Abstract
The utility model discloses an injection valve for sealed pipe, which belongs to the field of injection parts for sealed pipe; the structure comprises a water inlet ball valve, a water return ball valve and a main ball valve; the main ball valve is arranged at the upper part of the valve; the water inlet ball valve and the water return ball valve are arranged on both sides at the lower part of the valve; the water inlet ball valve, the water return ball valve and the main ball valve form a delta on the valve. Compared with the prior art, the injection valve for sealed pipe of the utility model is characterized by reasonable design, simple structure, convenience in operation, low production cost, etc., and can meet pressure pumping and liquid filling requirements for sealed circulating pipes.
Description
Technical field
The utility model relates to a kind of airtight pipeline fluid injection parts, specifically a kind of airtight pipeline fluid-delivery valve.
Background technique
At airtight pipeline, generally need wash it, exhaust, towards liquid or suppress operation.Flushing to pipeline needs equipment to have into water and two pipelines of backwater, simultaneously for to prevent into/and backwater is blended in the process of flushing water inlet and water return pipeline intermediate demand mutually isolates.
Generally speaking, this function need realize by three ball valves or stop valve, and ball valve or stop valve are installed on the main line of airtight pipeline, play by effect; In addition two ball valves or stop valve are installed on the pipeline at two ends of above-mentioned ball valve or stop valve, play the into shutoff effect of water, backwater.Though this mode can realize above-mentioned functions, complex structure, troublesome poeration, cost are higher.
Summary of the invention
Technical assignment of the present utility model is at above deficiency, provide a kind of simple in structure, cost of production is low, be easy to process, a kind of airtight pipeline fluid-delivery valve easy to use.
The technological scheme that its technical problem that solves the utility model adopts is: this fluid-delivery valve comprises water intake ball valve, backwater ball valve and cue ball valve, the cue ball valve is arranged on the top of valve body, water intake ball valve and backwater ball valve are arranged on the both sides of valve body lower portion, and water intake ball valve, backwater ball valve and cue ball valve are the Pin Zixing setting on valve body.
The cue ball valve plays the effect in open/close system loop.And two small balls, one is water intake ball valve, another is the backwater ball valve.When system was cleaned, the cue ball valve was in closed condition, and water intake ball valve, backwater ball valve are in opening state, and liquid advances from water intake ball valve by power, behind the whole closed system of flowing through, discharged from the backwater ball valve; Cleaning the back and change liquid, closed system is carried out exhaust, is that the cue ball valve is in closed condition equally, and water intake ball valve, backwater ball valve are in opening state, does not have bubble up to the backwater ball valve and discharges, and illustrates that closed system has not had gas; Carry out system's fluid injection then, cue ball valve, backwater ball valve are closed at this moment, and water intake ball valve is opened, and by power liquid is injected in the closed system, closes water intake ball valve then, opens the cue ball valve, promptly finishes system's fluid injection.
Described airtight pipeline fluid-delivery valve, its water intake ball valve and backwater ball valve are provided with sealing cover.
Fluid-delivery valve is the important composition assembly of closed system, mainly plays cleaning, exhaust, fluid injection.Thereby, be used for airtight pipeline cleaning, suppress with fluid injection especially solar water-heating system and have wide market application prospect and excellent popularization use value.
A kind of airtight pipeline of the present utility model is compared with prior art with fluid-delivery valve, has characteristics such as reasonable in design, simple in structure, easy and simple to handle, that cost of production is low, and that has satisfied the sealing and circulating pipeline suppresses the topping up requirement.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is the structural representation of a kind of airtight pipeline with fluid-delivery valve.
Among the figure: 1, water intake ball valve, 2, the backwater ball valve, 3, the cue ball valve, 4, valve body, 5, sealing cover.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
A kind of airtight pipeline fluid-delivery valve of the present utility model, its structure comprises water intake ball valve 1, backwater ball valve 2 and cue ball valve 3, fluid-delivery valve valve body 4 materials are lead brass.Cue ball valve 3 is arranged on the top of valve body 4, and water intake ball valve 1 and backwater ball valve 2 are arranged on the both sides of valve body 4 bottoms, and water intake ball valve 1 and backwater ball valve 2 are provided with sealing cover 5, and water intake ball valve 1, backwater ball valve 2 and cue ball valve 3 are the Pin Zixing setting on valve body 4.
The fluid-delivery valve two ends connect the pipeline of medium circulation system.When practical operation was used, water intake ball valve 1 and backwater ball valve 2 were interchangeable.
A kind of airtight pipeline of the present utility model is very simple and convenient with its processing and fabricating of fluid-delivery valve, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characteristics of specification, be the known technology of those skilled in the art.
