Description

TECHNICAL FIELD

[0001] The present application relates to a super flow valve applied to a fluid pipeline, in particular to a super flow valve locking stabilizing structure. BACKGROUND

[0002] Pipeline / piping system is one of the important equipment for transporting fluid, which can transport fluid from storage to the desired location. In addition to the common long tube in the pipeline system, fittings such as valve body, joint, etc. are also used. The valve body has various types, which can be selected according to the working purpose requirements, such as flow size, flow direction, flow or not, pressure control, etc.

[0003] Among the many valve bodies, the super flow valve is a valve that can be controlled by the pressure value set at the factory. When the fluid flowing through the super flow valve is greater than the pressure set value, the super flow valve will form a lock to limit the flow of fluid, play a safety protection role, and prevent fluid leakage, pressure vessel or pipeline damage, etc. to avoid larger accidents, etc.

[0004] However, in the pipeline / piping system, the pressure value of the end equipment of the pipeline is often insufficient compared to the pressure value of the remaining equipment, that is, the supply pressure is not equal. For example, in the natural gas pipeline of the same building, the closer to the end user of the pipeline, the lower the pressure value is often lower than that of the remaining users, so the same pressure value specification super flow valve cannot be used for end users, in other words, the same pressure value specification super flow valve cannot be applied to the entire pipeline. SUMMARY

[0005] The main technical problem to be solved by the present application is to overcome the above-mentioned defects existing in the prior art, and to provide a super flow valve locking stabilizing structure, which is applied to a fluid pipeline with lower pressure value than other equipment, can trigger locking under low fluid pressure to prevent fluid leakage and output accidents.

[0006] The technical scheme adopted by the present application to solve its technical problems is:

[0007] An ultraflow valve locking stabilizing structure, comprising a body, an adjusting assembly, a suspension system, wherein: the body comprises an inflow chamber, an outflow chamber and an operation chamber, the operation chamber is communicated with the inflow chamber and the outflow chamber respectively; an elastic ring is arranged between the operation chamber and the outflow chamber; the adjusting assembly is arranged in the body and communicated with the operation chamber; the suspension system is located in the operation chamber and controlled by the adjusting assembly, the suspension system comprises a first spring, a second spring and a locking body, the first spring and the second spring are connected with the locking body in opposite ways, the first spring abuts against the adjusting assembly, and the second spring abuts against the operation chamber, so that when the suspension system is in a normal position, the locking body does not contact the operation chamber and the elastic ring and is located outside the elastic ring; when fluid flows from the inflow chamber to the operation chamber, and the fluid pressure value is greater than the locking pressure value of the suspension system, the fluid pushes the locking body to move to close the elastic ring, at the same time, the locking body pulls the first spring and the second spring to deform, so that the suspension system is in a locking position, so that the operation chamber and the outflow chamber are closed by the locking body and the elastic ring and are not communicated with each other.

[0008] The application has the beneficial effect that it is applied to the fluid pipeline end pressure value which is lower than the pressure of other equipment, can trigger locking under the condition of low fluid pressure, so as to avoid the accident of fluid leakage output.

[0034] Please refer to Figures 1 to 4As shown in the figure, an overflow valve locking and stabilizing structure is disclosed, which includes a body 100, an adjustment assembly 200, and a suspension system 300. The body 100 includes an inflow chamber 110, an outflow chamber 120, and an operating chamber 130, with the operating chamber 130 connecting the inflow chamber 110 and the outflow chamber 120 respectively. An elastic ring 140 is provided between the operating chamber 130 and the outflow chamber 120. The adjustment assembly 200 is disposed within the body 100 and extends into the operating chamber 130. The suspension system 300 is located within the operating chamber 130 and controlled by the adjustment assembly 200. The suspension system 300 includes a first spring 310, a second spring 320, and a locking body 330, with the first spring 310 and the second spring 320 connected to the locking body 330 in opposite directions. 30, and the first spring 310 abuts against the adjusting assembly 200, while the second spring 320 abuts against the operating chamber 130, so that when the suspension system 300 is in the normal position, the locking body 330 does not contact the operating chamber 130 and the elastic ring 140 and is located outside the elastic ring 140; when fluid flows from the inflow chamber 110 to the operating chamber 130, and the fluid pressure value is greater than the locking pressure value of the suspension system 300, the fluid pushes the locking body 330 to move and close the elastic ring 140, and at the same time the locking body 330 pulls the first spring 310 and the second spring 320 to deform, so that the suspension system 300 is in the locked position, so that the operating chamber 130 and the outflow chamber 120 are closed by the locking body 330 in the elastic ring 140 and are not connected.

