Description

High-grade general extraction liquid-injection valve

The utility model relates to the push shifter liquid-filling valve that a kind of colliery high-grade conventional mining is used.

The YQ-100A type push shifter that high-grade common coal mining face uses, the fluid injection mode that adopt in present national colliery is pumping plant and supplies with highly pressurised liquid, the reversal valve of push shifter is formed the complicated feed flow networking of a cover by high pressure feed flow pipeline, low pressure liquid back pipe road, because damaging easily, pipeline needs often to change, make the push shifter cisco unity malfunction have a strong impact on production, and pipeline is expensive big, this feed liquid way once can only push away a push shifter, complicated operation, the production needs that are far from suitable current.

In order to make colliery high-grade conventional mining push shifter fluid injection simplified control, save pipeline, and design the novel liquid-filling valve of a cover.

Colliery high-grade conventional mining liquid-filling valve is made up of valve pocket 1, one way valve 2, joint 3.

Valve pocket 1 is the hollow circular cylinder of an external diameter 45-50 millimeter, high 50-60 millimeter, open the rectangular channel of a dark 3-5 millimeter, wide 10-15 millimeter at the bottom of the post on the cylindrical at 30-35 millimeter place, overside limit height is the 8-12 millimeter, and the big hole of an interior circular diameter 30-35 millimeter is opened in the post baseplane.

One way valve 2 is made up of spacing pad 4, valve seat 5, steel ball 6, gland nut 7, valve body 8, sealing mat 9, and spacing pad 4 is that an outside diameter is the T-shaped planchet of 12-15 millimeter, thick 1-2 millimeter, hollow diameters 3-5 millimeter, thick 2-3 millimeter; Valve seat 5 is rubber cylinders of an external diameter 13-15 millimeter, thick 4-6 millimeter, diameter of bore 4-6 millimeter; Steel ball 6 diameters are the 7-9 millimeter; Gland nut 7 is hollow circular cylinders, external diameter 15-17 millimeter, thick 6-8 millimeter; One end has wide 2-3 millimeter, the in-line groove of dark 4-5 millimeter, and it is the circular hole of 6-8 millimeter, thick 2-3 millimeter that this end has diameter of bore, this circular hole the inside is the big hole of diameter 8-12 millimeter to the top; Valve body 8 is T-shaped hollow circular cylinders, big end outside diameter is 28-32 millimeter, thick 7-9 millimeter, large end face has diameter and is the 26-28 millimeter, is the big hole of 3-5 millimeter deeply, often opening a diameter in the body at big hole is the 15-17 millimeter, height is the hole of 15-17 millimeter, and hole wall has screw thread; Sealing mat 9 is that an outside diameter is that 25-30 millimeter, interior circular diameter are the 14-18 millimeter, thickly are the planchet of 2-4 millimeter, and one end outer rim projection thickness is the 0.5-1 millimeter, widely is the 2-3 millimeter.

Joint 3 is hollow circular cylinders of step more than, hollow diameters is the 8-12 millimeter, at one end diameter is a 18-22 millimeter, high for opening a high rectangular channel for 4-6 millimeter, dark 2-3 millimeter on the face of cylinder of 12-16 millimeter, at distance face of cylinder 3-5 millimeter place, what the face of cylinder joined therewith is a hexahedron that diameter is the 33-35 millimeter, what join with hexahedron is that a diameter is the cylinder of 14-17 millimeter, high 15-18 millimeter, is with screw thread on the cylinder.

Liquid-filling valve is assembling like this: on earlier spacing pad 4 small ends being put at the bottom of valve body 8 small ends up, then with valve seat 5, steel ball 6 is packed into successively, be screwed into gland nut and refill sealing mat 9, the one way valve 2 that installs is packed in the valve pocket 1, its large end face and valve pocket post bottom surface small sircle hole contact, and joint 3 are had screw thread one end to be screwed in the small sircle hole valve body 8 spiral shell buttons of valve pocket post baseplane again.

Liquid-filling valve is to use like this: the high pressure feed flow hole that the joint 3 of liquid-filling valve is inserted the push shifter reversal valves tightens with the U-shaped card, on valve body 8 small ends in the liquid injection pipe insertion valve pocket 1 of fluid injection gun, the fluid injection gun lock sleeve is inserted in the rectangular channel of valve pocket 8, after starting pumping plant, when the reversal valve handle of push shifter is got to the position of " pushing away ", high pressure liquid enters one way valve 2 through fluid injection gun and backs down the cavity of resorption that steel ball 6 injects push shifter, and push shifter then moves forward; When handle was got to the position of " drawing ", highly pressurised liquid entered one way valve 2 through fluid injection gun and backs down the epicoele that steel ball 6 injects push shifter, push shifter withdrawal original position.

The utility model has the advantages that: save the original connecting pipeline of push shifter, save substantial contribution; Working face has alleviated labor strength and a large amount of pipeline maintenance works because having reduced the clean and tidy manageability of pipeline; Method of operating is easy.

This liquid-filling valve can use the hard material of the various suitable processing such as steel, iron, copper, plastics to make.
