Description
Technical field
The utility model relates to a kind of purifying and dedusting and gathers dust to use in control apparatus and control the valve that the air channel opens and closes.
Background technique
Now most popular air-valve is the function simple device of control pipeline air quantity and blast on the market, because function singleness usually affects its function because dust accumulation is stopped up in the process of using, reduced its stability in use, even the impact of breaking-up equipment is produced, and causes unnecessary loss.
The model utility content
The purpose of this utility model is to provide a kind of Novel composite air duct valve and not only has the function of controlling pipeline blast and air quantity, but also has the wind direction conversion function, coordinate the positive-negative air-blowing of deduster, realize self deashing function, kept the operation stability of equipment.
After the utility model is installed and used, air draft and two operating functions of deashing are rolled into one, thereby the effect of being independent of each other is carried out in every kind of functional independence work step by step.
The technical solution of the utility model is as follows:
A kind of compound air duct valve, its outside is valve shell, it is characterized in that: valve shell is divided into upper and lower two-part, top is perpendicular cone cylinder wide at the top and narrow at the bottom, perpendicular cone cylinder upper end open is import, and the bottom is horizontal cylinder, and the lower end of perpendicular cone cylinder is connected with the sidewall of horizontal cylinder; Horizontal cylinder open end is outlet, the other end sealing of horizontal cylinder; The sidewall of perpendicular cone cylinder is passed in the blowback air channel, and blowback air channel inner port is positioned at perpendicular cone cylinder and opening upwards, blowback air channel inner port marginal position be lower than inlet edge, and blowback air channel external port is positioned at outside perpendicular cone cylinder and is horizontally disposed with; Be designed with vertical pull bar in valve shell, blowback air channel sidewall is passed on the top of pull bar, and the termination, top passes and connects with the back blow port sealing plate from blowback air channel inner port, and the back blow port sealing plate carries out shutoff to blowback air channel inner port; The pull bar bottom is designed with the exhaust port sealing plate, and the exhaust port sealing plate carries out shutoff to perpendicular cone cylinder lower end mouth; The piston rod outer end of the lower end of pull bar and cylinder is connected, and cylinder is fixed in the below of horizontal cylinder; Blowback air channel and cylinder are connected with valve shell is airtight.
Above-mentioned a kind of compound air duct valve is characterized in that: pull bar and blowback air channel joint are provided with guide sleeve; Horizontal nose circle closed end is designed with inspection socket.
During the work of this device, drive pull bar by cylinder piston rod and move up and down, the perpendicular cone cylinder of exhaust port sealing plate sealing end opening when pull bar moves to the upper end, blowback air channel inner port is opened, the conducting of back-blowing dedusting wind path; When pull bar moves to the lower end, the back blow port sealing plate is with blowback air channel inner port sealing, and perpendicular cone cylinder end opening is opened, dedusting air channel conducting.
The utility model utilizes rod member, sealing plate combination to realize the substep control function of air draft and deashing.Whole system work coordinates the comprehensive electric control system controls of my company's independent development, each actuation cycle continuous control.The blowback wind regime is selected, but can select the also rear air of choice for use deduster purification of ambient atmosphere air.As using in the winter time, outside air temperature is low, considers temperature constant in the workshop, and after optional deduster purifies, air enters the workshop, and blowback this moment wind regime selects the deduster purified gas can keep temperature constant in the workshop, and can improve deduster blowback effect.
The utility model advantage:
1, this valve is simple to operate, and it is convenient to control.
2, valve body manufacturing valency is low, occupy little space, and long service life.
3, this valve is applied widely, also use capable of being combined separately.
4, this valve seal property is strong, and applicable strong wind is depressed use.
5, realize self deashing function, kept the operation stability of equipment, removed labor cleaning's trouble from.
