Abstract
The utility model discloses a kind of air bag valve valve opening and closing control system, belong to technical field of valve control.This air bag valve open-shut control system is mainly consisted of pipeline connection compressed air filtering pressure reducing valve, one-way throttle valve, air accumulator and control electromagnetic valve, when power failure occurs, electromagnetic valve dead electricity, electromagnetic valve valve is opened, compressed air enters in air bag valve from controlling source of the gas, and air bag valve closes；When source of the gas decompression, controlling pressure switch I detects signal, makes electromagnetic valve power-off, electromagnetic valve valve open, and the compressed air in air accumulator enters in air bag valve, makes air bag valve be kept closed；Additionally, control the alarm pressure switch II that the lateral between electromagnetic valve and air bag valve is provided with, the air pressure of air bag valve can be monitored, change the air bag valve sebific duct of gas leakage in time, it is further ensured that air bag valve is at closure state when electricity, gas fault, improves the safety of technical process.
Description
Technical field
This utility model belongs to technical field of valve control, it is specifically related to one and can control air bag valve valve opening and closing flexibly, especially when electricity, gas fault occur, can guarantee that air bag valve valve is closed, ensures the air bag valve valve opening and closing control system of technical process safety.
Background technology
Air bag valve is a kind of anti-wear performance and the most excellent valve of decay resistance, clean water experiment average life is at 200,000 times, being the favorable substitutes of the valves such as conventional ball valve, butterfly valve, diaphragm valve, in mine, metallurgy, medicine, construction implement and sewage treatment industry be all widely used.Under normal circumstances, air bag valve is dependent on compressed-air actuated pressure compression air bag and realizes valve Guan Bi, and after discharging gas, valve is opened.When electricity, gas fault, air bag valve is in normally open because of out of hand, it is impossible to meet the demand that most air bag valve needs to be kept closed under electricity, gas failure condition.It addition, the sebific duct as runner is consumable accessory in air bag valve, often there is the generation of gas leak phenomenon, if changing not in time because detecting, it may appear that valve leakage phenomenon, causing technical process out of control.
Utility model content
The purpose of this utility model is to solve above-mentioned technical problem, it is provided that a kind of air bag valve valve opening and closing control system that air bag valve valve can be made to be kept closed under electricity, gas failure condition.
For reaching above-mentioned purpose, this utility model is by the following technical solutions: a kind of air bag valve valve opening and closing control system, including compressed air filtering pressure reducing valve, this compressed air filtering pressure reducing valve is provided with controlling pressure switch I, and it is sequentially connected with one-way throttle valve and air bag valve, it is sequentially provided with air accumulator between one-way throttle valve and air bag valve and controls electromagnetic valve, all being connected by pipeline between each parts.
The volume of above-mentioned air accumulator is 750-1500mL, and gas capacity is more than 2 times of the most gases used amount of air bag valve valve closing.
In order to monitor the air pressure of air bag valve, in air bag valve, sebific duct leaks air and changes in time after phenomenon, the generation of anti-leak-proof valve phenomenon, and this utility model is provided with alarm pressure switch II on the lateral controlled between electromagnetic valve and air bag valve.
This utility model, compared to prior art, has the advantages that
(1) the air bag valve open-shut control system of this utility model, mainly it is made up of by pipeline connection compressed air filtering pressure reducing valve, one-way throttle valve, air accumulator and control electromagnetic valve, when power failure occurs, electromagnetic valve dead electricity, electromagnetic valve valve is opened, compressed air enters in air bag valve from source of the gas, makes air bag valve valve close；When source of the gas decompression, controlling pressure switch I detects signal, makes electromagnetic valve power-off, electromagnetic valve valve open, and the compressed air in air accumulator enters in air bag valve, makes air bag valve valve be kept closed.
(2) the alarm pressure switch II that this utility model is provided with on the lateral controlled between electromagnetic valve and air bag valve, the air pressure of air bag valve can be monitored, change the air bag valve sebific duct of gas leakage in time, it is further ensured that air bag valve is at closure state when electricity, gas fault, improves the safety of technical process.
Accompanying drawing explanation
Fig. 1 is annexation schematic diagram of the present utility model.
Reference: 1, source of the gas；2, compressed air filtering pressure reducing valve；3, controlling pressure switch I；4, one-way throttle valve；5, air accumulator；6, electromagnetic valve；7, alarm pressure switch II；8, air bag valve.
Detailed description of the invention
In order to be more fully understood that this utility model, with detailed description of the invention, it is described further below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of air bag valve valve opening and closing control system, including compressed air filtering pressure reducing valve 2, this compressed air filtering pressure reducing valve 2 is provided with controlling pressure switch I 3, and it is sequentially connected with one-way throttle valve 4, air accumulator 5, electromagnetic valve 6 and air bag valve 8, all connected by pipeline between each parts；Wherein, being provided with lateral between electromagnetic valve 6 and air bag valve 8, this lateral is provided with alarm pressure switch II 7.
The situation that this utility model controls air bag valve keying is as follows:
(1) normal when source of the gas 1, when electromagnetic valve 6 is not charged, the a-b position conducting of electromagnetic valve 6, compressed air enters air bag valve 8, makes air bag valve 8 valve closing；When electromagnetic valve 6 is charged, the b-c position conducting of electromagnetic valve 6, air bags, make air bag valve 8 reset and turn on, valve is opened.
(2) when there is power failure, electromagnetic valve 6 power-off, the a-b position conducting of electromagnetic valve 6, compressed air enters in air bag valve 8, keeps valve closing.
(3) when source of the gas 1 decompression, controlling pressure switch I 3 detects signal, electromagnetic valve 6 power-off concatenated with it, and the a-b position conducting of electromagnetic valve 6, the gas in air accumulator 5 enters air bag valve 8 pressurize, and makes air bag valve 8 be closed.Additionally, the alarm pressure switch II 7 being between electromagnetic valve 6 and air bag valve 8 on lateral detects when the air pressure of air bag valve 8 does not reaches the minimum pressure needed for valve closing for a long time, judge that its sebific duct leaks gas, thus send alarm signal, staff is reminded to change sebific duct in time, to ensure the safety of technical process.
Claims (2)
1. an air bag valve valve opening and closing control system, including compressed air filtering pressure reducing valve (2), this compressed air filtering pressure reducing valve (2) is sequentially connected with one-way throttle valve (4) and air bag valve (8), it is characterized in that: compressed air filtering pressure reducing valve (2) is provided with controlling pressure switch I (3), it is sequentially provided with air accumulator (5) and electromagnetic valve (6) between one-way throttle valve (4) and air bag valve (8), is all connected by pipeline between each parts.
