Description
Technical field
The present invention relates to valve cock technical field more particularly to a kind of valve cock extension rods.
Background technology
Valve cock extension rod currently used in the market, there are two types of materials for the sealing means being connect with valve cock, a kind of
It is to use seal with elastometic washer, one is sealed with red steel paper；It is good with the sealing effect of seal with elastometic washer, use when dress used
It is small with torque, it is sealed with red steel paper, sealing effect is weaker, and needs assembly torque big；So using rubber currently on the market
Circle is in the majority come what is sealed, but since rubber ring will appear compressive deformation in use, when deformation to a certain extent, rubber
Circle can embrace valve inside mandril, lead to plug-hole, product failure.
Invention content
To solve technical problem present in background technology, the present invention proposes a kind of valve cock extension rod.
A kind of valve cock extension rod proposed by the present invention, including extend bar body, valve inside mandril, Gask-O-Seal and gear
Ring, it includes interconnecting piece and extension to extend bar body, and for interconnecting piece for being connect with valve cock, valve inside mandril is located in extension
Cavity in, gasket mounting groove is further opened between the inner wall between interconnecting piece and extension, Gask-O-Seal is fixed on close
It is tightly connected in packing mounting groove for being formed with valve cock, baffle ring is coaxially positioned within Gask-O-Seal inner circumferential, and baffle ring is close to be prolonged
One end of extending portion is fixedly connected with extension.
Preferably, baffle ring includes the linkage section, the first block section and the second block section that are linked in sequence in an axial direction, linkage section with
Extension is fixedly connected, and the first block section leans with Gask-O-Seal inner circumferential, and the second block section extends into the sky of interconnecting piece
Intracavitary.
Preferably, linkage section periphery is equipped with screw thread, and linkage section is connect by screw thread with extension.
Preferably, linkage section is interference fitted with extension inner wall.
Preferably, the first block section is interference fitted with Gask-O-Seal internal perisporium.
Preferably, baffle ring is integrally formed with extension.
Preferably, interconnecting piece inner wall is equipped with internal thread for being connect with valve cock.
Preferably, baffle ring inner wall is located at extension inner wall on same cylinder.
In the present invention, after valve cock extension rod is connect with valve cock, valve cock squeezes Gask-O-Seal, baffle ring limitation ring
The deformation of shape gasket avoids Gask-O-Seal from being pressed into the cavity of extension between baffle ring and gasket mounting groove
It results in blockage, solves the problems, such as the plug-hole caused by Gask-O-Seal deforms.
Description of the drawings
Fig. 1 is a kind of partial half view of valve cock extension rod proposed by the present invention.
Specific implementation mode
As shown in FIG. 1, FIG. 1 is a kind of partial half views of valve cock extension rod proposed by the present invention.
Referring to Fig.1, a kind of valve cock extension rod proposed by the present invention, including extend bar body, valve inside mandril 2, annular
Gasket 3 and baffle ring 4；It includes interconnecting piece 11 and extension 12 to extend bar body, and interconnecting piece 11 is connected for being connect with valve cock
11 periphery of portion is in regular hexagon, and 11 inner wall of interconnecting piece is formed with screw thread for being spirally connected with valve cock, and valve inside mandril 2, which is located in, to be prolonged
In the cavity of extending portion 12, the gasket mounting groove of annular, ring are further opened between the inner wall between interconnecting piece 11 and extension 12
Shape gasket 3 is fixed in gasket mounting groove, and after interconnecting piece 11 is connect with valve cock, valve cock is resisted against Gask-O-Seal
On 3, baffle ring 4 is coaxially positioned within 3 inner circumferential of Gask-O-Seal, and baffle ring 4 is fixedly connected close to one end of extension 12 with extension 12,
Therefore, Gask-O-Seal 3 is enclosed between baffle ring 4 and gasket mounting groove, and no matter what kind of deformation occurs for Gask-O-Seal 3
It will not all enter in the through-hole of extension 12 and cause plug-hole.
Specifically, baffle ring 4 includes linkage section 41, the first block section 42 and the second block section 43 being linked in sequence in an axial direction,
Linkage section 41, the first block section 42 and 43 internal orifice dimension of the second block section and outer diameter are equal, and 41 periphery of linkage section is equipped with screw thread, even
It connects section 41 to be spirally connected by the inner wall of screw thread and extension 12, first by 4 precession extension 12 of baffle ring when installation, then by Gask-O-Seal
3 fill in gasket mounting groove, and the first block section 42 leans with 3 internal perisporium of Gask-O-Seal, and the second block section 43 extends into
It in the cavity for entering interconnecting piece 11, is not contacted with Gask-O-Seal 3, the generation of 11 side of interconnecting piece is pressed to when Gask-O-Seal 3 is squeezed
When deformation, the second block section 43 can prevent above-mentioned deformation climb over baffle ring 4 enter extension 12 cavity in cause plug-hole.
It is connect in design method with the another kind of extension 12 in linkage section 41,41 periphery of linkage section does not have screw thread, connection
Section 41 is interference fitted with 12 inner wall of extension, can likewise ensure that baffle ring 4 will not fall off with extension.
Also a kind of design method about baffle ring 4, baffle ring 4 is integrally formed with valve cock extension rod, integrally formed excellent
Point is that baffle ring 4 will not occur to loosen and is even split away off from extension 12, improves the reliability of baffle ring 4.
First block section 42 is interference fitted with 3 internal perisporium of Gask-O-Seal so that Gask-O-Seal 3 is securely seated between close
Between packing mounting groove and baffle ring 4.
4 inner wall of baffle ring is located at 12 inner wall of extension on same cylinder, convenient for air-flow in the cavity of valve cock extension rod
Flowing.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
