Abstract

The utility model provides an automatic stop valve with timing alarm. The automatic stop valve with timing alarm is connected by a timer, an alarming buzzer and a valve core in the valve body. The automatic stop valve with timing alarm can preset the opening time and closing time of a valve through a cam sheet mounted on a transmission shaft, valve core push rod mounted on the valve core and a spring mounted in the valve body, so the automatic stop valve with timing alarm can achieve the timing alarm and timing close purpose. The automatic stop valve with timing alarm can be used for the industry and the family to automatically close the liquid pipe line and the gas line according to time.

Description

Automatic stop valve with time alarm

The utility model relates to a kind of valve, particularly about a kind of timing alarm automatic-closing valve.

Existing valve is various, but do not have the function of closing automatically, particularly existing gas valve is as civilian coal gas, the stove and accessory control valve of liquefied petroleum gas (LPG), can only control the size of its gas flow, can not timing alarm or timing automatic close, this just can often take place because stove fire is put out in water or meal boiling, cause the leakage of gas, gently then waste gas, heavy then injure the person, bring loss for people's property and life safety.

But the purpose of this utility model provides the valve that a kind of timing alarm, timing automatic are closed.

Technical solution of the present utility model is: a kind of timing alarm automatic-closing valve, it is characterized in that: in housing 1, timer 2 is housed, be connected to buzzer 7 on the timer 2, pass through initiatively drive sleeve 6 in the timer 2 lower end, driven drive sleeve 9 and interior shaft coupling 8 thereof are connected with transmission shaft 10, transmission shaft 10 bottoms are connected to cam bit 17 and cam bit 18, be connected to bumping post 23 on the cam bit 18, housing 1 lower end is connected to valve body 24, the two ends of valve body 24 are provided with takes over 16, conduit 13 is housed in the valve body 24, conduit 13 is provided with through hole 25, and spool 14 is housed in conduit 13, and an end and the spring 12 of spool 14 join, the other end and valve head 15 join, and also are connected to spool push rod 11 on spool 14.

Described timer 2 is made of dial 3, pointer 4, dust-proof cover 5, turn-knob 26 and interior clockwork spring thereof.

Described cam bit 17 and transmission shaft 10 interference fit, the edge of cam bit 17 is processed into

Type, cam bit 18 and transmission shaft 10 Spielpassung, the edge of cam 18 is processed into

Type.

The utility model with prior art compare have rational in infrastructure, as also not taking measures just to close automatically, can prevent gas leakage effectively behind the timing alarm, just ensure that peace is not as also taking measures to close automatically, can prevent gas leakage effectively, advantage such as ensure safety.
