Abstract
The utility model discloses a conical sealing tap, belonging to a diaphragm type water tap with water as a medium. The utility model not only has all the advantages of the existing diaphragm type water tap but also a sealing part cone type rubber diaphragm sleeve can not be damaged. The utility model comprises a valve body, a valve cover, a cone type rubber diaphragm sleeve, a handle, a screw rod, a steel ball, a forcer, etc. A water outlet and a screw thread connecting with a water inlet pipe are arranged on the valve body, and the cone type rubber diaphragm sleeve is arranged on a circles type platform on the upper part of the valve body. The ring shape end of the cone type rubber diaphragm sleeve is impacted by the valve cover, and the cone portion of the forcer is closely attached with the conical end of the rubber diaphragm. When the handle is rotated right and left, the flow rate of water can be controlled.
Description
It is the diaphragm type water tap of medium that the utility model belongs to water.
Though that the diaphragm type water tap that Chinese patent CN85200678 introduces has is simple in structure, part is few, cost is low, zero water pollution, valve rod place do not have advantages such as leakage, but the structure of this water tap makes the obturator diaphragm of rubber be damaged easily, annular groove can appear when diaphragm of rubber is subjected to the extruding of valve body platform, when the rotation adjusting screw is closed water tap, diaphragm of rubber produces tensile buckling, can deepen annular groove, diaphragm of rubber is damaged, influence the sealing of water tap, produce and leak.
The purpose of this utility model provides a kind of improved diaphragm type water tap, and it not only possesses all advantages of existing diaphragm type water tap, and the obturator diaphragm of rubber can not be damaged.
The utility model is achieved like this: with an end is that taper shape, the other end are that ring, centre partly are that columnar circular cone type rubber spacer replaces traditional diaphragm of rubber; With an end is that taper shape, the other end are that columniform top replaces traditional pressure cap; One end of screw rod has circular hole; Between top and the screw rod steel ball is housed; The surface of contact of valve seat and rubber spacer is a conical surface.
The utility model not only possesses all advantages of existing diaphragm type water tap, and because the surface of contact of rubber spacer and valve seat is a conical surface, has increased the surface of contact at sealing position, so improved the sealability of water tap; Owing to when closing water tap, have only the cylinder of rubber spacer partly to be subjected to axial tension, so the rubber spacer can not be damaged; Owing between top and screw rod, a steel ball is housed, so when screw rod rotates, the top is only along the axis moving linearly, and can adjust position automatically with screw axis, make the two axial direction remain unanimity, guarantee the surface of contact no-float of valve seat and rubber spacer, realize best sealing effect.In the water tap using process, the rubber spacer can not be damaged, and can prolong the working life of rubber spacer, has prolonged the working life of water tap simultaneously yet, improves the use value of water tap.
Concrete structure of the present utility model is seen accompanying drawing.Accompanying drawing is a main sectional view of the present utility model.
Accompanying drawing of the present utility model is described a specific embodiment: valve body (1) has the screw thread (3) that is used for tapping into water pipe (2), can be directly and intake pipe (2) join, water in the intake pipe (2) enters the inner chamber (5) of valve body (1) by the valve seat (4) in the valve body (1), inner chamber (5) communicates with water outlet (6), and water flows out along water outlet (6).During installation, earlier screw rod (7) is screwed in valve gap (8), again handgrip (9) is sleeved on the square shaft (10) of screw rod (7) one ends, thick the end of square shaft (10) with the clinching method riveting, make handgrip (9) not take off and to make handgrip (9) relative movement not to be arranged from the square shaft (10) of screw rod (7) with screw rod (7).Then, steel ball (11) is put into the hole of screw rod (7), again the cylindrical end (13) of top (12) is inserted the hole that steel ball (11) are arranged in the screw rod (7).Rubber spacer (14) is put into valve body (1), again the valve gap (8) with screw rod (7), handgrip (9), steel ball (11) and top (12) is screwed in valve body (1), simultaneously the looped end of rubber spacer (14) (15) is compressed.Position among the figure, water tap is in opening state, as close water tap, rotary handle (9) moves downward screw rod (7), by steel ball (11) top (12) is moved downward simultaneously, the conical end (16) that top (12) promotes rubber spacer (14) moves down, shift to valve seat (4), the cylinder of rubber spacer (14) part (17) is stretched simultaneously, when the conical end (16) of rubber spacer (14) is fitted with the conical surface of valve seat (4), valve seat is closed, and water tap is closed, and water can not pass through.As opposite spin handgrip (9), then screw rod (7) moves upward, because the elastic force of rubber spacer (14) itself and the pressure of water, the conical end (16) of rubber spacer (14) is raised, throw off with valve seat (4), water can pass through, and flows out from water outlet (6).
Claims (3)
1, the circular cone type seal tap is made of valve body (1), valve gap (8), rubber spacer (14) and adjusting screw rod anti-loosing device, it is characterized in that rubber spacer (14) is a circular cone type rubber spacer, the adjusting screw rod anti-loosing device is equipped with handgrip (9), the other end screw rod (7) of steel ball (11) and an end are housed is the spiral pushing device formation that same central axis is formed in the conical top (12) that contacts with rubber spacer (14) for cylindrical, the other end that contact with steel ball by screwing in earlier valve gap (8) center screw, an end.
2, circular cone type seal tap according to claim 1 is characterized in that circular cone type rubber spacer (14) one ends are that ring, middle part are cylindrical shape for conical, the other end.
3, circular cone type seal tap according to claim 1 is characterized in that screw rod (7) is equipped with the Kong Weiyi circular hole of steel ball.
