Compared with prior art, the utility model is mainly in the valve gap that connects blowdown chamber, to arrange one can move axially and spacing spool along valve gap axial line, this spool can possess quick connection and self-sealing function in moving axially process, thereby realized opening fast and automatically closing of filter dirt eliminating function, this drain filter structure can avoid traditional drain filter need first blind off a line when the inner impurity of discharge line, again filter valve gap is opened to clear up the trouble of impurity, can effectively improve the operational efficiency of pipeline medium, can reduce again the cost of labor of dismounting filter blowdown, but also the selection that has increased blowdown end connection device is installed or unloads, increased the security of equipment operation.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present utility model (the self sealss closed condition that connects antifouling cover).
Fig. 2 is sectional structure schematic diagram of the present utility model (open mode that connects blowoff valve).
The specific embodiment
To the utility model embodiment, elaborate again by above-mentioned accompanying drawing below.
As shown in Figure 1 and Figure 2,1. triple-valve body, 11. snout cavities, 12. outlet plenums, 13. blowdown chambeies, 2. valve gap, 21. valve pockets, 3. Compress Spring, 4. spool, 41. inner chambers, 42. mudholes, 43. "O"-rings, 44. circlips, 5. antifouling cover, 6. seal washer, 7. actinal surface packing ring, 8. screen tube, 9. blowoff valve.
Fast interface drain filter, as shown in Figure 1, it is a kind of is arranged in pipe-line system and for the filter of impurity in discharge line fast, its structure is mainly to consist of triple-valve body 1, screen tube, valve gap 2, spool 4 and Compress Spring 3 etc.
Described triple-valve body 1 is " Y " type triple-valve body often adopting in filtration device structure, in this triple-valve body, be provided with the snout cavity 11, outlet plenum 12 and the blowdown chamber 13 that interconnect, snout cavity 11 is wherein with outlet plenum 12 on same axial line, and the axial line of the axial line in blowdown chamber 13 and above-mentioned two chambers tilts at an angle.Simultaneously, the port part of these three chambers is equipped with internal thread, wherein the internal thread of snout cavity 11 is mainly used in external inlet pipeline, internal thread for the entering of liquid medium in inlet pipeline, outlet plenum 12 is mainly used in external outlet conduit, outflow for liquid medium in outlet conduit, and the internal thread in blowdown chamber 13 is mainly used in external valve gap 2, on the excircle end face that this valve gap contacts with blowdown chamber 13 ports of export, be also provided with actinal surface packing ring 7, to strengthen the sealing property connecting between the two.
In described blowdown chamber 13, be provided with a screen tube 8, this screen tube is a cylindrical structure that both ends of the surface connect, the axial line in itself and blowdown chamber 13 is overlapping position relationship, screen tube 8 one end are inlaid in the installation annular groove of triple-valve body 1 inner face, the other end is inlaid in the installation annular groove of valve gap 2 inner faces, therefore the screen tube 8 after installing can block inlet chamber 11 with blowdown chamber 13 between be communicated with, but blowdown chamber 13 and outlet plenum 12 can be sealed, be that the liquid medium that snout cavity 11 flows into must could be discharged from outlet plenum 12 after screen tube 8 filtrations in blowdown chamber 13, impurity after filtering is discharged by the port of export in blowdown chamber 13.
In described valve gap 2, have the valve pocket 21 that front and back ends connects, this valve pocket and blowdown chamber 13 are on same axial line, and described valve pocket 21 is interior to be arranged one and can make axially movable spool 4 along axial line; In described spool, be provided with inner chamber 41, this inner chamber front end seals, rear end is open-minded, is provided with the mudhole 42 of four circumference uniform distributions, the equal communication with cavity 41 of each mudhole on the outer circumference surface of spool 4 leading sections; Described spool 4 leading sections also stretch out valve gap 2 front ends and enter in blowdown chamber 13, on spool leading section, be embedded with circlip 44, using as the axially movable limit element of spool 4, and on the outer circumference surface that spool 4 contacts with valve gap 2, be embedded with "O"-ring 43, mainly as spool 4, when moving, valve gap 2 forms radially self-packing dynamic seal; Described spool 4 rear end faces are provided with seal washer 6, as the seal connector of gas thread end face; The described outer Compress Spring 3 that is provided with suit connection of spool 4, the two ends difference pushing tow of this Compress Spring is on the interior shoulder of valve gap 2 and the outer shoulder of spool 4, therefore make spool 4 possess all the time a mobile pre-thrust backward under the elastic force effect of Compress Spring 3, and valve core cavity 41 under this state is to be connected with the valve pocket 21 in valve gap 2 by mudhole 42.
Described valve gap 2 ports of export are provided with the blowoff valve 9 being tightly connected or are provided with the also antifouling cover 5 of closeding valve cavity that is tightly connected, this blowoff valve 9 can be selected the equipment for opening and closing such as ball valve, gate valve or water nozzle, after connecting above-mentioned blowoff valve, the elastic force that can pushing tow spool 4 overcomes Compress Spring 3 by blowoff valve 9 moves forward, and then make mudhole 42 be communicated with respectively blowdown chamber 13 and inner chamber 41, the impurity in blowdown chamber 13 just can emit from external blowoff valve 9 fast by spool 4.
The utility model is mainly controlled blowoff valve 9 classes such as the automatic-sealed of spool 4 and mounting ball valve, gate valve, water nozzle opening and closing device by the resilience of original state lower compression spring 3 is so that the automatic unlatching of spool 4 is controlled in Compress Spring 3 compressions, thereby better realizes self sealss and the Rapid pollution discharge of drain filter.
The above is only better embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
