Service braking air supply duct 1-a has two air inlets and a gas outlet, selects one of them inlet charge, and another air inlet is blocked.
The top of described valve body 1 has laterally turnover through hole 1-a-4, have on valve body 1 end face and the apical pore 1-a-5 that laterally turnover through hole 1-a-4 communicates, laterally turnover through hole 1-a-4 and apical pore 1-a-5 forms service braking air supply duct 1-a, one aperture of laterally turnover through hole 1-a-4 of service braking air supply duct 1-a and the aperture of apical pore 1-a-5 are respectively the first air inlet 1-a-1 and the second air inlet 1-a-2 of service braking air supply duct 1-a, and laterally another aperture of turnover through hole 1-a-4 is gas outlet 1-a-3.Above-mentioned first passage 1-c-1 is in and laterally transfers between through hole 1-a-4 and slide block chamber 1-c.
The first air inlet 1-a-1 and the second air inlet 1-a-2 of service braking air supply duct 1-a is separately positioned on the leading flank I of valve body 1 and on the end face of valve body 1, the gas outlet 1-a-3 of service braking air supply duct 1-a is arranged on the right flank II of valve body 1.Service braking air supply duct 1-a uses the first air inlet 1-a-1 air inlet, and the second air inlet 1-a-2 is then blocked by upper screw plug 3, is provided with sealing ring 4 between the openning being blocked the i.e. aperture of apical pore 1-a-5 and upper screw plug 3.
Parking braking air supply duct 1-b has two air inlets, selects one of them inlet charge, and another air inlet is blocked.
The bottom of described valve body has cross-drilled hole 1-b-5, the the second bottom outlet 1-b-4 connected with cross-drilled hole 1-b-5 is had on the bottom surface of valve body, cross-drilled hole 1-b-5 and the second bottom outlet 1-b-4 forms parking braking air supply duct 1-b, and the aperture of the second bottom outlet 1-b-4 and the aperture of cross-drilled hole 1-b-5 are respectively the first air inlet 1-b-1 and the second air inlet 1-b-2 of parking braking air supply duct 1-b.The gas outlet 1-b-3 of parking braking supply extension road 1-b-0 is the gas outlet of parking braking air supply duct 1-b.
The first air inlet 1-b-1 and the second air inlet 1-b-2 of parking braking air supply duct 1-b are separately positioned on bottom surface and leading flank I, and parking braking supply extends the gas outlet 1-b-3 i.e. gas outlet of parking braking air supply duct in road and is arranged on right flank II.Parking braking air supply duct 1-b uses the first air inlet 1-b-1 air inlet, and the second air inlet 1-b-2 is then blocked by lower screw plug 5, is provided with sealing ring 4 between the openning being blocked the i.e. aperture of cross-drilled hole 1-b-5 and lower screw plug 5.
Cross-drilled hole 1-b-5 on above-mentioned valve body runs through post and blocks up 1-2, and the post that above-mentioned second passage 1-c-2 is between cross-drilled hole 1-b-5 and slide block chamber 1-c blocks up on 1-2 position, blocks up formation inverted T-shaped hole on 1-2 at post.
When slide block 2 is in the upper/lower terminal of slide block chamber, when i.e. slide block 2 is in the upper and lower that parking braking supplies the air inlet extending road 1-b-0, it is to expose that now parking braking supply extends the air inlet of road 1-b-0.When slide block 2 is in the upper end of slide block chamber 1-c, parking braking air supply duct 1-b extends road 1-b-0 with parking braking supply and connects (see figure 8), when slide block 2 is in the lower end of slide block chamber 1-c, service braking air supply duct 1-a extends road 1-b-0 with parking braking supply and connects (see figure 9).
The gas outlet 1-a-3 of the service braking air supply duct of anti-the Sandwich plate valve 20 and gas outlet 1-b-3 of parking braking air supply duct is arranged on the right flank II of valve body 1, the plane that right flank II is processed mistake of valve body 1.
