One-way valve, is connecting pipeline or pipeline is contained in to the part on hydraulic element in hydraulic system, and this is a kind of general name of the link that can install and remove in fluid passage.
Sealing is to evaluate the important indicator of an one-way valve quality.At present, on market, the good one-way valve of sealing normally adopts thread type Placement to be connected with pipe fitting.
As disclosed a kind of multi-gear valve in Chinese invention patent prospectus 200810061841.8, belong to valve technology field.It has solved in existing single-pass ball valve and has existed the problem that degree of regulation is not high.This multi-gear valve comprises spool, valve rod and has water intake and the valve body of water outlet, spool is positioned at valve body, the inner of valve rod is connected with spool, the outer end of valve rod is stretched out valve body and is provided with handle, between valve rod and valve body, be provided with seal ring, on described spool, have several for being communicated with the water port of water intake and water outlet, the maximum water flowing aperture of above-mentioned each water port varies in size, and when valve is during in opening state, only there is one of them water port in being communicated with water intake and water outlet state.On the spool of this multi-gear valve, have the water port that several maximum water flowing apertures vary in size, user can freely select the water port of different gears to regulate, control flow.And while work in use water port, small aperture wherein, it is high that it also has degree of regulation, the advantage of easy-to-operat.
But, single-pass ball valve in above-mentioned patent, seal ring is to carry out extrusion expansion by hydraulic pressure, current in valve body are likely overflowed by the gap between seal ring and valve body in the time of crush seal circle, affect the sealing of valve body, and when water flow is less, current also cannot produce enough hydraulic pressure fully expands seal ring.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of single-pass ball valve that can improve by abundant crush seal circle valve seal for the above-mentioned state of the art.
For achieving the above object, the utility model provides following technological scheme:
A kind of single-pass ball valve, includes valve body, and valve body internal shaping has runner, offers the water intake and the water outlet that are connected with described runner on described valve body, on described water intake and described water outlet, is all sealedly connected with pipe joint, is socketed with water pipe on pipe joint,
It is characterized in that: described pipe joint comprises fixing part and active part, described fixing part one end is fixedly connected on described valve body, and the other end is opening end, and is provided with screw thread on described opening end, is connected with water pipe by described screw thread;
In described fixing part, offer chute, described active part one end is slidably connected in described fixing part by described chute, the other end protrude outside described fixing part and and the opening end of described fixing part between be formed with groove, in described groove, be fixed with seal ring;
On described valve body, offer through hole, on described through hole, being provided with can be by the flow switch of described through hole sealing, on described flow switch, be fixed with rotating shaft, described rotating shaft wore described through hole and extended in described valve body, was arranged with the block that can partly or entirely cut off described runner in described rotating shaft;
Described rotating shaft and described active part link by pinion and rack.
As preferably, in described rotating shaft, be arranged with gear, described active part is fixed with tooth bar wearing on the one end in fixing part, and described tooth bar engages to extending to described gear in described valve body.
As improvement, on the opening end of described fixing part, pad is provided with pad.
Compared with prior art, the utility model has the advantage of: the fixing part that the pipe joint on single-pass ball valve is arranged to mutually be slidably connected and active part, between active part and fixing part, be provided with groove, in groove, be embedded with seal ring, by the relative sliding between fixing part and active part, crush seal circle impels seal ring to be subject to compression swelling, fills the gap between full active part and fixing part; On valve body, be provided with flow switch, flow switch is controlled the relative sliding between active part and fixing part by pinion and rack, can cooperatively interact to the control of runner folding with flow switch, in the time that runner is closed, fixing part separates with active part, in the time that runner is opened, active part is to the close extruding of fixing part, can control this two kinds of actions by a flow switch simultaneously, more convenient.
