The outer wall of left body is connected with middle cylinder left end and left body end face opening is positioned at middle cylinder；Described right flange connections includes each other
The right flange being connected and right body, described right body is connected with middle cylinder right-hand member；Described right end face of flange is provided with removable spool
Positioning sleeve, described spool is positioned at middle cylinder, and described spool includes valve rod and flap, and described valve rod can do the most sliding at positioning sleeve
Dynamic, described flap contacts with the end face opening of left body sealing；It is provided with return spring between described spool and positioning sleeve.
In said structure, left flange connections is connected with middle cylinder by the way of welding with right flange connections, left flange
All being connected by the way of welding with right body with left body and right flange, this structure can be greatly reduced valve body cast-in-block
Casting cost, overall weight is light, can be prevented effectively from the stress concentration caused because volume is excessive and make the problems such as valve body craze and transfiguration,
Can be processed being assemblied together again to each parts during production, be prevented effectively from because of operation mistake a certain when monoblock type valve body is processed
The phenomenon causing whole valve body to be scrapped occurs.
This utility model is further arranged to, and described spool positioning sleeve includes gripper shoe and is positioned at the cunning at support plate center
Cylinder, described gripper shoe is arranged in the end face of right flange, and the end face of described gripper shoe is concordant with right end face of flange.
This utility model is further arranged to, and described slide cartridge is arranged at gripper shoe towards on a side end face of right body, institute
State valve rod and be positioned at slide cartridge slip.
In said structure, valve rod can be done constraint by slide cartridge makes the valve rod can only be along the axial direction of valve body on spool positioning sleeve
Sliding, radially enabling capabilities is strong, and when making flap close, flap and left body are positioned at the sealing position that the end face holding of middle cylinder is correct
Put, it is to avoid occur that the phenomenons such as sealing surface dislocation cause leakage, thus service life is greatly improved, the most non-maintaining.
This utility model is further arranged to, and described middle cylinder is cydariform.
In said structure, in cydariform, cylinder can increase flow section, compensates with this and is positioned at middle cylinder flap to valve body stream
The impact that dynamic sectional area produces.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Below
Embodiment is used for illustrating this utility model, but is not limited to scope of the present utility model.
With reference to Fig. 1, a kind of integral type maintenance-free check-valves as shown in Figure 1, including valve body 10 and be arranged at valve body
Spool 20 in 10, described valve body 10 includes left flange connections 11, right flange connections 12 and middle cylinder 13, described middle cylinder 13 with
Left flange connections 11 and right flange connections 12 are connected；Described left flange connections 11 includes the left flange 111 being connected with each other
And left body 112, during the outer wall of described left body 112 is connected with the left end of middle cylinder 13 and the end face opening of left body 112 is positioned at
