Abstract

The invention relates to the field of pipeline cleaning equipment, and discloses a multifunctional high-pressure spray head for cleaning pipeline scabs. The nozzle body is internally provided with small-inclination-angle and large-inclination-angle spray holes distributed in a circumferential array. The gear adjusting component adjusts the internal water flow channel to realize three-gear switching, namely, the first-gear small-inclination-angle water spray main attack strong striking, the second-gear large-inclination-angle water spray provides the fastest self-advancing speed, and the three-gear bidirectional cooperative water spray realizes stable self-advancing and strong striking balance. The spray head can be combined into tens of cleaning modes with different self-advancing speeds and striking forces by combining with the spray holes which are not used by the blind plug plugging part so as to adapt to high-pressure plunger pumps with different pressures and flows. The inside of the valve core is provided with an independent high-precision valve core module and a metal-to-metal hard sealing structure, and the locking of the gear under ultra-high pressure is ensured to be firm by matching with a fixing mechanism. The invention reduces hardware investment and maintenance cost and improves equipment operation stability.

Description

Multifunctional high-pressure spray head for cleaning pipeline scab Technical Field The invention relates to the technical field of pipeline cleaning equipment, in particular to a multifunctional high-pressure spray head for cleaning pipeline scabs. Background Pipe scarring is an unavoidable problem in long-term operation of industrial pipes, which can severely increase fluid resistance and reduce delivery efficiency, and typically requires cleaning by high pressure cleaning techniques. Currently, high pressure nozzles are used in the industry to operate in combination with high pressure plunger pumps, and the ejected high pressure water flow is used to physically impact the pipe wall to strip the scab. Most of the existing high pressure nozzles are generally integrally formed, are relatively simple in structure, are generally provided with only a single set of fixed-inclination spray holes, and provide basic cleaning coverage through circumferential array arrangement. For the high-pressure spray heads with a plurality of cleaning modes, when the high-pressure spray heads are used for coping with different operation scenes, operators are mostly required to manually detach and replace specific spray hole assemblies and even the whole spray head body. In the aspects of core fluid control and sealing, the conventional high-pressure nozzles mostly lack independent high-precision valve core modules, and mainly rely on conventional rubber pieces to realize isolation and sealing of an internal high-pressure waterway. However, the prior art has exposed a number of drawbacks in dealing with complex and variable industrial pipe cleaning conditions. The traditional spray head with a single spray hole dip angle is solidified, and the balance between strong striking for breaking hard and stubborn scars and quick self-advancing thrust required for long-distance operation cannot be obtained. The spray head with the multi-mode switching function is excessively dependent on complicated disassembly and replacement operations, so that the on-site downtime and the operation intensity are increased, and the operation risk in the high altitude or the closed space is also increased. Meanwhile, the traditional spray heads are lack of flexible flow distribution and customized configuration capability, one type of high-pressure pump can only be used for dead-plate matching of specific pressure and flow, multiple groups of spray holes cannot be flexibly plugged and combined according to actual demands, so that construction parties must purchase and carry a large number of independent spray heads with different specifications, and hardware investment and maintenance cost are increased. In addition, the high-pressure sealing performance of the waterway inside the traditional integral spray head is poor, the pure rubber sealing piece is extremely easy to damage and leak under ultrahigh pressure impact, and the existing gear adjusting or mode switching structure is generally insufficient in locking rigidity, so that gear shifting and even mechanical failure are easy to occur when the equipment bears extremely high water flow impact, and the cleaning effect and the running stability of the equipment are seriously influenced. Disclosure of Invention Aiming at the defects of the prior art, the invention provides a multifunctional high-pressure spray head for cleaning pipeline scabs, which solves the problems that the water spray gear can not be switched during pipeline cleaning and the requirements of different striking forces and self-advancing speeds are difficult to be met. The multifunctional high-pressure spray head for cleaning the scab of the pipeline comprises a spray head body, wherein a water outlet mechanism is arranged in the spray head body and used for receiving high-pressure water flow conveyed by the inside of a water inlet assembly and guiding the high-pressure water flow to the outside to form sprayed water flow; the gear adjusting assembly is used for adjusting the internal water flow channel of the water inlet assembly according to the cleaning requirement and controlling the switching of different water spraying modes; The water inlet assembly is used for introducing high-pressure water flow into the nozzle body and distributing the water flow by being connected with an external high-pressure water source; The fixing mechanism is used for keeping the adjusting position of the gear adjusting assembly unchanged after the gear adjusting of the gear adjusting assembly is completed; the water outlet mechanism comprises small-inclination spray holes, a conical table and large-inclination spray holes, the small-inclination spray holes are circumferentially arranged in the cylindrical surface of the spray head body, the conical table is connected to the bottom of the spray head body, and the large-inclination spray holes are circumferentially arranged in the conical table; And the blind plug is arranged in the small-inclination
