When car normally travels (not braking), by admission port 1-b-1 to braking during standstill air supply duct 1-b insufflation gas, gas enters slide block chamber 1-c by the second air extractor vent 1-c-2, air pressure promotes slide block 2 upward movement and the first air extractor vent 1-c-1 is blocked (see figure 8), braking during standstill air supply duct 1-b and braking during standstill air feed extend road 1-b-0 and are communicated with, gas extends road 1-b-0, parking braking cylinder admission port 10-b by braking during standstill air feed and enters parking braking cylinder, air pressure overcomes spring force compression bullet, to spring stores energy.
During train service braking, by admission port 1-a-1 to service braking air supply duct 1-a insufflation gas, gas enters service braking cylinder from air extractor duct 1-a-3, the service braking cylinder admission port 10-a of service braking air supply duct 1-a, air pressure is converted into piston thrust, piston thrust is by the power transmission of the inner series of complex of foundation brake rigging, finally be converted into train service braking power, realize stopping-down.The braking during standstill air pressure provided because of train is greater than service braking air pressure usually, namely the air pressure in braking during standstill air supply duct 1-b is greater than the air pressure in service braking air supply duct 1-a, therefore slide block 2 is in slide block chamber 1-c upper end always and blocks the first air extractor vent 1-c-1, the gas of braking during standstill air supply duct 1-b extends road 1-b-0, parking braking cylinder admission port 10-b by slide block chamber 1-c, braking during standstill air feed and enters parking braking cylinder, makes parking braking cylinder be in Compress Spring energy storage state.During train braking during standstill, successively discharge the gas in service braking cylinder and parking braking cylinder, the energy of release parking braking cylinder spring store, realizes braking during standstill.Before service braking cylinder and braking during standstill gas in the jar drain, slide block 2 is in slide block chamber 1-c upper end always and blocks the first air extractor vent 1-c-1; After gas drains, slide block 2 is due to self potential energy, and slide block 2 drops to slide block chamber 1-c lower end.
If because driver operation is improper or error, service braking does not also terminate the gas just discharged in advance in parking braking cylinder, when the air pressure of parking braking cylinder is less than the air pressure of service braking cylinder, second admission port 1-c-2 blocks by the lower end that the slide block 2 being in slide block chamber 1-c upper end drops to slide block chamber 1-c, now service braking air supply duct 1-a and braking during standstill air feed extend road 1-b-0 and are communicated with, gas is by service braking air supply duct 1-a, slide block chamber 1-c, braking during standstill air feed extends road 1-b-0, parking braking cylinder admission port 10-b enters parking braking cylinder, again spring stores energy is given, remove braking during standstill, thus avoid service braking cylinder and parking braking cylinder acts on simultaneously.
Shown in Figure 10 is the second embodiment of anti-Sandwich plate valve 20, and the second admission port 1-a-2 air inlet of service braking air supply duct 1-a in the second embodiment, the first admission port 1-a-1 is then blocked by upper screw plug 3, is provided with seal ring 4 between the openning be blocked and upper screw plug 3.The second admission port 1-b-2 air inlet of braking during standstill air supply duct 1-b, the first admission port 1-b-1 is then blocked by lower screw plug 5, is provided with seal ring 4 between the openning be blocked and lower screw plug 5.All the other are identical with embodiment 1.
The third embodiment (omission view) of anti-Sandwich plate valve 20 adopts the second admission port 1-a-2 air inlet of service braking air supply duct 1-a, first admission port 1-a-1 is then blocked by upper screw plug 3, braking during standstill air supply duct 1-b adopts the first admission port 1-b-1 air inlet, and the second admission port 1-b-2 is then blocked by lower screw plug 5.
