Design method of valve for unloading double abrasive tanks and reversing sand-water mixture in front-mixing water cutting jet

Abstract

The invention discloses a design method of a valve for unloading double abrasive tanks and reversing a sand-water mixture in a front-mixing water cutting jet. A mixed water unloading reversing valve block, a abrasive tank A liquid inlet joint, a reversing motor, an abrasive tank B liquid inlet joint, a mixed water outlet joint, a tank A liquid supply valve seat, a tank A liquid supply opening andclosing valve core, a tank A liquid supply valve core reversing sleeve, a tank A liquid supply rotating gear, a motor-driven driving gear, a tank A sand removal unloading rotary gear, a tank A sand removal unloading valve element reversing sleeve, a tank A sand removal unloading valve element, a tank A sand removal unloading valve seat, a tank A sand removal unloading connector, a tank B sand removal unloading connector, a tank B liquid supply valve seat, a tank B liquid supply opening and closing valve element, a tank B liquid supply valve element reversing sleeve, a tank B liquid supply rotary gear, a tank B sand removal unloading rotary gear, a tank B sand removal unloading valve element reversing sleeve, a tank B sand removal unloading valve element and a tank B sand removal unloadingvalve seat are combined into a whole to form a set of valve for automatically unloading double abrasive tanks and reversing sand-water mixture in a front-mixing water cutting jet.

Description

technical field [0001] The invention relates to a design method of a sand-water mixing automatic unloading reversing valve for a double abrasive tank front-mixing water cutting machine, specifically a device capable of reversing the sand-water mixed water output from the abrasive tank and unloading the abrasive tank device. Background technique [0002] At present, the structure of the pre-mixing waterjet cutting machine is mainly composed of high-pressure pumps, high-pressure rubber hoses, A abrasive tanks, cutters and other components; Abrasive tank A adds pomegranate sand to play a cutting role during cutting. When A abrasive tank pomegranate sand When it is exhausted, it needs to stop and add sand, such a waterjet machine cannot cut continuously; this requires adding another B abrasive tank to the high-pressure pipeline system, and when the pomegranate sand in A abrasive tank is about to run out, switch to B abrasive tank Work, use the pomegranate sand and high-pressure...

AI Technical Summary

Problems solved by technology

[0003] The present invention solves the structure of the "pre-mixing water cutting machine", which is mainly composed of high-pressure pump, high-pressure rubber hose, A abrasive tank, cutter and other components; adding pomegranate sand in the A abrasive tank plays a cutting role when cutting, when A When the pomegranate sand in the abrasive tank is exhausted, it is necessary to stop and add sand, such a waterjet machine cannot cut continuously; it is necessary to add another B abrasive tank to the high-pressure pipeline system, and when the pomegranate sand in the A abrasive tank is about to be exhausted, switch to Go to the B abrasive tank to work, use the pomegranate sand in the B abrasive tank and the high-pressure water to cut the object, and at the same time depressurize the pressure system of the A abrasive tank and add sand; there is no high-pressure mixing when the A abrasive tank is output When the water and the high-pressure mixed water output by the B abrasive tank are reversed, a device that can not only reverse the direction of the mixed water, but also relieve the pressure of the abrasive tank can solve this problem. A double abrasive tank is proposed The design method of the sand-water mixing automatic unloading reversing valve of the front-mixing water cutting machine achieves the purpose of the design method of the sand-water mixing automatic unloading reversing valve of the double-abrasive tank front-mixing water cutting machine
