Abstract
The invention relates to a new S-shape valve of irrigation rigid alloy layer, comprising an S-shape pipe, a connection sheath, a spline connection sheath, and an abrasion resistant bar, while using irrigation method to embed rigid alloy layer into part or whole of connection sheath and abrasion resistant bar. The invention can improve the abrasion resistance, prolong service life, improve anti-impact property and improve anti-tension property.
Description
Technical field
The present invention relates to the concrete pump S valve assembly in the building machinery.
Background technique
At present in the building machinery industry, concrete pump or to be referred to as to drag the assembly that is connected with glasses plate on pump and the car pump be the S valve assembly, in its using process the parts of easy loss be chromium-plated axle sleeve and wear-resisting muscle, chromium-plated axle sleeve mainly is to carry out chrome-faced with carbon steel or alloyed steel to handle, though the life-span increases, but use concrete still to have only the 2-3 ten thousand stere, greatly influenced the technical performance of concrete pump by the life-span amount of S valve pipe.Each concrete pump pump truck manufacturer requires to solve the problem in working life of S valve assembly one after another for this reason.
Summary of the invention:
Technical problem to be solved by this invention is: solve the problem that above-mentioned prior art exists, and provide a kind of by casting tungsten carbide button, greatly improve the Novel S valve assembly of the casting hard alloy layer that prolongs at double in wear resistance, shock resistance, tensile properties and working life.
The technical solution used in the present invention is: the Novel S valve assembly of this casting hard alloy layer has S pipe, connecting sleeve, spline connecting sleeve, wear-resisting muscle, one end of connecting sleeve and S pipe is connected and fixed, wear-resisting muscle is fastened on S pipe bottom, the spline connecting sleeve is fastened on S pipe top, and feature of the present invention is: adopt the part or all of tungsten carbide button layer of casting process to the connecting sleeve on the S valve assembly, wear-resisting muscle surface.
The present invention adopts casting process tungsten carbide button layer in the S of concrete pump valve assembly part easy to wear, not only greatly improved its wear resistance of S valve, and have satisfied shock resistance and a tensile properties, particularly greatly prolonged its working life, the life-span of using concrete to cross new S valve reaches more than the 4-6 ten thousand stere, and operating life is enhanced about more than once.The more important thing is a mosaic technology method and technology difficult problem that the invention solves cemented carbide and S valve connecting sleeve, wear-resisting muscle, because it is fixing that cemented carbide and connecting sleeve inwall are difficult to welding, and cemented carbide is in electric welding, easily split, in like manner, it is fixing that cemented carbide and wear-resisting muscle also are difficult to welding, like this, casting process of the present invention just provides a kind of new technological method for cemented carbide is connected with inlaying of S valve, has solved this technical barrier.
Description of drawings:
Fig. 1 is a structure sectional view of the present invention
Fig. 2 is the left view of Fig. 1
Embodiment:
Referring to Fig. 1, the Novel S valve assembly of this casting hard alloy layer, concrete S pipe 1, connecting sleeve 2, spline connecting sleeve 3, wear-resisting muscle 4, connecting sleeve 2 is connected and fixed with an end of S pipe 1, wear-resisting muscle 4 is fastened on S and manages 1 bottom, spline connecting sleeve 3 is fastened on S and manages 1 top, and feature of the present invention is: adopt the part or all of tungsten carbide button layer 5 of casting process to the connecting sleeve on the S valve assembly 2, wear-resisting muscle 4 surfaces.
Connecting sleeve and wear-resisting muscle preparation process: press one of connecting sleeve and wear-resisting muscle size requirement making, two or more cemented carbide cylinder or piece, carry out the steel casting by pattern, alloy and steel body are inlayed, for the ease of welding with the S pipe, stay the steel body of 5-10mm not inlay alloy in the welding part, its effect can also be played the effect of reinforcing alloy and resisting impact except helping welding.
The hard alloy layer 5-8mm of connecting sleeve or wear-resisting muscle is thick, and the steel body adopts steel casting way, and steel bushing thickness is 2-5mm, and the steel body is selected plain carbon steel or alloyed steel for use, and hard alloy layer adopts and is easy to and the identical cemented carbide of steel body.
For preventing its distortion, the present invention adopts 600 ℃ of-850 ℃ of quenching with Subsequent tempering in S valve working process, also can carry out carburizing or boronising processing to the S valve by temperature in the stove in heat treatment process, to improve the wear resistance of valve body S tube wall.
Claims (2)
1. the Novel S valve assembly of a casting hard alloy layer, have S pipe, connecting sleeve, spline connecting sleeve, wear-resisting muscle, one end of connecting sleeve and S pipe is connected and fixed, wear-resisting muscle is fastened on S pipe bottom, the spline connecting sleeve is fastened on S pipe top, it is characterized in that adopting partly or entirely splice the fixedly hard alloy layer of casting process to the connecting sleeve on the S valve assembly, wear-resisting muscle surface.
2. the manufacture method of the Novel S valve assembly of casting hard alloy layer according to claim 1, it is characterized in that preparation process is: press one of connecting sleeve and wear-resisting muscle size requirement making, two or more cemented carbide cylinder or piece, carry out the steel casting by pattern, alloy and steel body are inlayed, stayed the steel body of 5-10mm not inlay alloy in welding part with the S pipe.
