Description
Technical field
The invention belongs to water pipe junction valve fields, and in particular to a kind of dark valve of built-in stainless steel card pressure.
Background technique
Valve (Valve) is the mechanical device of flow, flow direction, pressure, temperature of fluid media (medium) of control flowing etc., valve
Component basic in pipe-line system, valve pipe fitting technically with pump, begged for often as an individual classification
By valve available manual or handwheel, handle or pedal operation can also change the pressure of fluid media (medium), temperature by controlling
Degree and changes in flow rate, valve can carry out continuous or duplicate operation to these variations, such as in hot-water heating system or steam boiler
The safety valve of installation, in more complicated control system according to external input (adjust and flow through the continually changing set-point of pipeline)
It needs using autocontrol valve, autocontrol valve is not required to manual operation according to its input and setting, accurately controls valve
The requirements of fluid media (medium), valve according to material be also divided into cast iron valve, cast steel valve, stainless valve, chrome-molybdenum steel valve,
Chrominm-molybdenum-vanadium steel valve, dual phase steel valve, Plastic valve and the nonstandard valves material such as customized.
Connecting valve kind, specification, model, function, connection type in national feedwater piping etc. are various, but pass through
The connection valve of squash type connection is more rare at present, and common some connecting valves being connected through a screw thread make in junction
The situation of some leaks can occur after having been grown with the time, using effect is not ideal enough, and is easily damaged.
Summary of the invention
The object of the invention is that solve the above-mentioned problems and to provide a kind of structure simple, design in reasonable one kind
Concealed stainless steel card presses dark valve.
The present invention through the following technical solutions to achieve the above objectives:
A kind of dark valve of built-in stainless steel card pressure, including valve body and the bonnet, being located on valve body, the valve body and upper valve
It is flexibly connected between lid by rotary shaft, and the outer surface of rotary shaft is connected with cross rotation handle close to the position of upper end
Hand, the valve that can be drivingly connected in valve by rotary cross rotating handles are moved, and the water flow in Lai Shixian connection valve is logical
Disconnected, the upper end of the rotary shaft is movably installed with fastening nut, and the valve body two sides are welded with pipe close to the position of lower end
Road, and reinforcing rib is provided between valve body and pipeline, reinforcing rib can make the bonding strength between the water pipe and valve body of welding
Increase, the inner wall that clamping protrusion is provided on the pipeline, and is clamped protrusion is equipped with mating groove, the mating groove agree with have it is close
Seal, and sealing ring upper end is welded with interior loss prevention protrusion, can be attached in interior loss prevention protrusion after being clamped raised deformation, can also be with
Realization further prevents being clamped the excessive effect of raised deformation, and the effect of sealing can also be played when clamping protrusion occurs damaged
Fruit.
As a further optimization solution of the present invention, valve, the lower end of the rotary shaft and valve are equipped in the valve body
It is fixedly connected, valve is driven valve to be rotated or moved by the control of rotary shaft by controlling the rotation of rotary shaft, is realized

Deformation gap is equipped between the width of sealing ring, the interior loss prevention protrusion and clamping protrusion, deformation gap is clamping protrusion
Deformation range may result in its impaired, interior loss prevention at this time after being clamped raised excessive deformation once being more than the range in this gap
It is raised then play continue sealing effect, it is ensured that junction do not have water flow leakage.
As a further optimization solution of the present invention, the interior loss prevention protrusion and the material of sealing ring are stainless steel, are protected
Its rigidity is demonstrate,proved, entire valve all uses 304 stainless steels, and water-stagnating effect is good, and pressure-bearing can reach 2.5 megapascal, outside
See generous improve grade.
The beneficial effects of the present invention are:
1) present invention is provided with clamping protrusion in water pipe junction, the water pipe in connection valve directly can be sticked into outside water
Guan Zhong is fitted closely with external water pipe volume inner wall by the deformation of clamping protrusion, can guarantee the leakproofness of junction, Neng Goufang
Only there is the case where leak in junction, and reduces the production cost of connection valve, shortens construction period,；
2) present invention in the interior loss prevention protrusion of clamping lobed interior setting by that can make connection valve be suitable for certain model
Water pipe connection in enclosing, can prevent clamping protrusion from the feelings of leak occurring when its surface being caused to occur damaged because of excessive deformation
Condition, and can be blocked the space for being clamped lobed interior by sealing ring, water flow can be made not shunt, so that connection valve
The effect of conveying water is unaffected；
3) the configuration of the present invention is simple, stability is high, and design rationally, is easy to implement.
