Description

Ball float inlet valve

Technical field

The utility model relates to ball float inlet valve, especially for the ball float inlet valve of various water replenishing devices.

Background technique

In prior art, the moisturizing of steam disinfection cabinet is controlled, the moisturizing of rice steaming car is controlled, the moisturizing of boiler is controlled, and the conventional toilet moisturizing control of people etc., all adopt floater controlled valve to control moisturizing liquid level, as, at application number, be 99230446.6, notification number is in the Chinese patent of CN2386090, a kind of structure of water tank of automatic water supplement is disclosed, comprise housing, exhaust port, intake pipe, ball float and be arranged on the osculum of housing bottom, feature is that intake pipe is arranged on housing top, in water inlet, place arranges inlet valve, lever is set below spool, lever one end connects ball float by push rod, make the stable level of automatic water supplement, its inlet valve is by the connecting rod that is hinged on casing, to connect ball float to complete control action, when rising, ball float also and then rises at the Sealing that approaches rounded end, while rising to predetermined fluid level, Sealing seals the water outlet of intake pipe, when water level declines, ball float drivening rod declines, the Sealing that approaches rounded end is also and then declined, it is the water outlet that Sealing leaves intake pipe, make to carry out moisturizing from intake pipe.The shortcoming of this structure is: rod hinge connection is too abundant at the hinging hole of casing, when service time is long, has after incrustation scale, and hinging hole is easily blocked even by dead, and reaction is insensitive automatically to cause floater controlled valve.

Above-mentioned floater controlled valve is ball float inlet valve of the present utility model.

Summary of the invention

In order to overcome the deficiencies in the prior art, the problem that the utility model solves is to provide a kind of moisturizing sensitive ball float inlet valve.

The utility model solves the technological scheme that its technical problem adopts: a kind of ball float inlet valve, comprises housing; Intake pipe, this intake pipe has waterexit end; Water outlet, this water outlet and waterexit end Joint are logical; Ball float; Connecting rod, one end and the ball float of this connecting rod are affixed; Water shutoff connecting rod, the other end that this one end is relative and water shutoff connecting rod are affixed; Seal, the sealing that matches of sealing body and water outlet; Seal seat, sealing body is fixed on seal seat; Fixing device, this fixing device is located on intake pipe; This water shutoff connecting rod is L-shaped stainless steel plate body stamping part, the affixed seal seat in the vertical edge plate back side that this is L shaped, and this affixed this other end in plate end, L shaped base, this L shaped base plate has right-angle fold plate, and this right-angle fold plate is hinged on housing.

Beneficial effect: because water shutoff connecting rod adopts stainless steel plate body stamping part, the formed right-angle fold plate of stainless steel plate body stamping part is hinged on housing, the thickness of its hinged contacting point is the thickness of slab of stainless steel plate body, hinged contacting point is compared with the rod hinge connection hole of prior art, seem frivolous, be not easy to be stopped up by incrustation scale, rotate flexibly hinged place, has solved the sensitive problem of ball float inlet valve water replenishing of the present utility model.

Further improvement as to technique scheme, also comprises the manger board that is fixed on housing.This improvement makes from intake pipe current out, the impact in pond to be slowed down, and the spray that the water surface in pond is caused weakens.

As to technique scheme concrete scheme, fixing device comprises stainless steel baffle ring, the sealed silicon cushion rubber being welded as a whole with intake pipe and the fastening piece being threaded with intake pipe, and sealing silica gel ring is taper.

As the further improvement to technique scheme, the inner ring of stainless steel baffle ring has N positioning hole, N >=1, and housing has N the locating stud of correspondence with it, and this locating stud and this positioning hole are suitable.Above-mentioned improvement is accurately convenient for locating between stainless steel baffle ring, shell and intake pipe in manufacturing process, has improved manufacturing efficiency.

Embodiment

Below in conjunction with drawings and Examples, the utility model is further illustrated.

With reference to Fig. 1, a kind of ball float inlet valve, comprises housing 1; Intake pipe 2; Water outlet 3; Ball float 4; Connecting rod 5; Water shutoff connecting rod 6; Seal 7; Fixing device 8; Seal seat 71; Manger board 9.Intake pipe 2 has waterexit end 21; Water outlet 3 is logical with waterexit end 21 Joints; One end 51 of connecting rod 5 is affixed with ball float 4; , the relative the other end in one end 51 52 is affixed with water shutoff connecting rod 6; The sealing that matches of seal 7 and water outlet 3; Seal 7 is fixed on seal seat 71; Fixing device 8 is located on intake pipe 2; Water shutoff connecting rod 6 is L-shaped stainless steel plate body stamping part, these L shaped vertical edge plate 61 affixed seal seats 71 in the back side, the L shaped base plate 62 affixed the other ends 52 in end, L shaped base plate 62 has right-angle fold plate 63, and right-angle fold plate 63 is hinged on housing 1.Manger board 9 is fixed on housing 1.Fixing device 8 comprises stainless steel baffle ring 83, the sealed silicon cushion rubber 82 being welded as a whole with intake pipe and the fastening piece 81 being threaded with intake pipe.