See Fig. 1, anti-Sandwich plate valve A is connected on the platform 10-4 of brake cylinder body 10 by 3 bolts 11, the right flank plane of valve body 1 and the platform 10-4 of brake cylinder body 10 are affixed, service braking cylinder air inlet 10-a on the gas outlet 1-a-3 and brake cylinder body platform 10-4 of service braking air supply duct coincide, and parking braking supply extends the parking braking cylinder air inlet 10-b on the gas outlet 1-b-3 and brake cylinder body platform 10-2 in road and coincide.
When car normally travels (not braking), by air inlet 1-b-1 to parking braking air supply duct 1-b insufflation gas, gas enters slide block chamber 1-c by the second passage 1-c-2, air pressure promotes slide block 2 to move upward and the first passage 1-c-1 is blocked (see figure 8), parking braking air supply duct 1-b extends road 1-b-0 with parking braking supply and connects, gas extends road 1-b-0, parking braking cylinder air inlet 10-b by parking braking supply and enters parking braking cylinder, air pressure overcomes spring force to compress bullet, to spring stores energy.
During train service braking, by air inlet 1-a-1 to service braking air supply duct 1-a insufflation gas, gas enters service braking cylinder from the gas outlet 1-a-3 of service braking air supply duct 1-a, service braking cylinder air inlet 10-a, air pressure is converted into piston thrust, piston thrust is transmitted by the power of the internal series of complex of brake rigging, it is eventually converted into train service braking power, it is achieved Brake stop.The parking braking air pressure provided because of train is typically larger than service braking air pressure, air pressure in i.e. parking braking air supply duct 1-b is more than the air pressure in service braking air supply duct 1-a, therefore slide block 2 is constantly in slide block chamber 1-c upper end and blocks the first passage 1-c-1, the gas of parking braking air supply duct 1-b extends road 1-b-0, parking braking cylinder air inlet 10-b by slide block chamber 1-c, parking braking supply and enters parking braking cylinder, makes parking braking cylinder be in compression spring energy storage state.During train parking braking, successively discharge the gas in service braking cylinder and parking braking cylinder, the energy of release parking braking cylinder spring store, it is achieved parking braking.Before service braking cylinder and parking braking gas in the jar drain, slide block 2 is constantly in slide block chamber 1-c upper end and blocks the first passage 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 to discharge the gas in parking braking cylinder the most in advance, when the air pressure of parking braking cylinder is less than the air pressure of service braking cylinder, it is in the slide block 2 of slide block chamber 1-c upper end to drop to the lower end of slide block chamber 1-c and blocked by the second air inlet 1-c-2, now service braking air supply duct 1-a connects with parking braking supply extension road 1-b-0, gas passes through service braking air supply duct 1-a, slide block chamber 1-c, parking braking supply extends road 1-b-0, parking braking cylinder air inlet 10-b enters parking braking cylinder, again spring stores energy is given, release parking braking, 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 air inlet 1-a-2 air inlet of service braking air supply duct 1-a in the second embodiment, the first air inlet 1-a-1 is then blocked by upper screw plug 3, is provided with sealing ring 4 between the openning and the upper screw plug 3 that are blocked.The second air inlet 1-b-2 air inlet of parking braking air supply duct 1-b, the first air inlet 1-b-1 is then blocked by lower screw plug 5, is provided with sealing ring 4 between the openning and the lower screw plug 5 that are blocked.Remaining is same as in Example 1.
The third embodiment (omission view) of anti-Sandwich plate valve 20 uses the second air inlet 1-a-2 air inlet of service braking air supply duct 1-a, first air inlet 1-a-1 is then blocked by upper screw plug 3, parking braking air supply duct 1-b uses the first air inlet 1-b-1 air inlet, and the second air inlet 1-b-2 is then blocked by lower screw plug 5.
4th kind of embodiment (omission view) of anti-Sandwich plate valve 20 uses the first air inlet 1-a-1 air inlet of service braking air supply duct 1-a, and the second air inlet 1-a-2 is then blocked by upper screw plug 3.The second air inlet 1-b-2 air inlet of parking braking air supply duct 1-b, the first air inlet 1-b-1 is then blocked by lower screw plug 5.
