Abstract
The invention relates to a quick mounting wafer type butterfly valve which comprises a wafer type handle, a valve body, a valve rod and a valve plate. The valve rod is coaxially mounted in the valve body in a sleeved manner. The lower portion of the valve rod is coaxially provided with the valve plate in a sleeved manner. A bearing, an O-type ring, a bush, a lower gasket, a check ring, an upper gasket and a snap spring are sequentially mounted on the upper portion of the valve rod in a sleeving manner. A body of the check ring is an annular ring with an opening. A three-quarter arc-shaped strip hole is coaxially manufactured between the inner edge and the outer edge of the annular ring, and the arc-shaped strip hole and the opening are formed symmetrically. A small seam is manufactured to communicate the arc-shaped strip hole with a center hole and be opposite to the opening, and an inner ring is symmetrically divided by the small seam into two parts. The check ring of the butterfly valve is in a one-piece type, and compared with the two-piece type of a traditional check ring, the check ring is more convenient and faster to mount and is directly arranged on the valve in a sleeving manner; and firmness is achieved, and falling off is not prone to happening.
Description
Technical field
The invention belongs to butterfly valve field, it is related to wafer type butterfly valve, especially a kind of fast-assembling wafer type butterfly valve.
Background technology
Traditional butterfly valve is coaxially formed with an annular groove, in annular groove to prevent valve rod from being extracted out from valve body on valve rod
Setting-in back-up ring, the back-up ring is made (as shown in Figure 4) by symmetrical two panels semi-circular iron plate, by the two panels semi-circular iron plate during installation
Be stuck in the annular groove of valve rod (as shown in Figure 5), then be set with pad and jump ring on valve rod above it successively, jump ring it is outer
The inwall of edge insertion valve body is so as to valve rod is fixed in valve body.The shortcoming of the two-piece type back-up ring is：Because it is two panels annular
Iron plate is assembled, so easily being dropped when installing, the cooperation with valve rod is insecure.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art part, there is provided the rational fast-assembling of a kind of simple structure, design science
Wafer type butterfly valve.
The technical proposal for solving the technical problem of the invention is：
A kind of fast-assembling wafer type butterfly valve, including wafer type handle, valve body, valve rod, valve plate, the coaxial package valve rod in valve body,
In the bottom coaxial package valve plate of valve rod, the top of valve rod successively bearing set, O-ring, bushing, lower gasket, back-up ring,
Upper gasket and jump ring, described its main body of back-up ring are the annular ring of an opening, are coaxially formed between the inner edge of annular ring and outer rim
One 3/4 arc slots, the arc slot is symmetrical arranged with opening, and connection arc slot is relative with opening with centre bore, and to be formed with one small
Seam, crack is by inner ring symmetry division into two parts.
And, described opening both sides are symmetrical and parallel.
And, described back-up ring is made up of elastomeric material.
Advantages and positive effects of the present invention are：
1st, the back-up ring of this butterfly valve is single piece type, compared with the two-piece type of traditional back-up ring, when installation more easily and fast, directly
In female connector, and firmly, it is not easy to drop.
2nd, the back-up ring of this butterfly valve is coaxially formed with one 3/4 arc slots between the inner edge of annular ring and outer rim, the arc slot with open
Mouthful it is symmetrical arranged, connection arc slot is relative with opening with centre bore to be formed with a crack, crack is by inner ring symmetry division into two parts.
Tension force is not only increased, and also enhances aesthetic feeling.

Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings and by specific embodiment, following examples be it is descriptive, no
It is limited, it is impossible to which protection scope of the present invention is limited with this.
A kind of fast-assembling wafer type butterfly valve, including wafer type handle 1, valve body 10, valve rod 8, valve plate 11, the coaxial sleeve in valve body
Dress valve rod, in the bottom coaxial package valve plate of valve rod, the top of valve rod successively bearing set 9, O-ring 7, bushing 6, under
Pad 5, back-up ring 4, Upper gasket 3 and jump ring 2.
Described back-up ring structure as shown in Fig. 2 its main body is the annular ring 17 of an opening, between the inner edge of annular ring and outer rim
Coaxially be formed with one 3/4 arc slots 12, the arc slot is symmetrical arranged with opening 16, connection arc slot and centre bore 15 with
Opening is relative to be formed with a crack 13, and crack is by the symmetry division of inner ring 14 into two parts.
Described opening is that both sides are symmetrical and parallel, and the size of opening be able to be enclosed within valve rod with it and is advisable.
Described back-up ring is made up of elastomeric material, and Fig. 3 is the schematic diagram that this back-up ring is arranged on valve rod.
The body top of this butterfly valve is square plate, applied widely, meets multi-national standard.
Above-described is only the preferred embodiment of the present invention, it is noted that for the person of ordinary skill of the art,
On the premise of inventive concept is not departed from, various modifications and improvements can be made, these belong to protection scope of the present invention.
