Abstract
The utility model relates to a high-pressure throttle stop valve, comprising a valve body, a valve seat, a handle, a valve rod and a valve flap. The valve flap comprises a valve core and a hanging arm which is one-piece. The valve core is a reverse cone which is matched with the valve seat. A hanging hole which can rabbet the end head of the valve rod is arranged on the hanging arm. A hanging neck is matched and arranged at the end head of the valve rod. The hanging hole permits the hanging neck to rotate freely. The utility model is characterized in that the valve flap and the valve rod are arranged in separated; the valve core of the valve flap presents the reverse cone, and the friction isn't generated when the valve core of the valve flap is matched use with the valve seat. The phenomenon of seizure isn't also generated when the specific pressure is increased instantaneously, and the valve core has the section with alterable diameter. The high-pressure throttle stop valve can control the flow quantity of the high-pressure pulsating liquid as required, and the high-pressure throttle stop valve can avoid generating libration.
Description
The utility model belongs to throttling stop valve.
Traditional throttling stop valve in use easily produces the quality problems of leak fluid owing to the structure reason of flap with the valve seat that matches.When being used for the working environment of high-pressure pulsating fluid, also can take place the vibration and can't proper functioning.
The purpose of this utility model is the technological scheme that proposes a kind of High-pressure Throttle Stop Valve structure, to solve the problems referred to above that exist at present.
Content of the present utility model is a kind of High-pressure Throttle Stop Valve, comprise valve body, valve seat, handle, valve rod, flap, flap is made of the extension arm of lobe core and one, the lobe core is the inverted cone that cooperates with valve seat, hang arm and be provided with the suppending hole that to rabbet the valve rod termination, match and be provided with the extension neck in the valve rod termination, suppending hole allows to hang neck and rotates freely.Valve seat and valve body separated type are wholely set, and the valve seat embedding is crouched in valve body.In valve body, above valve seat, be provided with sealed stuffing box the time, press femalely, place stuffing box packing in the stuffing box, press mother to compress filler and stuffing box.
Characteristics of the present utility model are flap and valve rod split setting, and the spool of flap is inverted cone and valve seat and is used and does not produce friction, also can not produce when the instantaneous increase of specific pressure and kill phenomenon; And spool has the cross section that becomes diameter, can control the flow of high-pressure pulsating fluid on request and can avoid producing vibration.Another characteristics are Construction integrations that valve seat and valve body adopt separated type, can select suitable material and technology to make valve seat, valve body, and then valve seat embedded in the valve body become one with valve body; Valve seat can form desirable cooperating with the lobe core of flap, and valve body also can adopt multiple material and technology to make to replace the foundry goods of traditional heaviness.Another characteristics are sealed stuffing box to be set replace seal ring, can improve sealing effect.Simultaneously can also be at the bottom of the stuffing box to the position-limiting action that moved axially of flap.
Embodiment of the present utility model is as shown in drawings:
Accompanying drawing is that the master of the utility model High-pressure Throttle Stop Valve looks cross section view.
Number in the figure is represented:
1, handle, 2, valve rod, 3, press female, 4, stuffing box packing, 5, stuffing box, 6, seal ring, 7, valve seat, 8, flap hangs arm, 9, valve rod hangs neck, 10, flap lobe core, 11, inlet, 12, outlet, 13, valve body.
Accompanying drawing is specified the utility model in conjunction with the embodiments:
The flap of the utility model throttling stop valve is made of inverted cone lobe core 10 and extension arm 9 one, and lobe core 10 also can be down spheroid, and lobe core 10 matches with the inlet 11 of valve seat 7; Hang arm 8 and match with the extension neck 9 that valve rod 2 ends are provided with, and allow to hang neck and rotate freely, this routine fit system is will hang neck 9 to embed in the embedding hole that hangs setting on the arms 8 as shown in the figure, also can adopt alternate manner, for example universal joint mode etc.
The valve seat 7 and the valve body 13 of the utility model throttling stop valve are the Construction integrations of separated type, and valve seat 7 therefore selection manufacturing separately are to reach the requirement that matches with flap; Valve body 13 also can be processed separately, adopts new material, new process to reduce volume and raising usability.
The valve stem seal of the utility model throttling stop valve has adopted stuffing box 5 has been set, and filling material 4 usefulness press mother 3 to compress the mode of sealing in box.Its sealing effect is better than singly using seal ring.Stuffing box 5 bottoms also have the position-limiting action that flap is moved up.
For guaranteeing sealing effect, between valve seat 7 and valve body 13 scarfs and stuffing box 5 and valve seat 7, be provided with seal ring 6.
Handle 1 is contained in the upper end of valve rod 2.
The behaviour in service of the utility model throttling stop valve is: rotatable handle 1 drives valve rod 2 rotations and upper and lower moving, and makes that flap is upper and lower to be moved, and lobe core 10 can cooperate the flow or the shutoff inlet 11 of inlet 11 control fluids, thereby the control fluid enters outlet 12.
Adopt the utility model design can produce the series of valves product, in hyperbaric environment, use and to replace traditional product fully.
Claims (3)
1, a kind of High-pressure Throttle Stop Valve, comprise valve body, valve seat, handle, valve rod, flap, it is characterized in that flap is made of the extension arm of lobe core and one, the lobe core is the inverted cone that cooperates with valve seat, hang arm and be provided with the suppending hole that to rabbet the valve rod termination, match and be provided with the extension neck in the valve rod termination, suppending hole allows to hang neck and rotates freely.
2, High-pressure Throttle Stop Valve as claimed in claim 1 is characterized in that the valve seat embedding crouches in valve body.
