Abstract
The utility model relates to a nonpressure operating controller for a hot water boiler, which is composed of a valve body, a strainer, a valve chamber, and a valve clack. The utility model is characterized in that a compression spring for regulating the opening degree of the valve clack is arranged above the valve body. A press block and a regulation screw are arranged above the compression spring. The utility model has the advantages that the nonpressure operation of the hot water boiler can be realized if the nonpressure operating controller for a hot water boiler is arranged on the return general line of the hot water boiler. Modification is not required to be implemented for a pressure hot water boiler. Thus, the nonpressure operation with inner pressure no greater than 0.1 mpa of the hot water boiler can be realized and ensured. The nonpressure operating controller for a hot water boiler is suitable for the pressure hot water boiler for matching use.
Description
The utility model belongs to the nothing of the fluid heater that heat-generating device is arranged, particularly a kind of water-heating boiler and presses operation controller.
At present, water-heating boiler is in service, and the pressure that hydrostatic pressing and hot water circuit produced of heating system can cause that the boiler internal pressure increases, and makes the boiler band press operation, and the danger of blast is arranged.The existing technological scheme that solves is to have the UNICOM's mouth that is connected with atmosphere at the top of water-heating boiler drum, and adorn a recovery tank, in establish float valve, work under the barometric pressure, safety check is installed, will have the water-heating boiler of pressure to repack unpressurized hot water boiler's operation in the outlet port of circulating water pump.This method of modifying, though realized safe operation,, increased manufacture cost.
The purpose of this utility model is that being provided with one on the return pipe that the pressure water-heating boiler is arranged does not have the operation controller of pressure, realizes the adjusting to the water-heating boiler internal pressure, effectively prevents the generation of the bursting of boilers, accomplishes the safe operation of pressing water-heating boiler.
Water-heating boiler of the present utility model does not have the pressure operation controller, is made up of valve body, filter screen, valve chamber, flap, it is characterized in that, is provided with the pressure spring of regulating the flap opening degree above flap, is provided with briquetting and adjusting screw rod above pressure spring.
Working principle of the present utility model is that hot water enters hot water cyclesystem through filter screen, valve chamber, relies on hot water circulating pump to drive flowing of hot water; To press operation controller is the open type spring because water-heating boiler does not have, and downstream pressure can be set up, and when the pressure that hot water circuit produced, by the change mouth that dams, pressure is eliminated in the build-up of pressure loss, is in the state that does not have the operation of pressing thereby reach the control water-heating boiler.The opening degree of pressure spring can regulate flap, the flow size of set pressure and hot water.
Water-heating boiler of the present utility model does not have the pressure operation controller, have the following advantages: only need that water-heating boiler is not had the operation controller of pressure and be installed on the return main of water-heating boiler, can realize the nothing pressure operation of water-heating boiler, the volume of controller is little, in light weight, Installation and Debugging are convenient, and are safe and reliable to operation; Needn't transform the water-heating boiler of pressure is arranged, can realize, guarantee that the water-heating boiler internal pressure is not more than 0.1MPa, make and pressed water-heating boiler to realize not having the operation of pressure.Be applicable to and pressed supporting use on the water-heating boiler.
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is that water-heating boiler does not have the tectonic maps of pressing operation controller
As seen from the figure, water-heating boiler does not have the pressure operation controller, is made up of valve body 1, filter screen 2, valve chamber 7, flap 3, it is characterized in that, above flap 3, be provided with the pressure spring 5 of regulating flap opening degree set pressure, above pressure spring, be provided with briquetting 4 and adjusting screw rod 6.
