Description

The headstock gear of a kind of improved delayed self-close urinal flushing valve

Technical field

The utility model relates to a kind of flushing valve, and is particularly relevant with the headstock gear of a kind of improved delayed self-close urinal flushing valve.

Background technology

The kind of the time delay self close off type washing valve for toilet of commonly using is more; Angie type is arranged; Straight; Inclined; Horizontal; Tubing type; Foot valve; The multiple style such as urine flushing valve; Below only take structure time delay self close off type washing valve for toilet as shown in Figure 1 as example: comprise valve seat 1; Intake tunnel 2; Time-delay passage 3; The parts such as the control channel 5 of control device 4 controls and exhalant canal 6 form; Be provided with headstock gear 7 in this control channel 5; The opening time length of this headstock gear 7 is by an overrun control 8 controls; When this valve is interfered in no external force; Be in normally off; At this moment; Pressure in the control channel 5 is with quite extraneous; When 4 actions of external force (for example hand) band dynamic control device; Thereby drive sluicing bar 51 actions in the control channel 5; Control channel 5 is communicated with exhalant canal 7; Make the water in the control channel 5 flow to exhalant canal 7 from sluicing bar 51; Then the pressure in the control channel 5 reduces; At this moment; Headstock gear the piston that is provided with the moving vane sheet 73 under the hydraulic pressure of intake tunnel 2, backed down; Intake tunnel 2 is connected with exhalant canal 6; Valve port is in opening; Water just flows out in a large number from exhalant canal 6; At this moment; Remove external force if unclamp hand; Then control device 4 resets under the drive of Compress Spring 41; Thereby driving sluicing bar 51 resets; At this moment; Pressure in the inner chamber 52 of control channel 5 reduces; Then the water in the intake tunnel 2 can (this time-delay passage 3 be for offering from time-delay passage 3 inflow inner chambers 52; Time-delay groove on valve interior wall) water inlet is until external and internal pressure difference balance; The piston that is provided with the moving vane sheet 73 of opening device is resetted, and this flushing valve is in again the sealing inactive state; The time of its time-delay bath is the time that has been full of water in the control channel inner chamber by the time-delay passage, this time-delay washing time length is by an overrun control 8 controls, the set screw of this overrun control 8 for being arranged on the outer wall of control device 4 and penetrating its inner chamber, the structure of above-mentioned urinal flushing valve, its main shortcoming is:the headstock gear of this urinal flushing valve forms by being sealed and matched with the rubber sheet gasket 72 that is driven by sluicing bar 51 with valve seat 1 integrated one copper pad 71, because copper pad is directly to form on 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 pad 71 is bigger with rubber sheet gasket 72 noise in engagement process, and, the rubber pad of said structure cooperates with copper packing, can't adapt to the too high or too low state of hydraulic pressure, because crossing, hydraulic pressure exceeds under the low situation, rubber pad is yielding, this valve is leaked easily, have, control overrun control 8 set screw for being arranged on the outer wall of control device 4 and penetrating its inner chamber of this headstock gear opening time length, the opening time of headstock gear is controlled on the surface that is resisted against piston 73 with its screw bottom that is screwed into inner chamber, the shortcoming of this set is to open a tapped through hole on the outer wall of control device, like this, in use, leak easily at this tapped through hole place.Thus, for defects, the inventor did corresponding the improvement, and headstock gear adopts and is made up of a pair of ceramic limb that is sealed and matched, and wherein, pottery is decided limb and is fixed on the valve seat, and ceramic moving vane sheet is controlled in the control channel mobile by control device; The fixed form that described pottery is decided limb and valve seat is:be provided with screwed hole at valve seat, one copper support ring adheres to this pottery with colloid to be decided limb and is screwed in the described screwed hole, this pottery is decided limb and copper support ring, valve base inner wall all with the bonding location of colloid, said structure shortcoming be processing difficulties, damage easily, and maintenance is also inconvenient.

The utility model content

At above-mentioned defective, the purpose of this utility model is to provide the headstock gear of a kind of improved delayed self-close urinal 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, and be easy to produce, firmly, easy to maintenance.

For reaching above-mentioned purpose, solution of the present utility model is:

The headstock gear of a kind of improved delayed self-close urinal flushing valve, it is arranged in the control channel of this urinal flushing valve, controlling it by a control device opens with closed, and regulate the time that this headstock gear is opened by a delay regulating device, 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, fixed form is: be provided with screwed hole on valve seat, the fixing pottery of one copper support ring is decided limb and is screwed in the described screwed hole, this pottery is decided to be provided with a rubber seal ring between limb and copper support ring and is decided limb with sealed ceramic, copper support ring and valve base inner wall location, ceramic moving vane sheet is controlled it by control device and is moved in control channel.

Described pottery is decided the limb inner chamber and is inwardly protruded out a boss, and copper support ring top outwards protrudes out a boss, and copper support ring extend into pottery and decides the limb inner chamber by means of two boss engaging location.

After adopting said structure, because the headstock gear of delayed self-close urinal flushing valve is cooperated by the two ceramic limbs that are sealed and matched and forms, and two limbs are to process respectively, on assembling 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 described pottery is decided the fixed form of limb and valve seat for affixed by the screw thread of copper support ring and valve seat, and pottery decide to be provided with between limb and copper support ring, and rubber seal ring is decided limb and copper support ring with sealed ceramic and valve base inner wall is located, therefore, its location is more firm, easy to process, also for ease of maintenaince, in addition, because the screw of delay regulating device is arranged in the inner chamber of control device, therefore, this urinal flushing valve can not leaked from this.
