Abstract
The utility model discloses an electric on-off type two-stage slow closure non-return butterfly valve. One side of the butterfly valve is connected with an electric device, and the other side of the butterfly valve is connected with a rotating oil cylinder; the electric device is connected with a clutch; and a rotating device is connected with a heavy punch. The valve is driven to open through the electric device and the clutch and is controlled to close through the rotating oil cylinder and the heavy punch, so that a valve opening device and a valve closing device are independent of each other, and the valve can be closed at two stages and can be prevented from being corroded by salt spray through the valve closing device; and the butterfly valve is low in overhaul and maintenance frequency and has long service life.
Description
Technical field
The utility model relates to butterfly valve.
Background technique
Carry tap water, desalination of sea water, the south water to north and draw the valve before Huang is gone into the compression pump of large-scale waterlines such as Shanxi is to damage in order to protect water pump not receive the impact of water hammer.Some adopt the safety check of medium back flow throttle downs, as revolve and answer formula safety check, multi-clove type safety check, DRV etc., owing to can not control automatically during throttle down; Impact to pipeline and valve is bigger, is prone to produce destroy, and some are by the safety check of hydraulic driving and control; Because adopt form structure, its oil cylinder and drive unit are received the erosion of mist outside the seashore, and open architecture is difficult for protection; Hydraulic butterfly valve influences working life, is difficult for realizing quick closing valve, slow throttle down when its electric butterfly valve cuts out, though can be realized quick closing valve, slow throttle down; But move the control system complex, easy fault, cost height.
Summary of the invention
The purpose of the utility model is to provide a kind of two stage of electronic clutch type Slow Close non-return butterfly valve, and it is the free Electric actuator Open valve of a kind of employing, weight throttle down, and two stages of can realize quick closing valve, closing are slowly closed the device of valve.
The technological scheme of the utility model realizes as follows:
The utility model comprises butterfly valve, Electric actuator, rotating hydraulic cylinder, and a side of butterfly valve is connected with Electric actuator, and opposite side is connected with rotating hydraulic cylinder, and the Electric actuator on the described butterfly valve is connected with clutch, and the rotating hydraulic cylinder on the butterfly valve is connected with weight.
The utility model be a little:
Because the utility model adopts Electric actuator Open valve, weight throttle down; Drive control valve unit and introduce clutch configuration, clutches engaged when driving valve, throw-out-of clutch when closing valve; Realize that the separate and rotating hydraulic cylinder of open and close control valve unit is an enclosed construction, effectively combine.Valve closer two stages of can realizing are closed valve.Simultaneously, Electric actuator, clutch and rotating hydraulic cylinder are enclosed construction, can prevent effectively that salt fog from corroding, and to environmental requirement is not high, repair and maintenance is few, long service life.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to accompanying drawing embodiment, the utility model is described further.
Among Fig. 1: the valve shaft 6 of butterfly valve 1 one sides connects an Electric actuator 2, clutch 3, and clutch 3 is connected with Electric actuator 2, is connected with a rotating hydraulic cylinder 4 and weight 5 on the valve shaft 6 on butterfly valve 1 opposite side, and weight 5 is connected with rotating hydraulic cylinder 4.
When needing Open valve, clutch 3 engagements, Electric actuator 2 drives butterfly valve 1 and opens; When closing butterfly valve 1, clutch 3 gets electric disengagement, and butterfly valve 1 receives the effect quick closedown of weight 5; The protection water pump, when being closed to several angle (70 degree), rotating hydraulic cylinder 4 one oil circuit mouths are blocked; Butterfly valve 1 only slowly cuts out with another oil circuit mouth oil return under the effect of weight 5, the protection pipeline.
