Abstract
The invention discloses a kind of pipe connecting devices, including attachment device main body, the attachment device main body is hubbed flange attachment device, the attachment device main body includes ring flange and neck tube tail, several bolts hole are offered on the ring flange, the neck tube tail of the attachment device main body is by being provided with safety groove on one end of ring flange, the neck tube tail of the attachment device main body is smooth tube tail, and the attachment device main body is cast for integral type.Several described bolts hole claim arrangement to set in pairs, and the distance between several described bolts hole are equal.Hubbed flange attachment device of the present invention for integral type casting, good airproof performance will not occur leakage phenomenon, and directly can carry out abutting joint with rubber hose, without other crossover connection tails.
Description
Technical field
The present invention relates to pipe fittings to connect accessory technical field, specifically, being to be related to a kind of pipe connecting device.
Background technology
At present, in hydraulic system, quick coupling is needed to be sealed anti-leak, flanged joint is the one of quick coupling
Kind, flanged joint is exactly two pipelines, pipe fitting or equipment, is first individually fixed on a ring flange, then in two flanges
Plus flange gasket between disk, finally its one kind combined closely is made removably to connect two ring flange tensions with bolt
Head.Bump joint on the market at present, poor sealing easily occur fluid leakage, and cannot directly be docked with rubber hose
Installation needs to carry out abutting joint by other crossover connection tails.
Therefore, in the prior art, poor sealing easily occurs fluid leakage, and cannot directly be carried out with rubber hose pair
The problems such as connecing installation, needing to carry out abutting joint by other crossover connection tails, designs a kind of pipe connecting device, is to need at present
Technical problems to be solved.
Invention content
Goal of the invention：It is in view of the drawbacks of the prior art and insufficient, poor sealing is solved, fluid leakage easily occurs, and cannot
The problems such as directly carrying out abutting joint with rubber hose, needing to carry out abutting joint by other crossover connection tails, applicant's warp
It crosses repeatedly practice to improve, devises a kind of pipe connecting device.
Technical solution：In order to achieve the above-mentioned object of the invention, a kind of pipe connecting device, it is described including attachment device main body
Attachment device main body is hubbed flange attachment device, and the attachment device main body includes ring flange and neck tube tail, the flange
Several bolts hole are offered on disk, the neck tube tail of the attachment device main body on one end of ring flange by being provided with safety
Slot, the neck tube tail of the attachment device main body is smooth tube tail, and the attachment device main body is cast for integral type.
Several described bolts hole claim arrangement to set in pairs, and the distance between several described bolts hole are equal.
Advantageous effect：Compared with prior art, the present invention advantage is：
Leakage phenomenon will not occur for hubbed flange attachment device of the present invention for integral type casting, good airproof performance, and directly
Abutting joint can be carried out with rubber hose, without other crossover connection tails.
Description of the drawings
Fig. 1 is a kind of structure diagram of pipe connecting device.
In figure：1st, attachment device main body；2nd, safety groove.
Specific embodiment
Below by a most preferred embodiment, the technical program is described in detail, but protection scope of the present invention
It is not limited to the embodiment.
As shown in Figure 1, a kind of pipe connecting device, including attachment device main body 1, the attachment device main body 1 is band neck
Flange connecting apparatus, the attachment device main body 1 include ring flange and neck tube tail, several spiral shells are offered on the ring flange
Keyhole, the neck tube tail of the attachment device main body 1 on one end of ring flange by being provided with safety groove 2, the attachment device master
The neck tube tail of body 1 is smooth tube tail, and the attachment device main body 1 is cast for integral type.
Several described bolts hole claim arrangement to set in pairs, and the distance between several described bolts hole are equal.
The above is only the preferred embodiment of the present invention, it should be pointed out that：For the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications also should
It is considered as protection scope of the present invention.
