Description

The gas heater attemperating unit

The utility model relates to a kind of attemperating unit, a kind of specifically gas heater attemperating unit.

Water heater on the market has gas heater now, electric heater and solar water heater three major types, gas heater is fast because of its hot water, water outlet is continuous, and low price is subjected to many consumers and welcomes, but there is a common deficiency in gas heater, to be exactly water temperature with the variation of hydraulic pressure change that (that is: water temperature reduced when hydraulic pressure raise for that, water temperature raise when hydraulic pressure descended), because there is the unstable phenomenon (especially in the water use peak phase) of hydraulic pressure in the many cities of China, thereby cause water temperature fluctuated, people need not stop to adjust hot water pipe and obtain required water temperature, not only inconvenient, and be difficult for being transferred to ideal.

The utility model purpose is to provide a kind of constant gas heater attemperating unit of water temperature that makes former setting under the situation of variation in water pressure.

The purpose of this utility model realizes in the following manner: gas heater attemperating unit, its attemperating unit be by valve body 15, and valve body 15 loam cakes 13 are formed a cavity, and this cavity is divided into two Room up and down by the rubber diaphragm 31 that is positioned among the cavity: air chamber and hydroecium; On the rubber diaphragm 31 or under a stressed dish 7 is arranged; One rotatable handles 10 is arranged at air chamber top, and handle has a steel ball 11 for 10 times, and steel ball 11 joins with spring pipe box 9, and a pressure regulation spring 12 is arranged in the pipe box 9, and pressure regulation spring 12 is connected with stressed dish 7 by pad 6, has a pore 24 on the air chamber; Both sides have a water inlet 18 and water delivering orifice 2 respectively under the hydroecium, and a plug 3 is arranged on the water inlet 18, and plug 3 is contained on the lever 4, and lever 4 is installed on the bearing 17 by pivot pin 16 and connected vertical rod 5 is connected with stressed dish 7; Between valve body 15 outsides and loam cake 13 outsides hydraulic pressure regulation device is housed also, this device is made up of water inlet 23, water delivering orifice 14, check valve 22, pressure spring 1, steel ball 20, screw press 19, water inlet 23 and water delivering orifice 14 vertical connections, its vertical connection partly has a pressure spring 21, check valve 22 is positioned at water inlet 23 and can contacts with pressure spring, the screw press that the pressure spring opposite side has a steel ball 20 and joins with steel ball 20.

The utility model is realized the purpose of temperature constant by the flow of control water, make gas heater more convenient suitable, the utility model is simple in structure, easy to install, and need not existing water heater is transformed, just can realize the temperature of existing water heater is controlled as long as it is installed on the inlet and outlet pipe lines of water heater.

The utility model content is described in detail in detail with reference to the accompanying drawings.

Fig. 1 is the utility model facade view.

Fig. 2 looks up half-twist figure for the utility model Figure 1A-A.

Fig. 3 is the utility model attemperating unit work synoptic diagram.

With reference to Fig. 1, this device is formed two chambers up and down by valve body 15, rubber diaphragm 31, valve upper cover 13: air chamber, hydroecium.Tap water enters valve body 15 inside by the slit of water inlet 18 by valve body 15 and plug 3, enters gas heater by pipe adapter 2 then.When the pressure of tap water was constant, the slit between valve body 15 and the plug 3 (area of promptly intaking) can not change, and inflow and aquifer yield are also constant.If tap water pressure increases, the chamber pressure of valve body 15 also increases, and stressed dish 7 suffered general pressures (pressure) increase, will upwards expand, compression pressure regulation spring 12 drives on vertical rod 5 and the lever 4 stressed dish 7 and moves, and by bearing pin 16 and bearing 17 plug 3 is moved down, thereby reduce the slit (area of promptly intaking) of water inlet, inflow and aquifer yield are remained unchanged.

