Construction points for installation of sanitary ware
1 All the hydraulic pressure test and water shut-off test connected to the sanitary ware have been completed, and the installation of sanitary ware is carried out after pre- and hidden pre-inspection procedures have been completed. Sanitary appliances should be inspected and cleaned before being installed. Accessories and sanitary ware should be matched, and some sanitary ware should be prefabricated before installation. 2 The connection between the drain outlet of the sanitary appliance and the socket of the drain pipe must be tight. 3 Installation should meet the following requirements: the position is correct, the installation is stable, the appearance is correct, the tightness, the detachable performance is good, and the anti-blocking after installation.
Wash basin installation for bathroom fixture installation
1 wash basin products should be flat and non-destructive. The drain plug should have an overflow hole of not less than 8 mm in diameter.
2 When the drain plug is connected with the washing basin, the overflow plug of the drain plug should be aligned with the overflow hole of the sink as much as possible to ensure the smooth flow of the overflow. After the insert, the upper end of the drain plug should be lower than the bottom of the wash basin.
3 bracket fixing bolts can be galvanized bolts or galvanized metal expansion bolts of not less than 6mm (if the wall is porous brick, expansion bolts are strictly prohibited).
4 After the washing basin is connected with the drain pipe, it should be firm and compact, and easy to disassemble. The joint should not be open. Silicone paste caulking is applied to the wash basin and wall contact.
5 If the wash basin drain trap and faucet are plating products, the plating should not be damaged during installation.
Toilet installation for sanitary fixture installation
1 Before installing the toilet, the crosshair should be drawn according to the design of the house. When there is no design in the design, the minimum distance from the center of the water outlet of the squat toilet is 660mm for ceramic water seal and 620mm for cast iron water seal.
2 The joint between the upper and lower mouth of the toilet water seal and the toilet or pipe should be filled with two laps of oil and linen, and the outer part is sealed with oil putty or paper ash.
3 After installation, it should be protected.
Urinal installation for bathroom fixture installation
1 Before installation, check whether the reserved pipe outlet is in a vertical line, and the spacing is consistent. After meeting the requirements, find the center line according to the nozzle, clean the surrounding pipe, remove the temporary pipe plug, and wipe the putty. Under the urinal, place a mixture of cement and white ash (proportion 1:5). The vertical urinal is steadily leveled and aligned; the vertical urinal is smeared and smeared with white cement slurry on the wall and the ground.
2 The urinal upper water pipe requires concealed installation, and the angle steel is connected with the urinal.
The center of the 3 angle valve outlet should be aligned with the urinal inlet and outlet center.
4 Before the piping, the urinal installation center line should be drawn on the wall, the position should be determined according to the design height, the cross line should be drawn, the urinal center line should be drilled, and the wooden needle or plastic expansion bolt should be used.
5 Use a wooden screw and a nylon hot ring to gently slap the urinal against the wooden brick, without being skewed or inclined. 6 When the urinal drain interface is a socket, it is sealed with oil putty.
Washbasin installation for bathroom fixtures
1 First install the washbasin water: first remove the root of the drain, eye ring, rubber pad, put the putty on the pad and insert it into the drain hole of the basin. The overflow in the drain should be directed to the overflow in the drain of the washbasin. The mouth and eyes, with a padded putty washer on the outside, put on the eye ring and bring the mother with the mother. Then use a self-made wrench to catch the cross ribs of the drain, and use a flat-nose wrench to the mother to the tightness.
2 Then install the basin faucet: first remove the faucet root mother and lock nut, put the putty at the root of the faucet, insert the basin water supply hole, and then insert the rubber eyelet underneath, take the root mother and hold the water with the left hand. Mouth, right hand with a homemade eight-character dead wrench to tighten the lock to a moderate degree of tightness.
3 Then install the washbasin: first install the bracket. Draw a vertical line on the wall according to the center of the drain nozzle, measure the height from the ground upwards, draw a horizontal line, draw the position of the bracket horizontally according to the width of the basin, and then use the wood with a steel washer for the washbasin bracket. The screws are fixed on the pre-embedded wooden bricks to be fixed on the wall surface, and then the washbasin is placed on the bracket to level and find the hooks in the fixing holes under the basin, and the fixing bolts of the basin frame are tightened to find the level.
4 Then install the drain pipe of the washbasin: apply lead oil on the lower end of the drain wire of the washbasin, wrap a little hemp, and screw the trap on the drain (p-type directly screw the trap to the drain) The tightness is moderate, and then the lower end of the water trap is wrapped around the drain and inserted into the drain pipe. The rubber pad is placed at the joint of the trap, and the lock is tightened by hand and straightened, and then the wrench is used. Tighten tightly to the tightness, and use the putty to close and smooth the drain pipe. The oil-filled asbestos rubber sheet is sealed at the joint between the washbasin and the drain plug.
5 Finally install the water supply pipe of the washbasin: firstly measure the size of the short tube, install the angle valve, then apply oil and wrap the thread at the other end of the short tube, and screw it on the reserved water supply port (if it is concealed) The pipe with the retaining plate should be placed on the short section first. After the pipe is finished, fill the protective plate with putty, level the wall, press the actual, clean the spilled putty) and straighten it tightly. Cut the copper pipe (or plastic pipe) according to the size, remove the lock valve of the angle valve and the faucet, and put the back cover on the copper pipe (or plastic pipe), wrap the oil pan root rope or lead oil twine respectively, the upper end Insert the root of the faucet, insert the lower end into the middle of the angle valve, screw the upper and lower locks to the appropriate degree, straighten, straighten, and clean the exposed hemp.
CNC Internal Cylindrical Grinding is mainly used for grinding the inner hole and end face of pot teeth and large bearing ring parts to ensure the accuracy of the inner hole and end face. Is a new generation of high-precision, high-efficiency production machine tools. The entire grinding cycle of the machine tool is automatically completed, and the operator only needs to assemble and disassemble the workpiece. CNC internal grinder is used to grind cylindrical and conical small holes, and can also grind outer circle and end face. The working spindle, Internal Grinding head and external grinding head are all lubricated with oil mist. The CNC internal grinder system has strong programming functions, simple operation and easy to learn, and has a variety of special functions that meet the requirements of grinding processing, which can meet the processing needs of users for a variety of parts.
