Abstract
The invention discloses a multifunctional watermeter connecting valve which comprises a non-return valve (1), a filtering net (2) and a telescopic unit (3), wherein the non-return valve (1) is in flanged connection with the telescopic unit (3), the filtering net (2) is fixed at the connecting end of the telescopic unit and the non-return valve, a sewage discharging hole which is a spiral hole is arranged at the lower part of a valve body of the non-return valve (1), and a bolt (4) of the sewage discharging hole is connected and sealed by threads arranged in the sewage drain hole. The invention has good non-return effect and can discharge sewage produced by the filtering net in time.
Description
Technical field
The present invention relates to valve, connect valve before especially a kind of multifunctional watermeter.
Background technique
Equipment before the present water supply industry water meter is installed, and is made up of Swing check valve, filter and three products of expansion bend respectively.Aqueous reflux after safety check prevents to cut off the water supply in the pipeline reaches the purpose of sealing pipeline immediately, and filter filters the current of flowing through, and prevents to be mingled with in the current sandstone and destroys water meter, and expansion bend is convenient to be installed and connection.Owing to non-return weak effect during the no hydraulic pressure that original single product exists, filter the problem that dirt that the back produces but can not be discharged after installation, had a strong impact on polluting once more and working life of miscellaneous equipment of last water water source.
Summary of the invention
Equipment was installed the non-return weak effect before purpose of the present invention solved existing water meter exactly, problem that can not blowdown.
The technical solution used in the present invention is: multifunctional watermeter connecting valve, it is characterized in that it comprises safety check, filter screen and expansion bend, described safety check is connected with the expansion bend flange, filter screen is fixed on expansion bend and safety check connecting end, the valve body lower portion of described safety check is provided with pollutant exhaust hole, pollutant exhaust hole is a screw, is provided with the bolt that scyewed joint seals up pollutant exhaust hole in the pollutant exhaust hole.
Adopt technique scheme, because safety check and expansion bend are connected as a single entity, when stopping in the pipeline, safety check can in time cut out non-return, as long as unclamp bolt when the needs blowdown, sewage draining exit is opened, and can realize blowdown.
Beneficial effect of the present invention is: safety check can cut out rapidly when cutout, and non-return is effective; The safety check below is provided with sewage draining exit, and therefore the dirt that can in time produce filter screen is discharged.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure, 1, safety check, 2, filter screen, 3, expansion bend, 4, bolt.
Embodiment
Multifunctional watermeter connecting valve of the present invention, as shown in Figure 1, it comprises safety check 1, filter screen 2 and expansion bend 3, described safety check 1 is connected with expansion bend 3 flanges, filter screen 2 is fixed on expansion bend and safety check connecting end, the valve body lower portion of described safety check 1 is provided with pollutant exhaust hole, and pollutant exhaust hole is a screw, is provided with the bolt 4 that scyewed joint seals up pollutant exhaust hole in the pollutant exhaust hole.
