Abstract
The utility model discloses a watertight valve which comprises a valve seat, a valve stem is arranged on the valve seat, the lower end of the valve stem is provided with a sphere, a sealing device is arranged at the position of the valve stem of the valve seat, the upward side of the sealing device is connected with a valve deck, the valve deck is in threaded rotary connection with the valve seat, each of the upper and lower ends of the sealing device is provided with a ring structure which is raised from the periphery to the middle, the lower part of the sealing device is provided with a ring gasket, the upper end of the ring gasket is fixed to an elastic device, the upside of the elastic device is connected with the ring structure, the elastic device is a spring, the sphere is elliptic, and the ring gasket is made of silicone rubber. The watertight valve disclosed by the utility model is simple in structure and convenient to install; and because the sealing device is adopted, a situation that the valve stem is in contact with fluid such as water and oil gas for a long time is avoided, the influence caused by the erosion and the like of fluid is avoided, and the abrasion is reduced, leakage and aging are avoided futher, and the service life of the valve is improved.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of valve of water-impervious.
Background technique
Existing valve is after being used a period of time, and stem position all can be because certain Seepage appears in abrasion condition, and water valve is long-time no the time, get rusty easily and block, impact is used, and if valve is often used, the situation of there will be tooth, easily aged deterioration.
The model utility content
Technical problem to be solved in the utility model is for the deficiencies in the prior art, and a kind of valve of water-impervious is provided.
To achieve these goals, the measure taked of the utility model:
A kind of valve of water-impervious, comprise valve seat, described valve seat is provided with valve rod, the lower end of valve rod is provided with spheroid, stem position in valve seat is provided with seal arrangement, the seal arrangement top is connected with valve gap, valve gap is connected with the valve seat screw thread rotation, the two ends up and down of described seal arrangement are provided with the ring structure of surrounding to intermediate projections, the bottom of seal arrangement is provided with ring washer, ring washer upper end and elastic device are fixed, the upside of elastic device is connected with ring structure, elastic device is spring, spheroid is oval, ring washer is the silicone rubber material, valve seat interior surface is coated with anticorrosive PTFE erosion layer, valve gap is provided with annular handle.
Described valve rod passes ring structure, ring washer is connected with spheroid, and the upper end of valve rod is connected with handle, and handle is fixedly connected with by nut with valve rod, and valve seat is provided with the projection of restriction handle the sphere of activities.
The beneficial effects of the utility model: the utility model is simple in structure, easy for installation, owing to adopting seal arrangement, avoided the Long contact time of the fluids such as valve rod and water, oil gas, and avoided erosion that is subjected to fluid etc. to affect, reduce wearing and tearing, thereby avoided seepage, aging, improved the working life of valve.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, a kind of valve of water-impervious, comprise valve seat 1, described valve seat 1 is provided with valve rod 2, the lower end of valve rod 2 is provided with spheroid 3, valve rod 2 positions in valve seat 1 are provided with seal arrangement 4, seal arrangement 4 tops are connected with valve gap 5, valve gap 5 is connected with valve seat 1 screw thread rotation, the two ends up and down of described seal arrangement 4 are provided with the ring structure 6 of surrounding to intermediate projections, the bottom of seal arrangement 4 is provided with ring washer 7, ring washer 7 upper ends and elastic device 8 are fixing, the upside of elastic device 8 is connected with ring structure 6, can make valve rod 2 not be subjected to the erosion of fluid, good airproof performance, also avoided the appearance of seepage situation, service time is longer,
Described valve rod 2 passes ring structure 6, ring washer 7 is connected with spheroid 3, the upper end of valve rod 2 is connected with handle 9, handle 9 is fixedly connected with by nut 10 with valve rod 2, valve seat 1 is provided with the projection 11 of restriction handle 9 the sphere of activities, can prevent the excessive impact on valve rod 2 and valve body of handle 9 the sphere of activities, reduce because of the impact of handle 9 undue forces on valve body.
Those ordinary skill in the art's simple change and replacement are all within protection domain of the present utility model.
