: embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 2, a kind of large flow quantity intelligent caution type safety valve, it comprises that endoporus is equipped with the valve body attachment 17 of the floating plug 19 of through hole, black box 16, spool back-up ring 20, through screw thread, is connected with the spring strut 6 of outer surface coated with luminescent material.The outer upper end of spring strut 6 is provided with boss, under boss, along side ring face, is made as the initial reference line of pressure.In spring strut 6, establish Compress Spring 8, upper and lower end is respectively equipped with pressure adjusting nut 4 and floating spring seat 14.In Compress Spring circle 8, establish the threaded hollow connecting rod 3 of endoporus, in hollow connecting rod 3, be provided with the stroke that can move up and down and adjust sealing seat 9 and buffering sealing gasket 11.Stroke is adjusted sealing seat 9, and through cushion seal pad 11, the thrust by Compress Spring 8 is connected and seals with floating plug 19 upper end.Stroke adjustment sealing seat 9 through being threaded, moves up and down to adjust drainage locations and the stroke of floating plug 19 with hollow connecting rod 3 by left rotation and right rotation.The outer external screw-thread pipe support 10 that is provided with of spring strut 8, pipe support surface scribbles high-strength luminescent material, and be provided with guide chute, the pipe support capping 2 of screw thread, pressure scale line 21 and the memory wire loop circle 5 directed boss of installation reference line annular ring 7, through hollow connection spiral shell, 1 is threaded with hollow connecting rod 3, and realizes linkage from top to bottom with floating plug 19.External screw-thread pipe support 10 endoporus are provided with memory wire loop circle 5, and the directed boss that the upper end ring surface of memory wire loop circle 5 is provided with is memory line.External screw-thread pipe support 10 outsides are provided with tapped reference line annular ring 7, and reference line annular ring 7 upper end ring surfaces are made as pressure setting reference line.The variation length of the luminous surface by spring strut 8 and external screw-thread pipe support 10 outer surface different colours, can realize distant surveillance and warning support pressurized situation.By determining the position of reference line, memory line, dynamic line, contrast with pressure scale line 21, can the pressure of pillar, overload, leakage, impact condition be realized intelligent record and be analyzed.By being provided with the floating plug of a plurality of long trough relief holes 18 and through hole, can realize the requirement of large flow fast discharging of impacting with high pressure and moment.
Floating plug recited above (9) is through hole, and bottom is provided with a plurality of long trough relief holes (18) therein, and upper end is provided with boss, and boss axial end is made as circular arc, and lower end is provided with the spool back-up ring (20) being threaded.
The both sides of the memory wire loop circle 5 directed boss guide chutes that described external screw-thread pipe support 10 is provided with are respectively equipped with pressure scale and work highlight.
Described stroke is adjusted sealing seat 9 and is coordinated with the upper-end surface of cushion seal pad 11, floating plug 19, with solving high pressure quick earial drainage problem of moment.
Described memory wire loop circle 5 home positions are along limit, to be connected under the boss with spring strut 6 outer upper ends, and by elastic-friction, form interlock with external screw-thread pipe support 10, while moving to limit position on external screw-thread pipe support 10, memory wire loop circle 5 is subject to stopping along limit under the boss of spring strut 6 outer upper ends, produce relative sliding with external screw-thread pipe support 10, synchronize with spring strut 6, invariant position.When external screw-thread pipe support 10 moves down, memory wire loop circle 5 moves down thereupon.
Described pipe support capping 2 exterior edge faces are provided with a plurality of apertures with axle center symmetry, and the instrument of adjusting pressure adjusting nut 4 as rotation inserts.
Working procedure: be the initial dynamic line of pressure along side ring face under the boss of setting spring cylinder 6 outer upper ends, closely connected with memory wire loop circle 5 upper end ring surfaces is 0, by reference line annular ring 7 upper-end surfaces in accordance with regulations pressure move to the corresponding pressure position that external screw-thread pipe support 10 marks, now highly pressurised liquid enters in valve body attachment 17 cavitys by 17 times end entrances of valve body attachment, promote floating plug 9, cushion seal pad 11, stroke is adjusted sealing seat 9 and is driven hollow connecting rod 3 and floating spring seat 14, overcome the thrust of Compress Spring 8 and drive hollow connecting bolt 1, pipe support capping 2, on external screw-thread pipe support 10 and reference line annular ring 7, move.Memory wire loop circle 5 is stopped by spring strut 6 boss, closely connected invariant position.When reference line annular ring 7 upper-end surfaces move under the boss of spring strut 6 outer upper ends along 0 start line working area, below of the junction plane of side ring face and memory wire loop circle 5 upper end ring surfaces or when three lines overlap, stop fluid injection, now this valve has entered normal working.
When being subject to the effect of external force, when valve body attachment 17 cavity internal pressures are increased, promote floating plug 9 and move on again, while moving over black box 16 sealing station on long trough relief hole 18, highly pressurised liquid excretes through floating spring seat 14 lower end passages and outage 13.
If top board moment presses, long trough relief hole 18 is obstructed because impacting earial drainage, and now the sealing surface of cushion seal pad 11 and floating plug 9 is impacted by highly pressurised liquid to be opened, to realize large flow quick fluid-discharge.
When fluid pressure is less than safe opening pressure, safety valve cuts out automatically.
When fluid pressure reduces, memory wire loop circle 5, reference line annular ring 7 move down with external screw-thread pipe support 10, and memory wire loop circle 5 departs from 0 start line of spring strut 6 junction planes.
Below in conjunction with Fig. 3,4,5,6,7,8 aid illustration figure, the typical example shown in three's change in location state on edge under the boss of memory wire loop circle 5, reference line annular ring 7, spring strut 6 outer upper ends is briefly described.For ease of narration, spy marks above-mentioned each sideline in aid illustration figure with arrow.
Fig. 3. home position.Closely connected along limit under the boss of memory wire loop circle 5 and spring strut 6 outer upper ends, reference line annular ring 7 is in authorized pressure position.
Fig. 4. under the boss of memory wire loop circle 5 and spring strut 6 outer upper ends along limit closely connected and with the be separated by distance of regulation of reference line annular ring 7, illustrate working properlyly, equipment state is good.
Fig. 5. memory wire loop circle 5 departs under the boss of spring strut 6 outer upper ends along limit, and in reference line annular ring 7 tops, illustrate this valve during operation valve body internal pressure reduce, or cause because of leakage and other reason.
Fig. 6. closely connected or overlap with reference line annular ring 7 threes along limit under the boss of memory wire loop circle 5 and spring strut 6 outer upper ends, illustrate that pressure reaches safety valve enable possition.
Fig. 7. reference line annular ring 7 surpasses under the boss of memory wire loop circle 5 and spring strut 6 outer upper ends the position closely connected along limit, and pressure limit be described, and safety valve discharge opeing is obstructed, or safety valve inefficacy.
Fig. 8. memory wire loop circle 5 surpasses reference line annular ring 7, and with the boss of spring strut 6 outer upper ends under separated by a distance along limit, under the boss of reference line annular ring 7 in memory wire loop circle 5 and spring strut 6 outer upper ends, along neutral position, limit, the safety valve state that was subject to automatically to resume work again after impacting with high pressure is described.
Memory wire loop circle 5 adopts hand reset, rotation reference line annular ring 7 capable of regulating upper-lower positions.
