Abstract
The utility model discloses a ball valve, which comprises a ball valve body, a valve rod, a sealing ring and a sphere center and is characterized in that the ball valve body is provided with a trapezoid groove at the valve rod; the sealing ring is a trapezoid body which consists of two sealing blocks and is internally provided with a spherical cavity; the sphere center is positioned in the spherical cavity of the sealing ring; the sealing ring and the trapezoid groove are closely combined; the sphere center is provided with an inverted T-shaped groove; the valve rod is a T-shaped valve rod; and the valve rod is arranged in the inverted T-shaped groove and combined with the sphere center. According to the utility model, because a sealing material and the sphere center need to be replaced after the valve internally leaks, convenience is provided for maintenance, and the problems that the valve buried in the wall body cannot be maintained and a cutoff valve is used on a high-rise building to cause reduction water pressure are solved.
Description
Technical field
The utility model relates to a kind of ball valve.
Background technique
People can use various ball valves in daily life and commercial production, the use of ball valve brings a lot of convenience for daily life and commercial production.But since people to modern life level require increasingly high; For attractive in appearance, so just water pipe and ball valve secretly are embedded in the body of wall during house decoration, the seal ring of existing ball valve is the mode that encloses sealing from valve body one side with the screw thread crush seal; In case valves leakage takes place just can't be keeped in repair; Must it be changed, will inevitably finishing be destroyed like this, make troubles for people's daily life.Also have modern architecture increasingly high,,, usually feel that hydraulic pressure is not enough thereby live in high-rise people because the stop valve high in and low out causes hydraulic pressure to descend owing to mostly be the stop valve that adopts.
Summary of the invention
It is a kind of easy to maintenance and can be used for the ball valve of tall building when valves leakage that the purpose of the utility model is to provide.
In order to solve above-mentioned technical problem; The utility model is realized through following technological scheme: a kind of ball valve, comprise ball valve body, valve rod, seal ring, the centre of sphere, and it is characterized in that: said ball valve body is opened a ladder-type trough at the valve rod place; The trapezoid body that one spherical hollow space is arranged in seal ring is made up of two sealing blocks; The centre of sphere is positioned at the spherical hollow space of seal ring, and seal ring and dovetail groove have an inverse-T-shaped groove for combining closely on the centre of sphere; Valve rod is " T " shape valve rod, and valve rod is put in the inverse-T-shaped groove of the centre of sphere and combined with the centre of sphere.
Screw thread in one is arranged at the secret top of stating dovetail groove, and an outer screw thread is arranged on the gland of valve rod, and the interior screw thread on outer screw thread and the dovetail groove cooperatively interacts.
The top of said valve rod is an octagon.
The utility model only needs to change sealing material and ball core owing to behind the valves leakage, thereby easy to maintenance, has solved valve and has been embedded in the problem that can't keep in repair in the body of wall, has also solved the problem that reduces hydraulic pressure at tall building use stop valve simultaneously.
Description of drawings
Fig. 1 is the structural drawing of the utility model;
Fig. 2 is the three-dimensional structure diagram of the utility model ball valve centre of sphere;
Fig. 3 is the three-dimensional structure diagram of the utility model seal ring.
Embodiment
Below in conjunction with accompanying drawing and practical implementation instance the utility model is done further to set forth.
Can know that from Fig. 1,2,3 the utility model is opened a ladder-type trough at valve rod 3 places of ball valve body 1, the trapezoid body of a spherical hollow space is arranged in seal ring 4 is made up of two sealing blocks, the centre of sphere 2 is positioned in the spherical hollow space of seal ring 4.Seal ring and dovetail groove be for combining closely, and the size of seal ring be for just getting into dovetail groove, through the extruding of gland, thereby plays the effect of sealing.On the centre of sphere 2, have an inverse-T-shaped groove, valve rod is " T " shape valve rod, and valve rod is put in the inverse-T-shaped groove of the centre of sphere, thereby combines, and can conveniently when maintenance, the centre of sphere and sealing material be taken out like this.Be processed with screw thread at the dovetail groove top.Gland at the valve rod top is an octagon, and an outer screw thread is arranged on the gland of valve rod, and the interior screw thread on outer screw thread and the dovetail groove cooperatively interacts, thereby makes valve rod and form 1 one integral body of ball valve body.
More than show and described basic principle of the utility model and the advantage of major character and the utility model; The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described, under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications; These variations and improvement all fall in the utility model scope that requires protection, and the utility model requires protection domain to be defined by appending claims and equivalent thereof.
Claims (3)
