Abstract

The pressure-bearing type water with decompression function is chewed, sealed by main body 2, handle 3, ceramic plate that water chews 4, pressure relief device 10 is formed, when water chews closedown, water heater is sealed type bearing structure, if temperature limit switch is malfunctioning in water tank liner, electric heating tube constantly heats, the pressure of water tank liner can be more and more higher, when reaching setting pressure, pressure relief device 10 can open relieving pressure automatically, and is communicated with air by gondola water faucet.

Description

The pressure-bearing type water with decompression function is chewed

Technical field

The present invention relates to the storage-type electric water heater water with decompression function to chew.

Background technique

Existing storage-type electric water heater water used is chewed (or claim mixed water valve, and lower same) be all sealed type pressure-bearing type structure, the handle chewed of namely fetching boiling water, the gondola water faucet of water heater discharges water immediately, close the handle that water is chewed, just stop discharging water, make the water tank of water heater become sealed type bearing structure; Chew handle when water to close, in water-heater water tank, electric heating tube is in heating, and water tank internal pressure will be made constantly to raise, if temperature limit switch is malfunctioning, electric heating tube constantly heats, and the pressure in water tank can continue to raise, until water tank blast damages.

Summary of the invention

The present invention chews the seal and pressure bearing formula water that existing storage-type electric water heater uses and improves, and makes it have decompression function.

Water is chewed 1 and is chewed 4 formed by main body 2, handle 3, ceramic plate sealing water, and water is chewed in main body 2 three water inlet and outlet interfaces, and the cold water pipe interface 2/1 be connected with water source manages with tank hot water the interface of hot water 2/2 be connected, the mixing water interface 2/3 be connected with gondola water faucet; It is characterized in that:

Two holes are had in hot water outlet 2/2, one is the hot water channel 2-5 directly communicated with water tank liner, the pressure relief device 10 exceeding setting working pressure and can automatically open also is installed in the 2-6 of hot water outlet mouth 2/2, after opening, makes it be communicated with air by gondola water faucet.

Described pressure relief device 10 is by sealing gasket 10-1, and mandrel 10-2, spring 10-3 are formed.

Advantage of the present invention makes originally to chew for seal and pressure bearing formula water, is provided with and exceedes setting pressure, can automatically open and communicate with air, improve the Safety performance of electric water heater.

Embodiment

Be described below in conjunction with accompanying drawing, the pressure-bearing type water in accompanying drawing with decompression function chews 1, and main body 2 (in main body 2, cold water pipe interface 2/1, interface of hot water 2/2, be connected with gondola water faucet, mixing water interface 2/3, ceramic plate sealing water chews 4 installation cavitys 2/4), handle 3, ceramic plate sealing water chews 4, main body 2 is arranged 6 holes (hole 1, hole 2, hole 3, hole 4, hole 5, hole 6), pressure relief device 10 (wherein sealing gasket 10-1, mandrel 10-2, spring 10-3).

Fig. 1 is the outline drawing that the pressure-bearing type water with decompression function chews 1, by main body 2, handle 3 (shown in Figure 4), ceramic plate sealing water chews 4 compositions, main body 2 has the chamber 2-4 that ceramic plate sealing water chews 4 is installed, 3 interfaces also, cold water inlet 2/1, hot water outlet 2/2 and blend the mouth of a river (i.e. gondola water faucet mouth) 2/3, it is characterized in that: in hot water outlet 2/2, apart from outside the hot water channel hole 5 directly communicated with water tank liner, also in 2/2 interface (hole 6), be provided with exceed setting working pressure can self-relieving device 10.

Fig. 5 to Fig. 8 is several views of main body 2, Fig. 5 is graphics, Fig. 6 is the plan view of Fig. 5, Fig. 7 is the sectional view of the A-A of Fig. 8, Fig. 8 is the sectional view of the B-B of Fig. 7, to it is characterized in that in main body 2 porose 1, hole 2, hole 3 (shown in Fig. 6 position), hole 4, hole 5, hole 6 (shown in Fig. 7 position) is totally 6 holes, hole 1 communicates with hole 4, enter cold water, and passing hole 2 or be cold water pipe interface 1/2, hole 3 communicates with hole 5 (hot water flows into), hole 6 communicates (relieving pressure) with hole 4, wherein there are two holes in hot water outlet 2/2, one is the hole 5 directly communicated with water tank liner, another is the hole 6 of installing pressure relief device 10, when water chew 1 open time (2/2 at open position), the water in water tank, after passing hole 5 enters ceramic plate sealing water chews 4 mixing, flows out from mixing water water outlet 2/3 through 1 → hole, hole 4, if when water chews 1 closedown, water tank liner is exactly seal container, if temperature limit switch is malfunctioning in water tank liner, electric heating tube heats for a long time, and the pressure of water tank liner is constantly increased, and when reaching setting pressure, hot water can flow out from the osculum 6 of the pressure relief device 10 be arranged on 2/2, relieving pressure.

Pressure relief device 10, can be made into stand-alone assembly, then is pressed in hot water mouth 2/2.
