Description

Guide piston inverted bucket type drain valve

Technical Field

The invention belongs to the technical field of auxiliary equipment of a drain valve, and particularly relates to a guide piston inverted bucket type drain valve.

Background

The inverted bucket type drain valve is characterized in that an inverted bucket is arranged in the inverted bucket type drain valve and is a liquid level sensing element, the opening of the bucket is downward, and the inverted bucket is connected with a lever to drive a valve core to open and close the valve. The inverted bucket type drain valve can exhaust air, is not afraid of water hammer, and has good antifouling performance, an inverted bucket is arranged in the inverted bucket type drain valve and is a liquid level sensing element, the opening of the bucket is downward, and the inverted bucket is connected with a lever to drive a valve core to open and close the valve. The inverted bucket type trap can exhaust air, is not afraid of water hammer, and has good stain resistance. The super-cooling degree is small, the steam leakage rate is less than 3%, the maximum back pressure rate is 75%, the connecting pieces are more, and the sensitivity is not as good as that of the free floating ball type drain valve. Because the inverted bucket type drain valve closes the valve by the upward buoyancy of steam, the inverted bucket type drain valve is not suitable for use when the working pressure difference is less than 0.1 MPA. When the device is just started, air and low-temperature condensed water in the pipeline enter the drain valve, the inverted bucket falls down by the weight of the inverted bucket, the inverted bucket is connected with the lever to drive the valve core to open the valve, and the air and the low-temperature condensed water are quickly discharged. When steam enters the inverted bucket, the steam of the inverted bucket generates upward buoyancy, and the inverted bucket rises to be connected with the lever to drive the valve core to close the valve. The inverted bucket is provided with a small hole, when one part of steam is discharged from the small hole and the other part of steam generates condensed water, the inverted bucket loses buoyancy and sinks downwards by the self weight, and the inverted bucket is connected with a lever to drive a valve core to open a valve, so that the inverted bucket works circularly and discharges water discontinuously.

For example, application No.: the invention discloses a valve core assembly which comprises a valve core and a valve seat, wherein the valve seat is of an annular structure with a large upper part and a small lower part, the upper part of the inner annular surface of the valve seat is a conical sealing surface, and the lower part of the inner annular surface of the valve seat is a circular surface; the valve core is cylindrical and can be in sealing fit with the sealing surface of the valve seat; still include cylindric valve plug, the valve plug sets up in the case bottom and coaxial with the case, the size of valve plug matches with the torus of disk seat.

Based on the search of the above patent and the discovery of the structure in combination with the prior art, when the steam trap similar to the above patent is used, it can be seen from the principle of the steam trap that part of steam is discharged while accumulated water is discharged, and the part of steam is discharged to the air to be diffused, which causes a great deal of waste of water resources.
