Description
Technical field
The utility model belongs to winding-up valve technology field, is specifically related to a kind of novel sealing structure High Temperature High Pressure blowing valve.
Background technique
In the last few years, along with progress and the development of coal chemical technology, how solving dust removal problem is a systematicness and critical problem, wherein one of technology utilizes a kind of special valve, by the valve of open frequency and instantaneous unlatching can be controlled, to control gas (can be nitrogen, steam etc.) the instantaneous winding-up power of High Temperature High Pressure, to purge dust; A kind of right-angle type High Temperature High Pressure pulse blowing valve is disclosed in patent 201320591463.0, comprise valve body, solenoid valve, two-way cylinder, valve rod, valve seal assembly, inlet end and outlet side, described valve rod is coaxial with described outlet side, described valve rod tail end connects described two-way cylinder, front end connects described valve seal assembly, described valve seal assembly comprise with the use of sealing flap and seal valve seat, described sealing flap front end arranges the guiding element through described seal valve seat.The utility model is by the two-way cylinder bidirectional-movement of electromagnetic valve, the lifting of band ovable valve stem, and band seal valve lobe is separated with closed with seal valve seat, thus realizes the effect of winding-up; And guiding element is set and not only can controls folding direction, the major skock of high temperature and high pressure gas can also be avoided; The hermetic unit of metal avoids diaphragm scaling loss in addition, and under ensureing the condition of elevated-temperature seal and good winding-up effect, its working life improves several times; Therefore need a kind of good sealing effect, keep in repair the easy and novel sealing structure High Temperature High Pressure blowing valve of low cost.
Model utility content
Technical problem to be solved in the utility model is not good for existing High Temperature High Pressure blowing valve sealing effect, and causes the phenomenon that maintenance difficult cost is high.
The technological scheme adopted for solving problem of the present utility model is: a kind of novel sealing structure High Temperature High Pressure blowing valve, comprise valve body, two-way cylinder, valve rod, sealing mechanism, inlet end and outlet side, described valve rod is coaxial with described outlet side, described valve rod upper end connects described two-way cylinder, run through described sealing mechanism to be connected with the sealing flap of described valve rod lower end, described sealing flap bottom arrange with the use of seal valve seat, described valve rod top hollow arranges refrigerating module.
Described sealing mechanism sets gradually dust cover, V-shaped seal ring, upper guide sleeve, radiating sleeve and lower guide sleeve from top to bottom along valve rod.
Arrange dust ring inside described dust cover, inside arranges oil lubrication system.
Inside described upper guide sleeve, rubber seal is set, arranged outside rubber seal.
The all sides of described radiating sleeve arrange Heat sink.
Described refrigerating module is condensation tube or cooling cylinder.
Described lower guide sleeve is self-lubricating high temp resisting alloy sheath.
Described rubber seal is O type rubber ring.
The utility model is compared with the sealing mechanism of existing right-angle type High Temperature High Pressure pulse blowing valve: arrange radiating sleeve on lower guide sleeve top, and radiating sleeve has the heat-dissipating space that certain length can provide enough, in radiating sleeve all sides, Heat sink is set, the temperature entering high-temperature gas in radiating sleeve can be reduced, realize preliminary cooling, also cooling water circulation can be set in radiating sleeve week side; The top of valve rod is hollow, can arrange the cooling of refrigerating module realization to valve rod top, providing suitable temperature conditions, carrying out cooling twice for arranging traditional rubber seal ring in valve rod; Because temperature is reduced within 110 DEG C by the refrigerating module on radiating sleeve and valve rod top, O type rubber ring is used, in the inner and outer of upper guide sleeve, all rubber seal is set, good seal action can be played, prevent the phenomenon that Air leakage detector occurs from gap; V-shaped seal ring is set on upper guide sleeve top and also can obtains good sealing when the upper and lower fast moving of valve rod, realize multiple security sealing; In order to improve the working life of rubber seal, dust cover arranges lubrication system, carbon seal ring or oil groove also can directly can be set for lubricating cup, stem surface is made to become the smooth wearing and tearing reduced rubber seal, but do not destroy sealing, extend the working life of rubber seal; And dust ring is set inside dust cover, prevents entering of dust from reaching with this object protecting valve rod with this; What lower guide sleeve adopted is self-lubricating high temp resisting alloy sheath, and it be common high-temperature alloy cover, arranges lubrication module at alloy sheath inwall, can be graphite also can be other oiling agents.
The utility model is achieved by two-stage cooling and changes High Temperature High Pressure sealing into normal temperature sealing, the sealing effect that High Temperature High Pressure sealing lower seal material instability of avoiding knowing clearly causes is not good, cause the phenomenon that maintenance difficult cost is high, the High Temperature High Pressure blowing valve life-span is made to improve more than three times, maintenance period extends more than three times, is worth application and promotes.
