Abstract
The utility model belongs to the field of the pipeline valve, and particularly relates to a straight-through type valve, comprising a valve body, a valve rod, a valve cover and a valve core. The middle of the valve rod is provided with a boss, and the lower part of the valve rod is provided with an eccentric wheel. The valve core is composed of a cylindrical core body whose surface is provided with a groove and a circular plate-shaped bulkhead. The core body is a hollow cylinder whose both ends are provided with a water inlet and a water outlet. The core body attaching to the bulkhead is sheathed with a sealing cushion. The back part of the bulkhead is connected with a spring. The utility model has the advantages of simple structure, simple manufacture and long service life, and is suitable for water supply pipelines.
Description
The utility model belongs to the pipeline valve field, particularly a kind of straight-through type valve.
The valve that generally uses in the water supply line is the spiral lift valve at present, and it finishes switching motion by the spiral motion extruding rubber ring of screw rod.Cause the cushion rubber rapid wear to leak more greatly owing to putting on the cushion rubber upward pressure, moreover because the valve internal thread directly contacts with water, and valve switch is frequent, make the oxide etch aggravation of screw thread place, life of valve shortens.For addressing the above problem, CN2175326Y discloses a kind of interior wheeled water nozzle of belling, it is that pipe coupling live part and housing do not have the splenium branch that water nozzle is divided into two-part, utilizes the pressure of tap water own to seal in pipe coupling, has eliminated the overweight destruction to cushion rubber of screw pressure.But its structure is comparatively complicated, and processing is difficulty comparatively.
The utility model purpose be to provide a kind of simple in structure, be convenient to process, the straight-through type valve of long service life.
Above-mentioned purpose is achieved in that a kind of straight-through type valve, comprises valve body, valve rod, valve gap and spool, in the middle of the valve rod boss is arranged, and stem lower portion has an eccentric wheel; Spool is formed by the cylindric core body and the connection of discoideus plug of surperficial trough of belt.
Core body is a hollow circular cylinder, and two ends are respectively equipped with water intake and water outlet.
The valve body lower inside is provided with circular groove.
Be close to plug on the core body and be with sealing gasket, be connected with a spring on the plug.
The utility model adopts no spiral shell rotational motion to drive the eccentric wheel rotation, realizes the switch of valve, has overcome the fragile shortcoming of existing spiral lift valve existence, has prolonged valve working life greatly; In the valve core structure design, the hollow cylindrical core body and the discoideus plug that the cylindric core body of surperficial trough of belt or two end part are provided with water intake and water outlet are coupled to one, and be simple in structure, is convenient to process; Connect a spring in the plug back, this spring back and pipe joint are pressed and are touched, thereby when hydraulic pressure is not enough, can realize smoothly that still valve closing state lower seal is water-tight.
Fig. 1 is the utility model structural representation;
Fig. 2 is core body A-A cutaway view Amplified image;
Fig. 3 is the valve rod plan view;
Fig. 4 is a valve core structure schematic representation among the embodiment 2.
Further specify the utility model below in conjunction with accompanying drawing by embodiment;
Embodiment 1, the straight-through type valve mainly is made of valve body 1, valve rod 2, valve gap 3 and spool in the present embodiment, valve gap 3 is spirally connected with valve body 1, be with leakproof circle 4 and leakproof circle pressure cap 5 on valve gap top, the valve rod, handle 6 is arranged at valve rod 2 tops, the centre has boss 7 to press with valve gap to touch, and the valve rod lower end is stretched in the valve body lower inside circular groove, makes valve rod 2 can not produce vertical or horizontal motion and influences the valve proper functioning.Eccentric wheel 8 is arranged at valve rod 2 bottoms, and spool is made of cylindric core body 10 connections that discoideus plug 9 and surface have groove, is close to plug 9 on the spool core body and is with a sealing gasket 11, is connected with a volute spring 12 on the plug 9, and volute spring 12 is pressed with pipe joint 13 and touched.
Claims (5)
1, a kind of straight-through type valve comprises valve body, valve rod, valve gap and spool, and feature of the present utility model is, in the middle of the valve rod boss is arranged, and stem lower portion has an eccentric wheel; Spool is formed by the cylindric core body and the connection of discoideus plug of surperficial trough of belt.
