Abstract
The utility model discloses a vacuum gate valve, which relates to a gate valve for controlling the opening and closing of a vacuum pipeline. The vacuum gate valve is provided with a valve body, wherein the valve body is provided with a sewage inlet and a sewage outlet, wherein a through sewage flow channel is formed between the sewage inlet and the sewage outlet; a sliding chute which vertically intersects with the sewage flow channel is formed in the valve body; a flashboard is arranged in the sliding chute; the front end part of the flashboard is provided with an air guide port; the sliding chute at the front end of the flashboard is always communicated with the sewage inlet through the air guide port; a return spring is arranged between the back end of the flashboard and the valve body; and the valve body on the back side of the flashboard is provided with a control port. During installation, the vacuum gate valve is arranged on a suction pipeline of a vacuum system, and the control port is connected with the atmospheric air and a vacuum source respectively through a reversing valve. The gate valve is in a normally-closed state, the reversing valve is controlled to isolate the atmospheric air while the sliding chute in the valve body is communicated with the vacuum source when the valve body is required to be opened, and the flashboard rapidly slides backwards by overcoming spring force under the action of vacuum force, so that the sewage inlet and the sewage outlet are opened and communicated immediately. The valve has the advantages of high opening and closing speeds, low energy consumption, freeness from blockage, small size, low cost and high reliability.
Description
Technical field
Type of the present invention relates to vacuum gate valve, says it is the vacuum gate valve that is used for the control of vacuum line break-make that a kind of vacuum sewage system uses in detail.
Background technique
At present, the lifting of underground sewage discharging mainly contains two kinds of approach, and the one,, rely on sewage pump that sewage is promoted and discharge; The 2nd,, grew up in recent years, utilize vacuum system that sewage is promoted the method that discharge through sewage pump the back rapidly.The valve that is used for controlling automatically the sewage break-make in the vacuum system is the bottleneck of puzzlement equipment development always; Because the speed of sewage is very fast in the vacuum system; The dirt of bulk often occurs; Common electric valve, the butterfly valve class is stopped by valve plate easily and extension is stained with, and rag, sanitary napkins class foreign material can't pass through at all; Gate valve class mortor operated valve, owing to be lead screw transmission, opening speed is too slow, and dirt just has been stuck in valve port when half-open, and is not only unimpeded inadequately but also cause the waste of a large amount of degree of vacuum, and the size of this type of valve is too big simultaneously, and installing space is restricted; The passage of stop valve class all is the form of turning round, and dirt blocks more easily, can not use at all.
Summary of the invention
The objective of the invention is to solve the deficiency of above-mentioned existing technology, a kind of simple in structure, opening speed is fast, manufacturing cost and use cost is cheap vacuum gate valve is provided.
The present invention solves the problems of the technologies described above the technological scheme that is adopted:
A kind of vacuum gate valve is provided with valve body, and valve body is provided with sewage import and outlet of sewer; It is characterized in that being straight-through type sewage runner between interior sewage import of valve body and the outlet of sewer, be provided with the chute that intersects vertically with the sewage runner in the valve body, be provided with the flashboard of separating the sewage runner in the chute; The flashboard front end is provided with air guide port; Air guide port makes the chute of flashboard front end keep constantly being communicated with the sewage import, is provided with Returnning spring between flashboard rear end and the valve body, and the valve body of flashboard rear side is provided with the control mouth.
Valve body described in the present invention is combined through attachment screw by upper valve body, following valve body, left end cap and right end cap.Be convenient to processing, assembling and the maintenance of gate valve.
During installation, the present invention is installed on the suction line of vacuum system, will controls mouth and be connected with vacuum source with atmosphere respectively through selector valve.In the use, this gate valve is a normally off, and selector valve is with chute in the valve body and air communication, and flashboard slides into an end of chute the sewage runner in the valve body is separated cut-out under the effect of Returnning spring; When valve need be opened, the control selector valve cut off atmosphere and simultaneously the chute in the valve body is communicated with vacuum source, and flashboard overcomes spring force under the effect of vacuum power the back is sliding rapidly, and the sewage inlet/outlet is opened connection immediately.This valve opening and closing speed is fast, and energy consumption is low, and is clog-free, and size is little, and cost is low, and reliability is high.The flashboard front end is provided with air guide port, and air guide port has reduced the area of contact of flashboard front end, and the chute front end be difficult for to form vacuum, and the convenient flashboard that promotes judges whether spring situation and resistance to motion size be normal when assembling and maintenance simultaneously.Salient point of the present invention is that the sewage inlet/outlet is very unimpeded, and valve is difficult for blocking, and switch is rapid, saves the energy, the convenient making simple in structure, and the reliability height is not fragile, and size is exquisite, makes things convenient for installation and maintenance, is specially adapted to the break-make control of vacuum line.