On the contrary, when the pressure of tap water reduces, the stagnation pressure reduction that stressed dish 7 is subjected to, pressure lower stress dish 7 at pressure regulation spring 12 moves down, and promotes vertical rod 5 and lever 4 and moves down, and by bearing pin 16 and bearing 17 plug 3 is raise, increased the gap of water inlet, guaranteed that inflow is constant.

When tap water pressure reduces to 0.06Mpa when following, at this moment the output of water pipe certainly will make water temperature raise much smaller than the water yield of the former setting of gas heater, and the utility model will inject cold water at this moment automatically and lower the temperature and keep temperature constant in hot-water line.1 describe again in conjunction with the accompanying drawings: when tap water pressure is higher than 0.06Mpa, the hydraulic pressure that enters water inlet 23 is closed check valve 22, water is cut off, when the hydraulic pressure that enters water inlet 23 during less than 0.06Mpa, check valve 22 is opened under the effect of pressure spring 21, water enters pipe adapter 14 by check valve 22, injects in the hot-water line to guarantee the constant of water temperature.It is that pressure by screw press 19 is adjusted pressure spring 21 is realized that the size of the water yield and check valve 22 are closed under much hydraulic pressure.

With reference to Fig. 2, when the pressure of tap water was higher than 0.06Mpa, check valve 22 cut out, and tap water enters in the water heater 30 through main valve 25, three-way pipe 26, pipe adapter 18, the pipe adapter 2 among Fig. 2.When hydraulic pressure is lower than 0.06Mpa, check valve 22 is pushed open by stage clip 21, just have a certain amount of tap water this moment and flow into three-way pipes 27 through three-way pipe 26, pipe adapter 23, pipe adapter 14 and converge, reaching, thereby realize the purpose of constant temperature the replenishing and cooling of flow with hot water.

Handle 10 is the pressure that is used for adjusting 12 pairs of diaphragms 31 of spring, and the big more discharge of this pressure is just big more, otherwise discharge diminishes.The utility model is contained in the bathroom, so the adjustment water yield and temperature are very convenient, after adjusting, the utility model can be temperature automatically controlled.Pogo barrel 9 among Fig. 1 be used for to the location of spring 12 with the contacting of steel ball 11, the rotation of handle 10 directly is pressed on the steel ball 11 and passes to pogo barrel 9 by steel ball 11 again, pass to spring 12 by sleeve pipe 9 again, so just significantly reduced friction, thereby spring is not subjected to torsion.Be provided with pad 6 above rubber diaphragm, the effect of this pad 6 has two, and the one, allow spring 12 directly not contact with rubber diaphragm 31, in order to avoid diaphragm 31 is broken, and the 2nd, as the pad of joint bolt 8.Have pad that the protection of stressed dish 7 is arranged for 6 times on the rubber diaphragm 31, so diaphragm 31 stressed evenly unlikely breaking, the main effect of diaphragm 31 is sealed valve bodies 15, and the hole 24 among Fig. 1 is to be used for UNICOM's atmosphere, is convenient to move on the diaphragm 31 be not subjected to resistance.Fixed head 1 is to be used for this device is fixed on the body of wall in the bathroom among Fig. 1.

With reference to Fig. 3, the utility model 29 is contained on the inlet channel 23 of water heater 30, and two water inlets of this

device

18,23 are connected with running water pipe by threeway 26,

25 are water valve from the beginning, and the

water outlet

2,14 of this device is communicated with water heater hot-water rising pipe 23 by threeway 27,

28 is fluffy for bathing, and when hydraulic pressure was normal or bigger than normal, tap water advanced from water inlet 18 through threeway 26, and water delivering orifice 2 goes out through water inlet pipe 32 to inject in the water heater, flows through threeway 27 to bathing fluffy 28 from hot-water line 33; When hydraulic pressure was on the low side, once current, tap water also advanced from water inlet 23 by threeway 26 except above-mentioned, and water delivering orifice 14 goes out, and is added in the hot-water line 33 by threeway 27.
