Description
Technical field
The utility model relates to a kind of triangle flow control valve.Specifically it is a kind of modulating valve that can accurately control sewage treatment aeration flow, regulates continuously the air mass flow of all stage in aeration process, reaches energy-conservation object.Belong to mechanical structure technical field.
Background technique
In prior art, the aeration rate of sewage treatment aeration system is all generally by regulating the flow of every blower to control, due to the restriction of the flow adjustment range of blower fan own, can not meet the synchronization regulation requirement of the oxygen-supplying amount of biochemistry pool all stage, cause power waste.Along with reducing discharging the further raising of energy-conservation requirement, the domestic accurate aeration control system of having developed, this system is integrated into an intellectualizing system by the automatic detection of whole unit and biochemistry pool index content, according to biochemistry pool testing result, intelligent system can be adjusted the air demand of unit immediately, and the gas flow that enters each biochemistry pool is controlled by flow control valve.According to the requirement of accurate aeration system, this control valve should possess following technical requirements: (1) pressure loss is not more than 10mbar; (2) in 0～100% travel range of setting, there is stable continuous control characteristic.General control valve all can not meet above two requirements simultaneously in the market, and developing a kind of control valve that is exclusively used in accurate aeration will be the task of top priority.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby a kind of triangle flow control valve is provided, and this modulating valve pressure drop is little, and flow adjustment range is large, and air conditioning good linearity can meet the requirement of accurate aeration system to flow control valve.
The technological scheme providing according to the utility model, triangle flow control valve comprises valve body, valve plate, filler, gland, valve rod, support and fixing bolt; Filler, gland, support are installed in top at described valve body, and gland is fixedly connected with and compresses filler with valve body by gland bolt; Valve rod is arranged in support, and support is connected on valve body by fixing bolt; The top of valve plate is fixedly connected with by connecting bolt, nut with valve rod; Feature is: also comprise seal ring, described seal ring is installed on the valve seat on valve body, forms sealing pair with valve plate; What described valve channel normal section was semicircle and " V " font forms is fan-shaped, and " V " font two limits are straight line, and the angle on two limits is 60 °.
As further improvement of the utility model, described valve plate is planar, and valve plate is straight line below.
As further improvement of the utility model, " V " font two limit straight lines on the straight line that described valve plate is following and valve body form a triangle runner.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Because valve plate adopts planar, can effectively reduce the pressure loss; Owing to adopting triangle runner, the stroke of changes in flow rate and valve plate has good linear relationship, thereby air conditioning good linearity, can effectively increase regulation range stably; Pressure drop is little, and flow adjustment range is large, and air conditioning good linearity can meet the requirement of accurate aeration system to flow control valve.
Accompanying drawing explanation
Fig. 1 is the utility model structural front view.
Fig. 2 is the utility model structure left view.
Embodiment
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Figure 1 and Figure 2: the utility model comprises valve body 1, seal ring 2, valve plate 3, filler 4, gland 5, gland bolt 6, connecting bolt 7, nut 8, valve rod 9, support 10 and fixing bolt 11 etc.
The utility model is installed filler 4, gland 5, support 10 on the top of described valve body 1, and gland 5 is fixedly connected with and compresses filler 4 by gland bolt 6 with valve body 1; Valve rod 9 is arranged in support 10, and support 10 is connected on valve body 1 by fixing bolt 11; The top of valve plate 3 is fixedly connected with by connecting bolt 7, nut 8 with valve rod 9; Described seal ring 2 is installed on the valve seat on valve body 1, forms sealing pair with valve plate 3; What described valve body 1 passage normal section was semicircle and " V " font forms is fan-shaped, and " V " word two limits are straight line, and the angle on two limits is 60 °; Described valve plate 3 is flat, and valve plate is straight line below.
Working principle of the present utility model and process are as follows:
Drive unit of the present utility model is installed on the upper end 10-1 of support 10, and the top 9-1 of the drive nut in drive unit and valve rod 9 is connected to form kinematic pair.When drive unit receives control signal, drive nut rotates, and valve rod 9 is done elevating movement, and valve rod 9 drives valve plate 3 to do elevating movement.When the straight line A of valve plate 3 bottoms rises to the position over " V " font bottom surface B on valve body 1, valve is in opening state; When A rises to the C position shown in Fig. 2, valve is in full-gear.When opening state, " V " font straight line 1-1,1-2 on the straight line on valve plate 3 and valve body form a triangle runner, and during the straight line A in-position C of valve plate 3 bottoms, triangle Flow area is maximum, and now flow is maximum.From aerodynamics and control valve principle, not every opening process has fixing control characteristic stably, only has in valve is imported and exported the scope that has certain pressure reduction and just has adjusting function stably.Because the accurate aeration system requirements control valve pressure loss is no more than 10mbar, so can open initial point B to finding M, bis-points of N between standard-sized sheet terminal C by experiment, M point is the adjusting initial point when pressure loss 10mbar, N point is for having the adjusting terminal (now the pressure loss is approximately 3mbar) of steady control characteristic, and data corresponding to the performance curve between the M-N point the recording relation of flow (the stroke H with) are inputted in the database of accurate aeration system.In real work, the SC sigmal control by intelligent system completes the control of the utility model to gas flow, and meets the adjusting of the steady and continuous of the total travel that the M-N that sets orders.
Valve plate in the utility model adopts planar can effectively reduce the pressure loss; And adopt triangle runner can effectively increase regulation range stably, strengthen the linearly adjust of air.From experimental result, the utility model can meet the requirements of accurate aeration system to control valve completely.
