Description
Technical field
The utility model relates to a kind of gate valve, specifically a kind of plough groove type fire-fighting signal gate valve belongs to fire protection pipeline
Machine component field.
Background technique
It is each used in from simplest shut-off valve to extremely complex robot control system(RCS) for the valve of fluid control systems
Kind valve, kind and specification are quite various, and valve can be used for controlling empty gas and water, steam, various corrosive medias, mud, oil
The flowing of the various types fluid such as product, liquid metal and radiating medium, gate valve are a kind of most common opening and closing valves, utilize flashboard
The medium in pipeline is connected or is truncated, it does not allow to use as shutting off, and avoids in use by the micro unlatching of flashboard, because of high speed
The erosion of the medium of flowing can accelerate the damage of sealing surface, in gate valve in use, rotation handwheel, passes through the screw thread of handwheel and valve rod
Advance and retreat, promoted or the flashboard that is connect with valve rod of decline, have the function that opening and closing, therefore gate valve can more intuitively be shown
Valve opening degree, to take in time corresponding measure in the aperture for remotely differentiating valve, opening and closing is reliable rapidly, therefore often
Applied to fire-fighting system.
The advantages of gate valve: fluid resistance is small, sealing surface by medium erosion it is small, opening and closing is relatively labor-saving, medium flow to it is unrestricted
System, body are simple；The shortcomings that gate valve: easily causing erosion and scratch between sealing surface, repairs relatively difficult.Existing gate valve is in valve
In the case that body, valve deck and each component are intact, only sealing surface slightly deforms or corrodes, and valve cannot use.
Utility model content
The technical problems to be solved in the utility model is against the above deficiency, to provide a kind of plough groove type fire-fighting signal gate valve,
The abrasion-resistance that can not only guarantee valve inner, also can protect adequately protect valve rod and valve plate, so that valve rod and valve plate exist
When opening and closing, friction is reduced to the greatest extent with contact surface.
In order to solve the above technical problems, the utility model uses following technical scheme:
A kind of plough groove type fire-fighting signal gate valve, including handwheel, valve rod, gland, valve deck, valve body and flashboard, the flashboard are set
It sets in valve body, the handwheel is mounted by means of bolts on the end of valve rod, and the gland is bolted on valve deck top
Portion, the valve deck are bolted on valve body top, and the valve rod passes through gland and valve deck is extend into valve body, the valve rod
It is equipped with sealing ring with gland junction, one end that the valve rod extend into valve body is equipped with nut, the nut and the fixed company of flashboard
It connects, it is screw rod that the valve rod, which passes through valve deck and extend into the intracorporal part of valve, and rest part is polished rod, between the valve deck and valve body
Rubber gasket equipped with annular.
Further, the flashboard is the structure that colloid is wrapped up in internal steel plate outer surface.
Further, the sealing ring is " O " type sealing ring, is provided with 3 altogether, close-packed arrays are sleeved on valve rod.
Further, even application non-toxic epoxy coating on the valve interior wall.
Further, the body base uses plain base seat design identical with water pipe.
The utility model relates to a kind of plough groove type fire-fighting signal gate valve, by the sealing ring added, reduce valve rod and
Friction between gland contact surface, so that gate valve is more lightly not easy leak, the encapsulated design of the entirety of flashboard in switch
Equally reduce the friction and erosion between gate valve and valve body and medium, the effective service life for extending flashboard, valve interior wall
Spray epoxy makes the abrasion-resistance of valve body higher, and the plain base design application of bottom in valve body so that be not easy to occur dirty
Object accumulation, so that the sealing of gate valve is relatively reliable.
The utility model is described in detail with reference to the accompanying drawings and examples.
