Abstract
The utility model relates to a valve body of a fire hydrant; a water inlet is arranged below the valve body; a water outlet is arranged in the side surface of the valve body; valve core installation base holes are arranged on the upper part and the lower part of the inner side of the valve body; an inner protruding ring is arranged between the water inlet and the valve core installation base hole at the inner side of the valve body; and the inside diameter B of the inner protruding ring is less than the inside diameter A at the inner side of the water outlet. When the valve body of the fire hydrant is used, the throttling phenomenon at the water outlet is avoided so that water in the inner cavity of the valve body can be discharged in time; the pressure in the inner cavity of the valve body is relatively reduced; higher requirements of a sealing member are not required; and the service life of the fire hydrant is prolonged.
Description
Technical field
The utility model relates to a kind of valve body, particularly a kind of valve body that is used for fire hydrant.
Background technique
Existing fire hydrant is the housing shape with valve body; Water intake is arranged below valve body; There is water outlet the side; Be equipped with spool fitting seat mouth at the inboard upper and lower of valve body, the internal projecting ring of oriented inner bulge between lower valve core fitting seat mouth and water intake, the internal diameter of internal projecting ring is compared greatly with the minimum diameter at water outlet place.During use, high pressure water advances in water intake gets into valve body, is discharged by water outlet again, forms throttling at the water outlet place, remains body cavity and has quite high pressure, the Sealing in it is formed threaten, and leaks easily, has influenced the working life of fire hydrant.
Summary of the invention
Do not have throttling phenomenon, body cavity not to produce high pressure, Sealing is required fire hydrant valve body low, long service life at the water outlet place when purpose of the utility model provides a kind of the use, overcome the deficiency of existing technology.
The valve body of the fire hydrant of the utility model; Water intake is arranged below valve body; Side of valve body has water outlet; The inboard upper and lower of valve body is equipped with spool fitting seat mouth, between water intake and spool fitting seat mouth, is provided with internal projecting ring in the valve body inboard, and the internal diameter B of described internal projecting ring is less than the inboard internal diameter A of water outlet.
The valve body of the fire hydrant of the utility model does not produce the throttling phenomenon at the water outlet place during use, and the water of body cavity can in time be discharged, and body cavity pressure reduces relatively, and Sealing is not had higher requirement yet, has prolonged the working life of fire hydrant.
Description of drawings
Fig. 1 is the utility model embodiment structural representation.
Embodiment
As scheme shown in the institute 1: valve body is the housing shape, and water intake 1 is arranged below valve body, and side of valve body has water outlet 2, and water intake 1 place is that internal thread is used for joining with water system, and the water outlet place is that outside thread is used for joining with shower.The inboard upper and lower of valve body is equipped with spool fitting seat mouth 3, through spool fitting seat mouth 3 spool is installed.The valve body inboard water intake 1 and below spool fitting seat mouth 3 between be provided with to the inside protruding internal projecting ring 4.The internal diameter B of internal projecting ring 4 is less than the internal diameter A of the minimum of water outlet 2 inboards.Do not produce the throttling phenomenon at water outlet 2 places during use, the water of body cavity can in time be discharged, body cavity pressure reduces relatively, and Sealing is not had higher requirement yet, has prolonged the working life of fire hydrant.
Claims (1)
