Abstract
The utility model relates to an automatic control regulator used for automatically controlling and regulating liquid flow in a water tank. The middle part of a valve cavity is provided with a table shoulder, and a ball valve is movably arranged in a guiding ring. The lower part is provided with a push rod movably contacted with an eccentric cam. A floating body drives the eccentric cam to rotate in anticlockwise or clockwise directions to enable the push rod to push the ball valve for automatically controlling water inlet flow. The automatic control regulator has the advantages of simple structure and stable operation.
Description
The utility model relates to the modulating valve of water (liquid liquid) face of regulating control water inlet (liquid) pond, specifically is a kind of from control regulation valve.
Being used for the device of water tank or tank for excrement pan water inlet control at present, generally is to use float valve, and it adopts lever roof pressure valve core, is in work (roof pressure) state for a long time, influences working life, and the ball float volume is big simultaneously, and length of connecting rod breaks down easily.
The utility model designs a kind of compact structure, utilize water (liquid) self pressure closes valve door from control regulation valve.
The utility model realizes that the technological scheme of above-mentioned purpose is described below: it includes valve body, ball valve, guide ring, push rod, eccentric cam and buoyancy aid, there is shoulder intermediate portion at valve pocket, the shoulder upper end is provided with guide ring, the guide ring inner chamber is joined and is put ball valve, valve pocket is provided with push rod below the shoulder, its technical characterstic is that buoyancy aid connects eccentric cam by sleeve pipe, and one of push rod lower end contacts with eccentric cam is movable.
Because buoyancy aid of the present utility model rises or descends with water (liquid) face change in location, drive eccentric cam and sway, drive the upper and lower roof pressure ball valve of push rod, upper and lower realization is closed or is opened, and controls the height of water (liquid) face automatically.Guide pad and guide ring can make push rod and the directed operation of ball valve, have compact structure than float valve, and push rod and ball valve are stable, reduce rate of breakdown.
Below, press description of drawings and embodiment's description, details are as follows to technology contents of the present utility model:
Fig. 1 is the utility model topology view.
The utility model from the control regulation valve structure as shown in Figure 1, the valve pocket middle part of valve body 4 is equipped with shoulder 3, the top of shoulder 3 is placed with movable guide ring 6, the inner chamber of guide ring 6 has and is disjunct 4 muscles and bones of corresponding cross, the centre is the hole, garden, ball valve 5 activities are placed in the hole, middle garden of 4 muscles and bones, ball valve 5 with the variation in pressure of water along the oscilaltion of hole, garden.The movable push rod 7 that is connected as a single entity with guide pad of placing in the valve pocket of shoulder 3 belows, it is spherical that push rod 7 lower ends are the garden, with eccentric cam 8 movable contacts, buoyancy aid 1 one ends are threaded with the sleeve pipe 2 that the rotating shaft 9 that links to each other with valve body 4 is connected, between sleeve pipe 2 and valve body 4 openings certain interval is arranged, buoyancy aid 1 inner chamber is equipped with whole inner chamber 2/3rds or 3/4ths water (liquid), keeps and water (liquid) equal specific gravity.Buoyancy aid 1 is in the liquid level, and when water (liquid) face decline certain altitude, buoyancy aid 1 descends, rotate 8 inverse time of eccentric cam with driving around rotating shaft 9 by sleeve pipe 2, pushing tow push rod 7 and guide pad rise, one of the upper end of push rod 7 ball valve 5 of appearing on the stage, and ball valve 5 is along rising water inlet (liquid) on the hole, garden in the guide ring 6; At liquid level rising certain altitude, buoyancy aid 1 makes the rotation of eccentric cam 8 up times again, and push rod 7 descends along eccentric cam 8 peripheries, and ball valve 5 descends along hole, middle garden under the effect of water (liquid) pressure, stops up the center hole of shoulder 3, hermetically closing water (liquid) flow.
Claims (2)
1, a kind of from control regulation valve, it includes valve body, guide ring, ball valve, push rod, there are shoulder, cavity of resorption that the push rod that is connected as a single entity with guide pad is arranged in the middle of eccentric cam and the buoyancy aid, valve pocket, epicoele has guide ring, put ball valve in the guide ring, it is characterized in that buoyancy aid (1) links to each other with eccentric cam (8), eccentric cam (8) contacts with push rod (7) is movable.
2, according to claim 1 from control regulation valve, it is characterized in that being placed with in buoyancy aid (1) chamber 3/4ths water (liquid).
