Abstract
The utility model relates to an automatic stable pressure expander matched with a hot water heating system. The expander is composed of a tank welded by a steel plate, an inflation tube arranged on the tank, a pressure gauge, a viewing mirror, a water inlet pipe and a water outlet pipe. The tank is divided into an air chamber and a water chamber via a bag type heat-resisting rubber diaphragm, the air chamber is filled with definite gas for causing air pressure to reach the minimal pressure value required by the system, and the water chamber is communicate with a circulation pipeline and a water supply pump in the system via the water inlet pipe and the water outlet pipe. A high-level open expansion water tank in the existing hot water heating system can be replaced by the utility model, and the utility model can eliminate the problems of water impact and unbalanced hydraulic power and pressure in the system.
Description
The utility model relates to a kind of matching used automatic voltage regulation expansion gear of hot water system that is.
In the existing hot water heating, all be to adopt high-order open type expansion tank to realize steady of system press and the increase and decrease problem that solves the water capacity that causes owing to the water temperature variation, to guarantee the normal circulation of hot water in system., system is in actual motion, because the change and the mismanagement of load, therefore the frequent lack of water of high-order open type expansion tank, spilling water cause the imbalance of system water pressure, particularly when the power failure termination of pumping, internal system is easy to generate water attack, directly influences the stability and the security of system's operation.In addition, high-order open type expansion tank all is mounted in the top of heat supply uppermost storey, and it not only brings complexity to architectural design and construction, has also increased the load of construction costs and building simultaneously, and is totally unfavorable to antidetonation.
In order to address the above problem, Chinese patent 86210945 once proposed a kind of " automatic voltage regulation expansion gear ", but because it adopts in its vacuum tank is shape for hat (or claiming half film) heat resistant rubber barrier film, therefore be provided with the fixedly big flange of barrier film in the centre of tank body with regard to having to, so this big flange is set the tank body cost is increased, but also because of its sealing radius phenomenon that leaks air greatly easily.
The purpose of this utility model is that a kind of supporting automatic voltage regulation expansion gear of hot water system that is will be provided, to replace high-order open type expansion tank, it can not only guarantee safety, the stable operation of hot water system, and on construction costs and building load, also decrease, simultaneously compare low cost of manufacture, good airproof performance with half membranous type tank body.
The purpose of this utility model is achieved in that with tank body by welded steel plate of stent support, the tank body outside is provided with electro connecting pressure gauge, the visor that tank skin is provided with the inflation valve seat and observes in jar.A bag type diaphragm of rubber is housed in the tank body, and this barrier film will be divided into air chamber and hydroecium two parts in the tank body, is hydroecium in the capsule, and capsule is outward an air chamber.Tank body respectively is provided with a flange up and down, and capsule bag two ends are fixed on the flange, and lower flange communicates with the water inlet pipe and water outlet pipe of hydroecium in the tank body.Story height and pressure of supply water according to system's heat supply are made the high-low limit force value that electric contact is controlled, and before system's operation, in air chamber, inflate earlier, stop inflation when reaching the threshold pression of electric contact control, close charge valve, circulation line in the water inlet pipe and water outlet pipe on again will this jar and the system and small pump are communicated with and open the Inlet and outlet water valve and can move.
Advantage of the present utility model is it not only can to eliminate hot water system, and often waterpower, the pressure of appearance are lacked of proper care and the water attack problem, guarantee that water system is stable, safe operation, avoid the explosion accident of radiator and pipeline fittings, prolonged system service life, and floor space is little, convenient management, automatically degree is high and simple to operate, and can simplify architectural design and construction, reduce construction costs.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the longitudinal sectional view according to the automatic voltage regulation expansion gear that the utility model proposes.
Fig. 2 uses hot water system process chart of the present utility model.
As shown in Figure 1: this device is to become a tank body 2 by welded steel plate, below tank body 2, be provided with bearing 1, by bearing 1 with tank body 2 vertical support fixation, be provided with a bag type (or claiming full film) diaphragm of rubber 3 in the tank body, barrier film 3 will be divided into air chamber and hydroecium two parts in the tank body 2, in the bag barrier film 3 is hydroecium, and the space between bag barrier film 3 and tank body 2 inwalls is an air chamber.The material of barrier film 3 is anti-130 ℃ of high temperature and rubber with good retractility, be provided with electro connecting pressure gauge 5 in tank body 2 outsides, pressure in order to the control air chamber changes, tank body 2 walls are provided with inflation valve seat 4, connecting charge valve fills with nitrogen or air to air chamber, on tank body 2 walls, also establish visor 7, in order to observe a jar interior situation, for overall tightness and the reduction tank body cost that improves tank body 2, the fixing upper flange 10 that is provided in a side of tank body 2 two ends and the lower flange 9 that adopt of bag barrier film 3, lower flange 9 joins with water inlet pipe and water outlet pipe 6.Flange 10 and 9 uses bolted between ring flange the upper and lower port of bag barrier film 3, and tank body 2 tops also are provided with suspension ring 11.This device charges into a certain amount of nitrogen or air during work in the air chamber, a certain amount of water of contain in the hydroecium, and communicate with systemic circulation pipeline and small pump.
With reference to Fig. 2, water (flow) direction is held full water with the softening water tank VI as shown by arrows in the system, is supplied water to system pipeline and hot water heating automatic voltage regulator I by the small pump II, squeeze into the boiler V by the water circulating pump III again, deliver to the heat supply district by the road and form the whole system circulation.The system works force value is controlled in the bound pressure limit by electro connecting pressure gauge, and the increase of the expansion of water volume or contraction, the water yield or minimizing in the system are stored and exported to pipeline by the device I.When electric contact pressure drops to threshold pression, during the system lack of water, the small pump II is subjected to electro connecting pressure gauge control beginning moisturizing automatically, and until to the upper limit pressure time, the small pump II quits work.If when system pressure surpasses electric contact upper limit pressure, can carry out pressure release by pipeline safety valve IV in the system.Pressure release water is back in the softening water tank VI, stops pressure release when reaching the upper limit pressure of system's design.Controlling pipeline between system's backwater and boiler V with paying the tube valve VII, the water inlet pipe and water outlet pipe VIII is connected to constant pressure point by design.
