the water outlet and the corresponding end faces of clamp nut II and the matched ring packing of O-ring seals
Groove I, annular seal groove II.
The thickness of the ring type seal is equal with the thickness of fan-shaped support cap, and ring type seal uses AU/EU（Polyurethane
Rubber）Material.
The diameter of the slide preventing section is less than the aperture of screw hole and more than the aperture of slide opening.
The beneficial effects of the utility model are：
Compared with prior art, using the PPR ball valves of the utility model structure under the action of mandril and bolt, can with when
Movement, therefore the locating distance reserved either between pipeline when installing PPR ball valves and cutting are realized in PPR articulations in water outlet
During from cutting welding maintenance when being leaked between excessive or PPR articulations and pipeline again, it can be lived by adjusting PPR
Connector moves in the water outlet of PPR ball valves, so as to ensure that PPR ball valves are connected with pipeline better seal, does not have to load thus
Anxious distance excessive the problem of causing not installing between PPR ball valves and pipeline cut, also avoid welding maintenance cutting pipe again
The problem of PPR articulations are needed replacing behind road, reduces installation trouble.
