Description
Technical field
The utility model belongs to valve field, particularly about a kind of fixing ball valve.The adjustment type that the utility model is applicable to the large discharge medium pipelines such as petrochemical industry, natural gas, water controls ball valve.
Background technique
In large discharge medium transport pipe-line systems such as petrochemical industry, natural gas, town water supplies, intelligent control valve is generally used to regulate, control flow and the pressure of output medium.Ball valve is because its structure is simple, open-close convenient, it is the valve types more generally used, but the spheroid due to ball valve has the circular channel with valve diameter, in adjustment process, changes in flow rate is nonlinear, poor to the linearity of Flow-rate adjustment, especially on the city supply water pipeline of large discharge, Flow-rate adjustment precision is very low.And when spheroid aperture is less, velocity of medium is comparatively large, high-speed Medium washes away comparatively large to spheroid passage, easy erosion spheroid.
Summary of the invention
The purpose of this utility model is the shortcoming existed for prior art, provides that a kind of Flow-rate adjustment linearity is good, degree of regulation is high, the Flow-rate adjustment type fixing ball valve that medium is little to the erosion of spheroid passage.
The technical solution of the utility model comprises valve body, valve seat, spheroid, valve rod, gland, final controlling element, and valve rod lower end is fixedly connected with spheroid, and upper end is connected with final controlling element through gland, and valve seat is arranged in valve body inlet passage; Mainly controlling device is set in spheroid passage, this controlling device is made up of fixed cover, Level tune plate, vertical adjusting plate, the periphery close-fitting of fixed cover is arranged in spheroid passage, Level tune plate is fixedly mounted in fixed cover passage along fixed cover channel direction level, vertical adjusting plate is fixedly connected with along fixed cover channel direction and Level tune plate are mutually vertical, and Level tune plate and vertical adjusting plate are shaped with some adjustment holes; Between valve body import and outlet passage, install diverter valve, the latus rectum of this diverter valve is the integral multiple of valve body latus rectum.
In above technological scheme, Level tune plate has two pieces, and symmetry is arranged on the inwall of fixed cover channel centerline both sides.
In above technological scheme, Level tune plate and vertical adjusting plate both sides of the edge are v-shaped structure, and its V-arrangement opening is towards spheroid channel entrance direction.
The utility model advantage is compared with prior art in spheroid passage, arrange the controlling device be made up of fixed cover, Level tune plate, vertical adjusting plate, reduces medium washing away spheroid vias inner walls, improves the linearity of Flow-rate adjustment; Between valve body import and outlet passage, diverter valve is installed, realizes the Flow-rate adjustment of small-bore modulating valve to large discharge pipeline, improve Flow-rate adjustment precision.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1 valve body, 2 valve seats, 3 Level tune plates, 4 vertical adjusting plates, 5 fixed covers, 6 glands, 7 valve rods, 8 spheroids, 9 diverter valves.
Embodiment
Flow-rate adjustment type fixing ball valve as shown in Figure 1, comprise valve body 1, valve seat 2, spheroid 8, valve rod 7, gland 6, final controlling element, valve rod 7 lower end is fixedly connected with spheroid 8, upper end is connected with final controlling element through gland 6, valve seat 2 is arranged in valve body 1 inlet passage, valve seat 2 adopts floating structure, and spheroid 8 adopts fixing spherical structure.In spheroid 8 passage, controlling device is set, this controlling device is made up of fixed cover 5, Level tune plate 3, vertical adjusting plate 4, the periphery of fixed cover 5 and spheroid 8 vias inner walls interference fit, Level tune plate 3 is fixedly mounted on the vias inner walls of fixed cover 5 along fixed cover 5 channel direction level, the i.e. plane of Level tune plate 3 and valve rod 7 central axis, namely under ball valve full-gear, Level tune plate 3 forms plane orthogonal with valve rod 7 center line and valve body 1 channel centerline.Vertical adjusting plate 4 is fixedly connected with along fixed cover 5 channel direction and Level tune plate 3 are mutually vertical, and namely under ball valve full-gear, vertical adjusting plate 4 is with valve rod 7 center line and valve body 1 plane parallel that channel centerline is formed or overlap.Level tune plate 3 and vertical adjusting plate 4 are shaped with some adjustment holes, and the quantity of adjustment hole, aperture, distribution density require design according to valve body 1 channel diameter and tuning linearity.Between valve body 1 import and outlet passage, install diverter valve 9, the latus rectum of this diverter valve 9 is integral multiples of valve body 1 latus rectum, and its multiple value is determined according to the size of pipe-line system flow, realizes the Flow-rate adjustment of small-bore modulating valve to large discharge pipe-line system.
Level tune plate 3 has two pieces, and symmetry is arranged on the inwall of fixed cover 5 channel centerline both sides, and and plane-parallel.
Level tune plate 3 and vertical adjusting plate 4 both sides of the edge are v-shaped structure, and its V-arrangement opening is towards spheroid 8 channel entrance direction.V-arrangement angle is according to the design of valve body 1 channel diameter, and Level tune plate 3 and vertical adjusting plate 4 also can adopt rectangle structure, can select design according to the linearity of Flow-rate adjustment.Level tune plate 3 and vertical adjusting plate 4 are at two end faces of spheroid 8 channel direction all in spheroid 8 passage, and namely the end face of Level tune plate 3 and vertical adjusting plate 4 can not stretch out outside spheroid 8 passage.
