The utility model has the advantages of small volume, light weight, convenient opening and closure, and is suitable for using in high, moderate and low pressure of steam.

Description

A kind of float bowl-type Automatic steam trap Trap

Technical field

The utility model relates to drain valve, is specially a kind of float bowl-type Automatic steam trap Trap.

Background technique

Automatic steam trap Trap is the essential valve of steam-heating apparatus or steam pipe system, it can automatically drain the condensed water of continuous generation, and stoping steam to be discharged with water, it is widely used in industries such as weaving, printing and dyeing, rubber, oil, chemical industry, papermaking, beer, electric power.At present, CS43 type Open bucket steam trap commonly used is made by cast iron materials, only is suitable for 10kg/mm ²Following pressure uses, and establishes keg float in its valve body, adopts single valve point sealing configuration, valve seat separates the back draining with the valve point, adds two counterweight bucket pads, and its deficiency is: volume is big, water displacement is little, is frozen easily when winter such as pipeline have fault to break off the base, and working life is shorter; When vapor pressure was middle and high pressure, the first valve point was malfunctioning, and valve seat can't separate with the valve point, causes obstacle to drainage; In addition, comprise float-ball type at the CS41 of water displacement type drain valve, fall hanging bucket type and half float-ball type etc., exist the valve bad sealing to cause steam leakage, do not reach the effect of choke draining, problem such as energy-saving efficiency is low.

The model utility content

Problems such as the volume that exists in the conventional art is big, water displacement is little in order to solve, bad sealing, obstacle to drainage, the utility model provides a kind of volume little, and is in light weight, opens sealing conveniently, is suitable for the float bowl-type Automatic steam trap Trap that uses under the high, medium and low voltage steam.

The technical solution of the utility model is:

A kind of float bowl-type Automatic steam trap Trap, comprise valve body, valve gap, with be provided with keg float in the valve body chamber that the valve gap water inlet communicates, regulating valve shaft one end is fixed at the bottom of the keg float, the other end is connected with the first valve point, described first valve point top is covered with the second valve point, the longitudinal opening pin of offering relatively on the second valve point is movable with horizontal axis on the first valve point and cooperates, the second valve pointed tip matches with the valve gap water inlet, perforate in the middle of it, the perforate two ends are corresponding with the first valve point with the valve gap water inlet respectively, establish source-sensing piece between described valve body chamber and the valve cover cavity, described source-sensing piece is by the source-sensing piece valve gap, source-sensing piece valve seat, and source-sensing piece valve gap, the dress valve block constitutes in the chamber that the source-sensing piece valve seat is connected to form, described source-sensing piece valve seat has the groove of turning one's coat that communicates with valve cover cavity, and has the inlet hole that communicates with the valve body chamber.

Described valve body is provided with exhaust port near entrance point.

Described drain valve is welding or cast structure.

The described second valve pointed tip is frustoconic shape.

The beneficial effects of the utility model are:

1. volume is little, discharge capacity is big, and open and close is convenient.In the utility model valve body keg float is installed, source-sensing piece, first valve point top is covered with the second valve point with its flexible connection, the second valve pointed tip matches with the valve gap water inlet, the valve gap water inlet can be stopped up, have aperture in the middle of it, the perforate two ends are corresponding with the first valve point with the valve gap water inlet respectively, the first valve point can stop up the perforate on the second valve point, because opening diameter is less than the valve gap water inlet diameter in traditional single valve point structure on the second valve point, then to the suction of the first valve point suction less than traditional single valve point structure, pressure release effect by source-sensing piece, in, still open and close is convenient for the first valve point under the high pressure steam, no obstacle to drainage, valve gap water inlet diameter can be greater than traditional single valve point structure simultaneously, the second valve point is opened under the pulling of the first valve point, form big flow draining, solved in, the problem that the valve point can't be opened under the high pressure steam, compare with the mechanical steam drain valve of the same row water yield, volume is little, economize with material, compare with the mechanical steam drain valve of equal volume, the water of condensation discharge capacity is big.

2. the sealing of the utility model valve is tight, can prevent steam leakage, thereby reach the effect of choke draining, the energy-saving efficiency height.
