Abstract

The utility model relates to a metering control valve comprising a ball valve. A flow equipment provided in the sphere channel through hole comprises an impeller, an impeller shaft, an impeller base the other end of which is designed as a cone for conductivity. A coloured body or a metal diaphragm is provided at outer edge of the impeller. Small circular holes are provided directly under the major valve body and the sphere. The small circular hole of the major valve body has thread thereon and has a hollow protective sleeve arranged therein. The hollow protective sleeve has light conducting fibre or a sensor mounted therein. The coloured body at outer edge of the impeller or the metal diaphrag rotates with the impeller. The light conducting fibre or the sensor receives signals and transfers to a single chip processor and liquid crystal display for displaying metering and remote controlling on the spot. This utility model has useful effects of: media flow metering can be performed when the ball valve is opened, and the metering will be stopped when the ball valve is closed, the metering and the controlling are performed synchronically, the metering control valve has a small volume, a compact structure and can prevents magnetic field or artificial magnetic disturbance. The contact position contacting with corrosive medium in the flow meter can be manufactured of corrosion resistant engineering plastics.

Description

Measuring control valve

Technical field

The utility model relates to a kind of valve, relates in particular to the measuring control valve that a kind of rate-of flow metering and control valve are integrated.

Background technique

At present, industrial measuring apparatus has metering pump, flowmeter or the like, but all be that metering system and control system are two independent devices, metering is returned in metering, control is returned in control, thereby cause metering to be difficult to synchronously with control, and producing the inaccurate phenomenon of metering all has generation, and simultaneously big industrial Chemical Manufacture Korrosionsmedium metering will adopt measuring tank to measure, cause the equipment investment cost height, occupied ground is big, measure inaccurate disadvantage.

Summary of the invention

The purpose of this utility model is that to solve industrial medium metering be two independent device with control, provide a kind of metering and control synchronously, accurate measurement, easy to operate measuring control valve.

The utility model solves the problems of the technologies described above one of technological scheme of being adopted: measuring control valve, comprise ball valve, in the spheroid runner through hole of ball valve, be provided with a cover flow meter, it comprises impeller, impeller shaft, the impeller bearing, the impeller bearing the other end is designed to conical as guide functions, the impeller outer edge design has the colour solid that eats for optical fiber, have small sircle hole under main valve body and the spheroid, the small sircle hole of main valve body is threaded, hollow sheath is installed in the small sircle hole, and hollow sheath is installed optical fiber, and the impeller outer edge colour solid is with wheel rotation, optical fiber eats, and passes to single-chip microcomputer and LCD and can show metering and telecontrol on the spot.

The utility model solves the problems of the technologies described above two of the technological scheme that adopted: measuring control valve, comprise ball valve, in the spheroid runner through hole of ball valve, be provided with a cover flow meter, it comprises impeller, impeller shaft, the impeller bearing, the impeller bearing the other end is designed to conical as guide functions, the impeller outer edge design has the metal diaphragm that eats for sensor, have small sircle hole under main valve body and the spheroid, the small sircle hole of main valve body is threaded, hollow sheath is installed in the small sircle hole, the hollow sheath sensor installation, the impeller outer edge metal diaphragm is with wheel rotation, sensor eats, and passes to single-chip microcomputer and LCD and can show metering and telecontrol on the spot.

The beneficial effects of the utility model are: when ball valve is opened, media flow is measured at once, ball valve is closed and is promptly stopped metering, metering and control are carried out synchronously, and volume is little, compact structure, prevent magnetic field and artificial magnetic disturbance, and according to the metering needs of various Korrosionsmedium, can with in the flowmeter with the Korrosionsmedium contact position, adopt corrosion resistant engineering plastics manufacturing.

Embodiment

Be described in further detail below in conjunction with accompanying drawing, metering of the present utility model is achieved in that synchronously that with control the utility model is that a cover flow meter is set in the medium through hole of spheroid 14, and it comprises that 2 impeller bearings 2, impeller 4, impeller shaft 3, impeller bearing positioning retainer ring 20 are fixed in the spheroid through hole.Threaded small sircle hole 6 was installed hollow sheath 7, with gland nut 11 O-ring seals 10 is compressed sealing under design had small sircle hole 5, main valve body 1 under main valve body 1 and the spheroid 14, impeller 4 outer rim colour solids 12 or metal diaphragm 13 are aimed in the hollow sheath termination, with impeller outer edge interval 1mm, hollow sheath 7 is wanted printing opacity, heatproof, the good nonmetallic material manufacturing of corrosion resistance.Impeller bearing 2 centers are furnished with bearing hole, and impeller bearing 2 another sides are designed to conical as guide functions.15 is valve seal seat F4 among the figure, and 16 is auxiliary valve body, and 19 is valve rod.

Scheme 1: impeller 4 outer rim girths 1/3～1/2 design chromoplast 12, optical fiber 8 is installed in the hollow sheath 7, the colour solid 12 on the impeller is aimed in the termination, when ball valve is opened, colour solid 12 is along with the impeller rotation on media flow, the impeller 4, optical fiber 8 promptly eats, and passes to single-chip microcomputer and LCD and reaches demonstration on the spot and long-distance metering control.

Scheme 2: the design of impeller 4 outer rim girths 1/3～1/2 has metal diaphragm 13, sensor 9 to be installed in the hollow sheath 7, metal diaphragm 13 is aimed in the termination, when ball valve is opened, metal diaphragm 13 passes to single-chip microcomputer and LCD and reaches demonstration on the spot and long-distance metering control along with impeller 4 rotations, sensor 9 promptly eat from metal diaphragm 13 on the media flow impeller 4.

The keying of ball valve is carried out automation control according to the needs of metering, and the open/close executor of ball valve is respectively manually, worm gear, pneumatic, electronic etc., presses customer requirements and disposes.

In the utility model 17 for access plate, with four screw 18 fixing seals, specifically act on and be: need not dismantle ball valve, can check, overhaul replacing flow meter in the spheroid.Specific operation are to close ball valve, and the fluid passage faces peep hole in the spheroid, unclamp four retaining screws, 18 dissembling inspection blind patch 17 and can flow device check, check replacing, load onto access plate 17 then, and fixing seal can recover to use.
