Abstract
The utility model belongs to the technical field of chemical equipment and in particular relates to an improved novel structure V-shaped ball valve which is used under a solid particle containing slurry environment. The novel structure V-shaped ball valve comprises a valve body, a valve spool and a valve seat. The novel structure V-shaped ball valve is characterized in that the valve spool is a ball spool with a V-shaped opening in the surface; a compression sealing ring is screwed onto the valve body through threads, a spring seat and a compression spring are arranged on the valve seat, and the compression sealing ring is pressed through the spring seat and then seals the end surface of the valve seat; the spring seat is fixedly arranged on the valve seat through a circle of socket hexagonal screws; a limiting step is arranged on the spring seat. The novel structure V-shaped ball valve has the advantages that the sealing requirement is satisfied, the torque of the valve can be effectively improved and the torque is reduced by 30-50 percent relative to the torque of similar valves; moreover, the tiny change of an electric signal value of the valve can be reflected in the form of the action of the valve and the return difference of the valve is reduced.
Description
Technical field
The utility model belongs to technical field of chemical, is specifically related to a kind of for containing the V-type ball valve that improves structure under solid particle slurry environment.
Background technique
Be used in the adjusting V-type ball valve of chemical industry, for containing the structural type under solid particle slurry environment, widely different with traditional V-type ball valve.Traditional V-shaped valve structure is, after valve seat and V ball are adjacent to, can not regulate pretightening force, assembling maintenance difficult, and the sealability of valve relies on machining accuracy to guarantee completely.
Summary of the invention
The purpose of this utility model is for above-mentioned present situation, and a kind of improved new structure V-type ball valve proposing.
The utility model is achieved like this: new structure V-type ball valve, comprise valve body, spool and valve seat, it is characterized in that described spool is for the surperficial ball core that has V-type mouth; On described valve body, by screw thread, be screwed with compresses seal, valve seat is provided with spring seat and Compress Spring, after compresses seal compresses by spring seat by valve seat end face seal; Spring seat is fixed on valve seat by a circle socket head screw; Spring seat is provided with limited step.
Normally, V-type ball valve of the present utility model also comprises the known Gland in this field, packing press ring, filler, valve rod, the axis of guide, axis of guide neck bush and bottom etc.
The utility model improves structure V-type ball valve, at ball wicking surface, has V-type mouth.By being conventionally pressed in seal ring on valve seat, changing and be placed on valve body, for the end face of seal valve seat, advantage is to avoid being delivered to valve seat for the power of compresses seal, changes into spring seat and pushes down seal ring, after seal ring is compressed, by valve seat end face seal, prevent medium leakage.Trim ring is screwed on valve body with screw thread.With a circle socket head screw, to spring seat, exert pressure, the spring on valve seat has pretightening force, and valve seat is attached on V ball, and can be used for compensating expanding with heat and contract with cold under high-temperature condition, and the step of limited location on spring seat contributes to the pretightening force of control spring.
When the utility model is used by control room to the electrical signal of 4-20mA to valve positioner, positioning work piece converts the electrical signal to air pressure signal, makes actuator drive valve, valve can regulate within the scope of 0 to 90 °.The sensitivity regulating is the key of check valve performance, and the sensitivity of adjusting directly affects the steady of Production in Chemical Plant.
This new structure V-type ball valve, when meeting seal request, can effectively improve the moment of torsion of valve, than valve torque of the same type, reduces 30%--50%.Can make valve can be reflected to immediately the action of valve in the small variation of value of electrical signals, reduced the return difference of valve simultaneously.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model embodiment's structural representation.
In figure, 1-Gland; 2-packing press ring; 3-valve rod; 4-filler; 5-axis of guide neck bush; 6-valve body; 7-Compress Spring; 8-compresses seal; 9-spool; 10-valve seat; 11-socket head screw; 12-spring seat; The 13-axis of guide; 14-bottom.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in detail.
Embodiment: new structure V-type ball valve as shown in Figure 1, mainly comprises valve body 6, spool 9 and valve seat 10, to be described spool 9 have V-type mouth ball core for surface to its main feature; On described valve body 6, by screw thread, be screwed with compresses seal 8, valve seat 10 is provided with spring seat 12 and Compress Spring 7, after compresses seal 8 compresses by spring seat 12 by valve seat 10 end face seals; Spring seat 12 is fixed on valve seat 10 by a circle socket head screw 11; Spring seat 12 is provided with limited step.
In embodiment, also comprise the valve fittings that this field is conventional, Gland 1, packing press ring 2, valve rod 3, filler 4, axis of guide neck bush 5, the axis of guide 13 and bottom 14.
Embodiment in use by control room to the electrical signal of 4-20mA to valve positioner, positioning work piece converts the electrical signal to air pressure signal, makes actuator drive valve, valve can regulate within the scope of 0 to 90 °.
