Abstract
The utility model discloses a flange type flat plate gate valve which is suitable for two-phrase flow medium containing solid granules. The utility model mainly comprises a valve body, a valve cover, a gate plate, and a valve rod. The utility model is characterized in that symmetrical valve seats are arranged at both sides of the gate plate; the valve seats are arranged in the diameter of the valve body; a spring is arranged in the gap between the valve seats and the valve body and is used for supporting the valve seats and sealing the gate plate, namely, a sliding valve seat; resin and metal double layer sealing rings are arranged in the valve seats. Hence, the product has the characteristics of good sealing effect, long service life, low temperature resistance, strong anti-sulphuric acid performance, convenient operation, etc.
Description
The utility model belongs to the gate valve that industrial pipeline is used.
Domestic at present, normally usedly be applicable to gate valve on the pipelines such as water, oil, rock gas, the deficiency that ubiquity is following:
1, anticorrosive, wear-resistant or resistance to low temperature is poor, working life is short;
2, the inlet/outlet sealing effect is bad, leakiness often occurs;
3, volume or weight is big, uses inconvenient.
The purpose of this novel invention provide a kind of above-mentioned deficiency that can overcome, and it is little to have open and close moment, and long service life can be low temperature resistant and have the sulfuric-resisting performance strong, is applicable to the plate valve on the pipeline of the two-phase flow medium that contains solid particle.
For realizing above-mentioned goal of the invention, this is novel takes following technical measures: this novel it comprise have in valve body, handwheel, valve gap, the valve body chamber threaded valve rod and with the flashboard of its socket; It is characterized in that: described two ends of valve body is provided with the latus rectum identical with pipeline, in its latus rectum, be provided with the metal seat valve of the slip that is symmetrical in flashboard, and in the valve body latus rectum and the gap between the valve seat is provided with spring and by its supporting valve seat, makes it the flashboard metallic seal; Described valve seat is provided with Baltimore groove, is provided with the sealing of resin and metal bi seal ring in its groove, like this valve body and flashboard is formed double-layer seal.
This novel its feature also is: the Stem Mut of described valve rod upper end socket adopts aluminum bronze to manufacture; Described flashboard is provided with cobalt network tungsten coating outward.
This novel compared with prior art beneficial effect is as follows:
1, this new structure is reasonable in design, and manufacture technology is simple, and it adopts aluminum bronze to make Stem Mut, can reduce friction, and it is little to make it gate valve open and close moment; Its flashboard adopts stainless steel+cemented carbide (being coated with cobalt network tungsten), makes its hardness height, and is anticorrosive, wear-resistant; Its valve seat is provided with resin and metal bi seal ring (promptly valve body and flashboard being played the effect of double-layer seal), and its valve seat is supported it by spring, forms the valve seat that slides, and when body cavity pressure raise, valve seat can be made a concession automatically and release too high pressure; Valve body have with in the identical latus rectum of pipeline, be convenient to clean pipeline.Therefore this product has anticorrosively, wear-resistant, and anti-low, high-temperature behavior reaches characteristics such as long service life by force, is applicable to the two-phase flow medium that contains solid particle.
2, this new function is strong, and is easy to use, and promptly driving mode can be manual or electronic.
3, basis is novel need not dismantle shutdown owing to inlet/outlet all seals, disconnects fully with passage during maintenance, and operation is very easy.
Description of drawings:
Fig. 1 is the ssembly drawing of this novel overall structure;
Fig. 2 is the valve seat of body cavity of Fig. 1 and the structure amplification view of flashboard.
Describe in further detail below in conjunction with the mode of execution of above-mentioned accompanying drawing this programme:
Referring to Fig. 1～2, this novel it comprise threaded valve rod 4 is arranged in valve body 1, handwheel 2, valve gap 3, valve body 1 chamber, with the Stem Mut 5 of valve rod 4 top sockets and with the flashboard 6 of valve rod 4 lower end sockets; Described flashboard 6, valve rod 4, valve body 1, valve seat 7, employing special processing technology.Its flashboard 6 adopts stainless steel+cemented carbide (being coated with one deck cobalt network tungsten); Socket Stem Mut 5 adopts aluminum bronze to manufacture outside its valve rod 4 tops; Its valve body 1 and valve gap 3 are smart casting, the two ends of valve body 1 are advanced, the outlet port is provided with identical latus rectum with pipeline, and pipeline is connected with valve body 1 flange, flashboard 6 bottoms also are provided with the through hole 10 that communicates with it, be provided with the valve seat 7 that is symmetrical in flashboard 6 both sides in valve body 1 latus rectum and place in the latus rectum, gap between valve body 1 and valve seat 7 is provided with spring 8 by its supporting valve seat 7, form the valve seat 7 that slides, make it flashboard 6 metals, be provided with Baltimore groove in the above-mentioned valve seat 7, in its groove, be provided with resin and metal bi seal ring 9,9 ', valve body and flashboard 6 are played the effect of double-layer seal.
During use, because Stem Mut 5 and handwheel 2 are fixed, handwheel 2 rotating valve rod nuts 5 change together, and drive valve rod 4 risings or decline, and when driving valve, flashboard 6 declines make the through hole 10 on it communicate with pipeline drift diameter; Otherwise gate valve 6 rises and latus rectum breaks away from, and makes valve close valve.
