Description
Technical field
The utility model relates to a kind of differential pressure balanced type float valve, is that a kind of water storage of water storage box that utilizes comes the device of the automatic control water level depth, belongs to the water supply control valve technical field.
Background technique
The float valve of the existing automatic control water level depth is to be made of intake tunnel housing, seal rubber pad, connecting rod, ball float disjunctor, described housing places the outer end, the centre is an intake tunnel, in the intake tunnel outlet port seal rubber pad is arranged, the sealing rubber cushion carries out work by ball float by the principle that connecting rod drives.During use, the water inlet of intake tunnel mouth, seal rubber pad are owing to the sagging non-resistance of ball float is opened, when the water storage tank water level rising makes the ball float come-up, ball float withstands water intake by the leverage of connecting rod with seal rubber pad, and water storage box is no longer intake to reach the purpose of automatic control water level.This kind structure is not because tap water or the hydraulic pressure that has water pump to supply water are constant, pressure of supply water vertical deviation very big (0-8KG), so there is following deficiency: 1, water storage tank water level is more shallow during low pressure; 2, water level is higher during high hydraulic pressure; Seal rubber pad was intercepted incessantly high pressure water and is caused damage when 3, hydraulic pressure was too high, thereby reduced working life.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provide a kind of mainly is to utilize the pressure of water inlet to realize that automatically the mode of pressure balance realizes controlling the water level of water storage box, and water level also be not subjected to the height hydraulic pressure variation, can with the differential pressure balanced type float valve of water storage box constant water level depth basically identical.
The purpose of this utility model is finished by following technical solution, it includes a valve body, spool, valve rod, lever and ball float, the lower water inlet of described valve body is communicated with water outlet by the valve seat in the valve pocket, is placed with one on the described valve seat by spool that can the rubber cushion seat of small size knee-action constitutes in valve pocket, offer on the described rubber cushion seat valve pocket above at least two connections with below the small through hole of water intake; Described rubber cushion seat top is equipped with valve rod, and the upper end portion of valve rod is exposed and compressed end with a lever behind the valve body and link to each other, and end, described lever centre is connected on the valve body side, and lever the other end links to each other with ball float.
Described valve body is combined by upper valve body and following valve body, and described valve rod is joined by upper ejector pin and lower push rod and forms; Described upper ejector pin underpart is provided with and the contacted cushion in lower push rod upper end, and the underpart of lower push rod is provided with and the contacted cushion spare of the middle protuberance of rubber cushion seat.
Described upper valve body top is connected to a upper sleeve body, and upper ejector pin is installed in it, is equipped with in the described upper valve body and the contacted lower push rod of upper ejector pin, and the soft rubber cushion that described rubber cushion seat is halved together by periphery is placed in down in the cavity in the valve body.
Described upper valve body is linked to each other with lever and ball float by the circular shaft pin-and-hole by side; Described soft rubber cushion is the circular soft rubber cushion of a S-shaped bending, and soft glue is lined with the small through hole that two above two sides communicate, and described soft rubber cushion is connected on the rubber cushion seat.
Described valve body down is provided with Nei Ya or outer pitch thread with the connection part of outside; Adopt screw thread between described upper valve body and the following valve body, compress or the bonding mode integrator.
The present invention compares with the technology of existing water inlet floater controlled valve, has the following advantages: 1, low hydraulic pressure water inlet is smooth and easy; 2, because of being to utilize the pressure of water own to come balanced seal, so the sealing of high hydraulic pressure is reliable; 3, very little buoyancy just can seal, so volume is little; 4, it mainly moves by the spring-back force of soft rubber cushion, so long service life.
