Abstract
The utility model provides a regulating valve with a multifunctional connecting block, and belongs to the technical field of pneumatic regulating valves. The regulating valve comprises an actuator, a valve body valve element mechanism, a push rod for connecting the actuator and the valve body valve element mechanism and a connecting shaft. The upper end of the push rod is connected with the actuator, the lower end of the push rod is connected with the connecting shaft through an arranged connecting block, and the lower end of the connecting shaft is connected with the valve body valve element mechanism. The regulating valve with the multifunctional connecting block is simple in structure and reasonable in design, the push rod and the connecting shaft are connected through the connecting block which is formed through stamping in one time and has a travel indication function, the situation that the travel accuracy of the valve is affected due to gaps generated by threaded connection is avoided, disassembly and assembly are convenient, accessory installation space is increased to assist accessory installation, travel indication is made to be more convenient and more distinct, and a pneumatic regulating valve is made to be light in overall structure and attractive and elegant in appearance.
Description
Technical field
The utility model belongs to pneumatic control valve technical field, is specifically related to a kind of modulating valve with multi-functional contiguous block.
Background technique
In recent years, the product structure type of domestic valve industry develop rapidly ，Ge valve producer emerges in an endless stream.But the push rod of domestic existing actuating mechanism for pneumatic control valve adopts thread type to connect with valve rod, this screw connection structure easily produces gap and lax in running, affects valve regulated precision; Taking up room of screw thread fixture block is larger, for annex, installs and stroke indication installation inconvenience, thereby affect on-the-spot stroke indication, observes.
Model utility content
The problem existing for prior art, the purpose of this utility model is that design provides a kind of technological scheme of the modulating valve with multi-functional contiguous block.
Described a kind of modulating valve with multi-functional contiguous block, the push rod and the coupling shaft that comprise actuator, valve body spool mechanism and connection actuator and valve body spool mechanism, it is characterized in that described push rod upper end is connected with actuator, lower end is connected with coupling shaft by the contiguous block arranging, and described coupling shaft lower end connects valve body spool mechanism.
Described a kind of modulating valve with multi-functional contiguous block, is characterized in that described contiguous block comprises that the left and right of integrated punching moulding connects fixture block, and described left and right connects fixture block and by fixing bolt, push rod and coupling shaft clamped.
Described a kind of modulating valve with multi-functional contiguous block, is characterized in that described both sides, contiguous block front and back connect the auxiliary contiguous block for installation accessories by the connecting bolt arranging.
Described a kind of modulating valve with multi-functional contiguous block, is characterized in that described both sides, contiguous block front and back are provided with stroke pointer.
Above-mentioned a kind of modulating valve with multi-functional contiguous block, simple in structure, reasonable in design, adopt the one time punching molded contiguous block with stroke indication to connect push rod and coupling shaft, it has been avoided existing thread type to connect the gap producing and has affected the stroke accuracy of valve, is convenient to dismounting, increase annex installing space, auxiliary installation accessories, makes stroke indication convenient, clear, makes that pneumatic control valve overall structure is light and handy, beautiful shape is generous.

Embodiment
Below in conjunction with Figure of description, further illustrate the utility model.
As shown in the figure, a kind of modulating valve with multi-functional contiguous block comprises push rod 9 and the coupling shaft 6 of actuator, valve body spool mechanism and connection actuator and valve body spool mechanism.Push rod 9 upper ends are connected with actuator, pallet 10 and diaphragm 12 that specifically push rod 9 upper ends connect in actuator by nut 13.Push rod 9 lower ends are connected with coupling shaft 6 by the contiguous block 7 arranging.Contiguous block 7 specifically comprises that the left and right of integrated punching moulding connects fixture block, and left and right connects fixture block and by fixing bolt 14, push rod 9 and coupling shaft 6 clamped.The auxiliary contiguous block 7a that contiguous block 7 both sides, front and back connect for installation accessories by the connecting bolt 15 arranging, and contiguous block 7 both sides, front and back are provided with stroke pointer 7b, and stroke pointer 7b is corresponding with the scale-board 8 in valve.Coupling shaft 6 lower ends connect valve body spool mechanism.Valve body spool mechanism comprises valve gap 4, valve core valve stem 3, valve seat 2, valve body 1 and filler 5, and wherein valve core valve stem 3 is connected with coupling shaft 6 lower ends.
When external air source enters lower film chamber B1, act on Compress Spring 11 on diaphragm 12 and do upper and lower piston movement, thereby drive push rod 9, contiguous block 7 and coupling shaft 6 motions, the stroke pointer 7b indicating graduation board 8 of contiguous block 7.
Shown in the above and figure is only preferred implementation of the present utility model.It should be pointed out that for the person of ordinary skill of the art, not departing under the prerequisite of the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
