Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-4, the pressure relief device of the gas heating water heater of the utility model comprises a pressure relief body 1, a pressure relief core 2 and a pressure relief cover 3, wherein the right part of the pressure relief body 1 is arranged in a convex shape, the left part of the pressure relief body 1 is provided with threads and is connected with the gas heating water heater through threads, a plurality of anti-skid threads are arranged at the protruding parts on the pressure relief body 1, and when the pressure relief device is installed, the protruding parts of the pressure relief body 1 are held by hands, and then the pressure relief body 1 is installed on the gas heating water heater in a rotary mode through the threads.
The inside of pressure release body 1 is provided with logical groove 4 to the left part is the taper setting, and the middle part of relief cap 3 is provided with the spout, and pressure release core 2 sliding connection is in the spout, and the right part of logical groove 4 is provided with the screw thread, and pass through threaded connection between with the relief cap 3, the right part of relief cap 3 is six prismatic settings, thereby when adorning relief cap 3 on pressure release body 1, thereby be fixed in relief cap 3 on pressure release body 1 through rotatory relief cap 3 right part, thereby the relief cap 3 of hexagonal prism dress can prevent to rust between relief cap 3 and the pressure release body 1, if be difficult to unscrew relief cap 3, just accessible spanner unscrews relief cap 3.
The left part of pressure release core 2 is provided with keeps off ring 5 to install spring 6 between with relief cap 3, the left end of pressure release core 2 supports in the left portion taper department of logical groove 4, and the middle part and the right part of pressure release core 2 are provided with several exhaust groove 7, and exhaust groove 7 is circular-arc setting in the side of pressure release body 1, and circular-arc exhaust groove 7 does not have the clearance dead angle, and is more convenient relatively washs.
When the air pressure in the gas heating water heater is overlarge, the pressure forces the pressure release core 2 to move rightwards against the elasticity of the spring 6, at the moment, water vapor can enter the through groove 4 through a gap between the pressure release core 2 and the through groove 4, and then the water vapor is discharged out of the pressure release body 1 at the position of the exhaust groove 7, so that the pressure release device has a good pressure release effect, and when the pressure in the gas heating water heater is less than the elasticity of the spring 6 to the thrust of the pressure release core 2, the pressure release core 2 can block the through groove 4, so that the water vapor can not pass through any more.
When the pressure release core is used, the weight of the pressure release core 2 can influence the movement of the pressure release core 2 to a certain extent, so that the pressure release core 2 is smaller in weight, the inside of the pressure release core 2 is hollow, and the weight of the pressure release core 2 is reduced.
To sum up, when cleaning, the pressure release device of the gas heating water heater firstly removes the pressure release body 1, then unscrews the pressure release cover 3 on the pressure release body 1, at this time, the pressure release body 1, the pressure release core 2, the spring 6 and the pressure release cover 3 are separated, then cleaning the pressure release body 1, the pressure release core 2 and the pressure release cover 3 one by one, after cleaning, the spring 6 is sleeved on the pressure release core 2, then the pressure release core 2 is inserted into the pressure release cover 3, finally the left part of the pressure release cover 3 is upwards placed, and the pressure release body 1 is screwed between the lower part of the upper part of the pressure release cover 3 and the pressure release cover 3.
