Abstract
The utility model discloses a double-end-face mechanical seal of a pump valve. The double-end-face mechanical seal comprises a left static ring and a right static ring. A left movable ring and a right movable ring are respectively arranged between the left static ring and the right static ring. An impeller is arranged between the left movable ring and the right movable ring, the right side of the impeller is provided with a left spring base and a right spring base, a spring is disposed between the left spring base and the right spring base, and the right spring base and the right movable ring are arranged in the left spring base in a sliding mode. The double-end-face mechanical seal is simple in structure, convenient to install and use, good in sealing performance, and convenient to maintain.
Description
Technical field
The utility model relates to a kind of pump valve double mechanical seal.
Background technique
In the prior art, in the using process of pump valve, there is irrational place in the structure of pump valve, causes the leakage of pump valve, and complex structure, and processing difficulties exists maintenance inconvenient.
The model utility content
It is a kind of simple in structure, easy to install that the utility model provides, and good sealing effect is maintained easily pump valve double mechanical seal.
The utility model technical solution problem provides following scheme:
A kind of pump valve double mechanical seal, comprise left and right two stationary rings, it is characterized in that: be connected with respectively left and right rotating ring between described left and right two stationary rings, between the described left and right rotating ring impeller is installed, the right side of described impeller is provided with left and right spring seat, between the described left and right spring seat spring is installed, described right spring seat and right rotating ring are slidingly mounted in the left spring seat.
Between described left and right two stationary rings and left and right two rotating rings seal ring is installed.
During the running of the utility model pump, impeller in the mechanical seal and left and right rotating ring rotate together, utilize the effect of centrifugal force, in the spring seat on impeller right side spring is installed, right like this spring seat and rotating ring are together along with the change motion back and forth of pressure, be convenient to maintenance, pump terminal tool seal leakage also can be found easily.
