Description

Magnetic control fluid breaker

Technical Field

The utility model relates to a magnetic control fluid breaker applied to a fluid pipeline.

Background

Piping/tubing is one of the important devices used to transport fluids from storage to a desired destination. Besides the common long pipe, the pipeline system also uses fittings such as valve body, joint, etc. The valve body has various types, and the types of flow quantity, flow direction, flow condition, pressure control and the like can be selected according to working requirements.

One of the valve bodies can be locked and controlled according to a pressure value set by a factory, such as an overflow valve and an interruption valve. When the pressure of the fluid flowing through the valve body is larger than the pressure set value, the valve body can form locking and blocking to limit the fluid circulation, and the safety protection effect is opened, so that the effects of preventing the fluid from leaking, preventing the damage condition of a pressure container or a pipeline and the like are achieved, and the larger accidental disasters are avoided.

The valve body, for example, in taiwan patent No. I609145, "fluid safety breaker", uses a spring to push the ball to the wall groove, the fluid will flow through the spring under normal flow rate, and when large flow rate occurs, the fluid pushes the ball to leave the wall groove to close the output hole, the ball will be driven to bend and deform during displacement, and the ball can be pulled to reset by the spring when returning. However, in the way that the elastic force of the spring pushes the ball, the spring influences the flow of the fluid because the spring is located on the path of the fluid flow. Moreover, the spring itself is designed to have a stretched state, and when the external force is removed, the spring can be reset by the elastic force of the spring itself, so that when the fluid pushes the ball to move and drive the spring to bend, the acting force of the spring pulling the ball still exists, so that the ball cannot completely seal the output hole, and the problem of slight leakage of the fluid from the output hole is caused. Especially, when the fluid pushes the displacement of the ball to drive the spring to bend and deform, the spring parts at the bending part are mutually close to each other and are pushed by the fluid, so that the entanglement phenomenon is easy to occur, the output hole cannot be sealed completely due to the spring entanglement factor in future use, and related equipment personnel must be detached, inspected, maintained or replaced regularly, so that the valve body still has risks and dangerousness in actual use.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to overcome the above-mentioned drawbacks of the prior art, and provides a magnetic control fluid interrupter, which can avoid the influence of the spring force of the spring on the sealing effect during closing, in addition to avoiding the direct influence on the flow of the fluid without using the spring.

The technical scheme adopted by the utility model for solving the technical problems is as follows:

a magnetic control fluid breaker comprises a body and a breaker component, wherein: the body comprises an inflow groove, an outflow groove and operation grooves, and the operation grooves are respectively communicated with the inflow groove and the outflow groove; an elastic ring is arranged between the operation groove and the outflow groove; the interceptor assembly is arranged on the body and communicated with the operation groove, and comprises an action part and an interceptor body, wherein the interceptor body and the action part are magnetically attracted, so that the interceptor body is not contacted with the operation groove in the operation groove and keeps a gap with the elastic ring, and the magnetic control fluid interceptor is in a circulation state; when the flow rate of the fluid flowing to the operation groove through the inflow groove is larger than the magnetic attraction of the blocking body and the action part, the fluid pushes the blocking body to displace, so that the operation groove and the outflow groove are not communicated with each other because the blocking body is sealed on the elastic ring, and the magnetic control fluid breaker is in a blocking state.

The utility model has the beneficial effect that when in actual use, the body is connected with the pipeline through the inflow groove and the outflow groove, and the storage position is provided for conveying to the position of the required device. When the fluid is in normal flow (flow speed), the fluid enters the operation groove from the inflow groove and flows to the outflow groove through the operation groove along the outer peripheral side of the breaker body to be output, so that the magnetic control fluid breaker is in a circulation state, and the breaker body and the action part keep magnetic attraction and do not fall off in the process, therefore, the breaker body does not contact with the operation groove and the elastic ring and keeps a gap with the elastic ring to provide fluid flow. When the abnormal condition of fluid flow or fluid flow rate occurs, the acting force applied to the breaker by the fluid is larger than the magnetic attraction acting force of the breaker and the acting part, the fluid can push the breaker to displace, so that the operation groove and the outflow groove are not communicated with each other because the breaker is sealed in the elastic ring, and the magnetic control fluid breaker is in a locked state, so that the inflow groove and the outflow groove are not communicated with each other because the breaker is sealed in the elastic ring. Thus, with the above-mentioned description, the problems caused by the past use of springs can be avoided with the novel fluid structure design of the present invention.

