Abstract
The utility model discloses a sealed face spray-welding carbide's high temperature resistant wear-resisting anticorrosive plug valve, including valve body, cock core, gland, plug pulling bolt and handle, valve body wall thickness is increased by the 6.5mm of former specification and is 13mm, and the sealed face spray-welding of cock core has the one deck carbide material. The plug valve is simple in structure, environment pollution caused by leakage of media from the bottom of the valve body can be effectively avoided, the wall thickness of the valve body wall is increased, a layer of hard alloy material is sprayed and welded on a sealing surface, erosion resistance and corrosion resistance are greatly improved, the plug valve is more durable, and the requirements of economy and environment are met.
Description
Technical Field
The utility model relates to a fluid control valve field, especially a sealed face spray welding carbide's high temperature resistant wear-resisting anticorrosive stainless steel plug valve.
Background
The plug valve is a valve which realizes opening and closing by rotating the valve core by 90 degrees to lead the passage port on the valve core to be communicated with or separated from the passage port on the valve body. The main application is in chemical industry enterprise, uses the medium corrosivity strong in chemical industry enterprise to under the operating mode condition of high temperature, taking the particulate matter, there is the drawback in current ordinary stainless steel plug valve, because stainless steel hardness is not high, can not resist the special operating mode condition of chemical industry enterprise, causes plug valve life not long.
In addition, the valve body wall thickness of the conventional common plug valve is generally 6.5mm, and the common plug valve cannot adapt to severe working conditions and cannot be durable due to the thin wall thickness, so that the continuous operation requirement of a chemical industry enterprise is met.
Disclosure of Invention
The utility model provides a solve the easy seepage of the plug valve medium that exists among the prior art and can not durable problem, and provide a sealed face spray welding carbide's high temperature resistant wear-resisting anticorrosive plug valve.
The technical scheme of the utility model as follows: a high-temperature-resistant, wear-resistant and corrosion-resistant plug valve with a sealing surface spray-welded with hard alloy comprises a valve body 1, a plug core 2, a packing gland 3, a plug pulling bolt 5 and a handle 7. The improved valve is characterized in that a first connecting pipe 9 and a second connecting pipe 10 are arranged on two sides of the valve body 1, a packing gland 3 is arranged right above the valve body 1, a cock core 2 is arranged in a valve cavity in the middle of the packing gland 3, a plug pulling bolt 5 is additionally arranged in the middle of the cock core 2, the wall thickness of a valve body wall 6 of the first connecting pipe 9 and the wall thickness of a valve body wall 6 of the second connecting pipe 10 are increased to 13mm from 6.5mm of the original specification, and a layer of hard alloy material is spray-welded on a sealing surface 8 of the.
Use the utility model discloses a sealed face spray welding carbide's high temperature resistant wear-resisting anticorrosive plug valve, medium corrosivity strong when using in chemical industry enterprise, and the operating mode condition is under the condition of high temperature, taking the particulate matter more, even valve body and stopper wearing and tearing back, change into the plug pulling bolt of valve body top by the back race bolt of valve body bottom before. Can prevent the medium from leaking from the bottom of the valve body, causing environmental pollution and even hurting operators. Additionally, the utility model discloses a sealed face spray welding carbide's high temperature resistant wear-resisting anticorrosive plug valve has increased the wall thickness of valve body wall to at the sealed face spray welding one deck carbide material of cock core, erosion-resistant corrosion resisting property has obtained very big improvement, and coefficient of friction is little, and durable more guarantees chemical industry enterprise's continuous operation requirement, has satisfied the requirement of economy, environment.

Fig. 1 is a schematic view of the overall structure of the plug valve of the present invention.
Figure 2 is a schematic structural view of the cock core of the present invention.
In the figure: 1. the plug valve comprises a valve body, 2, a plug cock core, 3, a packing gland, 4, a valve body bottom, 5, a plug pulling bolt, 6, a valve body wall, 7, a handle, 8, a sealing surface, 9, a first connecting pipe, 10 and a second connecting pipe
Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
The utility model discloses as shown in fig. 1, a sealed face spray welding carbide's high temperature resistant wear-resisting anticorrosive plug valve comprises valve body 1, cock 2, gland 3, plug pulling bolt 5 and handle 7.
The improved valve is characterized in that a first connecting pipe 9 and a second connecting pipe 10 are arranged on two sides of the valve body 1, a packing gland 3 is arranged right above the valve body 1, a cock core 2 is arranged in a valve cavity in the middle of the packing gland 3, a plug pulling bolt 5 is additionally arranged in the middle of the cock core 2, the wall thickness of a valve body wall 6 of the first connecting pipe 9 and the wall thickness of a valve body wall 6 of the second connecting pipe 10 are increased to 13mm from 6.5mm of the original specification, and a layer of hard alloy material is spray-welded on a sealing surface 8 of the.
The utility model provides a sealed face spray welding carbide's high temperature resistant wear-resisting anticorrosive plug valve changes the retreat match bolt of original ordinary plug valve bottom into the plug bolt of valve body top, even the medium corrosivity that uses in chemical industry enterprise is strong, and the operating mode condition is under the condition of high temperature, taking the particulate matter more, after valve body and stopper wearing and tearing. And the leakage of the medium from the bottom of the valve body can be prevented, so that the environmental pollution is caused, and even operators are injured.
Additionally, the utility model discloses a sealed face spray welding carbide's high temperature resistant wear-resisting anticorrosive plug valve has increased the wall thickness of valve body wall to at the sealed face spray welding one deck carbide material of cock core, erosion-resistant corrosion resisting property has obtained very big improvement, and coefficient of friction is little, and durable more guarantees chemical industry enterprise's continuous operation requirement, has satisfied the requirement of economy, environment.
