Description
Technical field
The utility model belongs to control valve technical field, refers in particular to a kind of high-intensity sealing main valve lid.
Background technique
Main valve is component important in fluid transmission, and valve deck is an important composition component on main valve, that is, is connected to
The circulation of fluid in valve rod control valve, also functions to sealing function, and in some cases, main valve needs to bear the stream of larger pressure
Body impact, therefore, the valve deck of main valve needs it with certain intensity, prevents high-pressure fluid from damaging to valve.Moreover, existing
After prolonged use, the seam crossing of valve deck and valve is easy to appear infiltration phenomenon to some valves, is easy to generate corrosion to valve,
The twisting force that valve is rotated in long-time by valve rod simultaneously, makes to generate gap between valve deck and valve, leads to valve invalidation,
Moreover, the valve rod of valve is easy to continue stress after closing, lead to the impaired failure in valve rod junction, reduce valve uses the longevity
Life.
Summary of the invention
In view of the deficienciess of the prior art, that the purpose of the utility model is to provide a kind of intensity is high, good airproof performance and right
Valve rod is capable of the high-intensity sealing main valve lid of effective position.
Purpose of the utility model is realized as follows: a kind of high-intensity sealing main valve lid, including main body and fixing seat, institute
The quadrangle that fixing seat is located at body inner surface is stated, screw hole, the fixed seating face are provided among the fixing seat
It is provided with rubber pad, knob and reinforced pipe are provided on the body inner surface, casing, casing are provided on the reinforced pipe
Outer diameter, which is less than, reinforces pipe outside diameter, and the reinforced pipe two sides are provided with two opposite through-holes, are provided with around the through-hole
Reinforcing rib, is provided with locating slot on the knob, and the body inner surface is provided with spring leaf, the spring leaf and fixed
Position slot cooperation positioning, the body edge are provided with sealant along boss is provided on the inside of boss, sealant and boss respectively with
Fixing seat connection.
The utility model advanced optimizes are as follows: the sealant is rubber layer or layer of silica gel.
The utility model advanced optimizes are as follows: the body surfaces are provided with zinc coat.
Compared with the prior art, the utility model has prominent and beneficial technical effects that: the casing of the utility model is inserted into valve
In the main body of door, the reinforced pipe can increase the use intensity of casing, meanwhile, it is provided with through-hole on reinforced pipe, prevents from adding
Strong pipe generates obstruction to the fluid flow rate in valve, meanwhile, rubber pad is provided in each fixing seat of main body, it is possible to increase valve deck
The tightness degree connected between valve is prevented for a long time using generation infiltration phenomenon, while being provided between each fixing seat
Sealant, sealant can further prevent valve deck and valve junction generates gap, while be provided with boss outside sealant, both may be used
To increase the use intensity of valve deck entirety, the sealing effect of device can also be increased, the knob is for installing valve rod, knob
On be provided with locating slot, locating slot is matched with the spring leaf in main body, can be positioned to knob, prevents from using when switching knob
Power is excessive, damages to valve.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；

Screw hole is provided among reservation 2, screw hole is used to connect with valve, and 2 surface of fixing seat is provided with rubber pad 11, can increase
The tightness degree connected between big valve deck and valve prevents for a long time using generation infiltration phenomenon, 1 edge of the main body setting
There is boss 3, the step can both increase the use intensity of valve deck entirety, can also increase the sealing effect of device, in boss 3
Side is provided with sealant 4, and sealant 4 and boss 3 are connect with fixing seat 2 respectively, and sealant 4 can further prevent valve deck and valve
Junction generates gap.
It is provided with knob 9 and reinforced pipe 5 on 1 inner surface of main body, casing 7 is provided on the reinforced pipe 5, it is described
Casing 7 be inserted into valve portion, be provided with the fixed ring matched with casing 7 in valve, casing 7 and fixed ring cooperation limit,
Stability after increasing valve deck installation, 7 outer diameter of inner sleeve are less than 5 outer diameter of reinforced pipe, and the step of formation can limit main valve lid
Position, 5 two sides of reinforced pipe are provided with two opposite through-holes 8, reinforcing rib 6 are provided with around the through-hole 8, using this
Structure, reinforced pipe 5 can increase the use intensity of casing 7, meanwhile, through-hole 8 is provided on reinforced pipe 5, through-hole 8 can prevent from reinforcing
Pipe 5 has an impact the fluid flow rate in valve.
The utility model is further arranged to, and the knob 9 is used to install valve rod, and it is fixed to be provided on the knob 9
