Abstract
The utility model relates to a flat gate valve. The flat gate valve comprises a valve body, a drive device, a valve seat, a valve rod, a valve plate, a rubber cushion and a seal ring. The valve rod is connected with the drive device, the valve rod is connected with the valve plate used for sealing the valve seat, the bottom of the valve plate is in an arc shape, the sealing face of the valve plate is provided with the rubber cushion, the valve seat is provided with the seal ring, and the rubber cushion and the seal ring are sealed in a matched mode. According to the flat gate valve, the high speed fluid can stably flow, the sealing and corrosion resistance performance is good, the using period of the valve seat and the valve plate is guaranteed, and production efficiency is improved.
Description
Technical field
The utility model relates to a kind of start-stop device for gathering line, relates in particular to a kind of plate valve.
Background technique
Plate valve is that a kind of closure member is the slide-valve of parallel gate plate, it is a kind of start-stop device being widely used on gathering line, it can control fluid flow size and cut-off easily, in oil extraction in oil field and rock gas, water and heating process, well head is all connected with pipeline by gate, by gate, controls uninterrupted and open and close.Its closure member can be Single disc or therebetween with the double-flashboard of spreading mechanism, flashboard is to be controlled by the pressure medium that acts on float flashboard or floating valve seat to the impacting force of valve seat.If Double Disc Flat Gate Valves, the spreading mechanism between two flashboards can supplement this impacting force.And existing gate is because of the Long Term Contact of sealing surface of seat and valve plate, make valve seat and valve plate corrosion, cause gate valve to be not closed completely, leak liquid, has shortened the life cycle of valve seat and flashboard, has reduced manufacturing efficiency, has affected normal operation and production.
Model utility content
In order to overcome the defect of above-mentioned prior art, the utility model provides a kind of plate valve, and this plate valve not only can guarantee high-velocity fluid smooth flow, and sealing and antiseptic property good, guaranteed the life cycle of valve seat and flashboard to have improved manufacturing efficiency.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of plate valve, comprise valve body and drive unit, it is characterized in that: also comprise valve seat, valve rod, valve plate, rubber pad and seal ring, described valve rod is connected with drive unit, described valve rod is connected with the valve plate for seal valve seat, and the bottom of described valve plate is arc, and the sealing surface of described valve plate is provided with rubber pad, described valve seat is provided with seal ring, described rubber pad and seal ring fitted seal.
Described seal ring is O RunddichtringO or V-shaped seal ring.
The utlity model has following advantage:
In the utility model, the bottom of valve plate is arc, the sealing surface of described valve plate is provided with rubber pad, described valve seat is provided with seal ring, described rubber pad and seal ring fitted seal, the bottom of dull and stereotyped valve plate adopts arcuate structure, when liquid at high speed flows, valve plate pressure at both sides balance, has guaranteed the stability of working when valve body high-speed liquid flows; The sealing surface of valve plate is provided with rubber pad, and described valve seat is provided with seal ring, described rubber pad and seal ring fitted seal, due to the strong seal action of rubber pad, guaranteed the sealing effect of valve body, also just improved antiseptic property simultaneously, the life cycle that has guaranteed valve seat and valve plate, has improved efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Mark in figure: 1 valve body, 2 drive units, 3 valve seats, 4 valve rods, 5 valve plates, 6 rubber pads, 7 seal rings.
Embodiment
Embodiment 1
As shown in Figure 1, a kind of plate valve, comprise valve body 1 and drive unit 2, also comprise valve seat 3, valve rod 4, valve plate 5, rubber pad 6 and seal ring 7, described valve rod 4 is connected with drive unit 2, described valve rod 4 is connected with the valve plate 5 for seal valve seat, drive unit 2 actuate valve stem 4 seal 5 pairs of valve seats 3 of valve plate, and the bottom of described valve plate 5 is arc, when liquid at high speed flows, valve plate pressure at both sides balance, has guaranteed the stability of working when valve body high-speed liquid flows; The sealing surface of described valve plate 5 is provided with rubber pad 6, and described valve seat 3 is provided with seal ring 7, described rubber pad 6 and seal ring 7 fitted seal, and seal ring 7 is O RunddichtringO or V-shaped seal ring.
Due to the strong seal action of rubber pad, guaranteed the sealing effect of valve body, also just improved antiseptic property simultaneously, guaranteed the life cycle of valve seat and valve plate, improved efficiency.
