Technical Field

The invention relates to the field of valves, in particular to an opening and closing mechanism of an aerodynamic valve.

Background

The air power valve is widely applied to controlling air charging and discharging in an automobile air suspension system, is used for adjusting the posture of an automobile body, is a valve widely applied and is opened and closed by means of pneumatics.

The existing Chinese patent with publication number CN110701369A discloses an air valve, which comprises a valve body, wherein a valve cavity with an opening at the bottom is arranged in the valve body, a quick exhaust passage communicated with the valve cavity is arranged at the upper end of the valve body, a valve core mechanism capable of moving up and down is arranged in the valve cavity, the valve core mechanism can close or open the quick exhaust passage in the process of moving up or down, and a signal feedback device for detecting the moving position of the valve core mechanism is arranged in the quick exhaust passage; through a signal feedback device arranged in the quick exhaust channel and used for detecting the moving position of the valve core mechanism.

The air valve has the advantage of avoiding the situation that the valve core mechanism is not disposed of in time after being stuck, but the air valve still has some disadvantages, such as: the valve can not change the conduction state according to the pressure, namely, the two ways are disconnected when the pressure is small, and the two ways are kept to be communicated after the pressure is a certain value.

Disclosure of Invention

In view of the problems mentioned in the background, the present invention is directed to an opening and closing mechanism of an aerodynamic valve to solve the problems mentioned in the background.

The technical purpose of the invention is realized by the following technical scheme:

the utility model provides an opening and closing mechanism of aerodynamic valve, is including seting up the first valve pocket in the valve body, the internal sliding of first valve pocket is connected with first piston, first piston with be connected with first return spring between the first valve pocket top, the both ends side of first piston is fixed with first slide bar and second slide bar respectively, the confession has still been seted up in the valve body first slide bar with the gliding first slide chamber of second slide bar and second slide chamber, still seted up in the valve body with first air inlet, second air inlet, first gas outlet and the second gas outlet that the first valve pocket communicates each other, first slide bar with set up jointly in the first piston will first air inlet with the runner of first gas outlet intercommunication.

By adopting the technical scheme, when the opening and closing mechanism of the aerodynamic valve is used, the first air inlet and the second air inlet can be independently connected with the air inlet pipeline, when the air flows injected into the first air inlet and the second air inlet keep relatively constant pressure, the first piston in the first valve cavity is pushed to move downwards, so that the second air inlet and the second air outlet are communicated through the flow passage, when the air flow introduced from the first air inlet and the second air inlet keeps constant pressure, the passage between the first air inlet and the first air outlet and the passage between the second air inlet and the second air outlet are communicated, when the pressure in the first valve cavity is lower, the return spring drives the first piston to move upwards, therefore, the two paths are closed, so that the opening and closing mechanism of the aerodynamic valve can directly disconnect the two paths when the pressure is low, and can simultaneously connect the two paths when the pressure is higher than a certain condition.

Preferably, a second piston is fixed outside the second movable rod, and a second valve cavity for the second piston to slide is formed in the valve body.

Through adopting above-mentioned technical scheme, utilize the cooperation of second piston and second valve chamber can increase the gliding stability of first slide bar and second slide bar.

Preferably, a second return spring is connected between the second piston and the top of the second valve cavity.

Through adopting above-mentioned technical scheme, the second return spring between second piston and the second valve chamber can increase the restoring force of second piston.

Preferably, the first valve cavity is provided with a first sinking groove in a jacking manner, and one end of the first return spring is connected to the bottom of the first sinking groove.

Through adopting above-mentioned technical scheme, the stability of first return spring when connecting the valve body can be increased in the setting of first heavy groove.

Preferably, a second sinking groove is formed in the top surface of the first piston, and one end of the first return spring is connected to the bottom of the second sinking groove.

Through adopting above-mentioned technical scheme, the stability of first return spring connection when first piston can be increased in the setting of the heavy groove of second.

Preferably, the valve body is provided with a first air inlet pipe and a second air inlet pipe which are integrally formed with the valve body at the first air inlet and the second air inlet.

Through adopting above-mentioned technical scheme, the existence of first intake pipe and second intake pipe makes the valve can make things convenient for external pipeline.

Preferably, the valve body is provided with a first air outlet pipe and a second air outlet pipe which are integrally formed with the valve body at the first air outlet and the second air outlet.

Through adopting above-mentioned technical scheme, the existence of first outlet duct and second outlet duct makes the valve can make things convenient for external pipeline.

In summary, the invention mainly has the following beneficial effects:

this mechanism that opens and shuts of aerodynamic valve is when using, first air inlet and second air inlet can be connected with the air inlet pipeline alone, when the air current of pouring into in first air inlet and the second air inlet keeps comparatively invariable pressure, first piston in the first valve intracavity will be promoted and move down, make the runner switch on second air inlet and second gas outlet, when the air current that first air inlet and second air inlet let in keeps the constant voltage, route between first air inlet and the first gas outlet, route between second air inlet and the second gas outlet all will be switched on, when pressure in the first valve intracavity is less, return spring can drive first piston and go upward, thereby seal two routes all, so this mechanism that opens and shuts of aerodynamic valve can directly break off two routes when pressure is less, switch on two routes simultaneously when pressure is greater than certain condition.
