Abstract
The utility model relates to a high-temperature and high-pressure temperature and pressure relief valve, which comprises an electric actuator, a valve stem, a valve body, a support, a valve bonnet, a valve clack, a nozzle and the like. The high-temperature and high-pressure temperature and pressure relief valve is characterized in that a primary pressure relief throttle hole hood is arranged at an inlet of the valve body, a secondary adjusting pressure relief hole hood is disposed on the valve clack, multi-stage pressure relief hole hoods are further disposed in a channel of an outlet, a pressure relief water pipeline is arranged at the bottom of the valve body, and the nozzle on the pressure relief water pipe matches with the top end of the valve clack. The high-temperature high-pressure temperature and pressure relief valve has the advantages that 1, the relief valve can adapt to variation of steam load within a large range of 10%-100%, 2, a designed balance type valve spool reduces thrust of the actuator, 3, a linear-stroke execution mechanism is adopted to improve adjustment precision, 4, sealed surfaces of the valve spool and a valve grid are made from hard 'Stellite' alloy by means of surfacing and are scour-resistant, 5, the leakage rate is the minimum, 6, a low-noise design is adopted, 7, internal components can be conveniently assembled and disassembled without detaching the valve body in maintenance, and 8, the same actuator realizes simultaneous and instantaneous adjustment of water volume for temperature relief and steam pressure relief.
Description
Technical field:
The present invention relates to the High Temperature High Pressure steam converter valve, be specifically related to a kind of High Temperature High Pressure steam converter valve.
Background technique
Existing High Temperature High Pressure steam converter valve is made up of electric actuator, valve rod, valve body, support, valve gap, flap, nozzle etc., the valve body two ends are provided with inlet/outlet respectively, electric actuator drives the flow of flap control gaseous by valve rod, it mainly is that the import ratio goes out young, produce pressure reduction and reduce pressure, if pressure reduction is big, when it can't subtract, can only other decompressor be set again at outlet end, desuperheat is then sprayed water in valve by the valve bottom nozzle and is reached the desuperheat purpose.
Summary of the invention
In order to overcome above-mentioned defective, the purpose of this invention is to provide a kind of High Temperature High Pressure steam converter valve.
To achieve these goals, the present invention adopts following technological scheme:
A kind of High Temperature High Pressure steam converter valve, it comprises electric actuator, valve rod, valve body, support, valve gap, flap, nozzle etc., it is characterized in that: the import at valve body is provided with one-level decompression throttling escutcheon, secondary is set on flap regulates the decompression escutcheon, in the passage of outlet, the multi-step pressure reduction escutcheon is set again, in the bottom of valve body one defeated cooling water pipeline is set, the nozzle on the cooling water pipeline cooperates with the top of piston ring.
Between valve gap and support, heat radiation rack is set.
Between valve gap and valve body by filling block and seal ring selfsealings.
The utility model is can be fast with high pressure air reducing by multi-step pressure reduction in this valve body, and pass through valve bottom cooling water pipe water to nozzle, by nozzle cooling water is sprayed in the valve again, with the high-temperature gas desuperheat, according to different steam flows, the synchronization regulation spray water flux regulating pressure can better produce atomizing, by the heat radiation rack heat radiation, avoid influencing the work of electric actuator.
Advantage of the present utility model is: 1. outstanding Flow characteristics can adapt to the interior variation of 10-100% on a large scale of steam load; 2. the balanced type spool design reduces final controlling element thrust; 3. adopt straight journey actuator, improve degree of regulation; 4. spool and anti-the washing away of valve grid sealing surface weld deposit " Si Taili " cemented carbide; 5. minimum leak-down rate; 6. low noise design; 7. the reduction valve superstructure of You Huaing is not removed valve body and just can conveniently be carried out dismounting to internal component during maintenance; 8. spray water flux is regulated with steam and is reduced pressure by same final controlling element moment synchronization regulation.

Fig. 1 is the utility model structural representation.
Embodiment
Further specify below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of High Temperature High Pressure steam converter valve, it comprises electric actuator 1, support 2, valve rod 4, valve gap 7, flap 9, valve body 10, nozzle 11, it is characterized in that: the import 13 at valve body 10 is provided with one-level decompression throttling escutcheon 8, secondary is set on flap 9 regulates the decompression escutcheon, in the passage of outlet 14, multi-step pressure reduction throttling escutcheon 8 is set again; In the bottom of valve body one cooling water pipeline 12 is set, nozzle 11 cooperates with the top of flap 9; At valve gap 7 and 2 on support heat radiation rack 3 is set; 10 of valve gap 7 and valve bodies pass through filling block 5 and seal ring 6 selfsealings.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the technical solution of the utility model is not limited to the foregoing description, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
