Detailed Description

The first embodiment is as follows: please refer to fig. 1-5, which illustrates a high-sealing duplex gas ball valve, comprising a hollow connector 10, wherein the connector 10 is integrally formed by a screw thread section, a nut section and a hemisphere section, two guiding heads 11 are disposed on the outer circumference of the hemisphere section of the connector 10, a valve assembly is detachably disposed on one end of each guiding head 11 away from the connector 10, a sleeve joint 16 connected with a gas pipeline is disposed on one end of each valve assembly away from the connector 10, and a sealing assembly for sealing and clamping the gas pipeline is disposed on the outer circumference of each sleeve joint 16.

In this embodiment, the guiding head 11 is composed of a cylindrical section and a circular disc section, wherein the cylindrical section and the hemispherical section of the connecting head 10 are integrally formed and are communicated with the hollow part inside the connecting head 10, and an internal thread connected with the valve body assembly is provided at one end of the circular disc section of the guiding head 11 far away from the connecting head 10.

Further, the valve body assembly comprises a valve body 12 connected with the internal thread of the disc section of the guide head 11, a valve ball 13 is arranged in the valve body 12, a rotating shaft 14 penetrating through the valve body 12 and extending to the outside is arranged on the outer peripheral side of the valve ball 13, and a handle 15 is sleeved on the rotating shaft 14.

Further, the socket 16 is integrally formed at an end of the valve body 12 away from the connector 10.

The sealing assembly comprises two sealing plates 17, each sealing plate 17 consists of two plane parts and an arc surface part, clamping plates 18 are detachably arranged between the plane parts of the two corresponding sealing plates, a sealing gasket 19 is arranged on one side end face of each sealing plate 17, which faces a central line, and the sealing gasket 19 is arranged in a step shape, which faces one side end face of each sealing plate 17.

When the gas dry pipeline is installed, the gas pipe is embedded into a gap between the sealing gasket 19 and the sealing plates 17, so that the two sealing plates 17 cover the surface of the gas pipe, then the gas pipe is sleeved on the sleeve joint 16, and the two sealing plates 17 are locked by the clamping plate 18, so that the gas pipe is stably installed on the sleeve joint 16;
