Abstract
The utility model discloses a water feeding valve for a low level cistern, which is composed of a floating ball, a floating ball lever, a lever supporting base, a water sealing ring, a valve body, a water outlet, etc., wherein the floating ball is fixedly connected with one end of the floating ball lever, the middle part of the floating ball lever is hinged and supported on the lever supporting base, the lever supporting base is fixedly connected with the valve body, and the water sealing ring is arranged between a water inlet and a water outlet of the valve body. Besides, the utility model is also provided with a pressing screw rod which is connected with the other end of the floating ball lever by screw threads, and the end of the pressing screw rod, which extends from the floating ball lever is abutted on the water sealing ring. The water outlet on the valve body extends downwards to the middle lower part of the water feeding valve. The utility model has the obvious advantages of simple structure, reliable operation, convenient maintenance, no noise, etc.
Description
The utility model relates to a kind of valve of controlled water flow, especially a kind of architecture advances of inlet valve.
Existing low level cistern water intaking valve is made up of ball float, floating ball lever, lever support, pressure transmission bar, valve body etc. usually, and an end of floating ball lever has the pressing boss, and valve body top has delivery port.When lower water box internal cause lack of water, when ball float fell, hydraulic pressure made valve open with jack-up water shutoff circle, and in the case, current are by valve body, in the delivery port inflow water tank on valve body top.Along with the continuous rising of water level in the water tank, ball float floats gradually, and the pressing boss of floating ball lever one end compresses the water shutoff circle gradually by the pressure transmission bar, and valve is closed automatically.The pressing boss height of this low level cistern water intaking valve floating ball lever one end is fixed, and therefore is difficult to guarantee that floating ball lever is in desirable installation site, can not guarantee the water intaking valve reliably working, and is especially all the more so behind parts wears such as water shutoff circle.In addition, the delivery port of this water intaking valve is positioned at valve body top, and at the water inlet initial stage, delivery port is higher than liquid level, and therefore noise is arranged.
The purpose of this utility model is: the problem at above-mentioned existing low level cistern water intaking valve exists is in the low level cistern water intaking valve that the water intaking valve reliably working is guaranteed in desirable installation site all the time thereby propose a kind of floating ball lever that can guarantee.
Further purpose of the present utility model is: at having the low level cistern water intake valve initial stage now the problem of noise is arranged, propose a kind of noiselessness low level cistern water intaking valve.
In order to achieve the above object, low level cistern water intaking valve of the present utility model contains ball float, floating ball lever, lever support, water shutoff circle, valve body, delivery port, ball float is connected in an end of floating ball lever, the middle part of floating ball lever is hinged on lever support, lever support and valve body are connected, and the water shutoff circle is housed between the water inlet of valve body and the delivery port.In addition, also contain the pressing screw rod, the other end of described pressing screw rod and floating ball lever is by being threaded, and the pressing screw rod is resisted against on the water shutoff circle from the external part on the floating ball lever.In order to arrive the further purpose of the utility model, valve body upper water-out mouth extends downwardly into the middle and lower part of water intaking valve.
Since the pressing screw rod with an end of floating ball lever by being threaded, therefore can regulate the length that the pressing screw end head stretches out from floating ball lever, thereby guarantee that floating ball lever is in desirable installation site all the time, guarantees the water intaking valve reliably working, even still like this when parts wears such as water shutoff circle.In addition, this regulatory function can also realize the control of water intake velocity by the change to water shutoff circle pressure, and low level cistern water intaking valve of the present utility model is used more as people's will.The downward extension of valve body upper water-out mouth makes water inlet be lower than liquid level all the time, and in addition with the downward guiding function of current, whole water inlet process does not have noise.This shows, the utlity model has remarkable advantages such as simple in structure, reliable operation, maintenance convenience, noiselessness.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of an embodiment of the utility model.Its component title sequence number is ball float 1, floating ball lever 2, pressing screw rod 2-1, lever support 3, pressure transmission bar 4, valve cover 5, water shutoff circle 6, valve body 7, delivery port 7-1, water inlet 7-2, sealing ring 8, locking nut 9.
Low level cistern water intaking valve among Fig. 1 is made up of ball float 1, floating ball lever 2, lever support 3, pressure transmission bar 4, valve cover 5, water shutoff circle 6, valve body 7, sealing ring 8, locking nut 9.Ball float 1 is connected in an end of floating ball lever 2 by screw thread, the middle part of floating ball lever 2 is hinged on lever support 3, the other end of floating ball lever 2 is stated pressing screw rod 2-1 by being threaded, pressing screw rod 2-1 is resisted against on the water shutoff circle 6 by pressure transmission bar 4 from the external part on the floating ball lever 2, lever support 3 is connected with the screw thread pressing of valve body 7 by valve cover 5, have water inlet 7-2 and delivery port 7-1 on the valve body 7, between water inlet 7-2 and the delivery port 7-1 water shutoff circle 6 is housed, delivery port is 90 ° of elbow shapes, extend downwardly into the bottom of water intaking valve, sealing ring 8 and locking nut 9 are used to guarantee being tightly connected of water intaking valve and lower water box.
Experiment shows, this low level cistern water intaking valve is easy to operate, reliable operation, noiselessness.
