Abstract
The utility model relates to an adjustable boiler backwater automatic valve, composed of a triple valve body, an upper and a lower valve plates, connecting rods of the valve plates, a sealing pad, a sealing ring, a limiting guide pipe, a return spring mechanism, and a current limiting mechanism. Trial shows that the utility model can be opened quickly and closed tightly, has no water impact and is used automatically.
Description
The utility model step and a kind of adjustable boiler blow-down water self-acting valve.
ZL94211757.3 discloses a kind of " boiler blow-down water self-acting valve ", this valve is made up of valve body, last valve plate and end face elastic sealing gasket, lower valve plate and circumferential elastic pad thereof, last lower valve plate connecting rod, spacing guide holder, main line intake-outlet and pilot line intake-outlet, its shortcoming is for the tall building heating system water hammer to be arranged when the valve closing, for the low storied building heating system, the main line valve plate is not closed completely, and the scene can't be regulated according to system.
The purpose of this utility model is to develop does not a kind ofly have water attack, close tight, on-the-spot adjustable boiler blow-down water self-acting valve.
The purpose of this utility model is achieved in that between the pilot line import and export bottom of ZL94211757.3 boiler blow-down water self-acting valve sets up Returnning spring mechanism and water outlet current-limiting mechanism.
Embodiment's accompanying drawings of the present utility model is as follows:
Accompanying drawing is a structural representation of the present utility model.
As shown in the figure, 1 for the person in charge leads suction flange, and 2 is lower valve plate, 3 is elastic sealing gasket, 4 is last lower valve plate connecting rod, and 6 is the guide and limit pipe, and 6 is valve body, 7 is lower valve plate, 8 is the circumferential elastic ring, (as O type ring, Y type ring or disc type elastic sealing gasket), and 9 is Returnning spring, 10 is the Returnning spring compressing tablet, 11 is spring conductor rod, the 12 stray bullet spring compressing tablets that exceed, the 13 stray bullet springs that exceed, 14 is bottom, 15 is outlet(discharge) flange, and 16 is valve seat, 17 tightening nuts, 18 is the Returnning spring adjusting nut, and 19 is the pilot line intake-outlet.
Last lower valve plate 2 and 7 usefulness connecting rods 4 are tightened to one, during plate valve 7 displacements instantly, last valve plate 2 moves thereupon, connecting rod 4 passes guide and limit pipe 5, this pipe is below valve seat 16, be used for the spacing of connecting rod 4 and guiding, lower valve plate 7 is two-part by circumferential elastic pad 8 with the bottom of valve, and a part communicates with valve outlet port, and a part communicates with pilot line import and export 19, between bottom 14 and control valve import and export 19, Returnning spring 9 is housed, compressing tablet 10 and nut 18 constitute controlling mechanism, be used to regulate the tight power of giving that valve plate 2 closes, for the high-rise building heating system, pressure of return water is little, give tight power and turn down, to avoid water hammer; For lower building or one-storey house heating system, pressure of return water water is given tight power and is transferred greatly, and valve plate 4 resets and closes tight on guaranteeing.
By spring conductor rod 11, the current-limiting mechanism that compressing tablet 12 and current limliting spring 13 constitute is used for the control of the control valve turnover water yield.When the turn on pump Open valve, the hydraulic pressure of pilot line is pressed to current limliting spring 13 with compressing tablet 10, makes it quick water inlet, when the termination of pumping throttle down, current limliting spring 13 compresses compressing tablet 10, and water can only flow out from gap location, prolong the delivery time of control water, make valve plate 2 Slow Closes, so that eliminate water hammer.
On probation showing, this valve is opened soon, Guan Deyan, no water attack, full-automatic.
