Description
Technical field
The utility model belongs to industry pipeline valve (butterfly valve, ball valve) the hydraulic pressure opening and closing devices such as oil, rock gas, generating, heat supply, tap water, chemical industry, boats and ships.
Background technique
The modes such as the valve opening and closing device employing of current China is manual, electronic, pneumatic, hydraulic pressure.Manually-operated gate opening and closing is not suitable with Automated condtrol, and large and medium-sized valve manual opening and closing labor intensity is large.Electric valve needs consideration explosion-proof in some occasion, also there is volume comparatively large simultaneously, is not suitable for using at some small space.Pneumatic valve opening and closing moment is limited, and Pneumatic actuator volume is comparatively large, large size valve application Pneumatic opening & closing less.Its manual operating device structure of existing hydraulic valve opening and closing device is comparatively large, and automaticity is not high.
Summary of the invention
The object of the invention is to the deficiency overcoming existing valve-gating technology, a kind of butterfly valve or ball valve hydraulic control valve opening and closing device are provided, to realize having larger opening and closing moment, again can manually-operable and the valve hydraulic pressure opening and closing device of small volume when can realize automatic control, the state of emergency (power-off, hydraulic fault).
Specifically, butterfly valve or ball valve hydraulic control valve opening and closing device, it is made up of oil cylinder with gear racks, tooth sector, worm gear, worm screw, splined shaft, eccentric handle, push buttonvalve, housing, position transducer; Oil cylinder with gear racks engages with tooth sector, and tooth sector is connected with the rotating shaft of institute's control valve and it has two position transducers detecting tooth sector rotational position; Splined shaft passes worm gear and realizes being combined with tooth sector or departing from by spring, and oil cylinder with gear racks is rotated by the tooth bar in it and two piston actuated tooth sector.
Worm gear and tooth sector are on an axis, and the involute spline holes of a same parameter is respectively arranged at the bottom of worm gear and the top of tooth sector, the in-built involute splined shaft of splined hole, and the upper end of splined shaft installs one for controlling the eccentric handle of splined shaft; The valve axis hole be connected with valve hinges is arranged at the bottom of tooth sector; Have a tooth bar and two pistons in oil cylinder with gear racks, pistons end has buffer, and the two ends of oil cylinder with gear racks have connecting tube to connect push buttonvalve, housing are fixed two position transducers and are positioned on tooth sector.
The utility model can realize the remote opening and closing of valve by hydraulic control, can be informed the opening/closing state of control deck valve door far away by position transducer, simultaneously also can the opening and closing of manually-operable valve.The present invention also can be used for other needs and rotates to an angle (≤360 °) mechanically.

Embodiment
As Figure 1-5,
Be made up of main parts size such as oil cylinder with gear racks, tooth sector, worm gear, worm screw, splined shaft, eccentric handle, push buttonvalve, housing, position transducers.Worm gear and tooth sector are on an axis, and the involute spline holes 18 of a same parameter is respectively arranged at the bottom of worm gear and the top of tooth sector, the in-built involute splined shaft 5 of splined hole 18, and the upper end of splined shaft installs one for controlling the eccentric handle 6 of splined shaft; The valve axis hole 17 be connected with valve hinges is arranged at the bottom of tooth sector 14; Have a tooth bar 11 and two pistons 10 in oil cylinder with gear racks, pistons end has buffer 9, and the two ends of oil cylinder with gear racks have connecting tube 13 to connect push buttonvalve 12, housing 1 are fixed two position transducers 15 and are positioned on tooth sector 14.
Working principle of the present invention is:
1. hydraulic control state (Fig. 1-2)
Pull eccentric handle to be in splined shaft is mentioned state (it is hollow that splined shaft is all positioned at worm gear), push buttonvalve is in closed condition (spring is by spool jack-up), oil inlet hole 7 oil-feed, oil inlet hole 8 is fuel-displaced, promotion piston moves right, and rotarily drives valve shaft turn clockwise with hour rack promotion tooth sector; Otherwise, oil inlet hole 8 oil-feed, oil inlet hole 7 is fuel-displaced, promotes piston and is moved to the left, and rotarily drives valve shaft be rotated counterclockwise with hour rack promotion tooth sector; In unlatching (closedown) position of valve, trigger position transducer signalling stop action by the contact on tooth sector, control platform far away also can obtain unlatching (closedown) information of valve simultaneously.
The buffer 9 at piston two ends can make the beginning section of piston movement and ending segment slow down, and band movable valve changes down official seal sealing hammering blow slowly.
2. Non-follow control state (Fig. 3-4) eccentric handle is in splined shaft down state that (a splined shaft part enters in tooth sector splined hole, tooth sector is connected) with worm gear, press the button valve and be in opening state, with handwheel (not shown in FIG.) shake worm screw rotarily drive worm gear, tooth sector rotarily drive valve shaft rotate, simultaneously piston-rack to the right (left side) mobile, now the oil in oil cylinder two chamber by connecting tube, push buttonvalve from (left side) chamber, the flow direction right side, left (right side) chamber.
3. after manually terminating, eccentric handle is turned back hydraulic control state, wait for hydraulic control next time.Worm drive can reduce steering force during manual opening and closing valve greatly.
What Fig. 5 provided is the utility model System Control Figure, and Pilot operated check valve 3-2 accesses rack cylinder 3-1, and Pilot operated check valve 3-2 is controlled by solenoid directional control valve 3-2.Pilot operated check valve plays a part to lock valve.
