Embodiment
For making the object of the embodiment of the present invention, technological scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technological scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 is the structural representation of the pressure protective device embodiment of discharge pipe line provided by the invention, as shown in Figure 1, comprising:
Water drift 1, valve body 2, solenoid valve 3 and rubber cushion 4;
Water drift 1 is arranged on the top of the solenoid valve 3 of valve body 2 inside, swim on the liquid of valve body 2 inside, switch is provided with in water drift 1, when water drift 1 rises to the first predeterminated position with liquid water level, switch in water drift 1 closes, when water drift 1 drops to the second predeterminated position with liquid water level, the switch opens in water drift 1;
Solenoid valve 3 is arranged on the bottom of valve body 2, floats 1 be connected with water, and when the switch in water drift 1 closes, solenoid valve 3 dead electricity is opened and carried out draining, and when water floats the switch opens in 1, solenoid valve 3 closes;
Rubber cushion 4 is arranged on the bottom of valve body 2, for when external pressure is greater than internal pressure, blocks the drain opening bottom valve body 2.
Wherein, water drift 1 is stainless steel water drift.Solenoid valve 3 mainly through electromagnet adhesive, open control draining and sealing.Solenoid valve 3 is core components of whole pressure protective device, when solenoid valve 3 obtains electric adhesive, is blocked in water route, plays and ensure carriage airtightness effect.After solenoid valve 3 dead electricity, by the pressure of water and the elastic force of spring, water route is communicated with.Rubber cushion 4 is specifically as follows anti-negative pressure silicagel pad, and anti-negative pressure silicagel pad ensures to stop negative pressure to enter compartment in the process of draining.When draining, due to Action of Gravity Field, open silicagel pad, water is discharged.When the outer air pressure of car enters into the drain opening place of solenoid valve base, due to the effect of pressure, silicagel pad upwards pushed away, cover drain opening, pressure is larger, and sealing is better, so just can ensure when draining, and the outer negative pressure of car can not enter compartment.
Further, when water drift 1 rises to the 3rd predeterminated position with liquid water level, the switch in water drift 1 closes, until water drift 1 drops to the 4th predeterminated position with liquid water level;
3rd predeterminated position is higher than the first predeterminated position; Second predeterminated position described in 4th predeterminated position.
