Description

A kind of gate valve

Technical field

The utility model is related to valve field, and in particular to a kind of gate valve.

Background technology

Gate valve is an opening and closing element flashboard, and the direction of motion of flashboard is perpendicular with flow direction, when gate valve is closed, sealing surface Seal by pressure medium, the sealing surface of flashboard is pressed to into the valve seat of opposite side to ensure the sealing of sealing surface, here it is from Sealing.Flashboard will be pressed to valve seat by most of gate valve by force using during forced seal, i.e. valve closing by external force, with Ensure the sealing of sealing surface, when opening and closing, valve element and sealing surface of seat are contacted all the time and phase mutual friction gate valve, thus Sealing surface easily weares and teares, and particularly when valve is in close closed mode, pressure reduction is very big before and after valve element, and sealing surface wear is just more Plus it is serious, but sealing surface wear easily causes leak or phenomenon of getting rusty, and keeps in repair relatively difficult, so as to shorten the use longevity of valve Life.

The content of the invention

The purpose of this utility model is the defect and deficiency for prior art, there is provided a kind of gate valve, its simple structure, Switch is light and handy, sealed reliable, be difficult to get rusty, long service life.

In order to solve the problems of background technology, the utility model is to employ the following technical solutions：A kind of gate valve, it Including valve body；Include valve seat, flashboard, valve rod, valve gap on described valve body；Described valve gap is arranged on valve body；Described valve Bar is connected through the valve gap with flashboard；Described top end of the valve body is provided with handwheel, and is connected with valve rod；Described valve body two ends It is provided with left connecting tube and right connecting tube；Described left connecting tube and right connecting tube is provided with valve seat near the inner of flashboard, It is arranged in valve flowing channel；Described flashboard includes sealing surface and outer wall；It is upper with runner sealing ring to be cased with described outer wall Inwall contradicts connection；The valve interior wall bottom of described valve rod vertical direction arranges fluted, the sealing surface with described flashboard Connection.

Further, the outer circumference surface of described left connecting tube and right connecting tube respectively with the lower end left and right side of valve body It is welded and fixed.

Further, the inner surface of described valve body is provided with anticorrosion inner liner.

Further, described ram seal face is using stainless steel and the ram seal face of hard alloy material；Described Flashboard outer wall adopts the sealing ring of quality of rubber materials.

Further, it is provided with filling gland between described handwheel and valve gap；Described valve rod is comply with through valve gap, is filled out Pressurising lid is connected with flashboard.

When the utility model is operated, the inner surface of valve body is provided with anticorrosion inner liner, and corrosive medium is directly and anti-corrosion Erosion inner liner contact, and not with other location contacts of valve body, this makes it possible to play good anticorrosion ability, ram seal Face is using stainless steel and the ram seal face of hard alloy material；Flashboard outer wall adopts the sealing ring of quality of rubber materials, it is to avoid sealing The harmful effects such as face is impaired, corrosion, safer, environmental protection.

The utility model beneficial effect：Its simple structure, switch light and handy, sealed reliable, be difficult to get rusty, long service life.

Description of the drawings

Accompanying drawing described herein is further understood to of the present utility model for providing, and constitutes of the application Point, but do not constitute to improper restriction of the present utility model, in the accompanying drawings：

Fig. 1 is the utility model structural representation；

Description of reference numerals：1- handwheels；2- valve bodies；3- valve rods；4- flashboards；The right connecting tubes of 5-；6- grooves；The left connections of 7- Pipe；8- valve gaps；9- valve seats；10- sealing rings；11- anticorrosion inner liners；12- filling glands.

Specific embodiment

Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, illustrative examples therein with And explanation is only used for explaining the utility model, but it is not intended as to restriction of the present utility model.

As shown in figure 1, this specific embodiment is employed the following technical solutions：A kind of gate valve, it includes valve body 2；Described Include valve seat 9, flashboard 4, valve rod 3, valve gap 8 on valve body 2；Described valve gap 8 is arranged on valve body 2；Described valve rod 3 passes through institute State valve gap 8 to be connected with flashboard 4；The described top of valve body 2 is provided with handwheel 1, and is connected with valve rod 3；The described two ends of valve body 2 set It is equipped with left connecting tube 7 and right connecting tube 5；Described left connecting tube 7 and right connecting tube 5 is provided with valve seat near the inner of flashboard 4 9, may be contained within the runner of valve body 2；It is cased with sealing ring 10 on the described outer wall of flashboard 4 to be connected with the upper inwall conflict of runner；Institute The inwall bottom of valve body 2 of the vertical direction of valve rod 3 stated arranges fluted 6, is tightly connected with described flashboard 4.
