Abstract

The utility model relates to a liquid reversal valve particularly suitable for an on-line back flush filtering device having a filter in a liquid flow working system. The utility model provides with two round table-shaped valve cores 1, 2 and two valve bodies 3, 4 which are connected into one body via a pipe axis 5 and a connecting rod 6. The valve cores 1, 2 are provided with an axial arc groove 9 and a radial arc groove 10 which are matched with five inlets and outlets 11, 12, 13, 14, 15 of the valve bodies 3, 4 to realize the function of a two-position five-way valve. The inlets and outlets 12, 14, which are connected with the inlets and outlets of the filter, can carry out back flush for the filter. The utility model with small size and convenient operation can use one valve and one action instead of multi-action by a plurality of assembled valve pipelines to finish the same work.

Description

Split type two-position five-way recoil valve

The utility model relates to a kind of switching valve that is used for controlling liquid stream commutation, is specially adapted to have the operation that online backflushing is washed filter in the flow of liquid Operation System of filter.

In having the flow of liquid Operation System of filter, flow of liquid is admitted to operation field through behind the filter, after filter work a period of time, just residual obstruction may take place, cause device damage and stopping production, therefore often filter is washed with regard to needs, particularly carry out backwash, can remove residue effectively, unimpeded pipeline guarantees to produce and carries out smoothly.In the prior art, the back is manual rinses well in a large amount of still filter being pulled down, and the method for work of this poor efficiency can have a strong impact on production.In some large-scale flow of liquid filtration systems or under special occasions, pulling down filter is very difficult thing, and the device that therefore just has online backflushing to wash filter uses.This device of the prior art is the pipe-line system that is made of a plurality of valve, convert backwash to from normal operation and generally need moving at least 3 valves, operation is trouble very, and a large amount of valves and pipeline will take a lot of spaces, is unsuitable for carrying out apparatus arrangement in the place of compactness and installs.

The purpose of this utility model is intended to propose technical solution according to problems of the prior art, to obtain little, simple in structure, the easy to operate valve of a kind of volume, once to move the same work that replaces a plurality of valve multi-pass operations actions just can finish, enhance productivity, save equipment occupation space.

For achieving the above object, the technical solution that the utility model proposes comprises spool, valve body and the rotating shaft that is connected with spool, valve body is provided with import and export, spool is a garden platform shape, which is provided with ALT-CH alternate channel, this valve is fused by tubular axis and connecting rod by two spools and two valve bodies, the two ends of tubular axis have flange, be connected with bolt with the stub end of spool respectively, the connecting rod of 3 or 4 parallel tubular axis evenly is set around tubular axis, their two is connected with the end of two valve bodies respectively, hold the microcephaly of spool and to connect rotating shaft and pass valve body and stretch to the outside, ALT-CH alternate channel on the spool is an axial arch slot and a radial arch slot, axial arch slot is opened to middle part, spool side from spool big end surface axle center by emission surface, from radially opening one 90 ° curved arc grooves in 180 ° of symmetries of opening at spool side middle part along spool with axial arch slot is radial arch slot, the import and export on the valve body open on three Vertical direction that on the radial arch slot plane are intersection point with the poppet shaft with two Vertical direction on.

Spool 2 phase diagrams when Figure 5 shows that to backwash.

Below in conjunction with Figure of description and embodiment the utility model is done further detailed description: as shown in the figure, the utility model is fused by tubular axis 5 and connecting rod 6 by 1,2 and two

valve bodies

3,4 of two spools, tubular axis 5 two ends have flange 7, stub end with garden platform shape spool 1,2 is connected with bolt respectively, between flange 7 and

valve body

3,4, be provided with seal ring, the microcephaly of spool 1,2 hold connecting rotating shaft 8

pass valve body

3,4 stretch to the outside.The connecting rod 6 of 3 or 4 parallel tubular axis 5 evenly is set around tubular axis 5, their two is adopted with the end of two

valve bodies

3,4 respectively and is threaded, the two ends screw thread of connecting rod 6 is positive and negative tooth, gap between rotation connecting rod 6 can regulate spools 1,2 and the

valve body

3,4, with viscosity and the pressure requirement that adapts to different medium, also can increase the working life after the wearing and tearing, and usually the spool of zero draft post gap is excessive must scrap in wearing and tearing.ALT-CH alternate channel on spool 1,2 is an axial arch slot 9 and a radial arch slot 10, axial arch slot 9 is opened to middle part, spool 1,2 sides by emission surface from spool 1,2 big end surface axis parts, from radially opening one 90 ° curved arc grooves in 180 ° of symmetries of opening at middle part, spool 1,2 sides along spool 1,2 with axial arch slot 9 is radial arch slot 10,90 ° of turnings of the radial arch slot 10 on spool 1 and the spool 2 are opposite direction, with the stub end of spool 1 and spool 2 relative to after rotate 90 ° of installations and promptly constitute state as shown in drawings.The bottom land of arc groove 9,10 is half garden cambered surface, and whole arc groove 9,10 curves for the garden cunning.

Import and export on the

valve body

3,4 that to open on radial arch slot 10 planes with 1,2 of spools be in three Vertical direction of intersection point on 11,12,13 and 2 Vertical direction 14,15.When forward is carried flow of liquid during normal operation, flow of liquid is entered by import 11 shown in Fig. 2,3, radial arch slot 10 on spool 1 flow to the import and export 12 that are connected with the import of filter and sends, through flowing to the import and export 14 on the valve body 4 that is connected with filter outlet after the filter filtration, the radial arch slot 10 on spool 2 flow to outlet 15 and sends into the scene of using; During recoil, rotating shaft 8 is rotated 90 ° shown in Fig. 4,5, washing solution is entered by import 11 equally, axial arch slot 9 through flowing on the spool 2 by tubular axis 5 behind the axial arch slot 9 of spool 1 flow to import and export 14, oppositely through flowing into by importing and exporting 12 behind the filter, the radial arch slot 10 on the spool 1 of footpath is delivered to outlet 13 and is discharged.

Compared with prior art, the utility model volume is little, simple in structure, operation is very convenient, Can replace a plurality of valve pipeline combination multi-pass operation actions just can finish by a valve one-off Same work, improved production efficiency, saved equipment occupation space.
