Abstract
The utility model relates to a flap valve, which is used for controlling a valve to be opened and closed through the rotation of a valve plate and is used for solving the problem that the structure of a high temperature valve on a tertiary air pipe is complicated. The utility model comprises a housing, a valve plate, a rotating shaft and a power mechanism driving the rotating shaft to rotate, wherein the rotating shaft penetrates through the upper part of the housing, the rotating shaft in the housing is connected with the upper end of the valve plate and the shape of the valve plate is the same as the cross section in the housing or is slightly smaller than the cross section in the housing. When the valve plate is in a position perpendicular to the shaft line of the housing, the valve plate blocks on the cross section in the housing and the flap valve lies in a close state. When the valve plate is in a position parallel to the shaft line of the housing, the flap valve lies in an open state, and at this time, the valve plate is at the upper part of the housing and conceals at the outer part of an airflow passage and resistant force of a valve can be reduced. The utility model has the advantages of simple structure and reliable motion.
Description
Technical field
The utility model relates to a kind of gas valve, specifically, is the Flap valve that a kind of rotation by valve plate comes control valve to open, close.It can be applicable on the tertiary-air pipe or other large-scale airduct in the manufacture of cement.
Background technique
In cement industry is produced, be used for High temperature valve on the tertiary-air pipe and be important a kind of of the valve in cement plant.High temperature valve in the past generally adopts the form of gate valve, complex structure, and weight is big, and the installing space of requirement is very big, inconvenient operation, stuck phenomenon easily takes place in valve plate distortion back.Simultaneously, the power of motor is bigger.
Summary of the invention
The utility model mainly solves is the baroque problem of High temperature valve on the tertiary-air pipe, and a kind of High temperature valve of simple in structure, reliable in action is provided.
Flap valve described in the utility model, comprise the power mechanism that housing, valve plate, rotating shaft, drive rotating shaft are rotated, rotating shaft is passed from the top of housing, is connecting the upper end of valve plate in the rotating shaft in housing, and the interior cross section of valve plate profile and housing is identical or be slightly less than the interior cross section of housing.When valve plate perpendicular to the position of housing axis the time, valve plate keeps off on the interior cross section of housing, this Flap valve is in closed condition; When valve plate when being parallel to the position of housing axis, this Flap valve is in opening state, this moment valve plate on the top of housing, be hidden in outside the air-flow path, can reduce the valve resistance.
For above-mentioned Flap valve, can between the two ends of rotating shaft and housing outer wall, be provided with spring.
For above-mentioned Flap valve, can rotating shaft be provided with weight linear meter, weight linear meter is provided with mass; Mass and valve plate are in the both sides of shaft axis.Can reduce the moment of torsion that makes that rotating shaft is rotated like this, reduce the power of power mechanism.
For above-mentioned Flap valve, the top of the interior cross section of this housing is rectangle, the bottom semicircular in shape.
The beneficial effects of the utility model: make the structure of valve simplify greatly, the weight of valve and the power consumpiton of valve all have only about 1/3 of high temperature cut-off valve, and the reliability of valve also is improved simultaneously.When deforming, valve plate stuck phenomenon can not take place yet.Under idle condition, a people can rotate valve plate like a cork.
Reduce the power mechanism power of valve simultaneously, alleviate valve weight.When the size of valve was very big, this advantage was more obvious.
Description of drawings
Fig. 1 is a schematic representation of the present utility model;
Fig. 2 is the right elevation of Fig. 1;
Fig. 3 is the partial enlarged drawing among Fig. 1.
Embodiment
Flap valve shown in Fig. 1,2,3 comprises housing 1, valve plate 7, rotating shaft 3, rotating shaft 5, drives the power mechanism 6 that rotating shaft 5 is rotated.
The internal surface of housing 1 is coated with thermal-protective coating 8.The top 8-1 of the interior cross section of thermal-protective coating 8 is rectangle, bottom 8-1 semicircular in shape.Valve plate 7 profiles are slightly less than the interior cross section of thermal-protective coating 8, to prevent valve plate 7 because thermal expansion and stuck.Rotating shaft 3, rotating shaft 5 are passed from the left and right sides, top of housing 1 respectively, and are supported on respectively on the bearing 11,9 that is fixed on the housing.The upper end of valve plate 7 is connected in rotating shaft 3, the rotating shaft 5 by key 4, locating pin 12 respectively.
When power mechanism 6 by rotating shaft 5 drive valve plates 7 turn to valve plate 7 perpendicular to or when being basically perpendicular to housing 1 axis, valve plate keeps off on the interior cross section of thermal-protective coating 8, this Flap valve is in closed condition; Turn to valve plate 7 when being parallel to the housing axis when power mechanism 6 drives valve plates 7 by rotating shaft 5, this Flap valve is in opening state, this moment valve plate 7 on the top of housing, be hidden in outside the air-flow path, can reduce the valve resistance.
The baffle ring 13 that position-adjustable is arranged in rotating shaft 3 is provided with stage clip 10 between the outer wall of baffle ring 13 and housing 1.The baffle ring that position-adjustable is also arranged in rotating shaft 5 also is provided with stage clip 15 between the outer wall of this baffle ring and housing.When valve plate 7 is moved to the left and when departing from the central position of housing 1 at the axis along rotating shaft 3, the elastic force of stage clip 15 diminishes, 10 elastic force becomes big, makes valve plate 7 move right along the axis of rotating shaft 3 again.When valve plate 7 moves right and when departing from the central position of housing 1, the elastic force of stage clip 15 becomes, and elastic force big, 10 diminish at the axis along rotating shaft 5, make valve plate 7 be moved to the left again along the axis of rotating shaft 5.Therefore this structure can make valve plate be in the center of housing, does not hinder the thermal expansion of valve plate simultaneously again.
Be provided with weight linear meter 2 in rotating shaft 3,5, weight linear meter 2 is provided with mass 14; Mass 14 and the both sides of valve plate 7 at shaft axis.Can reduce the moment of torsion that makes that rotating shaft is rotated like this, reduce the power of power mechanism 6.
The two ends of housing 1 connect pipe respectively, and welded flange on pipe connects with other pipeline with convenient.
Be provided with the inspection door 16 that removably connects with 1 one-tenth of housing on the top of housing 1, when unloading inspection door 16, can check valve plate 7 easily, also valve plate can be shifted out housing together with rotating shaft simultaneously.
