Abstract
The utility model discloses a kind of fore filters, it is characterized in that, including connecting pipe, cylinder with sewage draining exit, it is set to draining valve module at the sewage draining exit and is set to the intracorporal filter core of the cylinder, wherein the connecting pipe is three-port structure and is connected to the cylinder, and the connecting pipe is made of plastics with the metal for being coated on the plastics periphery.The fore filter can be good at the precipitation for guaranteeing not having heavy metal substance such as lead, and can be good at guaranteeing the strainability of fore filter, and filtered water is prevented to be secondarily contaminated；Furthermore the weight that fore filter can be effectively reduced reduces cost, while mitigating weight bearing of the fore filter to water pipe.
Description
Technical field
The utility model relates to a kind of fore filters.
Background technique
As the improvement of people's living standards, requirement of the people to drinking-water is also higher and higher, therefore, people generally can with
Fore filter is installed before water.But the connection of fore filter and inlet and outlet pipe at present, generally connected using copper pipe
It connects.According to common copper material, scorification is easy to cause to go out exceeded and influence water quality；According to low lead bronze, then cost occupies height not
Under；If using plastics instead, it is inadequate to will lead to product strength.
Summary of the invention
In order to solve the above-mentioned technical problem, the purpose of this utility model is to provide a kind of fore filters.
The utility model is achieved through the following technical solutions: a kind of fore filter, including connecting pipe, has blowdown
Mouthful cylinder, be set to draining valve module at the sewage draining exit and be set to the intracorporal filter core of the cylinder, wherein the connection
Pipeline is three-port structure and is connected to the cylinder that the connecting pipe includes plastics and the gold for being coated on the plastics periphery
Belong to.
Preferably, the metal is copper.
Preferably, the junction of the connecting pipe and the cylinder is provided with seal washer.
Preferably, a reversing valve core is equipped in the connecting pipe, the connecting pipe that passes through of a shaft is changed with described
It is connected to spool, the other end of the shaft is equipped with knob.
Preferably, the inner barrel is shape of threads.
It preferably, further include water inlet pipe and water outlet pipe, the inlet pipeline, the outlet pipeline and the connecting tube
Road is to be threadedly coupled.
The fore filter of the utility model can be good at the precipitation for guaranteeing not having heavy metal substance such as lead, and
The strainability that can be good at guaranteeing fore filter, prevents filtered water to be secondarily contaminated；Furthermore due to the connection
Pipeline is combined setting using plastics and metal, and the weight of fore filter can be effectively reduced, and reduces cost, subtracts simultaneously
Light weight bearing of the fore filter to water pipe.
Detailed description of the invention
It, below will be to institute in embodiment or description of the prior art in order to illustrate more clearly of the technical solution of the utility model
Attached drawing to be used is needed to be briefly described, it should be apparent that, the accompanying drawings in the following description is only some of the utility model
Embodiment for those of ordinary skill in the art without creative efforts, can also be attached according to these
Figure obtains other attached drawings.
Fig. 1 is the cross-sectional view of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, to the technical solution in inventive embodiments carry out it is clear,
It is fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole implementation
Example.Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without making creative work
The every other embodiment obtained, fall within the protection scope of the utility model.
Reference book attached drawing 1, the utility model disclose a kind of fore filter, including connecting pipe 1, have blowdown
The cylinder 2 of mouthful c, the draining valve module 21 being set to sewage draining exit c at and the filter core 22 being set in cylinder 2, the wherein connecting tube
Road 1 is three-port structure, including a water inlet 1a, water outlet 1b and connector, which passes through the connector and the cylinder
2 connections, the connecting pipe 1 include plastics 11 and the metal 12 for being coated on plastics periphery, it is preferred that the metal is copper material, i.e.,
It can be moulded in plastic water channel built in copper tube or copper-clad.The junction of the connecting pipe 1 and cylinder 2 is provided with seal washer 3, guarantees
The leakproofness in water route.A reversing valve core 13 is equipped in the connecting pipe 1, a shaft 14 passes through connecting pipe 1 and reversing valve core
13 connections, the other end of the shaft 14 are equipped with knob 15.The fore filter further includes water inlet pipe and water outlet pipe, should be into
Water lines and outlet pipeline are to be threadedly coupled with connecting pipe 1, specifically, the water inlet 1a of the connecting pipe 1 and water outlet
Mouth 1b is respectively provided with external screw thread a 11a and 11b, passes through those external screw threads 11a and 11b with water inlet pipe and water outlet pipe respectively
It is spirally connected.
When the fore filter normal water supply, water flow successively flows into connecting pipe 1 from water inlet 1a, and enters cylinder 2
Filter core 22 be filtered, the water flow for filtering completion is flowed out from the water outlet 1b of connecting pipe 1, in this way, due to water flow be stream
Plastic water channel through connecting pipe can be good at guaranteeing water route in this way there is no being contacted with the metal 12 of its periphery
In do not have the precipitation of heavy metal substance such as lead, and can be good at guarantee fore filter strainability, prevent from filtering
Water afterwards is secondarily contaminated；Furthermore it since the connecting pipe is combined setting using plastics and metal, such as can be used general
Logical copper material is combined, and enhances the bonding strength of fore filter, and the weight of fore filter can be effectively reduced, drop
Low cost, while mitigating weight bearing of the fore filter to water pipe.
Further, the inside of cylinder 2 can be set as shape of threads, to form shape of threads runner, is conducive to generate tangential
In the power of filter core, it is convenient for impurity screening and flushing.
The preferred embodiment of the utility model has shown and described in above description, as previously described, it should be understood that this is practical new
Type is not limited to forms disclosed herein, and should not be regarded as an exclusion of other examples, and can be used for various other groups
Conjunction, modification and environment, and above-mentioned introduction or the technology of related fields can be passed through within the scope of the inventive concept described herein
Or knowledge is modified.And changes and modifications made by those skilled in the art do not depart from the spirit and scope of the utility model, then
It all should be in the protection scope of the appended claims for the utility model.
