Pressure safety valve-are the valve who are designed such that it can control the pressure , like in the water blowers etc,and Temperature safety valve are those who are used to regulate the temperature like, in water boilers.
yes
Raise the pressure in the boiler until the valve relieves and note the pressure at which it does so.
The lifting pressure is set by turning the adjusting nut on top of the valve.
A thermal relief valve is a liquid-only relief due to expansion of a liquid with increased temperature.A safety valve relieves pressure due to a gas.It should be noted that "safety valve" is a general term which could refer to Pressure Relief Valves (PRVs) or Pressure Safety Valves (PSVs), terms which are used synonymously in some industries (such as the petroleum industry) to refer to all relief devices in general.

safety valve
yes
the blowback or blowdown of the safety valve is at least 2 psi and for pressures over 100 psig is 2% of the popping pressure. The blowback is adjusted with the adjusting ring on the safety valve. The blowback is the pressure less than the popping pressure at which the safety valve will reset. Examples: a safety valve set to pop at 15 psig will reseat at 13 psig, the blowback is 2 psi. A safety valve set to pop at 250 psig will reseat at 245 psig the blowback is 5 psi or 2%.

the safety valve is mounted on the top of drum because, if the water level in boiler decreases a certain value, the temperature gets increased in water drum because of lack of water. So, increase in temperature result in high pressure in steam drum, as the safety valve is designed to withstand a certain pressure, after a cetain pressure, the safety valve is removed by high pressure of steam. this is why the safety valve is mounted on top of boiler drum. +++ Shall we sort out that lot? That answer is wrong. Its only link with water-level is that the valve has to be above the water anyway. If the boiler runs dry the safety-valve will not protect it. The safety-valve is there to prevent the steam pressure rising to a potentially a dangerous level. It is set to open at the boiler's designed working pressure.
The lifting pressure is set by turning the adjusting nut on top of the valve.
This is a safety valve for the pressure in the system do not exceed a certain limit. And the amount of pressure with respect to all system components are specified. This is for liquids and gases.
To release the excess pressure from its upstream.
Propane tanks are required to have a safety relief valve. The relief valve is a safety device on the propane tank to vent excess pressure.
The function of steam stop valve to supply steam to steam maniform and the function safety valve to prevent the steam high pressure over.
