Abstract

A throttling stop valve comprises a valve body, a valve cap, a valve rod, a valve core, soft corrugated pipes, a valve seat and a handle, wherein the handle is arranged at the top of the valve rod; the valve rod penetrates through the valve cap connected with the valve body; convex shoulders are arranged on the valve rod; an inner hole screw nut at the lower end of the valve rod is matched with external threads of a valve core connecting rod; the valve core connecting rod is fixed on a valve cap bracket through a locating rack with a copper sleeve; the lower end of the valve core connecting rod is connected with a round-platform-shaped throttling stop valve clack; the lower end of the throttling stop valve clack is connected with a rhombus-shaped barrel throttle valve clack; the soft corrugated pipes are arranged in the inner chamber of the valve body; and the upper ends of the corrugated pipes are arranged between the valve cap and the valve body, and the lower ends are connected with the round-platform-shaped throttling stop valve clack. The throttling stop valve can avoid the phenomenon of rust or failing of screwing because the valve rod is not in contact with fluids, has low probability of damage because the valve clacks and the valve seat sealing surface can not be directly eroded by the fluid, has not only a double cut-off function, but also a throttling effect, and has the characteristics of good sealing effect and long service life.

Description

Throttling stop valve
Technical field
The present invention relates to a kind of throttling stop valve.
Background technique
Existing throttling stop valve, the one, get rusty because of lubrication problem in valve rod and valve gap connecting part, or because of filler degeneration effect of attrition its mechanical life; The 2nd, flap and sealing surface of seat are directly washed away by fluid, easily cause damage, cause leaking.
Summary of the invention
The present invention overcomes the deficiency in the above-mentioned throttling stop valve design, and a kind of throttling stop valve is provided, and strengthens throttling, cut-off effect, improves working life.
Technological scheme of the present invention is: this throttling stop valve comprises valve body, valve gap, valve rod, spool, soft wave pipe, valve seat and handle, and handle is contained in the top of valve rod, and valve rod runs through valve gap, and valve gap links to each other with valve body; Valve rod is provided with convex shoulder, its lower end has the endoporus nut to match with the valve core link rod outside thread, valve core link rod is fixed on the valve gap support with the position shelf that is provided with copper sheathing, and the valve core link rod lower end is connected with frustoconic shape cut-off flap, and cut-off flap lower end is connected with rhombus tubbiness throttling flap; The soft wave pipe is contained in the inner chamber of valve body, and its upper end is contained between valve gap and the valve body, and the lower end is connected with frustoconic shape cut-off flap.
Described spool is made of frustoconic shape cut-off flap and rhombus tubbiness throttling flap, and frustoconic shape cut-off flap lower end coats the soft seal pad and matches with the horizontal seal face of valve seat; Rhombus tubbiness throttling flap is contained in the valve seat diamond passages, and the upper end of rhombus bucket abdomen is enclosed construction, and every side plane is equipped with rectangular through holes, matches with valve seat diamond passages sealing surface.
On the described valve gap one-way valve is housed.
The present invention has following beneficial effect: the one, and valve rod is not with fluid contact and can inject oiling agent by one-way valve, avoided the dead or stubborn motionless phenomenon of rust, and switch is flexible; The 2nd, the soft seal pad of frustoconic shape cut-off flap contacts fully with the horizontal seal face of valve seat, and rhombus tubbiness throttling flap contacts fully with the sealing surface of valve seat diamond passages, makes existing pair of cutoff function of spool, and throttling action is arranged again.The 3rd, the through hole that fluid passes through rhombus tubbiness throttling flap flows out, and its flap and sealing surface of seat are not directly washed away by fluid, are difficult for causing damage.Above-mentioned functions guarantees that throttling stop valve has good sealing effect, the characteristics of long service life.

Embodiment
Doing the present invention below in conjunction with the drawings and specific embodiments further describes.Throttling stop valve handle 9 is contained in the top of valve rod 1, and valve rod 1 runs through valve gap 2, and valve gap 2 links to each other with valve body 3; Valve rod 1 is provided with convex shoulder 11 and can not moves up and down with handle 9 control valve rods 1, and valve rod 1 lower end endoporus nut 12 matches with valve core link rod 5 outside threads 51, and valve rod 1 rotating drive valve core link rod 5 moves up and down, and the band movable valve plug is implemented valve switch; The position shelf 52 that valve core link rod 5 usefulness are provided with copper sheathing 53 is fixed on the valve gap support 21, and valve core link rod 5 lower ends are connected with frustoconic shape cut-off flap 6, and cut-off flap 6 lower ends are connected with rhombus tubbiness throttling flap 7; Soft wave pipe 4 is contained in the inner chamber of valve body 3, and its upper end is contained between valve gap 2 and the valve body 3, and the lower end is connected with frustoconic shape cut-off flap 6.
Spool is made of frustoconic shape cut-off flap 6 and rhombus tubbiness throttling flap 7, and its frustoconic shape cut-off flap 6 lower ends are provided with coating soft seal pad 61 and match with the horizontal seal face 81 of valve seat; Rhombus tubbiness throttling flap 7 is contained in the valve seat diamond passages, the upper end closed structure matches with passage inner sealing surface 82, have cutoff function, each side rectangular through holes 71 of rhombus tubbiness throttling flap 7 its rhombus bucket abdomens cooperates with valve seat diamond passages sealing surface 82, forms the throttling effect.
One-way valve 22 is housed on the valve gap 2 communicates with valve pocket, oiling agent injects valve pocket by one-way valve 22, makes valve rod 1, valve core link rod 5 obtain continuous lubrication.
