Abstract
The utility model provides a novel stop valve which comprises a valve body, a valve clack, a valve sealing pad, a valve clack cover, a valve rod, a valve rod nut, sealing packing, an upper sealing seat, a sealing ring, a hand wheel, a valve cover and a sealing press sleeve. The valve body and the valve cover are connected through a connection stud, the valve body and the valve cover are sealed through the sealing ring, the upper sealing seat is arranged under the valve cover, the valve sealing pad is welded to the lower portion of the valve body and seals the valve body through a 45-degree conical face, the valve clack is made of chrome 13 steel, the valve clack is connected with the valve rod through half rings and is locked through the valve clack cover, and the valve clack cover is welded on the valve clack in a spot welding mode. The valve rod is connected with the hand wheel and is sealed by the sealing packing which is arranged through the sealing press sleeve, and the center of the hand wheel is of a square structure or a regular hexagonal structure or a round hole structure. The novel stop valve has the advantages of being reliable in sealing and convenient to operate and maintain, and is long in service life and suitable for various fields.
Description
Technical field
The utility model relates to technical field of valve manufacturing, is specifically a kind of novel cutoff valve.
Background technique
Stop valve belongs to one more common in valve field, and the open-shut device of stop valve is the flap of stopper, and sealing is plane or the extra large conical surface above, and square work flap is along the center line moving linearly of valve seat.The forms of motion of valve rod, also has lifting rotation rod-type to can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.Therefore, such stop valve valve that dams is suitable as cut-out or adjusting and throttling use very much.Because valve rod unlatching or the shutoff stroke of such valve are relatively short, and there is cutting function very reliably, due to the variation of valve seat port and the stroke of flap relation in direct ratio, be very suitable for the adjusting to flow again.But like product of the prior art is washed away and is destroyed in media flow process, therefore working life is short.
Model utility content
The purpose of this utility model is to provide a kind of novel cutoff valve at this, has the advantages such as sealing is reliable, convenient operating maintenance; Long service life, can be used for multiple fields.The utility model is achieved in that a kind of novel cutoff valve of structure, it is characterized in that: comprise valve body, flap, valve seal pad, valve clack cover, valve rod, Stem Mut, stuffing box packing, upper seal support, seal ring, handwheel, valve gap, sealed pressing sleeve;
Between described valve body, valve gap, connect by connecting stud; Between described valve body, valve gap, realize sealing by seal ring; Valve gap is divided into and is set up sealing seat;
Described valve seal pad is welded on valve body from bottom, adopts 45 degree conical surface seals; Flap adopts chromium 13 steel entirety to make, and flap adopted and splits annulus with being connected of valve rod, adopted valve clack cover locking, and valve clack cover point is welded on flap; Valve rod is connected with handwheel;
Described valve rod adopts stuffing box packing sealing, and stuffing box packing arranges by sealed pressing sleeve; Described handwheel middle part is positive tetragonal or positive hexagonal structure or borehole structure.
According to novel cutoff valve described in the utility model, it is characterized in that: stuffing box packing adopts flexible graphite packing.
The utility model has the advantage of: novel cutoff valve described in the utility model, comprises valve body, flap, valve seal pad, valve clack cover, valve rod, Stem Mut, stuffing box packing, upper seal support, seal ring, handwheel, valve gap, sealed pressing sleeve; Overall structure is simple; Have and seal reliable, convenient operating maintenance; Long service life, can be used for numerous areas.Handwheel adopts disposable steel plate punched moulding, has beautiful shape, and feel exquisiteness, facilitates the features such as durable.Stuffing box packing can adopt flexible graphite packing.
