Abstract
The utility model provides a high-temperature and high-pressure stop valve, which comprises a main body, a valve stem, a filling, a filling gland, a valve stem nut, a handle, a valve tip, a sealing gasket and radiating fins. The high-temperature and high-pressure stop valve is characterized in that the radiating fins are sleeved onto the valve stem for realizing the rapid heat radiation effect. Meanwhile, the filling is protected by the radiating fins, so that the service life of the filling is prolonged. The temperature of the integral body of the stop valve is reduced through the radiating fins, thereby facilitating the operation. The valve tip is riveted to the bottom of the valve stem and the surface of the valve tip is sprayed with cemented carbide. Therefore, the wear resistance, the temperature resistance and the anti-flow-impact performances of the valve tip are improved and the operation is very simple, safer and more reliable. The elevating of the valve stem is controlled and the filling gland is compressed tightly through the handle arranged on the valve stem and the valve stem nut sleeved onto the valve stem. The radiating fins are sleeved onto the valve stem and the lower ends of the radiating fins are connected with the main body. Therefore, the wear resistance, the temperature resistance and the anti-flow-impact performance are improved. The sealing gasket arranged between the radiating fins and the main body plays a sealing effect. The filling is sleeved between the valve stem nut and the radiating fins. Meanwhile, the original working performances of the valve are not influenced and the service life of the valve is prolonged. The sealing precision of the valve body is also 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 a kind of high temperature and high pressure cut-off valve.
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 and high pressure cut-off valve that can in time lower the temperature.
The purpose of the utility model is to realize through following technological scheme.
According to a kind of high temperature and high pressure cut-off valve of the utility model, comprise main body, valve rod, filler, Gland, Stem Mut, handle, valve point, 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.Described a kind of high temperature and high pressure cut-off valve, 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.
Described a kind of high temperature and high pressure cut-off valve, the big I of its specification are according to practical operation and the market demand and change, and the Placement of valve and pipeline has I.S.S, outside thread formula, FERRULETYPE.
The usefulness of a kind of high temperature and high pressure cut-off valve 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.
