Abstract
The utility model discloses a kind of cylinder valve structure, includes valve body, valve rod and core assembly, and the valve element of the core assembly and the inner thread of valve body connect, and valve rod is circumferentially fixed with valve element and is in axial sliding connection.Valve element of the present utility model is set as being connected with valve body screw thread, and the keying of valve element drives its rotation by valve rod, rotational valve core, valve element can the oscilaltion in valve body, so as to open and close the valve opening in valve body, the switch of cylinder valve is realized with this.Because valve element and valve body are threaded connections, the valve element state after closing is highly stable, good seal performance.Under opening, the sealing between valve rod and valve body need to only use conventional seal to achieve that good sealing, and during use, valve rod simply rotates, without moving axially, the abrasion of seal can be reduced, so as to effectively extend the service life of cylinder valve.It can be seen that the utility model cylinder valve has the advantages that rational in infrastructure, good seal performance, service life are long.
Description
Technical field
It the utility model is related to cylinder valve technical field.
Background technology
Often occur because security incident caused by liquefied petroleum gas leakage occurs on present society, and the crime of such accident
Stalwart chief culprit is cylinder valve.Such cylinder valve is usually present the features such as unreasonable structure, poor sealing performance, short service life, causes to hold
Easily there is liquefied petroleum gas leakage problem.Therefore, it is necessary to research and develop a kind of rational in infrastructure, good seal performance, service life is grown
Cylinder valve.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of service life length of good seal performance rational in infrastructure
Cylinder valve structure.
Technical scheme used by solve above-mentioned technical problem：A kind of cylinder valve structure, includes valve body, is axially fixed in
The valve rod that rotates in valve body and in valve body blocking the core assembly of valve opening, it is characterised in that：The core assembly
The inner thread of valve element and valve body connects, and valve rod is circumferentially fixed with valve element and is in axial sliding connection.
On the basis of the above, the end of the connection valve element of the valve rod forms square inserting column, and valve element forms accommodating inserting column and inserted
The slot connect.
On the basis of the above, the bottom of the valve element is provided with valve pad, and sealing ring is provided between valve rod and valve body.
Using beneficial effect caused by the utility model：Valve element of the present utility model is set as being connected with valve body screw thread, valve
The keying of core drives its rotation by valve rod, rotational valve core, valve element can the oscilaltion in valve body, so as to open and close valve body
Interior valve opening, the switch of cylinder valve is realized with this.Because valve element and valve body are threaded connections, the valve element state after closing is very steady
Fixed, good seal performance.Under opening, the sealing between valve rod and valve body need to only use conventional seal to achieve that very
Good sealing, and during use, valve rod simply rotates, and without moving axially, can reduce the abrasion of seal, from
And effectively extend the service life of cylinder valve.It can be seen that the utility model cylinder valve has rational in infrastructure, good seal performance, service life length
The advantages that.

Embodiment
As shown in figure 1, a kind of cylinder valve, includes valve body 1, is axially fixed in the interior valve rod 2 rotated of valve body 1 and in valve body
Blocking the core assembly of valve opening 3 in 1.In the utility model, the valve element 4 of the core assembly and the inwall spiral shell of valve body 1
Line connects, and valve rod 2 is circumferentially fixed with valve element 4 and is in axial sliding connection.When rotation valve rod 2, the circumferentially fixed valve element with valve rod 2
4 will follow rotation, now with valve rod 2 in axial sliding valve element 4 will oscilaltion, so as to beat the valve opening 3 of valve body 1
On or off is closed.
In the present embodiment, the end of the connection valve element 4 of the valve rod 2 forms square inserting column 21, and valve element 4 forms accommodating insert
The slot 41 of the grafting of post 21.Certainly, the connection of valve rod 2 and valve element 4 can also use the circumferentially fixed company of routine of other on-circular cross-sections
Connect mode.Specifically, valve rod 2 can form single inserting column 21, as shown in Figure 2；Also double joint inserting column 21 can be formed, as shown in Figure 3.
For the valve rod 2 of double joint inserting column, the part cell wall between two inserting columns 21 of the slot 41 of valve element 4 can snatch a moment as broadening, such as Fig. 4
It is shown, the dosage of the material of processing valve element 4 can be so reduced, reduces production cost.
Generally, the bottom of valve element 4 is provided with valve pad 5, and sealing ring 6 is provided between valve rod 2 and valve body 1, and sealing ring 6 can be set
Put multiple tracks.Valve pad is for preferably blocking valve opening 3, and sealing ring 6 can prevent the gas leak in bottle.
Claims (3)
1. a kind of cylinder valve structure, include valve body, be axially fixed in valve body in the valve rod that rotates and in valve body blocking
The core assembly of valve opening, it is characterised in that：The valve element of the core assembly and the inner thread of valve body connect, valve rod and valve element week
To fixation and it is in axial sliding connection.
2. cylinder valve structure according to claim 1, it is characterised in that：The end of the connection valve element of the valve rod forms square
Inserting column, valve element form the slot of accommodating inserting column grafting.
3. cylinder valve structure according to claim 1 or 2, it is characterised in that：The bottom of the valve element is provided with valve pad, valve rod
Sealing ring is installed between valve body.
