Cabin flush gate valve related introduction

Bulkhead flush gate valves are used for product oil and chemical tankers, mounted on the bottom of the hold, with the left flange attached to the bulkhead by studs and the right end tube leading to the hold. The original use of the barrier gate valve body sealing port is circular, gate seal pair is circular. This structure results in the residual medium in the cabin when unloading the fluid medium in the cabin. The characteristics of the bayonet flush gate valve are the planar design at the bottom of the valve. The bottom of the valve is only 5mm away from the bottom of the cabin after unloading or cleaning the cabin so as to meet the requirements for fluid medium transmission in the cabin. Bulkhead flat gate valve is mainly composed of the main valve body, the left valve body, the right valve body, gate, shaped seal ring, stem, valve cover and other components. The valve body is composed of the main valve body and the machined left valve body and the right valve body. Due to the long-term immersion of the valve in corrosive medium, all the parts are made of the solution-treated austenitic stainless steel (CF8M, 316), except that the profiled seal ring is made of PTFE. The opening and closing of the shutter is carried out by the upper end of the valve rod extending through the valve cover and connected with the transmission mechanism. The electric or manual driving rotation drives the shutter to move up and down, and the shutter is subjected to downward and lateral forces to make the two sealing surfaces well The seal is closed, and vice versa. In order to achieve the valve does not open after leaving the cabin and the media is sealed and reliable, the bottom of the main valve is designed to be a flat seal, the left valve body seal, the right valve body beveled seal to ensure that with the size and sealing requirements. The gate is composed of a gate body and a special-shaped sealing ring. The special-shaped sealing ring is fixed by a screw and a locking pad in a special-shaped sealing groove on the gate body. Shaped seal ring and the valve body between the end seal and the bottom of the seal seal. When the valve is closed, the slant of the ram body is stressed, at the same time, the bottom plane and the arcuate surface of the ram body are forced to achieve the reliable sealing effect of the valve. Bulkhead gate valve is designed and manufactured according to market demand. The valve has the overall structure is compact, easy to operate, reliable sealing and long life and other characteristics, the installation by the user, good performance, similar to the use of conditions have better market prospects.

Dispenser Mass Flow Meter

Sealand is a trustworthy manufacturer of CNG Dispenser Mass Flow Meter, LNG Dispenser Mass Flow Meter, LPG Dispenser Mass Flow Meter, ATEX, CE & IECEx approved.

With its high accuracy, wide rangeability and reliable performance, Sealand meter has been applied in many kinds of industries during the last 8 years. Unlike others who only focus on the measurement of liquid at normal pressure & temperature, Sealand has conquered the difficulty in the measurement under severe conditions, such as high pressure, high viscosity, high & low temperature.

Take CNG (compressed natural gas) for example. As the saying goes, the meter can measure anything else if it can measure CNG. It is quite hard to measure gas under high pressure. The sensor must be able to bear high pressure; in this way, the thickness of flow tube must be increased, so the transmitter shall be more sensitive to detect the signal; however, Sealand made it. Sealand's first model is specially designed for CNG dispenser, and now thousands of this model are put into use on the market.

Here are the pictures of Sealand Mass Flow Meter in Dispenser for your reference.
