Abstract
The invention discloses a pressure relief and noise reduction safety valve, which comprises a valve body and a spool. An air inlet and air outlets are formed on the valve body; the air outlets are a plurality of vent holes; the spool is slidably arranged inside the valve body; and an elastic compaction piece for tightly pressing the spool to allow the spool to be in sealed fit with the air inlet is arranged between the spool and the valve body. The safety valve can guarantee normal use of an air reservoir, and reduces the noise of the air reservoir during pressure relief and improves the driving comfort of a locomotive driver.
Description
Technical field
The present invention relates to a kind of safety valve, relate in particular to a kind of pressure release noise reduction safety valve.
Background technique
What at present general locomotive was provided with brake device all can use gas receiver, and safety valve all is housed on the gas receiver, when the gas receiver pressure value of reaching capacity, and safety valve unlatching pressure release.But because the air-flow discharge when pressure release of present safety valve is concentrated relatively, be easy to generate bigger noise, influence the travelling comfort of locomotive user steering vehicle.
Summary of the invention
Technical problem to be solved by this invention is: a kind of pressure release noise reduction safety valve is provided, and this safety valve can guarantee the normal use of gas receiver, reduces the noise that gas receiver sends when pressure release, improves the travelling comfort of locomotive user steering vehicle.
For solving the problems of the technologies described above, technological scheme of the present invention is: pressure release noise reduction safety valve, comprise valve body and spool, described valve body is provided with suction port and relief opening, described relief opening is several exhaust ports, described spool is slidingly mounted in the described valve body, is provided with between described spool and the described valve body to compress the elastic pressed piece that described spool and described suction port are sealed and matched.
As a kind of preferred scheme, described exhaust port is six rod radial air vents and the periphery that is evenly distributed on described valve body.
As a kind of preferred scheme, described exhaust port is positioned at described spool and the suction port place that is sealed and matched.
As a kind of preferred scheme, the outer end of described spool is provided with draw ring.
After having adopted technique scheme, effect of the present invention is: because described pressure release noise reduction safety valve, comprise valve body and spool, described valve body is provided with suction port and relief opening, described relief opening is several exhaust ports, described spool is slidingly mounted in the described valve body, be provided with between described spool and the described valve body and compress the elastic pressed piece that described spool and described suction port are sealed and matched, therefore, the suction port of safety valve is communicated with described gas receiver, during work, when the pressure of gas receiver surpasses safety pressure, the pressure that is to say gas receiver just promotes spool during greater than the elastic force of elastic pressed piece and slides, thereby spool is separated with suction port, pressurized gas in the gas receiver are discharged from exhaust port, because exhaust port is several, therefore the discharge of pressurized gas just disperses relatively, pressure during discharge is also lower, from the just reduction of flow velocity of each exhaust port effluent air, like this, the low gas that forces down flow velocity causes the amplitude of vibration and frequency all to reduce to each exhaust port, thereby the noise that causes just reduces, and has accelerated pressure release speed simultaneously, reduces the noise endurance, guarantee the normal use of gas receiver, improve the travelling comfort of locomotive user steering vehicle.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Accompanying drawing is the structural representation of the embodiment of the invention;
In the accompanying drawing: 1. valve body; 11. suction port; 12. relief opening; 2. spool; 3. elastic pressed piece; 4. draw ring.
Embodiment
A kind of pressure release noise reduction safety valve, as shown in drawings, it comprises valve body 1 and spool 2, described valve body 1 is provided with suction port 11 and relief opening 12, described relief opening 12 is several exhaust ports, described spool 2 is slidingly mounted in the described valve body 1, is provided with between described spool 2 and the described valve body 1 to compress the elastic pressed piece 3 that described spool 2 and described suction port 11 are sealed and matched.Described elastic pressed piece 3 is pressure springs, and described pressure spring is squeezed between described valve body 1 and the spool 2, and the spring pressure by spring itself is sealed and matched spool 2 and suction port 11.Preferably, described exhaust port is six rod radial air vents and the periphery that is evenly distributed on described valve body 1.Described exhaust port is positioned at described spool 2 and suction port 11 place that is sealed and matched.The outer end of described spool 2 is provided with draw ring 4.
Working principle of the present invention is: the suction port 11 of safety valve is communicated with described gas receiver, during work, when the pressure of gas receiver surpasses safety pressure, the pressure that is to say gas receiver just promotes spool 2 during greater than the elastic force of elastic pressed piece 3 and slides, thereby spool 2 is separated with suction port 11, pressurized gas in the gas receiver are discharged from exhaust port, because exhaust port is several, therefore the discharge of pressurized gas just disperses relatively, pressure during discharge is also lower, from the just reduction of flow velocity of each exhaust port effluent air, like this, the low gas that forces down flow velocity causes the amplitude of vibration and frequency all to reduce to each exhaust port, thereby the noise that causes just reduces, and has accelerated pressure release speed simultaneously, reduces the noise endurance, guarantee the normal use of gas receiver, improve the travelling comfort of locomotive user steering vehicle.After pressure release was finished, the air pressure in the gas receiver was littler than the elastic force of elastic pressed piece 3, and under the effect of the elastic force of elastic pressed piece 3, spool 2 slides and described suction port 11 is sealed and matched, and safety valve recovers reset condition.
Claims (4)
