Abstract
The utility model relates to an air pressure regulator, which belongs to the technical field of automotive vehicle braking system. The air pressure regulator comprises a regulator valve body, a regulator valve cap and a regulator core bar assembly; wherein a downward concave core bar vent channel is produced in the central position of the regulator valve body, the regulator core bar assembly is installed in the central hole of the regulator valve body, an air vent is arranged at the bottom of the regulator core bar assembly, an air inlet and an air outlet are arranged on the valve body, and an air conveying channel is produced in the center of the core bar. When compressed air is input from the air inlet, when the intake pressure reaches a certain value, the valve core assembly moves upward, and the compressed air is output from the air outlet via the air conveying channel; when the intake pressure descends to a certain value, the valve core assembly moves downward under the pressure of a pressure regulating spring, and the compressed air at the air inlet is discharged to the atmosphere from an exhaust valve, thereby effectively preventing overpressure or under-pressure of the braking system, ensuring the pressure stability of the braking system, and solving the problems of complex structure and poor sensitivity of the existing regulator.
Description
Technical field:
The utility model relates to a kind of barometric regulator, belongs to the motor vehicle braking systems technical field.
Background technology:
Barometric regulator is to be used for automatic guidance pressure system operation pressure, prevents that the brake system operation pressure is too high or too low, the device that self-propelled vehicle can effectively be braked in motion.Its principle of work is imported by admission port for the pressurized air of coming from source of the gas, and gas pressure is below the diaphragm of core bar assembly, when air pressure reaches 700-730KPa, the core bar assembly overcomes the pressure upward movement of pressure spring, drain tap is closed, and air intake valve is opened, and makes the Air compressor unloading.When input port pressure was reduced to 560-600KPa, the core bar assembly moved downward under the pressure effect of pressure spring, and air intake valve is closed, and drain tap is opened, and Air compressor is started working, once more to the input port air feed.Though existing barometric regulator can play brake action when motor-driven vehicle going, exist complex structure, sensitieness is poor, inconvenient maintenance, weak points such as cost height.
Summary of the invention:
The purpose of this utility model is, provides a kind of simple in structure, and Installation and Debugging are convenient, highly sensitive barometric regulator.
The utility model is to realize above-mentioned purpose by the following technical solutions:
A kind of barometric regulator, it is by the regulating control valve body, regulating control core bar assembly, the regulating control valve gap, pressure spring, adjusting screw(rod) constitutes, it is characterized in that: the center of regulating control valve body is shaped on the core bar air channel to lower recess, regulating control core bar assembly is installed in the regulating control valve body centre hole, and the bottom of centre hole is provided with exhausr port, and drain tap is equipped with in the exhausr port top; The regulating control valve body is provided with admission port and delivery port, and core bar center and both sides are provided with gas distribution channel; The regulating control valve gap is installed on the regulating control valve body by bolt of rear end plate.Adjusting screw(rod) is equipped with at the top of regulating control valve gap, and pressure spring is equipped with in the inside of regulating control valve gap, and pressure spring is fitted and connected with regulating control core bar assembly and adjusting screw(rod) respectively.Described admission port and core bar air channel connect, and described gas distribution channel and delivery port connect.Be provided with air intake valve in the described admission port.
The utility model beneficial effect compared with prior art is:
The utility model is that the pressurized air of coming from source of the gas is imported by admission port, act on below the diaphragm of regulating control spool, when the air inlet pressure reached certain value, regulating control core bar assembly overcame the pressure upward movement of pressure spring, and pressurized air is exported from delivery port by gas distribution channel.When intake pressure drops to certain value, regulating control core bar assembly moves downward under the pressure of pressure spring, air inlet valve is closed, open blow off valve, the pressurized air of admission port is arranged to atmosphere by blow off valve, actv. has prevented that too high or too low problem from appearring in the brake system operation pressure, has guaranteed the stability of brake system.Also have simultaneously simple in structure, the sensitieness height, easy to maintenance, the advantage that productive costs is low.
Description of drawings:
Fig. 1 is the contour structures scheme drawing of barometric regulator;
Fig. 2 is the sectional structure scheme drawing of barometric regulator.
Among the figure: 1, adjusting screw(rod), 2, the regulating control valve gap, 3, pressure spring, 4, delivery port, 5, regulating control core bar assembly, 6, the core bar air channel, 7, the regulating control valve body, 8, gas distribution channel, 9, air intake valve, 10, drain tap, 11, admission port, 12, exhausr port.
The specific embodiment:
This barometric regulator is by regulating control valve body 7, regulating control core bar assembly 5, regulating control valve gap 2, pressure spring 3, adjusting screw(rod) 1 constitutes, and the center of regulating control valve body 7 is shaped on the core bar air channel 6 to lower recess, and regulating control core bar assembly 5 is installed in the centre hole of regulating control valve body 7, the bottom of centre hole is provided with exhausr port 12, and drain tap 10 is equipped with in exhausr port 12 tops; Be symmetrically arranged with admission port 11 and delivery port 4 on the regulating control valve body 7, admission port 11 connects with core bar air channel 6.Air intake valve 9 is installed in the admission port 11.Core bar center and both sides are provided with gas distribution channel 8; Gas distribution channel 8 connects with delivery port 4.Regulating control valve gap 2 is installed on the regulating control valve body 7 by bolt of rear end plate, and the top of regulating control valve gap 2 is equipped with adjusting screw(rod) 1, and pressure spring 3 is equipped with in the inside of regulating control valve gap 2, and is fitted and connected with regulating control core bar assembly 5 and adjusting screw(rod) 1 respectively.
During the utility model work, import by admission port 11 from the pressurized air that source of the gas comes, act on below the diaphragm of regulating control core bar assembly 5, when air pressure reaches 700-730KPa, regulating control core bar assembly 5 overcomes the pressure upward movement of pressure spring 3, air intake valve 9 is opened, and drain tap 10 is closed, and delivery port 4 has pressurized air output.When intake pressure was reduced to 560-600KPa, regulating control core bar assembly 5 moved downward under the pressure effect of pressure spring 3, and air intake valve 9 is closed, and drain tap 10 is opened, and the pressurized air row of delivery port 4 is to atmosphere; Prevented that effectively hypertonia or low excessively problem from appearring in brake system, guaranteed the stability of brake system.
