CN2401832Y - Safety wind-proof cap for gas water-heater - Google Patents

Abstract

The utility model relates to a safety wind-proof cap for a gas water heater, which comprises an outside cover, a gas cylinder, a wind screen and connecting plates. The gas cylinder is connected with a draught flue of a water heater; the wind screen prevents strong wind from pouring in the draught flue of the water heater; the gas cylinder, the wind screen and the outside cover are connected by a plurality of the connecting plates. The wind screen is arranged under the position of ventilating holes in the outside cover to cause the flue gas of the safety wind-proof cap for a gas water heater to bypass the wind screen; the gas cylinder passing through the space between the wind screen and the outside cover is arranged under the wind screen; a plurality of connecting plates are fixed with the outside cover; the wind screen and the gas cylinder are respectively fixed with a plurality of connecting plates. The utility model can eliminate the accident threat because of the unsafety of the gas water heater.

Description

Gas heater safety is prevented blast cap

The utility model relates to the anti-blast cap of a kind of gas heater safety.

Big capacity (more than the 6.5 liters) gas heater of selling on the domestic market is in normal use at present, because the water heater burning is insufficient, residual micro CO and other pernicious gas in the useless flue gas that the burning back is discharged, outside the drain chamber, the personnel casualty accidents that causes thus takes place throughout the country repeatedly timely and effectively.

The purpose of this utility model is to overcome the deficiency of above-mentioned technology, provide a kind of gas heater safety to prevent blast cap, when the gas heater exhaust gas discharged arrives this blast cap by flue, the normal discharge capacity that can guarantee waste gas effectively is discharged in the outside atmosphere by blast cap, control high wind simultaneously and pour flue into, thereby eliminate gas heater because the dangerous accident potential that brings.

The purpose of this utility model realizes by following technical proposals:

A kind of gas heater safety is prevented blast cap, has outer cover, the gas cylinder that is connected with the exhaust uptake of water heater, along the circumferential direction be distributed with a plurality of air vents on the described outer cover top exterior walls, its technical scheme is that it also has and prevents that high wind from pouring the deep bead of water heater exhaust uptake into, several connecting plates that gas cylinder and deep bead and outer cover are connected, deep bead is located at the following position of outer cover inner vent, making flue gas in it walk around the gas cylinder that deep bead passes through between deep bead and outer cover inwall is located at below the deep bead, several connecting plates and outer cover are affixed, deep bead, gas cylinder respectively with several connecting plate Joints.

Compared with prior art, the utlity model has following advantage:

1. the top portion ventilation hole of outer cover can 360 ° of dischargings, when wind from any one direction by the time, according to the air force venturi principle, can make the local negative pressure that produces of outer cover inner top, strengthen draft.

2. deep bead is housed in outer cover, when guaranteeing normal discharging, can prevents that high wind from pouring the exhaust uptake of water heater into.During the water heater normal combustion, exhaust gas discharging speed 2.5 meter per seconds can produce certain speed by flue and discharge by blast cap, thereby eliminate gas heater because the dangerous accident potential that brings.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 be among Fig. 1 A to view.

As Fig. 1, shown in Figure 2, the utlity model has outer cover 1, the gas cylinder 4 that is connected with the exhaust uptake of water heater, prevent that high wind from pouring the deep bead 2 of water heater exhaust uptake into, several connecting plates 3 that gas cylinder 4 and deep bead 2 and outer cover 1 are connected, along the circumferential direction be distributed with a plurality of air vents 11 on described outer cover 1 top exterior walls, deep bead 2 is located at the position of outer cover inner vent below 11, making flue gas in it walk around the gas cylinder 4 that deep bead passes through between deep bead and outer cover inwall is located at below the deep bead 2, several connecting plates 3 are affixed with outer cover 1, deep bead 2, gas cylinder 4 respectively with several connecting plate 3 Joints.Connecting plate 3 can be provided with 3.

Claims (2)

1. a gas heater safety is prevented blast cap, has outer cover (1), the gas cylinder (4) that is connected with the exhaust uptake of water heater, along the circumferential direction be distributed with a plurality of air vents (11) on described outer cover (1) top exterior walls, it is characterized in that it also has prevents that high wind from pouring the deep bead of water heater exhaust uptake (2) into, several connecting plates (3) that gas cylinder (4) and deep bead (2) and outer cover (1) are connected, deep bead (2) is located at the following position of outer cover inner vent (11), making flue gas in it walk around the gas cylinder (4) that deep bead passes through between deep bead and outer cover inwall is located at below the deep bead (2), several connecting plates (3) are affixed with outer cover (1), deep bead (2), gas cylinder (4) respectively with several connecting plates (3) Joint.

2. gas heater safety according to claim 1 is prevented blast cap, it is characterized in that connecting plate (3) can be provided with 3.
