Abstract
The utility model discloses a special ball valve of a melamine process system, which comprises a valve body, wherein a valve core is arranged in the valve body and is connected with a valve stem; an inner thermal insulation cavity is arranged between the valve core and the valve body, and a first thermal insulation air pipe is arranged on the valve body; one end of the first thermal insulation air pipe is communicated with an inner thermal insulation cavity, and the other end thereof is connected with a high temperature air source; a thermal insulation shell is arranged at the outer side of the valve body, and an outer thermal insulation cavity is formed between the outer wall of the valve body and the thermal insulation shell; a second thermal insulation air pipe is arranged on the thermal insulation shell, and one end of the second thermal insulation air pipe is communicated with the outer thermal insulation cavity; the other end of the second thermal insulation air pipe is connected with the high temperature air source, and a purge air hole is arranged in a pipe orifice at one end of the valve body and is connected with one end of a purge pipeline; and the other end of the purge pipeline is connected with the high temperature air source. The utility model has the advantages that: the structural deign is reasonable, the crystallization of process gas at the valve can be effectively prevented so as to ensure the normal work of the valve, the number of downtime maintenance when equipment works can be reduced, the production efficiency is improved, the maintenance cost is reduced, and the like.
Description
Technical field
The utility model relates to a kind of valve, specifically a kind of melamine processes system-specific ball valve.
Background technique
In the melamine preparation process, process gas can make valve normally open or to close easily in the crystallization of valve place when serious, causes the equipment paralysis, influence manufacturing schedule, and the cost of plant maintenance is higher.
Summary of the invention
The purpose of this utility model provides a kind of melamine processes system-specific ball valve, and it can prevent effectively that process gas from the crystallization of valve place, guaranteeing the valve proper functioning.
The utility model for achieving the above object, be achieved through the following technical solutions: comprise valve body, spool is installed in the valve body, connect valve rod on the spool, be provided with interior incubation cavity between spool and the valve body, valve body is provided with the first insulation tracheae, and the first insulation tracheae, one end communicates with interior incubation cavity, and the first insulation tracheae the other end is connected with the high temperature source of the gas.The valve body outside is provided with heat-preservating shell, constitutes outer incubation cavity between valve outer wall and the heat-preservating shell, and heat-preservating shell is provided with the second insulation tracheae, and the second insulation tracheae, one end communicates with outer incubation cavity, and the second insulation tracheae the other end is connected with the high temperature source of the gas.Be provided with the purging pore in the pore of valve body one end, purge pore and be connected with an end that purges pipeline, the other end that purges pipeline is connected with the high temperature source of the gas.
Advantage of the present utility model is: reasonable in design, and it can prevent effectively that process gas from the crystallization of valve place, guaranteeing the valve proper functioning, shuts down the number of times of safeguarding when having reduced equipment work, has improved manufacturing efficiency, has reduced maintenance cost; Heating back holding time is long etc.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
A kind of melamine processes system-specific ball valve described in the utility model comprises valve body 1, spool 2 is installed in the valve body 1, connect valve rod 10 on the spool 2, incubation cavity 3 in being provided with between spool 2 and the valve body 1, valve body 1 is provided with the first insulation tracheae 4, the first insulation tracheae, 4 one ends communicate with interior incubation cavity 3, and the first insulation tracheae, 4 the other ends are connected with high temperature source of the gas 12.During use; high temperature source of the gas 12 is by feeding high-temperature gas in the first insulation tracheae, the 4 inside incubation cavities 3; spool 2 is heated; prevent that spool 2 temperature from crossing low and make process gas in spool 2 places crystallization; guarantee the valve proper functioning; shut down the number of times of safeguarding when reducing equipment work, enhance productivity, reduce maintenance cost.The open and close of valve drive valve rod 10 by controller 11 and finish.The utility model is except can be used in the melamine preparing apparatus, also applicable to the preparing apparatus of various easy crystallization gases.
The utility model is in order to prolong the holding time of spool 2, can be at valve body 1 arranged outside heat-preservating shell 5, constitute outer incubation cavity 6 between valve body 1 outer wall and the heat-preservating shell 5, heat-preservating shell 5 is provided with the second insulation tracheae 7, the second insulation tracheae, 7 one ends communicate with outer incubation cavity 6, and the second insulation tracheae, 7 the other ends are connected with high temperature source of the gas 12.After spool 2 was heated, high temperature source of the gas 12 raise the temperature of valve body 1 by feeding high-temperature gas in the second insulation tracheae, the 7 outside incubation cavities 6, has reduced the radiating effect of valve body 1 inside, the holding time that helps prolonging spool 2.
The utility model can be provided with in the pore of valve body 1 one ends and purge pore 8 in order to prevent the sealing vice division chief crystallization of process gas at spool 2, purges pore 8 and is connected with an end that purges pipeline 9, and the other end that purges pipeline 9 is connected with high temperature source of the gas 12.High temperature source of the gas 12 feeds hot gas along purging pipeline, from purging pore 8 ejections, form air curtain, improves the temperature of sealing vice division chief, prevents the sealing vice division chief crystallization of process gas at spool 2.
