Abstract
The utility model relates to a gate plate valve in a rolling type. The upper portion and the lower portion of a gate plate are provided with a pair of rolling wheels respectively on a valve wall and a slope rolling track to roll. When the gate plate rolls into the rolling track, the inner pressure of the pipeline drives the gate plate to close an outputting opening provided with a soft seal component. Meanwhile, the upper rolling wheel and the lower rolling wheel do not contact with the rolling track. When the valve is opened, a manual device or a mechanical device upward lift the gate plate by a leading screw. The rolling wheels upward roll along the slope rolling track and a plane rolling track. The gate plate leaves the outputting opening without friction. The gate plate valve in the rolling type has low lifting force and no leakage on the soft sealing component and the manufacture precision is reduced. The utility model can widely replace the prior gate valve to be used for the liquid control of large through diameter with high pressure.
Description
The utility model relates to the invention of pipeline valve.
At present known gate valve is made of valve plate and valve port, and flashboard and valve port are by the precision fitted seal, and the lifting of flashboard and valve port produce sliding friction, and lifting force is big, how to reduce that precision can improve sealability again and the reduction lifting force is the gate valve urgent problem.
The purpose of this utility model is: it is low to design a kind of precision, and depended on pressure is implemented sealing, and the rolling gate valve of roller is equipped with in the flashboard both sides.
The purpose of this utility model is achieved in that gate valve delivery outlet circular groove is embedded in annular soft seal ring.Cast out inclined-plane raceway and plane raceway on the shell body wall of delivery outlet both sides, the roller in flashboard two side channels is fixed with Xiao's axle, constitutes the rolling gate valve.Have slotted hole in the middle of the flashboard, be connected with leading screw with Xiao Ding, flashboard with Xiao Ding be fulcrum can about freely swing.Handwheel sleeve with the key power transmission, rotates the handwheel swivel nut and rotates in the middle of the swivel nut external diameter, and screw mandrel drives flashboard by Xiao Ding and rolls along inclined-plane raceway and plane raceway up or down.Do not contact with soft seal ring when flashboard rolls, just after roller rolled into the inclined-plane raceway, flashboard was pushed down soft seal ring delivery outlet is closed under the pipeline pressure effect.
Have excellent sealing performance but also change the flashboard sliding friction into rolling friction owing to adopt such scheme not only to reduce precision, reduced steering force.
Accompanying drawing is the structural representation of rolling gate valve, has described embodiment of the present utility model, and diagram is the valve closed position.
Among the figure, key (1), nut sleeve (2), handwheel (3), gland (4), valve body (5), leading screw (6), soft seal ring (7), plane raceway (8), Xiao Ding (9), slotted hole (10), flashboard (11), roller (12), soft seal ring (13), delivery outlet (14), plane raceway (15), inclined-plane raceway (16), roller (17).
When driving valve: rotate handwheel (3), drive nut sleeve (2) rotation by key (1), nut sleeve (2) is glanded that (4) are spacing can not to move up and down, thereby leading screw (6) moves upward, by Xiao Ding (9) pulling flashboard (11) upwards, flashboard (11) drives roller (12) (17) and scrolls up along the raceway (8) (15) on the valve body (5) respectively, at this moment flashboard (11) leaves the soft seal ring (13) on the delivery outlet (14), when leading screw (6) with flashboard (11) when being promoted to fully open position, valve is in full-gear.
When closing valve: backward rotation handwheel (3), leading screw (6) is downward, and it is downward to promote valve plate (11), and flashboard (11) makes the roller (12) (17) on the flashboard (11) roll along corresponding raceway (8) (15) downwards under fluid pressure action.Flashboard (11) moves to delivery outlet (14) along slotted hole (10) after roller (17) drops to inclined-plane raceway (16) from plane raceway (15), pushes down seal ring (13) valve cuts out.Rubber seal (7) is adopted in the sealing of leading screw (6) and valve body (5).
The working principle of Here it is rolling gate valve.Flashboard rolls, and not only maneuvering capability is little, and flashboard and Sealing do not produce friction.The pass depended on pressure of having no progeny makes valve plate be close to soft seal ring, does not have to leak, and it can be widely used in the big latus rectum of high pressure, replaces existing gate valve.
Claims (2)
1, a kind of rolling gate valve that is used for fluid control, depended on pressure is implemented sealing, roller is equipped with in the flashboard both sides, it is characterized in that: gate valve delivery outlet (14) circular groove is embedded in soft seal ring (13), cast out inclined-plane raceway (16) and plane raceway (8) (15) on the shell body wall of delivery outlet (14) both sides, the roller (12) (17) in flashboard (11) two side channels is fixed with Xiao's axle.
2, according to the described rolling gate valve of claim 1, it is characterized in that: have slotted hole (10) in the middle of the flashboard (11), be connected with leading screw (6) with Xiao Ding (9), flashboard (11) with Xiao Ding (9) be fulcrum can about freely swing.
