Specific embodiment
To keep the purpose of this utility model, technical solution and advantage clearer, clear, develop simultaneously implementation referring to the drawings
The utility model is further described in example.
A kind of hydrostatic foot valve as shown in Figure 1, Figure 2, Figure 3 shows, including for trampling foot valve 100, be set to foot
It steps on inside valve 100 and executes 200 lower end of valve block assembly for receiving to instruct and execute the execution valve block assembly 200 of movement and be set to
Oil pipe 300 for going rancid.
Foot valve 100 includes pedal 110, valve body, the lever body 130 being installed on pedal 110, lever shaft 140 and installation
In the lever seat 150 on valve body, lever seat 150 is connect with lever body 130 by lever shaft 140, is provided with below lever body 130
Clamping screw 160 for locking lever body 130.Specifically, oil pipe 300 is low pressure pipe.
Foot valve 100 divides for left threading valve and right threading valve, and intermediate connection is provided between left threading valve and right threading valve
Body 400, left threading valve is consistent with right threading valve arrangement, ensure that the reliability of device.First annular seal space 121 is opened up in valve body,
121 upper end of first annular seal space sets seal cartridge 122, and lower end is the hydraulic fluid port 500 for connecting low pressure pipe 300.First annular seal space
It is set in 121 and spool mechanism is installed, spool mechanism includes mandril 123, the first spool 124, adjustment spring 125, reset spring 126
And spring base 127.Mandril 123 is installed in seal cartridge 122, and spring base 127 is installed in the lower end of mandril 123, spring base 127 with
The connection of first spool 124, the periphery mounting and adjusting spring 125 of the first spool 124, reset spring 126 is installed on adjustment spring
The upper end of 125 periphery, adjustment spring 125 is contacted with spring base 127, adjusts the first sealing in the lower end and valve body of spring 125
Chamber 121 contacts.The upper end of spool mechanism is pierced by lever seat 150.
