CN2172383Y - Submersible drum automatic water feeding valve controlling device - Google Patents

Abstract

The utility model relates to a control device capable of closing automatically when rising liquid reaches the predetermined liquid level. The utility model is composed of a dishing valve seat and a valve plate with a sealing gasket. The valve plate is connected with a rotation shaft and an operating lever into a whole. A submersible drum and a closing weight iron are respectively hung up at both ends of the operating lever through suspenders or suspension rings. The submersible drum full of water has a multiple relationship with the closing weight iron. The close of a water feeding valve is regulated automatically by the buoyancy of the liquid in a reservoir or a water tank. Compared with the existing float valve or hydraulic valve, the utility model has the advantages of reliable work, small amount of maintenance, not easily worn-out parts and components, reduction of the volume by from four fifths to five sixths and uniform stress and is free from the affection of water supply pressure, and the utility model is suitable for water supply pipes with diameters of more than 75MM of reservoirs or water tanks.

Description

Submersible drum automatic water feeding valve controlling device

The utility model belongs to mechanical engineering field, is specially adapted to reach at the liquid that rises give closure when deciding liquid level.

Automatic water-supply control valve device in the background technique mainly contains two kinds of structural types, first float-ball type, the control gear of this structural type increases with caliber, and the ball float volume also increases, lever moment strengthens, strengthen thereby produce the ball float power of vacillating now to the left, now to the right, simultaneously, during water level fluctuation, lever can not be stable work, cause parts depreciation, valve closing is not tight, and generation is leaked and buried equipment; It two is hydraulic type valves, this apparatus structure complexity, and amount of maintenance is big, it is influenced by ball float also, the build-up of pressure pulsation, in the course of time, Sealing damages, and is that water pipe pressure is low excessively on the one hand again, and valve opening is restricted, its volume and weight increases greatly, price height, the water supply valve control gear of comprehensive above-mentioned two kinds of structural types, it is poor to exist functional reliability, maintenance load is big, and damage of components is many, defectives such as cost height.

The purpose of this utility model is to overcome the defective in the background technique, designs a kind of reliable operation, is not subjected to the influence of water level fluctuation and pressure of supply water, reduces parts wear and submersible drum type automatic water-supply control valve device simple in structure.

The technical solution of the utility model realizes as follows: an end of water supply line is equipped with the dish valve seat by flange, valve plate is opened or is closed by rotating shaft and actuating linkage rotation, end at actuating linkage hangs elongated heavy bucket by suspension rod, its the other end hangs by suspension rod and closes foundary weight, the ring packing packing ring is installed on the valve plate, actuating linkage and suspension rod can be made collapsible rod member, and heavy bucket can be that several kegs are installed in series.

The utility model is compared with background technique, its simple in structure, easy to manufacture, reliable operation, its weight has only 1/5～1/6 of identical bore float-ball type, have that action is gentle slow, stressed evenly, component are not easy to wear, almost there is not any maintenance load, characteristics such as be not subjected to that pressure of supply water influences, its is suitable for water supply line diameter and uses on the reservoir more than the 75mm, water tank.

Fig. 1 is the utility model scheme of installation;

Fig. 2 is the utility model valve working schematic representation;

Fig. 3 is the utility model valve board structure figure.

Accompanying drawing is a specific embodiment of the present utility model, is described further below in conjunction with accompanying drawing:

With reference to Fig. 1, by flange water supply line (1) and dish valve seat (2) are coupled together with screw, valve plate (3) is installed in the dish valve seat, valve plate (3) is connected as a single entity with rotating shaft and actuating linkage (4), end at actuating linkage (4) hangs heavy bucket (5) by suspension ring, and its other end hangs by suspension rod (7) and closes foundary weight (6).

With reference to Fig. 3, be a spherical sealing surface (9) at the two ends end face of valve plate (3), below sphere close (9), be provided with the ring packing packing ring (8) of symmetry.

With reference to Fig. 2, when in the heavy bucket during filled with water, because of the water in the heavy bucket (5) is the multiple of closing foundary weight (6) weight, heavy bucket (5) drops to bottom on one side, the gradient and the valve plate (3) of actuating linkage this moment (4) are 45 °, be maximum open position, along with the water of water supply line (1) continue to flow into water storehouse or water tank, progressively flood heavy bucket (5), the weight of heavy bucket is just more and more lighter, when the liquid level of reservoir or water tank constantly raises, close the residuals weight of foundary weight (6) weight greater than heavy bucket (5), actuating linkage (4) beginning is tilted to closing direction, and valve plate (3) turns down gradually, if water output is during greater than water consumption, reservoir or water tank level are also in continuous rising, and heavy bucket (5) also continues to rise, and close foundary weight (6) and continue to descend, close fully up to valve plate (3), reservoir or water tank level are not rising; In actual use, be a bit larger tham the heavy barrel of weight partly that surfaces as long as close after the weight of foundary weight (6) deducts the buoyancy of water to itself, valve plate (3) just moves to closing the valve direction, otherwise, then open; When the water output of reservoir equaled water consumption, the unlatching angle of valve plate (3) kept a micro-adjusting situation, to making each rod member in the device be unlikely to be worn by shaking to put.

Claims (3)

1, a kind of submersible drum type automatic water-supply control valve device, it comprises water supply line (1), dish valve seat (2), it is characterized in that also having comprised the valve plate that has ring packing packing ring (8) (3) by being installed in dish valve seat (2) lining, valve plate (3) is connected as a single entity with rotating shaft and actuating linkage (4), end at actuating linkage (4) hangs heavy bucket (5) by suspension ring, and its other end hangs by suspension rod (7) and closes foundary weight (6).

2, submersible drum type automatic water-supply control valve device according to claim 1 is characterized in that actuating linkage (4) and suspension rod (7) can make collapsible rod member.

3, submersible drum type automatic water-supply control valve device according to claim 1 and 2 is characterized in that heavy bucket (5) can be that several elongated kegs are installed in series.
