How to choose the temperature control valve of automatic radiator correctly

[regulating valve 】With the reform of the heating system, household heat metering and room temperature control have begun to enter the implementation stage It is very common to install temperature control valve on the radiator Using temperature control valve to achieve room temperature control, not only can Zui greatly save energy, but also can Zui greatly meet the needs of different users for indoor temperature regulation, which is a good thing for the country and the people But how to choose The selection of temperature control valve is not completely mastered by the user If the product cannot be selected correctly, it will not only fail to meet the demand, but also may bring unnecessary economic loss to the user Here, I will introduce some selection of small stealing door to you Temperature control valve refers to a device installed on the radiator water supply pipe for temperature regulation (actually flow regulation) It can be divided into manual temperature control valve and automatic temperature control valve Automatic temperature control valve is also called self operated temperature control valve or automatic temperature control valve, which is also called thermostatic valve for short The automatic temperature control valve is composed of a self-propelled actuator of a temperature sensor and a special matched temperature control valve body The structure of the temperature control valve body often has two kinds of Zui common two-way valves: straight through valve and angle through valve Two way valve is mainly used in double pipe system or new single pipe system specially designed In recent years, according to the differences between single and double pipe systems, graduate students have produced three-way temperature control valves specially suitable for single pipe systems and four-way valves specially designed for single and double pipe systems with concealed installation At present, these four-way valves are mostly found in imported products Giacomi-ni's four-way valve is not only suitable for various radiators, but also for single and double pipe systems At the same time, it also has a connection mode that can meet the requirements of concealed multiple pipes There are usually two kinds of temperature control valve, manual and automatic The operation principle of the valve is very different The manual temperature control valve usually adopts the screw lifting valve core, and the rotation of the handle changes into the linear displacement of the valve core through the screw In order to adapt to the special straight-line movement mode of the self-propelled actuator of the temperature sensor, the movement of the valve core is usually designed as the straight-line displacement which can be reset automatically, so the two valve bodies cannot be interchanged in general But there are also interchangeable special design valve body can be universal, that is, the valve body with automatic temperature control valve and a suitable manual screw lifting mechanism can realize the universal exchange of manual and automatic This improvement is particularly suitable for China's national conditions and is of great practical value In many projects at present, in order to save the initial investment of developers, a valve body with automatic temperature control function is installed first and a special screw lifting handle is attached In this way, the manual temperature control valve is realized by using 1 / 3 of the cost of the automatic temperature control valve (the price is basically equal to the manual temperature control valve), and the manual temperature control valve is also used The realization of automatic temperature control in the future leaves room for upgrading This kind of product is rare even in the imported products Italy's jacomini is ahead of the market in this respect It provides this kind of double regulating temperature control valve between manual and automatic temperature control valves It is convenient to set the indoor temperature with eight gears Worthy of being the world's largest supplier of HVAC valves Because of the particularity of the valve between manual and automatic temperature control valve, the selection will be more complex This complexity has created a "mixed vision" opportunity for some people who are not proficient in business and speculative operators           In the current market, there are many operators of automatic temperature control valve suppliers who recommend the pure automatic temperature control valve body with a simple regulating handle as a dual regulating temperature control valve to users Some users also use such a temperature control valve, which is not appropriate and has great potential Although such an automatic temperature control valve body is attached with a simple regulation Handle, but the design idea of the handle is to meet the need of temporary system adjustment to meet the engineering pressure test and water test before the installation of the automatic temperature control valve head After the completion of the pressure test and water test process, the handle is replaced by the automatic temperature control valve head Because of its temporary nature, the simple control handle borrows the original ordinary valve head used to fix the temperature control valve head on the valve body The thread is used for screw lifting.
