Abstract
The utility model discloses a quick-open flat gate valve, which comprises valve bodies, valve seats, a flashboard, a valve rod and a transmission mechanism. The valve body is assembled by a left half of the valve body and a right half of the valve body through a fixing element; the valve seats are respectively arranged in the left half of the valve body and the right half of the valve body; the flashboard is partially clamped between the two valve seats; and the end surface of the flashboard exposing outside the two valve seats is provided with the valve rod in a penetrating way; and the valve rod is driven to rotate by the transmission mechanism. The valve rod is driven to rotate by the transmission mechanism, and the flashboard is driven to swing left and right by the valve rod; moreover, the flashboard only needs to swing by certain small angle, and the valve can be opened completely, and the switching torque is smaller and the starting-stopping time is shorter; meanwhile, seal rings are arranged between the valve seats and the valve bodies; moreover, springs are also arranged on the butted end surfaces of the valve seats and the valve bodies; and the valve seats and the flashboard are always kept under excellent sealing states under the elastic effect of the springs, and the overall sealing property of the valve is improved.
Description
Technical field
The utility model relates to a kind of valve, especially a kind of quick open type plate valve.
Background technique
At present, existing plate valve mainly comprises valve body, valve seat, flashboard, valve rod, driving mechanism, valve seat is located in the valve body, flashboard is clipped between two valve seats, drive the unlatching and closure that moving up and down of flashboard realized valve by driving mechanism, so during with valve wide open or full cut-off, flashboard integral body all need be moved up and down, switch moment is bigger, opening and closing time is longer, simultaneously because valve seat and flashboard are in long-term friction, and corresponding flexible adjustment device is not set between valve seat and the valve body, so the seal ring between valve seat and the valve body is damaged easily, cause the overall tightness of valve relatively poor.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of sealing better, and switch moment is little, the quick open type plate valve that opening and closing time is short.
For achieving the above object, the utility model provides a kind of quick open type plate valve, comprise valve body, valve seat, flashboard, valve rod, driving mechanism, valve body is assembled by fixed block by left and right sides two halves valve body, be respectively equipped with valve seat in the two halves valve body, flashboard partly is folded between two valve seats, and flashboard is exposed on the end face outside two valve seats and is equipped with valve rod, and valve rod is driven by driving mechanism and rotates.
It is motor that the utility model can further be set to described driving mechanism, the output shaft of motor and valve rod interlock.
The beneficial effects of the utility model are: because valve rod is rotated by motor driving, one end of flashboard is set on the valve rod, so valve rod will drive flashboard when rotating with motor and swing, and flashboard only need be swung certain small angle, and can realize the standard-sized sheet of valve, switch moment is less, and opening and closing time is shorter.
The utility model also can further be set to described valve seat one end and flashboard offsets, and the other end and the valve body of valve seat offset, and the end face that compresses of valve seat and valve body is provided with spring, also is provided with seal ring between valve seat and the valve body.
Adopt said structure, between valve seat and valve body, spring is set, under the elastic reaction of spring, make valve seat and flashboard be in good sealing state all the time.
The utility model also can further be set to also be provided with on the valve body blowdown plug.
Adopt said structure, in case there is foul to block flashboard in the valve pocket, the blowdown plug of outwarding winding also can carry out blowdown, and is simple in structure, and easy accessibility is convenient to repair.
Description of drawings
Fig. 1 is a structure sectional view of the present utility model;
Fig. 2 is a structure front view of the present utility model.
Embodiment
Provided a kind of quick open type plate valve as shown in Figure 1, 2, comprise valve body 1, valve seat 2, flashboard 3, valve rod 4, driving mechanism 5, valve body 1 is formed by fixedly connecting by screw 6 assemblings by left and right sides two halves valve body 1, be respectively equipped with valve seat 2 in the two halves valve body 1, flashboard 3 parts are folded between two valve seats 2, flashboard 3 is exposed on the end face outside two valve seats 2 and is equipped with valve rod 4, and valve rod 4 is driven by driving mechanism 5 and rotates.Described driving mechanism 5 can be hand wheel, worm gear, Pneumatic actuator or Electric actuator, preferred motor.Described valve seat 2 one ends and flashboard 3 offset, and the other end of valve seat 2 and valve body 1 offset, and the end face that compresses of valve seat 2 and valve body 1 is provided with spring 7, also are provided with seal ring 8 between valve seat 2 and the valve body 1, also are provided with blowdown plug 9 on the valve body 1.
Valve rod 4 is driven by driving mechanism 5 and rotates, and valve rod 4 drives flashboard 3 and swings, and simple in structure, valve opening and shut-in time are shorter, and working efficiency is higher.
Claims (5)
1. quick open type plate valve, it is characterized in that: comprise valve body, valve seat, flashboard, valve rod, driving mechanism, valve body is assembled by fixed block by left and right sides two halves valve body, be respectively equipped with valve seat in the two halves valve body, flashboard partly is folded between two valve seats, flashboard is exposed on the end face outside two valve seats and is equipped with valve rod, and valve rod is driven by driving mechanism and rotates.
2. quick open type plate valve according to claim 1 is characterized in that: described driving mechanism is a motor, the output shaft of motor and valve rod interlock.
