CN201187620Y - Water tower dual-purpose ball float valve - Google Patents

Abstract

The utility model relates to a dual-purpose floating valve for a water tower, which comprises a valve body 1, a valve core 2, a sealing rubber 11, a floating ball 7, a connecting rod 8 and a racking arm 9. The dual-purpose floating valve is characterized in that a touching switch 3 is fixed above the valve body 1, and a touching sheet 5 is fixed at the tail end of the valve core 2. Through arranging the touching switch, the dual-purpose floating valve solves the technical problem that when the pressure of a water inlet is not large enough or the water is cut off, a water pump can not be started to supply water so as to ensure the normal operation of a water tower. The utility model is especially suitable for being installed and used in high-position water towers.

Description

Water tower dual purpose float valve

technical field

The utility model relates to a ball float valve, which is especially suitable for installation and use in high-level water towers.

Background technique

The float valve is a special valve used to control the water level. The buoyancy effect type float valve that is widely used at present is to use the buoyancy generated by the float to convert the pressure of the rubber pad through the transmission of the lever to stop the water flow. When it is not big enough or if the water is cut off, it will lose its effect.

Contents of the invention

In order to solve the deficiencies of the prior art, the utility model provides a dual-purpose float valve for water towers that can ensure automatic water supply when the pressure at the water inlet is not high enough or when the water is cut off.

The purpose of this utility model is achieved in the following manner. The water tower dual-purpose floating ball valve includes a valve body, a valve core, a sealing rubber, a floating ball, a connecting rod and a rocker arm. It is characterized in that a touch switch is fixed above the valve body, and the valve core The tail end is fixed with a touch piece, and with the displacement of the spool, the touch piece can press or loosen the touch head of the touch switch.

Compared with the prior art, in addition to automatically supplying water under normal water supply pressure, the utility model can also turn on the water pump to supply water by touching the switch when the water inlet pressure is not high enough or when the water is cut off, so as to ensure the normal operation of the water tower. .

Accompanying drawing is the structural representation of the utility model.

Detailed ways

The specific implementation of the utility model will be described in detail below in conjunction with the accompanying drawings, but it should not be understood that the scope of the above-mentioned subject of the utility model is limited to the following examples. On the premise of not departing from the above principles and contents of the utility model, it is not difficult to make various equivalent substitutions and changes, but the technologies realized thereby should be included in the scope of the utility model. :

The utility model includes a valve body 1, a valve core 2, a sealing rubber 11, a floating ball 7, a connecting rod 8, a rocker arm 9, a touch switch 3, a touch head 4, and a touch piece 5, and the touch switch 3 is bonded to the valve On the body 1, the tail end of the valve core 2 has internal thread drilling along the center line, and the screw 6 fixes one end of the touch piece 5 to the tail end of the valve core 2, and the other end of the touch piece 5 is connected to the touch head of the touch switch 3 4 close. Its working principle is as follows: when the tap water supply is normal, when the water level of the water tower drops, the floating ball 7 falls, and the valve core 2 moves to the outside of the valve through the connecting rod 8 and the rocker arm 9, and the tap water flows through the water inlet 12 and the water outlet 10 To supply water to the water tower; and when the pressure of the water inlet 12 is not large enough or the water is cut off, the well water pump can be used to supply water, that is, when the floating ball 7 falls and the touch piece 5 and the touch head 4 are released, the two sides of the touch switch 3 When the two reeds are combined, the water pump automatically supplies water to the water tower. When the water level in the water tower rises, the rocker arm 9 drives the valve core 2 to shift, and the touch piece 5 moves accordingly, pressing the touch head 4 to make the two springs of the touch switch 3 When the piece is disconnected, the water pump automatically stops supplying water to the water tower.
