Abstract
The utility model provides a novel butterfly valve structure, which comprises a valve body, a handle, a ceramic butterfly plate, a valve shaft, a fiberglass reinforced plastic reinforced bearing, a ceramic valve seat and the like. The novel butterfly valve structure is characterized in that the handle is arranged at the upper end of the valve shaft; the valve shaft and the handle are connected through a woodruff key, and are fixed through a hexagon-headed bolt; a limiting disc is arranged at the lower end of the handle; the valve body is arranged at the lower end of the limiting disc; the limiting disc is fixedly connected with the valve body through a hexagon bolt and a hexagon nut; a fiberglass reinforced plastic reinforced shaft sleeve is additionally arranged between the valve body and the valve shaft; the ceramic valve seat is arranged in the valve body; the ceramic butterfly plate is arranged on the valve shaft on the inner side of the ceramic valve seat, and is fixedly connected with the valve shaft through taper pins; and a wearable ceramic pipe sleeve is embedded into a flow-passing surface in a cavity of the valve body. The service life of the valve can be prolonged, the safety and stability of a matched equipment running system can be improved, and maintenance cost is saved.
Description
Technical field
The utility model belongs to valve and makes the field, especially relates to a kind of novel butterfly valve structure.
Background technique
At present, the valve that generally uses receives the restriction of material, structure, can not adapt to the demand of bad working environments such as increasingly high wearing and tearing, deep-etching, is mainly reflected in the weak point in working life, reveals the stability that has seriously influenced system's operation greatly.Traditional valve is badly in need of reforming completely from aspects such as material, structure and manufacturing process.
The model utility content
The purpose of the utility model provides and has a kind ofly improved the corrosion-resistant, wear-resistant of valve and wash away; And resistance to high temperature; Prolong the working life of valve, improve Security, the stability of corollary equipment operational system, be convenient to the dismounting maintenance; Practiced thrift maintenance cost, the novel butterfly valve structure of good economy performance.
The technological scheme of the utility model is: a kind of novel butterfly valve structure, and comprise that valve body, handle, ceramic butterfly plate, valve shaft, glass fibre reinforced plastics strengthen bearing, ceramic valve seat etc., is characterized in that: the valve shaft upper end is equipped with handle; Valve shaft is connected through woodruff key with handle; Fixed by hexagon head bolt, handle, at its lower end is provided with position-arresting disk again, and the position-arresting disk lower end is provided with valve body; Position-arresting disk is fixedly connected with hexagon nut through hex head bolt with valve body; Install glass fibre reinforced plastics between valve body and the valve shaft additional and strengthen axle sleeve, be provided with ceramic valve seat in the valve body, on the inboard valve shaft of ceramic valve seat ceramic butterfly plate is installed; The pottery butterfly plate is connected through the taper pin fixed installation with valve shaft, in the valve body chamber, is installed with the ceramic wear-resisting pipe box on the flow-passing surface.
Advantage and the good effect that the utlity model has are: improved the corrosion-resistant, wear-resistant of valve and washed away, and resistance to high temperature, the working life of prolongation valve; Improve Security, the stability of corollary equipment operational system; Be convenient to the dismounting maintenance, practiced thrift maintenance cost, good economy performance.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the left side TV structure schematic representation of Fig. 1.
Among the figure:
1, valve body 2, ceramic valve seat 3, ceramic butterfly plate 4, valve shaft
5, woodruff key 6, hex head bolt 7, hexagon nut 8, position-arresting disk
9, hexagon head bolt 10, glass fibre reinforced plastics strengthen axle sleeve 11, taper pin 12, handle
13, ceramic wear-resisting pipe box
Embodiment
Preferred embodiment in the face of the utility model is elaborated down.
Like Fig. 1, shown in 2, the utility model provides a kind of novel butterfly valve structure, comprises that valve body 1, handle 12, ceramic butterfly plate 3, valve shaft 4, glass fibre reinforced plastics strengthen bearing 10, ceramic valve seat 2 etc.Valve shaft 4 upper ends are equipped with handle 12, and valve shaft 4 is connected through woodruff key 5 with handle 12, and are fixing by hexagon head bolt 9 again; Handle 12 lower ends are provided with position-arresting disk 8; Position-arresting disk 8 lower ends are provided with valve body 1, and position-arresting disk 8 is fixedly connected with hexagon nut 7 through hex head bolt 6 with valve body 1, install glass fibre reinforced plastics between valve body 1 and the valve shaft 4 additional and strengthen axle sleeve 10; Be provided with ceramic valve seat 2 in the valve body 1; On the ceramic valve seat 2 inboard valve shafts 4 ceramic butterfly plate 3 is installed, ceramic butterfly plate 3 is connected through taper pin 11 fixed installations with valve shaft 4, in valve body 1 chamber, is installed with ceramic wear-resisting pipe box 13 on the flow-passing surface.
The utility model has improved the corrosion-resistant, wear-resistant of valve and has washed away because the part parts have used high performance structure ceramic, and resistance to high temperature, has prolonged the working life of valve; Strengthen axle sleeve 10 because glass fibre reinforced plastics has been installed on the utility model valve shaft 4 again, its wearability makes it not yielding, has improved Security, the stability of corollary equipment operational system, and is convenient to the dismounting maintenance, has practiced thrift maintenance cost, good economy performance.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