[0035] like Figure 3 As shown, supported by the first spring 310 and the second spring 320, the locking body 330 will not contact the wall of the operating chamber 130, nor will it contact the elastic ring 140, so that under normal flow and pressure, the fluid (as shown by the arrow in the figure) can enter the operating chamber 130 from the inflow chamber 110, and flow through the operating chamber 130 along the outside of the locking body 330 to the outflow chamber 120 for output.

[0036] like Figure 4 As shown, when the fluid flow rate or fluid pressure becomes abnormal, the fluid pushes the locking body 330 to move (as indicated by the arrow in the figure) and close the elastic ring 140, thereby preventing the fluid from flowing through the operating chamber 130 to the outflow chamber 120. When the locking body 330 moves to close the elastic ring 140, the first spring 310 and the second spring 320 connected to the locking body 330 are pulled and bent and deformed in the direction of the outflow chamber 120, and the aforementioned locking pressure value is the state in which the locking body 330 can pull the first spring 310 and the second spring 320 to deform.

[0037] The first spring 310 and the second spring 320 are respectively connected to the locking body 330 in two opposite directions, the first spring 310 provides upward support to the locking body 330, and the second spring 320 provides downward support to the locking body 330, so that the locking body 330 is in a suspended state in the operation chamber 130. This type of super flow valve is applied to the end of the pipeline with smaller flow pressure than other equipment, and can trigger the lock in abnormal flow pressure to achieve the safety protection mechanism.

[0038] Further details of the components of the present application and their assembly relationship are described. The adjustment assembly 200 includes an adjustment seat 210, a return shaft 220, a pressure cap 230, an adjustment shaft 240, and a support spring 250. The adjustment seat 210 is assembled in the body 100. One end of the return shaft 220 is a return head section 221 movably penetrating the adjustment seat 210 towards the operation chamber 130, and the other end of the return shaft 220 is outside the adjustment seat 210 and is fixed by the pressure cap 230. The support spring 250 is penetrated by the return shaft 220, and the two ends of the support spring 250 are respectively elastically abutted between the pressure cap 230 and the adjustment seat 210. The adjustment shaft 240 penetrates the return shaft 220, and part of the adjustment shaft 240 is screwed into the inside of the return shaft 220, and one end of the adjustment shaft 240 has a abutting groove 241 for abutting the first spring 310, and the other end of the adjustment shaft 240 has a driving groove 242.

[0039] Please refer to Figure 5 When the fluid flow or fluid pressure is abnormal, the pressure cap 230 can be manually pressed to disengage the locking body 330 from the elastic ring 140, and the locking body 330 is reset by the elastic recovery of the first spring 310 and the second spring 320, so that the locking body 330 no longer closes the elastic ring 140, thereby releasing the locking of the suspension system 300 and restoring the flow operation mode of the super flow valve. After removing the external force applied to the pressure cap 230, the adjustment assembly 200 can reset the return shaft 220 and the adjustment shaft 240 with the pressure cap 230 by the support spring 250 abutting the pressure cap 230.

[0040] As Figure 6As shown, a tool (not shown) can be used to abut the driving groove 242 of the adjustment shaft 240 and drive the adjustment shaft 240 to rotate, so that the adjustment shaft 240 is displaced relative to the axial direction of the return shaft 220 and toward the operation chamber 130, thereby compressing the first spring 310 and the second spring 320 to adjust the preload of the first spring 310 and the second spring 320. By adjusting the preload as described above, the force of the first spring 310 and the second spring 320 resisting displacement of the locking body 330 can be changed, so that the pressure of the fluid line corresponding to the superflow valve can be changed, and the larger pressure fluid can flow through the body 100.

[0041] The locking body 330 is generally spherical; the first protruding column 331 and the second protruding column 332 are respectively protruded on the opposite surfaces of the locking body 330; the first spring 310 is connected to the first protruding column 331, and the second spring 320 is connected to the second protruding column 332. The first spring 310 and the second spring 320 have similar shapes; the second spring 320 is more easily deformed under force than the first spring 310, that is, the spring constant of the second spring 320 is smaller than the spring constant of the first spring 310, so that under the same external force, the compression deformation of the second spring 320 is greater than the compression deformation of the first spring 310; the first spring 310 includes a narrow diameter section 311 and a wide diameter section 312, and the narrow diameter section 311 and the wide diameter section 312 are connected to each other; the narrow diameter section 311 of the first spring 310 is positioned at the first protruding column 331, and the wide diameter section 312 of the first spring 310 abuts against the adjustment assembly 200; the second spring 320 includes a narrow diameter section 321 and a wide diameter section 322, and the narrow diameter section 321 and the wide diameter section 322 are connected to each other; the narrow diameter section 321 of the second spring 320 is positioned at the second protruding column 332, and the wide diameter section 322 of the second spring 320 abuts against the operation chamber 130. The narrow diameter sections 311 and 321 are both equal-diameter types. The wide diameter sections 312 and 322 are non-equal-diameter types, and the wide diameter sections 312 and 322 are tapered non-equal-diameter types connected to the narrow diameter sections 311 and 321, respectively.

