Background

The automobile air conditioner adopts the heat of the cooling circulating water of the automobile engine to provide a heat source for heating in the automobile, and the automobile air conditioner warm air water valve is used for controlling the cooling circulating water of the automobile air conditioner warm air system. The valve core of the warm air water valve is opened and closed in a rotary piston or rotary ball valve mode, so that the opening and closing speed and the sealing performance of the switch of the warm air water valve are influenced by a sealing piece which is in rotary friction with the valve core. In the prior art, a valve core sealing piece of an automobile warm air water valve is made of rubber or PTFE (polytetrafluoroethylene), and when the sealing piece of the valve core of the warm air water valve is a pure rubber sealing piece, the rubber has large frictional resistance, so that the sealing piece is easy to twist and clamp, the opening and closing speed of the warm air water valve is influenced, and the opening and closing are smooth. The surface of the PTFE material is hard, and the sealing surface is abraded due to the friction between the sealing element and the valve core by adopting the PTFE material, and a tiny gap generated after abrasion cannot be effectively compensated, so that the sealing performance and the durability are poor.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a sealing performance is good and the fast warm braw water valve of switching speed, this kind of sealing performance good and the fast warm braw water valve of switching speed solve prior art's warm braw water valve sealing performance good, the slow technical problem of switching speed inadequately.

The utility model discloses a sealing performance is good and fast warm braw water valve of switching speed, including warm braw water valve body, warm braw water valve body includes valve body and rotatory case, is provided with inlet tube and outlet pipe on the valve body, and rotatory case sets up in the valve body, and rotatory case is provided with radial through-hole, and through-hole and inlet tube and outlet pipe looks adaptation are provided with a disk seat between rotatory case and the outlet pipe, are provided with a shell fragment between disk seat and the outlet pipe, and the disk seat includes a sealing member, and the sealing member surface is provided with the one deck tectorial membrane, the tectorial membrane constitute by PTFE, PFA, ETFE, FEP or polyimide material.

Further, the sealing member 7 is made of a rubber material.

Compared with the prior art, the utility model, its effect is positive and obvious. The utility model discloses a warm braw water valve that sealing performance is good and switching speed is fast, simple structure, the installation is easy, has the sealing member that frictional resistance is low, and sealing performance is good, and frictional resistance is little, and switching speed is fast. A layer of coating is solidified on the surface of the rubber valve seat, the coating is made of PTFE, PFA, ETFE, FEP or polyimide materials, the rubber valve seat can be protected from abrasion, the lubricating function is achieved when the rubber valve seat is in contact with a valve core, and the friction resistance is reduced when the rubber valve seat is in contact with the valve core.
