Description
Technical Field
The utility model relates to a gas boiler's technical field particularly, relates to a be applied to cleaning opening of gas boiler heat exchange tube.
Background
The boiler is an energy conversion device, the energy input to the boiler comprises chemical energy and electric energy in fuel, and the boiler outputs steam, high-temperature water or an organic heat carrier with certain heat energy. The gas boiler belongs to a boiler, and comprises a gas water boiler, a gas hot water boiler, a gas steam boiler and the like, wherein the gas hot water boiler is also called a gas heating boiler and a gas bathing boiler, the gas boiler refers to a boiler using fuel gas as the name of the boiler, and the gas boiler is most economical compared with an oil boiler and an electric boiler, so most people select the gas boiler as boiler equipment for steam, heating and bathing.
The existing heat exchange tube of the gas boiler has the following problems: 1. the coil boiler is in a mosquito-repellent incense structure mode, the heat exchange tube is formed by welding longer tubes and spirally coiling the tubes, and the interior of the coil boiler can not be cleaned by water and dirt; 2. the vertical water pipe gas boiler structure is characterized in that a plurality of water pipes are arranged in a ring vertical mode, water is filled in the water pipes, the water capacity of the vertical water pipe boiler is small, the requirement on boiler water supply is high, scale is easy to form in the water pipes, the heat efficiency of the boiler is reduced due to the generation of the scale, and the pipes are exploded when serious; 3. most water pipe boilers adopt chemical mode to wash after scaling, exist and wash the dead angle clearance unclean, and whether the regional clearance of part washing reaches expected effect can't be confirmed. Even if the dead space is not cleaned after cleaning, the heat load is increased, which affects the service life and the heat efficiency of the boiler.
An effective solution to the problems in the related art has not been proposed yet.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a be applied to cleaning mouth of gas boiler heat exchange tube to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a be applied to washing mouth of gas boiler heat exchange tube, includes the tube sheet, be equipped with two circles on the tube sheet and wash the mouth, washing mouth department is equipped with the internal thread, the screw thread department threaded connection who washs the mouth has the stainless steel end cap, be equipped with the polytetrafluoroethylene gasket between the internal thread of stainless steel end cap and washing mouth.
Further, the tube plate is of a disc-type plate structure.
Further, the cleaning opening is of a tubular structure.
Further, the polytetrafluoroethylene sealing sheet has a polytetrafluoroethylene structure.
Compared with the prior art, the utility model discloses following beneficial effect has: the utility model discloses the design of washing mouth adopts threaded connection on every water pipe corresponds the center, easy installation, and it is little to take up an area of, does not influence the welding region of water pipe, adopts the stainless steel end cap on the internal thread mouth, and convenient later dismantlement of stainless steel material adopts high temperature resistant polytetrafluoroethylene gasket between end cap and the screw thread, can used repeatedly, when wasing the maintenance of heat exchange tube, need not increase the consumptive material after having dismantled the stainless steel end cap, and convenient site operation is very convenient, is fit for using widely.
