Abstract

Disclosed is a novel energy-saving hydrophobic valve. A valve seat, a fixing hook and a plug are mounted on a valve cover, and a connecting member, a bucket and the fixing hook are connected in a combined manner to be mounted together with a sealing ring and a bushing on a valve body. When condensed water and steam enter the valve body, the bucket moves up and down, so that discharging of the condensed water is realized and steam leakage is effectively prevented. The novel energy-saving hydrophobic valve can be used on steam heat-supply equipment and a steam pipeline to realize discharging of the condensed water and effectively prevent steam leakage, and is long in service life.

Description

A kind of novel energy-conserving drain valve

[technical field]

It is for steam heating equipment and steam line that the utility model relates to a kind of Automatic steam trap Trap, can automatically get rid of steam and use equipment and ducted condensed water, air and other incoagulable gas, and can prevent the automatic valve of steam leakage.

[background technique]

The quality of Automatic steam trap Trap performance, for the normal operation of vapour system, the raising of the gas utilization unit thermal efficiency and the aspects such as reasonable utilization of the energy have crucial effects.But stuck and choking phenomenon takes place in present most of drain valve easily, and working life is shorter, and leakage rate is bigger, causes energy loss, reduces economic benefit.

[model utility content]

In order to overcome the stuck of existing drain valve, choking phenomenon and leakage problem, the utility model provide a kind of novel inverted bucket drain valve, and this valve almost can be all gas utilization units and provides effectively hydrophobic.

The technological scheme that its technical problem that solves the utility model adopts is: a kind of energy-conservation drain valve, it is installed on the valve gap by valve seat, stay hook, plug, with link, after well-bucket and stay hook are connected, together is contained on the valve body with seal ring, lining.When condensed water and steam entered valve body, well-bucket moved up and down, and realized the discharging of condensed water, effectively prevented steam leakage simultaneously.

(1) valve event is realized by a simple lever system, does not have fixed support and complicated being connected, and can not take place stuck and obstruction.

(2) sealing surface adopts spherical sealing, and sealing surface is through special abrasive machining, and service time is more long, and sealability is more good.

(3) flap and valve seat all are arranged on the top of drain valve, and can form the self-cleaning current in the valve, and no dirt blocks puzzlement.

(4) the well-bucket material is stainless steel, and is inverted, and effectively prevents water attack, life-saving.

The beneficial effects of the utility model are: this device can be used on steam heating equipment and the steam line, realizes the discharging of condensed water, and effectively prevents steam leakage, long service life.

Further understand feature of the present utility model and technology contents for making, see the utility model drawings and embodiments for details, yet appended graphic only for reference and explanation usefulness is limited the utility model.

[description of drawings]

Fig. 1 is the utility model schematic representation;

Among the figure 1: lining; 2: plug; 3: valve seat; 4: valve gap; 5: seal ring; 6 stay hooks; 7: spool; 8: link; 9: well-bucket; 10: valve body; 11: filter screen.

[embodiment]

Below in conjunction with drawings and Examples the utility model is described further:

In Fig. 1, a kind of energy-conservation drain valve, working procedure: when device just starts, air and low-temperature condensate in the pipeline enter in the drain valve, well-bucket (9) is by the own wt tenesmus, and link (8) drives spool (7) Open valve, and air and low-temperature condensate are discharged rapidly.In steam entered well-bucket (9), the steam of well-bucket produced to buoyancy, and well-bucket (9) rising link (8) drives spool (7) throttle down.Well-bucket has an aperture on (9), when a part of steam is discharged from aperture, another partly steam produce water of condensation, well-bucket (9) loss of buoyance, to sinking, well-bucket link (8) drives spool (7) Open valve by own wt, periodic duty is interrupted draining.

This device can be used on steam heating equipment and the steam line, realizes the discharging of condensed water, and effectively prevents steam leakage, long service life.

Yet the preferable feasible embodiment of above-mentioned only the utility model, non-so limitation the utility model protection domain is done various distortion or is applied mechanically all within this technological scheme protection domain according to above-described embodiment.

Claims

1. an energy-conservation drain valve is characterized in that, is installed on the valve gap by valve seat, stay hook, plug, with link, after well-bucket and stay hook are connected, together is contained on the valve body with seal ring, lining.
