Description
One, technical field: the utility model relates to a kind of valve control device, particularly relates to a kind of valve switch degree control gear.
Two, background technique: well-known, the current era that is applied in of valve is ubiquitous, act on very important, but the indication opening degree that common valve can not be clear and definite, thereby be difficult for understanding definitely flow and control timely and effectively, especially at the crucial moment strict to flow control, the opening degree of control valve will bring distinct result and influence timely and accurately.In addition, whether valve opening and closing, from the valve outer surface, can not find out (whether not knowing valve switch the particularly changing shifts process) intuitively, in the production scene because less than not open-and-shut Stroke Control indication intuitively, very easily cause open and close to put upside down, incur loss through delay switching time and cause the accident, and environmental pollution and casualties occur, cause heavy economic losses.
Three, model utility content:
The purpose of this utility model:, design a kind of valve switch degree control gear at the problem that background technique exists.
The technological scheme that the utility model adopted: a kind of valve switch degree control gear, contain upper press cover and valve gap, fixedly connected with fastening piece by sealing configuration between the valve body, valve stem casing is contained in upper press cover and the valve gap, be threaded by following screw mandrel or following screw between valve rod and valve flashboard or the flap, valve rod travel control cover is fixed on the upper press cover, on the left and right sides sidewall of Stroke Control cover, respectively be provided with long strip Stroke Control groove, the lifting nut sleeve of an indicating valve gate switch degree is contained on the threaded stem section in the Stroke Control cover, screw both sides symmetrical position is provided with two outstanding blocked ears, two blocked ears are sleeved in the two long strip Stroke Control grooves, and can be when valve rod rotates and valve flashboard or flap be in the lifting travel consistent motion, fixedly scale-board is installed on the Stroke Control cell wall.
Described valve switch degree control gear, diameter, the pitch of valve rod upper end screw thread and valve rod lower end screw thread all equate.
Described valve switch degree control gear, the diameter of valve rod upper end screw thread and valve rod lower end screw thread is proportional, or the pitch of valve rod upper end screw thread and valve rod lower end screw thread is proportional.
Described valve switch degree control gear, valve rod lower end screw thread are cylindricality screw rod or nut type cylindricality screwed pipe, and valve flashboard or flap have following screw or the following screw mandrel that is complementary with valve rod lower end screw thread.
Useful good effect of the present utility model:
1. valve rod travel control gear of the present utility model, simple in structure, cost is low, can control effectively to the valve opening degree timely and accurately, very easy to use, not only save time but also laborsaving, be easy to promotion and implementation, be particularly useful for the crucial place strict flow control.
2. valve rod travel control gear of the present utility model can externally be observed the valve opening degree exactly, brings convenience for operator's use, increase work efficiency, avoid causing unnecessary accident and property loss, reduced cost of production because of not clear on off state is put upside down open and close.
