Abstract
The utility model discloses an automatic heat-dissipating high-temperature-resistant stop valve which comprises a handle, a valve rod nut, a packing press cover, packing, a valve rod, a valve point, a connecting pipe nut, a connecting pipe, a connecting pipe gasket, a main valve body, a sealing gasket and cooling fins, wherein the handle is arranged on the valve rod; the valve rod nut is sleeved on the valve rod to be functioned in lifting the valve rod and tightly pressing the packing press cover; the cooling fins are sleeved on the valve rod; and the lower ends of the cooling fins are connected with the valve body. The cooling fins play a role of quick heat dissipation, therefore, the packing is protected, the service life of valve is prolonged, the temperature of the whole valve and the handle is reduced, and the valve is convenient to operate; the valve point is riveted at the bottom of the valve rod, and hard alloy is sprayed on the surface, so that the wear-resistant property, the temperature resistance and the resistance of medium flow impact are improved; the sealing gasket is positioned between the cooling fins and the valve body so as to play a role of sealing; the packing is sleeved between the valve rod nut and the cooling fins; the connecting pipe is connected with the valve body by the connecting pipe nut; and the connecting pipe gasket is positioned between the connecting pipe and the main valve body to seal the connecting pipe and the valve body. Therefore, the service life of the valve can be prolonged; and the sealing precision of the valve body can be ensured.
Description
Technical field
The utility model belongs to valve and makes the field, relates to a kind of valve that under the HTHP situation, uses, and is specifically related to the high temperature resistant stop valve of a kind of automatic heat radiation.
Background technique
Stop valve extensively applies to be used for doing the connection pressure gauge in the industrial processes such as chemical industry, oil, metallurgy, mine, electric power, the energy, environmental protection, measures and government pressure; And as required, to the pipeline discharging dirt of fed sheet of a media, the stop valve in the existing techniques is because quick heat radiating effect in time; The protection filler improves working life, reduces bulk temperature; So that operation brings insecurity to production, particularly valve body is in high-temperature high-pressure state for a long time; Influence greatly validity, sealing and working life and the Safety performance of valve, and, in actual use; Operator because the HTHP situation of stop valve can not be accomplished timely alleviation, have increased operator's danger when operation.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, long service life, and operation is easily reliable, and safety rate is high, the high temperature resistant stop valve of the automatic heat radiation that can in time lower the temperature.
The purpose of the utility model is to realize through following technological scheme.According to the high temperature resistant stop valve of a kind of automatic heat radiation of the utility model, comprise handle, Stem Mut, Gland, filler, valve rod, valve point, union nut, adapter, adapter pad, main body, gasket seal, radiating fin.It is characterized in that suit radiating fin on valve rod plays the quick heat radiating effect, the protection filler; Improve working life, reduce bulk temperature, be convenient to operation; Be riveted on the valve point of the bottom of valve rod, the surface is coated with cemented carbide, increases wear-resisting; Heatproof and anti-current stroke are operated very easy, and more safe and reliable.
The high temperature resistant stop valve of described a kind of automatic heat radiation, wherein handle is contained on the valve rod, on the Stem Mut suit valve rod, acts on the up-down of valve rod and compresses the effect of Gland; Radiating fin is sleeved on the valve rod, and the lower end is connected with main body, and described radiating fin plays the quick heat radiating effect, the protection filler; Improve working life, reduce the temperature of integral body and handle, be convenient to operation, the valve point is riveted on the bottom of valve rod; The surface is coated with cemented carbide, increase wear-resisting, the impact of heatproof and anti-rate-of flow; Gasket seal seals between radiating fin and main body, and filler is sleeved between Stem Mut and the radiating fin.Adapter is connected with main body through union nut, takes over pad between adapter and main body, sealing adapter and main body.
The high temperature resistant stop valve of described a kind of automatic heat radiation, the big I of its specification are according to practical operation and the market demand and change.Adapter can be communicated with pipeline or instrument according to demand.
The usefulness of the high temperature resistant stop valve of a kind of automatic heat radiation of the utility model is, owing at suit radiating fin on valve rod, play the quick heat radiating effect, the protection filler; Improve working life, reduce bulk temperature, be convenient to operation; Be riveted on the valve point of the bottom of valve rod, the surface is coated with cemented carbide, increases wear-resisting; Heatproof and anti-current stroke are operated very easy, and more safe and reliable.Simultaneously, do not influence original service behaviour of valve, and can prolong the working life of valve, guarantee the sealed precision of valve body.
