Description

Title: SHOCK OR IMPACT ACTIVATED FLUID FLOW STOPPING SYSTEM AND A METHOD THEREOF.
FIELD OF THE INVENTION:
The present invention relates to impact based fluid flow controlling technology. More specifically, the present invention is directed to develop a system for stopping flow of the fluid through a fluid channel depending on impact/shock/vibration applied on said system/fluid channel by any means and an automated method of stopping flow of the fluid through the fluid channel involving such shock or impact sensitive fluid flow stopping system.
BACKGROUND OF THE INVENTION:
There are many instances wherein flow of a liquid medium/fluid running through a guiding means or fluid channel needs to be stopped for serving different objectives. E.g. modern day cars include air bags which are impact activated . These air bags are made in such a way that if the car gets a hit then impact sensing mechanism of the air bags get activated and launch the air bag.
However, there are no such mechanisms for fire safety which can mechanically stop the fuel supply of a car when it gets such hit or certain impact by using static inertia. Similarly, there are no such mechanisms for fire safety in an industrial application/operation consuming flammable fuel which can mechanically stop the supply of the fuel to such industrial application/operation when it subjected to certain impact due to natural calamity such as cyclonic storm, earthquake etc.
The inventor in a co-pending application WO2017006341 Al has disclosed an automatic liquid flow controlling device for stopping flow of the running liquid when the liquid flow exceeds a certain flow rate. But the reported liquid flow controlling device is not configured to stop flow of the running liquid depending on the impact applied on the device. Thus there has been a need for developing an impact sensitive non electrical mechanically operated fluid flow stopping system and method for stopping flow of a liquid medium/fluid running through a guiding means or fluid channel. The non electrical mechanical operation is an essential requirement as any electrical power driven flow stopping valve operation cannot be ensured during hit/impact.
OBJECT OF THE INVENTION:
It is thus the basic object of the present invention is to develop a system for stopping flow of fluid through a fluid channel depending on impact or shock applied on said system by any means. Another object of the present invention is to develop an impact activated system for stopping flow of the fluid through a fluid channel depending on impact or shock applied on the fluid channel.
Another object of the present invention is to develop a non electrical impact/shock/vibration activated mechanical system for automatically stopping flow of the fluid through a fluid channel upon receiving the impact/shock/vibration above permissible level.
Yet another object of the present invention is to develop a method for impact sensitive stopping flow of the fluid through a fluid channel depending on impact/shock/vibration applied on an impact sensing system cooperative to the fluid channel.
Another object of the present invention is to develop a method for impact sensitive stopping flow of the fluid through a fluid channel depending on impact/shock/vibration applied on the fluid channel.

DETAILED DESCRIPTION OF THE INVENTION WITH REFERENCE TO THE ACCOMPANYING DRAWINGS:
As stated hereinbefore, the present invention discloses an impact activated system for stopping flow of the fluid through a fluid channel depending on impact, vibration or shock applied on said system or the fluid channels connected to said system. The present impact activated system is configured to operate as an impact sensitive non-electrical mechanical valve for disposing in between the fluid channel to automatically stop the fluid flow through the fluid channel upon sensing any impact/vibration/shock in said impact activated system or in the fluid channel.
The impact activated fluid flow stopping system which is configured to operate as impact sensitive non-electrical mechanical valve essentially includes at least two elements, one is a magnetic means fixed to system housing and other one is a magnetically activated fluid blocker detachably secured with the magnetic fixed element in the system housing. The basic workable embodiment of the present impact activated fluid flow stopping system as shown in the figure l(i) includes a magnetically activated fluid blocking detachable element (c) which magnetically attached with the magnetic fixed element (b) accommodated within the system housing (a) . One of the detachable element (c) and the fixed element (b) is magnet or contain magnet (h) and other one is magnetic material, otherwise both of them can be magnet or contain magnet.
The fixed element (b) is attached with the system housing (a) and does not exhibit any movement when the system housing (a) and connected fluid channel are subjected to external impact/vibration/shock. The systems housing (a) can be connected in line with the fluid channel as mechanical valve wherein the fluid enters into the system from the incoming fluid channel (f) through inlet (d) of the system housing and proceeds towards the outgoing fluid channel (g) through system housing (a) and the outlet (e) of the system housing (a) till the system housing (a) and/or connected fluid channel are subjected to external impact/vibration/shock. The fluid flow path within the system is shown in the accompanying figure l(i) by using blue arrow. During acting of the impact/vibration/shock on the system housing (a) or connected fluid channel having magnitude greater than the magnetic force of attraction between the detachable element (c) and the fixed element (b), the detachable element (c) gets detached from the fixed element (b) due to static inertia as shown in the accompanying figure 1 (ii) .
The detached element (c) then moves towards the outlet (e) with the flow of the fluid and sits on the outlet (e) completely blocking the same. The detached element (c) gets arrested in the outlet (e) due to the pressure of the blocked fluid in the system housing applied on top of it and starts acting as a check valve closing the outlet (e) and stopping flow of the fluid to the outgoing fluid channel (g) as shown in the figure l(iii).
Reference is next invited from the accompanying figures 2a and 2b which show two preferred embodiments of the present impact activated system for stopping flow of the fluid through the fluid channel with fluid flow resuming provision. As shown in the referred figures, the present impact activated system ('S' indicated by the broken box) includes the detachable element (1) which is detachably secured with its conjugate fixed element (2) by magnetic force of attraction . Both the detachable element (1) and the conjugate fixed element (2) are enclosed by the system housing body (6) while the conjugate element (2) is operatively attached with the system housing body (6) under resilient bias.

