Description
Technical field
The utility model relates to inside screw non-rising stem type gate valve, is specifically related to the inside screw non-rising stem type gate valve with indicator.
Background technique
Inside screw non-rising stem type gate valve is referred to as again swingle gate valve, and valve rod and Stem Mut are in valve inner, directly contacts with fluid.Flashboard is the open-shut device of inside screw non-rising stem type gate valve, and during keying, valve rod only rotates to realize.The moving direction of flashboard and the moving direction of flowing medium are orthogonal, and inside screw non-rising stem type gate valve can not be used for regulating medium, and it can only be in standard-sized sheet or full off state.
Current inside screw non-rising stem type gate valve is on the market to judge whether it is in unlatching or closed condition from appearance, staff in operation, be easy to, because the carelessness in work causes error, therefore research and develop a kind of inside screw non-rising stem type gate valve with indicator feature and there is certain meaning.
Model utility content
The purpose of this utility model is in order to provide a kind of inside screw non-rising stem type gate valve with indicator.
For realizing the purpose of this utility model, the utility model adopts following technological scheme: comprise valve body, valve body is provided with valve seat, valve seat is provided with flashboard, Stem Mut and valve rod, valve rod connects handwheel by nut, and valve rod is provided with support, wherein: be provided with thrust-bearing above support, split annulus and gland, be provided with indicator above gland, described indicator is undertaken screwing connecting by pointer nut and the screw thread on valve rod.
As preferably, described indicator comprises direction board and can carry out the pointer that moves up and down on direction board, and described direction board one end is fixed on above gland.
As preferably, valve body is provided with valve gap, and described valve gap is fixedly connected with valve body with nut by stud, is provided with middle flange gasket between valve gap and valve body.
As preferably, be provided with graphite packing, filler pressing sleeve, Gland successively above valve gap, valve gap is fixed by stud bolt and nut and support.
From appearance, the beneficial effects of the utility model: be provided with indicator above gland, directly can judge that inside screw non-rising stem type gate valve is in unlatching or closed condition; Indicator comprises direction board and the pointer that can carry out moving up and down on direction board, according to the position of pointer at direction board, just can judge the size of the unlatching of inside screw non-rising stem type gate valve intuitively; Be provided with middle flange gasket between valve gap and valve body, strengthen sealing effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of direction board of the present utility model.
1 be valve body, 2 be valve seat, 3 be valve plate, 4 be Stem Mut, 5 be valve rod, 6 be middle flange gasket, 7 be valve gap, 8 be stud, 9 be nut, 10 be graphite packing, 11 be filler pressing sleeve, 12 be Gland, 13 be support, 14 be thrust-bearing, 15 be divided ring, 16 be gland, 17 be pointer nut, 18 be pointer, 19 for direction board, 20 is handwheel.
Embodiment
Further illustrate below in conjunction with accompanying drawing:
As shown in accompanying drawing 1-2: the utility model comprises valve body, valve body is provided with valve seat, valve seat is provided with flashboard, Stem Mut and valve rod, valve rod connects handwheel by nut, valve rod is provided with support, wherein: be provided with thrust-bearing above support, split annulus and gland, above gland, be provided with indicator, described indicator is undertaken screwing connecting by pointer nut and the screw thread on valve rod; Described indicator comprises direction board and the pointer that can carry out moving up and down on direction board, described direction board one end is fixed on above gland, valve body is provided with valve gap, described valve gap is fixedly connected with valve body with nut by stud, middle flange gasket is provided with between valve gap and valve body, be provided with graphite packing, filler pressing sleeve, Gland successively above valve gap, valve gap is fixed by stud and nut and support.
By the handwheel that turns clockwise, valve rod makes clockwise rotation, and pointer nut drives pointer to make slide downward, and Stem Mut drives flashboard to move downward, until ram seal face and sealing surface of seat match be closedown, blocks medium; When being rotated counterclockwise handwheel, valve rod only makes counter-clockwise rotary motion, and pointer nut drives pointer to make upward sliding, and Stem Mut drives flashboard to move upward, until flashboard is lifted off a seat, sealing surface upper end is unlatching, connects medium.
The purpose of this utility model, feature and advantage will in conjunction with the embodiments, are further described with reference to accompanying drawing.To contribute to understanding the utility model by embodiment, but not limit content of the present utility model.All distortion that those of ordinary skill in the art can directly derive from content disclosed in the utility model or associate, all should think protection domain of the present utility model.
