Basic Introduction
Hydraulic shock (colloquial: water hammer; fluid hammer) is a pressure surge or wave caused when a fluid, usually a liquid but sometimes also a gas, in motion is forced to stop or change direction suddenly, a momentum change. This phenomenon commonly occurs when a valve closes suddenly at an end of a pipeline system, and a pressure wave propagates in the pipe.

This pressure wave can cause major problems, from noise and vibration to pipe collapse. It is possible to reduce the effects of the water hammer pulses with accumulators, expansion tanks, surge tanks, blowoff valves, and other features.

Mini potable expansion vessel, suitable for use as a water hammer shock arrestor. Stops pressure changes across water systems causing pipes to bang. The expansion vessel shock arrestor should be installed close to taps, valves and appliances in order to minimise the effect of shock on the system.

Dezhi offer a complete range of mini expansion vessels for use with potable water in domestic hot and cold water systems.The expansion vessels are manufactured to meet the requirements of PED 97/23/EC Directive 'Closed expansion vessels with built in bladder for installation in water'.
Design
Manufactured in Noryl plastic or stainless steel .Pre-pressurised air chamber with synthetic rubber compound bladder.The internal surface of the vessels in contact with the water are resistant to corrosion, thus maintaining water quality External surfaces are black or a natural finish for stainless steel.Suitable for temperatures up to 90˚C, resistant to ethylene or propylene glycol mixtures and has low gas permeability.

Dezhi mini expansion vessels are all tested according to the Pressure Systems Directive.

POTABLE WATER SHOCK ARRESTORS

Water hammer is caused during a pressure surge within a potable water system. The hammer is caused by a sudden stop or change of water flow within the system and is extremely common in domestic plumbing. Water hammer usually happens when the pressure within the system is too high - our water shock arrestor range will help to prevent water hammer. Our compact shock arrestor mini expansion vessel can be fitted at the point of use in order to prevent water hammer within the system.

How It Works
In a closed hot water circuit, the water cannot be compressed so any increase in volume, created by an increase in temperature, has to be accommodated by an expansion vessel.
When water is cold, the pre-charge pressure forces the bladder to collapse until the pump is started when the bladder starts to inflate.
As the temperature in the system increases, with the associated increase in pressure and volume, the expanded water enters the
bladder creating additional volume and lowering the pressure.When the temperature decreases, the pre-charge pressure forces the
water from the bladder and back into the main water circuit.
Service and Maintenance

Taizhou Tianyang  Electrical Co.,LTD recommend that the air pressure is checked annually and adjusted if necessary. This can be done using an air pressure gauge and foot pump.
