Problems solved by technology

[0003] Nowadays, the air compressor distribution system mainly uses ordinary high-speed on-off valves as the pilot stage, and the main stage uses mechanical valves. The structure is complex, the reliability is low, and the frequency response is low, which greatly limits the performance of the air compressor distribution system.

Embodiment Construction

[0017] Such as Figure 1-3 As shown, a springless quick-response valve includes an electromagnet shell 1, a hexagonal thin nut 2, a magnetic isolation copper sheet 3, an electromagnet sleeve 4, an armature 5, a battery iron coil 6, a skeleton 7, and an electromagnet core 8 , push rod 9, electromagnet retaining ring 10, valve seat 11, large liquid resistance 12, small liquid resistance 13 and plug 14. Such as figure 2 As shown, the two ends of the valve seat 11 are opened, which are respectively the first opening and the second opening. Along the direction from the second opening to the first opening, the valve seat 11 is provided with a first radial through hole and a second radial through hole in sequence. The openings of the first radial through hole, the second radial through hole and the third radial through hole are P port, A port and T port respectively; the first opening is used for mounting Enter the large liquid resistance 12 and be connected with the electromagnet...

Abstract

The invention discloses a springless quick-response valve which comprises an electromagnet housing, a hexagon thin nut, a magnetism isolated copper sheet, an electromagnet sleeve, an armature, a battery iron coil, a framework, an electromagnet core and a push rod. No spring exists in a structure of the hydraulic valve, so that the original spring part in the structure of the hydraulic valve is omitted, and the structure is simplified and is more compact; the resistance during the opening and the closing of the valve is reduced; the response time is shortened; frequency response is increased; in addition, the oil-liquid heat exchange and cooling efficiency of a system is improved.

Description

technical field [0001] The invention relates to a springless quick-response valve which can realize quick response and is applied to a flow distribution system of an air compressor. Background technique [0002] The air compressor is a working machine that converts the power energy of the prime mover into gas pressure energy. It is called "general machinery" in the industrial field and is widely used in chemical industry, electric power, petroleum, metallurgy and other industries. Among them, the flow distribution system is the core part of the compressor. Its main function is to adjust the flow and pressure parameters of the fluid medium by mechanical, electronic, hydraulic and other methods, so as to meet the fluid control requirements under various host working conditions. [0003] Nowadays, the air compressor distribution system mainly uses ordinary high-speed on-off valves as the pilot stage, and the main stage uses mechanical valves. The structure is complex, the relia...
