Abstract
The utility model discloses an all-welded automatic flushing and filtering ball valve. The all-welded automatic 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 flushing and filtering ball valve further comprises a filtering screen (6) placed in the ball body (3), and the filtering screen (6) is connected with the left end of the ball body (3). By means of the all-welded automatic flushing and filtering ball valve, the ball body (3) is connected with the feeding channel (4), the filtering screen (6) is arranged at one end of the ball body (3), and therefore when water enters 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 ball body (3), 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 auto-flushing Filtering 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 auto-flushing Filtering 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 auto-flushing Filtering 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 spheroid 3; Described filter screen 6 is connected with spheroid 3 left ends.
Further, on described valve body 2, offer sewage draining exit 7, described sewage draining exit 7 is connected with drain pipe 10 one end, and described drain pipe 10 the other ends connect blowdown valve 8.
Further, described Filtering ball valve arranged outside has cleaning hose 9; Described cleaning hose 9 one end are connected with downside or the side tube wall of crossing feeding-passage 4, and the other end is connected with valve body 2 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 feeding-passage 4 one end filter screen 6 is set, when water enters spheroid 3 when interior, filter screen is realized the impurity in interception water, the function of foreign matter, because filter screen is mounted in spheroid 3 inside, saved installing space, do not need to increase new ball valve, save cost of production, and reduced leak source.
Accompanying drawing explanation
