Abstract
This utility model relates to square electric control valve which is the gas circuit on-off element widely used in the railway locomotive, firstly, the appearance of magnet yoke cylinder is square and a valve is combined to the ladder shape with a valve seat, which can't only be favorable to installation, but favorable to enhance the general performance of valve because the increasing of wall thickness of magnet yoke cylinder can be met; secondly, the over voltage absorption device integrating coil plug is provided, the rheostat and coil is paralleled, which can attenuate voltage and current.
Description
Technical field
The utility model relates to a kind of square electrically-controlled valve, and it is to be applicable to the gas transmission commanding apparatus of railway electric locomotive, internal combustion locomotive, electric motor car group and the switching element of electric controlled brake system.
Background technique
Electrically-controlled valve is to utilize the electrically operated valve of DC electromagnet control gas circuit switching.Originally 2/2-way, its helix tube type coil case of two-bit triplet electrically-controlled valve of locomotive use all adopt cylindrical yoke tube, and be not only conservative stiff on the profile, and overvoltage protection device is external, need set up a transition plate and install, and these defectives must overcome.
Summary of the invention
The purpose of this utility model is to design the electrically-controlled valve that the new and original and performance of a profile also is better than cylindrical product for users such as electric locomotive factories.
The technical solution of the utility model is---the profile of yoke tube made square, and made simplified and valve seat stepped; Rheostat and coils from parallel connection of coils are set and coil plug overvoltage absorption plant that integrate, that comprise rheostat and four commutation diodes; Electrically-controlled valve wiring place also be provided with whether be used to observe electric light emitting diode.
Above-mentioned rheostat is a MY31 type Zinc-oxide piezoresistor.

2, have the air of pressure to enter actuator it started working; In case dead electricity, valve 14 and 15, valve rod 9, core bar 7 and moving iron core 3 will move upward under the effect of Returnning spring 13 recuperabilities, and suction port P is plugged, relief opening O
1, O
2Be opened, active chamber is in pressure-less state, and actuator quits work.Among the figure, δ A=1mm, δ B=2mm, δ C＜1mm.
As seen from the figure, yoke tube 2 profiles of the present utility model are square, and cylindrical shell and valve seat 8 are stepped, and not only beautiful shape is generous, and be particularly suitable for being contained in the electric locomotive brake control cabinet, thereby the suitable increase that also helps yoke tube material wall thickness improves the electrically-controlled valve overall performance; In addition; this electrically-controlled valve belongs to inductive load; when cut-offfing, higher switching overvoltage will be arranged; for making its coil working normal; remove the diode place that selects the high voltage grade for use; corresponding inhibition protective measure also need be arranged; the moment inverse electromotive force that we produce when adopting rheostat 21 and coil 5 circuit in parallel with effective absorption electrically-controlled valve dead electricity here; simultaneously; use four diode rectifications also to solve the easy misloading of direct current both positive and negative polarity and cause the reverse problem of electromagnetic force, indication also is beneficial to whole operation as working power with light emitting diode 22.Rheostat 21 is MY31 type Zinc-oxide piezoresistors.
