Abstract
The utility model relates to a hard alloy fracturing nozzle which comprises a hard alloy nozzle body and a hollow hard alloy pressing cap, wherein the pressing cap consists of a frustum part with one end in a hollow frustum shape and a hollow cylindrical part with the other end in a hollow cylindrical shape; the nozzle body is a hollow cylinder and is fixedly embedded in the circular counter bore.
Description
Technical Field
The utility model relates to a hard alloy fracturing nozzle.
Background
The fracturing nozzle is high in fluid pressure and speed, the nozzle is required to be made of hard alloy with high hardness and wear resistance, and when the nozzle is installed and disassembled, the external thread tool withdrawal groove of the integral hard alloy nozzle is a weak link, so that the nozzle is easy to break after being stressed and cannot be normally assembled and disassembled. Firstly, mortar fluid sprayed out of the fracturing nozzle is splashed back and then sprayed onto the nozzle outer sleeve, so that the end face of the outer sleeve and the inner hexagonal counter bore are eroded and deformed, the service life of the nozzle is shortened, the nozzle is difficult to disassemble, and the whole component cannot be reused; secondly, the nozzle structure of the composite nozzle is complex, and the periphery of the nozzle is designed with steps, so that when a semi-finished product is formed, cracks are easy to appear, and the qualified rate of the finished product is reduced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that the hard alloy fracturing nozzle can solve the problem that the end face and the inner hexagonal of the outer sleeve of the nozzle are quickly eroded, the reuse of the whole set of parts is ensured, and the nozzle body is simple in structure and high in qualification rate. The utility model also solves the problem of easy breakage of the tool withdrawal groove of the external thread of the hard alloy nozzle.
A hard alloy fracturing nozzle comprises a hard alloy nozzle body and a hollow hard alloy pressing cap, wherein the pressing cap consists of a frustum part with one end in a hollow frustum shape and a hollow cylindrical part with the other end, a hollow inner cavity of the frustum part is a hexagonal hole, threads are arranged on the peripheral surface of the cylindrical part, and a circular counter bore is formed in the hollow inner cavity of the cylindrical part; the nozzle body is a hollow cylinder and is fixedly embedded in the circular counter bore.
The nozzle body adopting the structure of the utility model has a cylindrical structure, has simple structure, and improves the qualification rate no matter the semi-finished product is formed or sintered. The whole nozzle body is fixedly embedded in the hard alloy pressure cap, and mortar fluid sprayed from the fracturing nozzle is splashed back and then sprayed onto the pressure cap, so that the mortar fluid can be sufficiently resisted from erosion deformation, particularly a cone table part of the pressure cap.
In a further improvement, the nozzle body is made of underestimated hard alloy, so that the service life of the nozzle body is prolonged.
Further improvement, this patent adopts moderate well cobalt carbide preparation of hardness and intensity to press the cap, has further improved the intensity of pressing the cap to adopt the mode of brazing to link together the pressure cap and the nozzle body part of two kinds of carbide materials. The smooth installation and disassembly of the connecting part are ensured.
