Problems solved by technology

At present, the inflation and deflation connection devices used by domestic and foreign pneumatic hydraulic companies usually have a single air circuit structure. After the inflation operation is completed during the work process, there is a shortcoming that the deflation operation can only be completed after the gas source is removed, and fast charging cannot be achieved. , The function conversion of deflation, and if it is necessary to inflate multiple pressure vessels at the same time, an air plug is required, which is not convenient for actual operation

Embodiment Construction

[0034] Such as figure 1 As shown, the present invention proposes a quick inflation and deflation connection device, including: a valve assembly 1, a handle 2, a valve stem assembly 3, a dial assembly 4, a slip ring 5, a housing 6 and a joint 7;

[0035] The valve stem assembly 3 is arranged inside the casing 6, and the slip ring 5 is set on the opening end of the casing 6, and is used for limiting when the opening end of the casing 6 is connected with the external inflation nozzle;

[0036] One end of the dial assembly 4 is fixedly connected to the valve stem assembly 3, and the other end is set on the housing 6, and the position is limited by a steel ball; the dial assembly 4 is driven to rotate the valve stem assembly 3, and the valve stem assembly 3 is made to rotate through the handle 2. The axial movement along the casing 6 makes the valve assembly 1 open or close; the joint 7 is connected with the casing 6 for connecting the air circuit.

[0037] Such as figure 2 As s...

Abstract

The invention discloses a quick inflation / deflation connection device which comprises a valve component, a handle, a valve rod component, a stirring clamp component, a slip ring, a shell and a joint,wherein the valve rod component is arranged inside the shell; the slip ring is sleeved with an opening end of the shell and is applied to limiting when the opening end of the shell is connected with an external inflation mouth; one end of the stirring clamp component is fixedly connected with the valve rod component, and the other end is arranged on the shell and is limited by a steel ball; the stirring clamp component is stirred to drive the valve rod component to rotate, and a handle enables the valve rod component to move in the axial direction of the shell so as to open or close the valvecomponent; the joint is connected with the shell and is used for connecting an air path. The structural innovation of the valve rod realizes quick switch between the inflation and deflation air pathsof the quick inflation / deflation connection device. The quick inflation / deflation connection device overcomes the shortcoming of the prior art that only inflation or deflation can be realized by oncemounting and the air source needs to be removed or the joint needs to be changed for switching the two functions. The switch between the inflation and deflation air paths is realized by the stirring clamp component driving the position change of the valve rod, thus inflation and deflation are realized conveniently and quickly without removing the air source.

Description

technical field [0001] The invention relates to a fast charging and discharging connection device, which is used on a pressure accumulator of a servo mechanism. Background technique [0002] Pressure vessels such as pressure accumulators are usually used for buffering and storing pressure in pressure systems, and they need to be charged and deflated during production, testing and use. At present, the inflation and deflation connection devices used by domestic and foreign pneumatic hydraulic companies usually have a single air circuit structure. After the inflation operation is completed during the work process, there is a shortcoming that the deflation operation can only be completed after the gas source is removed, and fast charging cannot be achieved. , The function conversion of deflation, and if it is necessary to inflate multiple pressure vessels at the same time, an air plug is required, which is not convenient for actual operation. Contents of the invention [0003...
