Abstract
The utility model relates to a small pneumatic balanced-type sleeve regulating valve. The small pneumatic balanced-type sleeve regulating valve is characterized in that a pneumatic actuator is arranged on the upper portion of a valve body and is fixedly connected with an upper valve deck through a connecting nut, a support, double-end studs and hexagon nuts; a pressing plate, a packing gland, an upper lining, packing, a lower lining and a packing spring are sequentially arranged in the upper valve deck to form a pneumatic membrane actuator; a valve plug component is arranged in a lower sleeve in the valve body and is connected with the valve body through a sealing gasket II in a sealed mode; the upper valve deck is fixedly connected with the valve plug component through double-end studs, hexagon nuts, the upper valve deck, a sealing gasket I, an upper sleeve and a balancing sealing ring in a sealed mode to form a low-choked-flow sleeve regulating mechanism. The small pneumatic balanced-type sleeve regulating valve has the advantages of being low friction coefficient, free of adhesion, light in weight, small in size, high in flow rate, applicable to occasions where low noise and large differential pressure are required, and capable of being widely used for automatic control and remote control in the petroleum industry, the chemical industry, the metallurgy industry, power stations, the building material industry, the glass industry and the light industry.
Description
Technical field
The utility model belongs to a kind of liquid conducting pipes valve, particularly the small-sized new type of pressure-balanced cage type control valve of a kind of pneumatic essence.
Background technique
At present, domestic on liquid conducting pipes valve, the regulating valve that tradition arranges, there is the problems such as weight is large, volume is large, flow is little, due to resistance to wear and anti-extrusion performance poor, therefore, be not suitable for automatic control and the telecontrol of the industries such as oil, chemical industry, metallurgy, power station, building materials, glass and light industry.
Summary of the invention
The utility model has overcome the defect of above-mentioned existence, object is for improving resistance to wearing and anti-extrusion performance of valve, the automatic control and the telecontrol that realize the industries such as oil, chemical industry, metallurgy, power station, building materials, glass and light industry, provide a kind of pneumatic essence small-sized new type of pressure-balanced cage type control valve.
The small-sized new type of pressure-balanced cage type control valve content Description of the pneumatic essence of the utility model:
The small-sized new type of pressure-balanced cage type control valve of the pneumatic essence of the utility model, is characterized in that: the small-sized new type of pressure-balanced cage type control valve of pneumatic essence is comprised of air bladder spring acuator and low choked flow sleeve controlling mechanism; Top at valve body is provided with pneumatic actuator, by attaching nut, support, stud, hexagon nut, be fixedly connected with bonnet, in bonnet, be provided with successively pressing plate, Gland, on lining, filler, lower lining and packing spring form air bladder spring acuator; Valve plug parts are arranged in the lower sleeve in valve body, valve plug parts and valve body are tightly connected by sealing gasket II, and bonnet and valve plug parts are sealedly and fixedly connected and are formed low choked flow sleeve controlling mechanism by stud, hexagon nut, bonnet, sealing gasket I, upper bush and balance seal ring.
The small-sized new type of pressure-balanced cage type control valve of the pneumatic essence of the utility model, adopt the sealing of balanced seal circle to have to resistance to wear and anti-extrusion characteristics has low coefficient of friction, NA characteristic, the feature lightweight, volume is little, flow is large, be applicable to require the occasion that noise is low, pressure reduction is large, can be widely used in automatic control and the telecontrol of the industries such as oil, chemical industry, metallurgy, power station, building materials, glass and light industry.
