Description
Technical field
The invention belongs to field of check valves, are related to the on-line maintenance technology of check-valves, and specifically dress formula is double in one kind
Valve check-valves.
Background technique
Double-disc type check valve is a kind of automatic valve opened and closed by pressure medium, and the country is to Double-disc type now
Side-mounted structure is mainly used when check-valves is installed, therefore when the Double-disc type check valve on pipeline needs to safeguard, it is necessary to
It is removed from pipeline, for the Double-disc type check valve being welded on pipeline, this maintenance mode is cumbersome, and to pipeline and produces
Journey has large effect, can not achieve on-line maintenance.
Summary of the invention
The object of the present invention is to provide formula Bivalved check valve is filled in one kind, so that bivalve Bivalved check valve can be realized online
Maintenance does not have to remove from pipeline that corresponding maintenance work can be carried out, is particularly suitable in the welded pipe line that not can be removably mounted.
The present invention is achieved through the following technical solutions: formula Bivalved check valve, including valve body and valve deck are filled in one kind, it is described
Valve body offers a service hatch, and the cross sectional shape of the service hatch is rectangle；Covering on the service hatch has the valve deck；It is described
A connecting seat is provided in service hatch, the attachment base includes fixed disk and terminal pad, and the fixed disk and the terminal pad are
Integrated formed structure；The attachment base is fixed in the service hatch by the fixed disk by fastening nut；The terminal pad
Cross sectional shape be annulus；The attachment base offers flap fixation hole and valve rod fixation hole, the flap fixation hole and described
Valve rod fixation hole runs through the fixed disk and the terminal pad；The flap fixation hole is fixed with flap, the valve rod fixation hole
It is fixed with valve rod, is also connected with spring between the flap and the valve rod；A valve seat, institute are further fixedly arranged in the valve body
It states valve seat and the attachment base is to be flexible coupling.
Preferably, the fixed connection place of the valve seat and the valve body is sealed by a two-way spring energy-storage sealing ring.
Compared with prior art, effect is positive to the present invention:
1, the present invention is on the valve body of check-valves by opening up a rectangle service hatch, thus by associated components in valve body from
It is side-mounted to be changed to upper dress formula, facilitate the online installation and removal of valve inner correlated parts, in the welded pipe line that not can be removably mounted
In have good application value.
2, service hatch of the invention is designed as a rectangular configuration, and devises an attachment base for the rectangular configuration,
By the way that the connector in valve body other than valve seat to be each attached on attachment base, therefore when check-valves is safeguarded, will connect
Seat takes out and can repair outside valve body, and while installing also only needs first to install valve seat, is being packed into attachment base, greatly
The simple installation of check-valves is reduced greatly.

Specific embodiment
To make the above purposes, features and advantages of the invention more obvious and understandable, with reference to the accompanying drawing to the present invention
Specific embodiment be described in detail.
Detail is elaborated in the following description to fully understand the present invention.But the present invention can with it is a variety of not
Other way described herein is same as to implement, those skilled in the art can do class without violating the connotation of the present invention
Like popularization.Therefore the present invention is not limited by following public specific embodiment.
Embodiment one:
Referring to Fig. 1 to Fig. 4, upper dress formula Bivalved check valve, including valve body 1 and valve deck 2, valve body 1 offer a service hatch 3,
The cross sectional shape of service hatch 3 is rectangle；Service hatch 3 is sealed service hatch 3 by butt welding structure attaching nut with valve deck 2；Maintenance
Attachment base 4 is provided in hole 3, attachment base 4 includes fixed disk 41 and terminal pad 42, and fixed disk 41 and terminal pad 42 are integrally formed
Structure, cross sectional shape are T shape；Attachment base 4 is fixed in service hatch 3 by fixed disk 41 by fastening nut；Referring to fig. 4, even
The cross sectional shape for connecing disk 42 is annulus；Attachment base 42 offers flap fixation hole 43 and valve rod fixation hole 44, flap fixation hole 43
Run through fixed disk 41 and terminal pad 42 with valve rod fixation hole 44；Flap fixation hole 43 is fixed with flap 5, and valve rod fixation hole 55 is fixed
There is valve rod 6, spring 7 is also connected between flap 5 and valve rod 6；Valve seat 8, valve seat 8 and attachment base 4 are further fixedly arranged in valve body 1
To be flexible coupling.
Referring to Fig. 5, when on-line maintenance, valve deck is opened, attachment base is taken out, a component on attachment base can be tieed up
Shield, valve seat can also be removed easily and be safeguarded at this time；When terminating maintenance, installing on attachment base can be direct after each components
Attachment base is put into inside check-valves, i.e., inside installation is converted into external installation, degree flexible for installation is significantly improved, shortened
Assembly time；Also more side-mounted structure is more easily installed and safeguards upper dress formula structure simultaneously.
Embodiment two:
The present embodiment is that the another of embodiment one improves, and the fixed connection place of valve seat 8 and valve body 1 passes through a bidirectional spring
The sealing of accumulation of energy sealing ring.
Bidirectional spring accumulation of energy sealing ring provides longitudinal sealing in the conveying direction (transverse direction) of medium, when medium back flow,
Lateral sealing is then provided；To provide lasting elastic force, while it also can make up for it the gap generated in low temperature shrinkage.
Although the invention has been described by way of example and in terms of the preferred embodiments, but it is not for limiting the present invention, any this field
Technical staff without departing from the spirit and scope of the present invention, may be by the methods and technical content of the disclosure above to this hair
Bright technical solution makes possible variation and modification, therefore, anything that does not depart from the technical scheme of the invention, and according to the present invention
Technical spirit any simple modifications, equivalents, and modifications to the above embodiments, belong to technical solution of the present invention
Protection scope.
