Wheel paddle type quick opening blind plate
LSM type of paddle wheel type I produced fast opening blind plate (Patent No.: ZL03210870.2), using coaxial double blind plate, which is characterized by the forward blind shaft is stationary by using screw drive back board to produce a rotating wheel propeller inclined forward thrust, push ahead blind plate translational compression seal a blind closed lock to achieve. In order to ensure that the blind plate and the sealing parts without relative motion, to avoid the blind plate and seal friction, resulting in leakage of seal damage. In addition, the wheel propeller type fast opening blind plate also has two pressure relief and safety interlock (shock, anti loosening) function, when the cylinder is also with residual pressure, the blind plate can not be opened, more to ensure the safety of the operation.
1, simple structure, fast switching. The structure is simple, the switch only when the hub of the recess, with wrench screw 90-720 degrees, ensure an operator does not need any special tools in the case of a minute opening blind plate, safety, no leakage.
必中彩票注册2, coaxial double plate, dynamic seal。 The quick opening blind plate rotating part and sealing part of coaxial double plate, the rotation of the bevel board produced by forward thrust, push forward the blind plate translational displacement, the sealing ring is squeezed, so as to achieve the translational sealing state, the seal without any wear damage。
3, linkage locking, safe and reliable。 Close in place (otherwise the safety interlock mechanism can not be loaded), into the safety interlock, meet the full lock on the scheduled operating parts of the rear can boost, or can not boost。 Safety interlock mechanism is arranged after the skull cannot rotate; the system after discharge, must first open the safety interlock mechanism, so that the internal pressure vessels all after discharge, can open the motion of the skull, or can not open。
