[0003] The prior art requires valves and related control elements to be set at each air inlet and outlet, which makes the operation inconvenient when performing one-way air intake, and the setting of multiple valves and control elements also makes the entire device not light and simple enough. Therefore, it is necessary to design a new type of double-tower air dryer connector with one-way air intake function with air path control to solve the above problems. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a double-tower air dryer connector with air path control, which solves the problem that the traditional double-tower air dryer in the prior art needs to be provided with valves and related control components at each air inlet and outlet, resulting in inconvenient operation when performing one-way air intake.

[0005] To achieve the above-mentioned purpose, the utility model proposes a double-tower air dryer connector with air path control, including a valve body, valve covers are symmetrically fixedly installed at both ends of the valve body, a piston rod is fixedly installed in the valve body, pistons are symmetrically slidably connected at both ends of the piston rod, a guide belt and a combined sealing ring are fixedly installed on the piston, a working chamber is formed between the piston, the valve body and the valve cover, a pair of axial long holes are symmetrically opened on the valve body, one end of the axial long hole leads to the outside of the valve body, and the other end leads to the working chamber, a solenoid valve is fixedly installed on the valve body, the solenoid valve is fixedly connected to one end of the axial long hole leading to the outside of the valve body, a control air transition block is fixedly installed on one side of the valve body, a steering hole is opened in the valve body, a drilled hole is opened on the valve body, one end of the steering hole leads to the drilled hole, and the other end leads to the control air transition block.

[0006] As a further solution of the utility model: the valve body and the valve cover are both made of lightweight aluminum alloy material.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. By setting a solenoid valve, a control air transition block, an axial long hole, a drilled hole, a steering hole, and a working chamber, when the control air path enters from the drilled hole, it enters the control air transition block through the steering hole, and then runs axially to the solenoid valve through the control air transition block. Then, through the periodic control of the solenoid valve, the control air is turned to the axial long hole, and then enters the working chamber through the axial long hole, pushing the piston to slide. The sliding of the piston pushes the gas into the air inlet connected thereto, thereby realizing the air intake of the air inlet, thereby eliminating the need to set valves at the inlet and outlet, and at the same time realizing periodic one-way air intake.

[0021] like Figure 1-6As shown, a double-tower air dryer connector with air path control includes a valve body 1, valve covers 2 are symmetrically fixedly installed at both ends of the valve body 1, and the valve body 1 and the valve cover 2 are both made of lightweight aluminum alloy material, in order to achieve lightweight overall components; a piston rod 3 is fixedly installed in the valve body 1, pistons 4 are symmetrically slidably connected at both ends of the piston rod 3, and an air inlet is arranged between the symmetrically arranged pistons 4, and the air inlet is opened on the valve body 1, and a guide belt 5 and a combined sealing ring 6 are fixedly installed on the piston 4. The installation purpose of the guide belt 5 is to prevent the piston 4 from deflecting due to uneven external force, and at the same time reduce the piston 4 and the valve cover. The contact between the piston 4 and the valve body 1 is improved, that is, the wear of the piston 4 is reduced. The purpose of setting the combined sealing ring 6 is to increase the sealing between the piston 4 and the valve body 1. The end of the piston 4 away from the combined sealing ring 6 is provided with an O-ring 7 and a sealing seat 8. The O-ring 7 and the sealing seat 8 are fixedly connected to the piston 4 to ensure the sealing between the piston 4 and the valve body 1, that is, to facilitate the sliding of the piston 4 in the valve body 1. A working chamber 14 is formed between the piston 4, the valve body 1 and the valve cover 2. A pair of axial long holes 11 are symmetrically opened on the valve body 1. One end of the axial long hole 11 leads to the outside of the valve body 1, and the other end leads to the working chamber 1 4. A solenoid valve 9 is fixedly installed on the valve body 1. The solenoid valve 9 is fixedly connected to one end of the axial long hole 11 leading to the outside of the valve body 1. If the solenoid valve 9 is not provided on the axial long hole 11, a steel ball is used to block the outlet; to increase the air tightness of the device; a control air transition block 10 is fixedly installed on one side of the valve body 1, a steering hole 13 is provided in the valve body 1, a drill hole 12 is provided on the valve body 1, one end of the steering hole 13 leads to the drill hole 12, and the other end leads to the control air transition block 10, and a transfer groove is provided in the control air transition block 10, one end of the groove is fixedly connected to the steering hole 13, and the other end is connected to the solenoid valve 9 through a transmission pipe The output port is fixedly connected. The purpose of the above setting is that the control air path enters from the drill hole 12, enters the control air transition block 10 through the turning hole 13, and then runs axially to the solenoid valve 9 through the control air transition block 10. Then, through the periodic control of the solenoid valve 9, the control air is turned to the axial long hole 11, and then enters the working chamber 14 through the axial long hole 11, pushing the piston 4 to slide, thereby realizing the main air path conversion; the control air path can be designed by drilling holes according to the machining allowance of the wall thickness of the valve body 1 or sealing with steel balls after drilling, and converting the line through the control air transition block 10, so as to realize the unilateral closure of the main air path and the opening of the main air path on the other side.

[0022] Working principle:

[0023] When the control air path enters from the drill hole 12, it enters the control air transition block 10 through the turning hole 13, and then runs axially to the solenoid valve 9 through the control air transition block 10. Then, through the periodic control of the solenoid valve 9, the control air is turned to the axial long hole 11, and then enters the working chamber 14 through the axial long hole 11, pushing the piston 4 to slide. The sliding of the piston 4 pushes the gas into the air inlet connected thereto, realizing the air intake of the air inlet, thereby realizing the periodic unidirectional air intake of the entire device.
