Embodiment Construction
[0014] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.
[0015] A throttle valve with double spool structure, such as figure 1 As shown, a valve body 8 is included, the bottom of the valve body 8 is provided with a base 10 and the top is provided with a top cover 2, the inside of the valve body 8 is provided with a corresponding upper valve core 4 and a lower valve core 7, and an adjustment push rod 1 The top cover 2 is connected to the upper spool 4. Preferably, the top of the adjusting push rod 1 is provided with a handle for easy adjustment. By adjusting the push rod 1, the upper spool 4 moves vertically to change the flow area of the orifice. The top cover 2 is provided with a guide sleeve 3 wrapp...

The invention discloses a throttle valve of a double-valve-element structure. The throttle valve comprises a valve body. The bottom of the valve body is provided with a base, and the top of the valve body is provided with a top cover. The throttle valve is characterized in that the valve body is internally provided with an upper valve element and a lower valve element corresponding to each other, an adjusting push rod penetrates through the top cover and is connected with the upper valve element, the bottom of the lower valve element is provided with a reset spring, the valve body is provided with an oil inlet and an oil outlet, a throttling opening is formed between the upper valve element and the lower valve element and capable of connecting the oil inlet and the oil outlet or cutting off the oil inlet and the oil outlet, the lower valve element is connected with the oil inlet through a downwards-inclined oil inlet channel, and the top of the lower valve element is provided with a gap communicated with the inclined oil inlet channel. According to the throttle valve of the double-valve-element structure, the upper valve element and lower valve element structure is adopted, the throttling opening area is adjustable and is in positive correlation with the oil pressure of inlet oil, the control accuracy is high, and the structure is simple.
Description
technical field [0001] The invention relates to a double-spool structure throttle valve. Background technique [0002] The throttle valve is a valve that controls the flow of fluid by changing the flow area of the throttle. So far, the throttle valve has a variety of structures, including ordinary throttle valve, precision throttle valve, one-way throttle valve, throttle stop valve and so on. Among them, the one-way throttle valve has an upper and lower spool structure, but its upper spool and lower spool are both spools of existing design, its throttling principle is the same as that of ordinary throttle valves, and its control accuracy is not high. Contents of the invention [0003] In view of the above problems, the present invention provides a throttle valve with a double-spool structure, which adopts an upper and lower spool structure, and its orifice area is adjustable, and is positively correlated with the oil pressure of the oil inlet, with high control precisio...
