Description
Technical field
The utility model relates to the part apparatus structure of a kind of electric locomotive or other locomotive, is the pneumatic control valve of a kind of electric locomotive or other locomotive specifically, is mainly used in the atmospheric control of all kinds of electric locomotives.
Background technique
In the control of electric locomotive or other locomotive, many controls realize by atmospheric control, and majority is to control with two-position three-way valve.For the gas circuit path that will build a more complicated, often need with a plurality of two-position three-way valves or other multidigit multiple-way valves, combination could form.Because the control of locomotive is more and more higher to the requirement of automation now, part with pneumatic control also increases greatly, so the valve of control is also more and more, after the valve of control increased, it is very in disorder that The whole control system just seems, adopts the manual switch inconvenience, installation difficulty also increases, system constitute cost also straight line rise, and be not easy to care and maintenance, therefore necessary this is improved.
The model utility content
The purpose of this utility model is the deficiency at existing locomotive atmospheric control control valve, provides a control more concentrated, and manual switch is convenient, installs simply, and is convenient to the novel locomotive pneumatic control valve of care and maintenance.
The purpose of this utility model is achieved through the following technical solutions: a kind of locomotive pneumatic control valve, the three-position five-way manual switching valve that described locomotive pneumatic control valve is a board mounting structure; Form by valve body, valve pocket, switching button, eccentric rod, plunger, O shape circle, back-up ring, door and sensitive switch etc.
Valve body is a square casing, in housing, be provided with a valve pocket, have in the valve pocket by moving up and down, realize three-position five-way function conversion valve, the plunger of changing valve is positioned at the valve opening of valve pocket, is equipped with O shape circle on the plunger stage by stage, and plunger can move up and down in valve pocket, by the seal action of the O shape on plunger circle, realize each path open or disconnected.Head at plunger has a chute, and eccentric rod is installed in the chute, and eccentric rod is that Vertical direction is connected with plunger, and eccentric rod is with switching button outward, and eccentric rod can rotate under the effect of switching button.Center in switching button and eccentric rod is equipped with spring, and is provided with locating stud.Switching button remains on a certain fixed position under the effect of spring and locating stud, if need dislocation, must earlier switching button be pushed inward, and then rotate 90 °.Unclamp after arriving required working position.This changing valve has individual working position, shows by label, as normal position, redundant bit, spare bit.Because the rotation of switching button can drive the rotation of eccentric rod, and eccentric rod is that Vertical direction is connected with plunger, the rotation of eccentric rod has become moving up and down of plunger, by the seal action that the shape on the plunger is enclosed, realizes opening or breaking of each path.Also have a sensitive switch contact at the top of plunger, when handle position was got to the spare space, the sensitive switch contact arrived stroke topmost, touches sensitive switch, the mechanical location of this moment can be converted to electrical signal output, used for monitoring.
Three-position five-way of the present utility model position is: from 5 gas inlet holes, give vent to anger by 3 holes when the spare space for handle, and all the other holes do not have leakage; From 5 gas inlet holes, give vent to anger by 1 hole when redundant position for handle, and all the other holes do not have leakage; From 5 gas inlet holes, give vent to anger by 4 holes when the normal position for handle; From 1 gas inlet hole, give vent to anger in 2 holes, and all the other holes do not have leakage.
The utility model drives the rotation of eccentric rod by switching button, rotation by eccentric rod drives moving up and down of plunger again, realize the function of a valve three-position five-way, can satisfy the demand of the normal position of manually control, redundant bit, spare bit simultaneously with a valve, simplified operation system greatly, also manual switch is convenient simultaneously, installs simply, and is convenient to care and maintenance.System constitutes cost and also declines to a great extent.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a structural representation side view of the present utility model;
Fig. 3 is a three-position five-way transfer principle schematic representation of the present utility model.
Embodiment
Accompanying drawing has provided an embodiment of the present utility model, and the utility model will be further described below in conjunction with accompanying drawing.
As can be seen, the utility model is a kind of locomotive pneumatic control valve, the three-position five-way manual switching valve that described locomotive pneumatic control valve is a board mounting structure from accompanying drawing; Form by valve body 1, valve pocket 2, switching button 3, eccentric rod 4, plunger 5, O shape circle 6, back-up ring 7, door 8 and sensitive switch 9 etc.
Three-position five-way of the present utility model position is a (see figure 3): from 5 gas inlet holes, give vent to anger by 3 holes when the spare space for handle, and all the other holes do not have leakage; From 5 gas inlet holes, give vent to anger by 1 hole when redundant position for handle, and all the other holes do not have leakage; From 5 gas inlet holes, give vent to anger by 4 holes when the normal position for handle; From 1 gas inlet hole, give vent to anger in 2 holes, and all the other holes do not have leakage.
