Abstract
The utility model belongs to a valve, in particular to a gate valve that prevents the valve bonnet and valve body from rusting, is convenient for replacing flashboard and maintenance, including a valve body, valve bonnet, valve rod, and flashboard. The valve bonnet forms a step combination of a small end, transition platform and big end, the round big end is disposed with internal thread connected with the external thread, the external hexagon small end is disposed with the internal thread on which the matched hob is disposed. The utility model yield the following beneficial effects that the big end of the valve bonnet adopts the internal thread to connect with the external thread of the valve body hole, a seal ring is disposed in the internal thread of the valve bonnet, the liquid medium passing through the valve body is stopped in the rubber gasket to make the matched thread not to contact the liquid medium which prevents the connection thread from rusting. If the flashboard needs replacing, only a small strength is needed to screw off the valve bonnet which is very convenient. Many gate valves have become waster because the valve is hard to dismantle while the new structure of the model has promoted the recycled rate of gate valves.
Description
Technical field
The utility model belongs to a kind of valve, relates in particular to a kind of valve gap and valve body of preventing and gets rusty conveniently replaced flashboard, the gate valve of being convenient to keep in repair.
Background technique
Middle mouthful of valve gap of gate valve is to adopt internal thread to be connected with valve body in the market.This kind Placement in use is in the flowing medium all the time, causes the screw thread of cooperation to get rusty easily.When valve rod and valve plate occur coming off and needs when changing flashboard, then must dismantle valve gap, because valve gap and valve body get rusty, six sides with valve gap twist into two parts also and can't take apart sometimes.
The model utility content
The purpose of this utility model is to provide a kind of gate valve, can prevent that a mouthful connecting thread can not get rusty in valve gap and the valve body, and it is very convenient to change flashboard.
For achieving the above object, by the following technical solutions: a kind of gate valve, comprise valve body, valve gap, valve rod, valve plate, it is characterized in that: described valve gap forms the cascade combination by microcephaly, transition bench and major part, enlarged rounded head is provided with internal thread and is connected with the outside thread of mouth in the valve body, outer hexagonal shaped microcephaly is provided with internal thread, and its top is provided with the pressure mother with its screw-thread fit.
The joining portion is provided with seal ring between described valve gap and the valve body.
Be provided with seal ring between described valve gap and the valve rod.
Described seal ring is an O shape cushion rubber.
Described pressure mother is outer six sides.
The beneficial effects of the utility model: the major part side of valve gap adopts internal thread to be connected with the outside thread of mouth in the valve body, the built-in seal ring of valve gap internal thread, the liquid medium that will flow through valve body stops in cushion rubber inside, makes the screw thread of cooperation not reach liquid medium, and avoids getting rusty in conjunction with screw thread.When needs are changed flashboard,, very convenient as long as just valve gap can be turned on very little strength.Since not quick detachable, cause a lot of gate valves to become waste product, and new structure can make the waste product rate of returning something for repairs improve.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Accompanying drawing is embodiment of the present utility model, describes in detail of the present utility model concrete below in conjunction with accompanying drawing
Mode of execution.
As shown in Figure 1, a kind of gate valve, comprise valve body 1, valve gap 2, valve rod 4, valve plate 5, described valve gap 2 forms the cascade combination by microcephaly 2-1, transition bench 2-2 and major part 2-3, enlarged rounded head is provided with internal thread and is connected with the outside thread of mouth in the valve body, outer hexagonal shaped microcephaly is provided with internal thread, and top is provided with the pressure mother 6 with outer six sides of its screw-thread fit.The joining portion is provided with seal ring 3 between described valve gap and the valve body.Be provided with seal ring 7 between described valve gap and the valve rod.Described seal ring is an O shape cushion rubber.By the original polytetrafluoroethylsealed sealed O RunddichtringO inner sealing that changes into.Valve gap is connected with the internal thread of valve body by in original outside thread and the valve body mouthful, become the outside thread Placement that adopts mouth in valve gap internal thread and the valve body, and the built-in O-ring seals of valve gap internal thread, the liquid medium that will flow through valve body stops in cushion rubber inside, make the screw thread of cooperation not reach liquid medium, and avoid getting rusty in conjunction with screw thread.As long as screw valve gap with very little strength, the leakage of liquid medium in use can not occur.When needs are changed flashboard,, very convenient as long as just valve gap can be turned on very little strength.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
Claims (5)
