Abstract
The utility model relates to a discharge valve, particularly to an automatic discharge valve with a filtering device. The automatic discharge valve includes a guide rod connected with water outlet equipment, wherein the tail end of the guide rod of the discharge valve body is connected with a sealing valve; the other end of the sealing valve is connected with a pressure spring; drain holes are formed in the discharge valve body; the periphery at the top of the device is wrapped by a filter screen plate; and a plurality of small holes are formed in the outer surface of the filter screen plate. As the small holes are formed in the outer surface of the filter screen plate, sundries smaller than the filter holes can be discharged out of the discharge valve through the screen plate, and sundries larger than the filter holes can not enter the discharge valve; and as the filter screen plate is annular, flexible strip-shaped sundries can only be adhered to the periphery of the screen plate without the possibility of entering the valve, and as the filter holes are formed in the peripheral part and the top of the filter screen plate, the normal drainage of the discharge valve cannot be influenced, and the practicability of the automatic discharge valve can be greatly improved.
Description
Technical field
The utility model relates to a kind of drain valve, relates in particular to a kind of automatic drain valve with filtrating equipment.
Background technique
What fire hydrant of being sold on the existing market and fire-fighting monitor had an automatic drain valve does not all have a filtrating equipment; After much fire_fighting pipe networks have just been built completion; Because what pipe flushing possibly wash is not clean especially; Be prone to exist impurity in the pipeline, cause fire-protection equipment automatic drain valve when work to fit badly easily, leak.
Summary of the invention
In order to overcome above-mentioned defective, the purpose of the utility model is to provide a kind of automatic drain valve of band filtrating equipment of the bottom (as: monitor tower etc.) that can be installed in (as: fire hydrant, fire-fighting monitor etc.) on the water system fire-protection equipment or the pipeline of ascending a height.
To achieve these goals; The utility model adopts following technological scheme: a kind of automatic drain valve with filtrating equipment; It comprises and goes out guide rod, the drain valve body that wetting system is connected, and the tail end of guide rod is connected with seal valve, is connected with stage clip at the other end of seal valve; On said drain valve body, have weep hole, around this device top, be enclosed with screen pack.Outer surface at screen pack has a plurality of apertures.
The utility model is installed on the equipment; Equipment is in when closing state, and this drain valve is in opening state, the opening controlling valve lobe; Press water access arrangement inner chamber; When cavity pressure rises to can seal valve be overcome the elastic force of stage clip the time, automatic drain valve is with automatic sealed drain valve body, and weep hole is with not draining; Equipment quits work behind the closing control flap, and cavity pressure descends, and when the elastic force that drops to stage clip when cavity pressure can overcome the strength of hydraulic pressure, stage clip backed down seal valve, and surplus water is through the weep hole device for transferring in the chamber.
The beneficial effect of the utility model:
Outer surface at screen pack has a plurality of apertures.So less than the foreign material of filtering hole can pass through the foreign material of web plate can expulsion valve outside, and can't get in the drain valve greater than the foreign material of web plate filtering hole; Because screen pack is circular, so soft bar shaped foreign material only can center on attached to the outer of web plate, can't get in the valve, and because filtering hole is all arranged at periphery and top, so also can not influence the normal draining of drain valve.So can improve the practicability of automatic drain valve greatly.

Embodiment
Detail below in conjunction with 1,2,3 pairs of the utility model of accompanying drawing: a kind of automatic drain valve with filtrating equipment; It comprises and goes out guide rod 2, the drain valve body 4 that wetting system is connected; The tail end of guide rod 2 is connected with seal valve 3; The other end at seal valve 3 is connected with stage clip 6, on said drain valve body 4, has weep hole 5, around this device top, is enclosed with screen pack 1.Outer surface at screen pack 1 has a plurality of apertures.
The utility model is installed in out on the wetting system; Go out wetting system and be in when closing state, this drain valve is in opening state, the opening controlling valve lobe; Press water access arrangement inner chamber; When cavity pressure rises to can seal valve 3 be overcome the elastic force of stage clip 6 time, automatic drain valve is with automatic sealed drain valve body 4, and weep hole 5 is with not draining; Equipment quits work behind the closing control flap, and cavity pressure descends, and when the elastic force that drops to stage clip 6 when cavity pressure can overcome the strength of hydraulic pressure, stage clip 6 backed down seal valve 3, and surplus water is through weep hole 5 device for transferring in the chamber.
