Abstract
The utility model discloses a multifunctional water supplement valve of an explosion-proof diesel water washing box. The multifunctional water supplement valve comprises a water supplement valve seat, a water supplement connector, a water supplement valve core and a floating ball assembly. The water supplement valve seat is arranged on a water washing box body. The water supplement connector is installed on the outer end portion of the water supplement valve seat. The water supplement valve core is installed on the inner end portion of the water supplement valve seat. A floating ball is arranged on the water supplement valve core through a connecting part. Water outlets are formed in both the water supplement valve core and the water supplement valve seat. In the water supplement valve seat, a sealing valve core is arranged between the water supplement connector and the water supplement valve core. The water outlet in the water supplement valve core and the water outlet in the water supplement valve seat have an overlapped part. According to the multifunctional water supplement valve of the explosion-proof diesel water washing box, the sealing valve core is additionally arranged between the water supplement connector and the water supplement valve seat, sealing reliability is improved, and the water outlet in the water supplement valve core and the water outlet in the water supplement seat have the overlapped part, so that a water supplement box can normally work within four hours, and multifunctional water supplement valve is reliable and stable in work.
Description
Technical field
The utility model relates to a kind of anti-explosion diesel engine water washing box, relates in particular to a kind of anti-explosion diesel engine water washing box Multifunctional water supplementing valve.
Background technique
At present, domestic anti-explosion diesel engine has water washing box, and the purpose of water washing box is mainly to diesel exhaust cooling, and the temperature when guaranteeing that waste gas leaves water tank is lower than 70 ℃, and the water of water washing box is replenished by water-feeding valve by water supply tank.In accordance with regulations, the water supply tank of national trolley-bus must guarantee not add in 4 hours water.The water-feeding valve of domestic water tank-washer adopts directly by end face seal at present.Specific practice is, the moisturizing joint is lengthened, and the rising of moisturizing spool by ball float makes spool that valve is moved to the left water outlet is sealed.Because the water surface in the water washing box is subjected to the impact of waste gas always, water surface site changing up and down, causes ball float also significantly to rock up and down all the time, and therefore when not needing moisturizing, water-feeding valve also can be opened to the water washing box moisturizing.If water washing box water is too many, unnecessary water will be taken out of water washing box by waste gas.So that the water of water supply tank was used less than 4 hours, be subjected to simultaneously the volume restrictions of trolley-bus, water supply tank can not be done very greatly.And the reliability of end face seal is bad, seepage easily occurs.
The model utility content
The purpose of this utility model is to provide a kind of anti-explosion diesel engine water washing box Multifunctional water supplementing valve, and it has the characteristics of good seal performance and reliable and stable work; The problem that exists with the water-feeding valve that solves traditional anti-explosion diesel engine water washing box.
For reaching this purpose, the utility model by the following technical solutions:
A kind of anti-explosion diesel engine water washing box Multifunctional water supplementing valve, it comprises moisturizing valve seat, moisturizing joint, moisturizing spool and floating ball component, described moisturizing valve seat is arranged on the washing casing, described moisturizing jiont treatment is in the outer end of moisturizing valve seat, described moisturizing spool is installed on the inner end of moisturizing valve seat, described ball float is arranged on the moisturizing spool by connected element, all offer water outlet on described moisturizing spool and the moisturizing valve seat, wherein, between moisturizing joint and moisturizing spool, be provided with sealed valve core in the described moisturizing valve seat.
Especially, offer an inner conical surface on the seal face of described moisturizing spool, cooperate inner conical surface to be extended with a sealing projection on sealed valve core, described sealing projection leans on inner conical surface.
Especially, the water outlet on described moisturizing spool and the moisturizing valve seat has intersection.
Especially, the width of described intersection is 2 ㎜.
Especially, described connected element comprises by bearing pin and is articulated in connecting rod on the moisturizing valve seat, and an end of described connecting rod is connected on the moisturizing spool, and the other end is by the nut connecting screw rod, and ball float is installed in the end of described screw rod.
The beneficial effects of the utility model are, compared with prior art described anti-explosion diesel engine water washing box Multifunctional water supplementing valve has installed sealed valve core additional between moisturizing joint and moisturizing spool, and on the moisturizing spool, offer an inner conical surface, sealed valve core withstands on the inner conical surface, greatly improved sealing reliability, water outlet on moisturizing spool and the moisturizing valve seat has an intersection simultaneously, water-feeding valve is just opened when ball float arrives horizontal position, when ball float fluctuates widely up and down, water-feeding valve can not opened, only have when the water washing box water level is lower than designated water level, when ball float reaches bottom position, water-feeding valve just can be opened to water washing box and supply water, to guarantee that water supply tank worked reliable and stable work in 4 hours.
