Embodiment Construction

[0018] Take a section of round pipe that matches the diameter of the industrial pipeline as the inner valve pipe 18, and the pipe ports at both ends are respectively used as the input port 10 and the output port 13 of the valve. The middle section of the inner valve pipe 18 is provided with a partition 19, and the inner valve pipe 18 is divided There are two sections, respectively an input section and an output section, the output section is provided with an output valve hole 15, and the input section is provided with an input valve hole 16 and a balance hole 17, such as figure 1 , 2 shown. The inner edges of the three sealing rubber sleeves are respectively socketed in corresponding fixing grooves on the outer wall of the inner valve tube 18 . From the end of the outer valve tube 14, insert the inner cone pressure ring 1, the outer cone pressure ring 2, and the positioning pressure ring 7 with threaded buckles respectively, and assemble them in sequence, as shown in FIG. F...

Abstract

The invention relates to a valve body moving type on-off valve for industrial pipelines. The valve body moving type on-off valve is mainly used for solving quality and pollution problems caused by casting machining of present valves. The valve body moving type on-off valve comprises an outer valve pipe and an inner valve pipe. Pipe openings in the two ends of the inner valve pipe serve as an input opening and an output opening respectively and are provided with flanges respectively. The inner valve pipe is provided with a partition, the partition partitions the inner valve pipe into an input section and an output section, the output section is provided with an output valve hole, and the input section is provided with an input valve hole and a balance hole. Three sealing rubber sleeves are arranged between the inner valve pipe and the outer valve pipe, and a water inlet and outlet cavity and a balance water cavity are formed between the sealing rubber sleeves. When the outer valve pipe moves leftwards or rightwards, the valve is switched on or switched off. By the adoption of industrial pipe products, the valve body moving type on-off valve is convenient to machine, reliable in quality and stable in performance, and the problems that casting type valves are not uniform in quality, high in cost and high in pollution are eradicated. The valve body moving type on-off valve is not influenced by the pressure of a fluid medium, is switched on or switched off in a rolling mode, is small in abrasion and on-off flow resistance, large in flow and good in sealing performance and can be used in industrial pipe networks for conveying liquid or gas.

Description

technical field [0001] The invention relates to an opening and closing device for transporting gas or liquid through pipelines, in particular to a valve for industrial pipelines. Background technique [0002] In the pressure-bearing valves of industrial pipelines, due to both cost economy and design flexibility, the molding of the valve shell and the input and output ports are all cast, because the casting process is affected by size, wall thickness, climate, raw materials and Due to various factors in the construction operation, various casting defects such as blisters, pores, cracks, shrinkage porosity, shrinkage cavities and inclusions will appear in the castings, and the quality of the formed products is very unstable. Moreover, the pollution of casting to soil and atmospheric environment is very serious. The consumption of energy also ranks first in the industry, so in order to change this status quo, it is necessary to find new technical solutions and change the exist...
