Abstract
The invention relates to a component stuccoing valve for a railway vehicle. The component stuccoing valve comprises a valve body and air blowing pipes, wherein a sand storage chamber and a sand outlet are arranged in the valve body; the upper part of the sand storage chamber is of funnel shape; one end at the bottom of the sand storage chamber is communicated with the sand outlet. The component stuccoing valve is characterized in that a plurality of air blowing pipes are inward arranged from two outer sides at the other end at the bottom of the sand storage chamber; the lengths of the air blowing pipes are different from each other, so that the distances between the air outlets of the air blowing pipes and the sand outlet are different; different stuccoing quantity and component stuccoing can be realized under the condition that the pressure and flow of compressed air inputted to the air blowing pipes are kept unchanged. The component stuccoing valve for the railway vehicle has the advantage that the stuccoing quantity of the railway vehicle can be adjusted according to the different running conditions of the railway vehicle, so that the sand usage is saved and the environment is protected.
Description
Technical field
The present invention relates to a kind of sander, particularly relate to a kind of sander used for rail vehicle.
Background technology
Current track vehicle sanding valve is the vitals of rail vehicle sand sprayer, for the control of stucco above track, it includes valve body and gas blow pipe, valve body is provided with sand storage cavity and clearance hole, sand storage cavity top is funnel-form, sand storage cavity bottom end communicates with clearance hole, and the other end bottom sand storage cavity is provided with gas blow pipe, is used for inputting compression air；This sanding valve used for rail vehicle is arranged on sand reservoir box lower end, makes sand storage cavity connect with sand reservoir box, and sand falls into sand storage cavity；During stucco, at the external sand pipe of clearance hole, compression air is blown out by gas blow pipe, through clearance hole, the sand in sand storage cavity is blown into external stucco flexible pipe and carries out stucco；Existing sanding valve used for rail vehicle is due to only one of which gas blow pipe, and when the air pressure blown and tolerance are invariable, sand production rate is constant.And rail vehicle can run into various different situation in running, such as sleet sky, climb and fall, wheel-slip, idle running etc.；Different situations can be different to the requirement of stucco amount, and in order to ensure safety, existing sanding valve used for rail vehicle can only carry out stucco with fixing maximum stucco amount, increases the cost of operation, causes environmental pollution.
Summary of the invention
For above-mentioned shortcoming, it is an object of the invention to provide a kind of component sanding valve used for rail vehicle that stucco amount according to the difference of rail vehicle ruuning situation, can be regulated；It is thus possible to economize on sand, protect environment.
The technology contents of the present invention is, a kind of component sanding valve used for rail vehicle, including valve body and gas blow pipe, is provided with sand storage cavity and clearance hole in valve body, and sand storage cavity top is funnel-form, and sand storage cavity bottom end communicates with clearance hole；It is characterized by that the other end is by arranging multiple gas blow pipe in two laterals bottom sand storage cavity；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, thus when the compressed-air actuated pressure in inputting gas blow pipe and flow are constant, different stucco amounts can be carried out; realize component stucco, reach to economize on the purpose of sand, protection environment.
The present invention compared with prior art have the advantage that is: the present invention utilizes the Venturi effect (venturieffect) of air-flow dexterously: this effect refers to: can produce low pressure near swiftly flowing fluid, thus producing adsorption.During sanding valve work, air-flow blows out from gas blow pipe, and air-flow passes through sand storage cavity, and owing to " Venturi effect " produces adsorption, air-flow adsorbs the sand in sand storage cavity, enters external stucco flexible pipe by clearance hole and realizes stucco.During the work of this sanding valve, by the gas blow pipe of diverse location is blown, it may be achieved the control to sand production rate size.1, the air blowing mouth of pipe separates out the distance of sand hole and the relation of sand production rate: when air-flow blows out from the air blowing mouth of pipe separating out sand hole position farther out, air-flow is big by the length of sand storage cavity, and the sand of air-flow absorption is just many；Otherwise, when air-flow blows out from the air blowing mouth of pipe separating out sand hole closer location, air-flow is little by the length of sand storage cavity, and the sand of air-flow absorption is just few.2, gas blow pipe is in middle and both sides and sand production rate relation: when air-flow is from when 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 many；Otherwise, when air-flow is from the gas blow pipe blowout near both sides, air-flow passes through from the side of sand storage cavity, and the sand of air-flow absorption is just few.Thus, this sanding valve, when inputting compressed-air actuated pressure and constant flow, by different gas blow pipes are blown, can realize the control to sand production rate size, it is achieved component stucco.

The partial cutaway schematic of Fig. 3 present invention.
Detailed description of the invention
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, being provided with sand storage cavity 1.1 and clearance hole 1.2 in valve body 1, sand storage cavity 1.1 top is funnel-form, and sand storage cavity 1.1 bottom end communicates with clearance hole 1.2；It is characterized by that the other end is by arranging multiple gas blow pipe 1.3 in two laterals bottom sand storage cavity 1.1；The length of multiple gas blow pipes 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 component sanding valve used for rail vehicle, including valve body and gas blow pipe, is provided with sand storage cavity and clearance hole in valve body, and sand storage cavity top is funnel-form, and sand storage cavity bottom end communicates with clearance hole；It is characterized by that the other end is by arranging multiple gas blow pipe in two laterals bottom sand storage cavity；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, thus when the compressed-air actuated pressure in inputting gas blow pipe and flow are constant, can carry out different stucco amounts, it is achieved component stucco.
