Abstract
The utility model is related to a kind of component sanding valve used for rail vehicle, including valve body and gas blow pipe, and sand storage cavity and clearance hole are provided with valve body, and sand storage cavity top is funnel-form, and sand storage cavity bottom end is communicated with clearance hole；It is characterized in that inwardly setting multiple gas blow pipes by two outsides in the sand storage cavity bottom other end；The length of multiple gas blow pipes is different, so that the gas outlet of gas blow pipe is different from the distance of clearance hole, in the case that thus the pressure and flow of the compressed air in input gas blow pipe are constant, can carry out different stucco amounts, realize component stucco.The utility model has the advantage that the stucco amount of adjustable track vehicle can be carried out, according to the difference of rail vehicle running situation so as to economize on sand, environmental protection.
Description
Technical field
The utility model is related to a kind of sander, more particularly to a kind of sander used for rail vehicle.
Background technology
Current track vehicle is with the important component that sanding valve is rail vehicle sand sprayer, for the control to stucco above track
System, it includes valve body and gas blow pipe, and sand storage cavity and clearance hole are provided with valve body, and sand storage cavity top is funnel-form, sand storage cavity bottom
Portion one end is communicated with clearance hole, and the other end of sand storage cavity bottom is provided with gas blow pipe, for inputting compressed air；This is used for rail vehicle
Sanding valve is arranged on sand reservoir box lower end, sand storage cavity is connected with sand reservoir box, sand falls into sand storage cavity；During stucco, outside clearance hole
Sand pipe is connect, compressed air is blown out by gas blow pipe, the sand in sand storage cavity is blown into external stucco flexible pipe through clearance hole enters
Row stucco；Existing sanding valve used for rail vehicle is invariable in the air pressure and tolerance of air blowing due to only one of which gas blow pipe
In the case of, sand production rate is constant.And rail vehicle can run into a variety of situations in the process of running, such as sleet sky,
Climb and fall, wheel-slip, idle running etc.；Requirement of the different situations to stucco amount can be different, existing in order to ensure safety
Sanding valve used for rail vehicle stucco can only be come with fixed maximum stucco amount, increase the cost of operation, cause environmental pollution.
The content of the invention
For above-mentioned shortcoming, the purpose of this utility model be to provide it is a kind of can be according to rail vehicle running situation not
Together, the component sanding valve used for rail vehicle of stucco amount is adjusted；So as to economize on sand, environmental protection.
Technology contents of the present utility model are, a kind of component sanding valve used for rail vehicle, including valve body and gas blow pipe, in valve
Sand storage cavity and clearance hole are provided with body, sand storage cavity top is funnel-form, and sand storage cavity bottom end is communicated with clearance hole；It is characterized in that
Multiple gas blow pipes are inwardly set by two outsides in the sand storage cavity bottom other end；The length of multiple gas blow pipes is different, so that blowing
The gas outlet of pipe is different from the distance of clearance hole, thus the pressure and the constant feelings of flow of the compressed air in input gas blow pipe
Under condition, different stucco amounts can be carried out, component stucco is realized, reaches and economizes on sand, the purpose of environmental protection.
The utility model have the advantage that compared with prior art for：The utility model dexterously utilizes the literary mound of air-flow
In effect（venturieffect）：This effect refers to：Low pressure can be produced near swiftly flowing fluid, so as to produce suction
Attached effect.When sanding valve works, air-flow is blown out from gas blow pipe, and air-flow is by sand storage cavity, because " Venturi effect " produces absorption
Effect, air-flow adsorbs the sand in sand storage cavity, stucco is realized into external stucco flexible pipe by clearance hole.The work of this sanding valve
When making, blown by the gas blow pipe to diverse location, the control to sand production rate size can be achieved.1st, the air blowing mouth of pipe separates out sand hole
Distance and the relation of sand production rate：When air-flow is from when separating out the sand hole air blowing mouth of pipe blowout of position farther out, air-flow passes through sand storage cavity
Length is big, and the sand of air-flow absorption is just more；Conversely, when air-flow is blown out from the air blowing mouth of pipe for separating out sand hole closer location, air-flow leads to
The length for crossing sand storage cavity is small, and the sand of air-flow absorption is just few.2nd, relation of the gas blow pipe in middle and both sides and sand production rate：When air-flow from
During close to middle gas blow pipe blowout, air-flow passes through in the middle of sand storage cavity, and the sand of air-flow absorption is just more；Conversely, when air-flow from by
During the gas blow pipe blowout of nearly both sides, air-flow passes through from the side of sand storage cavity, and the sand of air-flow absorption is just few.So as to which this sanding valve exists
In the case that the pressure and flow of input compressed air are constant, by being blown to different gas blow pipes, it can realize big to sand production rate
Small control, realizes component stucco.

Embodiment
Such as Fig. 1 as shown in Figures 2 and 3：A kind of component sanding valve used for rail vehicle, including valve body 1 and gas blow pipe 1.3,
Sand storage cavity 1.1 and clearance hole 1.2 are provided with valve body 1, the top of sand storage cavity 1.1 is funnel-form, and the bottom end of sand storage cavity 1.1 is with shaking out
Hole 1.2 is communicated；It is characterized in that inwardly setting multiple gas blow pipes 1.3 by two outsides in the bottom other end of sand storage cavity 1.1；It is multiple to blow
The length of pipe 1.3 is different, so that the gas outlet of gas blow pipe 1.3 is different from the distance of clearance hole 1.2.
Claims (1)
1. a kind of component sanding valve used for rail vehicle, including valve body and gas blow pipe, are provided with sand storage cavity and clearance hole, storage in valve body
Sand chamber top is funnel-form, and sand storage cavity bottom end is communicated with clearance hole；It is characterized in that in the sand storage cavity bottom other end outside two
Multiple gas blow pipes are set in lateral；The length of multiple gas blow pipes is different, so that gas outlet and the distance of clearance hole of gas blow pipe
Difference, in the case that thus the pressure and flow of the compressed air in input gas blow pipe are constant, can carry out different stucco amounts,
Realize component stucco.
