Abstract

The utility model relates to a conical valve. The utility model is characterized in that a valve body (3) is assembled with a set of sealing conical sleeves (2) and sealing conical bodies (4) forming a conical surface fit; the sealing conical body (4) is connected with a rotary axle (6); the valve body, the sealing conical sleeve and the sealing conical body form a cylindrical through hole on the same pipe axle line; the valve body (3) is sealed by a valve cap (1). The utility model has the advantage of long service life; under the condition of adopting the same material, the service life of the conical valve is several times or even tens of times of a ball valve; first, the integral valve is integrally sealed, and second, the rotary valve cap pushes the sealing conical body after the sealing abrasion to obtain the effect of the abrasion compensation, especially that the abrasion process is the running-in process; the valve cap is slightly screwed after the abrasion to obtain multiple abrasion compensation; the service life of each regulation is equivalent to the service life of one ball valve.

Description

Cone valve

The utility model relates to the circulation and the valve that ends usefulness of controlling liquid in the pipeline, gas.

Best valve all is to adopt ceramic plate sealing (as the water valve series of the three glasss of cleaners and polishes factories productions in Beijing) at present, it has wear-resisting characteristics, particularly there is a slice to move up and down along shaft axis, so wearing and tearing time break-in just the time, thereby can compensate as wearing and tearing, just in this point, be quite long its sealing life, but the sealing of the axle of operation unit can not be adopted same technology, its life-span and common valve are as good as, and total life-span of a valve is the most short-life that part of decision by its each sealed department, this shows, overall life still can not prolong, also have a problem in addition, any one valve has plural independent sealing part at least, and sealing part is many more, guarantee that overall life is long just difficult more, this has also caused the life-span of existing valve really not prolong.

The purpose of this utility model is at above shortcoming, proposes that a kind of cost is low, the life-span is long, the valve of superior performance, and both can be used for also can be used for pipe end in the pipeline way, and is applied widely.

The technical solution of the utility model is: assembling one secondary conical surface cooperates in valve body sealing tapered sleeve and seal cones, seal cones connects a running shaft, valve body, sealing tapered sleeve and seal cones form a cylindrical hole on same conduit axis, valve body closes with a cap seal.

The utility model cost of production is low, at first be material and other valves do not have what special requirement and the sealing tapered sleeve be plastics, have only seal cones to use and be easy to the metallic material (as copper) that any surface finish is processed, all can freely selecting of other according to different height class, it two is that processing cost is low, have only the conical surface and the seal cones conical surface corresponding of two annulus of sealing tapered sleeve that surface requirements is arranged with it, but because of tapered sleeve is injection molded, so only mould is had requirement, do not influence batch process, in addition because tapering is little, the requirement that has reduced the precision of processing (promotes seal cones downwards by ball when plug screw is tightened, the positive pressure that I guess slight some power just can produce enough the annulus conical surface of sealing tapered sleeve makes its distortion, reach the effect of sealing), assembling is simple, and whole assembling one is spanner, a bottle opener just can be finished, the cylinder appearance that particularly seals tapered sleeve do not have the circular ring projection and make press-fit also easy.Biggest advantage is the life-span speciality, adopting under the situation of equivalent material, the life-span of life-span cone valve is the several times of ball valve and even tens of times, and the whole valve of the first is the one sealing, the rotation valve gap promotes seal cones behind its two sealing wear, reaches the effect of compensate for wear.Particularly Mo Sun process is the process of break-in, can reach repeatedly wear compensation so that wearing and tearing backs only need gently screw valve gap, and every accent life-span once just is equivalent to the life-span of a ball valve.Applied widely, can make the valve that pipeline valve midway also can be done outlet end, can make little valve and also can do turnover pipe and the outlet mouth that the Special valve of big valve, particularly particular matter can be joined different outward appearances, be easy to produce in enormous quantities and the seriation of product.

Concrete structure of the present utility model and mode of execution are provided by the following drawings.

Accompanying drawing 1 is an assembling front view

Accompanying drawing 2 is Fig. 1 plan views

Among the figure, 1-valve gap, 2-sealing tapered sleeve, 3-valve body, 4-seal cones, 5-ball, 6-running shaft, 7-handle.

The details of the utility model mode of execution is described below with reference to the accompanying drawings.

Agent structure of the present utility model can come into plain view by erection drawing 1.Process valve body and will seal tapered sleeve and be fitted in total valve body with metal ceramic, (tapered sleeve is that employing is injection molded to mating face filling sealer, at its junction plane, form some circular little bulge loops along its cylndrical surface, filler and deformation sealing when conveniently press-fiting) with total valve body.Require sealed thing from total valve body A end pipeline, not leak in the top cylindrical cavity of total valve body B end and total valve body by its sealing surface.In seal cones (processing) the dress sealing tapered sleeve with metal, the sealed circular ring conical surface fluid-tight engagement of the inner the right and left of the conical surface of seal cones and stuffing box gland, when closing, the seal cones middle part is cylindrical to be in vertical position by axis with total valve body conduit axis, make sealed thing not enter the B end by main valve A end, and no matter seal is in unlatching or closes situation, the top conical surface of seal cones seals circular conical surface top with the both sides of stuffing box gland inside all the time and keeps engaging closely, prevent that sealed thing from entering in the cylindrical cavity on stuffing box gland top, thereby guarantee that handling portion does not leak.The situation of the cylndrical surface on top and seal upper end inner cylindrical surface contact (suitable loose fit) and play the guiding role on the seal cones.The waist shape piece of running shaft inserts in the kidney slot on seal cones top, and two ends are fixed with sunk screw, makes the little axle of rotation play up and down.Valve gap and main valve body and function scyewed joint, valve gap bottom surface and seal cones end face are processed with arc groove, and the ball of packing in the groove plays a part to reduce to rub and power transmission.Therefore valve setpoint is manually opened, not have too fast speed, thereby puts into ball with the arc groove that common turning is processed and get final product, certain available plane bearing replacement, and can add shock mount herein.This also belongs to protection domain of the present utility model.
