Mechanical valve device

Abstract

The invention provides a mechanical valve device. The mechanical valve device comprises a valve body, a fixed frame, a temperature-sensing glass ball, a movable body, an adjusting wheel, a valve core, a spring, a spring seat, a cone part and a nut. T he valve core is assembled in the valve body; the cone part, the spring seat and the spring are connected successively in the valve core; the valve core at the end connected to the spring is a through hole, one end of the spring is connected to the spring seat while the other end of the spring is connected to the inner wall of the valve body, and the spring is in an oppressed state; the movable body is connected to the outer wall of the valve core to limit the valve core; the fixed frame comprises a fixed sheet, a supporting sheet, a clamping sheet and a fixed rib. A ball locating hole is formed in the fixed sheet, one end of the fixed sheet is connected to the supporting sheet, and the connecting angle is greater than 90 degrees; a locating groove is formed in a position, corresponding to the fixed rib, of the valve body, and the fixed rib is connected to the locating groove in an inserting manner. According to the mechanical valve device provided by the invention, the bending angle of the fixed frame and the fixed rib are additionally arranged, so that the strength and the rigidity of the mechanical valve are improved, and the service life of the mechanical valve device is longer.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a mechanical valve device that uses compressed air as a working medium to transmit movement and power, and forcibly opens a ventilation mechanism after a fire occurs. Background technique [0002] At present, ventilation windows are installed in various buildings. There are many patents on automatic opening or closing of ventilation windows, most of which are controlled by single-chip microcomputers and motors. The structure is complicated, the cost is high, and a power supply device is required. All are provided by electric energy, once the electric energy is lacked, the device for opening or closing the ventilation window will not work, thus losing all its functions. [0003] Today, fire is a common catastrophic problem faced by people all over the world. It has caused many serious losses of life and property to human society. With the development of the economy, high-...

AI Technical Summary

Problems solved by technology

However, this opening device still has great deficiencies. For example, 1. The connection between the fixed frame and the valve body requires elastic cylindrical pins. The defect is that the elastic cylindrical pins are difficult to assemble. Risk of falling off; 2. The length of the threaded connection between the nut and the valve body is short, such as the failure of the threaded connection under high pressure, resulting in the failure of the entire valve, etc.
