Abstract

The invention belongs to the field of mechanical parts, and particularly relates to an automatic alarm room temperature on-off control valve. A control box is arranged in a control bin. A temperature sensor is arranged on the top inside the control box. A control circuit board is arranged below the temperature sensor. The temperature sensor is connected with the control circuit board. A signal receiver is welded to the control circuit board and sequentially penetrates through the control box and a valve body. A fixed contact, a movable contact, a motor and a cylinder are arranged below the control circuit board. The movable contact is connected with the control circuit board and the motor and is perpendicularly located above the fixed contact. The cylinder is connected with the motor. A piston of the cylinder is connected with a valve rod which is fixed to the upper surface of a valve element. A through hole is formed in the bottom of the control box. The valve rod is arranged in the through hole. A seal ring is arranged between the valve rod and the control box.

Description

technical field [0001] The invention belongs to the field of mechanical parts, in particular to an automatic alarm room temperature on-off control valve. Background technique [0002] The on-off time area method is based on the water supply time of the heating system of each household, and allocates the total heat supply of the building. The specific method is to install a room temperature on-off control valve on the branch branch of each household for the horizontal heating system connected to households, and to control the circulating water of the user to realize the room temperature adjustment of the household. At the same time, a room temperature controller is placed in the representative room of each household to measure the indoor temperature and set the temperature for the user, and transmit these two temperature values ​​to the room temperature on-off control valve. The room temperature on-off control valve determines the on-off ratio of the on-off valve in a contro...
