Deng on various gas medium pipeline.Combustion gas valve arrangement is single used at present, and can not prevent children from being operated, to solve
Above mentioned problem, spy provide a kind of new technical scheme.
The content of the invention
The purpose of this utility model is to provide a kind of natural gas valve, asked with solve to propose in above-mentioned background technology
Topic.
The utility model uses following technical scheme to achieve the above object：A kind of natural gas valve, including valve body, valve rod
And bonnet, the valve inner both ends offer connection screw thread, and spherical valve core is placed among valve inner, the valve rod plugs
Among above valve body, valve rod welds together with spherical valve core, and the driving lever and rotary shaft for connection, institute are provided with valve rod
Driving lever transverse weld is stated to be connected to valve stem top in the cylindrical both sides of valve rod, the rotary shaft by rotating shaft, be provided with rotary shaft
For the bearing pin and spring of connection, the bearing pin longitudinal measure is located in rotary shaft in the cylindrical both sides of rotary shaft, the spring housing,
The bonnet is sheathed in rotary shaft, and the elongated through hole for transmission and U-shaped hole, the elongated through hole longitudinal direction are provided with bonnet
The cylindrical both sides of bonnet are opened in, and bearing pin is equipped with elongated through hole, the U-shaped hole is laterally opened in the cylindrical bottom two of bonnet
Side.
Preferably, the internal diameter size in the U-shaped hole is identical with the outside dimension of driving lever.
Compared with prior art, the beneficial effects of the utility model are：The utility model valve rod is welded on spherical valve core
Together, the keying of valve element can be easily manipulated by valve rod；Driving lever transverse weld can easily be grasped in the cylindrical both sides of valve rod by driving lever
Control valve rod rotation；The bearing pin and spring for connection are provided with rotating shaft, can easily connect bonnet, and effectively prevents children because by mistake

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clear, complete elaboration.
As Figure 1-5, a kind of natural gas valve, including valve body 1, valve rod 2 and bonnet 3, the inside both ends of valve body 1 offer
Connection screw thread 4, the bosom of valve body 1 are placed with spherical valve core 5, and valve rod 2 is inserted among the top of valve body 1, valve rod 2 and globe valve
Core 5 welds together, and is provided with valve rod 2 cylindrical in valve rod 2 for the driving lever 6 and rotary shaft 7, the transverse weld of driving lever 6 of connection
Both sides, rotary shaft 7 are connected to the top of valve rod 2 by rotating shaft, and bearing pin 8 and spring 9 for connection, pin are provided with rotary shaft 7
The longitudinal measure of axle 8 is sheathed in rotary shaft 7 in 7 cylindrical both sides of rotary shaft, spring 9, and bonnet 3 is sheathed in rotary shaft 7, bonnet 3
On be provided with elongated through hole 10 and U-shaped hole 11 for transmission, the longitudinal direction of elongated through hole 10 is opened in 3 cylindrical both sides of bonnet, and long
Bearing pin 8 is equipped with type through hole 10, U-shaped hole 11 is laterally opened in 3 cylindrical two bottom sides of bonnet.
Specifically used mode：When progress valve is installed and used, main pipeline is threadingly attached to the connection of the one end of valve body 1
On screw thread 4, subtube is threadingly attached in the connection screw thread 4 of the other end of valve body 1；When carrying out valve opening, push valve
U-shaped hole 11 is snapped on the driving lever 6 on valve rod 2 by cap 3, and now the spring 9 in rotary shaft 7 is extruded contraction, subsequent rotary valve
Cap 3 drives driving lever 6 to rotate, and the rotating band ovable valve stem 2 of driving lever 6 rotates, and valve rod 2, which rotates, drives spherical valve core 5 to rotarily open valve；Valve
After door is opened, bonnet 3 is unclamped, now spring 9, which stretches to jack up bonnet 3, slides into the top of valve rod 2, and bearing pin 8 slips into elongated
The bottom of through hole 10, the position of bonnet 3 is effectively limited, when now rotating bonnet 3, rotary shaft 7 can only be driven to rotate, can not be to valve
The keying of door is manipulated.
Described above is the utility model preferred embodiment, for the ordinary skill in the art, according to this reality
With new teaching, in the case where not departing from principle of the present utility model and spirit, the change that is carried out to embodiment, repair
Change, replace and modification is still fallen within the scope of protection of the utility model.
