Abstract
The utility model relates to a filtering drain valve, which mainly resolves the problem of effect on service life of products caused by the fact that the existing drain valve cannot filter steam. A through hole communicated with an air inlet and a nozzle is arranged at the bottom of the valve body, a sleeve column matched with the through hole is arranged in the through hole, a groove is arranged on the end portion of the sleeve column, the air inlet is communicated with an air outlet through the groove, and a filtering screen is arranged at the opening position of the groove. The filtering screen is added to the drain valve, so that double filtering to the steam can be achieved, some impurities in the steam can be effectively filtered, and the fact that internal parts of the drain valve are polluted and affects service life of the products can be avoided.
Description
Technical field
The utility model relates to a kind of valve, refers in particular to the drain valve with filtering function.
Background technique
Drain valve has the function of non-condensible gases such as steam condensate and the air in automatic eliminating heating plant or the steam line, and leak-off steam not, because drain valve has the effect of draining resistance vapour, can make steam-heating apparatus evenly give heat.As be applied to iron, and improve steam quality, owing to lack the steam filtration function in the drain valve, can not effectively filter some impurity, thereby cause the inner member of drain valve to be polluted, influenced the working life of product.
The model utility content
In order to overcome deficiency and the defective in the background technique, the utility model provides a kind of filtration drain valve, and the existing drain valve of solution does not have filtering function and causes influencing the product problem in working life, and has the advantage of convenience for washing.
The technological scheme of the utility model is: a kind of filtration drain valve; Comprise valve body and valve gap, described valve body is provided with suction port, spout and air outlet, and said spout connects suction port and air outlet; Be provided with the spray lid that matches with spout in the said valve gap; The bottom of said valve body is provided with the through hole that communicates with said suction port and spout, is provided with the sleeve column that matches with it in the described through hole, and the end of said sleeve column is provided with groove; Said suction port and air outlet communicate through groove, and the opening of described groove is provided with filter screen.
Said filter screen is processed by ag material.
Said sleeve column is connected with through hole whorl.
Said sleeve column is " circular cone " shape.
The bottom of said filter screen is provided with annular gasket.
Compared with prior art; The utlity model has following beneficial effect: owing on drain valve, set up one deck filter screen; Just can realize double filtration, thereby can effectively filter some impurity in the steam, prevent the working life that its inner member receives the pollution effect product steam.
Description of drawings
Fig. 1 is the outline drawing of the utility model.
Fig. 2 is the sectional view of the utility model.
Fig. 3 is the exploded view of the utility model.
Fig. 4 is the worm's eye view of valve body in the utility model.
Fig. 5 is the structural representation of filter screen in the utility model.
Among the figure, valve body 1, valve gap 2, suction port 3, spout 4, air outlet 5, through hole 6, sleeve column 7, groove 8, filter screen 9, spray covers 10, annular gasket 11.
Embodiment
Be described further to the embodiment of accompanying drawing below the utility model:
Shown in figure, this filters drain valve, comprises valve body 1 and valve gap 2; Described valve body 1 is provided with suction port 3, spout 4 and air outlet 5; Said spout 4 connects suction port 3 and air outlet 4, is provided with the spray lid 10 that matches with spout 4 in the said valve gap 2, and the bottom of said valve body 1 is provided with the through hole 6 that communicates with said suction port 3 and spout 4; Be provided with the sleeve column 7 that matches with it in the described through hole 6; The end of said sleeve column 7 is provided with groove 8, and said suction port 3 communicates through groove 8 with air outlet 4, and the opening of described groove 8 is provided with filter screen 9.According to such scheme, owing on drain valve, set up filter screen 9, filter screen 9 is arranged at the end of sleeve column 7; Steam feeds from suction port 3, gets in the groove 8 through filter screen 9, gets in the spout 4 through filter screen 9 again; Realized the effect of double filtration; Filter screen can one or more layers be formed, thereby can effectively filter some impurity in the steam, prevents the working life that its inner member receives the pollution effect product.
Shown in figure, said filter screen 9 is processed by ag material.The filter screen 9 that adopts ag material to process can effectively prolong its working life, and effectively improves its filtering effect, can certainly adopt materials such as stainless steel, iron.
Shown in figure, said sleeve column 7 is threaded with through hole 6, and said sleeve column 7 be " circular cone " shape, and filter screen 9 is circle and fits with the bottom of through hole 6.Sleeve column 7 and through hole 6 adopts to be threaded and can effectively improve sealability between the two, prevents steam leakage, and is convenient to dismounting, after using a period of time, through turning on sleeve column 7, to filter screen 9 clean, scrubbing.Can effectively keep this drain valve cleaning inside, clean, improve its using effect.
Shown in figure, the bottom of said filter screen 9 is provided with annular gasket 11.Through the bottom at filter screen 9 annular gasket 11 is set, when sleeve column 7 is screwed, realizes installing thereby drive annular gasket 11 makes the bottom of filter screen 9 and through hole 6 fit, annular gasket 11 can effectively play a protective role to filter screen 9.
Embodiment should not be regarded as the restriction to model utility, but any improvement of doing based on the spirit of the utility model, all should be within the protection domain of the utility model.
