Description
Technical field
The utility model relates to a kind of for by the valve of the quick emptying of liquid in cell body.
Background technique
Traditional liquid fast-discharge valve 6 as shown in Figure 1, its volume is large, the form of flanges that adopt are arranged on cell body bottom more, the liquid fast-discharge valve 6 of this form is generally to rely on the sealing surface 7 of valve to coordinate to realize sealing with the corresponding circular hole in cell body bottom, therefore the concentricity requirement that liquid fast-discharge valve 6 is installed is very high, precision for assembling is also stricter, if processing and assembling is bad, Leakage probability is very high.And, when leaving standstill for a long time, such fast-discharge valve easily there is micro-leakage phenomenon.
Summary of the invention
The purpose of this utility model is to provide a kind of liquid fast-discharge valve that reduces assembling difficulty.
In order to achieve the above object, the technical solution of the utility model has been to provide a kind of liquid fast-discharge valve, it is characterized in that: comprise coaxially arranged valve casing, spool, valve gap, fast-discharge valve link and base, base is located at the bottom of valve casing and is sealed and matched with it, thereby in valve casing, form seal chamber, one end of spool is positioned at seal chamber through after valve casing, the outer peripheral surface of this end coordinates with the inner wall sealing of seal chamber, thereby seal chamber is divided into upper chamber and lower chambers, upper chamber and lower chambers pass into or derive pressurized air independently of one another via the vent of opening on valve casing, thereby spool is moved up and down, the other end of spool is exposed to outside valve casing, on this end, be provided with valve gap, valve casing is located on fast-discharge valve link, fast-discharge valve link is fixedly connected with cell body in the time of work, have the valve body liquid port of aiming at cell body liquid port at the top of fast-discharge valve link, have valve body liquid outlet in the side of fast-discharge valve link, after spool moves upward and puts in place, by valve gap, valve body liquid port is sealed, thereby by the liquid port sealing of cell body, after spool moves downward and puts in place, valve body liquid port communicates with valve body liquid outlet.
Preferably, described valve casing, spool, valve gap, fast-discharge valve link and base make by anticorrosive material.
Preferably, described anticorrosive material is PVDF or PP or PVC.
Preferably, described valve gap is connected with described spool by concentric threads.
Preferably, described valve casing and described fast-discharge valve link are threaded connection; Described base and described valve casing are threaded connection.
Preferably, the side of described valve gap is the sealing surface with certain taper, and sealing face moves upward and props up the bottom margin of the valve body liquid port of described valve gap after putting in place at described spool.
Preferably, be formed with a circle waterproof step at the top of described valve casing.
The utility model has mainly used the pressure of fluid to realize mechanical motion, thereby realizes the start and stop of valve, completes fast row's function.The utility model is by an overall structure, the sealing surface of fast-discharge valve is not on cell body but at valve body itself, so just greatly reduce the assembling difficulty with cell body, increase the reliability of product, and sealing surface is the conical surface, compare the mode that uses seal ring, greatly reduced the area of dash.Valve gap is made into integral type double-screw bolt and valve body is designed with dash step, has avoided liquid in discharge opeing process to infiltrate valve body.Because of in valve without metalwork, all make by the strong material of the corrosion resistance such as PP or PVDF or PVC the using scope that has greatly increased valve body.In valve body, critical piece is all connected by straight thread, assembles simple and convenient.
With the contrast of traditional liquid fast-discharge valve, the utlity model has following advantage:
One, this fast-discharge valve is made up of resistant material, can be used for using in multiple environment and medium;
Two, the sealing surface of valve gap is the conical surface without with seal ring sealing, greatly reduces dash area; Sealing surface acts on valve body itself and has avoided sealing surface and cell body floss hole need guarantee strict concentric requirement, greatly reduces installation difficulty, and sealing is reliable, is difficult for leaking; Valve gap is that integral type double-screw bolt is connected with spool straight burr, valve body is designed with dash step, prevents that liquid infiltrates valve inner in the process of discharge opeing;
Three, this valve mechanism is simple, and volume is little, makes easily, and cost of production is lower.
Accompanying drawing explanation
Fig. 1 is traditional liquid fast-discharge valve structural representation;
The sectional view of a kind of liquid fast-discharge valve that Fig. 2 provides for the utility model;
Schematic diagram after a kind of liquid fast-discharge valve that Fig. 3 provides for the utility model is installed.
Embodiment
For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
In conjunction with Fig. 2 and Fig. 3, a kind of liquid fast-discharge valve that the utility model provides, comprises coaxially arranged valve casing 1, spool 2, valve gap 3, fast-discharge valve link 4 and base 5.
A kind of liquid fast-discharge valve entirety that the utility model provides is cylindrical, and it is made by the anticorrosive material such as PVDF or PP or PVC, and all parts all can adopt machined into, is very easy to guarantee machining accuracy.
By compressed air gas source, pressurized air is squeezed into lower chambers, thereby bottom chamber pressure increases promotion, spool 2 drives valve gap 3 to move upward, until contact, compress with fast-discharge valve link 4 tops, by valve body liquid port, thereby realize the liquid port that seals up cell body 8, stop liquid to be discharged.And when compressed air gas source, air is squeezed into after upper chamber, the pressure of upper chamber increases, thus promoting spool 2 drives valve gap 3 to move downward, and until expose valve body liquid port, valve body liquid port and the conducting of valve body liquid outlet, discharge liquid fast, realizes fast row function.
