Abstract
The utility model discloses a 109-type distributing valve, which belongs to the brake field of trunk line electric locomotives. The 109-type distributing valve comprises a main valve, a mounting seat and a pressure regulating valve, as control pressure of a safety valve in the existing 109-type distributing valve is not high in accuracy and sealing property, the existing channel for charging air into a capacity chamber via a pressure increasing valve from a total air source is changed into an form of charging air into the capacity chamber via the pressure increasing valve after pressure of the total air source outside the distributing valve is adjusted via a pressure adjusting valve, and when in emergency brake, the 109-type distributing valve can accurately control pressure in the capacity chamber, is high in stability and simple in implementing, and simultaneously thoroughly avoids the potential problem that gas in the capacity chamber is leaked via the safety valve.
Description
Technical field
The utility model relates to mains electricity locomotive brake field, especially is a kind of preassembling of locomotive electro-pneumatic brake, is one of execution unit of locomotive electro-pneumatic brake specifically---109 type locomotive distributing valves.
Background technology
What the present domestic mains electricity locomotive overwhelming majority was all installed is DK-1 type electro-pneumatic brake.109 type locomotive distributing valves are major parts of DK-1 type electro-pneumatic brake, as shown in Figure 1, comprise main valve, mount pad, safety valve three parts.As shown in Figure 2, and main valve is made up of main valve portion, balanced portion, pressure charging valve, main valve body.When wherein pressure charging valve is used for emergency braking, improve chamber volume pressure rapidly; As shown in Figure 3, pressure charging valve is made up of pressurized spring, supercharging valve pocket, supercharging spool and supercharging valve gap; Have radial hole on this supercharging spool sidewall, the pressure charging valve cover is pressed in the main valve body, radially has the aperture of eight φ 1mm, and when pressurized spring was compressed, chamber volume was communicated with blast main by this radial hole and these eight apertures; The upside of pressure charging valve is communicated with the train pipe.
When locomotive running and service application position, pressure charging valve is owing to the effect of pressurized spring and train tube pressure is in lower position, and this moment, blast main and chamber volume were obstructed.When emergency braking took place, train tube pressure was discharged rapidly, and the train pipe internal pressure on pressure charging valve top sharply descends, and the chamber volume pressure of its underpart rises rapidly simultaneously.When the pressure of chamber volume reached the less excess pressure of the bounce that can overcome pressurized spring and train pipe, pressure charging valve was in open stance, and at this moment, total wind flows to chamber volume rapidly through supercharging valve pocket radial hole.The pressure of chamber volume is subjected to the control of safety valve, the as prescribed requirement, and during the locomotive emergency braking, chamber volume pressure is 450kPa.When chamber volume pressure reached this numerical value, safety valve promptly moved, and was no more than this specified value to guarantee chamber volume pressure.
Because on the safety valve structure, 2 deficiencies are arranged during existing 109 type distributing valve emergency braking superchargings:
1, during emergency braking,, cause chamber volume blast wandering scope big because safety valve constantly opens and closes.
2, the safety valve leak tightness is relatively poor, and chamber volume still is that service braking all has certain leakage at emergency braking.
In view of above 2 points, be necessary the urgent boosting method of distributing valve is improved.
The utility model content
When having 109 type distributing valve emergency brakings now in order to overcome, chamber volume pressure accuracy is not high, the deficiency of poor stability, the utility model aims to provide a kind of 109 type distributing valves, this distributing valve good leak tightness, and pressure controling precision height are during emergency braking, supercharging is easy, and can make chamber volume pressure more stable.
To achieve these goals, the technical scheme that the utility model adopted is: establish the mount pad of chamber volume in described 109 type distributing valves comprise, be contained in the main valve that includes pressure charging valve on the mount pad; Described pressure charging valve is contained in the pressurized spring in this supercharging valve pocket by the supercharging valve pocket, with the supercharging valve gap that this supercharging valve pocket links to each other, places the supercharging spool between pressurized spring and the supercharging valve gap to form; It is characterized in that, described main valve links to each other with a pressure regulating valve by exterior line, this pressure regulating valve is communicated with chamber volume by supercharging valve pocket radial hole when pressure charging valve is open, blast main in described pressure charging valve and the main valve is not communicated with, this pressure charging valve is connected with pressure regulating valve by inner secret tunnel of main valve and exterior line, and the interior chamber volume of pressure charging valve bottom and mount pad is connected.
The accuracy and the stability of chamber volume internal pressure when improving emergency braking, the utility model has been cancelled the safety valve on the existing 109 distributing valve mount pads, and the passage that will be communicated with between chamber volume and the former safety valve stops up, the passage that is communicated with between blast main and the pressure charging valve is stopped up, and main valve is connected with a pressure regulating valve by pipeline, this pressure regulating valve is communicated with outside blast main, realized to have 109 distributing valves are filled wind to chamber volume through pressure charging valve by total wind path now, change into and fill wind through pressure charging valve to chamber volume again after the utility model is adjusted pressure by the outside total wind of distributing valve through a pressure regulating valve, the particularity height, good stability, the leak tightness function admirable.
Principle of work: at first, stop up the path between the blast main in described pressure charging valve and the main valve; When emergency braking takes place, gas is discharged rapidly in the train pipe, pressure decay, the chamber volume internal pressure rises rapidly, when the pressure of chamber volume overcomes the excess pressure of the bounce of pressurized spring and train pipe, pressure charging valve is in open stance, and pressure regulating valve is communicated with chamber volume by supercharging valve pocket radial hole; The gas pressure regulating valve of flowing through in the blast main, gas is adjusted to setup pressure value by pressure regulating valve after supercharging valve pocket radial hole flows to chamber volume, equals the pressure regulating valve setup pressure value up to chamber volume pressure.
Compared with prior art, the beneficial effects of the utility model are: the utility model replaces safety valve by pressure regulating valve to be controlled the chamber volume internal pressure, implements simply to make chamber volume pressure accurate and stable when emergency braking.Owing to cancelled existing relief valve device, thoroughly avoided the possibility of volume indoor gas, the leak tightness function admirable simultaneously from safety valve escape.
