Abstract
The utility model discloses a guiding rod driving apparatus for a valve and belongs to the mechanical driving technical field. The hand wheel of the apparatus is fixed at the shaft end of a guiding tooth, and the shaft of the guiding tooth is engaged with a tooth wheel. The tooth wheel is fixed at the shaft end of a screw rod, and the screw rod and a nut turning block form a screw pair. The nut turning block is provided with a shaft hole matched with the shaft of the guiding tooth, and the shaft hole is provided with a fork head pin matched with a sliding block. The sliding block is positioned in a swinging arm, and a large guiding range high efficiency screw and a guiding rod cause the nut turning block to move in the left and right direction to drive the swinging arm to make the 0-90 DEG swing motion to open and close a valve door. Compared with an existing driving apparatus, the guiding rod driving apparatus for a valve can save 38% of labor, reduce 34% of space occupation and decrease 31% of height. The guiding rod driving apparatus for a valve meets the high efficiency self-locking requirement and is suitable for the valve with the larger through diameter.
Description
The utility model belongs to the mechanical transmission technical field, particularly a kind of valve guide rod transmission device that is mainly used in pipe valves such as butterfly valve and ball valve.
Now, pipe valves such as butterfly valve or ball valve except that the little latus rectum specification of part directly connects the valve rod with handle or handwheel, mostly connect valve rod by worm gearing and open and close with operated valve; The valve of big latus rectum need be finished with the two-stage worm gearing.So the employing worm drive is because so as to keeping valve opening and closing self-locking at an arbitrary position, reach than big speed ratio with reduction operation power, and the needs that adapt to conditions such as input shaft and the vertical easy-to-operat of valve rod.But cause transmission efficiency low thus, steering force strengthens relatively, and structure is not compact, weight is bigger.More novel valve planetary pinion transmission or harmonic driving mode, though compact structure, in light weight, velocity ratio is big and efficient is high, but be difficult to satisfy the self-locking of valve arbitrary position and input shaft and operational conditions such as valve rod is vertical, and processing technology is harsh, manufacture difficulty is big, so that is applied so far.
The purpose of this utility model is to break through the limitation of the above-mentioned valve tradition kind of drive, and both compact structure, high-effective and labour-saving, simple are provided, and can adapt to a kind of valve guide rod transmission device of self-locking and easy-to-operat again.
The purpose of this utility model is reached by following proposal: valve mainly is made up of handwheel, guiding tooth axle, gear, screw rod, nut block, slide block, swing arm, indicator panel, stop bolt, case lid and casing with the guide rod transmission device.Handwheel that can forward and reverse rotation is fixed on the guiding tooth axle head, guiding tooth axle and gear engagement, gear is fixed on the screw rod axle head, screw rod and nut block are formed screw pair, having axis hole on the nut block matches with guiding tooth axle, also have the jaw pin on it and slide block matches, slide block places in the swing arm, the switching position indicator panel of swing arm outer end dress valve, swing arm is in the left and right sides limit of 0 ° and 90 °, limited by two stop bolts that are installed on case lid and casing, the stop bolt can be made trace and adjust the location, and case lid and casing support whole transmission systems.
The utility model has following advantage and effect than the valve of prior art with worm gearing: (1). and efficient is higher, manual hand low 38%; (2). compact structure, institute takes up space few 34%; (3). in light weight 31%; (4). switching limit position stop bolt is stressed little by 20%; (5). make simple and easyly, working service is convenient.
Below in conjunction with accompanying drawing structure of the present utility model and principle are further described.
Fig. 1 is valve guide rod transmission structures figure
Fig. 2 connects figure for valve with the guide rod transmission device with valve
Among the figure, handwheel 1, guiding tooth axle 2, gear 3, screw rod 4, nut block 5, slide block 6, swing arm 7, indicator panel 8, stop bolt 9, case lid and casing 10, valve body 11, valve rod 12.
In accompanying drawing embodiment, handwheel 1 that can forward and reverse rotation is fixed on guiding tooth axle 2 ends, guiding tooth axle 2 and gear 3 engagements, gear 3 is fixed on screw rod 4 axle heads, screw rod 4 is formed screw pair with nut block 5, having axis hole on the nut block 5 matches with guiding tooth axle 2, also have the jaw pin on it and slide block 6 matches, slide block 6 places in the swing arm 7, swing arm 7 its inner axis holes and valve rod 12 axle heads match, the switching position indicator panel 8 of swing arm 7 outer ends dress valve, restriction swing arm 7 is installed on case lid and casing 10 at two stop bolts 9 of the left and right sides limit of 0 ° and 90 °, stop bolt 9 can be made trace and adjust the location, case lid and the whole transmission systems of casing 10 supportings, and its casing 10 bottoms and valve body 11 tops are by flange coupling.Valve is during with the work of guide rod transmission device, and handwheel 1 transmission guiding tooth axle 2 by can forward and reverse rotation and gear 3 are made the first order and slowed down, and gear 3 rotary screws 4 make nut block 5 move left and right that are enclosed within on the screw rod 4.The axis hole that matches with guiding tooth axle 2 on the nut block 5 slides when keeping mobile and leads; Jaw pin that also has on the nut block 5 and slide block 6 drive swing arm 7 and swing the open and close of operated valve in 0 ° to 90 ° scopes.The switching position (among the figure position of swing arm 7 valve is shown be in closed condition) that just on indicator panel 8, shows valve in 0 ° to 90 ° scope when swing arm 7 is swung.
When being used for less latus rectum of part and Low pressure valve, the small gear on gear 3 shown in Fig. 1 and the guiding tooth axle 2 can be cancelled, and handwheel 1 axle head direct and screw rod 4 is assembled, and this transmission device is simplified more.
This transmission system is had a style of one's own, and utilization spiral and guide rod make nut block 5 move left and right and drive swing arm 7 and 90 ° of swings of valve rod 12 dos, with the open and close of operated valve.Be implemented in big speed ratio and arbitrary position self-locking under the higher mechanical efficiency by the screw pair of big helical pitch and guide rod; Vertical with handwheel driving and maintenance input shaft with valve rod 12.
