Description
Technical field
The utility model relates to a kind of faucet valve core.
Background technique
Faucet valve core commonly used at present is by valve rod, valve core housing, ceramic plate up and down, compositions such as sealing gasket, valve rod, ceramic plate up and down, sealing gasket is placed in the valve core housing successively, there is a screw thread at the valve core housing middle part, be provided with the stop boss above the screw thread and between screw thread and stop boss, form a groove, be provided with ' O ' RunddichtringO in the groove, valve core housing is screwed on the swivel body, making up and down by rotation valve rod, the water port of ceramic plate communicates or closes the purpose that reaches the break-make water source, this technological scheme is simple in structure, good seal performance easy to use, but along with the growth ceramic plate of time and the mechanical wear of sealing gasket are easy to produce water leakage phenomenon, make troubles to use, and easy-maintaining not.
The model utility content
The utility model purpose is to provide a kind of faucet valve core, has simple in structure, easy to installation and maintenance, good seal performance characteristics.
The utility model provides following technological scheme for achieving the above object, a kind of faucet valve core, by valve rod, valve core housing, sealing gasket, ' O ' shape seal ring, ceramic plate is formed up and down, and it is characterized in that: valve core housing is a hollow, and its middle part is interval with the two sections screw thread, adjusting nut is rotatably connected in screw thread, but and free adjustment, forming a groove between two sections screw threads naturally, ' O ' shape seal ring is contained in the groove and can moves up and down.
Above-mentioned valve core housing top has a boss to match with the locating stud of valve rod can guarantee that valve rod rotates in several angle, the spool bottom has a square opening, square opening is the osculum of valve core housing, valve core housing bottom is provided with two breach and cooperates with convex tendon on the following ceramic plate edge, and it is static with respect to valve core housing to be used to limit down ceramic plate.
Above-mentioned valve rod top has a screw, and screw is built-in with locating stud, matches with the boss at valve core housing top, is used to limit valve rod and rotates in several angle; The valve rod middle part has two annular grooves, is equipped with ' O ' RunddichtringO in the groove, is used for the sealing between valve rod and the valve core housing; The bottom has a square opening, and square opening is a water outlet; Two convex tendons are established in the bottom, match with the groove at last ceramic plate edge, make the relative valve rod of ceramic plate static.
Have a semicircle orifice on the last ceramic plate, the edge has a pair of groove that matches with the convex tendon of valve rod; Also have a semicircle orifice on the following ceramic plate, the edge is provided with a pair of convex tendon that matches with the valve core housing bottom notch.
After adopting said structure, in the water leakage phenomenon that occurs taking place owing to mechanical wear, can be by regulating adjusting nut upwards, sealing gasket and seal ring spacing are increased, thereby valve core housing just can further screw in the water tap overcoat, put the top sealing gasket outward by water tap, make sealing gasket and further combine closely between the ceramic plate up and down, reach good sealing effect again; Use technical solutions of the utility model, also can reduce, make between sealing gasket and ' O ' RunddichtringO apart from being complementary, cause substandard products thereby overcome size deviation with the water tap overcoat by adjusting nut because the maching dimension deviation causes the substandard products number.The utility model is simple in structure, good seal performance, easy to installation and maintenance, long service life characteristics.
Description of drawings:
Fig. 1, the utility model three-dimensional exploded view;
Fig. 2, the utility model overall diagram;
Embodiment:
Shown in Fig. 1-2, the utility model is made up of valve rod 1, valve core housing 2, last ceramic plate 3, following ceramic plate 4, ' O ' RunddichtringO 5, sealing gasket 6 and adjusting nut 7, valve rod 1, go up ceramic plate 3, down ceramic plate 4, be contained in the valve core housing 2 successively, a sealing gasket 6 is placed in the port, and its internal component is combined closely.
Valve core housing 2 is a hollow, its middle part is provided with two sections screw threads separately, naturally form a groove 23 between last screw thread 21 and the following screw thread 22, groove is built-in with ' O ' RunddichtringO 5, and can move up and down, its top is provided with a boss 24, and its underpart has a square opening 25, and the bottom has pair of corresponding breach 26; Valve rod 1 first half exposes from valve core housing 2, and having a screw 11 near outside valve core housing 2 tops, be equipped with certain position pin 12 use that matches with the boss 24 at valve core housing 2 tops in the screw 11, can limit valve rod 1 rotates in several angle, the valve rod middle part is provided with two grooves 15, groove 15 built-in ' O ' seal ring 5, be used for the sealing between valve rod 1 and the valve core housing 2, valve rod 1 bottom is contained in the valve core housing 2 and hollow, have a square opening 13 above, the bottom is provided with two convex tendons 14 and matches with the groove 31 at last ceramic plate 3 edges, has a semicircle orifice 32 edges on the last ceramic plate 3 and is provided with a pair of symmetrical groove 31, also has a semicircle orifice 42 on the following ceramic plate 4, the edge is provided with a pair of symmetrical convex tendon, match with the breach 22 of valve core housing 2 bottoms, sealing gasket 6 is circular hollow, and intermediate throughholes 61 is the water inlet.
During use since the convex tendon 14 of valve rod 1 bottom be contained in the groove 31 on the ceramic plate 3, driving upward by rotary valve rod 1, ceramic plate 3 rotates, again because the convex tendon 41 on the following ceramic plate 4 is stuck in breach 26 interior can not the rotations of valve core housing 2 bottoms, so just make ceramic plate 3 with respect to ceramic plate 4 rotations down, rotation by valve rod 1 can reach communicating and closing of semicircle orifice on the ceramic plate up and down, reaches the purpose of opening and closing the water source; When water leakage phenomenon occurring owing to mechanical wear, can regulate on the adjusting nut 7 and move, the step screws in the water tap overcoat to make valve core housing 2 advance down again, thereby make its extruding internal component by last top sealing gasket 6, it is reached again combine closely, reach good sealing property, also prolonged service time simultaneously.
