Abstract
The utility model discloses a kind of core assembly, includes in, to block the blocking type core assembly of valve opening, the bottom of the closure valve opening of the valve element of core assembly is fixed with valve pad in valve body, it is characterised in that：The valve pad is inlaid in the cavity of valve element bottom, and bias grafting at least one is set as between the valve pad and cavity.Because valve pad of the present utility model is inlaid in the cavity of valve element bottom, its installation is very convenient, and is to use eccentric grafting between valve pad and valve element cavity, during valve core rotation, valve pad follows valve element to rotate together, prevents valve pad from being slided with valve element, valve pad is hardly damaged, service life length.
Description
Technical field
It the utility model is related to cylinder valve technical field, in particular to for opening and closing the core assembly of cylinder valve.
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.For example some cylinder valves open and close valve opening using blocking type core assembly, by rotating valve
Bar drives valve element to be lifted in valve body, to open or close the valve opening in valve body.The bottom of this valve element is typically all installed by valve
Pad, for sealing valve opening.But this valve pad is mounted so as to not reasonable, processing and installation is more inconvenient, is easily damaged.Therefore, have
Necessity is easily installed and durable core assembly for cylinder valve research and development are a kind of.
Utility model content
The technical problems to be solved in the utility model provides a kind of be easily installed and durable core assembly for cylinder valve.
Technical scheme used by solve above-mentioned technical problem：A kind of core assembly, include in valve body sealing
The blocking type core assembly of stifled valve opening, the bottom of the closure valve opening of the valve element of core assembly are fixed with valve pad, it is characterised in that：Institute
State valve pad to be inlaid in the cavity of valve element bottom, bias grafting at least one is set as between the valve pad and cavity.
On the basis of the above, the inserting column being mutually inserted is formed between the top of the valve pad and the interior bottom of cavity respectively and is inserted
Hole.Or
The inserting column and slot being mutually inserted are formed between the sidepiece of the valve pad and the side wall of cavity respectively.
Using beneficial effect caused by the utility model：Because valve pad of the present utility model is inlaid in valve element bottom
In cavity, its installation is very convenient, and is to use eccentric grafting between valve pad and valve element cavity, during valve core rotation, valve pad
Follow valve element to rotate together, prevent valve pad from being slided with valve element, valve pad is hardly damaged, service life length.
Brief description of the drawings
Fig. 1 is the structural representation using the cylinder valve of the utility model core assembly；
Fig. 2 is the structural representation of the embodiment one of the utility model core assembly；
Fig. 3 is the structural representation of the embodiment two of the utility model core assembly.
Embodiment
Embodiment one
As shown in Figure 1, 2, a kind of core assembly, include in the valve body 1 blocking the blocking type valve element group of valve opening 2
Part, the bottom of the closure valve opening 2 of the valve element 3 of core assembly are fixed with valve pad 4.In the utility model, the valve pad 4 is inlaid in
In the cavity of the bottom of valve element 3, bias grafting at least one is set as between the valve pad 4 and cavity.In the present embodiment, the valve
The inserting column being mutually inserted and jack 5 are formed respectively between the top of pad 4 and the interior bottom of cavity.Because valve pad 4 is to be inlaid in valve element
3, its installation is very convenient, and is to use eccentric grafting between valve pad 4 and cavity, and when valve element 3 rotates, valve pad 4 is to follow
Rotate, valve pad 4 is hardly damaged, service life length.
Embodiment two
As shown in figure 3, unlike embodiment one, between the sidepiece of valve pad 4 and the side wall of cavity in the present embodiment
The inserting column being mutually inserted and slot 6 are formed respectively.
Claims (3)
1. a kind of core assembly, include in valve body blocking the blocking type core assembly of valve opening, the valve element of core assembly
The bottom of closure valve opening be fixed with valve pad, it is characterised in that：The valve pad is inlaid in the cavity of valve element bottom, the valve pad
Bias grafting at least one is set as between cavity.
2. core assembly according to claim 1, it is characterised in that：Divide between the top of the valve pad and the interior bottom of cavity
