By adopting technique scheme, be connected with the mounting groove on valve body by spacing section, central siphon is realized to the effect of location, through hole is made just to be in same plane with water port, when wanting water flowing, slided in inner core section by rotary valve rod band movable valve plug, make spool higher than through hole, make through hole and water port conducting.When cutting off the water supply being, being slided, make spool lower than through hole, make spool block water intake by rotary valve rod band movable valve plug in inner core section, water just can not flow in flow channel.
The utility model is set to further: described movable joint comprises interconnective limit body and positioning body, and positioning body outer wall offers some positioning steps, the diameter of limit body and the equal diameters of clamping cap.
By adopting technique scheme, movable joint is for connecting other pipe fittings, during installation, movable joint is inserted in the cylindrical shell of location, limit body is conflicted on the second seal ring, again by clamping cap is threaded with location cylinder, make to contact with limit body, realize the installation to movable joint.
Accompanying drawing explanation
Fig. 1 is structure sectional view of the present utility model.
Embodiment
With reference to Fig. 1, embodiment of the present utility model is described further.
A kind of dog valve, comprising valve body 1, running through the central siphon 2 of valve body 1 and the locking cap 3 for connecting central siphon 2, also union has been stretched in valve body 1, movable joint 4 is removably connected by clamping cap 5 and valve body 1, be connected with spool 6 in central siphon 2, between central siphon 2 and movable joint 4, be provided with flow channel, in central siphon 2, be provided with water intake 200, locking cap 3 offers the construction opening 30 of corresponding spool 6, this construction opening 30 is removably connected with blocking cap 31.
After central siphon 2 passes from valve body 1, the partial threads stretched out with central siphon 2 by locking cap 3 is connected, and then fixing central siphon 2 does not skid off from valve body 1, when needs make flow channel circulate, by blocking cap 31 under construction opening 30 dismounting, valve rod to be stretched in central siphon 2 from construction opening 30 and is connected with spool 6, realizing the rotation to spool 6, and then control the lifting of spool 6.This structure adopts the mode of the autonomous installing/dismounting of valve rod, ensure that the performance of the self-locking of this product, if do not have valve rod just can not use this product, has stopped accident and has opened valve and cause the situation with current mistake.
When needing dismounting, locking cap 3 is back-outed from central siphon 2, central siphon 2 can be extracted out in valve body 1, in like manner, as long as clamping cap 5 is back-outed from valve body 1, just movable joint 4 can be extracted out, substantially increase the efficiency of installing/dismounting.
The setting of blocking cap 31, prevents foreign object from falling in central siphon 2 and affect water outlet efficiency or pollute central siphon 2.
Valve body 1 comprises mounting cylinder 11 body for installing central siphon 2 and location cylinder 12 body for installing movable joint 4, mounting cylinder 11 body and location cylinder 12 body are interconnected, mounting cylinder 11 offers inlet 10 with the joint of location cylinder 12, the two ends of mounting cylinder 11 body offer mounting groove respectively, the bottom land of mounting groove is provided with annular protrusion 110, is provided with the first sealed loop-pad 2a in mounting groove; The inwall of described location cylinder 12 is provided with internal thread, and is provided with the second sealed loop-pad 2b in location cylinder 12, and the thickness of the second sealed loop-pad 2b is greater than the first sealed loop-pad 2a.
The setting of mounting groove is for while installing sealed loop-pad, serve the limit effect to locking cap 3 and central siphon 2, the setting of the first seal ring ensure that locking cap 3 follows the sealing of the contact of valve body 1 and central siphon 2 to follow the sealing of valve body 1 contact, has stopped by water spill valve 1.
The setting of the annular protrusion 110 on mounting groove, due to the first sealed loop-pad 2a employing is that rubber is made, there is elasticity, therefore push up on the first seal ring by annular protrusion 110, make the first seal ring depression, substantially increase sealing effect, and the first seal ring can be facilitated to remove in mounting groove.The setting of the second sealed loop-pad 2b substantially increases the sealability of movable joint 4 and valve body 1.
