Abstract
The utility model discloses a self-sealing pressure stop valve which has a low wear rate. The self-sealing pressure stop valve comprises a valve body, wherein a channel is formed in the valve body; a valve seat is obliquely arranged in the middle of the channel in the valve body, a gate plate mutually matched with the valve seat is arranged in the valve body, and chromium alloy blocks are arranged on the valve seat and the gate plate respectively; the gate plate is connected with one end of a valve rod, the other end of the valve rod extends out of a nut on a valve deck to be connected with a handle, the nut and the valve deck are connected through a transversely fixed screw, and the valve deck is arranged in the valve body through a valve nut; and a soft stainless steel seal ring is arranged between the valve nut and the valve deck, an inclined surface arranged at the lower end of the soft stainless steel seal ring is mutually matched with an inclined surface at the upper end of the valve deck, and a hard alloy is arranged on the inclined surface at the upper end of the valve deck. The self-sealing pressure stop valve has the advantages as follows: the friction force is small in the operation process, the wear rate is low, the service life is long, the sealing effect is good, the maintenance is convenient, and the use requirement can be well met.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of pressure self-sealing gate valve.
Background technique
For the fluid in cutting out pipeline effectively, on pipeline, all can be provided with valve.Existing gate valve is to open in closing process frictional force larger, and wear rate is high, and working life is short, and the time has been grown and can cause sealing effect poor, and maintenance is inconvenient, can not meet well usage requirement.
Model utility content
Technical problem to be solved in the utility model is: the pressure self-sealing gate valve that a kind of wear rate is low is provided.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: pressure self-sealing gate valve, comprise: valve body, in described valve body, be provided with passage, at the tilted valve seat that is provided with of the middle part of described passage valve body, in described valve body, be provided with the flashboard cooperatively interacting with valve seat, on described valve seat and flashboard, be respectively arranged with evanohm piece, described flashboard is connected with one end of valve rod, the nut that the other end of valve rod stretches out on valve gap is connected with handle, between described valve gap and nut, be connected by horizontal set screw, described valve gap is arranged in valve body by valve mother, between described valve mother and valve gap, be provided with soft stainless steel sealing ring, the inclined-plane that the lower end of described soft stainless steel sealing ring is provided with inclined-plane and valve gap upper end cooperatively interacts, on the inclined-plane, upper end of described valve gap, be provided with cemented carbide.
The utility model has the advantages that: above-mentioned pressure self-sealing gate valve is arranged on pipeline, and in operating process, frictional force is little, and wear rate is low, long service life, good sealing effect, easy to maintenance, can meet well usage requirement.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model pressure self-sealing gate valve.
In figure: 1, valve body, 2, passage, 3, valve seat, 4, flashboard, 5, evanohm piece, 6, valve rod, 7, valve gap, 8, nut, 9, handle, 10, horizontal set screw, 11, valve mother, 12, soft stainless steel sealing ring, 13, cemented carbide.
Embodiment
Describe in detail particular content of the present utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, pressure self-sealing gate valve, comprise: valve body 1, in described valve body 1, be provided with passage 2, at the tilted valve seat 3 that is provided with of the middle part of described passage 2 valve body 1, in described valve body 1, be provided with the flashboard 4 cooperatively interacting with valve seat 3, on described valve seat 3 and flashboard 4, be respectively arranged with evanohm piece 5, described flashboard 4 is connected with one end of valve rod 6, the nut 8 that the other end of valve rod 6 stretches out on valve gap 7 is connected with handle 9, between described valve gap 7 and nut 8, be connected by horizontal set screw 10, described valve gap 7 is arranged in valve body 1 by valve mother 11, between described valve female 11 and valve gap 7, be provided with soft stainless steel sealing ring 12, the inclined-plane that the lower end of described soft stainless steel sealing ring 12 is provided with inclined-plane and valve gap 7 upper ends cooperatively interacts, on the inclined-plane, upper end of described valve gap 7, be provided with cemented carbide 13.
Above-mentioned pressure self-sealing gate valve is arranged on pipeline, by upwards poppet stem 6 of handle 9, thereby drive flashboard 4 to move upward until passage 2 is opened, when fluid interior through out-of-date at valve body 1, can produce thrust upwards to valve gap 7, thrust is larger, valve gap 7 is better in the effect lower seal performance of soft stainless steel sealing ring 12 and cemented carbide 13, can there is not fluid leakage, in the time of needs throttle down, by handle 9 extruding valve rod 6 downwards, thereby drive flashboard 4 to move downward until passage 2 is blocked, between flashboard 4 and valve seat 3, it is leaning structure, more easily insert and reduce friction, make between valve seat 3 and flashboard 4 coordinate tightr, sealing effect is strengthened, on valve seat 3 and flashboard 4, be all provided with evanohm piece 5, in the time of contact, wear rate is low, greatly extend working life.
