Problems solved by technology

This temperature control valve should generally be used in high-pressure cleaners. Although it can sense water temperature and generate corresponding actions, it cannot be used in water floor heating systems.
The reasons are as follows: 1. The temperature control valve is opened with the rise of water temperature at the water inlet, while the thermostatic valve in the water floor heating needs to be closed with the rise of water temperature at the water inlet; 2. The temperature control valve cannot Adjust the set temperature value

Embodiment 1

[0036] Such as Figure 1 to Figure 4 As shown, the local heating thermostatic valve includes a valve body 1, a temperature bulb 2, a valve core 3, a spring one 6, a spring two 7 and an adjustment mechanism.

[0037] Specifically, the valve body 1 has a sealing portion 1d inside, and further divides the inner chamber of the valve body 1 into a water inlet chamber 1b and a water outlet chamber 1c. On the outer wall of the valve body 1 there is an arrow 1a marking the direction of water flow.

[0038] The temperature bulb 2 includes a body 2a, a push rod 2b pierced on the body 2a, and a temperature-sensing medium 2c arranged in the body 2a. The inner end of the push rod 2b can abut against the temperature-sensing medium 2c, and the outer end passes through the body 2a. The temperature bulb 2 belongs to the prior art, and will not be described in detail here. The body 2a of the temperature bulb 2 is located in the water inlet chamber 1b, and the ejector rod 2b penetrates into t...

Embodiment 2

[0055] Such as Figure 5 As shown, the structure and principle of this embodiment are basically the same as those of Embodiment 1, the difference is that the valve core 3 is located in the water inlet chamber 1b and the valve core 3 is fixedly connected with the outer end of the ejector rod 2b of the temperature bulb 2 . The spool 3 is disc-shaped and connected as a whole with the push rod 2b. A bottom cover 19 is fixedly connected to the side wall of the water inlet chamber 1b of the valve body 1, and a top cover 12 is fixedly connected to the side wall of the water outlet chamber 1c of the valve body 1. One end of the spring one 6 is in contact with the valve core 3, and the other end is in contact with the valve core 3. The top cover 12 leans against each other; one end of the spring 2 7 leans against the body 2 a of the temperature bulb 2 , and the other end leans against the bottom cover 19 .

[0056] The top cover 12 is provided with a lift screw 15 and a lift nut 14, ...

Abstract

The invention provides a floor heating thermostatic valve, which belongs to the technical field of engineering components, and solves the problem that the set temperature value cannot be adjusted along with the temperature increasing of water at a water inlet in the conventional thermostat valve. The floor heating thermostatic valve comprises a valve body with a sealing part; the inner cavity of the valve body is divided into a water inlet cavity and a water outlet cavity; a thermal bulb and a valve plug are arranged in the valve body; a thermal bulb body is positioned in the water inlet cavity; the thermal bulb is connected with the valve plug, when water temperature in the water inlet cavity is increased, the thermal bulb can drive the valve plug to move close to the sealing part; an elastic piece which ensures that an ejector rod of the thermal bulb can be contracted into the thermal bulb body when the water temperature in the water inlet cavity is reduced is arranged between the thermal bulb and the valve body; and an adjustment mechanism for adjusting the length of the ejector rod penetrating through the body is arranged between the side wall of the water outlet cavity of the valve body and the thermal bulb. The floor heating thermostatic valve has the advantages of high running safety performance, wider application range and accurate adjustment, can control the temperature accurately and sensitively, and is convenient to use.

Description

technical field [0001] The invention belongs to the technical field of engineering components, and relates to a valve, in particular to a floor heating thermostatic valve. Background technique [0002] Floor heating is the abbreviation of radiant floor heating. It uses the whole ground as a radiator, heats the whole ground evenly through the heat medium in the radiant layer of the floor, and uses the heat storage and heat radiation of the ground itself to conduct from bottom to top to achieve The purpose of heating. Compared with traditional heating methods, geothermal radiant heating has many characteristics such as comfort, sanitation, and health care; saving space and beautifying the living room; high efficiency and energy saving; good thermal stability; low operating costs; strong adaptability and long service life. This technology is not only widely used in residential buildings, hospitals, shopping malls and other public buildings, but also in football fields, vegetab...
