Abstract
The present invention belongs to the field of machining and nanotechnology, which comprises a valve body, a valve cover and a free semi-floating ball, wherein the valve seat is arranged on the valve cover and is characterized in that the surface of the valve seat is provided with a nanometer carbon pipe coating. Apart from the advantages of a general drain valve, the mechanical nanometer steam drain valve has the advantages that because the surface of the valve seat is made of nanometer materials, the fit position of the semi-floating ball and the surface of the valve seat is difficult to wear and tear, the service life of the present invention is prolonged by over 50 times, and besides, the steam leakage phenomenon caused by the general drain valve can not occur.
Description
[technical field]
The invention belongs to mechanical deep processing and field of nanometer technology.
[background technique]
The claimant once with regard to Automatic steam trap Trap application cross multinomial patent, its mechanical structure mainly is made of valve body, valve gap and half ball float, be provided with admission passage and discharge channel in the valve body, be provided with pad in body cavity, launch tube is housed on the pad, launch tube communicates with admission passage through filter screen, discharge channel communicates with body cavity through valve seat, valve seat is contained on the valve gap, and half ball float is enclosed within on the launch tube, lives mutually between the two and joins.The bottom of half ball float can contact with pad.This Automatic steam trap Trap because of simple in structure, performance is more stable, and be widely used in steam heating equipment and the steam pipe system.But often clash into because understand its structures shape half ball float and valve seat anastomosis, so valve base surface very easily weares and teares, and cause leakage vapour, and have a strong impact on the working life of this valve.
[summary of the invention]
The object of the invention is to combine with nanometer technology, provides a kind of valve base surface to make nanometer material, thereby prolongs the drain valve of its long service life.
Described mechanical nano steam trap, its mechanical structure and prior art are basic identical, do not repeat them here.It is characterized in that valve base surface, particularly be provided with CNT coating with half ball float anastomosis.
Described mechanical nano steam trap is characterized in that CNT coating adopts the mode of chemical plating or plating to be coated with.
Described mechanical nano steam trap is characterized in that containing the elemental phosphorous of CNT 20-30% in said its plating bath of CNT coating.
This mechanical nano steam trap, except that the advantage with general drain valve, owing to adopted nanometer material at valve base surface, valve base surface and half ball float anastomosis are not easy to wear, prolong more than 50 times its working life, and the gas leak phenomenon that general drain valve very easily causes can not take place.
Description of drawings and embodiment
Fig. 1 is a structural representation of the present invention.
Comprise valve body 7, valve gap 1 and free semi-float 2, be provided with admission passage 6 and discharge channel 5 in the valve body 7, on the pad 9 that valve body 7 inner chambers are provided with launch tube 3 is housed, launch tube 3 communicates with admission passage 6 through filter screen 8, discharge channel 5 communicates with valve body 7 inner chambers through valve seat 4, valve seat 4 is contained on the valve gap 1, these valve seat 4 surfaces have CNT coating, described CNT coating adopts chemical plating or electric plating method to be coated with, for making coating reach firm designing requirement, in its plating bath, add and contain the elemental phosphorous of CNT 20-30%.Free half ball float 2 is enclosed within on the launch tube 3, lives mutually between the two and joins.The bottom of free half ball float 2 can contact with pad 9.During use, free half ball float 2 sinks on pad 9, and water of condensation through admission passage 6, overanxious net 8, launch tube 3, flows into valve body 7 inner chambers from launch tube 3 apertures 10 under the inlet outlet pressure differential effect, discharge from valve seat 4, discharge channel 5 then.When freedom half ball float 2 upwards floats under vapor action, and coincide with valve seat 4, then this valve is in resistance vapour state.When water of condensation once more during freedom of entry half ball float 2, a part of vapor condenses Cheng Shui in free half ball float 2, thus free half ball float 2 is sunk, make water of condensation can discharge from valve seat 4 again, go round and begin again thus, reach the effect of resistance vapour, draining.
