Abstract
The utility model relates to a high temperature resistant hard alloy stop valve, comprising a valve cover, a valve body, a valve rod and a valve clack, wherein a sealing packing is arranged between the valve cover and the valve rod, a packing gland is arranged on the sealing packing, the valve rod and the valve clack are connected in a driving way, a support is also fixedly arranged on the valve cover, a valve rod nut is arranged in the support, the valve cover, the valve body and the valve clack are made of high-temperature resistant alloy steel, and a hard alloy layer is welded on the sealing surface of the valve body and the valve clack in a spraying way. The high-temperature resistant hard alloy stop valve has the beneficial technical effects that high temperature resistance performance is good, the sealing surface is wear-resistant, and the service life is long.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of high temperature resistant hard alloy stop valve.
Background technique
As everyone knows; Stop valve is a kind of valve commonly used, generally comprises valve body, valve rod, flap, valve gap etc., is provided with stuffing box packing between valve gap and the valve rod; Valve rod and flap are in transmission connection; On valve gap, also be installed with support, in support, be provided with the Stem Mut that is complementary with valve rod, stop valve is mainly made cut-out, throttling, distribution and change media flow direction and is used on pipeline.The stop valve of existing technology exists that resistance to high temperature is poor, sealing surface rapid wear, working life short shortcoming.
Summary of the invention
The utility model technical problem to be solved is the deficiency that overcomes existing technology, provides that a kind of resistance to high temperature is good, sealing surface is wear-resisting, the stop valve of long service life.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: high temperature resistant hard alloy stop valve, comprise valve gap, valve body, valve rod and flap, and be provided with stuffing box packing between valve gap and the valve rod; Stuffing box packing is provided with Gland; Valve rod and flap are in transmission connection, and on valve gap, also are installed with support, in support, are provided with Stem Mut; Described valve gap, valve body and flap are processed by high-temperature alloy steel, the sealing surface surfacing hard alloy layer of valve body and flap.The useful technique effect of the utility model is: because valve gap, valve body and flap processed by high-temperature alloy steel, and the sealing surface surfacing hard alloy layer of valve body and flap, thereby have that resistance to high temperature is good, sealing surface is wear-resisting, the advantage of long service life.
