Abstract
The utility model discloses a sealing open type pipeline liquid injection part, in particular relates to a pipeline liquid injection valve. The pipeline liquid injection valve comprises a water inlet port and a first port, a second port and a valve core, wherein the first port and the second port have a consistent axis. The valve core is a ball valve core, the upper part of the valve core is provided with a combination part, a first channel and a second channel, and the first channel and the second channel correspond to a channel of the inlet port and extend along a great circle on the surface of the valve core. The two channels are perpendicular correspondingly to the great circle and extend to a tangent plane which is bigger than a tangent plane of the inlet port corresponding to the first port and the second port and smaller than an opposite tangent plane of the tangent plane. The utility model provides the pipeline liquid injection valve with compact structure, low cost and convenient use.
Description
(1) technical field
The utility model relates to a kind of sealing, open type pipeline fluid injection parts, specifically relates to a kind of pipeline fluid-delivery valve.
(2) background technique
The pipeline of airtight at present, open type generally need wash it, exhaust, topping up or suppress operation.Flushing to pipeline needs equipment to have into water and two pipelines of backwater, and for preventing that backwater from mixing mutually, water inlet and water return pipeline intermediate demand are isolated in the process of flushing simultaneously.For realizing this function, generally speaking, above-mentioned each pipeline all need be controlled respectively by ball valve or stop valve, thereby controls the break-make of each pipeline.Though this mode can realize above-mentioned functions well, but the used component of this device are many, volume ratio is bigger, and cost is than higher, and for realizing certain function, often needs to disconnect one the tunnel, connects one tunnel, at least twice valve event, the operation more complicated.A kind of special-purpose fluid-delivery valve has also appearred in addition at present, solved three ball valves or stop valve structure complexity, troublesome poeration, shortcoming that cost is high, yet its spool causes the valve body longitudinal size excessive for the valve ball or the annular groove of serial connection, design, manufacturing difficulty, cost is than higher.
(3) summary of the invention
The utility model is at present pipeline fluid-delivery valve complex structure, and defect of high cost provides a kind of compact structure, and cost is low, pipeline fluid-delivery valve easy to use.
The technical solution adopted in the utility model is:
The utility model pipeline fluid-delivery valve, comprise into water interface first interface, second interface consistent with axis, and spool, described spool is a spherical valve core, its top is provided with connecting part first passage and the second channel along spool face great circle extension corresponding with the passage of described water inlet interface, the corresponding great circle of two passages is vertical, and two passages extend to greater than first interface, second interface tangent plane corresponding to the water inlet interface, less than the relative tangent plane of this tangent plane place.
Above-mentioned pipeline fluid-delivery valve, described water intake is provided with sealing cover.
The utility model pipeline fluid-delivery valve, it is embodied in it corresponding to existing pipeline fluid-delivery valve improvements and adopts single ball valve to realize original function of passing through three ball valves or stop valve, this valve core outer surface is provided with two passages that extend along its surface, the corresponding water intake in its connecting part, and both corresponding great circles are vertical, the other end is then corresponding to first interface or second interface, when forwarding first passage to, this valve constitutes first interface and water inlet interface when being communicated with the position like this, then second channel is in the face by water inlet interface axis and this passage, and be in cut-off state, just this moment, second interface and water inlet interface were in cut-off state; Otherwise then first interface and water inlet interface are in cut-off state.The utility model spool is spherical, and its surface only is provided with two passages, is convenient to processing, and used component are few, and cost is low, compact structure.
(4) description of drawings
Fig. 1 is the utility model embodiment pipeline fluid-delivery valve structural representation.
Fig. 2 is the utility model embodiment pipeline fluid-delivery valve valve core structure schematic representation.
Among the figure: 1, first interface, 2, valve handle, 3, valve body, 4, second interface, 5, sealing cover, 6, the water inlet interface, 7, second channel, 8, first passage, 9, spool.
(5) embodiment
Specify structural principle of the present utility model below in conjunction with Figure of description:
With reference to the attached Fig. 1 and 2 of explanation, this embodiment comprises into water interface 6 first interface 1, second interface 4 consistent with axis, and spool 9, described spool 9 is a spherical valve core, its top is provided with connecting part first passage 8 and the second channel 7 along spool face great circle extension corresponding with the passage of described water inlet interface 6, the corresponding great circle of two passages is vertical, and two passages extend to greater than first interface, second interface tangent plane corresponding to the water inlet interface, less than the relative tangent plane of this tangent plane place.
Described water intake 6 is provided with sealing cover 5, and water filling finishes, and can live this water intake with the sealing cap seal.
Claims (2)
1. pipeline fluid-delivery valve, comprise into water interface (6) first interface (1), second interface (4) consistent with axis, and spool (9), it is characterized in that: described spool (9) is a spherical valve core, its top is provided with connecting part first passage (8) and the second channel (7) along spool face great circle extension corresponding with the passage of described water inlet interface (6), the corresponding great circle of two passages is vertical, two passages extend to greater than first interface, second interface tangent plane corresponding to the water inlet interface, less than the relative tangent plane of this tangent plane place.
2. pipeline fluid-delivery valve according to claim 1 is characterized in that: described water intake (6) is provided with sealing cover (5).
