Description

Magnetronic Fluid Interrupter

The invention relates to a magnetically controlled fluid interrupter applied to fluid pipelines.

Pipeline/piping system is one of the important equipment used to transport fluid, which can transport fluid from storage to desired destination. In addition to the common long pipes, valve bodies, joints and other accessories are also used in the piping system. There are many types of valve bodies mentioned above, and the types of flow rate, flow direction, flow or not, and pressure control can be selected according to work requirements.

Among the many valve bodies, there is one that can be locked and controlled according to the pressure value set by the factory, such as overflow valve and shut-off valve. When the pressure of the fluid flowing through the aforementioned valve body is greater than the aforementioned pressure setting value, the valve body will form a block, block and restrict the flow of fluid, and open the safety protection function to prevent fluid leakage, damage to pressure vessels or pipelines, etc. utility, so as not to expand into a larger accidental disaster.

The aforementioned valve body is, for example, Taiwan Invention Patent No. I609145 "Fluid Safety Breaker". In this case, a spring is used to push the ball on the wall groove. The fluid will flow through the spring under normal flow conditions, and the fluid will push the ball away when a large flow occurs. The wall groove closes the output hole. The spring will be bent and deformed during the displacement of the ball. When the ball returns, it can be reset by the spring. However, in the way of pushing the ball with the elastic force of the spring, since the spring is located on the path of the fluid flow, the spring will affect the flow of the fluid. Furthermore, the structural design of the spring itself has the characteristics of being stretched, and when the external force is removed, it can rely on its own elastic reset characteristics, so that when the aforementioned fluid pushes the displacement of the ball to drive the spring to bend, there will still be the force of the spring pulling the ball. As a result, the ball cannot completely seal the output hole, causing a slight leakage of fluid from the output hole. Especially when the fluid pushes the displacement of the ball to drive the spring to bend and deform, the spring parts at the bend are close to each other and driven by the fluid, it is easy to entangle, so that it will not be sealed in the future due to the spring entanglement factor. The output hole must be dismantled, inspected, maintained or replaced by the relevant equipment personnel on a regular basis, so the above-mentioned valve body still has its risks and dangers in actual use.

In order to solve the above technical problems, the main purpose of the present invention is to provide a housing that does not use springs to avoid directly affecting the flow of fluid, and at the same time avoids the impact of the elastic force of the spring on the sealing effect during locking.

In order to achieve the foregoing object effect, the present invention adopts the following technical solutions:

A magnetically controlled fluid interrupter, which includes a body and a blocking component, wherein: the body includes an inflow groove, an outflow groove, and an operation groove, and the operation groove communicates with the inflow groove and the outflow groove respectively; An elastic ring is arranged between the outflow grooves; the blocking assembly is arranged on the body and leads to the operation groove, the blocking assembly includes an active part and a blocking body, and the blocking body and the active part are in between Magnetic attraction, so that the blocking body does not touch the operating groove in the operating groove and keeps a distance from the elastic ring, so that the magnetic control fluid interrupter is in a flow state; when the fluid flows through the inflow groove to the operating groove When the fluid flow velocity is greater than the magnetic attraction between the blocking body and the active part, the fluid pushes the blocking body to displace, so that the operating groove and the outflow groove are closed by the blocking body in the elastic ring to form a mutual relationship. Not connected, so that the magnetic control fluid interrupter is in a locked state.

The beneficial effect of the magnetic control fluid interrupter of the present invention is that in actual use, the main body can be connected to the pipeline through the inflow groove and the outflow groove, so as to provide a storage place and transport it to the position of the required device. When the fluid is in a normal flow rate (flow rate), the fluid enters the operating groove from the inflow groove, and flows out through the operating groove along the peripheral side of the interrupter body to the outflow groove, so that the magnetically controlled fluid interrupter is in a flow state, and the above process is interrupted. Both the disconnecting body and the active part maintain magnetic attraction and do not fall off, so the blocking body does not contact the operating groove and the elastic ring, and keeps a distance from the elastic ring to provide fluid flow. When the fluid flow or fluid velocity is abnormal, and the force exerted by the fluid on the blocking body is greater than the magnetic attraction force of the blocking body and the active part, the fluid can push the blocking body to displace, making the operation The groove and the outflow groove are closed by the blocking body on the elastic ring and are not connected to each other, so that the magnetic control fluid interrupter is in a closed state, so that the inflow groove and the outflow groove are closed by the blocking body in an elastic state. The circle is in a disconnected state. Thus, based on the above description, under the novel structural design of the fluid of the present invention, the problems caused by the use of springs in the past can indeed be avoided.

The groove 230 does not contact the operation groove 230 and keeps a distance from the elastic ring 240, so that the magnetron fluid interrupter 100 is in a flow state; When the breaking body 400 and the active part 301 are magnetically attracted, the fluid pushes the blocking body 400 to displace, so that the operation groove 230 and the outflow groove 220 are closed by the blocking body 400 on the elastic ring 240 to form a are not connected with each other, so that the magnetic control fluid interrupter 100 is in a locked state.

In actual use, the main body 200 can be connected to the pipeline through the inflow groove 210 and the outflow groove 220 to provide a storage place and transport it to a desired device location. When the fluid is in a normal flow rate (flow rate), the fluid enters the operation groove 230 from the inflow groove 210, and flows through the operation groove 230 along the outer peripheral side of the blocking body 400 to the outflow groove 220, so that the magnetic control fluid circuit breaker 100 is in a flow state. , and in the above process, both the blocking body 400 and the active part 301 maintain magnetic attraction and the blocking body 400 does not fall off, so the blocking body 400 does not contact the operation groove 230 and the elastic ring 240, and remains with the elastic ring 240 The spacers provide fluid flow. When the fluid flow rate or fluid velocity is abnormal and the force exerted by the fluid on the blocking body 400 is greater than the magnetic attraction force of the blocking body 400 and the active part 301, the fluid can push the blocking body 400 to move , so that the operation groove 230 and the outflow groove 220 are closed by the blocking body 400 on the elastic ring 240 and are not connected to each other, so that the magnetic control fluid interrupter 100 is in a closed state, so that the inflow groove 210 and the outflow groove The interrupted body 400 is closed by the elastic ring 240 between the slots 220 so as to be in a disconnected state.
