Description
Technical field
This utility model relates to ball valve technical field, is specifically related to a kind of anti-blow structure of forging steel ball valve.
Background technology
Forged steel ball valve structure is simple, and good seal performance is widely used in the industry such as oil, natural gas.But due to it
Bore specification is less, and especially for 1 inch and following small ball, owing to space limits, when ball valve assembles, its valve rod leads to
Chang Wufa loads at valve lumen.Forging steel ball valve on the market, it is typically to open a hole bottom valve, makes the valve rod can be from
Penetrate bottom valve, then with plug screw, bottom port is blocked, but this can increase the leak point of valve.
Utility model content
The purpose of this utility model is to provide a kind of anti-blow structure of forging steel ball valve, and this structure can facilitate the dress of ball valve
Join.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of anti-blow structure of forging steel ball valve, including valve body, valve rod, spheroid, stop collar, above-mentioned valve rod passes above-mentioned valve
Body, above-mentioned valve body includes that the cylinder corresponding with valve rod, above-mentioned cylinder are provided with spacing ring, and above-mentioned stop collar is sheathed on above-mentioned valve rod,
Above-mentioned valve rod is connected by bearing pin is fixing with above-mentioned stop collar, and above-mentioned stop collar is positioned at the lower section of above-mentioned spacing ring.
Preferably, above-mentioned valve stem sleeve is provided with the first thrust pad, and above-mentioned first thrust pad is positioned at above-mentioned spacing ring and stop collar
Between.
Preferably, above-mentioned valve stem sleeve is provided with gland, and above-mentioned gland is bolted on the top of valve gap, above-mentioned spacing ring
Upper surface, valve rod, valve body and gland lower surface between be formed sealing space, above-mentioned sealing space is filled with airtight and watertight padding,
Above-mentioned valve stem sleeve is provided with the second thrust pad, and above-mentioned second thrust pad is between above-mentioned airtight and watertight padding and gland.
Operation principle of the present utility model is: valve rod directly stretches into from body top, then by the first thrust pad, bearing pin and
Stop collar installs to valve rod from valve body lumen, is finally sequentially loaded into ball seal filler, the second thrust pad and gland to correct
Position；Achieve effective quick assembling of ball valve.
The beneficial effects of the utility model are: valve rod can be made easily to load from top, can meet again the anti-blow of valve rod
Requirement；Decrease the leakage point of valve, make sealing relatively reliable.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is further described.Hereinafter implement
Example is only used for clearly illustrating the technical solution of the utility model, and can not limit protection model of the present utility model with this
Enclose.
The technical scheme that this utility model is embodied as is:
As it is shown in figure 1, a kind of anti-blow structure of forging steel ball valve, including valve body 3, valve rod 1, spheroid 4, stop collar 5, above-mentioned valve
Bar 1 is through above-mentioned valve body 3, and above-mentioned valve body 3 includes that the cylinder corresponding with valve rod 1, above-mentioned cylinder are provided with spacing ring 31, above-mentioned spacing
Set 5 is sheathed on above-mentioned valve rod 1, and above-mentioned valve rod 1 is connected by bearing pin 7 is fixing with above-mentioned stop collar 5, and above-mentioned stop collar 5 is positioned at
State the lower section of spacing ring 31.
Above-mentioned valve rod 1 is arranged with the first thrust pad 61, and above-mentioned first thrust pad 61 is positioned at above-mentioned spacing ring 31 and stop collar 5
Between.
Above-mentioned valve rod 1 is arranged with gland 2, and above-mentioned gland 2 is bolted on the top of valve gap, above-mentioned spacing ring 31
Being formed with sealing space between upper surface, valve rod 1, valve body 3 and gland 2 lower surface, above-mentioned sealing space is filled with airtight and watertight padding
8, above-mentioned valve rod 1 is arranged with the second thrust pad 62, and above-mentioned second thrust pad 62 is between above-mentioned airtight and watertight padding 8 and gland 2.
Operation principle of the present utility model is: valve rod 1 directly stretches into from valve body 3 top, then by the first thrust pad 61, pin
Axle 7 and stop collar 5 install to valve rod 1 from valve body 3 lumen, are finally sequentially loaded into spheroid 4 airtight and watertight padding the 8, second thrust pad 62 and
Gland 2 is to correct position；Achieve effective quick assembling of ball valve.
The beneficial effects of the utility model are: valve rod 1 can be made easily to load from top, can meet again the anti-of valve rod 1 and blow
Go out requirement；Decrease the leakage point of valve, make sealing relatively reliable.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model know-why, it is also possible to make some improvements and modifications, these change
Enter and retouch and also should be regarded as protection domain of the present utility model.
