Description

Technical Field

[0001] The utility model belongs to the technical field of pressure transmitters, in particular to a steam pressure transmitter for a ship steam turbine. Background Art

[0002] A pressure transmitter is a sensor used to measure fluid pressure and convert it into a standard electrical signal (such as 4-20mA) for output. It plays an important role in industrial control systems, especially in situations where pressure changes need to be accurately monitored, such as chemical, petroleum, construction, water treatment, and smart manufacturing.

[0003] The working principle of a pressure transmitter usually involves measuring the pressure exerted by the fluid on the sensitive element of the sensor and converting this physical quantity into a usable electrical signal output. The working environment and use conditions of a marine steam turbine are different from those of a power station steam turbine. It is installed on a deformable hull base and is often affected by the swaying and impact of the hull, which can easily cause damage to the pressure transmitter. Traditional pressure transmitters are difficult to meet the usage requirements. For this reason, we propose a steam pressure transmitter for a marine steam turbine. Utility Model Content

[0004] The utility model aims to provide a steam pressure transmitter for a ship steam turbine, which solves the problem that the existing steam pressure transmitter for a ship steam turbine is often damaged by the swaying and impact of the ship body during use.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a steam pressure transmitter for a steam turbine of a ship, comprising a pressure transmitter, a protective assembly is fixedly installed at the bottom of the pressure transmitter, a conversion joint is fixedly welded at the bottom of the protective assembly, a butt joint is detachably connected to the bottom of the conversion joint through a connecting bolt, a shock absorbing element is also arranged at the position where the butt joint is connected to the conversion joint, a detection probe of the pressure transmitter penetrates the protective assembly and extends to the inside of the butt joint, and further comprises:

[0007] A fixing component is detachably connected to the side wall of the protection component for fixing the protection component.

[0008] Furthermore, the protection component includes a protection base with a cavity inside, a heat dissipation element is arranged on the inner side wall of the protection base, and a coolant injection port and a coolant discharge port are respectively arranged on both sides of the protection base.

[0009] Furthermore, the heat dissipation element is a spiral plate-shaped structure, the heat dissipation element is made of a heat-conducting material, and the heat dissipation element forms a spiral fluid channel around the inner wall of the protective base and the detection probe.

[0010] Furthermore, the coolant injection port and the coolant discharge port are respectively connected with a delivery hose, and the delivery hose is used to connect to a coolant supply device.

[0011] Furthermore, the shock absorbing element is a shock absorbing rubber pad, and through holes for connecting bolts to pass through are opened at the four corners of the shock absorbing element. One end of the connecting bolt that passes through the through hole is threadedly connected and fixed to the docking joint.

[0012] Furthermore, the fixing assembly includes a threaded rod threadedly connected to the side wall of the joint, the outer wall of the threaded rod is sleeved with a hollow tube, one end of the hollow tube is fixedly connected with a fixing plate, the side wall of the fixing plate is provided with a positioning hole, the side wall of the hollow tube is threadedly connected with a fixing bolt, and the fixing bolt penetrates into one end of the hollow tube and presses against the outer wall of the threaded rod.

[0013] The utility model has the following beneficial effects:

[0014] Through the arrangement of the pressure transmitter, protective assembly, adapter, joint, shock absorbing element and fixing assembly, the hollow tube and threaded rod cooperate with each other to adjust the length of the entire fixing assembly, thereby facilitating the installation of the pressure transmitter on a fixed object for auxiliary support. When vibration occurs, the shock absorbing element can also be used to absorb it, thereby reducing the impact of the turbine's own vibration on the pressure transmitter. Coolant can also be injected through the coolant injection port. The coolant contacts the heat dissipation element to cool down the entire pressure transmitter, thereby avoiding the impact of temperature overload on the pressure transmitter caused by long-term use.
