Abstract
The utility model relates to a gate valve, including the valve body, be equipped with fluid passage in the valve body, be equipped with the flashboard that can block fluid passage on the valve body, be equipped with the handle that is connected to the flashboard on the valve body, fluid passage both ends outside all extends the outer takeover that has with other pipe fittings fixed connection, the valve body is including the stainless steel layer of arranging the inlayer in and the plastic layer of living the stainless steel layer through the cladding of moulding plastics. The present case has anticorrosively, and is longe -lived, and the valve body is light, advantages such as easy installation.
Description
[technical field]
The utility model is about a kind of gate valve.
[background technique]
Due to existing various valve body, particularly gate valve.Gate valve on the existing pipeline being used in transmission sky fuel gas tube or other gas, this kind of gate valve is generally adopt cast iron or cast steel, also has the gate valve of all-plastic.If adopt be full cast iron or cast steel to manufacture gate valve, then this valve body is not only heavy, and will spray one deck corrosion resistant coating again on the surface of valve body, then is embedded in underground or water.Install difficulty, the life-span is short, perishable, can only pass through Flange joint when being connected with pipeline.
In addition, if adopt the gate valve of all-plastic, then the pressure born inside valve body is very high, and receiving a mandate of valve body is not long, and the pressure inside pipeline can not be too high.
[model utility content]
The purpose of this utility model overcomes the deficiencies in the prior art and provides a kind of anticorrosion, and the life-span is long, and valve body is light, easy-to-install gate valve.
For above-mentioned purpose, the utility model by the following technical solutions:
A kind of gate valve, it is characterized in that comprising valve body 1, fluid passage 2 is provided with in valve body 1, valve body 1 is provided with the flashboard 3 that fluid passage 2 can be blocked, valve body 1 is provided with the handle 4 being connected to flashboard 3, the outside of two ends, described fluid passage 2 is all extended with the externally connected pipe 13 be fixedly connected with other pipe fitting, and described valve body 1 includes the stainless steel layer 11 being placed in internal layer and the plastic layer 12 being enveloped stainless steel layer 11 by injection moulding.
A kind of gate valve as above, is characterized in that described plastic layer 12 is PE plastic layer.
A kind of gate valve as above, is characterized in that described PE plastic layer is the PE material plastic layer of middle and higher density.
A kind of gate valve as above, is characterized in that the thickness of described stainless steel layer 11 is 2-3mm.
A kind of gate valve as above, is characterized in that the diameter of described externally connected pipe 13 is 90-630mm.
The beneficial effects of the utility model have:
The valve body of this case is adopted and is placed in the stainless steel layer of internal layer and is enveloped the plastic layer of stainless steel layer by injection moulding.Such employing stainless steel layer as internal layer, then adopts plastic layer as skin.Such stainless steel internal layer can bear the immense pressure in pipeline, and pressure-bearing the highest in chamber can reach 16 barometric pressure.
Adopt plastic cement outer again, wherein a kind of effect is exactly light quality, is easy to carrying and installs.Antisepsis is played in effect in addition, and the life-span is long, and its life time reaches 50 years.
Stainless steel lining and plastic cement skin combine, and it is lightweight, is convenient to install and use, and save cost.
Also have the skin of its externally connected pipe to be that plastic cement PE is outer, then, when being connected with other pipe fitting, putting a heat and melting the heat adding thermal weld and melt cover and just can realize connection.
[accompanying drawing explanation]
Fig. 1 is schematic diagram of the present utility model.
[embodiment]
Below in conjunction with accompanying drawing and embodiment, the utility model is elaborated:
As shown in the figure, a kind of gate valve, comprise valve body 1, fluid passage 2 is provided with in valve body 1, valve body 1 is provided with the flashboard 3 that fluid passage 2 can be blocked, valve body 1 is provided with the handle 4 being connected to flashboard 3, drives moving up and down of flashboard 3 by rotating handles 4, thus realize the function of flashboard 3 block fluid passage 2, realize throttle down.The outside of two ends, described fluid passage 2 is all extended with the externally connected pipe 13 be fixedly connected with other pipe fitting.Described valve body 1 includes the stainless steel layer 11 being placed in internal layer and the plastic layer 12 being enveloped stainless steel layer 11 by injection moulding.Be placed in the stainless steel layer of internal layer because valve body 1 adopts and enveloped the plastic layer of stainless steel layer by injection moulding.Such employing stainless steel layer as internal layer, then adopts plastic layer as skin.
As preferred embodiment, described plastic layer 12 is PE plastic layer.Further, described PE plastic layer is the PE material plastic layer of middle and higher density.Wherein a kind of effect of this plastic layer is exactly light quality, is easy to carrying and installs.Antisepsis is played in effect in addition, and the life-span is long, and its life time reaches 50 years.Stainless steel lining and plastic cement skin combine, and it is lightweight, is convenient to install and use, and save material, save cost.
As preferred embodiment, the thickness of described stainless steel layer 11 is 2-3mm, and the thickness of plastic layer 12 will be thicker than the thickness of stainless steel layer 11.Such stainless steel internal layer can bear the immense pressure in pipeline, and pressure-bearing the highest in chamber can reach 16 barometric pressure.
As preferred embodiment, the diameter of described externally connected pipe 13 is 90-630mm.Therefore this case can relate to the valve body of various different model size.
