Abstract
The utility model relates to a regulating valve, comprising a valve body and a valve rod; wherein, a top of the valve body is provided with an air pressure inlet; the valve rod is in an inverted T shape, a bottom of the valve rod is provided with a block matched with the valve rod; an upper part of the valve rod is provided with a spring; and an upper part of the spring is provided with an air film. The regulating valve of the utility model consists of the valve body, the valve rod, the spring, the air film, the block, and so on, and has the advantages of simple structure, low cost, less fault, and easy maintenance. The regulating valve of the utility model realizes open of the valve by utilizing a downward thrust from an air pressure signal to the air film to drive the valve rod to move downwards, maintains balance through an elastic force of the spring, and can regulate flow of the valve by controlling the size of the air pressure signal.
Description
Technical field
The utility model relates to a kind of valving, specifically a kind of modulating valve.
Background technique
In the automatic control system of modern chemical industry factory, because the correct distribution and the control of mobile liquids and gases are depended in the production of factory, so modulating valve plays crucial effect in automatic control system.Modulating valve generally adopts power type or electric liquid type to realize distant control at present, but these two kinds of control modes all have complex structure, cost is high and troublesome shortcoming, in the small-sized electric control system, is difficult to a large amount of uses.
The model utility content
The purpose of the utility model just provides a kind of modulating valve, to solve complex structure and the high problem of cost that existing modulating valve exists.
The utility model is achieved in that a kind of modulating valve; Include valve body and the valve rod that is located at valve inner; Have the air pressure inlet at said valve body top, said valve rod is an inverted T shape, and the sprue that matches with valve rod is arranged in said stem bottom; Top at said valve rod is provided with spring, is provided with air film on said spring top.
The utility model is made up of the parts such as valve rod, spring, air film and sprue that are arranged in the valve body, and it is simple in structure, and cost is low, thereby has guaranteed that fault is few, even be out of order also easy-maintaining.The utility model is through air pressure signal the downward thrust of air film to be driven valve rod to move downward the unlatching that realizes valve, and keeps balance through the elastic force of spring, can accomplish the adjusting of valve flow through the size of control air pressure signal.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, air pressure inlet, 2, air film, 3, spring, 4, valve rod, 5, valve body, 6, sprue.
Embodiment
As shown in Figure 1, the utility model includes valve body 5, has air pressure inlet 1 at the top of valve body 5; Be provided with air film 2 at the top of valve body 5; Below air film 2, be connected with spring 3, spring bottom is connected with the valve rod 4 of inverted T shape, is provided with the sprue 6 that matches with valve rod in the bottom of valve rod 4.
The work engineering of the utility model is: at first, air pressure signal is fed valve body 5 from air pressure inlet 1, air pressure produces a downward thrust on air film 2, and driving spring 3 moves down with valve rod 4, and this modulating valve is opened.Simultaneously, spring 3 is compressed the back air film 2 is produced a reaction force that makes progress, when the reaction force of spring 3 equates with the thrust of air pressure signal on air film 2, and valve rod 4 stop motions, modulating valve promptly is in stable opening state.The enter the mouth pressure of pressure signal at 1 place of air pressure is big more, and the thrust on air film 2 is also just big more, and the decrement of spring 3 is that the aperture of this modulating valve is also with regard to corresponding increase.
