Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of large latus rectum stop valve, belongs to valve class application.
Background technique
Valve is extensive use in industry, has the following disadvantages in actual use: only permitted the medium one-way flow, directivity is arranged during installation; The valve cost is high, function singleness; When fluid resistance is large, valve opening and close difficultly is unsuitable for frequent switch motion; When being used for granular, viscosity flowing medium large, easily coking, sealing effect is poor.
The model utility content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of large latus rectum stop valve is provided, and simple in structure, rapid operation is easy, and adjusting function is good, is applicable to the conveying of medium.
The technological scheme that its technical problem that solves the utility model adopts is: described large latus rectum stop valve, it is characterized in that comprising valve body, balloon and tracheae, and be provided with balloon in the valve body, balloon is connected to source of the gas by tracheae.
Wherein:
Described valve inner is fixed with support ring, and tracheae passes the center hole of support ring and is fixedly connected with support ring.The means of fixation of support ring and valve body has multiple, and the utility model preferably adopts by interference fit support ring is assemblied in the valve body, fixing tracheae in the center hole of support ring.
Described valve inner is fixed a baffle ring, and balloon is between baffle ring and support ring.When realizing cut-off, by the fixed support effect of baffle ring and support ring, realize the two-way stop of fluid, effectively prevent balloon play in valve body.
Described valve body is to be threaded connection by main valve body and valve gap to form, and support ring is fixed in the main valve body, and baffle ring is fixed between main valve body and the valve gap.The Placement of main valve body and valve gap is varied, Placement in the utility model between main valve body and the valve gap preferably adopts and is threaded, and the end that valve gap connects main valve body is provided with step, baffle ring by the step locking main valve body on, fixing reliable, field-strip is convenient.
Solenoid valve and pressure communication device are installed on the described tracheae, on the valve outlet pipeline flowmeter are set, flowmeter and solenoid valve are connected to control gear, come adjust flux by the switch motion of controlling solenoid valve.During balloon inflation, closed electromagnetic valve when pressure reaches setting pressure stops inflation, and the valve complete shut-down is realized cutoff function, this pressure can according to the caliber of valve body and set through the pressure of fluid; During the balloon exhaust, solenoid valve is opened, and closed electromagnetic valve when pressure arrives negative pressure stops exhaust, valve wide open, and fluid reaches peak rate of flow, and this pressure can be set according to the pressure of pipeline neutral body; Flowmeter detecting flux signal, control gear is regulated the action of electromagnetism according to the flux signal of detecting, realizes flow regulating function by inflation, exhaust to balloon.
Divided by upper outside, the utility model can also be preferably as follows scheme:
Described control gear preferably adopts PLC, and is easy to operate, is widely used;
Described balloon can be selected different materials according to different media, is applied to the conveying of various fluids.
Working principle and process:
Tracheae connects source of the gas, and the solenoid valve action is to " ON " position, and balloon begins inflation, when reaching the force value of setting, stops inflation, realizes cutoff function; The solenoid valve action is to " OUT " position, and balloon begins exhaust, when pressure is negative pressure, stops exhaust, reaches peak rate of flow.
Flowmeter detecting flux signal on the pipeline, when underfed, signal feed back is to PLC, the action of PLC instruction control solenoid valve is to " OUT " position, and the balloon exhaust arrives when setting flow, flux signal feeds back to PLC, and the action of PLC instruction control solenoid valve stops exhaust to " OFF " position; When flow was excessive, signal feed back was to PLC, and the action of PLC instruction control solenoid valve is to " ON " position, and balloon inflation arrives when setting flow, and signal feed back is to PLC, and the action of PLC instruction control solenoid valve stops inflation to " OFF " position; So realize flow regulating function.
The beneficial effect that the utility model has is:
Large latus rectum stop valve described in the utility model, balloon is contained in the valve body, and is simple in structure, without the one-way flow requirement; Realize valve event by inflation, exhaust to balloon, rapid operation is easy, and adjusting function is good, easily realizes automation control; Balloon is selected different materials, can be suitable for the conveying of medium.
