Abstract
The utility model provides a slidingtype exhaust valve, includes the valve body, the casing, and the valve clack, the valve rod, its characterized in that: have the cavity in the casing, casing one end is semi -circular, the other end along the circumferencial direction with the valve body is connected, the valve body with open the casing junction has the gap, valve clack and valve rod one end fixed connection, and the casing side sets up and valve rod matched with spout, the valve rod drives the valve clack and slides from top to bottom in the spout, the valve body inner wall has the recess with valve clack matched with. Through setting up the recess in valve body and valve clack contact department, during the valve clack stretched into the recess, even when the wind speed when the pipeline in is great, fine sealed effect can be played in the realization control big or small to valve open that the valve clack also cannot be stable in the time of in the valve clack stretches into the recess completely.
Description
Technical field
This utility model is related to valve body technical field and in particular to a kind of exhaust valve.
Background technology
Exhaust valve is widely used in ventilation shaft, and existing air draft valve arrangement is typically all to pass through to set in the duct
Put flap, valve rod is connected with flap and passes through from pipeline section, adjust flap by rotation valve rod real
Existing closedown of pipeline or the control of unlatching and ventilation, this operation principle being similar to that butterfly valve,
Thus when in pipeline wind speed be difficult to the effective control to air quantity when larger, higher for sealing requirements
Pipeline nor meet require.
Utility model content
Technical problem to be solved in the utility model is to overcome existing technological deficiency, provides a kind of cunning
Dynamic formula exhaust valve.
Technical problem to be solved in the utility model to be realized using following technical scheme:
A kind of slidingtype exhaust valve, including valve body, housing, flap, valve rod, has cavity in described housing,
Shell one end is semicircle, and the other end is along the circumferential direction connected with valve body, described valve body and housing junction
Have gap, described flap is fixedly connected with valve rod one end, flap can be along valve body and housing junction
Gap enter housing hollow in, valve interior wall has the groove matching with flap, when exhaust valve is closed,
Flap is in close contact with groove.
The chute that the setting of described housing side matches with valve rod, described valve rod drive flap in chute on
Lower slider.Have circular hole in valve rod at the other end, pole insertion circular hole is interior and can slide in circular hole,
In housing another side, location hole corresponding with pole is set, when pulling pole band ovable valve stem mobile, according to
According to the length needing flap to need to stretch in valve body, pole is inserted in corresponding location hole, so that valve
Flap position is fixed.
The beneficial effects of the utility model are: by arranging groove at valve body with valve flap contacts, flap is stretched
Enter in groove, even if when the wind speed in pipeline is larger, the realization that flap also cannot be stable is to valve
Open the control of size, good sealing effectiveness can be played when flap protrudes fully in groove.
Brief description
Fig. 1 is this utility model schematic diagram；
Fig. 2 is this utility model along a-a face schematic diagram.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that this utility model is realized are easy to bright
White understanding, with reference to being specifically illustrating, is expanded on further this utility model.
As shown in Figure 1, 2, a kind of slidingtype exhaust valve, including valve body 1, housing 2, flap 6, valve rod 5,
There is cavity 9, housing 2 one end is semicircle, the other end is along the circumferential direction connected with valve body 1, valve in housing 2
Body 1 and housing 2 junction have gap, and flap 6 is fixedly connected with valve rod 5 one end, and flap 6 can be along valve
Body 1 enters in housing 2 cavity 9 with the gap of housing 2 junction, and valve body 1 inwall is had and matched with flap 6
Groove 10, when exhaust valve is closed, flap 6 is in close contact with groove 10.
The chute 3 that the setting of housing 2 side is matched with valve rod 5, valve rod 5 drives flap 6 upper and lower in chute 3
Slide.Have circular hole 4 in valve rod 5 at the other end, pole 7 insertion circular hole 4 is interior and can slide in circular hole 4
Dynamic, location hole 8 corresponding with pole 7 is set in housing 2 another side, moves when pulling pole 7 band ovable valve stem 5
When dynamic, according to the length needing flap 6 to need to stretch in valve body 1, pole 7 is inserted corresponding location hole 8
In, so that flap 6 position is fixed.
Of the present utility model ultimate principle and principal character and of the present utility model excellent have been shown and described above
Point.It should be understood by those skilled in the art that, this utility model is not restricted to the described embodiments, above-mentioned
Principle of the present utility model is simply described, without departing from this utility model described in embodiment and description
On the premise of spirit and scope, this utility model also has various changes and modifications, these changes and improvements
Both fall within the range of claimed this utility model.This utility model claims scope by appended power
Sharp claim and its equivalent thereof.
