Description

Anti-theft heater is with pressing from both sides mould

Technical Field

The utility model relates to a heat exchanger equipment technical field, more specifically say, the utility model relates to a thief-proof heater is with pressing from both sides mould.

Background

The butt-clamping mould is a commonly used communicating body for pipeline butt joint, and is divided into a butt-clamping butterfly valve, a butt-clamping lifting check valve and the like.

The butterfly plate of the wafer butterfly valve is arranged in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, the rotation angle is 0-90 degrees, the flow regulation effect can be achieved, when the butterfly plate rotates to 90 degrees, the valve reaches 100% opening, and the wafer butterfly valve is simple in structure, small in size, light in weight and only composed of a few parts. And the valve can be quickly opened and closed only by rotating 90 degrees, the operation is simple, and meanwhile, the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the resistance generated when the medium flows through the valve body, so that the pressure drop generated by the valve is small, and the butterfly valve has a good flow control characteristic. The butterfly valve has two sealing types of elastic soft sealing and metal sealing. The sealing ring of the elastic soft sealing valve can be embedded on the valve body or attached to the periphery of the butterfly plate.

The opposite-clamping lift check valve is a valve which automatically opens and closes a valve clack by medium flowing, and is used for preventing medium from flowing backwards, and is also called a check valve, a one-way valve, a reverse flow valve and a back pressure valve. The check valve is an automatic valve and mainly used for preventing medium from flowing backwards, preventing the pump and a driving motor from reversing and discharging container medium. Check valves may also be used to provide make-up lines to auxiliary systems where the pressure may rise above the system pressure. Check valves can be largely classified into swing check valves (rotating about the center of gravity) and lift check valves (moving along an axis), which are generally installed horizontally in a pipe.

However, in actual use, most of the existing butt-clamp molds are welded to plastic pipes inserted in the existing butt-clamp molds, and are easily corroded by fluid, so that the joints are damaged, a water leakage phenomenon is formed, the pipes can be separated from the butt-clamp molds seriously, and the normal use of the butt-clamp molds is further influenced.
