Abstract

The utility model relates to a wearing-resistance and current saving device which belongs to the field of a throttling device of a conveying pipeline. The utility model is composed of a throttling hole plate and a fixing connecting component, wherein, the hole plate is in a concave shape with eccentric holes; the concave part is adhesively bonded with a stone casting plate which has the ability of wearing resistance with is provided with eccentric holes; the hole plate can be welded into a round pipe in a fixed type, and two ends of the round pipe are welded in the pipeline. Tow short round pipes with outward convex rings in the inner ends of both sides of the throttling plate, the sealing rings on the outer edges of the throttling plate and the convex rings of the short round pipes and a fixed connecting component formed by two omega-shaped clips can be disassembled. The wearing-resistance and current saving device has the characteristics of good wearing resistance, no deposition phenomenon, safe and realiable use, and convenient disassembly and assembly.

Description

Wear-resistance flow regulator

The utility model belongs to conveyance conduit throttling arrangement class.

For all throttling arrangement being housed in the conveyance conduit of carrying primary mixture, lime-ash slurry, ore slurry; Present throttling arrangement has fixed and detachable two kinds, all by being made up of the restricting orifice of center hole and fixed coupling unit; Fixed fixed coupling unit is a garden pipe, and restricting orifice is inserted and is pressed in the pipe of garden, and garden pipe two ends seam is on conveyance conduit; The fixed coupling unit of disassembling is that pipe two ends, a garden are welded with the flange plate that connects with conveyance conduit, and the restricting orifice seam is in the pipe of garden.The problem of above-mentioned throttling arrangement is: restricting orifice is to be made by cast iron or steel plate, wears no resistance; The hole of orifice plate easily produces depositional phenomenon, easily produces explosive accident when containing combustible substance in the mixed thing of fluid gas powder on the central position.Fixed flange connecting structure, the problem of the big demolition inconvenience of weight in addition.

The purpose of this utility model is: provide that a kind of wear resistance is good, no depositional phenomenon, safe and reliable, lightweight wear-resisting throttling arrangement.

Technical measures of the present utility model are: restricting orifice adopts the structure of spill, eccentric opening, is bonded with a glass cermaic plate that has eccentric opening in the notch of restricting orifice.

Wear-resisting throttling arrangement of the present utility model because restricting orifice is spill, eccentric opening, is bonded with the glass cermaic plate of an eccentric opening in notch, so good, the no depositional phenomenon of wear resistance, safe and reliable good effect are arranged.

Accompanying drawing is a structural representation of the present utility model.(disassembling).

Restricting orifice A adopts structure spill, eccentric opening, is bonded with the glass cermaic plate 1 of an eccentric opening in notch; Fixed fixed coupling unit adopts a garden pipe 3, and the outer periphery seam of eccentric orifice plate A is on the inwall of

garden pipe

3, and 3 two ends seam are managed in conveyance conduit in the garden.Detachable fixed coupling unit, by the inner end outer rim of eccentric orifice plate A both sides by two weak points of bulge loop outside garden pipe 3, form at the clip 2 of the seal ring 4 of the bulge loop outer rim of eccentric orifice plate A and short garden pipe 3 and two Ω shapes.The outer end seam of two short garden pipes 3 is in conveyance conduit, and two clips 2 clamp restricting orifice A, two short garden pipes 3 to connect and sealing by bolt 5 and seal ring 4.Adopt glass cermaic plate 1 obviously to improve as the fluoran stream surface wear resistance; Adopt eccentric opening can eliminate depositional phenomenon; Adopt yoke configurations than original flange plate structure.Easy accessibility, lightweight advantage are arranged.

Claims

1, a kind of wear-resisting throttling arrangement is made up of restricting orifice and fixed coupling unit; It is characterized in that:

A. restricting orifice is spill, eccentric opening;

B. in the notch of restricting orifice, be bonded with the glass cermaic plate of a band eccentric opening.

2, by the described throttling arrangement of claim 1, it is characterized in that: fixed coupling unit is a garden pipe, and the outer periphery seam of eccentric orifice plate is on the inwall of garden pipe.

3,, it is characterized in that by the described throttling arrangement of claim 1: be fixedly connected by in the inner end of eccentric orifice plate both sides by two short gardens pipes of outer bulge loop, manage in restricting orifice and short garden that the clip of the seal ring of bulge loop outer rim and two Ω shapes forms.
