Abstract

PURPOSE:To prevent idling by opening a valve through a spring incorporated at the branch side of valve body immediately upon droppage of vacuum in the water suction tube to disable pumping then pushing a switch lever by means of said valve and opening the pump motor circuit. CONSTITUTION:It is comprosed of reverse T-shaped valve body 1 to be inserted into the water suction tube of pump, a spring 2 incorporated at the branch side, a valve 3 and a cover 6 having a microswitch 4 operating screw 5. Upon droppage of vacuum in the water suction tube to disable pumping during operation of pump, the push-up force of spring 2 will prevail because of the adsorbing pressure based on the water suction pressure of valve 3 incorporated at the branch side of valve body to open the valve 3 thus to push up the lever 4' of switch 4 by means of the upper face of said valve 3 and to open the motor circuit to prevent idling of pump, resulting in prevention of frequent occurrence of failure and consumption of energy.

Description

【発明の詳細な説明】ポンプの故障の内で水が揚らないと云うのが最も多い。[Detailed description of the invention] The most common cause of pump failure is that the water is not pumping.

ンデンサーの焼損と云う故障の併発も少くない。In other words, if air is sucked in from the outside for some reason and the vacuum pressure inside the water suction pipe drops, there are many cases where the machine is left idling for a long time if electricity is connected, which can also cause failures such as burnout of mechanical seals and motor capacitors. Not a little.

蓋（６）で構成される。This invention consists of an inverted T-shaped valve body (1) that is inserted into a water suction pipe of a pump, a spring (2) built into the branch side of the valve body (1), and a valve body (1) that is inserted into a water suction pipe of a pump.
It consists of a lid (6) equipped with 3) and a micro-skin pocket (4) and an operating screw (5).

弁本体（１）の一方はポンプ（９）の吸水口０に他方は
吸入配管０に接続し水中に至る。One side of the valve body (1) is connected to the water intake port 0 of the pump (9), and the other side is connected to the suction pipe 0, leading to the water.

ンプの空転を防止する。Thus, after completing the piping wiring, tighten the operation screw (5) to close the valve (3) to absorb water and pass current to the pump motor. Even if it is loosened to the position (12), the valve (3) is still under water suction pressure.
is completely adsorbed, and the pump can be used without any change under normal conditions. If the pump used in this condition becomes unable to pump water due to a drop in the vacuum pressure in the suction pipe for some reason, the push-up blade of spring C) will overcome the suction pressure of valve (3), and the valve (3) will is opened, and the upper surface of the valve
4) Push the lever (A) to open the motor circuit and prevent the pump from idling.

Claims

[Claims]

Inverted T-shaped valve body (
The valve (3), which is always pressed in the open direction by the spring (2) built into the branch side of 1), is manually operated during pumping to close the valve (3) and after the water is absorbed and pumped, the valve (3) is manually operated. Even if the pressure in step 3) is removed, the pump can be used normally. If the pump in use in this state becomes unable to pump water due to a drop in the vacuum pressure in the suction pipe for some reason, the spring The valve (3) is opened by (2), and the valve (4) is pushed by the valve (4) to open the pump motor and prevent the pump from idling.
