Description
Technical field:
The utility model relates to a kind of butterfly valve.
Background technique:
The dehydration butterfly valve of GPZ-68 vacuum filter dehydration barrel in use frequently opens and closes, and it is very fast to wear and tear, and it is excessive to wear and tear, and degree of vacuum descends, in order to guarantee degree of vacuum, need be to the butterfly valve integral replacing, and the dismantlement work amount is big, and the time is long, the expense height.Tracing it to its cause is fixedly ring washer unreasonable structure on the butterfly valve, causes wearing and tearing easily.
Summary of the invention:
The purpose of this utility model just provides a kind of butterfly valve.
The purpose of this utility model can realize by following scheme:
The utility model comprises ring washer and cover plate two-part.
The described ring washer rapid wear back-up ring that uses that matches by fixing ring washer with it is formed, and described fixedly ring washer is the concave station structure, and the rapid wear ring washer is a boss structure, just can be inserted in the concave station of fixing ring washer, and described ring washer is installed on the slip tube opening.
Described cover plate is made up of pressing plate, rubber mat plate and inner washer, and the three is affixed by bolt, and cover plate is connected on the slip pipe by hinges.
The utlity model has simple in structurely, expense is low, dismounting, characteristics such as easy to use.
Description of drawings: Fig. 1, the utility model structural representation.
1, fixedly ring washer 2, rubber mat plate 3, pressing plate 4, inner washer
5, bolt 6, hinges 7, slip pipe 8, rapid wear ring washer
Embodiment:
Contrast Fig. 1 as can be known, the utility model comprises ring washer and cover plate two-part, the described ring washer rapid wear back-up ring 8 that uses that matches by fixing ring washer 1 with it is formed, described fixedly ring washer 1 is the concave station structure, and rapid wear ring washer 8 is a boss structure, just can be inserted in the concave station of fixing ring washer, described ring washer is installed on slip pipe 7 ports, described cover plate is made up of pressing plate 3, rubber mat plate 2 and inner washer 4, and the three is affixed by bolt 5, and cover plate is connected on the slip pipe 7 by hinges 6.
The utility model working principle is as follows: in the rapid wear back-up ring is inserted into the concave station of fixing back-up ring, form a unobstructed pipeline with the slip pipe, slip flows through from the rapid wear back-up ring, wear extent concentrates on the rapid wear back-up ring, small amount of wear, the position of adjusting the rapid wear back-up ring can guarantee degree of vacuum, whole rapid wear back-up ring is then changed in serious wearing and tearing, through improving the back butterfly valve, the replacing that changes the rapid wear back-up ring into is changed in the replacing of wear-out part by butterfly valve, simple in structure, expense is low, dismounting, easy to use, and the replacing time is short, improve the equipment effective utilization, prolonged the life-span of butterfly valve.
