Embodiment Construction
[0026] Such as figure 1 Shown, the sealing method of the piston type explosive actuator that the present invention proposes is:
[0027] (1) The first step adopts the radial piston sealing form, and designs two identical sealing grooves on the piston. The piston is used as the base body of the two O-ring seals, and adopts the integrated design idea of sealing and actuating parts. The traditional sealing form is in accordance with the "O-ring rubber seal selection and seal chamber design specification QJ1035.2-86" , Two sealing grooves are designed directly on the piston for installing two O-rings.
[0028] (2) The second step is to add a "explosion relief groove" with a width of 0.5mm to 1mm and a depth of 1mm to 2mm between the two sealing grooves of the piston. The function of this step is: after the explosion of the propellant and explosives, high temperature and high pressure detonation gas is formed. If the first O-ring does not block the detonation gas, it will pass ...
