The utility model takes the advantages of the water pressure regulation to change the original way of water inlet and outlet so that a piston is not to get loose because of the water pressure and the water-leakage is thus avoided. The utility model improves the reliability of the electric spraying valve, is simple in structure, easy in operation and achieves good operational result.

Description

The water spray control gear of electrical water jetting valve

Technical field

The utility model relates to a kind of auto parts and components, especially a kind of water spray control gear of electrical water jetting valve.

Background technique

At present, the brake drum of automobile cools off general Lever type and the pneumatic type of adopting, and the structure of this dual mode is more complicated all, and trouble is installed, poor reliability, and use is very inconvenient, traffic safety is caused a hidden trouble, so occurred DYN dynamic spray water valve now.Chinese patent discloses a kind of " electrical water jetting valve " for No. 94212508.8, and it simple in structure installed easily, it is also convenient to use, but because solenoid valve is to push down piston by the pressure of spring to block water outlet, when hydraulic pressure during greater than spring pressure, piston can become flexible to cause and leak.

The model utility content

The technical problems to be solved in the utility model is, a kind of water spray control gear of electrical water jetting valve is provided, and this apparatus structure is simple, good reliability, easy to operate, and guarantees can not leak because hydraulic pressure increases.

The technical solution of the utility model is, the top connecting coil base (14) of housing (1), and coil base is provided with solenoid valve (15); Annular wall (7) is arranged on the downside inwall of housing (1), and lead to water outlet (6) housing (1) below, and water outlet (6) is in the inwall scope of belt wall (7); Annular wall (7) upper end contacts with sealing gasket (3), and packing ring (9) is pressed in sealing gasket (3) on the boss of housing (1), and packing ring (9) top contacts with coil base (14); Chuck (4) is stuck in the middle of the sealing gasket (3), and there is discharge channel (5) at its center, and sealing gasket (3) is provided with water port (8); The diameter of discharge channel (5) is greater than the diameter of water port (8); The sidewall of housing (1) and intake pipe (2) lead to, and the position of intake pipe (2) is in sealing gasket (3) below.

The water spray control gear of described electrical water jetting valve, chuck (4) top are greater than belt wall (7), and chuck (4) bottom is less than belt wall (7).

Be provided with Sealing (10) between aforesaid packing ring (9) top and the coil base (14).

Aforesaid sealing gasket (3) is a rubber gasket.

Compared with prior art, the utility model utilizes the adjustment of hydraulic pressure, has changed original method that discharges water and close water, makes piston can not leak because hydraulic pressure is loosening, has improved the reliability of electrodynamic type spray water valve, and simple in structure, is convenient to operation, and implementation result is good.

Fig. 1 is a structural representation of the present utility model.

Embodiment

Embodiment: the structure of the water spray control gear of electrical water jetting valve as shown in Figure 1, the top connecting coil base 14 of housing 1, coil base is provided with solenoid valve 15; On the downside inwall of housing 1 annular wall 7 is arranged, housing 1 top is connected with coil base 14, and housing 1 below and water outlet 6 lead to, and water outlet 6 is in the inwall scope of the wall 7 that goes in ring; Annular wall 7 upper ends contact with rubber gasket 3 (gasket material is a rubber in this example), top, rubber gasket 3 outer contacts with packing ring 9, bottom, rubber gasket 3 outer contacts with the boss of housing 1 sidewall, packing ring 9 tops contact with housing 1 upper wall, be provided with Sealing 10 between packing ring 9 tops and housing 1 upper wall, rubber gasket 3 be fixed on the sidewall of housing 1 by elastic pressure; Chuck 4 passes rubber gasket 3, chuck 4 tops are greater than belt wall 7, chuck 4 bottoms are less than belt wall 7, the intermediate portion is stuck in the space of rubber gasket 3 centres, there is discharge channel 5 at chuck 4 centers, discharge channel 5 is perpendicular to rubber gasket 3, and the upper end of discharge channel 5 is on rubber gasket 3 tops, and the lower end of discharge channel 5 is in rubber gasket 3 bottoms; Rubber gasket 3 is provided with water port 8, and the sidewall of housing 1 and intake pipe 2 lead to when making water flowing; The diameter of discharge channel 5 is greater than the diameter of water port 8, and the position of intake pipe 2 is in sealing gasket 3 belows.

Housing 1, formed a hydraulic pressure storehouse 11 between annular wall 7 and rubber gasket 3 bottoms, housing 1, coil base 14, rubber gasket 3 tops, formed hydraulic pressure storehouse 12 between the Sealing 16 of chuck 4 and solenoid valve 15 (Sealing 16 is rubber seal), water port 8 guarantees that two storehouses are communicated with, (actual is an electromagnet when solenoid valve 15, on the piston 13 of its bottom seal arrangement is arranged, the groove on top is provided with spring, the seat of ending is arranged at spring top, these parts are the technology parts in the application documents of having announced 94212508.8) on piston 13 and discharge channel 5 on during end in contact, valve is in closed condition, at this moment after feeding water, hydraulic pressure storehouse 11 and hydraulic pressure storehouse 12 all have been full of water, 2 storehouse pressure are basic identical, at this moment, and can water outlet; When electromagnetic coil energising back piston 13 moves up when not contacting with discharge channel 5 upper ends, valve is in opening state, the water in hydraulic pressure storehouse 12 can be discharged by discharge channel 5, because the cross sectional area of discharge channel 5 is greater than the cross sectional area of water port 8, the drainage rate in hydraulic pressure storehouse 12 is greater than water intake velocity, at this moment the pressure in hydraulic pressure storehouse 12 reduces, rubber gasket 3 is subjected to the pressure in hydraulic pressure storehouse 11 greater than the pressure that is subjected to hydraulic pressure storehouse 12, so being pushed to, heaves rubber gasket 3, do not contact with annular wall 7 upper ends, produce a space, the water in hydraulic pressure storehouse 11 flows to water outlet 6 from the space, when piston was closed, the pressure in hydraulic pressure storehouse 12 increased, end in contact on rubber gasket 3 reinstatements and the belt wall 7, water stops to flow out.In the course of the work, rubber gasket 3 can be used as Sealing when not draining, and water is spilt.Chuck 4 tops greater than annular wall 7 so that when valve cuts out, rubber gasket 3 can be pressed on annular wall 7 upper ends.
