Background technique
The function of tradition stop valve is cut-off or connects ducted medium; The function of throttle valve is to block or connect ducted medium, plays adjust flux; The function of safety check is that control media flows backwards.In order to reduce cost of electricity-generating, improve generating efficiency, power generating equipment is just towards the future development of maximization, high parameter, high-performance, multi-purpose valve, multi-purpose valve, frequency of utilization is higher, and valve sealing face easily weares and teares.
Summary of the invention
In order to address the above problem, the utility model proposes the hard seal ring multiaction of a kind of supercritical, high pressure power valve, valve mainly adopts high pressure, hard self sealing structure, valve seat is detachable, easy to maintenance, solves multi-purpose valve structure, meets applying working condition.
In order to reach foregoing invention object, the utility model proposes following technological scheme:
The hard seal ring multiaction of supercritical, high pressure power valve, it comprises valve body, flap, thrust plate, valve clack cover, valve rod, pressure sealing ring, Stuffing box, support, pad, gland nut, spacer ring, fixing pin, filler, gland, pressing plate, gear drive, valve seat, flap is contained in the middle of valve body, between valve body and flap, valve seat is housed, flap upper end connects valve rod, between valve rod and flap, thrust plate is housed, valve clack cover is housed in flap upper end and valve clack cover is enclosed within valve rod lower end, Stuffing box is equipped with in inside, valve body upper end, between Stuffing box and valve body, pressure sealing ring is housed, support is equipped with in Stuffing box upper end, support is arranged on valve body upper end, support upper end is rotary with gland nut, between gland nut and support, pad is housed, filler and spacer ring are housed in Stuffing box, filler and spacer ring are enclosed within outside valve rod, spacer ring is contained in the middle of filler, above filler, be pressed with gland, above gland, be pressed with pressing plate, pressing plate is fixed on support by eye bolt and nut, eye bolt lower end is connected on support by fixing pin, valve rod upper end is connected with gear drive, gear drive is fixed by screws in support upper end.
The working pressure of the described hard seal ring multiaction of supercritical, high pressure power valve is below 42MPa.
Described valve seat is detachable valve seat.
Sealing surface on the flap of the described hard seal ring multiaction of supercritical, high pressure power valve is that built-up welding STL cemented carbide is made.
Described pressure sealing ring is hard seal ring.
The effect that the utility model has the advantages that former valve clack cover is valve rod and being connected of flap, and now changes into flap and being connected, and only valve rod is play the guiding role; Former valve seat welds on valve body, and bad dismounting now changes detachable valve seat into, easy to maintenance; Stop valve, throttle valve when medium enters from low groove; Safety check when medium enters from high groove, multi-purpose valve way; Pressure sealing ring: be originally soft seal, existing is hard sealing; Sealing surface weld deposit cemented carbide, has improved corrosion resistance and the wear resistance of valve, has extended the working life of valve.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
