Description
Technical field
The utility model relates to valve field, is specifically related to electric flow control valve.
Background technique
Traditional electric flow control valve, when valve closing, spool place stress surface is cambered surface, medium by time pressure that spool is caused large, be difficult to open.While valve rod and spool are that such installation procedure of split type installation is various.Spool is all to adopt side dress, causes like this in normal using process and needs need to first disassemble pipeline when changing or safeguarding spool, causes replacing to safeguard inconvenient; Also having at intake-outlet is to be all designed to circle, and such design is not easy to calculate control flow.
Model utility content
Technical problem to be solved in the utility model is to solve conventional electric flow control valve, when valve closing, spool place stress surface is a cambered surface, medium by time cause spool be subject to resistance large, be difficult to open, while valve rod and spool are that such installation procedure of split type installation is various, also having spool is all to adopt side dress, causes so in use and need to first disassemble pipeline in the time that needs are changed or safeguarded spool, causes replacing to safeguard inconvenient; Also having at intake-outlet is to be all designed to circle, and such design is not easy to calculate problems such as controlling flow.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is to provide a kind of electric flow control valve, comprise the straight tube-like housing of vertical setting and upper end open, its sidewall is provided with the water intake and the water outlet that are oppositely arranged, also comprises valve rod and spool, valve seat.Valve rod vertically passes the bottom opening place of housing and stretches out the top of housing and have valve seat to be packaged in valve inner, spool comprises from top to bottom horizontally disposed top board and base plate successively, described top board is fixed on the lower end of described valve rod, described top board and base plate are fixed together by connecting plate, the cross section of described connecting plate is V-arrangement, the bottom opening place of described housing mounts cover and is fixed with valve seat, described water intake is rectangular, by rotating described valve rod, drive described connecting plate to move to it and cover described water outlet, realize the valve that closes of described electric flow control valve; By rotating described valve rod, drive described connecting plate to move to it and separate with described water outlet, realize the valve of opening of described electric flow control valve.
In such scheme, the central axis along described valve rod on the bottom surface of described base plate is provided with running shaft, and described running shaft rotates and is arranged on described enclosure interior valve seat in suitable with it swivelling chute along its central axis.
In such scheme, between the end face of described top board and described housing, be provided with spherical member, described spherical member rolls and is arranged in the groove on the end face of described top board.
In such scheme, the joint of described valve rod and described housing is provided with seal ring.
In such scheme, described top board and base plate are sector.
The utility model, because spool is connected to form by the connecting plate of indent by top board and base plate, making its stress surface is V-arrangement face, can the pressure of dispersion medium to spool, thereby more easily open or throttle down, and valve rod and spool are fixed together, make it simple in structure, easy for installation, greatly reduce difficulty of construction, meanwhile, because housing has taked lower ending opening to mount cover the structure of valve seat, in the time changing or dismantle, valve seat being opened can be without dismounting pipeline.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, a kind of electric flow control valve that the utility model provides, comprises the straight tube-like housing 1 of vertical setting and upper end open, and the bottom opening place of housing 1 mounts cover and is fixed with valve seat 2, its sidewall is provided with the water intake 3 and the water outlet 4 that are oppositely arranged, also comprises valve rod 5 and spool 6.
Valve rod 5 vertically passes in the bottom opening place of housing 1 and stretches out the top of housing 1 and have valve seat to be packaged in enclosure interior, and valve rod 5 is provided with seal ring with the joint, upper end of housing 1.
As shown in Figure 2, spool 6 comprises from top to bottom horizontally disposed top board and base plate successively, and top board is fixed on the lower end of valve rod 5, and top board and base plate are fixed together by vertical setting and the connecting plate that concaves.On the bottom surface of base plate, be provided with running shaft 7 along the central axis of valve rod 5,7, running shaft rotates and is arranged on housing 1 inner valve seat 2 in suitable with it swivelling chute along its central axis, like this in the time of switch valve, by the location of running shaft 7, spool 6 just can not depart from, and uses also more safe.Between the end face of top board and housing 1, be provided with spherical member 8, spherical member 8 rolls and is arranged in the groove on the end face of top board, in the time of switch valve, between the inside top surface of spool 6 and housing 1, just can reduce friction by the rolling of spherical member 8, thereby reduce wearing and tearing, increased working life.Top board and base plate are sector.
As shown in Figure 3, Figure 4, by rotary valve rod 5, drive connecting plate to move to it and cover water outlet 3, realize the valve that closes of electric flow control valve; By rotary valve rod 5, drive connecting plate to move to it and separate with water outlet 3, realize the valve of opening of electric flow control valve.
