Summary of the invention
The purpose of this utility model: in order to overcome the defect of prior art, this utility model provides the pneumatic Slow Close of a kind of butterfly valve and controls device, its simple in construction, can control the butterfly valve shut-in time well.
nullThe technical solution of the utility model: the pneumatic Slow Close of a kind of butterfly valve controls device，It is characterized in that: include air inlet pipe、First connecting line、Second connecting line、Cylinder，Inner chamber it is provided with in cylinder，Interior intracavity is provided with piston，Inner chamber is separated into the first cavity by piston、Second cavity，Piston is extended with the piston rod for being opened by butterfly valve when piston is to the first cavity direction motion and closed by butterfly valve when piston is to the second cavity direction motion in the first cavity，First connecting line and the connection of the first cavity，Second connecting line and the connection of the second cavity，The one-way throttle valve that gas throttles in when piston is to the second cavity direction motion to the second cavity it is also associated with on second cavity，Also include for controlling the electromagnetic valve that air inlet pipe turns on the second connecting line with the first connecting line conducting or air inlet pipe，Electromagnetic valve is arranged on air inlet pipe and the first connecting line、Between second connecting line.
Use technique scheme, when butterfly valve needs to open, it is passed through source of the gas by air inlet pipe, electromagnetic valve controls air inlet pipe and the second connecting line conducting, gas promotes piston to move to the first cavity direction in entering the second cavity, gas in first cavity is discharged through the first connecting line, thus is opened by butterfly valve through piston rod；When butterfly valve needs to cut out; electromagnetic valve controls air inlet pipe and the first connecting line conducting; gas enters in the first cavity; piston is promoted to move to the second cavity direction; gas in second cavity is discharged through the second connecting line; piston rod drives butterfly valve to realize quick closedown; now by one-way throttle valve, the gas in the second cavity can be carried out throttling buffering; realize the slowly closing of valve; so can carry out, by choke valve, the time that control valve is closed; eliminate the water hammer of pipeline, play the effect of protection pipe network system safety well.
Further setting of the present utility model: described air inlet pipe is provided with pneumatic triple piece.
Use above-mentioned further setting, in pneumatics, air filter, air relief valve and three kinds of source of the gas treatment elements of oil sprayer are fitted together referred to as pneumatic triple piece, filter in order to enter the gas source purification of pneumatic instrument and be decompressed to the bleed pressure that instrument supply is specified, thus ensure the stability that source of the gas enters, also avoid the impurity effect electromagnetic valve in source of the gas, cylinder, the service behaviour of one-way throttle valve.
Further setting of the present utility model: air inlet pipe is provided with the ball valve for controlling air inlet pipe switching.
Use and above-mentioned further arrange, air inlet pipe can be cut off, uses safer in emergency situations, facilitate.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model specific embodiment.
Detailed description of the invention
nullAs shown in Figure 1，The pneumatic Slow Close of a kind of butterfly valve controls device，Include air inlet pipe 1、First connecting line 2、Second connecting line 3、Cylinder 4，It is provided with inner chamber in cylinder 4，Interior intracavity is provided with piston 5，Inner chamber is separated into the first cavity 411 by piston 5、Second cavity 412，Piston 5 is extended with the piston rod 6 for being opened by butterfly valve when piston 5 is to the first cavity 411 direction motion and closed by butterfly valve when piston 5 is to the second cavity 412 direction motion in the first cavity 411，First connecting line 2 connects with the first cavity 411，Second connecting line 3 connects with the second cavity 412，The one-way throttle valve 7 that gas throttles in when piston 5 is to the second cavity 412 direction motion to the second cavity 412 it is also associated with on second cavity 412，Also include for control air inlet pipe 1 and the first connecting line 2 turns on or air inlet pipe 1 and the second connecting line 3 conducting electromagnetic valve 10，Electromagnetic valve 10 is two-position-five-way solenoid valve，Electromagnetic valve 10 is arranged on air inlet pipe 1 and the first connecting line 2、Between second connecting line 3.Air inlet pipe is connected with the first port 101 of electromagnetic valve 10, and the first connecting line 2 is connected with the 4th port 104 of electromagnetic valve, and the second connecting line 3 is connected with the second port 102 of electromagnetic valve, and the 3rd port 103 of electromagnetic valve, fifth port 105 port are exhaust port.
In this utility model specific embodiment, described air inlet pipe 1 is provided with pneumatic triple piece 8.In pneumatics, air filter, air relief valve and three kinds of source of the gas treatment elements of oil sprayer are fitted together referred to as pneumatic triple piece, filter in order to enter the gas source purification of pneumatic instrument and be decompressed to the bleed pressure that instrument supply is specified, thus ensure the stability that source of the gas enters, also avoid the impurity effect electromagnetic valve in source of the gas, cylinder 4, the service behaviour of one-way throttle valve 7.
In this utility model specific embodiment, air inlet pipe 1 is provided with the ball valve 9 for controlling air inlet pipe 1 switching.So can cut off air inlet pipe 1, use safer in emergency situations, convenient.
When butterfly valve needs to open, it is passed through source of the gas by air inlet pipe 1, the first port 101 controlling electromagnetic valve 10 turns on the second port 102,4th port 104 turns on fifth port 105, now air inlet pipe 1 turns on the second connecting line 3, gas promotes piston 5 to move to the first cavity 411 direction in entering the second cavity 412, gas in first cavity 411 is discharged through the fifth port 105 of the first connecting line 2, electromagnetic valve 10, thus through piston rod 6, butterfly valve is opened, now, one-way throttle valve ends, and does not play throttling action；When butterfly valve needs to cut out, the first port 101 controlling electromagnetic valve turns on the 4th port 104, second port 102 turns on the 3rd port 103, now, air inlet pipe 1 turns on the first connecting line 2, gas enters in the first cavity 411, piston 5 is promoted to move to the second cavity 412 direction, gas in second cavity 412 is through the second connecting line 3, 3rd port 103 of electromagnetic valve 10 is discharged, piston rod 6 drives butterfly valve to realize quick closedown, now by one-way throttle valve 7, the gas in second cavity 412 can be carried out throttling buffering, realize the slowly closing of valve, so can carry out, by choke valve, the time that control valve is closed, eliminate the water hammer of pipeline, play the effect of protection pipe network system safety well.
