Blowdown valve using butterfly valve, butterfly valve is called flap valve, is a kind of regulating valve simple in structure, available for low pressure pipeline medium
Switch control, butterfly valve refer to closure member（Flap or butterfly plate）For disk, one kind of open and close is reached around valve shaft rotation
Valve；Butterfly valve can be used for the empty gas and water of control, steam, various Korrosionsmediums, mud, oil product, liquid metal and radiating medium etc.
The flowing of various types fluid.Butterfly valve can also play switch control action in evaporated crystallization device, but there are one to ask
Topic is exactly：Crystalline solid can be set on the butterfly plate of butterfly valve so that butterfly valve opens difficulty, has to tear pipe flange open sometimes, ability
Blowdown operation is completed, is made troubles to blowdown work.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies of the prior art and provide a kind of scientific structure design to close
Reason, can facilitate unlatching, and crystallization is not easy frozen plug, moreover it is possible to carry out a kind of evaporated crystallization device of internal washing.
Realize that the utility model provides following technical scheme：A kind of evaporated crystallization device, mainly including heater, crystallizer
And blowdown valve, described heater one end are connected with crystallizer, the other end is connected with blowdown valve, the crystallizer other end and blowdown
Valve connects, and the blowdown valve is upper exhibition valve, and the upper exhibition valve includes valve body, valve rod, flap, valve seat, handwheel, vomit pipe and cleaning
Pipe；The valve rod passes through valve body, and one end connection handwheel, other end connection flap, the valve body top is equipped with valve seat, valve body lower portion
Equipped with more than two vomit pipes；The vomit pipe is arc；A vomit pipe is equipped with cleaning pipe wherein, and the cleaning pipe is inclined
It sets obliquely, cleaning pipe is equipped with rubber diaphragm with vomit pipe junction；The rubber diaphragm is circle, and diameter is straight with cleaning pipe
Footpath is identical；Radial gap is carved on the rubber diaphragm；The flap is identical with valve seat joining place diameter, and the two joining place is neat
It puts down and equipped with sealing rubber ring, forms vertical configuration.
Preferably, the valve outer wall also wraps up insulation jacket, the vomit pipe side wall is equipped with heat source import.
Preferably, the valve rod outer wall coating antifriction alloy；The valve interior wall coats corrosion-inhibiting coating.
Preferably, the cleaning pipe angle of inclination is 15 ° ~ 45 °.
The usefulness of the utility model：First, the vomit pipe of arc can ensure blowdown without dead angle；Multiple vomit pipes
Design, can be carried out at the same time blowdown, pipeline is not easy to plug；Second, cleaning pipe is set on a vomit pipe wherein, due to valve body
Interior each vomit pipe is logical, convenient for being cleaned in valve body；3rd, rubber diaphragm can effectively prevent no sewage backflow from entering
Cleaning pipe；4th, flap is identical with valve seat joining place diameter, and the joining place of the two flushes, and forms vertical configuration, prevents crystallization from condensing
In joining place；5th, insulation jacket is wrapped up on the outside of valve body, is also beneficial to prevent solution from crystallizing.
