Description
Technical field
The utility model relates to a kind of equipment for sedimeter, especially relates to a kind of filter.
Background technology
The filter of prior art is installed between liquid conducting pipes by the Internal Pipe Thread at its two ends; The shell inside of filter is provided with a baffle plate, and the edge of baffle plate is connected with inner wall of tube shell, and baffle plate is in the filter shell, being divided into admission chamber and going out sap cavity; The below of baffle plate is the filter cylinder of filter, in filter cylinder, is provided with screen pack, and the top of screen pack is connected with the baffle plate bottom, and the screen pack edge is connected with the inwall of filter cylinder, and the bottom of filter cylinder is provided with detachable apparatus, and namely screen pack can be taken out and clean.The operation principle of this filter is, runs into baffle plate after carrying liquid to flow to the admission chamber of filter, and due to stopping of baffle plate, liquid changes direction and enters in filter cylinder, by after the screen pack in filter cylinder, flowing to out sap cavity, has so just completed the process of filtration.The shortcoming of this filter is because screen pack is washed away by fluid impact with accumulating over a long period, and screen pack is easy to sustain damage and even ruptures, and service life is not long, needs often to change screen pack.
The utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of screen pack filter in service life that extends.
For achieving the above object, the utility model provides following technical scheme: a kind of filter, comprise valve body, the first screen pack and valve gap, described valve body comprises admission chamber, goes out sap cavity and valve head, the inner chamber of described valve head and the intracavity inter-connection of valve body, the inner chamber of described admission chamber, the inner chamber of valve head and the inner chamber that goes out sap cavity are interconnected and are in the same place with being arranged in order, described the first screen pack is arranged in the inner chamber of valve head, in described the first screen pack, be installed on the second screen pack, the opening of sieve on described the first screen pack and the opening of sieve on the second screen pack stagger mutually.
By adopting technique scheme, the first screen pack is arranged in the inner chamber of valve head, by in the first screen pack, installing the second filter screen, when flow impact the second screen pack, the second screen pack can produce to the first screen pack direction the deformation of certain radian, if deformation obviously can touch the first screen pack, the first screen pack can be given bounce of the second screen pack, make it return to original position, and current intensity of current after the second screen pack has and reduces, impulsive force to the first screen pack reduces, therefore under the acting in conjunction of the first screen pack and the second screen pack, strengthened the intensity of screen pack, extended the service life of filter, in addition, the opening of sieve on the opening of sieve on the first screen pack and the second screen pack staggers mutually, and two screen packs adopt the mesh of different sizes, first filter large particulate matter, refilter finely ground particle substance, improve filter effect, can also control to adjust water yield size and switching in filter.
The utility model further is set to: extension supporting circle on described the first screen pack and valve head contact point.
By adopting technique scheme, bracing ring is set up on the first screen pack and valve head contact point, has increased the contact area of the first screen pack and valve head, helps to improve the intensity of the first screen pack, extends the service life of the first screen pack.
The utility model further is set to: on described valve gap, be provided with the positioning step for the first screen pack and the placement of the second screen pack.
By adopting technique scheme, positioning step is arranged on valve gap, when assembling screen pack and valve gap, the first screen pack and the second filter screen can be placed on positioning step, guarantee the accuracy of assembling, also prevent the lower shake in working order of the first screen pack and the second filter screen.
The utlity model has following advantage: the first screen pack is arranged in the inner chamber of valve head, by in the first screen pack, installing the second filter screen, under the acting in conjunction of the first screen pack and the second screen pack, strengthened intensity and the filter effect of screen pack, extended the service life of filter.
The accompanying drawing explanation
Fig. 1 is the structure cutaway view of the utility model filter;
Fig. 2 is the structure cutaway view of its screen pack of filter shown in Figure 1.
In figure: 1, valve body; 2, the first screen pack; 3, admission chamber; 4, the second screen pack; 5, go out sap cavity; 6, valve head; 7, opening of sieve; 8, bracing ring; 9, positioning step; 10, valve gap.
The specific embodiment
Referring to figs. 1 through shown in Figure 2, the filter of the present embodiment, comprise valve body 1, the first screen pack 2 and valve gap 10, described valve body 1 comprises admission chamber 3, goes out sap cavity 5 and valve head 6, the intracavity inter-connection of the inner chamber of described valve head 6 and valve body 1, the inner chamber of the inner chamber of described admission chamber 3, valve head 6 is interconnected and is in the same place with being arranged in order with the inner chamber that goes out sap cavity 5, described the first screen pack 2 is arranged in the inner chamber of valve head, in described the first screen pack 2, be installed on the second screen pack 4, the opening of sieve 7 on described the first screen pack 2 and the opening of sieve 7 on the second screen pack 4 stagger mutually.
By adopting technique scheme, the first screen pack 2 is arranged in the inner chamber of valve head 6, by in the first screen pack 2, installing the second filter screen 4, when flow impact the second screen pack 4, the second screen pack 4 can be to the deformation of the first screen pack 2 directions generation certain radian, if deformation obviously can touch the first screen pack 2, the first screen pack 2 can be to 4 one bounces of the second screen pack, make it return to original position, and current intensity of current after the second screen pack 4 has and reduces, impulsive force to the first screen pack 2 reduces, therefore under the acting in conjunction of the first screen pack 2 and the second screen pack 4, strengthened the intensity of screen pack, extended the service life of filter, in addition, the opening of sieve 7 on the opening of sieve 7 on the first screen pack 2 and the second screen pack 4 staggers mutually, and two screen packs adopt the mesh of different sizes, first filter large particulate matter, refilter finely ground particle substance, improve filter effect, can also control to adjust water yield size and switching in filter.
