Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, technological scheme of the present invention is further described.
As shown in Figure 1, a kind of overflow-type bilateral control valve case, include valve housing 1 and the mobile valve rod 5 that is arranged in the valve housing 1, described valve housing 1 is provided with import 2, described valve housing 1 top is provided with upper outlet 3, described valve housing 1 bottom is provided with down outlet 4, and described mobile valve rod 5 is provided with interlock valve plug 6 and the valve plug 7 that links down;
Wherein, described upper outlet 3 and the described 4 corresponding settings of outlet down, promptly satisfy: the center of the center of described upper outlet 3 and described outlet 4 down is on a vertical curve, so that upper and lower interlock valve plug seals it;
Described go up interlock valve plug 6 and the described valve plug of interlock down 7 respectively corresponding described upper outlets 3 and described outlet down 4 be provided with, and described go up between interlock valve plug 6 and the described valve plug 7 of interlock down distance less than described upper outlet 3 with described under export distance between 4; The described valve plug 6 that upward links satisfies interaction relation with the described valve plug 7 that links down: when the described valve plug 6 that upward links is arranged in the described upper outlet 3, export 4 under 7 disengagings of the described valve plug of interlock down are described and be provided with; When described down interlock valve plug 7 is arranged in the described outlet 4 down, the described interlock valve plug 6 of going up breaks away from described upper outlet 3 and is provided with; During work, described upper outlet 3 can not be sealed simultaneously with described outlet 4 down, can not be opened simultaneously; That is, during work, keep the two to have and only have one to be opened, and another is sealed;
Described valve housing 1 top is provided with filtrating equipment 8, and described filtrating equipment 8 corresponding described upper outlets 3 are provided with; Described filtrating equipment 8 is selected filter screen for use;
Described mobile valve rod 5 is bodys, and described mobile valve rod 5 tops are provided with overflow inlet 9, and described mobile valve rod 5 underparts are provided with overflow outlet 10, and described overflow inlet 9 is positioned at described filtrating equipment 8; Described overflow inlet 9 is communicated with described overflow outlet 10 by the body of described mobile valve rod 5, forms overflow ducts with this; Wherein, described overflow outlet 10 corresponding described outlets 4 down are provided with.
Export 4 down by 7 sealings of the described valve plug of interlock down when described, then described upper outlet 3 is opened, and middle water is gushed out from described upper outlet 3, stores after described filtrating equipment 8 filters; Water contains certain impurity in the cause, in case blocking up appears in 8 places at filtrating equipment, can't continue to enter Zhong Shui from described import 2, the various middle water drainage pipe that is described import 2 connections is blocked, and then cause whole middle water reclamation system or drain system fault, bring unnecessary trouble to people; Therefore, overflow ducts is set and will well stop this type of problem.
