Description
[technical field]
The utility model is related to technical field of fluid delivery, specifically a kind of silk acting flange with check valve structure.
[background technology]
Check-valves is widely used in the water system for need non-return, and can play prevents outlet pipe from blowing back into water inlet pipe
Effect, can both completely cut off Inlet and outlet water, play health isolation effect, while being also a kind of protection to the pipeline before check-valves.
At present, existing check-valves typically uses independent structure, predominantly wafer type or flange form, and its connection is more bothered, and is expended
Material is more, is especially needing the place of screw thread and flange conversion, it is necessary to expend substantial amounts of manpower and materials.
[utility model content]
The purpose of this utility model seeks to solve above-mentioned deficiency and provide a kind of silk acting flange with check valve structure,
Both conversion connection can be carried out to screw thread and flange when needed, while built-in check valve, plays non-return and acts on, compact conformation,
Save labor.
A kind of silk acting flange with check valve structure, including hickey straight length 1, non-return are designed to achieve the above object
Valve pocket 2, flange 3, non-return valve core 4 and O-ring 5, the hickey straight length 1, check valve chamber 2, flange 3 are from left to right successively
Connection, the check valve chamber 2 is built-in with the non-return valve core 4 for preventing aqueous reflux, and the periphery of the non-return valve core 4 is arranged with O-shaped
Circle 5, is tightly connected by O-ring 5 between the non-return valve core 4 and check valve chamber 2 and is integrated.
The hickey straight length 1 in tubular construction, is provided with hickey, institute on the hickey straight length 1
State and flange-interface is provided with flange 3, the hickey straight length 1, flange 3 are used for flange-interface and screw thread in connection procedure
The conversion of interface.
The non-return valve core 4 is detachable to be installed in check valve chamber 2.
The right part of the non-return valve core 4 is built in inside flange 3.
The utility model is compared with the existing technology, there is provided the structure of a kind of screwed flange conversion, check-valves and one, uses
In the pipe-line system for needing non-return in flange threaded connection transfer process, this thread acting flange structure is novel, simple, and design is closed
Reason, both can carry out conversion connection to screw thread and flange when needed, while built-in check valve, plays non-return effect, structure is tight
Gather, save labor；Additionally, the silk acting flange with check valve structure described in the utility model, due to using built-in, installing more
Plus it is convenient, produce also relatively simple, it is worthy of popularization.
[brief description of the drawings]
Fig. 1 is structural representation of the present utility model；
In figure：1st, hickey straight length 2, check valve chamber 3, flange 4, non-return valve core 5, O-ring.
[specific embodiment]
Further explained below is made to the utility model below in conjunction with the accompanying drawings：
As shown in Figure 1, the utility model includes：Hickey straight length 1, check valve chamber 2, flange 3, non-return valve core 4
And O-ring 5, hickey straight length 1, check valve chamber 2, flange 3 be sequentially connected from left to right, check valve chamber 2 be built-in with for
The non-return valve core 4 of aqueous reflux is prevented, the periphery of non-return valve core 4 is arranged with O-ring 5, O is passed through between non-return valve core 4 and check valve chamber 2
Type circle 5 is tightly connected and is integrated.
Wherein, hickey straight length 1 in tubular construction, is provided with hickey, flange 3 on hickey straight length 1
On be provided with flange-interface, hickey straight length 1, flange 3 are used for the conversion of flange-interface and hickey in connection procedure；
Non-return valve core 4 is detachable to be installed in check valve chamber 2, and the right part of non-return valve core 4 is built in inside flange 3, plays non-return effect.
In the utility model, check valve chamber is used to place non-return valve core, and O-ring is used to fixing and sealing check valve chamber and stops
Return valve element, so this apparatus structure can be while crossover flange and hickey, you can with play connect in crossover flange
While the effect docked with screw thread, built-in check valve core plays a part of to prevent aqueous reflux.
Operation principle of the present utility model is：A check valve chamber is set up in the middle of flange and nipple joint, non-return valve core can
To be freely installed in check valve chamber, so as to play a part of non-return buffer fluid；Meanwhile, hickey straight length and flange can
To be conveniently used for the connection of fluid-transporting tubing side screw thread, a side flange.
The utility model is not limited by above-mentioned implementation method, other any real without departing from spirit of the present utility model
Matter and the change, modification, replacement made under principle, combine, simplify, should be equivalent substitute mode, being included in this practicality
Within new protection domain.
