A kind of water tap that is coated with plastic layer
Technical field
The utility model belongs to technical field of taps, relates to a kind of water tap, particularly a kind of water tap that is coated with plastic layer.
Background technique
At present, the valve body of metal faucet generally adopts the brass casting moulding, and casting and mechanical processing technique difficulty are big, the difficult control of quality of product.And along with the development of plastic materials, plastics also more and more are applied in the water tap, the tap valve body that replaces metal to make with the tap valve body of plastic production, but the mechanical strength of the water tap that all-plastic is made is lower, working life is also shorter.
In recent years, the price of copper becomes more and more higher, outside the mechanical strength of the necessity that satisfies water tap, also the manufacture cost of water tap will be lowered, to improve competitiveness of product.
Summary of the invention
The purpose of this utility model is to have above-mentioned problem at existing water tap, and a kind of mechanical strength height, Applicable scope is big, cost the is low water tap that is coated with plastic layer are provided.
The purpose of this utility model can realize by following technical proposal: a kind of water tap that is coated with plastic layer, comprise valve body, handle and be arranged on valve body interior spool and valve rod, one end and the spool of valve rod are connected, the other end passes valve body and handle is connected, described valve body by intake pipe, outlet pipe and be in intake pipe and outlet pipe between body form, it is characterized in that, described body and intake pipe are made by metallic material, be coated with plastic layer at body and intake pipe, outlet pipe is made of plastics and is connected as a single entity with plastic layer.
Originally the water tap that is coated with plastic layer is made valve body by metal and plastics, and spool and valve rod are installed in the body.Intake pipe and body are made by metallic material, therefore, can bear bigger mechanical strength, and coat plastic layer outside intake pipe and body, can save the corrosion protection of intake pipe and this external surface, surface treatment such as anti-oxidation.Outlet pipe is owing to directly communicate with the external world, and the mechanical strength of being born is less relatively, and therefore, it is feasible that outlet pipe adopts plastics to make.Outlet pipe and plastic layer are connected as a single entity, and therefore can be formed by the plastics molding process time processing, have simplified manufacturing process.
In the above-mentioned water tap that is coated with plastic layer, it is copper product that described body and intake pipe adopt metallic material.
In the above-mentioned water tap that is coated with plastic layer, described outlet pipe bends to the right angle and is provided with floor in the bending part.Floor is set strengthens the mechanical strength of outlet pipe.
In the above-mentioned water tap that is coated with plastic layer, described intake pipe has feed-water end, and feed-water end exposes plastic layer, and at feed-water end outside thread is set.Feed-water end exposes plastic layer and conveniently is connected with pipe fitting, and the intensity of connection is provided simultaneously.
In the above-mentioned water tap that is coated with plastic layer, described plastic layer is provided with convex shoulder near the feed-water end place.This convex shoulder can limit to be taken over length and the sealing gasket be screwed into and provides support face.
In the above-mentioned water tap that is coated with plastic layer, described outlet pipe has the water outlet port, is provided with hose coupling on the water outlet port.
Compared with prior art, the intake pipe and the body that originally are coated with the water tap of plastic layer are made by metallic material, can bear bigger mechanical strength.Be coated with plastic layer at body and intake pipe, outlet pipe is made of plastics and is connected as a single entity with plastic layer, can be formed by the plastics molding process time processing, has simplified manufacturing process; Replace with the water outlet pipe plastic, the use of having saved copper product in this water tap has reduced cost.
Description of drawings
Fig. 1 is the structural representation that originally is coated with the water tap of plastic layer.
Among the figure, valve body 1, intake pipe 11, outlet pipe 12, body 13, handle 2, spool 3, seal ring 1, seal ring 25, plastic layer 6, floor 7, water outlet port 8, convex shoulder 9, feed-water end 10, hose coupling 21.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
Originally be coated with the water tap of plastic layer, comprise valve body 1, handle 2 and spool 3 and valve rod 4 in the valve body 1 are set, one end and the spool 3 of valve rod are connected, the other end passes valve body 1 and is connected with handle, valve body 1 by intake pipe 11, outlet pipe 12 and be in intake pipe 11 and outlet pipe 12, between body 13, body 13 and intake pipe 11 are made by copper product, are coated with plastic layer 6 at body 13 and intake pipe 11, outlet pipe 12, are made of plastics and are connected as a single entity with plastic layer 6.
Specifically, intake pipe 11 and body 13 are equipped with spherical spool 3 by being threaded in body 13, for spool 3 is sealed, be provided with seal ring 1 between spool 3 and valve body 1, are provided with seal ring 25 between spool 3 and the intake pipe 11.During installation, earlier seal ring 1 is put into body 13, refill into spool 3 and seal ring 25, then intake pipe 11 and body 13 are tightened.The connecting end of intake pipe 11 is a feed-water end 10, and feed-water end 10 exposes plastic layer 6, and at feed-water end 10 outside thread is set, and plastic layer 6 is provided with convex shoulder 9 near feed-water end 10 places.
Outlet pipe 12, bend to the right angle, for strengthen outlet pipe 12, mechanical strength, outlet pipe 12, the bending part be provided with floor 7.Outlet pipe 12, have water outlet port 8, on water outlet port 8, be provided with hose coupling 21.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as valve body 1, intake pipe 11, outlet pipe 12, body 13, handle 2, spool 3, seal ring 1, seal ring 25, plastic layer 6, floor 7, water outlet port 8, convex shoulder 9, feed-water end 10 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
