Description

A three-way ball valve

Technical Field

The utility model relates to the field of ball valves, in particular to a ball valve with a three-way structure.

Background Art

There are two types of three-way ball valves: T-type and L-type. The T-type can connect three orthogonal pipelines and cut off the third channel, playing the role of diversion and confluence; the L-type three-way ball valve can only connect two orthogonal pipelines, and cannot keep the third pipeline connected at the same time, and only plays a distribution role. The working principle of the three-way ball valve is to make the valve unblocked or blocked by rotating the valve ring. The ball valve is light and small in size, can be made into a large caliber, has reliable sealing, simple structure, and is easy to maintain. The sealing surface and the spherical surface are often in a closed state and are not easily eroded by the medium. It is widely used in various industries.

The interfaces of three-way ball valves commonly used in industry are generally connected by flanges. As we all know, the fluid flowing in the three-way ball valve cannot be observed intuitively. When technicians need to know the depth of the fluid flowing in the valve body, they need to observe from the pipe mouth, so there is room for improvement.

Utility Model Content

The utility model aims to provide a ball valve with a three-way structure to solve the problems raised in the above-mentioned background technology, and has the advantage of conveniently observing the depth of the fluid in the valve body.

To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a three-way ball valve, comprising a valve body and a valve tube, a connecting rod is arranged in the valve tube, one end of the connecting rod is integrally connected to a fixing plate, the top of the connecting rod is integrally connected to a placing plate, the side of the valve tube is integrally connected to a fixing plate, the side of the connecting rod is integrally connected to a sliding plate, a plurality of surrounding plates are integrally connected to the circumference of the placing plate, a weight is placed on the placing plate, and a fixing part for limiting the movement of the sliding plate is arranged on the side of the fixing plate.

By adopting the above technical solution, the fixed plate adopts a low-density foam block so that the fixed plate will be suspended above the fluid. When it is necessary to judge the approximate depth of the fluid, a heavy object is placed on the placement plate, and the fixed plate at the lower end is moved down until it contacts the bottom of the valve tube. The approximate depth of the fluid is judged by the distance the fixed plate moves down. The size of the water flow can easily cause the connecting rod to swing up and down. When the connecting rod does not need to swing up and down, the fixing part is used to limit the movement of the sliding plate, thereby limiting the movement of the connecting rod.

As a further solution of the utility model: a groove is arranged on the enclosure.

By adopting the above technical solution, technicians can put heavy objects into the placement plate from the groove.

As a further solution of the utility model: a cover plate is clamped on the top of the placement plate, and a round block is integrally connected to the top of the cover plate.

By adopting the above technical solution, during inspection, the cover plate is placed above the placement plate, and the arrangement of the round block makes it easy to take the placement plate.

As a further solution of the utility model: a movable plate is slidably connected in the groove, and a limiting rope is connected between the movable plate and the outer side wall of the enclosure.

By adopting the above technical solution, when the number of weights needs to be increased, the movable plate is moved out of the groove, the weights are placed on the movable plate, and then the movable plate is pushed until the movable plate is in the groove. The setting of the limiting rope ensures that the movable plate and the enclosure are always in a connected state.

As a further solution of the utility model: the fixing member includes a threaded rod threadably connected to the fixing plate.

By adopting the above technical solution, when there is no need to move the sliding plate, the threaded rod is rotated until the threaded rod squeezes the lower side of the sliding plate, thereby achieving the purpose of fixing the sliding plate.

Compared with the prior art, the beneficial effects of the utility model are:

The fixed plate is made of a low-density foam block so that the fixed plate will float above the fluid. When it is necessary to judge the approximate depth of the fluid, a heavy object is placed on the placement plate to allow the fixed plate at the lower end to move down until it contacts the bottom of the valve tube. The approximate depth of the fluid is judged by the distance the fixed plate moves down. The size of the water flow can easily cause the connecting rod to swing up and down. When the connecting rod does not need to swing up and down, the fixing part is used to limit the movement of the sliding plate and thus limit the movement of the connecting rod.
