Abstract
The utility model discloses a kind of loose joint ball valve of integrative-structure, comprise the ball valve with switch, ball valve one end is provided with the nut of integrally casting, the other end is provided with loose joint, described loose joint comprises the trip segment with ball valve integrative-structure, trip segment outer end is provided with flange, and the trip segment periphery cover between flange and ball valve has traveling nut; It is arc section between 30 to 60 degree that described flange comprises two symmetrical arc angles.The utility model is by the trip segment of integrative-structure, and two symmetrical arc angles are that arc section structure between 30 to 60 degree realizes traveling nut in rotary manner on flange, trip segment is entered by the space between two Symmetrical Circular Arc sections, its latter two Symmetrical Circular Arc section act as the limit stoper of traveling nut axis, reaches the technical purpose of traveling nut loose joint.
Description
Technical field
The utility model relates to a kind of ball valve, specifically a kind of loose joint ball valve of integrative-structure.
Background technique
Widely used ball valve in house ornamentation, pipeline connecting device, all requires that it possesses good switching performance at present.Ball valve with loose joint have received very large welcome due to easy to use.Loose joint is made up of malleable cast iron, also claims oil to appoint, the one of pipe fitting, profile is three-dimensional polygonal design, and internal layer is carved with three-dimensional screw thread, and Connecting format is that a permanent joint and a female joint alive support the use, two ends and respective tube threaded engagement, middle with PVC pad or rubber seal.The mode be namely threaded connection with the ball valve of loose joint connects ball valve, and makes nut movable.This structure its there is thread connecting mode all the time and carry out mounting nuts, also just unavoidablely add a leak point.How traveling nut to be installed to obtain the ball-valve structure of less leak point by the mode of one, also just to become the object of those skilled in the art's research.
Summary of the invention
The utility model provides the loose joint ball valve of the integrative-structure that a kind of structure is simple, easy to use, leak point is few.
A kind of loose joint ball valve of integrative-structure, comprise the ball valve with switch, ball valve one end is provided with the nut of integrally casting, the other end is provided with loose joint, described loose joint comprises the trip segment with ball valve integrative-structure, trip segment outer end is provided with flange, and the trip segment periphery cover between flange and ball valve has traveling nut; It is arc section between 30 to 60 degree that described flange comprises two symmetrical arc angles.The loose joint ball valve of this kind of integrative-structure due to trip segment and flange be all with ball valve integrative-structure avoid traditional thread connecting mode, decrease a leak point and improve safety in utilization.On flange, two symmetrical arc angles are that arc section structure between 30 to 60 degree realizes traveling nut in rotary manner, trip segment is entered by the space between two Symmetrical Circular Arc sections, its latter two Symmetrical Circular Arc section act as the limit stoper of traveling nut axis, reaches the technical purpose of traveling nut loose joint.
Be provided with annulus between described trip segment outer end and two arc sections of flange, the diameter of annulus is identical with the aperture of traveling nut endoporus, prevents traveling nut from skidding off from the space between two arc sections due to unexpected, and the normal use of impact.
Described arc section two ends are provided with clockwise inclined-plane, are being fit into the spiral angle in trip segment process to suit traveling nut endoporus.
The utility model is by the trip segment of integrative-structure, and two symmetrical arc angles are that arc section structure between 30 to 60 degree realizes traveling nut in rotary manner on flange, trip segment is entered by the space between two Symmetrical Circular Arc sections, its latter two Symmetrical Circular Arc section act as the limit stoper of traveling nut axis, reaches the technical purpose of traveling nut loose joint.
Accompanying drawing explanation
The loose joint ball valve being illustrated in figure 1 the utility model dress integrative-structure does not install the perspective view under traveling nut state;
Be illustrated in figure 2 the loose joint ball valve perspective view of the utility model dress integrative-structure.
Embodiment
A kind of loose joint ball valve of integrative-structure as shown in Figure 1, 2, comprise the ball valve 1 with switch 3, ball valve 1 one end is provided with the nut 2 of integrally casting, the other end is provided with loose joint, loose joint comprises the trip segment 4 with ball valve integrative-structure, trip segment 4 outer end is provided with flange 5, and the trip segment periphery between flange 5 and ball valve is overlapped and had traveling nut 6.
It is arc section between 30 to 60 degree that flange 5 comprises two symmetrical arc angles.Be provided with annulus as between preferred structure trip segment 4 outer end and two arc sections of flange 5, the diameter of annulus is identical with the aperture of traveling nut 6 endoporus.
Install for the ease of traveling nut 6 and screw in trip segment 4, arc section two ends are provided with clockwise inclined-plane.
