Abstract
A kind of soft sealing gate valve, including handwheel, valve rod, flashboard, sealing member, valve gap and valve body, it is characterized in that: the position contacted with flashboard at valve body, it is provided with a slat gum sealing strip, this rubber weather strip embeds in the groove of valve body/flashboard, be provided with a stainless steel substrates at the middle part of rubber weather strip and protuberance, rubber weather strip is compressed by bolt and combines as a whole with valve body/flashboard by this stainless steel substrates.The present invention compared with prior art, has easily manufactured, and low cost of manufacture, good sealing effect, long service life overhaul convenient feature, is applicable not only to the opening and closing that pipeline is conventional, and is also applied for press and open holes.
Description
Technical field
The present invention relates to a kind of gate valve controlling fluid on-off, particularly relate to the soft sealing gate valve of a kind of good seal performance.
Background technology
At present, classic flat-plate gate valve is by valve body, hands is taken turns, valve rod, flashboard, sealing member, valve gap and valve seat etc. are constituted, it seals structure, mainly there are two kinds: one is hard sealing, for obtaining good sealing effectiveness, its grinding precision is high, manufacture difficulty is big, production cost is high, and in its opening-closing process, owing to valve seat contacts all the time with the sealing surface of flashboard, namely each valve is opened, close, the sealing surface of valve seat and flashboard is all in constantly phase mutual friction, the switch moment causing valve is bigger, thus accelerating the abrasion of valve seat and flashboard, cause that the service life of valve is shorter.Two is soft seal, owing to soft seal is entirely to be wrapped by flashboard with rubber, requires relative low to valve seat with the accuracy of manufacture of flashboard, sealing effectiveness is also better, but, due to rubber-coated flashboard open and close time, big with the frictional force of valve seat, thus causing that rubber quick abrasion, service life are short.
Summary of the invention
It is an object of the invention to provide a kind of soft sealing gate valve, to solve the problem that the existing flat gate valve accuracy of manufacture is high, production cost is high, service life is short.
The purpose of the present invention can be reached by techniques below measure, i.e. this soft sealing gate valve, including handwheel, valve rod, flashboard, sealing member, valve gap and valve body, it is characterized in that: the position contacted with flashboard at valve body, being provided with a slat gum sealing strip, this rubber weather strip embeds in the groove of valve body/flashboard.
Projection in the middle part of further described rubber weather strip, its lobe is respectively provided on two sides with and is cured as steel wire integrally with rubber weather strip, is provided with waterline outside steel wire.
Further be provided with a stainless steel substrates at the middle part of rubber weather strip and lobe, this stainless steel substrates is combined as a whole with rubber weather strip and valve body/flashboard by bolt.
In the middle part of described rubber weather strip, projection, both sides are provided with waterline；
The middle part projection 0.3-0.8mm of described rubber weather strip
Described valve rod one end and handwheel key connecting, the other end and flashboard thread connection.
According to the above-mentioned soft sealing gate valve assembled, during use, only need to rotating handwheel, flashboard just can being driven upper and lower, thus realizing the opening and closing of valve.
The present invention is compared with prior art, it is cured as steel wire integrally with rubber weather strip owing to being respectively provided on two sides with at the middle part of rubber weather strip and lobe, it is provided with waterline outside steel wire or is provided with a stainless steel substrates as slide plate at rubber weather strip protuberance, and it is provided with waterline in rubber weather strip both sides, when flashboard realizes downwards the cut out of valve, what first flashboard contacted is steel wire or stainless steel substrates, flatten so as to when contacting with both sides waterline when rubber weather strip is protruded part by flashboard, do not produce just to achieve reliable sealing when rubbing when between flashboard and valve body, not only good sealing effect, and long service life.Solve existing soft sealing gate valve to realize reliable sealing, it has to improve short problem in the production cost that brings of the accuracy of manufacture is significantly increased, friction between flashboard and valve body causes greatly service life.Additionally, the present invention also has easily manufactured, low cost of manufacture, good sealing effect, long service life, overhaul convenient feature, be applicable not only to the opening and closing that pipeline is conventional, and be also applied for press and open holes.

Detailed description of the invention
Referring to Fig. 1, Fig. 2, one soft sealing gate valve of the present invention, including hands 11, valve rod 5, flashboard 4, sealing member, valve gap 6 and valve body 1, it is characterized in that: the position contacted with flashboard 4 at valve body 1, be provided with a slat gum sealing strip 14, in the present embodiment, this rubber weather strip 14 embeds in the groove of valve body 1, projection in the middle part of described rubber weather strip 14, its lobe is respectively provided on two sides with and is cured as steel wire 15 integrally with rubber weather strip, is provided with waterline 16 outside steel wire 15；Certainly, do not repel in rubber weather strip and be not provided with being cured as steel wire 15 integrally with rubber weather strip, now should arrange a stainless steel substrates 13 at the middle part of rubber weather strip 14 and lobe, rubber weather strip 14 is compressed by bolt and is combined as a whole with valve body 1 by this stainless steel substrates 13.
Described valve gap 6 is connected by bolt 3 and valve body 1, valve rod 5 two ends are connected with handwheel 11 and flashboard 4 respectively, joint portion at flashboard 4, valve gap 6 and valve body 1, it is provided with rubber blanket 2, equipped with asbestos packing 9 between binder swivel nut 10 and threaded insert, it is provided with one group of O RunddichtringO 7 in the joint portion of valve rod 5 with valve gap 6, thus the dual-seal realized between valve gap and valve rod.
Described rubber blanket 2 is in shaped as frame.
Above example is only the technological thought that the present invention is described; protection scope of the present invention can not be limited with this; such as; rubber weather strip is embedded in valve body groove by the present embodiment; if rubber weather strip is embedded in the groove of flashboard by flashboard fluting; same can realization seals reliably, still falls within protection scope of the present invention.
