Abstract
A pressure regulating valve ban solves the problems that coal gas leaks and use in complicated working conditions can not be met when the inner wall of a regulating butterfly valve is worn seriously, and is characterized by being formed by combining three regulating butterfly valves in a triangle manner in a ball body. An automatic regulating butterfly valve (1) is connected and provided with a DDZ type control instrument (2); an automatic regulating butterfly valve (3) is connected with a DKJ electric actuator (4); an automatic regulating butterfly valve (5) is connected with a DKJ electric actuator (6); and a normally open pipe (7) and the three regulating butterfly valves are connected in series on the ball body. The pressure regulating valve bank has the advantages of simple structure, convenient operation and long service life, and adapts to dust-containing gas flues in industries such as metallurgy, chemicals and the like so as to regulate flow rate and pressure.
Description
Technical field:
The utility model is specifically related to a kind of pressure regulator valve group, belongs to the technical field of valve machine-building, is applicable to do on the dust-laden gas pipe line of industries such as metallurgy, chemical industry to regulate the valve that flow and pressure use.
Background technique:
The pressure regulator valve group is a kind of valve of may command Industrial Stoves, particularly blast furnace top pressure, makes the key equipment of blast furnace ordinary production under pressure stable.Because using system medium dust loading is big, flow velocity is high, erosion is big, require matching used valve that good abrasion-resistance can be arranged, wear-resisting property is superior, the environmental pollution of avoiding gas medium to leak outside causing, energy waste, dangerous take place etc., but just known to the inventor, the used adjusting butterfly valve inner wall abrasion of present existing pressure regulator valve group is serious even mill is saturating, causes coal gas to leak outside, and can't satisfy the usage requirement of many complex working conditions.
Summary of the invention:
The purpose of this utility model is in order to remedy above deficiency, provide a kind of can be big in pipe-line system medium dust loading, normally use in flow velocity is high, erosion the is big environment, regulate the flow and the pressure of pipe-line system, thereby guarantee long-term normal use of system equipment, the pressure regulator valve group that prolongs life of equipment.
The utility model is to adopt following technological scheme to realize: described pressure regulator valve group, be combined in the spheroid by three adjusting butterfly valve triangles and form, it is characterized in that going up connection at automatic adjusting butterfly valve (1) is provided with a DDZ type electrodynamic element combination process control instrument (2), go up connection at automatic adjusting butterfly valve (3) a DKJ electric actuator (4) is set, go up connection at automatic adjusting butterfly valve (5) a DKJ electric actuator (6) is set, normal open pipe (7) is connected with three adjusting butterfly valves and is arranged on the spheroid.Generally, three adjusting butterfly valves, one one is normally closed in order often to open, the 3rd open and close operation is as regulating action.Because material adopts wear-resisting 360 steel, double-layer body tube, the design of large-angle inclined plate structure, and the local material thickening of valve rod will be passed through in the valve body, by using special welding consumables and welding procedure ginseng, make that this valve abrasion-resistance is good, wear-resisting property is superior, guaranteed valve safe and reliable in the spreadable life.
Pressure regulator valve group of the present utility model has simple in structure, is widely used, and is easy to operate, and long service life is easy to the advantage of repair and replacement.
Description of drawings:
Accompanying drawing is a pressure regulator valve group structural drawing
Among the figure: 1. regulate butterfly valve automatically, 2.DDZ type electrodynamic element combination process control instrument is 3. regulated butterfly valve automatically, and the 4.DKJ electric actuator is 5. regulated butterfly valve, 6.DKJ electric actuator, 7. normal open pipe automatically.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing embodiment, pressure regulator valve group as shown in drawings, combine by three adjusting butterfly valves, comprise automatic adjusting butterfly valve 1, DDZ type electrodynamic element combination process control instrument 2, automatically regulate butterfly valve 3, DKJ electric actuator 4, regulate butterfly valve 5, DKJ electric actuator 6 and normal open pipe 7 etc. automatically.Generally, regulate butterfly valve 1 automatically, regulate butterfly valve 3 and regulate 5, one of butterfly valves automatically is normally closed in order often to open automatically, the 3rd open and close operation is as regulating action; Three adjusting butterfly valves can be rotated function of use, to improve the whole service life of pressure regulator valve group.DDZ type electrodynamic element combination process control instrument 2 is the telecontrol instrument, can reach remote control function, enlarges using scope.The directionless when mounted requirement of this valve group can arbitrarily be installed with landform is on-the-spot; But the discharging of condensed water when guaranteeing that system high temperature descends, the normal open pipeline in this valve group generally places valve group below.Each pressure regulation butterfly valve in this valve group and normal open pipeline all are wear-resisting steel plate welding, have guaranteed safe handling and the life-span of valve group in the spreadable life, energy waste, environmental pollution and the security incident avoiding gas medium to leak outside causing.
