Description
Technical Field
The utility model relates to a governing valve technical field particularly, relates to a start formula governing valve in advance.
Background
The regulating valve is also called a control valve, and in the field of industrial automation process control, the final control element for changing the process parameters of medium flow, pressure, temperature, liquid level and the like by power operation through receiving the control signal output by a regulating control unit. Generally consisting of an actuator and a valve. If according to the characteristics of the stroke, the regulating valve can be divided into a straight stroke and an angular stroke; the valve opening device can be divided into a pneumatic regulating valve, an electric regulating valve and a hydraulic regulating valve according to power used by an actuating mechanism matched with the valve opening device, the valve can be opened only by the aid of the actuating mechanism in the valve opening process of the conventional regulating valve, and the valve opening device is particularly obvious in a high-pressure environment. An effective solution to the problems in the related art has not been proposed yet.

In the figure: 1. the valve comprises a cage, a valve core 2, a valve rod 3, a limiting block I4, a base 5, a spring 6, a limiting block II 7, a through hole II 71, a through hole II 8, an upper valve cover 9, a cavity I10, a cavity II 11, a through hole I12 and a through hole III.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art all belong to the protection scope of the present invention.
As shown in figure 1, according to the embodiment of the utility model provides a pre-opening type regulating valve, including cage cover 1 and case 2, cage cover 1 upper end fixedly connected with upper valve cover 8, be equipped with valve rod 3 in the case 2, but 2 axial displacement of the relative case of valve rod 3, 3 bottom fixedly connected with bases 5 of valve rod, base 5 is the T font, base 5, upper valve cover 8, cage cover 1 and case 2 can constitute cavity one 9, be equipped with through-hole one 11 on the case 2, both sides are equipped with stopper one 4 and stopper two 7 respectively about being located base 5 in the case 2, be equipped with spring 6 between base 5 and the stopper two 7, stopper two 7 bottoms are equipped with through-hole two 71, through-hole two 71 and through-hole one 11 can communicate.
The utility model discloses a concrete embodiment, be equipped with the cushion on stopper 4 and the 5 contact surfaces of base, when base 5 displacement to with stopper 4 contact, the cushion plays the shock attenuation and reduces mechanical friction's effect.
In a specific embodiment of the present invention, the spring 6 is made of spring steel, and the object made of spring steel can recover its original shape even if it is significantly bent or twisted.
For the convenience of understanding the technical solution of the present invention, the following detailed description will be made of the technical solution of the present invention through a specific use mode.
When the valve is in a closed state, the flange part at the bottom of the T-shaped base 5 seals one end of the through hole III 12, the through hole III 12 is a blind hole, the valve core cage 1, the valve core 2, the upper valve cover 8 and the base 5 form a sealed cavity I9, and the spring 6 is compressed at the moment; when the valve is to be opened, the valve rod 3 is driven by the actuating mechanism to be lifted upwards slightly, the valve rod 3 and the base 5 are lifted upwards under the action of the tensile force of the actuating mechanism and the elastic force of the spring 6, the base 5 is lifted, the cavity II 10 and the cavity I9 are communicated with each other through the through hole III 12, the through hole II 71 and the through hole I11 at the moment, a balance valve type is formed, the valve rod 3 continues to be lifted upwards at the moment to drive the valve core 2 to move upwards together, and the valve is located in the balance valve type cavity, so that the tensile force required to be output by the actuating mechanism can meet the valve opening function without being large.
To sum up, with the help of the utility model discloses an above-mentioned technical scheme through increase spring and through-hole and then form balanced valve formula in the case, can realize adjusting the case switching with less pulling force, can choose for use less actuating mechanism, practices thrift the cost, improves the life cycle of valve body inner part to the actual life of extension valve body.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
