2, built-up welding has wear-resisting hardened layer on the arc surface of the utility model valve rod lower end, has increased the intensity of valve rod like this, reduces and scraps and service cycle, reduces cost, and prolongs its working life.
3, be provided with locking nut between the utility model screw rod and the supporting disk, be convenient to determine the pretightening force of spring, its Security is good.
4, reasonable in design, the satisfactory mechanical property of the utility model, sealing are reliable, simple in structure, are applicable to the high-temperature molten salt medium break-make of aluminium manufacturer's fused salt pipeline, are easy to promote, and economic benefit is good.
Four. description of drawings:
Fig. 1 is the structural representation that is used for the high temperature resistant Y type safety relief valve of aluminium manufacturer's fused salt pipeline.
Five. embodiment:
Embodiment: referring to Fig. 1, among the figure, 1-valve body, 2-valve seat, the 3-flap, 4-ball, 5-stud, 6-nut, the 7-valve gap, 8-nut, 9-valve rod, 10-strut, the 11-spring seat, 12-spring, 13-screw rod, 14-supporting disk, the 15-handwheel, 16-locking nut, 17-nut, 18-stud, the 19-Gland, 20-filler, 21-pad.
The high temperature resistant Y type safety relief valve that is used for aluminium manufacturer's fused salt pipeline comprises valve body 1, valve gap 7 and valve rod 9, the import of valve body 1, outlet and inner chamber three are y-type structure, its inlet is welded with valve seat 2, valve seat 2 is provided with flap 3, valve rod 9 is sleeved in the endoporus of a guide sleeve, be provided with sealing mechanism between the two, the underpart of valve rod 9 directly contacts with the circular-arc bottom face of flap 3 upper end center holes, guide sleeve is fixed in the center hole of valve gap 7, a fixed tray is fixed in the guide sleeve upper end, this fixed tray is connected with the lower end of two struts 10, the upper end of two struts 10 is connected with a supporting disk 14, the two ends that suit is set with 12, two springs 12 of a spring up and down on 11, two struts 10 of two spring seats on two struts 14 respectively with two spring seat 11 clampings up and down, lower spring cup 11 and valve rod 9 upper end clampings, the lower end clamping of upper spring seat 11 and screw rod 13, screw rod 13 is threaded with the center hole of supporting disk 14, and the upper end portion of screw rod 13 is equipped with handwheel 15.
Valve rod 9 lower end surfaces are arc surface, and in order to gain in strength, built-up welding has wear-resisting hardened layer on this arc surface.Be provided with locking nut 16 between screw rod 13 and the supporting disk 14.Be provided with gasket seal 21 between valve gap 7 and the valve body 1.
Sealing mechanism is filler 20 and Gland 19 formula structures; Last lower spring cup 11 is provided with locating column or setting sleeve, and the two ends of spring 12 are set on locating column or the setting sleeve, two struts 10 be uniformly distributed along the circumference and the specification of two springs 12 identical, thereby pretightening force evenly distributes.As required, strut 10 also can adopt three or four uniform settings.
Valve body 1 is a weldment, valve seat 2, inlet connection, discharge connection are welded on the valve body relevant position respectively, be processed with groove with valve rod 9 lower ends in flap 3 upper end holes, ball 4 is installed in the groove, and seal with Cock screw, can make flap 3 be unlikely to come off, can make flap 3 that the small number of activity gap is arranged again from valve rod 9 ends.Valve gap 7 is a weldment, utilize flange to be connected with valve body 1, gasket seal 21 is arranged between the two, and with stud 5 and nut 6 pretensions, stud 18 and nut 17 compress Gland 19, open and during discharging at safety valve like this, more than the pad 21 and the filler 20 at two positions can effectively prevent leaking outside of safety valve.Strut 11 is fixed on the valve gap 7, is used for supported spring and upper parts.
By tightening or loosening handwheel 15 carries out pressure setting, adjust finish after locking locking nut 16, thereby prevent that screw rod 13 is loosening and change Set pressure.This moment, length of spring compressed power acted on the valve rod 9 by spring seat 11, reached on the flap 3 again, and flap 3 sealing surface compact produce sealing force on valve seat 2 sealing surfaces, guarantee the sealing of safety valve Decompression valves.The valve body chamber separates fully with spring 12, and spring 12 does not seal fully, and spring 12 directly contacts atmosphere.
Pressure medium is increased to specified value when the ingress, and promptly during Set pressure, medium upwards acts on the downward compressive force balance that power on the flap 3 and spring 12 produce, and this moment, sealing force was zero, and medium begins to be released by sealing vice division chief.When pressure medium continued to be elevated to discharge pressure, flap 3 standard-sized sheets reached the Lift of regulation, and medium releases from valve seat 2 spouts, thus the safety of protection pressure system.When pressure medium owing to releasing of safety valve Decompression valves drops to certain value, promptly during Reseating pressure of a safety valve, the safety valve Decompression valves returns seat and sealing automatically, guarantees the normal operation of equipment.
By the high-temperature molten salt medium of being released, enter outlet conduit from the safety valve outlet, can contact spring, the spring temperature can not rise De Taigao yet, and has influence on the performance of safety relief valve, thus the operation of the normal safety of assurance equipment.
The concrete structure and quantity, the specific constructive form of change ball and the concrete mode of change sealing mechanism that change strut can be formed a plurality of embodiments, are common variation of the present utility model, do not describe in detail one by one at this.
