Description

The automatic excess controller of tap water or coal gas

The utility model relates to a kind of tap water or automatic excess controller of coal gas that is used to control tap water or the use of coal gas excess.

At present, the automatic excess controller of tap water of the prior art or coal gas, a general controller can only be set a kind of fixing control consumption, and its controlled quentity controlled variable can not be adjusted arbitrarily according to the needs that use, and therefore uses very inconvenient.

The purpose of this utility model is: provide a kind of easy to use, and can adjust the tap water or the automatic excess controller of coal gas of controlled quentity controlled variable arbitrarily, to overcome the deficiencies in the prior art.

The utility model is to constitute like this: it comprises housing (1), in housing (1), be provided with closed chamber (2), on the closed chamber (2) in the outlet port of housing (1), impeller shaft (3) is housed, impeller (4) and driving gear (8) are housed on impeller shaft (3), gear shaft (5) also is housed in closed chamber (2), axis (6) and clutch gear axle (7), gear (9) is housed on axis (6), spring (10), return zero clearing gear (11) and worm gear (12), on gear shaft (5), be fixed with respectively gearwheel (13) and small gear (14) with driving gear (8) and gear (9) engagement, on clutch gear axle (7), be fixed with can with the clutch gear (15) of gear (9) and return zero clearing gear (11) engagement, be arranged on outside the housing (1) with an end of the rotating shaft of the adjusting worm screw (16) of worm gear (12) engagement, inlet at housing (1) also is provided with boss (17), around boss (17), be provided with hole (18), be fixed with sealing cover (19) and end cap (23) on the top of boss (17), on sealing cover (19), be provided with circle flexible connection body (20) and a pore (21) and an aperture (22), piston (24) also is housed in housing (1), the push rod (36) that can contact with return zero clearing gear (11) is housed on piston (24), push rod (25) is enclosed within the Kong Zhongqi upper end of piston (24) and passes pore (21) and be connected with valve (26), on push rod (25), be provided with ramp blocks (27), pin (28) and connecting lever (29) also are with return spring (30), on housing (1), also be provided with the knob that resets (31) that can contact with ramp blocks (27), be fixed with driving lever (32) that can contact with connecting lever (29) and the block (34) that can contact with the positioning block (33) on the worm gear (12) on the return zero clearing gear (11), the below of going up pin (28) at closed chamber (2) is provided with a bar hole (35) that can pass through pin (28); Impeller (4) both sides in the outlet port on housing (1) are respectively equipped with left side outlet a and export b with the right side, and outlet a in a left side exports b not at sustained height with the right side.

Owing to adopted technique scheme, the utility model compared with prior art, the utlity model has easy to use, and can adjust the advantage of controlled quentity controlled variable arbitrarily.During use, earlier the utility model is installed on tap water or the gas pipe line, or be installed on the control valve of tap water or coal gas, during work, when water or coal gas through the hole (18) of the import of housing (1) and boss (17) when left side outlet a and right outlet b flow out, to promote impeller (4) rotates by certain direction, and return zero clearing gear (11) is rotated by driving gear, when water consumption or gas consumption reach limiting the quantity of of setting, return zero clearing gear (11) will drive the position that driving lever (32) on it turns to connecting lever (29) together, at this moment driving lever (32) will promote connecting lever (29) and push rod (25) rotates together, pin (28) is dropped in the bar hole (35), at this moment push rod (25) will drive valve (26) action, thereby pore (21) is blocked, at this moment the pressure of sealing cover (19) top is greater than below pressure, sealing cover (19) action is downwards sealed the port of boss (17), tap water or coal gas have so promptly been closed automatically, after tap water or coal gas are closed, the pressure that acts on the piston (24) will be less than the power of spring (10), return zero clearing gear (11) moves upward under the effect of spring (10) and breaks away from engagement with clutch gear (15) like this, when it breaks away from engagement, return zero clearing gear (11) under the effect of spring torsion with the block (34) of backward rotation on to it with till positioning block (33) on the worm gear (12) contacts, by regulating worm screw (16) rotation worm gear (12) is the position of can regulate positioning block (33), thereby reaches the purpose of regulating tap water or coal gas controlled quentity controlled variable; When pressing button (31), the push rod of its button (31) promotes the ramp blocks (27) on the push rod (25), push rod (25) is moved upward, when the pin (28) on the push rod (25) is higher than bar hole (35), because a tangential component is arranged on ramp blocks (27), this component can make push rod (25) rotate a minute angle, thereby make pin (28) stagger bar hole (35) the position and be stuck on its edge, push rod (25) makes valve (26) leave pore (21) like this, thereby recovers the circulation of tap water or coal gas.
