Abstract
The utility model relates to a stop valve of a water supply pipeline, which comprises a valve body, a valve seat, a valve cover arranged on the valve seat, a valve rod, a hand wheel and a valve clack, wherein the valve seat is fixedly connected with the valve body, the valve rod is tightly penetrated at the valve seat, one end of the valve rod is fixedly connected with the hand wheel, the other end of the valve rod is connected with the valve clack, an inlet flow passage, a first outlet flow passage and a second outlet flow passage are arranged in the valve body, the inlet flow passage and the first outlet flow passage take a first valve orifice as a boundary, the inlet flow passage and the second outlet flow passage take a second valve orifice as a boundary, the second valve orifice and the first valve orifice are arranged in parallel, and the valve clack is positioned in a space formed by the first valve orifice and the second valve orifice. The utility model has the advantages that the water supply operation of the pipeline can be uninterruptedly carried out, and even the normal water supply of the pipeline still can be ensured under the condition that one branch pipeline of the pipeline needs to be maintained.
Description
[technical field]
The utility model relates to a kind of stop valve, relates in particular to a kind of feedwater piping stop valve.
[background technique]
See also Fig. 1, at present the pipe break valve of feedwater usefulness generally comprises the flap 6 ' that valve body 1 ', valve gap 2 ', valve seat 3 ', valve rod 4 ', handwheel 5 ' and are positioned at valve body 1 ', valve seat 3 ' is fixedlyed connected with valve body 1 ', valve rod 4 ' closely is arranged in valve seat 3 ', and an end of valve rod 4 ' is fixedlyed connected with handwheel 5 ', the other end is connected with flap 6 ', offer an inlet channel 11 ' and an outlet flow 12 ' in this valve body 1 ', and this two runners, one lobe mouth 13 ' is the boundary, in addition, valve gap 2 ' is to be used to tighten up valve rod 4 '.When rotating counterclockwise handwheel 5 ', valve rod 4 ' drives flap 6 ' and moves toward the direction away from lobe mouth 13 ', and current just enter outlet flow 12 ' from inlet channel 11 ' via lobe mouth 13 ', thereby make the whole pipe water outlet; When clockwise rotating handwheel 5 ', valve rod 4 ' drives flap 6 ' gradually near lobe mouth 13 ', and when flap 6 ' was sealed lobe mouth 13 ' fully, then current can't flow into outlet flow 12 '.The stop valve of this spline structure makes the current can't flow ipe need clockwise rotating handwheel 5 ' when keeping in repair to the pipeline of end not; When if two branch feedwater pipings are arranged then need to install 2 this stop valves, both increased construction cost and also improved difficulty of construction; If a stop valve is installed on house steward, then wherein during a lateral, will close main valve in maintenance, cause another pipeline to cut off the water supply, influence the normal water supply operation.
[model utility content]
Technical problem to be solved in the utility model is to provide a kind of feedwater piping stop valve, can make the unremitting operation of feeding water of pipeline, even under the situation that a lateral need keep in repair therein, still can guarantee the normal water supply of pipeline.
The utility model solves the problems of the technologies described above by the following technical programs: a kind of feedwater piping stop valve, comprise a valve body, one valve seat, one is located at the valve gap on the valve seat, one valve rod, one handwheel and a flap, described valve seat is fixedlyed connected with valve body, described valve rod closely is arranged in valve seat, and an end of this valve rod is fixedlyed connected with handwheel, the other end is connected with flap, be provided with an inlet channel in the described valve body, one first outlet flow and one second outlet flow, the described inlet channel and first outlet flow are the boundary with one first lobe mouth, the described inlet channel and second outlet flow are the boundary with one second lobe mouth, this the second lobe mouth and the first lobe mouth be arranged in parallel, and described flap is positioned at the space of the first lobe mouth and the second lobe interruption-forming.
The beneficial effect of a kind of feedwater piping stop valve of the utility model is: by set up one second outlet flow in valve body, and second lobe mouth of this second outlet flow and inlet channel boundary and the existing first lobe mouth be arranged in parallel, thereby all can guaranteeing pipeline, the arbitrary position that makes flap be positioned at the first lobe mouth and the second lobe interruption-forming space have water to flow into, even when wherein a lateral needs repairing, only need flap is sealed an its corresponding lobe mouth, and do not influence the feedwater operation of another lateral.
[description of drawings]
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the sectional view of existing feedwater piping stop valve.
Fig. 2 is one of sectional view of a kind of feedwater piping stop valve of the utility model.
Fig. 3 be a kind of feedwater piping stop valve of the utility model sectional view two.
[embodiment]
Please in conjunction with consulting Fig. 2 and Fig. 3, a kind of feedwater piping stop valve of the utility model, comprise a valve body 1, one valve seat 2, one is located at the valve gap 3 on the valve seat 2, one valve rod 4, one handwheel 5 and a flap 6, described valve seat 2 is fixedlyed connected with valve body 1, described valve rod 4 closely is arranged in valve seat 2, and an end of this valve rod 4 is fixedlyed connected with handwheel 5, the other end is connected with flap 6, be provided with an inlet channel 11 in the described valve body 1, one first outlet flow 12 and one second outlet flow 13, the described inlet channel 11 and first outlet flow 12 are the boundary with one first lobe mouth 14, the described inlet channel 11 and second outlet flow 13 are the boundary with one second lobe mouth 15, this the second lobe mouth 15 and the first lobe mouth 14 be arranged in parallel, and described flap 6 is positioned at the space of the first lobe mouth and the second lobe interruption-forming.In addition, first outlet flow 12 and one second outlet flow 13 in the utility model can be arranged in parallel (as shown in Figure 2), also vertical setting (as shown in Figure 3) mutually.
The utility model makes flap 6 come downwards to the second lobe mouth 15 and when it seal, then the current of inlet channel 11 only via the first lobe mouth, 14 inflows, first outlet flow 12, promptly had only 12 water outlets of first outlet flow when rotating handwheel 5 in application process; When rotation handwheel 5 makes flap 6 occupy between the first lobe mouth 14 and the second lobe mouth 15, then the current of inlet channel 11 not only flow into first outlet flow 12 via the first lobe mouth 14, and via the second lobe mouth, 15 inflows, second outlet flow 13, but i.e. first outlet flow 12 and the 13 equal water outlets of second outlet flow; Make flap 6 go upward to the first lobe mouth 14 and when it seal, then the current of inlet channel 11 only via the second lobe mouth, 15 inflows, second outlet flow 13, promptly had only 13 water outlets of second outlet flow when rotating handwheel 5.When practical operation, when wherein a lateral needs repairing, only need flap 6 is sealed its corresponding lobe mouth, and do not influence the feedwater operation of another lateral, and then guarantee that pipeline can unremitting normal water supply.
