Abstract
The utility model discloses a water supply valve with a ceramic closing element with an improved structure. The structure comprises a valve body, a switch handle, ceramic plates and a seal element. The valve body is provided with a water inlet and outlet, a water flow channel, etc. The ceramic plates are arranged at the middle of the water flow channel, wherein one of the ceramic plates is the seal element, the other ceramic plates are respectively provided with water flow holes, and the handle is connected with the seal element. The utility model is characterized in that the three ceramic plates are provided and the intermediate plate is the seal element, an extension site which is connected with the handle is arranged at one side of the seal element, and a rubber seal element and a spring are arranged outside the ceramic plates. The utility model has the advantages of water leakage prevention, long service life, convenient operation, etc.
Description
The utility model belongs to a kind of water supply valve of water supply valve, particularly ceramic closure member of the rotary type closure member with flat sealing surface.
The water supply valve that has similar ceramic closure member of present common use, often be called as ceramic valve, its internal structure is that a pair of ceramic plate that has corresponding water passage hole is arranged on crossing in the middle of the water channel of valve, wherein a slice ceramic plate for fixedly install, another sheet is installed in the rotating shaft as closure member, when the corresponding water passage hole on two ceramic plates during to the dislocation of timing opening of valves, water passage hole valve close, ceramic plate is made by special ceramic material, its surfacing is smooth, and the closed performance of valve is to lean on the plane contact of two ceramic plates to guarantee.Because must entering the water supply chamber at the closure member back side, rotating shaft is connected with closure member, so the bar portion of rotating shaft should be provided with rubber seal, in case the water in water supply chamber leaks from changeing axle portion, but rubber seal is rotated repeatedly with rotating shaft and is prone to wearing and tearing, so valve is not durable, be prone to water from changeing the phenomenon that axle portion leaks.Another problem is that the effect that compresses closure member is also being born in rotating shaft, and this pressuring action is to guarantee that by its head and closely cooperating of valve casing when shaft head and valve casing generation fretting wear, the contact gap of two ceramic plates can increase and occur leaking.
The purpose of this utility model provides a kind of water supply valve that improves the ceramic closure member of structure, can overcome the defective of prior art.
The utility model is achieved in that a kind of water supply valve of ceramic closure member, comprise valve body, the switch handgrip, ceramic plate, rubber seal, the water channel of crossing that intake-outlet is arranged on the valve body and link up intake-outlet, there are screw thread and hexagonal position in the water intake outside, ceramic plate was arranged in the middle of the water channel, it is rotating closure member that a slice ceramic plate is wherein arranged, be equipped with corresponding water passage hole on the ceramic plate, the switch handgrip is connected with closure member, it is characterized in that ceramic plate is three, its intermediate is a closure member, the closure member sidepiece has an elongation position, this elongation position is connected with the switch handgrip by the wall portion port in the middle of the valve body, rubber seal is contained in ceramic plate foreign side, and holddown spring also is equipped with in ceramic plate foreign side.
Such scheme is because ceramic plate is three, intermediate is closure member, and be connected with the switch handgrip by the elongation position of closure member sidepiece, the pivoting friction of the switching process of valve only occurs over just the ceramic plate contact surface like this, other position of other part and valve body does not all produce fretting wear, so just overcome from the phenomenon of switch handgrip and the sluicing of other non-water outlet position, because holddown spring is equipped with in ceramic plate foreign side, so when the ceramic plate contact surface produces wearing and tearing, its contact gap can not increase, and has overcome the problem that the ceramic plate wearing and tearing are leaked like this.Because special cermacis plate contact surface is hard especially smooth, friction is little, so the working life of water supply valve of the present utility model is long especially, opening and closing operations is also very light.
Below in conjunction with accompanying drawing the utility model is done to describe more specifically.
Fig. 1 is the sectional view of a kind of scheme of the utility model.
Fig. 2 is the A-A sectional drawing of Fig. 1.
With reference to Fig. 1～Fig. 2, this water supply valve, comprise valve body 1, switch handgrip 2, ceramic plate 3,4,5, rubber seal 6,7, water intake 8 is arranged on the valve body 1, water outlet 9 and the water channel 10 excessively of linking up intake-outlet, there are screw thread 11 and hexagonal position 12 in water intake 8 outsides, ceramic plate 3,4,5 were arranged in the middle of the water channel 10, wherein ceramic plate 4 is rotating closure member, ceramic plate 3,4, be equipped with water through hole 13 etc. on 5, switch handgrip 2 is connected with closure member 4, feature is that ceramic plate is 3,4,5 three, its intermediate 4 is a closure member, closure member 4 sidepieces have an elongation position 14, elongation position 14 is connected rubber seal 6 by the wall portion port 15 in the middle of the valve body with switch handgrip 2,7 are loaded on ceramic plate 3 respectively, a belleville spring 17 that had water through hole 16 grades also is equipped with in 5 foreign side, the foreign side of ceramic plate 5.In addition, a mandrel 18 also is equipped with at ceramic plate 3,4,5 centers, can keep the concentricity with ceramic plate 3,5 when ceramic plate 4 rotates like this; The installation of ceramic plate 3,4,5, rubber seal 6,7 and spring 17 is to be maintained fixed by compressing of a gland nut 19.Work as water supply valve during use and be in Fig. 1 state, the water through hole 13 excessively between the ceramic plate 3,4,5 etc. aligns one by one, and water supply valve is an opening state; When the moving switch handgrip 2 of plate, closure member 4 rotates, on it cross the mutual dislocation of water through hole excessively of water through hole and ceramic plate 3,5 time, water supply valve is a closed condition.
Claims (3)
