Description

Technical Field

[0001] This utility model relates to the field of three-way ball valves, specifically a heat-insulating three-way ball valve. Background Technology

[0002] Three-way ball valves, as a type of pipeline valve, are mainly suitable for applications such as switching, reversing, and dividing / combining gas or liquid media. In the food industry, especially in chocolate production, the three-way ball valves currently widely used include a T-shaped valve body, a connecting cavity on the T-shaped valve body, a valve core installed in the connecting cavity, and three connecting pipes that communicate with the connecting cavity of the T-shaped valve body. During the flow of the media, long-term heat preservation is required, but current ball valves do not have this function and need to be improved. Utility Model Content

[0003] The purpose of this utility model is to provide a heat-insulating three-way ball valve to solve the problems mentioned in the background art, which has the advantage of heat preservation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a heat-insulating three-way ball valve, comprising a valve body, a connecting rod ball disposed within the valve body, a rotating block integrally connected to the lower end of the connecting rod ball, a rotating groove for accommodating the rotating block, a heat-insulating cavity surrounding the connecting rod ball circumferentially disposed inside the valve body, the heat-insulating cavity for accommodating a flowing medium, a communicating groove communicating with the heat-insulating cavity, and an extension block integrally connected to the valve body at the opening of the communicating groove.

[0005] By adopting the above technical solution, the valve body with insulation cavity in this solution eliminates the risk of internal and external leakage. The internal design features a ball that is integrally connected to the valve stem, and the ball fits completely with the entire valve seat without any gaps. This ensures that no medium is blocked in the cavity during valve use, making the valve easier to use and saving maintenance costs. The rotating block is located in the rotating groove, which increases the stability of the connecting rod ball during rotation. The flowing medium flows in the insulation cavity, forming a relatively constant temperature state. The connecting groove and extension block provide inlet and outlet for the medium to flow in and out, forming a flow state.

[0006] As a further embodiment of this utility model: valve seats are provided on both sides of the connecting rod ball inside the valve body, a fixing ring is provided on the side of the valve seat, and a disc spring is provided between the valve seat and the fixing ring.

[0007] By adopting the above technical solution, the disc spring allows the valve seat to move towards the ball, increasing the connection strength between the two.

[0008] As a further improvement of this utility model: the fixing ring is threadedly connected to an adjusting bolt, and one end of the adjusting bolt abuts against the disc spring.

[0009] By adopting the above technical solution, the tension of the disc spring can be adjusted by setting the adjusting bolt, thereby adjusting the tension between the valve seat and the connecting rod ball.

[0010] Preferably, the valve body is provided with a packing body located circumferentially to the connecting rod ball, and a packing gland is provided above the packing gland, the packing gland being threadedly connected to the valve body.

[0011] As a further improvement of this utility model: a drive bracket is bolted to the top of the valve body, and a through groove for accommodating a packing gland is provided in the middle of the drive bracket.

[0012] By adopting the above technical solution, the drive bracket plays a supporting role, and the through groove is set to accommodate the packing gland.

[0013] Preferably, the valve seat has multiple sealing grooves on its side, and a sealing ring is provided in each sealing groove.

[0014] As a further improvement of this utility model, a drain plate is threadedly connected to the lower side of the valve body.

[0015] By adopting the above technical solution, the drain plate can be removed when the insulation cavity needs to be cleaned, making cleaning easier.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This solution is used for switching media in food production equipment, especially chocolate production equipment. Due to the requirements of the production process, it is designed as an integral heat-insulating cavity to eliminate the risk of internal and external leakage. The internal design is an integral ball connected to the ball rod. The ball fits completely with the entire valve seat without leaving any gaps, so that no medium is blocked in the cavity during the valve's use. The valve is easier to use and saves maintenance costs during use.

[0018] 2. The valve body in this design features an insulated cavity, eliminating the risk of internal or external leakage. The internal design incorporates a ball joint that is integrally connected to the valve seat, ensuring a seamless fit without any gaps. This prevents media from clogging the cavity during operation, making the valve easier to use and reducing maintenance costs. The rotating block, positioned within a groove, enhances the stability of the connecting rod ball during rotation. The flowing medium remains relatively constant within the insulated cavity. The connecting groove and extension block provide inlet and outlet ports for media flow, ensuring smooth flow. Attached Figure Description
