Description

Technical Field

[0001] The utility model relates to the technical field of heat-insulating ball valves, in particular to a heat-insulating ball valve capable of preventing a medium from solidifying. Background Art

[0002] The insulated ball valve is a specially designed valve, which is mainly used in situations where the medium temperature needs to be kept stable or the medium needs to be prevented from solidifying due to low temperature. This valve has been widely used in the petroleum, chemical, metallurgy, pharmaceutical and other industries.

[0003] Insulated ball valves are widely used in petroleum, chemical, metallurgy, pharmaceutical and other industries to insulate the transmitted medium. When using the existing insulated ball valves, two sets of jackets need to be installed on the outside of the insulated ball valve to insulate the insulated ball valve through the jackets to prevent the medium in the insulated ball valve from solidifying. However, when fixing the two sets of jackets, multiple sets of bolts need to be turned to lock the two sets, which is relatively cumbersome. Utility Model Content

[0004] The utility model aims to provide a heat-insulating ball valve capable of preventing medium from solidifying, so as to solve the problem that the heat-insulating jacket of the existing heat-insulating ball valve is complicated to install in the background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a heat-insulating ball valve capable of preventing medium from solidifying, comprising: a valve body and a fixing ring, the top of the valve body being movably connected to a rotating rod through a bearing, a valve core being inserted into the bottom of the rotating rod, and the outer side of the valve core being connected to a cavity inside the valve body,

[0006] The outer side of the valve body is sleeved with a first sleeve, and both sides of the first sleeve are fixedly connected with sealing strips, and the outer side of the sealing strip is slidably connected with a second sleeve, and both sides of the second sleeve are provided with sealing grooves matching the sealing strip, and the middle parts of one side of the first sleeve and the second sleeve are fixedly connected with sealing rings, and the top of the valve body is provided with an annular groove matching the sealing ring, and the outer side of the valve body is fixedly connected with a fixing ring, and the outer side of the fixing ring is sleeved with a sealing sleeve, and the inner sides of the first sleeve and the second sleeve are fixedly connected with the sealing sleeve, and one side of the first sleeve is fixedly connected with a fixing block, and the interior of the fixing block is movably connected with a two-way threaded rod through a bearing, and both ends of the two-way threaded rod are threadedly connected with a connecting plate, and a through hole is provided in the interior of the connecting plate, and the through hole is slidably connected with the sliding rod, one end of the sliding rod is fixedly connected to the first sleeve, and one end of the connecting plate is fixedly connected to a pressing block, and one side of the pressing block is provided with an inclined block, and one side of the inclined block is fixedly connected to the second sleeve, and a one-way valve is installed on one side of the second sleeve.

[0007] Preferably, a slide groove is provided on the top of the valve body, and the slide groove is slidably connected to the pressure rod, and a spring is sleeved on the outer side of the pressure rod.

[0008] Preferably, a clamping rod is fixedly connected to the bottom of the pressure rod, and a first clamping groove and a second clamping groove matching the clamping rod are formed on the top of the valve body.

[0009] Compared with the prior art, the heat-insulating ball valve that can prevent the medium from solidifying has the following beneficial effects: by docking the first jacket with the second jacket, and then rotating the bidirectional threaded rod to perform threaded transmission with the two sets of connecting plates, when the connecting plate moves, it will drive the pressure block on one side to squeeze the inclined block on one side of the second jacket, push the second jacket to be close to the first jacket, and complete the installation of the second jacket and the first jacket, and move upward by pulling the pressure rod. When the pressure rod moves, it will squeeze the spring through the rectangular block at the bottom to shrink it, and at the same time, the pressure rod will drive the clamping rod to move upward and disengage from the first clamping groove. At this time, the pressure rod can be rotated to drive the rotating rod to rotate, and the rotating rod will drive the valve core to rotate together to open it.

[0010] 1. The insulated ball valve is widely used in the petroleum, chemical, metallurgy, pharmaceutical and other industries. It can insulate the transmitted medium. When the first jacket and the second jacket are installed on the valve body, the first jacket and the second jacket are docked, and then the two-way threaded rod is rotated to thread the two sets of connecting plates. When the connecting plate moves, it will drive the pressure block on one side to squeeze the inclined block on one side of the second jacket, push the second jacket and the first jacket to fit tightly, and complete the installation of the second jacket and the first jacket. There will be a group of cavities between the two sets of jackets and the valve body. Pearl sand insulation material can be added to the cavity through a one-way valve to insulate the valve body and prevent the internal medium from solidifying. In this way, the above operation can facilitate the installation of the jacket on the outside of the insulated ball valve and insulate the insulated ball valve.

[0011] 2. The thermal insulation ball valve is widely used in the petroleum, chemical, metallurgy, pharmaceutical and other industries. It can insulate the transmitted medium. When the thermal insulation ball valve is opened, the pressure rod is pulled to move upward. When the pressure rod moves, the spring will be squeezed through the rectangular block at the bottom to shrink. At the same time, the pressure rod will drive the clamping rod to move upward and disengage from the first clamping groove. At this time, the pressure rod can be rotated to drive the rotating rod to rotate, and the rotating rod will drive the valve core to rotate together to open it. In this way, the above operation can facilitate the limiting of the rotating rod of the thermal insulation ball valve to prevent it from accidental opening and closing.

[0021] In specific implementation, the insulated ball valve is widely used in the petroleum, chemical, metallurgy, pharmaceutical and other industries, and can insulate the transmitted medium. When the first jacket 4 and the second jacket 6 are installed on the valve body 1, the sealing sleeve 10 on one side of the first jacket 4 is connected with the fixing ring 9 on the outside of the valve body 1, and the sealing sleeve 10 made of rubber material can be tightly connected with the fixing ring 9 to complete a primary seal. The second jacket 6 is installed in the same way.

At this time, the spring 19 will reset, and the pressure rod 18 will be pulled down, and the pressure rod 18 will drive the clamping rod 20 to enter the second clamping groove 22, completing the limiting of the pressure rod 18, preventing the rotating rod 2 from being accidentally closed after being hit.
