Further, described spool upstream face boss outer surface is circular arc camber, or in the conical surface.
Further, described guide rod caves in described valve core cavity body direction.
Further, described guide rod cross section ovalize.
Further, described poppet shaft end is hemispherical.
Further, described guide sleeve inwall is a fastening plastic bushing also, and this plastic bushing end is exposed outside described guide sleeve.
Further, described spring is tapered, and the little head end of this spring is sheathed on plastic bushing, and this spring stub end contacts with the internal surface of described upstream face boss.
Further, the outward edge of described upstream face boss inlays a sealing gasket, and sealing pad and described upstream face boss outer surface smoother are excessive, in arc surface.
Further, described valve body and described guide cover joint are provided with a seal ring.
The utility model has the advantage of: the large runner of latus rectum is unobstructed, and resistance is little, good seal performance, during closedown, there is no water hammer and sound, suitable horizontal and vertical installation, the characteristics such as the life-span is long.And easy for installation, be convenient to maintain and replace.

Fig. 2 is that in the utility model, valve body and spool are the generalized section of closed condition.
Fig. 3 is that in the utility model, valve body and spool are the generalized section of full-gear.
Fig. 4 is sectional view of the present utility model.
Fig. 5 is the sectional view after the utility model flange is installed.
[embodiment]
Please refer to Fig. 1 to Fig. 5, the quiet sea cock and valve of flange-type, comprises in the valve body 1 of interior hollow, valve body 1 and has spool, and described spool comprises diversion face boss 21 and connected poppet shaft 22, described poppet shaft 22 is provided with guide sleeve 3, and described valve body 1 is by closely-pitched compact siro spinning technology one guide cover 4; Be connected by guide rod 5 between described guide sleeve 3 with described guide cover 4; Described poppet shaft 22 is arranged with spring 6, and described spring 6 is between described guide sleeve 3 and described upstream face boss 21; The inner chamber body surface 11 of described valve body 1 is overall in circular arc camber, to reduce hydraulic loss.Described valve body 1 upper end has bayonet socket 100 outwardly, facilitates flange-type to install, and described valve body 1 lower end has a horn mouth 101, and horn mouth 100 place is also provided with a filter screen 102.
The valve body 1 contacted with water, spool, water outlet side spool support adopt SUS304 stainless steel.
Described spool upstream face boss 21 outer surface 211 is in circular arc camber or in the conical surface, and poppet shaft 22 end 23, equally can to reduce hydraulic loss in hemispherical.
Described guide rod 5 caves in described valve body 1 inner chamber body direction, to increase the area of safety check inner chamber flow cross-section everywhere.
Described guide rod 5 cross section ovalize, oval length direction is arranged along water (flow) direction to reduce resistance.
Described guide sleeve 3 inwall is a fastening plastic bushing 7 also, and this plastic bushing 7 end is exposed outside described guide sleeve 3, has well main positive leading role to spool, and the not only suitable equally horizontal installation of suitable vertical installation, there will not be the mobile phenomenons that have some setbacks such as jam.
Described spring 6 is tapered, and the little head end of this spring 6 is sheathed on plastic bushing 7, and this spring 6 stub end contacts with the internal surface of described upstream face boss 22.During spool 2 standard-sized sheet, volute spring 6 is compressed into one and is similar to closely knit taper, can effectively prevent current from perturbing, favourable minimizing current loss.
The outward edge of described upstream face boss 21 inlays a sealing gasket 212, and sealing pad 212 is excessive with described upstream face boss 21 outer surface smoother, in arc surface.Sealing gasket 212 closely cooperates with water surface boss 21 outer surface conical surface or arc surface and seamlessly transits, water outlet edge presents circular arc, to reduce hydraulic loss, sealing gasket 212 circumferential perimeter is identical with upstream face boss 21 external diameter, makes sealing gasket 212 and upstream face boss 21 form one.
Described valve body 1 is provided with an O RunddichtringO 8 with described guide cover 4 joint.The same end face that guide cover 4 and valve body 1 can keep two parts to form after locking is smooth, the sealing of water outlet end face when installing in order to safety check, valve body 1 is connected fastening with guide cover 4 by closely-pitched, and ensures two member lumens flow surface joint smooth and seamless gaps or step.
Check valve adopts and connects folder mode, allows vertical and horizontal installation.
Safety check and flange contact facings establish multiple-sealed water stop slot.
The large runner of the utility model latus rectum is unobstructed, and resistance is little, good seal performance, does not have water hammer and sound, non-corrosive during closedown, suitable horizontal and vertical installation, the characteristics such as the life-span is long.And easy for installation, be convenient to maintain and replace.
