Description

Vacuum closet discharging device

Technical field:

The present invention relates to a kind of flushing device of handling water storage tank with pressure, particularly a kind of vacuum toilet of having.

Background technology:

The vacuum closet control element of existing vacuum toilet mostly adopts electronic component, but because the environment for use humidity, electronic component damages easily, causes its functional performance extremely unstable, and the practicality of these devices is quite queried; To this, the dealer once developed the employing pneumatic control components, and also because complex structure, assembling and problem such as difficult in maintenance cause it to be difficult to apply; At the problems referred to above, the Chinese patent name is called " a kind of vacuum toilet ", the patent No. is 00223791.1, new technical scheme is proposed, this scheme includes starting drive, control device, vacuum closet and vacuum collecting dung jar, wherein: starting drive by release the button and emergency button form, releasing the button is that a displacer is connected with control device, it resets is to adopt back-moving spring simply; Control device, be formed with some air chambers in its housing, one push rod runs through each air chamber, major and minor valve is packed on the push rod successively, the push rod top is provided with return spring, and holds on housing, cooperates each air chamber air-flow, the drain valve of vacuum closet and flushing valve are closed under the return spring effect to finish one work period of control device; Vacuum closet is by drain valve, flushing valve and closet are formed, drain valve structure and the United States Patent (USP) (patent No. 3,984,080) structure is basic identical, no longer describe in detail, its flushing valve structure is similar with Sweden product E VAC, advancing of this product, delivery port is controlled it by diaphragm piston and is led to, disconnected, the action of this diaphragm piston is: with the adhesive of control device chamber vacuum degree and fitting piston rubber membrane and magnet assembly, open diaphragm piston, intake-outlet passes to the disappearance of above-mentioned vacuum, under action of reset spring, makes the reposition of piston rubber membrane, magnet assembly separates, close diaphragm piston, intake-outlet is disconnected, and another architectural feature of this product is that air chamber and water cavity are made up of respectively two housings; There is following point in technique scheme:

1. though it is simple in structure to release the button, its reset (being to cut off after force feed gas reaches control device) is to be finished by back-moving spring, realize haveing nothing to do with the control device function, do not have the function of feed back control system action, thereby bring negative effect for actions such as follow-up bath, discharging;

2. the key member push rod and the return spring thereof of control device, its acting force of the spring, the directly unlatching of the major and minor valve of influence or close, and the function of related each air chamber, because this is the steady state value that can't adjust as power, the deviation of any processing, assembling, material all may influence the action of push rod, thereby influences the validity of subsequent components functions such as flushing valve, drain valve;

3. flushing valve only relies on vacuum and the open and close of back-moving spring control diaphragm piston, because its function is limited, causes the heavy of flushing valve, may cause unstable properties, and suction is unclean, and water consumption also increases.

Summary of the invention:

Technical problem to be solved by this invention is, a kind of improved vacuum closet discharging device is provided, and it can improve the function of opening of device and control effectively, improve the sensitivity of flushing valve, guarantee stable equipment operation, the suction effect is further improved, and water consumption reduces.

The technical scheme that the present invention solves the problems of the technologies described above employing is: vacuum closet discharging device includes actuating mechanism, executing agency, flushing valve, vacuum closet, vacuum discharge valve and collection cabinet, actuating mechanism is connected with executing agency through pipeline, executing agency is connected with flushing valve and vacuum discharge valve respectively through pipeline, flushing valve is connected with vacuum closet through pipeline, vacuum closet is connected with the vacuum discharge valve and collects cabinet through pipeline, be characterized in: the cylinder body of the actuating mechanism of exhaust apparatus is provided with the reset assembly that is connected with the executing agency vacuum source, the rear end of executing agency's push rod of exhaust apparatus is provided with the restoring force adjusting part, be provided with back-moving spring in the air chamber L of the flushing valve connection atmosphere of exhaust apparatus, back-moving spring one end is held in the spring pedestal of upper shell, and the back-moving spring other end is held in the diaphragm piston of valve module.

The gap that meat and fish dishes flows for air is set between the spring pedestal of flushing valve upper shell and guide way and guide that cooperates and the air chamber loam cake.

The information of the reset assembly feedback executing agency of actuating mechanism of the present invention, the restoring force that acts on the push rod of executing agency (spring force) is adjustable, all can improve the function of follow-up bath, discharging, the setting of the strong back-moving spring of flushing valve and the effect of air flow gap, all can make the sensitivity of flushing valve that great raising is arranged, its synthesis result, the present invention can make the overall performance of vacuum discharge equipment have a greater degree of improvement, thereby make the runnability of equipment more stable, the suction better effects if, and more can using water wisely.
