Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, following embodiment should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model.
As shown in Fig. 1 to 5, a kind of thermodynamic drain valve, described drain valve comprises valve body 12, and the top of described valve body 12 is provided with valve seat 3, and described valve body 12 is monolithic construction with valve seat 3; The top of described valve seat 3 is provided with valve gap 1; One end of described valve body 12 inside is provided with import 6, and the other end is provided with outlet 13.The rear end of described import 6 is connected by the top of horizontal transition hole 7 with filter chamber 9, and the bottom of described filter chamber 9 is closed by plug 11, and described filter chamber 9 is for being obliquely installed.Described filter chamber 9 is made up of two cylinders that bore is different, is connected between these two cylinders by one section of centrum; The bore of described filter chamber top cylinder 8 is less than the bore of its underpart cylinder.The inside of described filter chamber 9 is provided with punching filter screen 10; Described punching filter screen 10 for riding hole in one end, Bu Qi hole, one end; Described one end of not riding hole is connected with the top of described filter chamber 9, described in ride hole one end be connected with described plug 11.Ride nose end and can reach the effect that closes up preferably, make filtering effect better.The top columnar part of described filter chamber 9 is fixed in the upper end of described punching filter screen 10, and the lower end of described punching filter screen 10 is withstood by plug 11.
The top of described valve seat 3 is provided with a ring chute 15; The chamber formed between described valve seat 3 and described valve gap 1 is transformation room 16, is provided with valve block 2 in described transformation room 16.Inlet channel 4 and outlet flow 14 is provided with in described valve body 12; The bottom inlet place of described inlet channel 4 is connected with the top of described filter chamber 9, and the top exit place of described inlet channel 4 is communicated with described circulating tanks 15 and transformation room 16; The top inlet place of described outlet flow 14 is communicated with described circulating tanks 15, and the bottom outlet place of described outlet flow 14 is communicated with described outlet 13; Two horn shape runners 5 are extended near one end of valve body 12 inside in described outlet 13; The bottom surface of described horn shape runner 5 is plane of inclination, is parallel relation between described plane of inclination and the filter chamber 9 be obliquely installed.Described outlet flow 14 has three, is arranged at equal intervals in described circulating tanks 15, and arranges around the periphery of described inlet channel 4; Wherein two outlet flow 14 are connected with the horn shape runner 5 described in two respectively.Three outlet flow 14 of above-mentioned equivalent arrangements, can ensure that valve block 2 opens and closes relatively more steady, thus extend the working life of thermodynamic drain valve.In outlet 13, extend two horn shape form runners, three uniform outlet flow 14 can be realized and export 13 and be communicated with; Meanwhile, clear up the simplicity of core when considering again casting, be parallel relation between the bottom surface of described horn shape runner 5 and filter chamber 9, leave larger space as cast cleaning.
Valve body 12 in the present embodiment and valve block 2 all adopt sclerosis chromium type stainless-steel grinding shaping, have corrosion-resistant, wear-resisting, antifreeze advantage, and the long lifetime that can meet under high pressure uses.
The working principle of the present embodiment thermodynamic drain valve is as follows:
When starting to ventilate, air and water of condensation enter import 6, enter filter chamber 9 through horizontal transition hole 7, inlet channel 4 is entered after being filtered by punching filter screen 10, valve block 2 is upwards boosted, enters outlet flow 14 by circulating tanks 15, then discharge condensed water from outlet 13.Then, steam enters drain valve.The speed that the speed flow through below valve block 2 due to steam flows through than water of condensation is much bigger, and according to Bernoulli's therem, the pressure below valve block 2 reduces, and valve block 2 is closed by the pressure above valve block 2, reaches the object of resistance vapour.During valve closing, steam in transformation room 16 dispels the heat to the air of valve gap 1 contact outside, the steam in transformation room 16 is made to be condensed into water of condensation gradually, therefore the pressure in transformation room 16 reduces gradually, and when the pressure in transformation room 16 reduces to a certain extent, valve block 2 is lifted again, then valve opening, the water of condensation accumulating in drain valve inlet after valve closing discharged from outlet 13, so far, drain valve can work again and again.In summary, the working principle of gravity to this kind of thermodynamic drain valve is had no effect, and therefore its mounting point can be level, inclination, any form such as vertical.
Thermodynamic drain valve described in above-described embodiment is typically applied in the hydrophobic of main steam header line and arm, heat traced pipeline and small flow equipment, be widely used in iron and steel, chemical industry, automobile, pharmacy, food and drink, papermaking and other use steam-heated industrial field.
The above embodiments are only be described preferred implementation of the present utility model, not limit design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept, the various modification that related domain ordinary person makes the technical solution of the utility model and improvement, all should drop into protection domain of the present utility model.
