Q:Is the overcurrent valve a check valve?: The flow valve is a check valve, the two principles of operation, performance, purpose is entirely different.The over-current valve is a protective valve in the pneumatic or hydraulic system that allows overpressure fluid to escape from the bypass.Check valve (check valve, also known as one-way valve or check valve), its role is to prevent the medium back in the pipeline.

Q:How to install industrial check valves? How should they be used?: 3, when installing check valve, should pay special attention to medium flow direction, should make medium normal flow direction and the direction of the arrow on the body is consistent, otherwise it will cut off the normal flow of media. Valve should be installed at the bottom of the pump suction pipe.

Q:Can the check valve be horizontally installed?: Lift check valve can be divided into straight through and vertical two. Straight through lift check valve can only be installed in horizontal pipe, vertical lift check valve is usually installed in vertical pipe.

Q:Does the check valve of the flue of the range hood work?: There is also a smoke exhaust smoke fire check valveThe utility model is installed at the rear end of a kitchen fume exhauster or a toilet exhaust fan to a common exhaust pipe inlet with a fireproof grade, and the fan is opened (exhaust gas) when working. In the fan does not work naturally closed (to prevent backflow, waste) or common duct inside temperature reaches a set value can be automatically closed, and within the stipulated period of time to meet the fire performance requirements, the role of smoke from fire retardant valve. This metal valve works on more, the basic effect should be good.

Q:How do I use the triangle and check valves?: The triangle valve is installed before the sanitary ware, the faucet and the appliance, so that it can be repaired after the damage of the faucet and the appliance.The check valve is equipped with a water meter and the water pump is prevented from flowing backwards in front of various water tanks and water pumps.

Q:I would like to ask you the following questions: Recently, the newly purchased three Lin electric water heater, installed in the upper layer of the five bathrooms, a faucet, that is left to wring out hot water, to the right to wring out cold water, mixed type.1 when there is no safety valve, the hot and cold flow is normal, but the check valve is dripping.2 manufacturers said that the high level to safety relief valve, dripping water and this also concerned, it took more than 100 safety valve, on the cold water pipe, but since then, hot water flow and its small, cold water normal, the check valve is still dripping.3 excuse me, check valve, check valve, safety valve is not a thing? Is it just a different name?4 is the relief valve the same as the relief valve?Now it's really a tough one. How do you solve the problem of small drop of water and hot water flow? The manufacturer said the pressure, but I very cold water washed!Thanks for the answer!: Check valve and check valve is to prevent backflow of water, the valve is used for pressure relief, when the water heater pressure is too high, the pressure through the pressure relief valve and pressure relief valve on the other: for water, the quality is not good, the main problems for the water pressure is too low to cause, and check valve and pressure relief valve will further reduce the pressure, you can try to check off a try, I think the check valve is useless. If not, just add a booster pump to the cold water inlet.

Q:What's the difference between a throttle valve and a check valve? Are they the same?: The same valve, but the effect is entirely different.The so-called "check back" is to let the fluid in the pipeline can only flow in one direction, can not let it return, so it is also called one-way valve. It works automatically.

Q:I also calculate each pump check valve and gate valve?: Are you talking about budget calculations? According to the bill of quantities valuation standard, the project code 030701019 has included what you said, without additional calculation.

Q:My house is public flue, a total of six floor I live five floors, with the side suction hood, hood in the windy outside started as soon as the check valve pops ring from occupancy, have what way?: The hood check valve is in two halves of plastic. It is too light and the wind vibrates. You can add some things, as long as the soot blowing function is OK (try several times). Able to solve problems.

Q:Pump adapter need check valve?: Pump adapter need check valve?
