Abstract

The utility model relates to an vapor-constrained drain valve, which is characterized in that: a water inlet pipe is arranged at the top of a water storage tank, and a water outlet pipe is arranged at the bottom of the water storage tank; a floating ball provided with a horizontal bar is hinged on the inner wall of the water storage tank; the bar of the floating ball is connected with a cone plug provided with a sealing gasket to plug up the water outlet pipe. In service of the vapor-constrained drain valve, condensate water and vapor enter into the water storage tank through the water inlet pipe, and the vapor is above the water because the water density is greater than the vapor; the water level in the water storage tank ascends along with the accumulation of the condensate water in the water storage tank, and the floating ball ascends along with the rise of the water level to drive the cone plug to ascend and open the water outlet, then the condensate water is discharged from the water outlet and the water level descends; the floating ball descends along with the fall of the water level to drive the cone plug to descend and close the water outlet. During the entire process, only condensate water is discharged from the heating line and the vapor is constrained in the heating line.

Description

Bundle gas drain valve

Affiliated technical field

The utility model relates to a kind of novel bundle gas drain valve, and this bundle gas drain valve is effectively discharged the condensed water in the caliduct, and with the water vapour bundle in caliduct, thereby reduce the waste of the energy.

Background technique

At present, the mode of central heat supply heating is hot air heating and hot-water heating dual mode.When using hot air heating, water vapour is worked in pipeline and can be generated condensed water after the release heat.For condensed water is discharged from pipeline, traditional method one is that a drain valve is installed on pipeline, the osculum of this drain valve has only the pinprick size, be easy to stop up, the maintenance trouble, and after this drain valve discharges the condensed water in the pipeline, water vapour also discharge conduit can be caused the waste of the energy; The 2nd, be directly installed on the heating pipeline, water, gas are discharged the heating pipeline together, and the energy waste that this method causes is bigger.

Summary of the invention

In order to solve the shortcoming of traditional hot air heating heating pipeline de-water.The utility model provides a kind of bundle gas drain valve, and condensed water in the pipeline of effectively hot air heating being warmed oneself is discharged, and with the water vapour bundle in caliduct, thereby reduce the waste of the energy.

The technological scheme that its technical problem that solves the utility model adopts is: one has individual intake pipe above the water storage box, individual outlet pipe is arranged below.It is sidewards ball float that the water storage box inwall is fixed a bar with hinge, connects the circular cone plug of a band sealing gasket on the ball lever, blocks outlet pipe.During the work of bundle gas drain valve, condensed water, gas enter water storage box from intake pipe, because the density of water is bigger than water vapour, Gu Shui is following, and water vapour is last.Along with condensed water accumulates in water storage box, liquid level rises in the water storage box, ball float rises and rises and drive the circular cone plug and rise along with liquid level, water outlet is opened, condensed water is got rid of from water outlet, then liquid level descends, and ball float descends and drives the circular cone plug along with liquid level decline and descends, and water outlet is closed.Have only condensed water to discharge from heating pipeline in entire work process, water vapour is then restrainted in caliduct, thereby reduces the waste of the energy.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a bundle gas drain valve assembling schematic representation;

Fig. 2 is a bundle gas drain valve water storage box schematic representation;

Fig. 3 is a bundle gas drain valve ball float schematic representation;

Condensed water in the caliduct enters the water storage box (Fig. 1-1) from water intake (Fig. 2-1), along with entering of condensed water, liquid level raises gradually in the water storage box (Fig. 1-1), ball float (Fig. 1-3) raises and raises along with liquid level, and drive circular cone water outlet plug (Fig. 3-1) and separate with sealing gasket (Fig. 1-2), the condensed water in the water storage box flows out from water outlet (Fig. 2-3).Along with the outflow of condensed water, the liquid level in the water storage box descends, and ball float (Fig. 1-3) descends along with the decline of liquid level, and it is identical with sealing gasket (Fig. 1-2) to drive circular cone water outlet plug (Fig. 3-1).Finish a working procedure.

Claims

1. restraint the gas drain valve for one kind, it is characterized in that: one has individual intake pipe above the water storage box, individual outlet pipe is arranged below.It is sidewards ball float that the water storage box inwall is fixed a bar with hinge, connects the circular cone plug of a band sealing gasket on the ball lever, blocks outlet pipe.
