Ball valve

Technical field

The utility model relates to the water heating pipe fittings field, especially relates to a kind of ball valve.

Background technique

At present, China has been maximum in the world structural material producing country and country of consumption.Main building material product cement, sheet glass, construction sanitary ceramic, stone material and materials for wall Isoquant rank first in the world for many years.Simultaneously, the building material product quality improves constantly, and the energy and raw materials consumption descend year by year, and various building materials continue to bring out, and building material product constantly upgrades.

There are many deficiencies in existing ball valve, and especially seepy question is serious, after repeatedly repeatedly keeping in repair, easily leaks, and need the seal ring that often more renew to reach and prevent the purpose of leaking, but effect and not obvious haves much room for improvement.

As from the foregoing, the problem that exists in present product is badly in need of solving.

The model utility content

The purpose of this utility model is to provide a kind of ball valve, can solve above-mentioned the deficiencies in the prior art part, and exquisiteness simple in structure improves sealing effect.

To achieve these goals, the technical solution of the utility model is as follows:

Ball valve, comprise valve body, and described valve body is provided with rotary switch, and the port that is arranged on the valve body both sides, it is characterized in that: be provided with screw thread on the outer wall of the end of port, the inwall of end is provided with the gear platform, forms concave surface on the table top of gear platform.

Further, described gear platform is 3-5mm apart from the end face of port.

Further, be provided with shared seal ring on the end face of port and concave surface.

The beneficial effects of the utility model: the utility model is provided with screw thread on the outer wall of the end of port, the inwall of end is provided with the gear platform, form concave surface on the table top of gear platform, be provided with shared seal ring on the end face of port and concave surface, such setting, enlarged sealing surface, when pipe fitting connects, contact just can be played good sealing effect, reduces the probability of leaking.

As from the foregoing, the utility model exquisiteness simple in structure, improve sealing effect.

In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
