Abstract
The utility model relates to a valve body of a boiler liquid level meter for a boiler, which is mainly composed of an upper valve, a lower valve and a meter body. A hole on a valve rod is formed as a passageway when the valve is opened and closed, and a sphere in the valve is formed as a secondary valve. The utility model has the advantages of simple structure, easy operation, flexible on-off, and low cost, being suitable for displaying liquid level in industrial equipment of boilers, chemical engineering, petroleum, etc.
Description
The utility model relates to the valve body on a kind of steam boiler liquid level gauge.
Be used to monitor the liquid level gauge of boiler water level, simple in structure because of it, easy for installation, advantage such as dependable performance and being used widely.Yet the valve body that is loaded on the liquid level gauge two ends is because of complex structure and be in high temperature for a long time, and defective such as switch is dumb below the moist situation is brought many inconvenience to the user.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part and valve body on a kind of boiler liquid level meter is provided.
The utility model is achieved by the following scheme: the passage when utilizing hole on the valve rod to constitute the switching of valve, the spheroid in the valve body constitutes the secondary valve, thereby realizes the purpose of this utility model.
The utlity model has simple in structure, processing ease, switch is flexible, low cost and other advantages is suitable for the use that commercial units such as boiler, chemical industry, oil show liquid level positions.
Below in conjunction with accompanying drawing the utility model is further specified:
Accompanying drawing 1 is the utility model outside drawing;
Accompanying drawing 2 is upper valve body (a 6) cut-open view;
Accompanying drawing 3 is following valve body (2) cut-open view.
See accompanying drawing 1,2,3, the utility model is mainly by following valve body (2), upper valve body (6), table main body (5) is formed, upper valve body (6) is by upper valve rod (7), upper valve body shell (8), last valve seal cover (9), spheroid (10) is formed, upper valve body shell (8) is the threeway shape, and upper valve rod (7) axially has blind hole, and in blind hole one hole is arranged radially, upper valve rod (7) one ends pass upper valve body shell (8), and be fixed with handle (12), between upper valve body shell (8) and upper valve rod (7), be lined with valve seal cover (9), last valve seal cover (9) has a hole with upper valve rod (7) the radial hole place of matching, and in the connection place of upper valve body shell (8) and steam inlet pipe (11) spheroid (10) is arranged; Following valve body (2) is by descending valve shell (1), lower valve rod (3), following valve seal cover (4), spheroid (10) composition.Following valve shell (1) is the four-way shape, lower valve rod (3) one ends axially have blind hole, through hole radially being arranged and one hole is arranged in blind hole in its vertical direction, lower valve rod (3) one ends pass down valve shell (1), and be fixed with handle (12), down between valve shell (1) and the lower valve rod (3), be lined with down valve seal cover (4), following valve seal cover (4) has orthogonal two through hole with lower valve rod (3) the radial hole place of matching, and in the connection place of following valve shell (1) and water inlet pipe (13) spheroid (10) is arranged.
When using the utility model, on, following valve body (6), (2) by last, following cross over pipe (14) links to each other with table main body (5), when pulling handle (12), vapour, water is respectively by last, lower valve rod (7), (3) enter, following valve body (6), (2) in, when both are when opening shape, vapour, water is communicated with exterior line through table main body (5), when his-and-hers watches main body (5) when cleaning, to descend the handle (12) on the valve body (6) to rotate 90 °, following valve body (6) is by shape with exterior line, only links to each other with table main body (5), but the pipeline in the his-and-hers watches main body (5) cleans, at this moment, the handle (12) on the upper valve body (6) is pulled 90 °, is by shape; When the glass plate on the table main body (5) breaks suddenly, pressure in the table main body (5) reduces, pressure in valve body (6), (2) is greater than the pressure in the table main body (5) up and down, the blind hole position of spheroid (10) upper and lower valve rod (7), (3) in this moment upper and lower valve body (6), (2) because of pressure differential gets lodged in, form the secondary valve, automatic-closing valve.