Detailed Description

Referring to fig. 1 to 4, a magnetic control fluid interrupter 100 is disclosed, which includes a body 200 and an interrupter assembly 300, wherein: the body 200 comprises an inlet slot 210, an outlet slot 220 and an operation slot 230, wherein the operation slot 230 is respectively communicated with the inlet slot 210 and the outlet slot 220; an elastic ring 240 is disposed between the operation groove 230 and the outflow groove 220; the interrupter assembly 300 is disposed on the body 200 and connected to the operation tank 230, the interrupter assembly 300 includes an action portion 301 and an interrupter body 400, and the magnetic attraction between the interrupter body 400 and the action portion 301 causes the interrupter body 400 to be in the operation tank 230 without contacting the operation tank 230 and keep a gap with the elastic ring 240, so that the magnetic control fluid interrupter 100 is in a flowing state; when the fluid flowing into the operation tank 230 through the inflow tank 210 has a flow rate greater than the magnetic attraction between the blocking member 400 and the action portion 301, the fluid pushes the blocking member 400 to displace, so that the operation tank 230 and the outflow tank 220 are not connected to each other by the elastic ring 240 enclosed by the blocking member 400, and the magnetic control fluid interrupter 100 is in a blocked state.

In actual use, the body 200 is connected to a pipeline through the inlet groove 210 and the outlet groove 220 to provide a storage place for delivering to a desired device. When the fluid is at a normal flow rate (flow velocity), the fluid enters the operation groove 230 from the inflow groove 210, and flows to the outflow groove 220 through the operation groove 230 along the outer circumferential side of the blocking body 400 to be output, so that the magnetron fluid interrupter 100 is in a flowing state, and in the above process, the blocking body 400 and the action part 301 keep magnetic attraction, but the blocking body 400 does not fall off, so that the blocking body 400 does not contact with the operation groove 230 and the elastic ring 240, and keeps a gap with the elastic ring 240 to provide fluid flow. When the fluid flow or the fluid flow rate is abnormal, and the acting force applied to the blocking element 400 by the fluid is greater than the magnetic attraction acting force of the blocking element 400 and the acting portion 301, the fluid can push the blocking element 400 to displace, so that the operating slot 230 and the outflow slot 220 are not communicated with each other because the blocking element 400 is sealed by the elastic ring 240, and the magnetic control fluid interrupter 100 is in a closed state, so that the blocking element 400 is sealed by the elastic ring 240 between the inflow slot 210 and the outflow slot 220 and is not communicated with each other. Thus, with the above-mentioned structure design, the problem caused by the past use of the spring can be avoided.

Referring to fig. 1 to 6, in the present embodiment, specifically, the acting portion 301 is a block magnet. The blocking assembly 300 includes an adjusting seat 310, an outer tube 320, a pressing cap 330, a supporting spring 340 and an adjusting shaft 350, wherein: the adjusting seat 310 is assembled on the main body 200; one end of the outer tube 320 is a head 321 movably passing through the adjusting seat 310 and facing the operating slot 230, and the other end of the outer tube 320 is located outside the adjusting seat 310 and fixed by the pressing cap 330; the supporting spring 340 is inserted through the outer tube 320, and two ends of the supporting spring 340 respectively elastically support between the pressing cap 330 and the adjusting base 310; the adjusting shaft 350 penetrates through the outer tube 320, and part of the adjusting shaft 350 is screwed into the outer tube 320, one end of the adjusting shaft 350 close to the pressing cap 330 is provided with a driving groove 351, and the other end of the adjusting shaft 350 is provided with the acting part 301 and is positioned inside the head section 321 without being exposed, so that the blocking body 400 contacts with the end surface of the head section 321; the driving groove 351 of the adjusting shaft 350 is applied with a force and drives the adjusting shaft 350 to rotate, so that the adjusting shaft 350 is displaced towards the operating groove 230 relative to the axial direction of the outer tube 320, and the acting portion 301 is never contacted with the shielding body 400 and synchronously displaced, thereby changing the distance between the shielding body 400 and the elastic ring 240. The action part 301 is a block magnet, so that the adjusting shaft 350 can be made of two different material parts, and can be fixed and combined into a whole by means of adhesion, embedding and the like, so that the adjusting shaft 350 can be made and combined by two components, and the processing, manufacturing and combination of the components are convenient for manufacturers.

