Abstract
The utility model provides a kind of upper dress formula Bivalved check valve, and comprise valve body and valve gap, valve body offers service hatch, and the sectional shape of service hatch is rectangle; Service hatch adds and is stamped valve gap; Be provided with connecting base in service hatch, connecting base comprises fixed tray and land, and fixed tray and land are formed in one structure; The sectional shape of land is annulus; Connecting base offers flap fixed hole and valve rod fixed hole, and flap fixed hole is fixed with flap, and valve rod fixed hole is fixed with valve rod, is also connected with spring between flap and valve rod; Also be fixedly installed valve seat in valve body, valve seat and connecting base are for being flexible coupling.The utility model by offering a rectangle service hatch on the valve body of safety check, thus changed associated components in valve body into upper dress formula from side-mounted, facilitate the online installation and removal of valve inner correlated parts, good using value can not be had in the welded pipe line of dismounting.
Description
Technical field
The utility model belongs to field of check valves, relates to the on-line maintenance technology of safety check, specifically a kind of upper dress formula Bivalved check valve.
Background technique
Double-disc type check valve is a kind of automatic valve relying on pressure medium to open and close, now domesticly mainly adopt side-mounted structure when installing Double-disc type check valve, therefore when the Double-disc type check valve on pipeline needs to safeguard, must pull down from pipeline, for the Double-disc type check valve be welded on pipeline, this maintenance mode is loaded down with trivial details, and has larger impact to pipeline and production process, can not realize on-line maintenance.
Model utility content
The purpose of this utility model is to provide a kind of upper dress formula Bivalved check valve, makes bivalve Bivalved check valve to realize on-line maintenance, namely need not pull down from pipeline and just can carry out corresponding maintenance work, and being particularly useful for can not in the welded pipe line of dismounting.
The utility model is achieved through the following technical solutions: dress formula Bivalved check valve in one, and comprise valve body and valve gap, described valve body offers a service hatch, and the sectional shape of described service hatch is rectangle; Described service hatch has added a cover described valve gap; Be provided with a connecting seat in described service hatch, described connecting base comprises fixed tray and land, and described fixed tray and described land are formed in one structure; Described connecting base is fixed in described service hatch by tightening nut by described fixed tray; The sectional shape of described land is annulus; Described connecting base offers flap fixed hole and valve rod fixed hole, and described flap fixed hole and described valve rod fixed hole run through described fixed tray and described land; Described flap fixed hole is fixed with flap, and described valve rod fixed hole is fixed with valve rod, is also connected with spring between described flap and described valve rod; Also be fixedly installed a valve seat in described valve body, described valve seat and described connecting base are for being flexible coupling.
Preferably, the fixed connection place of described valve seat and described valve body is sealed by a two-way spring energy-storage seal ring.
Compared with prior art, its effect is positive to the utility model:
1, the utility model by offering a rectangle service hatch on the valve body of safety check, thus changed associated components in valve body into upper dress formula from side-mounted, facilitate the online installation and removal of valve inner correlated parts, good using value can not be had in the welded pipe line of dismounting.
2, service hatch of the present utility model is designed to a rectangular configuration, and devise a connecting base for this rectangular configuration, by the link in valve body except valve seat is all fixed on connecting base, therefore when safety check is safeguarded, connecting base is taken out and can keep in repair in valve body outside, and also only need when installing first valve seat to be installed, at loading connecting base, greatly reduce the simple installation of safety check.

Embodiment
For enabling above-mentioned purpose of the present utility model, feature and advantage more become apparent, and are described in detail embodiment of the present utility model below in conjunction with accompanying drawing.
Set forth detail in the following description so that fully understand the utility model.But the utility model can be different from alternate manner described here to implement with multiple, those skilled in the art can when doing similar popularization without prejudice to when the utility model intension.Therefore the utility model is not by the restriction of following public embodiment.
Mode of execution one:
See Fig. 1 to Fig. 4, upper dress formula Bivalved check valve, comprises valve body 1 and valve gap 2, and valve body 1 offers a service hatch 3, and the sectional shape of service hatch 3 is rectangle; Service hatch 3 is sealed by butt welding structure attaching nut by service hatch 3 and valve gap 2; Be provided with connecting base 4 in service hatch 3, connecting base 4 comprises fixed tray 41 and land 42, and fixed tray 41 and land 42 are formed in one structure, and its sectional shape is T-shaped; Connecting base 4 is fixed in service hatch 3 by tightening nut by fixed tray 41; See Fig. 4, the sectional shape of land 42 is annulus; Connecting base 42 offers flap fixed hole 43 and valve rod fixed hole 44, and flap fixed hole 43 and valve rod fixed hole 44 run through fixed tray 41 and land 42; Flap fixed hole 43 is fixed with flap 5, and valve rod fixed hole 55 is fixed with valve rod 6, is also connected with spring 7 between flap 5 and valve rod 6; Also be fixedly installed valve seat 8 in valve body 1, valve seat 8 and connecting base 4 are for being flexible coupling.
See Fig. 5, during on-line maintenance, open valve gap, fech connection seat, can safeguard the individual assembly on connecting base, now valve seat also can be removed easily and safeguard; When terminating to safeguard, directly connecting base can be put into safety check inside after connecting base installs each component, be about to inner installation and be converted to outside installation, degree flexible for installation significantly improves, and shortens installation time; Go up the dress formula structure also easier I&M of more side-mounted structure simultaneously.
Mode of execution two:
The present embodiment is that the another kind of embodiment one improves, and valve seat 8 is sealed by a two-way spring energy-storage seal ring with the fixed connection place of valve body 1.
Bidirectional spring accumulation of energy seal ring provides longitudinal sealing at the throughput direction (transverse direction) of medium, when medium back flow, then provides horizontal sealing; Thus lasting elastic force is provided, also can make up the gap produced when low temperature shrinkage simultaneously.
Although the utility model with preferred embodiment openly as above; but it is not for limiting the utility model; any those skilled in the art are not departing from spirit and scope of the present utility model; the Method and Technology content of above-mentioned announcement can be utilized to make possible variation and amendment to technical solutions of the utility model; therefore; every content not departing from technical solutions of the utility model; the any simple modification done above embodiment according to technical spirit of the present utility model, equivalent variations and modification, all belong to the protection domain of technical solutions of the utility model.
