Abstract
The utility model discloses a ball valve for a long-distance pipeline, which aims at overcoming the shortcomings that an existing ball valve for the long-distance pipeline static is inconvenient to install and easily causes static accumulation. An upper supporting body is fixedly installed at the upper end of a valve body, and a lower supporting base is fixedly installed at the lower end of the valve body. A small-top and big-bottom cone arranged at the lower end of a valve rod is installed in a conical hole arranged at the upper end of a valve ball, and the valve ball is fixedly connected with the valve rod in welded mode. A spring is installed in a cylindrical hole arranged on the upper end face of a cylinder of the lower supporting base, and a steel ball is installed in the groove arranged above the spring and at the lower end of the valve ball. The ball valve for the long-distance pipeline has the advantages of being simple and reasonable in structure, convenient to install, reliable in performance and easy in massive production.
Description
Technical field
The utility model relates to a kind of ball valve, especially relates to a kind of long-distance transport pipes ball valve, is mainly used in the equipment of long oil and gas pipeline and line transportation.
Background technique
The long-distance transport pipes ball valve mainly comprises valve body, valve ball, valve rod, goes up support, following supporting base etc., and the valve ball lower end of ball valve is sitting in down on the supporting base, and the cylindrical body of following supporting base upper end cooperates with the endoporus of valve ball lower end; The valve ball upper end is fixedly connected with valve rod, and the valve rod upper end portion is arranged in the support endoporus; Rotation valve rod drives valve ball and rotates, and realizes the opening and closing of ball valve.
The valve rod of existing long-distance transport pipes ball valve is connected the employing interference fit with valve ball, will be installed in through the valve rod of liquid nitrogen frozen in the endoporus of valve ball upper end, and then weld fixing.Because the valve ball volume is bigger, quality is heavy, is not easy to assembling.
Cooperate through cylindrical body and end face thereof between the following supporting base of ball valve and the valve ball, area of contact is big between the end face, causes accumulation of static electricity, easily initiation fire.
The model utility content
For the valve rod that overcomes existing long-distance transport pipes ball valve existence is connected complex process, is not easy to install with valve ball, be prone to cause the deficiency of accumulation of static electricity between following supporting base and the valve ball, the utility model provides a kind of long-distance transport pipes ball valve of new structure.
The utility model solves the technological scheme that its technical problem adopted: the long-distance transport pipes ball valve comprises valve body, valve ball, valve rod, last support, following supporting base, and last support is fixedly mounted on the valve body upper end, and following supporting base is fixedly mounted on the lower end of valve body; The valve ball upper end is fixedly connected with valve rod, and the valve rod upper end portion is positioned at valve body and last support; The valve ball lower end is sitting in down on the supporting base, and the cylindrical body of following supporting base upper end is arranged in the endoporus of valve ball lower end.The up-small and down-big cone of valve rod lower end is installed in the taper hole of valve ball upper end, and valve ball is fixedly connected with the valve rod welding.In the cylindrical hole of following supporting base cylindrical body upper-end surface spring is installed, in the groove of spring top and valve ball lower end steel ball is installed.
The beneficial effect of the utility model is designs simplification, reasonable; Valve rod adopts cone to be connected with valve ball, is convenient to install; Effectively reduce the ball valve accumulation of static electricity, make the ball valve reliable performance; Be easy to produce in batches.
Description of drawings
Fig. 1 is the utility model long-distance transport pipes ball-valve structure schematic representation.
Among the figure: 1. transition body, 2. valve ball, 3. main body, 4. valve rod, 5. steel ball, 6. spring 7. descends supporting base, 8. goes up support.
Embodiment
The utility model is described further with embodiment below in conjunction with accompanying drawing 1.But what those skilled in the art should know is to the invention is not restricted to listed embodiment, as long as spirit according to the invention all should be included in protection scope of the present invention.
The utility model long-distance transport pipes ball valve comprises valve body, valve ball 2, valve rod 4, last support 8, following supporting base 7; Valve body comprises main body 3, transition body 1; Main body 3 is a cylindrical shape, and transition body 1 is positioned at the two ends of main body 3, and an end of transition body 1 is shaped as circular arc; The Outside diameter size is identical with main body 3 diameter dimensions, and welds with main body 3 ends; The other end that transition body 1 is extended by arc transition is a cylindrical shape, and columnar diameter dimension is identical with the long-distance transport pipes diameter, and welds with long-distance transport pipes.
The last support 8 of the utility model long-distance transport pipes ball valve is fixedly mounted on valve body main body 3 upper ends, and following supporting base 7 is fixedly mounted on the lower end of valve body main body 3, last support 8, the axis of valve body main body 3 and the axis normal of main body 3.Valve ball 2 upper ends are fixedly connected with valve rod 4, and valve rod 4 upper end portions are positioned at main body 3 and last support 8.Valve rod 4 lower ends are up-small and down-big cone, and the cone of valve rod 4 is installed in the taper hole of valve ball 2 upper ends, and valve ball 2 is fixedly connected by welding with valve rod 4.Valve rod 4 adopts cone to cooperate installation with valve ball 2, simplifies assembly technology, is convenient to assembling.
The utility model also is applicable to the multi-form used ball valves of long-distance transport pipes such as ball type, barrel-type, short cartridge type.
It should be noted that the foregoing description is example and unrestricted the present invention, those skilled in the art can design a lot of alternate embodiments and not break away from the claim scope of this patent.
