Abstract
A drainage water stop valve for a curtain wall comprises a valve body and a valve core. The valve body is a circular tube opened at both ends. The valve core is an elastic circular ball placed in a tubular cavity of the valve body, wherein the diameter of the elastic circular ball is smaller than the diameter of the tubular cavity of the valve body. A stop bump for stopping the valve core is arranged at the front end of the tubular cavity of the valve body. A sealing ring matched with the valve core is arranged on the rear part of the tubular cavity of the valve body. A gap is arranged on the lower part of the sealing ring. A valve seat is arranged at the rear end of the valve body. The bottom of the drainage water stop valve is embedded into a transverse frame preformed hole of a unit. When storm occurs, the elastic ball forming the valve core moves inward under the effect of a pressure difference and is locked on the sealing ring to prevent heavy rain from entering a rear cavity of the unit. After storm, the ball restores the normal position and a small amount of rainwater in the rear cavity of the unit flows out from the gap at the lower part of the sealing ring so that not only can the watertightness and the airtightness of the curtain wall meet the requirement, but also smooth drainage is guaranteed.
Description
Technical field
The utility model relates to the used valve of building, and particularly a kind of building curtain wall is with draining sealing valve.
Background technique
Type unitized curtain wall is manufactured owing to can in factory, accomplishing to produce, on-the-spot simple installation, and the construction time is short, makes its more and more being applied in the building.Use more sideslip formula cell curtain wall at present, the processing of its plate closure part (seam crossings of four adjacent cells plates) is a curtain wall water tightness and a bubble-tight key link.Because of the horizontal frame of this curtain wall connects through multi-functional lock pin, sealing part does not have " cavity ", needs on lock pin and the horizontal frame that is mated, offer weep hole, and it is anterior to make the rainwater that gets into horizontal frame back cavity flow to horizontal frame along weep hole, discharges then.The shortcoming of this kind drainage pattern is that when running into stormy weather, external pressure aqueous reflux can take place return the phenomenon in the cavity greater than the pressure in the cavity.
The model utility content
The utility model purpose be to the shortcoming that said units curtain wall drainage pattern exists provide a kind of simple in structure, when meeting heavy storm rainwater can not get in a large number the unit back cavity, not only can guarantee water tightness and tightness, but also can guarantee that the unobstructed curtain wall of draining is with draining sealing valve.
For realizing above-mentioned purpose, the curtain wall that the utility model provides comprises valve body and spool with draining sealing valve; Be characterized in that said valve body is the pipe of open at both ends; Said spool is for placing valve body tube chamber, rubber-like ball, and its diameter is less than the valve body lumen diameter; Valve body tube chamber front end has the retaining that stops spool protruding, and there is the seal ring that matches with spool at valve body tube chamber rear portion, and sealing ring bottom is jagged, and valve rear end has valve seat.
When above-mentioned draining sealing valve uses; Valve body bottom is embedded in the mounting hole that the horizontal frame in unit offers in advance; When heavy storm took place, owing to the pressure of external pressure greater than the unit back cavity, the elastic pellet that constitutes spool can inwardly move under differential pressure action; Be stuck on the seal ring of its rear side, stop rainwater to get into the unit back cavity in a large number; After heavy storm was gone over, cavity pressure equated behind external pressure and the unit, and little club travels forward under action of gravity (making the valve body front end during installation a little less than the rear end), set back, and a small amount of rainwater that gets into the unit back cavity then flows out from the indentation, there of seal ring bottom.This draining water stop valve structure is simple, with it water tightness of curtain wall and tightness is met the requirements, and can guarantee that again draining is unobstructed.
Description of drawings
The stereogram that Fig. 1 dissects for the utility model draining sealing valve vertically;
Fig. 2 is the use installation diagram (sectional view) of Fig. 1 draining sealing valve;
Fig. 3 is an A portion enlarged view among Fig. 2.
Among the figure: the 1-valve body, the 2-spool, the 3-retaining is protruding, 4-seal ring, 5-valve seat, the horizontal frame in 6-unit.
Embodiment
In conjunction with Fig. 1; The utility model curtain wall is with draining sealing valve, and its valve body 1 is the uncovered pipe in rear and front end, the rubber-like ball of spool 2 for being processed by plastic cement material; Its diameter is less than the diameter of valve body tube chamber; But place valve body official jargon scroll forward and backward, it is protruding 3 to manufacture four retainings that stop that spherical valve core rolls out at the front end of valve body wall of the lumen, manufactures the seal ring 4 (the seal ring internal diameter is less than valve core diameter) that matches with spool at the rear portion of valve body wall of the lumen; The breach of 10mm is arranged at sealing ring bottom, at valve rear end with the bonding round ring seat 5 of structure glue.
In conjunction with Fig. 2 and Fig. 3, the horizontal frame 6 in the unit of curtain wall is adding man-hour, perforate in advance on horizontal frame, and bore size will be complementary with the size of draining sealing valve.After processing the horizontal frame in unit, sealer is smeared at the place at preformed hole, and the valve body with draining sealing valve embeds in the preformed hole then, makes matching gap reach the optimum state, guarantees the stability and the sealing reliability of draining sealing valve.To carry out draining and sealing performance test to mounted draining sealing valve at last, see through test whether its performance satisfies actual usage requirement, be delivered for use after performance is qualified.
