Abstract
The utility model relates to an exhaust steam valve, particularly relating to a high efficiency automatic exhaust steam valve. The high efficiency automatic exhaust steam valve mainly solves problems that in the prior art a condenser of a steam turbine forms a certain pressure due to different internal and external temperatures, when the pressure is too large, an accident happens, and exhaust efficiency is low. The high efficiency automatic exhaust steam valve comprises a supporting seat (1) which is provided with a valve body (2), and the high efficiency automatic exhaust steam valve is characterized in that: an upper part of the valve body (2) is provided with a valve handle (3), two ends of the valve body are respectively provided with an exhaust inlet (4), an exhaust outlet (5), and a bottom of the valve body is provided with two drainage outlets (6).
Description
Technical field
The utility model relates to a kind of exhaust steam valve, especially relates to a kind of high efficiency automatic exhaust valve.
Background technique
Generally in boiler, the chemical energy of fuel changes the rotor rotation of the heat energy and the driving steam turbine of steam into, transfers electric energy to through generator; At present, the water in the station boiler water cooling wall gets into drum after being heated into steam through coal dust firing, the steam in the drum continues heat absorption, becomes superheated vapor; Superheated vapor has very high pressure and temperature, gets into steam turbine, the rotor rotation of pushing turbine through pipeline; Form mechanical energy, when turbine rotor rotates, just drive the generator amature rotation, the lead cutting magnetic line in the generator unit stator produces induction current; Generator converts the mechanical energy of steam turbine into electric energy, and electric energy is delivered to the user after transformer boosts, and the steam that discharges heat energy is discharged from the steam-expelling port of steam turbine bottom; Be called weary gas; Weary gas is cooled in vapour condenser and condenses into water after the system cools, sends into low-pressure heater and gets back in the oxygen-eliminating device through condensate pump, accomplishes a circulation.Chinese patent discloses a kind of steam turbine installation, and (notice of authorization number: CN 100404799C), it comprises: steam generator; By steam-powered a plurality of low-pressure turbines from steam generator; Be used for to become from the vapor condensation of low-pressure turbine a plurality of stram condensers of condensed water: the water-supply line of condensed water being supplied with steam generator as feedwater; Water-supply line comprises a plurality of parallel connected feedwater heating pipelines, and feedwater heating number of lines is less than the quantity of stram condenser; With a plurality of low-pressure feed heaters; Wherein, each feedwater heating pipeline comprises at least one low-pressure feed heater, and this at least one low-pressure feed heater is arranged at least one of stram condenser, so that come heating condensate water through the steam of emitting from low-pressure turbine; At least one feedwater heating pipeline comprises a plurality of low-pressure feed heaters that are connected in series, and second quantity of the low-pressure feed heater that first quantity of the low-pressure feed heater interior with being arranged on first stram condenser is interior with being arranged on second stram condenser is different.But the condenser of this steam turbine can form certain pressure because internal and external temperature is different, when pressure produces when excessive, then can meet accident, and the efficient of steam discharge is lower.
The model utility content
The utility model provides a kind of high efficiency automatic exhaust valve; It mainly is to solve the condenser of existing in prior technology steam turbine because internal and external temperature is different, can form certain pressure, when pressure produces when excessive; Then can meet accident, and low etc. the technical problem of the efficient of steam discharge.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of high efficiency automatic exhaust valve of the utility model comprises bearing, and bearing is provided with valve body, and described valve body top is provided with valve handle, and two ends of valve body is respectively equipped with steam discharge inlet, steam discharge outlet, and the valve body bottom is provided with two drain ports.Big flange through the valve body two ends is connected to whole outlet valve on the steam turbine, when exhaust steam valve breaks down, utilizes the turn handwheel, can be so that the valve inner shadoof move up and down, thus valve rod also moves up and down, and therefore valve disc can carry out elevating movement.Steam when pressure reaches a certain amount of, can back down valving after the big flange entering of housing one end, after valving is opened, promptly can carry out steam discharge, and then the pressure of adjustment steam turbine and condenser.
As preferably, the middle part of described valve body is provided with water seal water inlet, water seal water outlet.
Therefore, the utility model has a plurality of turnover steam ports, intake-outlet on the valve body of outlet valve, and steam discharge efficient is higher, and is simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model.
Component, position and numbering among the figure: bearing 1, valve body 2, valve handle 3, steam discharge inlet 4, steam discharge outlet 5, drain port 6, water seal water inlet 7, water seal water outlet 8.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technological scheme of the utility model.
Embodiment: a kind of high efficiency automatic exhaust valve of this example, like Fig. 1, comprise bearing 1, bearing is provided with valve body 2, and valve body top is provided with valve handle 3, and two ends of valve body is respectively equipped with steam discharge inlet 4, steam discharge outlet 5, and the valve body bottom is provided with two drain ports 6.The middle part of valve body is provided with water seal water inlet 7, water seal water outlet 8.
During use; When the vapour pressure of valve body 2 one end steam discharges inlet 4 is excessive, can back down the valve disc of valve inner, valve disc can carry out elevating movement; Steam promptly is discharged from through the steam discharge outlet 5 of the other end; Thereby adjust the displacement of whole automatic exhaust valve, and then the pressure of adjustment steam turbine and condenser, overpressure protection formed.When breaking down, can rotating valve handle 3, under the drive of shadoof, valve rod, manually make valve disc carry out elevating movement.
The above is merely the specific embodiment of the utility model; But the structure characteristic of the utility model is not limited thereto; Any those skilled in the art is in the field of the utility model, and variation of being done or modification all are encompassed among the claim of the utility model.
