Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing:

[0015] As shown in Figure 1, the electromagnetic pilot-operated high-pressure two-position three-way valve provided by the present invention, wherein the valve body is composed of a split left valve body 1 and a right valve body 15, and is connected by bolts 14 to form an integral structure, the upper end The threaded plug 12 is the technological structure of the channel 16, and a solenoid valve 7 is connected to the valve body, and its internal characteristic structure is as follows:

[0016] a. The valve body 1 is provided with an air inlet 23 and the air inlet passages 2 and 16 which are connected to the air inlet 23 and are arranged in the valve body leading to both sides. The valve body is also provided with a left valve chamber 5 and an air inlet. The channel 2 is matched, and a solenoid valve 7 is connected to the valve body. The solenoid valve core 6 in the solenoid...

Abstract

The invention relates to an electromagnetic pilot operated high pressure two-position three-way valve which is characterized in that a valve (1) is provided with a valve plug (3) and an elastic ejector rob (17) which is contacted with a steel ball (11); when an electromagnetic valve plug (6) retracts, a discharge port (8) is closed by the electromagnetic valve plug (6); a left valve chamber (5) is communicated with an inlet channel (2); as the end area of the valve plug (3) is larger than the area of a hole (19), a high pressure difference pushes the valve plug, a hole at the right side of a seal seat (18) is closed by a steel ball, and an discharging channel (10) is communicated with an emptying channel (9); when the electromagnetic valve plug (6) extends, the inlet channel (2) is closed, and the left valve chamber (5) and the discharge port (8) are communicated with air, here, the steel ball is pushed to the left side and sealed by the pressure difference, the discharging channel (10) is communicated with an inlet channel (16). The invention has the advantages of simple structure, convenient use, high control precision, application of high pressure.

Description

technical field [0001] The invention relates to a high-pressure gas or liquid control device, in particular to an electromagnetic pilot type high-pressure two-position three-way valve. Background technique [0002] In the field of air compressors, especially in the field of post-processing equipment for drying and purifying compressed air, general equipment must use 5 solenoid valves, 5 pneumatic actuators and 5 high-pressure ball valves to cooperate with each other to achieve the opening of various air circuits. or off purpose. Because they need to be connected and installed with pipelines, it has the disadvantages of complex structure, bulky size, poor efficiency, and inconvenient use, which makes the external connection pipelines and components of compressors or drying and purification equipment too complicated and prone to various problems. Fault. Can the functions of the above solenoid valve, pneumatic actuator and high pressure ball valve be integrated to overcome th...
