Description
Technical field
The utility model relates to a kind of radiator temperature control valve, specifically, relates to and a kind ofly can prevent from the heat-operated valve that leaks outside to belong to the valve manufacturing according to the dynamic seal (packing) of thermostat valve continuous motion stem stroke.
Background technique
Traditional heat supply in winter heating pipe radiator heat water flow control is to regulate by common gate valve, stop valve etc. are installed, reasonable then is that manual thermostat valve is installed, need change according to room temperature and often carry out manual rate-of flow adjusting, use inconvenience very.In order to reach heating effect preferably, this just makes many users that valve flow is adjusted to maximum, even room temperature is overheated and need open the window aeration-coolingly, has caused the significant wastage of the energy.
Progressively bright and clear along with the increasingly serious of building energy conservation situation 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 ", have clearly stipulated " newly-built dwelling house 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 the newly-built dwelling house design and installation in Beijing radiator thermostatic valve.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 thermostatic 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 generation deformation and is driven flexible push rod and be subjected to displacement, and makes continuous motion stem move up and down thus, average per season times of exercise be about 5000 times, realize the opening and closing of valve, reach the purpose that regulates the room temperature.This radiator temperature control valve 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 piston sleeve 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 and change very inconvenience, thermostat valve leaks and has caused user's indoor article to damage on the other hand, cause the certain economic loss, influence 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.
In order to overcome the problem that existing radiator temperature control valve leaks; radiator thermostat valve carries out following architecture advances in the market: a protective cap is set between radiator valve and valve body; this protective cap bottom is connected with the piston sleeve that is sleeved on the continuous motion stem outside; the top is provided with the corresponding through hole of flexible push rod with radiator valve; in protective cap, be provided with a piston; the through hole that flexible push rod sees through the protective cap top promotes piston; piston drives the continuous motion stem motion; protective cap; piston cooperates the connection part with continuous motion stem and piston sleeve to seal, and at the piston periphery rubber packing is installed.Liquid moves up along continuous motion stem under pressure of return water, when overflowing piston sleeve, can be inside and outside the rubber packing produces big pressure reduction, the rubber packing barrier liquid that deforms, and then avoid liquid leakage.But, in actual applications, this thermostat valve only under the bigger situation of pressure of return water, can produce big pressure reduction inside and outside the rubber packing, making the rubber packing deform could leak outside by barrier liquid, and in the daily use, pressure of return water can't be very big, can not satisfy the pressure reduction that the rubber packing produces deformation, therefore, the rubber packing can not play the sealing effect of expection, still the situation of leaking can occur.
