The accompanying drawing explanation
Fig. 1 is phantom of the present utility model.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage are more clear, in conjunction with the following drawings, and to its further description.
As Fig. 1, movable flashboard 2 formula gate valves, comprise handwheel 20, support 15, bonnet 7 and valve seat 1, handwheel 20 is arranged at support 15, support 15 is connected with nut 14 by swing bolt 13 with bonnet 7 one ends, the other end is connected with nut 12 by stud bolt 11, bonnet 7 is connected by stud bolt 4 and nut 5 lockings with valve seat 1, also comprise valve rod 3 and flashboard 2, valve rod 3 runs through handwheel 20, support 15, bonnet 7 and valve seat 1, valve seat 1 is provided with valve pocket, and flashboard 2 is placed in valve pocket, and is connected with the bottom of valve rod 3.
When flashboard 2, under valve rod 3 drives, while dropping to sealing station, valve rod 3 continues to insert flashboard 2 in downwards, and strut flashboard 2 under the decline active force, the sealing surface of flashboard 2 and valve seat 1 is reached and combine closely, and reaches sealing state.
The utility model can make valve not produce friction before sealing, has avoided traditional gate valve when impelling valve to reach sealing, the major injury of the sealing surface that the strong friction of generation causes; Make it arrive better sealing effect, improve its working life simultaneously.
Also comprise filler packing 8, the top of bonnet 7 is provided with lumen pore, in lumen pore, with valve rod 3, leaves space, is filled with stuffing box packing packing 8 in space.
Also comprise gland 10, gland 10 is through valve rod 3 wedging bonnets 7, and compression filler packing 8.
Gland 10 is connected with bonnet 7 by swing bolt 13 and nut 14.
The bottom of swing bolt 13 is provided with hole, inserts in the groove mated with bonnet 7, and latch 9, through hole and groove, makes gland 10 compress filler packings 8, makes valve rod 3 and bonnet 7 reach sealing state.
Also comprise the beam hanger 18 of being close to valve rod 3, beam hanger 18 runs through handwheel 20 and support 15.
Flashboard 2 offers penetrating groove, and the bottom of valve rod 3 is provided with the wedge head of inverted-triangular, and the front end of wedge head inserts in penetrating groove.
Be provided with sealing gasket 6 between bonnet 7 and valve seat 1.By press seal pad 6, bonnet 7 and valve seat 1 are combined closely, reach sealing state.
Valve rod 3 is provided with the hexagon nut 21 be placed on handwheel 20, locking handwheel 20.By locking hexagon nut 21, reach the effect that prevents that handwheel 20 from coming off.
The movable gate plate-type gate valve is by clockwise or be rotated counterclockwise handwheel 20, the Stem Mut 17 that rotarily drives by handwheel 20 is done the equidirectional motion, and do the equidirectional motion by the valve rod 3 that rotarily drives of Stem Mut 17, and drive flashboard 2 and do the direction switch motion, thereby make valve enter working state.When handwheel 20 turns clockwise, drive Stem Mut 17 and valve rod 3 and move downward with flashboard 2 by valve rod 3, will be slack when the bottom of flashboard 2 arrives design attitude, and valve rod 3 is under the turning effort power of handwheel 20, continue to move downward, the inverted triangle wedge head of bottom inserts in the groove of flashboard 2, and struts flashboard 2, finally make two of the left and right sealing surface of flashboard 2 and two sealing surface close contacts of valve seat 1, reach sealing state.Now, valve is in closed condition.When being rotated counterclockwise handwheel 20, the Stem Mut 17 that rotarily drives by handwheel 20 is done the equidirectional motion, and do the equidirectional motion by the valve rod 3 that rotarily drives of Stem Mut 17, and drive flashboard 2 is done ascending motion, when valve rod 3 rises, the wedge head of bottom first leaves flashboard 2, under the double reaction plus of the retraction elastic force that the pressure of the pipeline of flashboard 2 and flashboard 2 are own, flashboard 2 inwardly bounces back, the sealing surface of sealing surface and valve seat 1 breaks away from, and move upward under the drive of valve rod 3, now, valve is in opening state.As can be seen here, no matter valve is the action opened or closed, and flashboard 2 is all very short with the time of contact when reaching sealing state of 1 liang of sealing surface of valve seat, has avoided the strong friction between sealing surface and sealing surface.Simultaneously, the effect that struts by the wedge head to flashboard 2, solved valve in use because the compensation problem after sealing surface wear.Effectively extend the working life of valve, also facilitated the secondary maintenance of valve.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned mode of execution.Therefore, the utility model is not limited to embodiment disclosed and described above, to modifications and changes more of the present utility model, also should fall in the protection domain of claim of the present utility model.In addition, although used some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the utility model.
