Abstract
The utility model relates to a self air exhaust and water stopping valve used for a heating device, which is composed of air exhaust holes, a valve cap, a sealing pad, an inner cap, a floating bucket, a valve body, and air inlet holes. The utility model has the effects that when air appears in a heating system, a control valve can be automatically opened, the air can be exhausted, the water can not leak, when the air is exhausted, and the air exhaust holes can be automatically closes.
Description
The utility model belongs to the heating system gas exhausting valve, particularly a kind of automatic vent sealing control valve of heating arrangement.
At present, the gas exhausting valve that is installed in heating arrangement is made up of valve and spool, when heating system retains gas, needs staff to turn spool to gas and discharges from the valve exhaust port.This way one is to cause seepy question, the 2nd, and the waste heat supply energy threatens the normal operation of boiler when serious.Bring unnecessary loss for heat supply unit.
It is a kind of when gas occurring in the heating system that the purpose of this utility model is to provide, and this valve can be opened automatically, discharges gas, after gas is discharged, and the automatic vent sealing control valve of the heating arrangement that exhaust port is closed automatically.
The technical solution of the utility model is achieved in that it has exhaust port (1), valve gap (2), sealing gasket (3), inner cap (4), keg float (5), valve body (6), inlet hole (7) is formed, be shaped on the circular cone of band exhaust port (1) in the valve gap, inner cap (4) top is shaped on and the corresponding tongue in circular cone position, sealing gasket (3) is packed in the groove, be shaped on equally distributed projection on the cylinder of keg float (5), inner cap (4) covers on keg float (5), valve body inner bore is shaped on circular cone in the bottom, sidepiece is shaped on the spool of bringing pore into, and keg float packed in the valve body inner bore, valve gap and valve body are connected and composed an overall structure.Material can adopt the high-strength nylon plastics.
The utlity model has simple in structurely, be convenient to install practical advantage.And through 5 kilograms of hydrostatic tests, 12 kilograms of destructive hydrostatic tests, 90 ℃ of heat resistance tests can reach indeformable, and intensity is constant, and discharges gas and watertight ideal effect.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is a structural drawing of the present utility model.
Among the figure: 1 exhaust port, 2 valve gaps, 3 sealing gaskets, 4 inner caps, 5 keg floats, 6 valve bodies, 7 inlet holes.
At first sealing gasket (4) is packed into valve gap in be shaped on the band exhaust port (1) the corresponding inner cap tongue in circular cone position in, be shaped on the cylinder of keg float (5) with inner cap (4) external diameter and equate, with valve body (6) internal diameter be the equally distributed projection of sliding fit, inner cap (4) is covered on keg float (5), for light keg float rises, valve body (6) endoporus bottom is shaped on circular cone, be shaped on to match at sidepiece and bring the spool of pore (7) into former heating arrangement valve hole, keg float is packed on valve body (6) the female cone platform, and can in valve body inner bore, move by easy on and off, the interior threaded hole of valve gap (2) connects formation one overall structure with the base outside thread, can be installed on the valve of former heating arrangement, replace existing manual exhaust valve.Its working principle is: when in the heating system during no gas, keg float (5) is by buoyancy of water work, this moment the buoyancy maximum, rubber gasket (3) line contact sealing that keg float (5) floats to valve gap (2) circular cone upper air-vent tip and inner cap (4) boss is lived exhaust port and water-tight state, when gas in the valve increases gradually, the water surface in the valve body (6) also descends thereupon gradually, cause the keg float bottom surface to contact, come this moment the gas in the autothermal operation system to discharge along being stitched between the projection on the hollow barrel cylinder in the exhaust port (1) with boss in the valve body.Can reach the effect of automatic vent sealing.
Claims (2)
1. the automatic vent sealing control valve of a heating arrangement, it is characterized in that: it has exhaust port (1), valve gap (2), sealing gasket (3), inner cap (4), keg float (5), valve body (6), inlet hole (7) is formed, be shaped on the circular cone of band exhaust port (1) in the valve gap, inner cap (4) top is shaped on and the corresponding tongue in circular cone position, sealing gasket (3) is packed in the groove, be shaped on equally distributed projection on the cylinder of keg float (5), inner cap (4) covers on keg float (5), valve body inner bore is shaped on circular cone in the middle of the bottom, sidepiece is shaped on the spool of bringing pore into, and keg float packed in the valve body inner bore, valve gap and valve body are connected and composed an overall structure.
2. automatic vent sealing control valve according to claim 1 is characterized in that: control valve can adopt the high-strength nylon plastics to make.
