Abstract
The utility model relates to an adjustable pressure-reducing valve with filter, which comprises a screw, a clamp nut, a spring seat, a spring, a valve seating, a pressure plate, a rubber diaphragm, a sealing gasket, a valve body and a valve clack. The utility model is characterized in that a filter is arranged near entrance in the interior of the valve body. The utility model has the advantages of simple and reasonable structure and convenient installation and operation, and cna guarantee water quality flowing across the valve body pure. The utility model has accurate and adjustable outlet pressure, and is suitable for water supply systems in houses and industries.
Description
The utility model relates to a kind of reduction valve, particularly a kind of band filter adjustable pressure-reducing valve.
Existing adjustable pressure-reducing valve installs a filter additional owing to higher to water quality requirement in the pipeline of former capital before inlet, be used for the impurity of filtered water.But when being installed in pipeline, use article such as the rope made of hemp, adhesive tape, enter reduction valve so can produce foreign material equally because of filter.
The purpose of this utility model is to provide a kind of packs filter in the valve body into, thereby can guarantee the band filter adjustable pressure-reducing valve that water quality is pure.
The purpose of this utility model can reach by following measure: the utility model comprises adjusts screw, tightening nut, spring seat, spring, valve seat, pressing plate, diaphragm of rubber, sealing gasket, valve body, flap, it is characterized in that: in the nearly ingress of valve inner filter is housed.
The purpose of this utility model can also reach by following measure: filter is fixed on ingress in the valve body by nut.
Structure sectional view when Fig. 1 is in working state for the utility model;
Structure sectional view when Fig. 2 is in closed condition for the utility model.
The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):
With reference to Fig. 1, Fig. 2, the utility model constitutes by adjusting screw 1, tightening nut 2, spring seat 3, spring 4, valve seat 5, pressing plate 6, diaphragm of rubber 7, sealing gasket 8, valve body 9, flap 10, filter 11 etc.Pressing plate 6 is threaded with flap group top, thereby barrier film 7 and flap are connected together; Adjust spring 4 and be located at barrier film 7 tops, can be in the height reliable adjustment of 0.05～0.6mPa.Valve body 9 made of copper and valve seat 5 are wear-resisting and be not afraid of corrosion; Sealing gasket 8 adopts little, the resistant to elevated temperatures fluorine rubber of residual deformation.Filter 11 is fixed on nearly ingress in the valve body 9 by nut 12, and the water that comes from entering the mouth just enters valve body after at first filtering through filter 11, has guaranteed the pure of water quality.
The outlet pressure of valve acts on barrier film 7 and flap 10 bottom surfaces, and when surpassing spring 4 setting values, spring 4 is compressed, and makes valve closing; Anhydrous when mobile when the downstream, outlet pressure will keep setting value, and when downstream week during water, outlet pressure descends, and spring 4 promotes barrier films 7 and moves downward, and opens the flap 10 of reduction valve.The current continuous flow moments later, the unlatching of reduction valve produces from inhibition effect, the pressure of outlet remains at the value of setting.
The utility model has following advantage compared to existing technology: simple and reasonable, can guarantee The water quality of valve body of flowing through is pure, easy for installation, and the outlet pressure precision is adjustable, be applicable to dwelling house and Industrial water supply system is the requisite equipment of protection feedwater branch system safe water.
