Description
Technical field
The utility model relates to a kind of thermostat valve leakage protection device, relates in particular to a kind of heating hot water waterpipe leak preventing device for thermostat valve, belongs to the thermostat valve field.
Background technique
Progressively bright and clear along with the increasingly serious of Situation of the architectural energy saving and heat metering direction, the radiator thermostatic control valve progressively gets the nod.Eight ministries and commissions such as the Ministry of Construction in 2005, National Development and Reform Committee put into effect " about the suggestion of further propelling urban heating system reform ", clear " New Dwelling and public building must be installed heat meter and radiator thermostatic control valve before the building ".On February 1st, 2007, Beijing new " energy Saving Design of Residential Buildings standard " comes into effect, and this standard has been made mandatory provision to Beijing's New Dwelling design and installation radiator constant temperature valve.The provinces and cities such as Liaoning have also put into effect corresponding design standard for energy efficiency of buildings in succession, and it is trend of the times that thermostatic valve gets the nod in higher energy conservation standard.
Radiator constant temperature valve in the market all is to adopt valve body and a radiator valve of being contained on the radiator water pipe to form, wherein, radiator valve comprises heat responsive element and a flexible push rod, piston sleeve is installed on the valve body, be coated with continuous motion stem in the piston sleeve, when radiator valve and valve body were assembled into one, the flexible push rod of radiator valve and the continuous motion stem on the valve body joined and remain on the same axis.When indoor temperature change generated in case, the heat responsive element of radiator valve is experienced temperature variation and is expanded with heat and contract with cold and drive flexible push rod and be subjected to displacement, thus so that continuous motion stem move up and down, height according to supply water temperature, heat responsive element measures indoor actual temperature, temperature variation is expanded with heat and contract with cold, and regulates the size of this valve flow, and the individual who reaches each room presets temperature.Average per season, times of exercise was about 5000 times, realized the opening and closing of valve, reached the purpose that regulates the room temperature.This temperature control valve for heat dissipator is because the prolonged exercise of continuous motion stem, at continuous motion stem be sleeved on the water leakage phenomenon that can produce poor sealing between the O-ring seals of continuous motion stem outside, this has just caused general thermostatic valve all will to be safeguarded or change every year, use on the one hand replacing very inconvenient, thermostat valve leaks and has caused user's indoor article to damage on the other hand, cause certain economic loss, affect the user and use.Therefore the leak-proof protection device of thermostatic valve is just extremely important, and most thermostatic valve do not have drip-preventing function substantially, uses very inconvenient.In case the generation liquid leakage will cause the economic loss that is difficult to retrieve to the user.
The problem of leaking in order to overcome existing radiator temperature autocontrol valve in the automatic constant-temperature control valve that sell the Chinese market field now, comprises that all in the import brand all is to utilize the up and down two-layer O type circle in the spool to seal.Add that again the temperature in heating is high because the water quality in the north is harder, O type circle wears out serious, and valve rod easily produces incrustation scale in circulating water, is bonded in the wearing and tearing generation that easily produces O type circle on the valve rod at the rear incrustation scale of the reciprocal operation of long-time high temperature and leaks.
