Abstract
The utility model discloses a drainage regulating valve which is suitable for a high pressure heater of the boiler system of a power plant. The utility model not only can discharge high temperature condensing water in time, but also can effectively prevent that steam enters the condensing water and enters a water discharging adjusting valve of a water discharging pipeline. The inner part of a valve body is provided with a condensing water discharging and closing mechanism which comprises a cylinder type valve seat in a water outlet, a flow equalization cover arranged above a valve seat, a diverging opening arranged at the lower part of the flow equalization cover, a bell jar-shaped balance type valve core arranged in the flow equalization cover, a groove arranged at the outer edge of the upper opening of the valve core, a seal ring arranged in the groove, and a vale rod arranged in the valve core, wherein, the outer edge of the lower opening of the valve core forms an oblique plane, and the valve rod passes through a valve cover.
Description
The utility model relates to a kind of valve mechanism, specifically a kind of being applicable in the boiler of power plant system high pressure heater, and it can get rid of high temperature knot water wherein in time, can stop steam to sneak into the drain regulating valve that water of condensation enters drain water piping again effectively.
Domestic production at present be applied in steam trap connection in the high-pressure heater, its structure and characteristics are respectively arranged because structure and material therefor is different, thereby the performance of product is also variant.The main problem that exists is: leak, adjusting function is poor, can not realize carbonated drink separation effectively, the life-span is short, work is unreliable.
The purpose of this utility model is to provide a kind of adjusting and good seal performance, life-span to grow and can realizes the drain regulating valve that carbonated drink is separated effectively.
To achieve these goals, the utility model adopts following technological scheme: a kind of drain regulating valve, comprise valve body that is provided with the condensed water import and export and the valve gap that is loaded on valve body top, be provided with condensed water discharging and closing mechanism device in the valve body, it is characterized in that: described condensed water discharging and closing mechanism device comprise the cartridge type valve seat that is located in the condensed water water outlet, be located at the telescopic current-sharing cover of cartridge type valve seat top, current-sharing cover bottom is provided with the condensed moisture discharge orifice that water intake is communicated with water outlet, be provided with bell jar type balanced type spool in the current-sharing cover, spool end opening outer rim becomes the inclined-plane, its outer rim suitable for reading is provided with groove, be provided with the seal ring that cooperates with current-sharing cover inwall in the groove, spool is provided with the valve rod that makes spool do axial motion, valve rod passes valve gap.
Compared with the prior art the utility model has conspicuous advantage, because the utility model has adopted the pressure balance type structure, thereby good airproof performance, operational torque is little, highly sensitive, remain the condensation water level of certain altitude owing in the pipeline again, so can realize carbonated drink separation effectively.
Below in conjunction with accompanying drawing the utility model is elaborated.
Accompanying drawing is the utility model structural representation.
As shown in the figure, form the valve gap 12 that comprises valve body 13 and be installed in valve body top of the present utility model.Valve body is provided with water intake 14 and water outlet 1, is provided with condensed water discharging and closing mechanism device in the valve body.This mechanism comprises the cartridge type valve seat 2 that is located in the condensed water water outlet, be located at the telescopic current-sharing cover 3 of cartridge type valve seat top, current-sharing cover bottom is provided with the condensed moisture discharge orifice 4 that water intake is communicated with water outlet, be provided with bell jar type balanced type spool 5 in the current-sharing cover, spool end opening outer rim becomes inclined-plane 6, and its outer rim suitable for reading is provided with groove 7, is provided with the seal ring 8 that cooperates with current-sharing cover inwall in the groove, spool 9 is provided with the valve rod 10 that makes spool do axial motion, and valve rod passes valve gap 12.The intake-outlet of valve body connects for the angie type flange.The utility model is installed in the below of high-pressure heater, causes certain height water-head, and when high-pressure heater was just started working, because the connecting tube middle water level is very low, the utility model was in closed condition.At this moment the valve base sealing inclined-plane is close on the sealing inclined-plane of spool, resistant to elevated temperatures seal ring sealing is arranged between spool top and the current-sharing cover, thereby condensed water in high temperature can not enter this practical inside, more can not enter drain water piping, after high-pressure heater work a period of time, water of condensation is cumulative, water level is more and more higher, when water level meets and exceeds a certain setting value, controlling driving mechanism of the present utility model starts working, drive spool by valve rod and move upward, at this moment the throttle orifice on the current-sharing cover is opened gradually, and water of condensation begins to enter the utility model inside, and enter drain water piping by this device and arrive oxygen-eliminating device, the flow that passes through is along with the height that spool rises increases, and when spool rising 30mm, flow reaches maximum value, when spool rises to a certain height, at this moment the driving mechanism valve rod that begins to reverse drives spool and moves downward, and hydrophobic flow reduces, and water level is risen.The utility model inner body is all made with stainless steel or alloy steel material except that seal ring, pressure adaptation 1-6.4mPa, and Maximum operating temperature can reach 450 °.
