Problems solved by technology

[0005] The purpose of the present invention is to provide a control valve and a hydraulic pump to solve the above-mentioned problems in the background technology that when in use, the matching control valves often need to be connected through flanges, so that the hydraulic pump cannot interface with control valves of different sizes. Efficient connection and fixation not only leads to poor universality of adaptation, but also low connection effect and efficiency

Abstract

The control valve comprises the hydraulic pump, the control valve, a pump body, a connecting base and a transmission motor, the hydraulic pump is fixedly connected with a pressure tank, one end of the hydraulic pump is fixedly connected with a blade cover, the other end of the hydraulic pump is fixedly connected with a connecting body, and the connecting body is fixedly connected with the pump body. According to the device, a transmission motor, a hydraulic pump and a control valve are arranged, and when the device is used, the transmission motor is controlled to operate, so that a first fixing block is driven to move, a connector of the control valve is preliminarily fixed, a second fixing block is driven to move, and a connecting pipe is clamped and fixed; and meanwhile, the first connecting ring and the second connecting ring are driven to move, a connector or a connecting pipe is effectively connected and fixed, the connecting convenience is effectively improved, meanwhile, when connecting flanges of different sizes are connected, quick connecting and fixing can be conducted, the working efficiency is improved, and the connecting applicability is improved.

Description

technical field [0001] The invention relates to the field of hydraulic pumps, in particular to a control valve and a hydraulic pump. Background technique [0002] The hydraulic pump is a kind of pump specially designed for pressurizing water, hydraulic oil, emulsion, alcohol, etc. It adopts a single air-controlled unbalanced gas distribution valve to realize the automatic reciprocating motion of the pump. The air drive part of the pump body is made of aluminum alloy. The parts in contact with the liquid are all made of stainless steel. The principle of pushing a small-area piston by a large-area piston is used, and a small air pressure is applied to the large-area piston end, and a corresponding multiple of pressurized liquid or gas can be obtained at the small-area piston end. As the output pressure increases, the working speed of the pump gradually slows down until it stops. At this time, it is in a pressure-holding state, and there is no more energy consumption.
