Bellows valve installation and maintenance matters needing attention when housing decoration water pipe valve installation points and matters needing attention

Bellows globe valves have the following advantages:
1, simple structure, convenient manufacturing and maintenance.
2, small working trip, short opening and closing time.
3, good sealing, sealing surface friction between small, long life.
Disadvantages of bellows globe valves are as follows:
1. The fluid resistance is large, and the required force is large when opening and closing.
2. It is not suitable for medium with particles, large viscosity and easy coking.
3, the adjustment performance is poor.
Bellows globe valve installation and maintenance should pay attention to the following matters:
1. The cut-off valve operated by hand wheel and handle can be installed at any position in the pipeline.
2. Handwheel, handle and lifting mechanism are not allowed to be used for lifting.
3, the flow of the medium should be consistent with the direction of the arrow shown in the valve body.
General water to go to the top, the cold, hot water outlet must be level, generally left hot right cool, pipeline laying needs to be horizontal and straight. The layout direction should be safe and reasonable. , the position of pipe card and the slope of pipe should meet the specification requirements. All kinds of valves should be installed in the correct position and straight, easy to use and maintenance. There should be an indoor main valve for inlet water. Before installation, check whether the water pipe and connecting accessories are damaged, trachoma or crack. If the structure is not reasonable when the water pipe is transformed, it will be very inconvenient to use in the future.
Conduit TRANSFORMATION HAS A lot OF PLACES THAT NEED to pay attention to, BECAUSE THE LAY OF GENERAL CONDUIT IS CONCEALED SEX, SO THE SECOND construction is more difficult, MUST pay attention to THE problem OF a lot OF RESPECTS.
Installation of valve
General water to go to the top, the cold, hot water outlet must be level, generally hot left and cool right, pipeline laying needs to be horizontal and straight. The layout direction should be safe and reasonable. , the position of pipe card and the slope of pipe should meet the specification requirements. All kinds of valves should be installed in the correct position and straight, easy to use and maintenance. There should be an indoor main valve for inlet water. Before installation, check whether the water pipe and connecting accessories are damaged, trachoma or crack.
The reserved position
In the kitchen, such as adding water softener, water purifier, small kitchen treasure should be considered in advance to leave the position of the water and power supply position. The cold and hot water pipes are entered into the wall. The depth of the trough should be checked when slotting. The cold and hot water pipes should not be in the same groove.
The right and left position of the shower mixing valve is correct, and installed in the middle of the bathtub (determine the size of the bathtub first), the height of the bathtub is 150-200mm, and the jacuzzi bathtub is reserved according to the model for the outlet. Mixed water valve hole distance is generally maintained in (dark installation)150mm, (open installation)100 mm, connecting rod shower according to the height of the room and the owner’s personal needs to determine the location of the outlet.
Reserve water intakes for household appliances
The water outlet of the toilet seat should be placed in a place where the view can be blocked by the toilet seat as far as possible. Join BODY SIT IMPLEMENT SHOULD DECIDE THE POSITION OF OUTLET ACCORDING TO MODEL, WANT TO STAY IN THE MIDDLE OF OUTLET BELOW CLOSESTOOL COMMONLY LEFT 200 MM PLACE.
Electric water heater generally needs to be fixed on the load-bearing wall, such as special circumstances, fixed on the non-load-bearing wall to do a fixed bracket, and the top layer to have enough position to do a fixed bracket, need to communicate with the water heater manufacturer in advance, in order to determine the location of the water heater outlet. When installing the inlet and outlet of the water heater, the inlet valve and the inlet valve must be considered and should be installed in the corresponding position.
There are many places to pay attention to the water pipe transformation, the above is only a part of it, but it is also a very important part. The design of the water pipe is very practical. If the structure of the water pipe is not reasonable, it will be very inconvenient to use in the future.
Especially the toilet and kitchen need to reserve the water outlet, must be designed in advance of the size, in the need to leave a good outlet. The quality of pipes is also very important. Poor quality pipes and pipes are easy to lead to leakage and seriously affect life.
