Description
Technical Field
The utility model belongs to the valve field, especially, gate valve with rust-resistant function.
Background
The valve is widely applied to the fields of petroleum, petrochemical oil transportation and gas transportation pipelines, and aims to ensure the durability of the valve. Cast iron is generally used as a main material of the valve, and once the cast iron valve is corroded, problems of untight closing, leakage and the like can be caused, so that the cast iron valve has great potential safety hazard, needs to be maintained and replaced, and is high in cost.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's weak point, provide a design science, simple structure, be convenient for operation, raise the efficient gate valve that has rust-resistant function.
The utility model provides a its technical problem take following technical scheme to realize:
a gate valve with rust-resistant function which characterized in that: including valve body, flashboard, valve rod, disk seat and glued membrane, valve body middle part system has the horizontal runner that link up, installs the flashboard in the runner middle part, and the system of flashboard lower part has the horizontal runner through-hole the same with the runner diameter, flashboard upper end middle part coaxial coupling valve rod, its characterized in that: the valve seats are coaxially and limitedly arranged in the runners at the two transverse ends of the flashboard, the inner wall of the runner in the valve body is uniformly coated with a layer of glue film, and the glue film extends to the runner of the valve body to form an extended glue ring.
And an annular sealing strip is arranged in the middle of the end face of the valve seat on one side facing the flashboard, the sealing strip protrudes out of the end face of the valve seat, and the sealing strip is made of rubber.
Moreover, the flashboard is made of nylon materials.
The lower end of the middle part of the valve body is provided with a flashboard telescopic cavity, and the lower part of the flashboard is inserted into the flashboard telescopic cavity when the flashboard presses down to close the flow passage; the lower part of the gate plate telescopic cavity is made into a funnel-shaped structure, and the bottom of the center of the funnel is provided with a sewage discharge hole.
And the upper part of the valve rod coaxially penetrates out of the valve body, and a hand wheel assembly is arranged on the upper part of the valve rod above the valve body and can drive the valve rod to move up and down, so that the valve rod drives the flashboard to move up and down in the valve body.
The utility model has the advantages that:
the utility model discloses a rubber coating technology of brand-new introduction carries out the rubber coating to the runner inner wall of valve body and handles, and the framework is simple reliable, has kept the firm of cast iron valve body promptly and has reliably prevented effectively again and separates valve body and liquid contact, and rust-resistant effectual.

Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments, which are illustrative, not restrictive, and the scope of the invention should not be limited thereto.
The utility model provides a gate valve with rust-resistant function, including valve body 6, flashboard 3, valve rod 2, disk seat 5 and glued membrane 7, 6 middle part systems of valve body have the runner that transversely link up, install flashboard 3 in the runner middle part, flashboard lower part system has the transverse flow channel through-hole the same with the runner diameter, flashboard upper end middle part coaxial coupling valve rod 2, the valve body is worn out to the valve rod upper portion is coaxial, and install hand wheel assembly 1 on the valve rod upper portion of valve body top, hand wheel assembly can drive the valve rod and reciprocate, make the valve rod drive the flashboard move up and down in the valve body.
The flashboard is made of nylon materials, the flashboard is lighter in weight, smooth in sliding and not prone to rusting.
And valve seats 5 are coaxially and limitedly arranged in the flow passages at the two transverse ends of the flashboard. In order to guarantee the leakproofness of contact surface, there is an annular sealing strip 4 at the disk seat terminal surface mid-mounting towards flashboard one side, and the outstanding disk seat terminal surface of sealing strip, the sealing strip receives the extrusion promotion leakproofness when the flashboard seals the runner, prevents that liquid stream from letting the valve body cause the corrosion, and the sealing strip adopts rubber material.
The inner wall of the flow passage in the valve body is uniformly coated with a layer of glue film 7, and the glue film extends to the flow passage of the valve body to form an outward-extended glue ring 8.
The lower end of the middle part of the valve body is provided with a flashboard telescopic cavity, and the lower part of the flashboard is inserted into the flashboard telescopic cavity when the flashboard presses down to close the flow passage; the lower part of the gate plate telescopic cavity is made into a funnel-shaped structure, and the bottom of the center of the funnel is provided with a sewage discharge hole 9, so that impurities carried by the gate plate into the cavity can be discharged in time.
Although the embodiments of the present invention and the accompanying drawings are disclosed for illustrative purposes, those skilled in the art will appreciate that: various substitutions, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims, and therefore, the scope of the present invention is not limited to the disclosure of the embodiments and the accompanying drawings.
