Abstract
The utility model discloses a safety blocking pressure adjusting device for a warming device. The lateral wall of a buffer tank is provided with a water inlet pipe and a water outlet pipe which extend into a tank cavity. A water inlet valve is arranged on the water inlet pipe, a pressure adjusting valve rod is arranged on the water inlet valve, the pressure adjusting valve rod extends out of the buffer tank through a valve sleeve, and a pressure adjusting hand wheel is arranged at the upper end of the pressure adjusting valve rod. A water outlet valve is arranged on the water outlet pipe, the water outlet valve is fixedly connected with a piston through an ejection rod, a piston tube is arranged on the buffer tank, and the tail end of the piston tube is communicated with a warming water feeding pipeline. An exhaust valve is arranged at the upper end of the buffer tank. The safety blocking pressure adjusting device is reasonable in design, compact in structure and low in cost, has a back-sucking-proof stop function, an exhaust function and a pressure adjusting buffering function, is favorable for installation, management and maintenance and further has remarkable practicability.
Description
Technical field
The utility model relates to heating equipment field, relates in particular to a kind of heating equipment and blocks safely regulator.
Background technology
In highrise heating system technology, hot water is through enough just supplying with user terminal after pressurization, and water return pipeline pressure is excessive, the city planting ductwork of must being allowed for access after decompressor cushions; Meanwhile, because highrise heating system drop is larger, siphonage is obvious, and when city planting ductwork is cut off the water supply, the water in pipeline easily refluxes, and causes blank pipe phenomenon, even terminal heating equipment is damaged, and need add the generation that anti-suck block device carrys out anti-backflow situation.In addition, for preventing that in heating pipe network, gas occurring blocks up, and need add means of deflation.Above-mentioned decompressor, anti-suck block device and means of deflation are generally independent device, need purchase respectively, install, and cost is higher on the one hand, and operation comparatively bothers on the other hand, are unfavorable for installing and safeguarding.
Utility model content
For overcoming prior art deficiency, the utility model provides a kind of scientific structure design, anti-suck block function, degassing function and pressure regulation buffer function are incorporated into one, can effectively reduce costs, and be conducive to install and the heating equipment of management maintenance is blocked safely regulator.
For realizing above-mentioned technical purpose, the utility model by the following technical solutions: a kind of heating equipment is blocked safely regulator, comprises a surge tank, and the sidewall of surge tank is provided with water inlet pipe and the outlet pipe extending in tank chamber; Water inlet pipe is provided with the water intaking valve of controlling itself and tank chamber connected state, water intaking valve is provided with pressure regulation valve rod, pressure regulation valve rod extends surge tank by a valve pocket, the upper end of pressure regulation valve rod is provided with regulating hand wheel of pressure, valve pocket is fixed on surge tank, and upper end is fixed with swivel nut, pressure regulation valve rod is provided with the screw thread coordinating with this swivel nut; Described outlet pipe is provided with controls itself and the outlet valve of tank chamber connected state, and outlet valve is fixedly connected with a piston by a push rod, and surge tank is provided with a piston cylinder coordinating with piston, and piston cylinder tail end is communicated with the watering pipeline that heats; Described surge tank upper end is provided with air bleeding valve.
The utlity model has following beneficial effect: high pressure backwater, is reduced pressure by water intaking valve by water inlet pipe in water intaking valve enters surge tank, and under surge tank cushioning effect, obtain the mild current of low pressure, finally by outlet valve, by outlet pipe, enter municipal heating pipe network.By the opening of the adjustable water intaking valve of regulating hand wheel of pressure, play the object of pressure regulation; By air bleeding valve, the gas coming together in surge tank can be discharged, guarantee that heating pipeline is smooth and easy; Because outlet valve is controlled opening by the hydraulic pressure in the watering pipeline that heats, therefore when heating equipment is out of service, outlet valve is closed, and then play the effect that anti-suck is blocked.The utility model is reasonable in design, and compact conformation is with low cost, has anti-suck block function, degassing function and pressure regulation buffer function, is conducive to install and management maintenance, and then has significant practicality.
