Abstract
The utility model relates to a dual-pass angle type high-pressure throttling stop valve, which is composed of a valve seat, a valve cap, an upper valve rod, a lower valve rod, a padding box, a padding device, a padding cover, a valve handle, a connecting device, a shim, a fastening element, etc., such as the show of picture 1. The utility model is characterized in that the lower part of the lower valve is provided with an outer conical sealing surface which is upward. The lower surface of the padding box is provided with an upward inner conical sealing surface. Two sealing surfaces are sealed with each other, and therefore, the medium of a valve door and the padding device of the valve door are isolated. The medium leaking into the padding device is prevented, and the service life of the padding device is extended. In the process of normally using the valve door can change the device with voltage.
Description
The utility model relate to a kind of prevent that valve packing from leaking and can be in normal using process the having a double meaning angie type High-pressure Throttle Stop Valve of replace with pressure valve packing.
Usually the angie type High-pressure Throttle Stop Valve is made up of valve seat, valve gap, valve rod, stuffing box, filler, follower, valve handle, joiner and fastening piece etc.In the filler chamber between stuffing box and valve rod filler is housed, borrows follower that filler is compressed and play seal action, stop medium along the outside seepage of valve rod thereby take.Yet filler is very easily aging and wearing and tearing by the use of a period of time, cause the medium of valve to leak out from filler, influence ordinary production, also befouling environment.The existing throttling stop valve structure not only medium of valve is easy to contact with filler, it is aging and working life is short to quicken filler, maximum shortcoming be can't be in the ordinary production using process filler of the aging and wearing and tearing of replace with pressure, could change filler during the valve of stop work and production maintenance regularly, it is huge causing the economic loss that suffers in the production thus.
The purpose of this utility model provides a kind of medium that can prevent valve from the outside seepage of valve packing, can prolong filler working life and can be in the ordinary production using process the having a double meaning angie type High-pressure Throttle Stop Valve of replace with pressure filler.
For achieving the above object, the utility model is achieved in that at cylindrical conical seal (contact) face that makes progress of lower valve rod bottom making, make a upwards inner conical sealing surface below stuffing box, the cylindrical conical seal (contact) face of lower valve rod and the inner conical sealing surface of stuffing box can be sealed to each other.When counterclockwise rotating valve handle, valve rod moves up, and valve opening is during to maximum position, the pipeline communication, and medium can flow through.And the sealing of the inner conical sealing surface of cylindrical conical seal (contact) face that lower valve rod makes progress and stuffing box bottom, thereby make interior medium of valve and valve packing isolated, prevent medium to the filler seepage, prolonged filler working life, can the replace with pressure filler in the normal using process of valve.
Brief description of drawings
Fig. 1 is a sectional view of the present utility model.
Fig. 2 is a partial enlarged drawing of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in detail:
The utility model mainly is made up of valve seat (1), valve gap (6), upper valve rod (14), lower valve rod (2), stuffing box (3), filler (5), follower (8), valve handle (9), joiner (12) pad (4) and fastening piece etc.Stuffing box (3) is housed in the valve seat (1), lower valve rod (2) is housed at stuffing box (3).Stuffing box is to be connected with the attaching nut and to compress by valve gap (6), guarantees the sealing of two surface of contact of valve seat and stuffing box.Filler (5) and lining (7) and follower (8) are housed in stuffing box (3), and compress filler by regulating bolt (13) locking.Filler and lower valve rod and stuffing box are closely cooperated and seal, thereby the drive part that makes valve forms a sealing system, guarantees that the medium of valve can not leak out from two surface of contact of valve seat (1) and stuffing box (3) and lower valve rod and stuffing box two surface of contact.Valve handle (9) is housed on upper valve rod (14), and upper valve rod (14) is connected with valve gap (6) by screw thread, and upper valve rod is connected by joiner (12) with lower valve rod, forms a complete regulating system like this.In lower valve rod (2) bottom a cylindrical conical seal (contact) face that is directed downwards is arranged, a downward inner conical sealing surface is also arranged on the sealing seat of valve seat (1), and guarantee that the downward cylindrical conical seal (contact) face in lower valve rod bottom and the inner conical sealing surface of the sealing seat of valve seat can seal the Kai Heguan of realization valve.Feature of the present utility model is the sealing surface (15) that a cylindrical taper that makes progress is arranged in lower valve rod (2) bottom, a upwards inner conical sealing surface (16) is arranged below stuffing box (3), and guarantee that the cylindrical conical seal (contact) face that this inner conical sealing surface and lower valve rod bottom make progress can seal mutually, thereby can guarantee that the medium of valve and valve packing are isolated, can be in ordinary production be used the replace with pressure valve packing.
When clockwise direction rotated valve handle, lower valve rod (2) moved along the direction shown in the arrow (11), is pressed at last on the sealing seat of valve seat, and valve is in closed condition, and medium just is cut off.When counterclockwise rotating valve handle, when valve rod when arrow (10) direction moves to the valve opening maximum position, the outer cone sealing surface that stem lower portion makes progress seals mutually with female cone sealing surface on the stuffing box, make the medium and the valve packing of valve isolated, thereby can be in the normal using process of valve the replace with pressure filler, realized opening and the pass effect of valve.This simple in structure, reliable operation is closed tightly, is convenient to the replace with pressure filler.Feature of the present utility model is applicable to various forms of stop valves.
Claims (1)
1, a kind of having a double meaning angie type High-pressure Throttle Stop Valve, form by valve seat, valve gap, upper valve rod, lower valve rod, stuffing box, filler, follower, valve handle, joiner, pad and fastening piece etc., it is characterized in that having the sealing surface of a cylindrical taper that makes progress in the lower valve rod bottom, an inner conical sealing surface that makes progress is arranged below stuffing box, and the sealing surface of the cylindrical taper that lower valve rod makes progress can be sealed to each other with the sealing surface of the inner conical of stuffing box.
