Embodiment
Contrast accompanying drawing below, through the description to embodiment, specific embodiments of the invention is done further detailed explanation, to help those skilled in the art inventive concept of the present invention, technological scheme is had more complete, accurate and deep understanding.
Like Fig. 2, the expressed structure of the present invention of Fig. 3, the present invention comprises three-way valve valve body 4, valve piston 1 for a kind of commercial car diesel engine braking system threeway assembly parts.
The threeway assembly parts is threaded with pipeline through air input joint, realizes gas delivery.
One, inventive concept and creationary analysis:
In order to solve the problem that exists at the described present known technology of this specification background technique part and to overcome its defective, realize improving the goal of the invention of product reliability, the technological scheme that the present invention takes is:
Like Fig. 2, shown in Figure 3, make moving lamp switch 10 in the described threeway assembly parts of commercial car diesel engine braking system threeway assembly parts provided by the present invention, described braking light switch 10 is connected with the Stop Lamp of said commercial car.
The present invention carries out Transform Type design and update to the structure of product of the prior art, and the braking light switch device has been installed, and has improved reliability of products, thereby improves performance of products.
Two, the static position of each parts relation among the present invention:
Valve piston 1 is contained in the three-way valve valve body 4.Pipe joint 2 is installed on the three-way valve valve body 4, and realizes sealing through pipe joint packing ring 3.
Described braking light switch 10 is located at the place, valve body air outlet of described threeway assembly parts; Its Placement is: at described three-way valve valve body 4 tee union 6 is set; Two straight-through ports of described tee union 6 are connected with described three-way valve valve body 4 and pilot line respectively, and described braking light switch 10 is installed on the Centronics port of described tee union 6.
Described tee union 6 is installed on described three-way valve valve body 4 and the pilot line through rectangular seal packing ring 9, liner 8 and nut 5, nut 7.
Three, dynamic position relation of the present invention:
Like Fig. 2 and shown in Figure 3, when to a port of threeway assembly parts (left end) air inlet, valve piston 1 is to another port (right-hand member) motion, and with pipe joint 2 contact seals of right-hand member; On the contrary, when gas when right output port gets into, 1 end motion left of valve piston, and with pipe joint 2 contact seals of left end.
Four, working principle of the present invention:
With two independently gas circuit alternately to same gas-pressure component or to a pilot line inflation.When wherein a gas circuit is damaged, can come air feed through another gas circuit, the pipeline gas circuit can normally be moved.And work as service brake or when going, braking light switch 10 is with the bright of control brake lamp or go out.
Five, improvement effect of the present invention:
New structure threeway assembly parts of the present invention has increased braking light switch 10 devices; New structure has been set up tee union 6, rectangular seal packing ring 9, liner 8, nut 5, nut 7 and braking light switch 10 at place, valve body air outlet, has improved performance of products.
Through after the above-mentioned improvement, new structure threeway assembly parts obviously improves than original structure workability and reliability, and rate of fault is reduced to 0.6% by 4.2%.
In sum, the present invention has improved the production capacity and the performance of product, has reduced rate of fault, for the assembling in enormous quantities of various vehicle lays the foundation.
Combine accompanying drawing that the present invention has been carried out exemplary description above; Obviously the concrete realization of the present invention does not receive the restriction of aforesaid way; As long as adopted the improvement of the various unsubstantialities that method of the present invention design and technological scheme carry out; Or design of the present invention and technological scheme are directly applied to other occasion without improving, all within protection scope of the present invention.