[0042] In addition, please refer to Figure 2 、 Figure 3 、 Figure 7As shown, the first protruding post 331 has a first annular groove 333 formed on the inner surface of the outer surface of the first protruding post 331, and the second protruding post 332 has a second annular groove 334 formed on the inner surface of the outer surface of the second protruding post 332. The first spring 310 is partially sleeved and accommodated in the first annular groove 333 of the first protruding post 331 by the narrow-diameter section 311, and the second spring 320 is partially sleeved and accommodated in the second annular groove 334 of the second protruding post 332 by the narrow-diameter section 321. Thus, the narrow-diameter section 311 of the first spring 310 is accommodated in the first annular groove 333, and the narrow-diameter section 321 of the second spring 320 is accommodated in the second annular groove 334, so that the first spring 310 is not easily separated from the first protruding post 331, and the second spring 320 is not easily separated from the second protruding post 332, thereby achieving the stable positioning of the first spring 310 and the second spring 320 in the first protruding post 331 and the second protruding post 332, respectively.

[0043] Please refer to Figure 3 As shown, the adjustment seat 210 has an outwardly protruding outer annular rib 211, the adjustment seat 210 is sleeved with the leak-proof gasket 260 and abuts between the outer annular rib 211 and the threaded hole 150 of the body 100, and the outer annular rib 211 of the adjustment seat 210 is partially pressed against the outer edge of the threaded hole 150, so that the leak-proof gasket 260 is not exposed outside the body 100. Through the cooperation of the outer annular rib 211 of the adjustment seat 210 and the leak-proof gasket 260, the overflow of fluid from between the threaded hole 150 and the adjustment seat 210 can be effectively prevented, and the abutting of the outer annular rib 211 against the outer edge of the threaded hole 150 (the outer surface of the body 100) limits the rotation of the adjustment seat 210 relative to the threaded hole 150 to avoid exceeding the default position, and the outer annular rib 211 can press against the leak-proof gasket 260 to retain a moderate deformation amount, thereby achieving a better sealing effect.

[0044] The inflow chamber 110 is sleeved with an inflow annular groove 111 and is close to the operation chamber 130, and the buckle 112 and the filter screen 113 are positioned in the inflow annular groove 111 together; and the filter screen 113 is closer to the operation chamber 130 than the buckle 112. By intercepting foreign matter by the filter screen 113, the foreign matter other than fluid can be prevented from entering the operation chamber 130 to hinder the operation of the suspension system 300.

[0045] The operation chamber 130 and the outflow chamber 120 are provided with an outflow hole 160, the elastic ring 140 includes a fixed section 141 and a deformed section 142 and is connected with each other, and the elastic ring 140 is positioned in the outflow hole 160 by the fixed section 141, and the deformed section 142 of the elastic ring 140 extends outside the outflow hole 160 and is positioned in the operation chamber 130; when the fluid pushes the locking body 330 to move to close the deformed section 142 of the elastic ring 140, the deformed section 142 of the elastic ring 140 has a slightly outward deformation characteristic under force, so that when the locking body 330 moves to close the deformed section 142, the opening of the deformed section 142 is slightly expanded under the action of the locking body 330, so that the spherical surface of the locking body 330 is more closely attached to the inside of the opening of the deformed section 142.

[0046] Please refer to Figure 8 、 Figure 9 , which is another embodiment of the present application, which is different from the above-mentioned embodiment, and the difference is that the locking body 330 is provided with a first groove 335 and a second groove 336 on the opposite surfaces thereof. The first spring 310 is connected to the first groove 335, and the second spring 320 is connected to the second groove 336. The narrow section 311 of the first spring 310 is positioned in the first groove 335, and the narrow section 321 of the second spring 320 is positioned in the second groove 336.

[0047] The first groove 335 has a groove section 337 close to the central position of the locking body 300, and the narrow section 311 of the first spring 310 is positioned in the groove section 337 of the first groove 335. The second groove 336 has a groove section 338 close to the central position of the locking body 300, and the narrow section 321 of the second spring 320 is positioned in the groove section 338 of the second groove 336.

[0048] The above-mentioned is only the preferred embodiment of the present application, and does not limit the present application in any form. Any simple modification, equivalent change and modification of the above-mentioned embodiment according to the technical essence of the present application still belongs to the scope of the technical solution of the present application.
