Adopt technique scheme; The enclosing cover of the pump housing adopts screw to be connected with housing; And the joint is provided with seal ring; Pump housing mount inlet that so just can guarantee housing and extraneous sealing in use can not take place owing to the interior shell pressure disequilibrium causes situation about can't normally move; Inner cap is with after enclosing cover is connected through screw; It is conflicted and is connected with respect to implementing sealing through sealing gasket between the other end that is connected an end with enclosing cover and the dividing plate; Can guarantee the sealing of dividing plate after being provided with like this, also effectively utilize the space of housing simultaneously, make structure more compact.And be more convenient for installing and dismounting.
The utility model further is set to: be conflict through sealing gasket between inner cap and the dividing plate and be tightly connected; The auxiliary seal part that sealing gasket includes direct hermetic unit and is connected with direct hermetic unit; One side of its direct hermetic unit and enclosing cover are fitted and are sealed; Opposite side and dividing plate are fitted and are sealed, and the auxiliary seal part of sealing gasket is fitted with the side of dividing plate and sealed.
Adopt technique scheme, Sealing has direct hermetic unit and auxiliary seal part, and two hermetic units can improve the sealing between inner cap and the dividing plate, have further guaranteed the sealability between each chamber.
The utility model further is set to: the end place that inner cap is connected with dividing plate is provided with short slot, and the direct hermetic unit of sealing gasket is installed in this short slot.
Adopt technique scheme, setting has promptly made things convenient for the installation of sealing gasket like this, and sealability is better.
Below in conjunction with accompanying drawing the utility model is further described.
