Abstract
The utility model discloses a kind of cone valve of boiler slag removal, the cone valve arranges pulley guiding mechanism (2) so that switch frictional resistance reduces, it is to avoid cone valve occurs bite in switching process.Observation window device (3) is set, by slag inlet situation inside observation port cone valve, valve pocket (6) is fixed on valve body (8), ensure the alignment degree of valve rod (5) valve element (7) and valve pocket (6) during assembling, fixing valve pocket (6) when avoiding installation causes alignment degree poor, sealing clearing apparatus (4) is set up on valve body (8), when slag notch gas producer slag is piled up, can be purged by sealing clearing apparatus (4) with compressed air, dispel accumulation slag so that slag tap smooth.
Description
Technical field
This utility model is related to boiler slag draining technology field, and in particular to a kind of boiler slag removal cone valve.
Background technology
Current thermal power generation accounting is more than 70%, and the discharge of power plant boiler slag has to the stable operation of boiler
Vital impact.The ash temperature that boiler is discharged is higher, and typically at 800～900 DEG C, so red-hot lime-ash not only deteriorates
Field operation condition, requirement to residue extraction mechanism are also higher.When cone valve is used for boiler slag removal, you can control slag emission
Switch, it is also possible to the flow of slag is controlled by the regulation of aperture size, makes the more stable reliability of operation of boiler.Existing
Cone valve in switch-mode regulation easy bite, cause slag-drip opening occur slag accumulation, hinder slag-drip opening slag tap, another valve element valve pocket
Valve pocket is fixed during installation and easily causes that alignment degree is poor, so as to affect the stability of boiler slag removal.
Content of the invention
This utility model provides a kind of cone valve, solves the problems, such as cone valve easy bite in switch-mode regulation, valve element valve
Set alignment degree problem.
The technical scheme adopted by this utility model is cone valve, including valve body and the hollow deslagging positioned at valve inner
Chamber, inclined T-shaped in deslagging chamber, deslagging chamber horizontal direction right part is extended on the outside of valve body, for entering cinder notch, the vertical side in deslagging chamber
To bottom extend to the outside of valve body, be slag notch, the lumenal levels direction in deslagging chamber is provided with valve rod, and valve rod is in deslagging
Intracavity can be moved left and right, and the left side connection YE of valve rod, the right-hand end connection valve element of valve rod, valve element are extended to into slag
Mouthful, valve element overcoat valve pocket, valve pocket are fixed on valve body, and valve body upper end inclines and is provided with observation window device, described observation window device
Deslagging chamber is extended to, valve body upper end is vertically provided with sealing clearing apparatus, and sealing clearing apparatus bottom inclines and extends to into cinder notch.
Described valve rod is provided with pulley guiding mechanism, and described pulley guiding mechanism adopts 2 groups of rolling pulleies to valve rod
It is oriented to.
The beneficial effects of the utility model are：The switch-mode regulation of cone valve is more flexible, can be seen by observation window device
Examine inner case, using sealing clearing apparatus to slag pile up cleared up in time, it is to avoid the blowing out accident that stifled slag is caused send out
Raw.

Specific embodiment
This utility model is described further in conjunction with accompanying drawing 1, operation principle of the present utility model：Slag emission
When, 1 regulating valve stem 5 of YE makes valve element 7 leave valve pocket 6, enters cinder notch and is opened.Slag enters deslagging chamber 9 through entering cinder notch,
It is that slag-drip opening is discharged via the vertical ends in deslagging chamber 9.When stopping discharge, YE 1 is moved with ovable valve stem 5, makes valve element 7
Closely sealed with valve pocket 6, close into cinder notch.The position of the movement of valve element 7, distance are by travel switch control.By controlling valve element 7 and valve pocket
6 sizes that opens carry out the size of working the slag discharge capacity.As shown in figure 1, structure composition of the present utility model：YE 1,
Pulley guiding mechanism 2, valve body 8, valve element 7, valve rod 5, valve pocket 6, observation window device 3, sealing clearing apparatus 4 and deslagging chamber 9.Electricity
Power set of the dynamic executor 1 for valve rod 5, band ovable valve stem 5 are moved left and right in deslagging chamber 9, by moving left and right for valve rod 5,
Open and close into cinder notch, observation window device 3 is arranged on the upper end leftward position of valve body 8, incline and extend in deslagging chamber 9, lean on
The position of nearly valve element 7, is easy to observe the deslagging situation into cinder notch, when there is deslagging accumulation, is carried out using sealing clearing apparatus 4
Purging, seals clearing apparatus 4 and is vertically set on the upper end of valve body 8, position on the right side, and the lower end for sealing clearing apparatus 4 inclines
Extend to into cinder notch, be easy to dispel accumulation slag.The corresponding effect of each structure is as follows：
1st, pulley guiding mechanism 2 is oriented to valve rod 5 using 2 groups of rolling pulleies so that switch frictional resistance reduces, and keeps away
Cone valve is exempted from and bite has occurred in switching process.
2nd, be additionally arranged observation window device 3 on cone valve top, observation window device 3 by the pressure clear glass of high temperature resistant, manually
Valve, steel construction, sealing member composition.Observation port is opened by the pressure clear glass of high temperature resistant and internal insulation, when needing to observe and is seen
The manually-operated gate for examining device can be seen slag inlet situation inside cone valve.
3rd, valve pocket 6 is fixed on valve body 8, ensure the alignment degree of 5 valve element 7 of valve rod and valve pocket 6 during assembling, it is to avoid during installation
Fixed valve pocket 6 causes alignment degree poor.
4th, sealing clearing apparatus 4 is set up on valve body 8, when slag notch gas producer slag is piled up, can be passed through with compressed air
Sealing clearing apparatus 4 is purged, and dispels accumulation slag so that slag tap smooth.
