Abstract
The utility model relates to a three-way change valve which comprises a valve body, a valve plate, a valve rod and seal rings, wherein one end of the valve rod is vertically connected with one side of the valve plate; the valve body is composed of three chambers which are arranged axially along the valve rod, and valve seats are respectively arranged between the middle chamber and the adjacent chambers; the seal ring is arranged on the valve seat; one side of each cavity is provided with a valve port; the valve plate is positioned in the middle chamber; the other end of the valve rod passes through one end of the chamber in sealing slide and is connected with an air cylinder piston rod arranged at the end of the chamber. The utility model has good tightness; the service life of products is long, and the average of the service life of products is larger than one million times; change-over time is smaller than 1 second; the utility model has high temperature resistance, which can make the valve gate be used for a long time in the state of 300 DEG; three chambers are designed independently, which has high structural strength.
Description
Technical field
The utility model relates to a kind of novel three-way diverter valve, is mainly used in the high-temperature gas reversing mechanism and the residual neat recovering system of metallurgy, petrochemical industry oven.
Background technique
The selector valve of existing such use is general to use two to cut valve soon and realize that valve quantity is many, poor sealing performance, during high temperature distortion big, control loaded down with trivial details, working life weak point.
Summary of the invention
The purpose of this utility model just provides a kind of three-way diverter valve, uses two to cut valve soon and realize that valve quantity is many with the selector valve that solves existing such use, poor sealing performance, during high temperature distortion big, control loaded down with trivial details, working life weak point problem.
The technical solution of the utility model is: comprise valve body, valve plate, valve rod and seal ring, one end of valve rod is vertically connected on valve plate one side, described valve body is made up of three cavitys along the valve rod axially-aligned, respectively be provided with a valve seat between cavity in the middle and the adjacent cavity, on valve seat, be provided with seal ring, be equipped with valve port in a side of each cavity; Described valve plate is positioned at the middle part cavity, and the other end sealing slip of described valve rod passes an end of cavity and is connected with a cylinder piston rod that is connected this cavity end.
Described seal ring adopts the aviation special (purpose) rubber to make.
Slip surface between described valve rod and the cavity adopts copper sheathing to be connected.
The utlity model has following advantage:
(1) adopt aviation special (purpose) rubber circle seal ring, valve rod has partly adopted copper sheathing to be connected with casing, and these technologies have guaranteed the sealability of this product.This product under 2 kilograms of pressure, half an hour the pressure loss less than 0.1%, and these performance index of domestic other existing like product are about 4%.
(2) product service life is on average greater than 1,000,000 times, and this of domestic other existing like product performance is then less than 400,000 times.
(3) turn around time is less than 1 second, and domestic existing like product its of average out to is 3 to 5 seconds turn around time at present.
(4) structure of this three-way diverter valve is alternately passed through cold and hot gas, and valve is used under 300 degree states for a long time.
(5) three chamber independent design, the structural strength height.
Description of drawings
Fig. 1 is a general structure schematic representation of the present utility model.
Embodiment
Referring to Fig. 1, the utility model comprises cylinder 1, valve body 2, valve plate 3, valve rod 5 and seal ring 4, and valve body 2 is made up of three cavitys that are arranged in a linear, and respectively is provided with a valve seat between cavity in the middle and the adjacent cavity, is provided with seal ring 4 on valve seat; Side at each cavity is equipped with valve port 6.Described valve plate 3 is positioned at the middle part cavity, and an end of valve rod 5 is vertically connected on a side of valve plate 3, and the other end of valve rod 5 slides along the length direction sealing of valve body 2 and passes an end of valve body 2, and is connected with a piston rod that is connected the cylinder 1 of valve end.Support 7 is connected between valve body 2 and the cylinder 1.Described seal ring 4 adopts the aviation special (purpose) rubber to make.
Seal sliding surface between described valve rod 2 and the valve body 2 adopts copper sheathing 8 to be connected.
Working principle of the present utility model is as follows:
The piston rod of cylinder 1 drives valve plate 3 and moves up and down valve port 6 conductings on middle part and top when valve plate 3 falls among Fig. 1.And valve plate 3 mentions when upper, the valve port mutual conduction of middle part and bottom, thus realized the conversion of path.The utility model is used in particular for the frequent alternately conversion and control to dibit two-way pipeline, when this application, adopt two the utility model, two valve ports of upper and lower part are distinguished parallel connection respectively as suction port and air outlet, and two middle part valve port active chambers connect the control that can realize above-mentioned alternate conduction.Its application example is the application in ladle baking facility.
