The rod body moves in the body, and one end of the rod body is convexly arranged at the body; the valve component is provided with a main control valve and an auxiliary control valve; one end of the main control valve is connected with the rod body and is provided with at least one flow conduit; the auxiliary control valve is provided with at least one throttling conduit, and the main control valve and the auxiliary control valve are connected by a spacing structure; and when the rod body pushes the main control valve at the moment of stress, the auxiliary control valve can be relatively close to the main control valve or be separated from the main control valve, and the flow of the working fluid is controlled by the flow conduit and the throttling conduit which are arranged on the main control valve and the auxiliary control valve so as to provide a buffering action.
Description
Technical field
The present invention is about a kind of flow control valve, and particularly a kind of main control valve and pair control valve are used and slowed down stressed flow control valve of moment for drawing close each other or separate.
Background technique
The vibrations and the noise that produce because of bump when preventing that object from drawing close mutually; Be to use rubber cushion and spring to come widely in early days as buffer structure; And present mostly use traffic control valve solves the problem of this type; It for example is applied between doorframe and the door-plate commonly, furniture or automatic machinery of working at high speed etc., however the present flow control valve that adopts, though the strength that object is produced is slowed down via friction; But in moderating process, can produce powerful drag of one moment; That is representing the kinetic energy that object produces to be absorbed fully in the very first time, and cause the generation of reaction force, cause the buffer function of flow control valve not good.
Therefore; Generally adopt air pressure and hydraulic type flow control valve at present; The kinetic energy of object converts heat energy into by gas or oil pressure liquid and discharges in also be about to moving; So cooperate this type of flow control valve then the start of object to be stopped stably, and then reduce significantly vibrations and the noise that object is produced among start.
For example; Be common in the various furniture for taking in the drawer member that article are used, after it uses, in the process of closing, form collision because of the application of force is excessive with the furniture body often; Not only can produce noise; Even can produce infringement because of colliding excessively, therefore, the furniture dealer solves this problem so that oil pressure or air pressure stream control valve to be installed.
Yet existing flow control valve only can reach the purpose of slow release pressure, does the time spent when it bears a unexpected external force; Can't this external force be absorbed this kinetic energy in stressed moment fully; And cause object to need to eliminate this kinetic energy with a reaction force, when for example under unexpected situation, applying an external force suddenly drawer being closed, because the flow control valve of convention slow release pressure only; Moment strength for this buffering range that surpasss the expectation; Must make drawer when closing, produce a reaction force and drawer is flicked outward, therefore, the flow control valve of convention exists in the not good problem of stressed moment buffer function.
Summary of the invention
In view of above problem, the present invention provides a kind of flow control valve with valve body structure that shape matees each other, and flow control valve can be absorbed because of the kinetic energy that buffer function produced, and can produce the problem of a reaction force with valve body in the solution existing technology.
The flow control valve that the present invention disclosed, it includes body, working fluid, the body of rod and valve assembly.Body has one first end and one second end, and in body, has a containing space and can supply working fluid to be filled in the body.The body of rod is arranged in the body with mobilizable relation, and the body of rod one end is convexly set in body one side.Valve assembly has a main control valve and a secondary control valve, and main control valve has at least one flow channel, and secondary control valve has at least one throttling channel.Main control valve one end is connected in the end that the body of rod is positioned at containing space, and can move in the lump with the body of rod.Main control valve is connected with a limit structure with secondary control valve.When the body of rod stressed and drive main control valve together and in the containing space of body, move; Make of the opposite direction displacement of secondary control valve towards main control valve; Make main control valve draw close mutually with pair control valve or separate, working fluid sees through flow channel and its flow of throttling controlling channel, and then reaches the purpose of buffer function.
The flow control valve that the present invention disclosed is that the main control valve with valve assembly is installed in the containing space of body regularly in another embodiment, and is connected with a limit structure and secondary control valve.Limit structure one end is connected in main control valve, and the other end is sheathed on secondary control valve.Simultaneously, the end that the body of rod is positioned at containing space has a pushing sheet, and when the body of rod moved in the containing space of body, push the work forward fluid and on pair control valve, produce a thrust of pushing sheet, secondary control valve received the effect of this thrust and draw close mutually with main control valve or separate.Working fluid by the throttling channel on the valve assembly and its flow of flow controlling channel to reach the buffering purpose.
The invention is characterized in; Main control valve on the valve assembly has at least one flow channel; Secondary control valve has at least one throttling channel, and when main control valve and pair control valve were drawn close mutually because of the effect of external force produces or separated, working fluid was by flow channel and the throttling controlling channel flow of main control valve with secondary control valve; Reduce vibrations to reach, reduce noise, and the purpose of one stable buffering is provided in stressed moment.
Below in mode of execution narration characteristic of the present invention and advantage; Its content is enough to make any people who is familiar with correlation technique to understand technology contents of the present invention and implements according to this; And according to content, the claim and graphic that this specification disclosed, any related art techniques person of being familiar with can understand aforesaid purpose of the present invention and advantage easily.
More than about the explanation of the explanation of content of the present invention and following mode of execution be in order to demonstration with explain principle of the present invention, and patent claim of the present invention explanation further is provided.