As shown in the figures, the bypass fluid pipe ( 13) establishes a fluidic connection between the first chamber (I) and the outgoing fluid channel (10). The pressure relief valve (7) is provided on the bypass fluid pipe ( 13) to close or open the fluidic connection between the first chamber (I) and the outgoing fluid channel (10).
In a preferred embodiment of the present system, the washer (8) surrounding the outlet (12) is inclined towards the outlet to facilitate movement of the detached element (1) towards the outlet ( 12). The detachable element (1) is preferably round shaped for easy rolling on the washer (8) inclined surface. The conjugate fixed element (2) is preferably inverted shaped to hold the detachable element (1). In an alternate embodiment, both the detachable element ( 1) and the conjugate fixed element (2) may be circular plate wherein the detachable element (1) is smaller than the conjugate fixed element (2) to minimize the friction between the fluid and the detachable element ( 1) .
Reference is now invited from the accompanying figure 3a and figure 3b which show impact sensitive stopping of flow of the fluid through the fluid channel involving the present impact activated system with the fluid flow direction. As shown in the referred figures, during normal fluid flow motion, the compression spring (4) gets compressed due to pressure on the seal (5) applied by the fluid entering through the inlet. The compression of the spring (4) due to the fluid pressure on the washer or seal (5) push back the stem (8) further into the second chamber (II) which also move the conjugate fixed element (2) with the magnetically attached detachable element ( 1) towards the inclined washer (8) . In this configuration, the fluid entered into the first chamber (I) through the inlet ( 11) reach at the second chamber (II) through fluid passing holes defied in the separating member (15) and then finally moves to the outlet (12) as shown in the figure 3a (i) and 3b (i) using blue arrow.
Now, during acting of the impact on the system during fluid flow, the detachable element (1) gets detached from the conjugate fixed element (2) due to static inertia. The detached element (1) then drop on the washer (8), as shown in the figure 3a (ii) and 3b (ii). Due to the inclination in the washer (8) and flow of the fluid, the detached element ( 1) moves before the outlet ( 12) blocking the fluid to pass through said outlet (12) . The detached element (1) gets arrested on the washer (8) around the outlet (12) due to the pressure of the blocked fluid in the system housing body (I, II) and acts as check valve fully closing the outlet (12) which stops the flow of the fluid . This configuration is shown in the figure 3a (iii) and 3b (iii) .
After closing the outlet (12), the pressure developed in the blocked fluid within the system housing body also directs the conjugate fixed element (1) with the seal (5) and stem (3) to its original position closing the inlet ( 11), as shown in the figure 4e. Now to again open the outlet (12) and resume the flow of the fluid, the pressure relief valve (7) is opened which open the bypass fluid pipe (13) establishing the fluidic connection between the first chamber (I) and the outgoing fluid channel (10) . The blocked fluid within the system hosing body is thus passed to the outgoing fluid channel ( 10) through the bypass fluid pipe (13) which reduces the pressure developed in the blocked fluid. Due to the reduction of the pressure, the detached element (1) gets released from the washer (8) opening the outlet (12) for fluid flow, as shown in the figure 4 (fl). The released detached element (1) is then again magnetically attached with the conjugate fixed element (2) (as shown in the figure 4 (f2)) resetting the entire system in the configuration shown in the figure 4 (a) when the fluid flow in the incoming fluid channel is also stopped or in the figure 4 (b) when the fluid flow in the incoming fluid channel is still on. After resetting the entire system, the pressure relief valve (7) is closed which also close the bypass fluid pipe ( 13) disconnecting the fluidic connection between the first chamber (I) and the outgoing fluid channel ( 10) (as shown in figure 4 (a), (b)) .
While the present invention may have been described through reference to specific embodiments, the invention is not limited to these specific embodiments. Other changes and modifications known to those of ordinary skill are intended to be included within the scope of the present invention.
