Abstract
The utility model relates to a headstock gear of a flushing valve, which is arranged in the control channel of the flushing valve and controlled to be opened and closed by a control device. The headstock gear is composed of a pair of seal-matched ceramic blades, a fixed ceramic blade is fixed to a valve base, and a movable ceramic blade is controlled to move in the control channel by the control device, wherein the valve base is provided with a thread hole, and a copper support ring is adhered to the fixed ceramic blade by colloid and screwed into the thread hole. The fixed ceramic blade, the copper support ring and the inner wall of the valve base are all adhered and positioned by colloid, and the entire processing of the ceramic fixed blade is convenient. Besides, the ceramic has the performance of abrasion resisting, high-temperature resisting and low-temperature resisting and long lifetime. The utility model can also be used in the status of high or low hydraulic pressure and has low noise. The fixing mode of the fixed ceramic blade makes the position of the fixed ceramic blade much firmer.
Description
The utility model relates to a kind of flushing valve, and is particularly relevant with a kind of headstock gear of flushing valve.
The kind of the flushing valve of commonly using is more; Angie type is arranged; Straight; Inclined; The multiple style such as urine flushing valve; Below only take structure flushing valve as shown in Figure 1 as example: comprise valve seat 1; Intake tunnel 2; The parts such as the control channel 4 of control device 3 controls and exhalant canal 5 form; Be provided with headstock gear 6 in this control channel 4; The headstock gear of this toilet flushing valve forms by being sealed and matched with the rubber sheet gasket 62 that is driven by piston 63 with valve seat 1 an integrated copper gasket 61; Said structure is because copper gasket is directly to form at valve seat; And; Quality of fit is had relatively high expectations; So be difficult for processing; And; The headstock gear of this structure; In use; Because the poor-performing of corrosion-resistant and the high temperature resistant and low temperature of rubber; Difficult adaptation quenching; Shock heating working environment; And the life-span is relatively low; In addition, copper gasket 61 is bigger with rubber sheet gasket 62 noise in engagement process, and; The rubber blanket of said structure cooperates with copper packing; Can't adapt to the too high or too low state of hydraulic pressure, to exceed in the low situation rubber blanket yielding because hydraulic pressure is crossed, and this valve is leaked easily.
At above-mentioned defective, the purpose of this utility model is to provide a kind of headstock gear of flushing valve, its have be easy to process, the life-span is long, anti-ly leak, noise reduction and performance high temperature resistant, low temperature.
For reaching above-mentioned purpose, solution of the present utility model is:
A kind of headstock gear of flushing valve, it is arranged in the control channel of this urinal flushing valve, controlling it by a control device opens with closed, described headstock gear is made up of a pair of ceramic limb that is sealed and matched, wherein, pottery is decided limb and is fixed on the valve seat, and ceramic moving vane sheet is controlled it by control device and moved in control channel.
The fixed form that described pottery is decided limb and valve seat is: be provided with screwed hole on valve seat, one copper support ring adheres to this pottery with colloid to be decided limb and is screwed in the described screwed hole, and this pottery is decided limb and copper support ring, valve base inner wall all with the bonding location of colloid.
After adopting said structure, form because the headstock gear of flushing valve is cooperated by the two ceramic limbs that are sealed and matched, and two limbs are to process respectively, on assembling again, therefore, it is convenient to processing, also be convenient to loading and unloading, and because pottery has performance wear-resisting and high temperature resistant, low temperature, therefore, life-span is longer, and in addition, the ceramic gasket of this kind structure cooperatively interacts, applicable to the too high or too low situation of hydraulic pressure, make its antileaking, and owing to be the fitted seal of two ceramic limbs, therefore, noise is less; And the fixed form that described pottery is decided limb and valve seat is for affixed by the screw thread of copper support ring and valve seat, and ceramicly decides limb and copper support ring, valve base inner wall all with the bonding location of colloid, and therefore, its location is more firm.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a plan cross-section schematic diagram of commonly using product of the present utility model;
Fig. 2 is the plan cross-section schematic diagram of the utility model embodiment;
Fig. 3 is the action plane cross-sectional schematic of the utility model embodiment; Label: 1-valve seat; 11-screwed hole; 2-intake tunnel; 3-control device; 4-control channel;
5-exhalant canal; The headstock gear of 6-prior art; 61-copper pad;
62-rubber sheet gasket; 7-headstock gear; 71-pottery is decided limb;
72-ceramic moving vane sheet; 73-piston; 74-copper support ring.
Headstock gear of the present utility model can be arranged on multiple prolonging in the flushing valve; As: angie type; Straight; Horizontal; Inclined; In the multiple flushing valve such as urinal valve; See also Fig. 2; Figure 3 shows that example describes the utility model; A kind of embodiment that provides for the utility model; Its structure is: comprise valve seat 1; Intake tunnel 2; The parts such as the control channel 4 of control device 3 (control device among the embodiment is a control depression bar) control and exhalant canal 5 form; Be provided with headstock gear 7 in this control channel 4; Described headstock gear 7 is made up of a pair of ceramic limb that is sealed and matched; Wherein, Pottery is decided limb 71 and is fixed on the valve seat 1; On the piston 73 that pottery moving vane sheet 72 is arranged in the control channel 4; It moves in control channel 4 by control device 3 controls; The fixed form that described pottery is decided limb 71 and valve seat 1 is: be provided with screwed hole 11 at valve seat 1; One copper support ring 74 adheres to this pottery with epoxy resin to be decided limb 71 and is screwed in the described screwed hole 11, and this pottery is decided limb 71 and copper support ring 74; Valve seat 1 inwall is all located with epoxy resin bonding.
Be provided with the flushing valve of above-mentioned headstock gear 7, when it is interfered in no external force, be in normally off, when external force action control system 3 and drive ceramic moving vane sheet 72 and move axially, valve port is in opening, and intake tunnel 2 is communicated with exhalant canal 5, and water just flows out in a large number from exhalant canal 7, finish the flushing action, at this moment, if unclamping hand removes external force, this moment, button 4 resetted under the drive of compression spring, piston 73 is closed fully, and this flushing valve is remained static again; Because the headstock gear of flushing valve is cooperated by the two ceramic limbs that are sealed and matched and forms, and two limbs are to process respectively, assemble again, therefore, it is convenient to processing, also is convenient to loading and unloading, and because pottery has performance wear-resisting and high temperature resistant, low temperature, therefore, the life-span is longer, in addition, the ceramic gasket of this kind structure cooperatively interacts, applicable to the too high or too low situation of hydraulic pressure, make its antileaking, and owing to be the fitted seal of two ceramic limbs, therefore, noise is less; And the fixed form that described pottery is decided limb and valve seat is for affixed by the screw thread of copper support ring and valve seat, and ceramicly decides limb and copper support ring, valve base inner wall all with the bonding location of colloid, and therefore, its location is more firm.
The foregoing description only is a kind of embodiment of the present utility model; in use; headstock gear of the present utility model also can be used in the flushing valve of multiple style; straight formula, horizontal, a lot of styles such as urinate flushing valve, inclined etc.; as long as satisfying, its headstock gear forms by a pair of ceramic limb that is sealed and matched; wherein, pottery is decided limb and is fixed on the valve seat, and it is the scope of the utility model protection that ceramic moving vane sheet is controlled it mobile in control channel by control device.
