Abstract
The utility model relates to a non-return water-sealed valve which comprises a box body, an inlet connection tube and an outlet connection tube arranged on the box body, a partition board and a floating ball bracket arranged in the box body, a floating ball and a water-sealed box. The utility model is characterized in that the hard floating ball is positioned among four guide plates fixed on the bracket, and a soft sealing ring is installed at the connection point of the inlet connection tube and the box body. The utility model has the advantages that the cost is reduced, the service life is prolonged, and the disaster of reverse irrigation contamination is relieved, due to the adoption of a sealing pair composed of the hard floating ball and the sealing ring. Because of the guide plates, the motion of the floating ball is oriented and the work is more stable and reliable.
Description
The utility model is a kind of overflow pipe in Drinking Water pond or industrial and mining enterprise process water pond and non-return water-sealed valve of connection, municipal drain of being used for.
The every pond of Drinking Water and overflow pipe in industrial and mining enterprise process water pond of supplying all is connected with the municipal drainage pipeline.In case therefore drainage system silts up, freezes or be untimely because of the big discharging of rainwater, will cause backing up of sewage or foul smell to scurry into and polluted water; Jeopardize health even life safety, perhaps influence a product.Known anti-against current valve exists complex structure, Placement is limited, and shortcomings such as the sealing pair weak point in working life formed of soft ball float and hard seal ring, ball float moving direction shakiness, and the manufacture cost height.
The purpose of this utility model provides a kind of novel non-return water-sealed valve, and it is simple in structure, working stability, long service life.
The purpose of this utility model is achieved in that it comprises having on the casing and import and export takes over, is provided with dividing plate and ball float support, ball float and water seal box in the casing, it is characterized in that the hard ball float is being fixed between four guide plates of support, soft seal ring is installed in entrance sleeve and casing junction.Fixing ball float support on the dividing plate in the casing forms the water seal box between dividing plate that extends below the support and casing in addition; Inlet/outlet is taken over and be can be connected or flange-type structure; Used guide plate is screwed on support.
The utility model has the advantages that:, reduced cost because the sealing pair that adopts hard ball float and hard seal ring to form replaces original valve seat construction, prolonged working life, exempted the disaster of pouring in down a chimney pollution, owing to used vertical guide plate, make the ball float motion orientation, more stable work is reliable.
Details of the present utility model provides by following examples and accompanying drawing thereof.
Fig. 1 is a structural representation of the present utility model.
With reference to the accompanying drawings, the utility model comprises entrance sleeve 1, and it is connected in casing 7 tops with bolt 5, clamps soft seal ring 6 between the two.The discharge connection 9 that is tightly connected is examined with spiral shell in side at casing 7, below casing 7, establish supporting leg 10, dividing plate 8 at the bottom of touching case straight down and is not arranged at casing 7 middle parts, it will be separated by between entrance sleeve 1 and the discharge connection 9, and side is fixed with four supports 3 within it, on support 3, fixed 2, four guide plates 2 of four vertical guide plates and surrounded the quadrilateral that does not seal, ball float 4 is positioned at wherein with screw 11.Below support 3, form water seal box B between dividing plate 8 and casing 7 bottoms.
During work, when overflow water was flowed through ball float and water seal box by entrance sleeve, ball float was located in and is state of rest on the support, retained the overflow water of certain depth simultaneously in the bottom, formed water seal, thereby stoped foul smell to be scurried into.Overflow water enters the municipal drainage system by discharge connection, when drainage system pours in down a chimney, pours in down a chimney water and is gone in the casing by the discharge connection reverse flow, this moment, ball float relied on the buoyancy of self, rise with pouring in down a chimney the water surface, combine and sealing channel with seal ring, stop and pour in down a chimney the water reverse flow by guide plate is spacing.Air cushion of compressed air formation this moment separates sewage and valve port, and protection valve port place seal ring is not contaminated, thereby plays the effect that water and odor pollution are avoided pouring in down a chimney in the protection pond.Water intake of the present utility model is taken over Placement can make flange-type or connected as required.
