Abstract
The utility model discloses an all-welded automatic back-flushing and filtering ball valve. The all-welded automatic back-flushing and filtering ball valve comprises a valve rod (1), a valve body (2) and a ball body (3), wherein the ball body (3) is placed in the valve body (2) and connected with the lower end of the valve rod (1), the left end of the ball body (3) is connected with a feeding channel (4), and the right end of the ball body (3) is connected with a discharging channel (5). The all-welded automatic back-flushing and filtering ball valve further comprises a filtering screen (6) placed in the discharging channel (5), and the filtering screen (6) is connected with the right end of the ball body (3). By means of the all-welded automatic back-flushing and filtering ball valve, the ball body (3) is connected with the discharging channel (5), the filtering screen (6) is arranged at one end of the ball body (3), and therefore when water flows through the ball body (3), the filtering screen achieves the function of blocking impurities and foreign matter in the water; because the filtering screen is arranged inside the discharging channel (5), installation space is saved, no new ball valve needs to be added, production cost is saved, and the number of leakage points is reduced.
Description
Technical field
The utility model relates to ball valve field, in particular to a kind of full welding automatic back flush filtration ball valve.
Background technique
In urban heating system, adopt heat supply unit-pipe network---user model more, wherein heat supply unit is the source of thermal energy exchange and circulation.In heat supply set, except configuration heat exchanger, recycle pump, outside pipe network temperature, pressure and flow regulator, also installs a lot of welding ball valves with pilot line fluid (working medium).Because pipeline network construction regulates institute to limit, pipe cleanness is poor, and various metals or non-metal foreign body are more, if impurity foreign matter is irregularly clear in time, will have a strong impact on the safety reliability of pipe network equipment life-span and pipe network operation.Therefore it is essential, on heat supply unit, adding fixed filter.
But, while removing in pipe network impurity foreign matter by conventional filter, must welding ball valve be installed at filter two ends, cause cost of production significantly to increase, and it is large to take up room, leak source increases.
For clearing up by filter in prior art, impurity foreign matter cost of production in pipe network is high, the problems large, that leak source is many that take up room, and not yet proposes at present effective solution.
Model utility content
For clearing up by filter in prior art, in pipe network, impurity foreign matter cost of production is high, problems large, that leak source is many take up room, effective solution is not yet proposed at present, effective solution is not yet proposed at present, for this reason, main purpose of the present utility model is to provide a kind of full welding automatic back flush filtration ball valve, to address the above problem.
To achieve these goals, according to an aspect of the present utility model, a kind of full welding automatic back flush filtration ball valve is provided, comprise valve rod 1, valve body 2, spheroid 3, described spheroid 3 is placed in valve body 2 and is connected with valve rod 1 lower end, described spheroid 3 left ends connect feeding-passage 4, and right-hand member connects tapping channel 5, and described Filtering ball valve also comprises the filter screen 6 being placed in tapping channel 5; Described filter screen 6 is connected with spheroid 3 right-hand members.
Further, described filter screen 6 downsides offer sewage draining exit 7, and described sewage draining exit 7 is connected with drain pipe 10 upper ends, and the downside tube wall of tapping channel 5 is passed in described drain pipe 10 lower ends, and connects blowdown valve 8.
Further, described Filtering ball valve arranged outside has backwash tube 9; Described backwash tube 9 one end are connected with feeding-passage 4 downsides or side tube wall, and the other end is connected with tapping channel 5 upsides or side tube wall.
Further, described filter screen 6 is stainless steel taper filter screens 6.
Further, described Filtering ball valve is integrated all-welded ball valve.
Pass through the utility model, at spheroid 3, connect tapping channel 5 one end filter screen 6 is set, when water is when flowing through in ball for ball valve 3, filter screen is realized the impurity in interception water, the function of foreign matter, because filter screen is mounted in tapping channel 5 inside, saved installing space, do not need to increase new ball valve, save cost of production, and reduced leak source.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms the application's a part, and schematic description and description of the present utility model is used for explaining the utility model, does not form improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is according to the cross-sectional view of the utility model embodiment's full welding automatic back flush filtration ball valve;
Fig. 2 is according to the first structural representation of the utility model embodiment's full welding automatic back flush filtration ball valve;
Fig. 3 is according to the second structural representation of the utility model embodiment's full welding automatic back flush filtration ball valve.
Embodiment
It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the application can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
Fig. 1 is according to the cross-sectional view of the utility model embodiment's full welding automatic back flush filtration ball valve; As shown in Figure 1, full welding automatic back flush filtration ball valve, comprise valve rod 1, valve body 2, spheroid 3, described spheroid 3 is placed in valve body 2 and is connected with valve rod 1 lower end, described spheroid 3 left ends connect feeding-passage 4, right-hand member connects tapping channel 5, and described Filtering ball valve also comprises the filter screen 6 being placed in tapping channel 5; Described filter screen 6 is connected with spheroid 3 right-hand members.Described filter screen 6 can be connected with spheroid 3 right-hand members by bolt and/or interior jump ring, also can be connected with spheroid 3 right-hand members by welding manner.
Pass through the utility model, at spheroid 3, connect tapping channel 5 one end filter screen 6 is set, when water is when flowing through in ball for ball valve 3, filter screen is realized the impurity in interception water, the function of foreign matter, because filter screen is mounted in tapping channel 5 inside, saved installing space, do not need to increase new ball valve, save cost of production, and reduced leak source.
