Detailed Description
The following detailed description of the embodiments of the invention, given by way of example only, is presented in the accompanying drawings to aid in a more complete, accurate, and thorough understanding of the inventive concepts and aspects of the invention by those skilled in the art.
The structure of the invention shown in figure 1 is a control valve of a trailer of a port machinery braking system.
In order to overcome the defects of the prior art and realize the aim of simplifying the structure of the control valve, the invention adopts the following technical scheme:
as shown in fig. 1, on the valve body of the trailer control valve, an air inlet 8 of a foot valve, a first air inlet 11 of the foot valve, a second air inlet 10 of the foot valve, a first air outlet 6 and a second air outlet 7 are arranged;
the first air outlet 6 is connected with a manual brake joint of the trailer; the second air outlet 7 is connected with a trailer foot brake joint;
the air inlet 8 of the switch valve is communicated with the second air outlet 7;
the contact part of the piston 4 and the valve body forms a valve port 5; the valve port 5 is closed under the action of the pushing piston 4 of the spring 3; under the action of air pressure of an air inlet 8 of the foot valve, the valve port 5 is opened, and a first air inlet 11 of the foot valve and a second air inlet 10 of the foot valve are communicated with an air passage of the first air outlet 6.
The valve controlled by the foot brake valve and the switch valve is completely different from the structure in the prior art, realizes trailer braking, has very simple structure, reduces the volume of the product, reduces the weight to 0.35kg, and has the volume of 52 multiplied by 72 multiplied by 120, and is connected in a brake pipeline of a tractor through 2-phi 9 during connection.
The piston 4 faces to one end of the air inlet 8 and the second air outlet 7, a piston inner cavity 12 is arranged, and the piston inner cavity 12 is a counter bore coaxial with the piston 4.
The valve body is provided with a dustproof diaphragm 1, and the dustproof diaphragm 1 is arranged on a spring seat 2 at the opening of the valve body at the opposite end of a piston inner cavity 12 on a piston 4.
The dustproof diaphragm 1 is connected to the spring seat 2 through a screw; the spring seat 2 is fixed in the valve body through a retainer ring for holes.
A spring 3 is arranged between the piston 4 and the spring seat 2, and the function of the spring 3 is to close the valve port 5.
