CN205938496U - Novel automatic condensate trap of close heater of axle - Google Patents

Abstract

The utility model discloses a novel automatic condensate trap of close heater of axle, including floater, disk seat, be equipped with drainage channel on the disk seat, is the horizontal inclination of sealed face of disk seat 30 90, is drainage channel 6 8mm. The utility model discloses a horizontal inclination of sealed face increase with the disk seat to make moving down of floater, under same condensate water volume, buoyancy is bigger, increases drainage channel's aperture moreover, reduces the negative pressure, increases the flow of condensate water, and lyophobic effect is better.

Description

Novel shaft close heater automatic steam trap

Technical field

This utility model is related to boiler technology field and in particular to a kind of Novel shaft close heater condensate device.

Background technology

The close heater of axle operationally, can produce substantial amounts of vapor, for making full use of the energy, typically can be by vapor collection Get up and carry out other work.In the transfer pipeline of steam, it generally is configured with drain valve, in order to be automatically drained out condensate, air And other incondensable gas, and effectively stop vapour leakage.In prior art, conventional drain valve is Free Float Type Steam Trap, its Structure is simple, but because seat design is in a side bottom of ball float, the sphere of ball float is little with the sealing surface horizontal tilt angle of valve seat, Ball float buoyancy is not enough or valve seat intake tunnel aperture is little, negative pressure big in the case of, hydrophobic effect is not good.

Content of the invention

The deficiency existing for above-mentioned prior art, the purpose of this utility model is that provide can a kind of structure be simple, make With the close heater automatic steam trap of the extraordinary Novel shaft of effect.

For achieving the above object, the technical scheme of employing of the present utility model is as follows：Novel shaft close heater automatic hydrophobic Device, including ball float, valve seat, valve seat is provided with drainage channel it is characterised in that the sealing surface horizontal tilt angle of valve seat is 30- 90 °, drainage channel is 6-8mm.

Advantage of the present utility model：Compared to existing technologies, this utility model is by inclining the sealing surface level of valve seat Rake angle increases, so that the moving down of ball float, under same condensation water volume, buoyancy is bigger, and increases drainage channel Aperture, reduces negative pressure, increases the flow of condensate, and hydrophobic effect is more preferable.
