Description

A linearly adjustable temperature control valve

technical field

The utility model relates to the technical field of temperature control valves, in particular to a linear adjustment temperature control valve.

Background technique

Temperature control valve, also known as radiator thermostatic controller, has been widely used in new residential buildings in my country in recent years, and the temperature control valve is installed on the heating radiator of residential and public buildings. The temperature control valve can set the room temperature according to the different requirements of users. Its temperature sensing part continuously senses the room temperature and automatically adjusts the supply of heat at any time according to the current heat demand to prevent the room temperature from overheating and achieve the highest comfort for the user.

The thermostatic valve is composed of a thermostatic controller, a flow regulating valve and a pair of connectors. The core component of the thermostatic controller is the sensor unit, that is, the temperature bulb. The temperature bulb can sense the change of ambient temperature to produce volume change, drive the valve core of the regulating valve to produce displacement, and then adjust the water volume of the radiator to change the heat dissipation of the radiator.

The temperature sensor package and the valve body of the temperature control valve are generally assembled into a whole, and the temperature sensor package itself is the on-site indoor temperature sensor. If necessary, a remote temperature sensor can be used; the remote temperature sensor is placed in the room that requires temperature control, and the valve body is placed in a certain part of the heating system. The temperature control valve is divided into two-way temperature control valve and three-way temperature control valve. The three-way temperature control valve is mainly used in a single-pipe system with a spanning pipe. Its diversion coefficient can be changed in the range of 0 to 100%, and the flow adjustment has a large room, but the price is relatively expensive and the structure is more complicated. Some two-way temperature control valves are used in two-pipe systems, and some are used in single-pipe systems. The two-way thermostatic valve used in the double-pipe system has a larger resistance; the resistance used in the single-pipe system is smaller.

The temperature control valve (temperature control valve) can be divided into self-operated temperature control valve and electric temperature control valve. The liquid expansion in the temperature sensor is uniform, and its control function is proportional regulation. When the temperature of the controlled medium changes, the volume of the temperature-sensing liquid in the sensor expands or contracts with it. When the temperature of the controlled medium is higher than the set value, the temperature-sensing liquid expands and pushes the spool down to close the valve, reducing the flow of the heating medium; when the temperature of the controlled medium is lower than the set value, the temperature-sensing liquid shrinks and the return spring pushes The valve core opens, increasing the flow of heat medium.

When the traditional self-operated temperature control valve adjusts the flow, the size of the flow through hole on the valve core is fixed. When the temperature bulb expands and contracts, the exposure degree of the through hole will change. In the case of through-holes, since the size of the through-holes remains unchanged, the liquid entering the through-holes will remain at the bottom of the unexposed through-holes, resulting in inaccurate flow control.

When assembling, it is necessary to select a connecting rod with a suitable length to ensure that when the temperature bulb shrinks to the maximum value, the groove bottom of the groove is the same height as the highest end of the inner wall of the liquid inlet.

Preferably, the length of the groove along the axial direction of the valve core is greater than the diameter of the liquid inlet.

Preferably, the length of the groove along the radial direction of the valve core is not less than half of the diameter of the valve core.

The rod transmits the water temperature to the temperature bulb, and the bulb expands and contracts when it senses the water temperature. When the water temperature is high, the bulb expands and pushes the valve core to move down the plunger through the connecting rod, and the groove exposes the part of the plunger. When the temperature of the water flow is high to a certain extent, the expansion of the temperature bulb makes the groove on the valve core fully engage with the plunger to realize the blocking of the water flow; on the contrary, when the water temperature decreases, When the bulb shrinks, the valve core is moved upward by pulling the connecting rod, the part of the plunger exposed by the groove on the valve core increases, and the water flow through the groove increases.
