Abstract
The utility model relates to a desuperheating water regulating valve, which is characterized in that a cylinder type valve seat 4 is arranged a valve body 1, a throttling ring 5 is arranged above the valve seat 4, and a flow equalizing cover 6 is arranged above the throttling ring 5. The lower part of the flow equalizing cover 6 is provided with a liquid flowing through hole, and the upper part is provided with a balancing hole. A cylinder body with a beveled valve core 7 is arranged in the flow equalizing cover 6. The upper end of the valve core 7 is connected with a valve rod 8. The utility model has the advantages of enhancing regulating precision, resisting cavitation erosion, lowering noise and effectively regulating and controlling temperature.
Description
Technical field: the utility model relates to a kind of valve field, a kind of specifically adjusting that is applicable to the boiler of power plant system temperature, and it can in time align temperature when boiler temperature exceeds CLV ceiling limit value, boiler is normally moved.
Background technique: existing cooling water modulating valve, because structure and material therefor is different, thereby the performance of product has very big difference, main existing problems are: easily cavitation erosion, defective such as leakage rate is big, and noise is big, and working life is short.
Summary of the invention: it is good that the purpose of this utility model provides a kind of adjusting function, and noise is low, anti-cavitation erosion, and long service life, and can control temperature timely and effectively, guarantee the cooling water modulating valve of the normal operation of boiler.
In order to realize above-mentioned purpose, the utility model adopts following technological scheme: a kind of cooling water modulating valve, comprise valve body that is provided with the liquid flow inlet and outlet and the valve gap that is installed on top, valve body is provided with fluid discharge and closing mechanism device, it is characterized in that described fluid discharge and closing mechanism device, comprise the drum type valve seat that is located in the liquid entrance, be located at the restrictor ring of valve seat top, the current-sharing cover bottom that is located at the restrictor ring top is provided with the hole of flow of liquid warp; Its top is provided with equalizing orifice; Be provided with the spool on cylindrical body band inclined-plane in the current-sharing cover, spool is provided with the valve rod that spool is moved up and down, and valve rod passes valve gap.
The utility model has adopted multistage pressure and temperature reducing structure, select quality material for use and be cured processing, effectively prevented to occur under Yin Gaowen, the High Pressure Difference operating mode cavitation erosion, and be designed to fabricated construction, dismantle very convenient, improved the design of flow area, driving moment is greatly fallen at the end, reduced the cost of driving mechanism, the structural feature of this valve is, the restrictor ring and the top current-sharing cover that adopt multi-disc disk with holes to be formed by stacking constitute throttling element, change the passage section of restrictor ring by the lifting of spool, thereby reach the purpose of regulating the cooling water flow.Because adopt restrictor ring to make the cooling water throttling be depressured to multistage step-down by one-level, thereby reduced pressure reduction, it is big fundamentally to have solved noise, the shortcoming of gasification erosion.Improved degree of regulation, anti-cavitation erosion, low noise, long service life, and can regulate and control temperature effectively.
Description of drawings:
Fig. 1 is the utility model structural drawing.
Embodiment:
Below in conjunction with Fig. 1 the utility model is elaborated.
As shown in Figure 1: form the valve gap 2 that comprises valve body 1 and be installed in valve body top of the present utility model, valve body is provided with imports and exports 3, is provided with discharging of liquid stream and closing mechanism device in the valve body; This mechanism comprises that the drum type valve seat 4 that is located at import and export, the restrictor ring 5 that is located at the valve seat top, restrictor ring top are provided with current-sharing cover 6, be provided with cylindrical body spool 7 in the current-sharing cover, spool 7 tops are provided with the valve rod 8 that spool 7 is moved up and down, and the import and export of valve body are straight-through type.
The utility model is installed in feed water pump to the pipeline of boiler, when boiler temperature is higher than CLV ceiling limit value, send signal by sensor, driving mechanism is received instruction and is started working, and valve is opened rapidly, liquid flows to into this valve, regulate step-down by this device, liquid stream is supplied with boiler, after receiving the signal that temperature normally is set, driving mechanism counter-rotating makes valve reduce flow or closes.The utility model inner body all selects for use high-quality stainless steel and alloy material to make, and 250～300 ℃ of adaptive temperatures bear pressure 25～32Mpa.
