Description
The utility model relates to the fluid-duct-system stable-pressure device, particularly a kind of heat supply ductwork stable-pressure device.
The pipe-line system that one class heat supply water is arranged in the modern architecture heating of house device.Mainly comprise elevated tank, expansion tank, boiler and be connected water pipe, they constitute closed circuit hot water cyclesystem with hot water dispenser, water circulating pump and heat exchanger, heat exchanger have wall, coil pipe and radiator forms such as (hot water spits of fland), can heat to indoor heating.Also can constitute the water system of open circuit with hot and cold water nozzle, conveyance conduit, provide wash the dishes, wash one's face and rinse one's mouth, life such as washing is with hot water and cold water (seeing accompanying drawing 1).In the said system: elevated tank and expansion tank can provide or replenish cold water, eliminate the overvoltage phenomenon in the circulating hot water system to heating system, play safety, voltage stabilizing; Boiler provides hot water; Water pump drives hot water circuit; Hot water dispenser then connects each road heat exchanger.Because the volume of elevated tank and expansion tank is bigger, and need be installed in higher position in the above-mentioned heat supply ductwork, drop than the people be arranged in the hope of water level.And the floor height of residential housing at present is generally lower, generally about 2.7 meters, therefore select the installation position of elevated tank and expansion tank to be equipped with very big difficulty, and the number of tubes of whole heat supply ductwork is big, tie point is many, cost height not only, installation, maintenance, use also very inconvenient.
The purpose of this utility model is the stable-pressure device that a kind of alternative elevated tank and expansion tank will be provided.Use not only heat supply with security and stability, the water supply of heat supply ductwork of this stable-pressure device, and heat supply ductwork is simplified and is suitable for low floor height dwelling house and uses.
Task of the present utility model is finished as follows.
A kind of heat supply ductwork stable-pressure device, has housing, its characteristics are that described lower housing portion is provided with water inlet, delivery port, is located at described water inlet bottom line following spout hole, housing top and is provided with passage, be provided with interface channel between described delivery port and the housing intracavity bottom, described housing inner chamber is sequentially with piston, spring and the spring attachment of band cavity, and described housing upper end is connected with cap.
Housing one side of the utility model stable-pressure device can be connected with safety valve, described safety valve comprises valve body, be located at the above passage of bottom line on the delivery port, described valve body inner chamber has been sequentially with spool, spring and spring attachment, and described valve body upper end is connected with valve gap.
The spring attachment of the new stable-pressure device of this practicality can be by spring base, align screw and the nut that is fixed on the cap is formed.
The spring attachment of the utility model stable-pressure device can comprise the jacking block that is located in the described cap, and described cap and housing are with being threaded.
The spring attachment of the utility model stable-pressure device can comprise the one group of pad that is pressed on the described spring, and described cap and housing are with being threaded.
After the utility model stable-pressure device inserts heat supply ductwork, set the pressure of stable-pressure device delivery port with spring attachment.During the heat supply ductwork operation, if the pressure of stable-pressure device delivery port descends, then the piston in the stable-pressure device descends, and when the cavity in the described piston communicated with entery and delivery port, running water flowed into heat supplying pipeline by water inlet, piston cavity and delivery port.Finish when cold water replenishes, when the boiler heating is expanded hot water, the heat hydraulic pressure through the communication channel of housing bottom with piston jack-up and stop running water to enter.When the heat hydraulic pressure further improves, surpasses predefined delivery port pressure, carry, expose the spout hole on the housing on piston is further, hot water reaches the decompression purpose by the spout hole discharge, therefore stable-pressure device of the present utility model has automatically additional running water, the function of discharging overvoltage hot water can guarantee the safe operation under the delivery port pressure condition of setting of whole heating system.Compared to the prior art, behind alternative elevated tank of stable-pressure device and expansion tank, the structure of heat supply ductwork is simplified, connecting pipe reduces, and brings convenience to installation, maintenance.The volume of the utility model stable-pressure device has only the 1/30-1/100 of elevated tank and expansion tank volume, and installation site and pressure of supply water are not had specific (special) requirements, and safe and reliable.
