Abstract
The utility model provides a liquid pipeline column-type rotary valve capable of controlling jacket heating and heat preservation automatically. The utility model is characterized in that the liquid pipeline butterfly valve comprises a valve body and a power-drive device, and the drive device has two drive modes, i.e. an air-powered drive mode and an electricity-powered drive mode. The valve normally has an opening state and a closing state, the rotation angle is 90 degrees, the drive device is connected with the valve body through a flange and a bracket, and the bracket can slow down the temperature of the valve body to be transmitted to the drive device. The valve body comprises a valve jacket and a column-type valve core, and the valve body has a movable fit with the valve core. The valve is connected with the external part through a flange. The heating jacket can perform heating through various modes of steam, heat-conducting oil and the like. The utility model has the advantages that the installation and maintenance are simple and convenient, the processing is easy, the material consumption is low, the control mode is reasonable, the switching speed is high, the closure is excellent and the pressure resistance is high.
Description
Technical field:
The utility model relates to the automatic controlling plumbing fixtures valve of a kind of high temperature media.Particularly a kind of automatic control overcoat heat tracing fluid pipeline pillar rotary valve.
Technical background:
At present, the structure of the automatic controlling plumbing fixtures valve of the high temperature media of China is various, and the fluid pipeline valve arrangement form that adds hot jacket mostly is stopcock, and this structure lacks reliable control mode, because pipeline valve is to medium purity requirement strictness.As containing impurity, very easily leak in the medium.
Owing to lack reliable automatic control mode, have following defective: 1, the control stroke is longer, easily breaks down.2, complex structure is manufactured difficulty.3, equipment volume is big, heavy, consumes big.4, it is difficult to install, overhaul.
Summary of the invention:
The purpose of this utility model is the defective that exists in the above-mentioned technology, and a kind of automatic control overcoat heat tracing fluid pipeline butterfly valve is provided.This rotary valve has solved high temperature media fluid pipeline valve and has realized convenient control automatically.Can effectively control stroke, avoid fault to take place.Making not only simple in structure is easy, and equipment volume is little, and is in light weight, easy for installation, easy-maintaining.
The purpose of this utility model is achieved in that it is made up of valve body and Power Drive Unit two-part, and drive unit has pneumatic and electronic two kinds of driving mode; The valve normality has the open and close two states, and angle of swing is 90 degree, it is characterized in that drive unit is connected with support by flange with valve body, and support can make the temperature of valve body slow down and pass to drive unit.Valve body is made up of valve overcoat and pillar spool, is movingly between valve body and the spool.Valve adopts flange to connect with outside the connection.Adding hot jacket can adopt steam or the multiple mode of heat conduction wet goods to heat.
The utility model has the advantages that installation and maintenance are simple, convenient.Processing manufactures simple and easy, materials consumption is little.Control mode is reasonable, and switching speed is fast, encapsulation good, withstand voltage height.

Fig. 2 is the plan view of Fig. 1
Fig. 3 is the left view of Fig. 1
Fig. 4 is Fig. 3 C-C sectional view
Embodiment:
By Fig. 1-4 as can be known, valve body 1 upper end is by combined connection component 4,5 connect as one with link press span 2, valve body 1 lower end links together by combined connection component 12 and rear flange 9, valve handle 6 is installed on link press span 2, valve handle 6 is connected with drive controller 3 by flat key, link press span can make the temperature of valve body slow down and pass to drive unit, liquid also can be that gas flows into from A or B, flow out, electrical signal by external given can make drive controller 3 actions, the actuator of drive controller 3 rotates by the key that is installed on the central shaft 10, and axle sleeve 7 is enclosed within on the axle 10, and the endoporus of axle sleeve 7 links to each other with axle, external diameter links to each other with forward flange 8, central shaft 10 and spool 11 are fixed together, and when central shaft 10 rotated, spool 11 was also along with rotation, thereby, reach the purpose of opening and closing valve.The seal of valve is to realize by the cooperation between valve body and the spool.By the hole on the valve body 13,14 can will add deep fat or steam inject in the valve body, add deep fat or steam circulates in valve body, thereby reach the purpose of valve body heating, and can make valve body keep temperature constant.