Referring to fig. 5, after the abnormal release of the fluid flow or the fluid flow rate occurs, the pressing cap 330 may be continuously pressed by hand, so that the pressing cap 330 synchronously drives the outer tube 320 and the adjusting shaft 350 to displace along the axial direction of the adjusting seat 310 and toward the operation slot 230, so that the acting portion 301 pushes the blocking body 400 to separate from the elastic ring 240, and the acting portion 301 magnetically adsorbs the blocking body 400, so that the blocking body 400 no longer seals the elastic ring 240, thereby releasing the blocking state of the magnetic control fluid interrupter 100 and restoring to the circulation state.

The driving groove 351 of the adjusting shaft 350 can be abutted by a tool to drive the adjusting shaft 350 to rotate, so that the adjusting shaft 350 is displaced towards the operation groove 230 relative to the axial direction of the outer tube 320, thereby changing the position of the blocking body 400 relative to the elastic ring 240, and changing the flow rate of the fluid correspondingly used by the magnetic control fluid interrupter 100.

In this embodiment, the adjusting seat 310 has an outer annular rib 311 protruding outward, the adjusting seat 310 is sleeved with a leakage-proof washer 312 and abuts between the outer annular rib 311 and the threaded hole 250 of the body 200, and the outer annular rib 311 of the adjusting seat 310 is partially pressed against the hole outer edge of the threaded hole 250, so that the leakage-proof washer 312 is not exposed outside the body 200. By the cooperation of the outer ring rib 311 of the adjusting seat 310 and the anti-leakage washer 312, the fluid can be effectively prevented from overflowing from between the threaded hole 250 and the adjusting seat 310, and the outer ring rib 311 abuts against the outer edge of the threaded hole 250 (the outer side surface of the body 200), so that the adjusting seat 310 is prevented from rotating relative to the threaded hole 250 to exceed a default position, and the outer ring rib 311 presses against the anti-leakage washer 312 to maintain a proper deformation amount, thereby achieving a better sealing effect.

In this embodiment, the inflow groove 210 is surrounded by an inflow ring groove 211 and is close to the direction of the operation groove 230, and a retaining ring 261 is positioned in the inflow ring groove 211 together with the periphery of the filter screen 262; and the filter 262 is closer to the operating tank 230 than the retaining ring 261. The filter 262 is used to intercept foreign matters, so as to prevent foreign matters other than fluid from entering the operation groove 230 to obstruct the operation of the shutoff assembly 300.

In this embodiment, an outflow hole 270 is disposed between the operation slot 230 and the outflow slot 220, the elastic ring 240 includes a fixing section 241 and a deforming section 242, and they are connected to each other, the elastic ring 240 is positioned in the outflow hole 270 by the fixing section 241, and the deforming section 242 of the elastic ring 240 extends out of the outflow hole 270 and is positioned in the operation slot 230; when the fluid pushes the blocking element 400 to close the deformation section 242 of the elastic ring 240, the elastic ring 240 has a slightly expandable deformation characteristic under a force by virtue of the deformation section 242, so that when the blocking element 400 moves to close the deformation section 242, the opening of the deformation section 242 is slightly expanded under the action of the blocking element 400, so that the spherical surface of the blocking element 400 is more tightly attached to the inner side of the opening of the deformation section 242.

Referring to fig. 7 to 10, a second embodiment of the magnetic fluid interrupter 100 according to the present invention is different from the above embodiments in that the acting portion 301 is a rod-shaped magnet. The actuating portion 301 is disposed on the adjusting shaft 350 from one end of the driving groove 351 to the other end thereof, so that the blocking member 400 contacts the end surface of the head 321. In other words, the adjusting shaft 350 is entirely constructed by using magnets, and the shielding member 400 can be magnetically attracted by the end of the adjusting shaft 350 opposite to the driving groove 351.

Referring to fig. 11 to 14, a third embodiment of the magnetic controlled fluid interrupter 100 of the present invention is different from the first embodiment in that the interrupter 400 is a ball magnet.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications, equivalent variations and modifications made to the above embodiment according to the technical spirit of the present invention still fall within the scope of the technical solution of the present invention.
