Abstract
The utility model discloses a kind of dual stop valve, comprise stop valve base, described stop valve base is provided with valve body, described valve body is provided with valve gap, in described valve gap, valve rod is installed, described valve stem top is provided with bull stick, and described stem bottom is provided with the first spherical valve core, is provided with the second spool outside described first spherical valve core; Described valve body comprises by the interconnective water-inlet cavity of inwall, water chamber and spool chamber, and described water-inlet cavity top offers the first spherical valve core bore, and described second spool is connected with spool chamber inwall.The dual stop valve of one described in the utility model, installs the leakage of anti-fluid together with the second spool by valve body first spherical valve core, coordinate the first seal ring, the second seal ring simultaneously, the 3rd seal ring effectively protects fluid outflow, economize on resources.
Description
Technical field
The utility model relates to fluid machinery technology, especially a kind of dual stop valve.
Background technique
Present most of stop valve is a monomer cut-off fluid, or uses spherical valve or use three-dimensional, and in use getting rusty due to long-term wearing and tearing to cause cut-off effect to decline, and needs more exchange device, time-consumingly takes a lot of work.
Model utility content
The purpose of this utility model is to provide a kind of dual stop valve; the leakage of anti-fluid is installed together with the second spool by valve body first spherical valve core; coordinate the first seal ring, the second seal ring simultaneously, the 3rd seal ring effectively protects fluid outflow, economize on resources.
In order to achieve the above object, the technical solution of the utility model is:
A kind of dual stop valve, comprise stop valve base, described stop valve base is provided with valve body, described valve body is provided with valve gap, in described valve gap, valve rod is installed, described valve stem top is provided with bull stick, and described stem bottom is provided with the first spherical valve core, is provided with the second spool outside described first spherical valve core; Described valve body comprises by the interconnective water-inlet cavity of inwall, water chamber and spool chamber, and described water-inlet cavity top offers the first spherical valve core bore, and described second spool is connected with spool chamber inwall.
Described valve rod is provided with the first seal ring, described first spherical valve core is provided with the second seal ring, described second spool is provided with the 3rd seal ring.
Described valve body offers the first lightening core and the second lightening core.
The beneficial effects of the utility model are: the dual stop valve of one of the present utility model; the leakage of anti-fluid is installed together with the second spool by valve body first spherical valve core; coordinate the first seal ring, the second seal ring simultaneously, the 3rd seal ring effectively protects fluid outflow, economize on resources.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment 1
A kind of dual stop valve as shown in Figure 1, comprise stop valve base 1, described stop valve base 1 is provided with valve body 2, described valve body 2 is provided with valve gap 3, in described valve gap 3, valve rod 4 is installed, described valve rod 4 top is provided with bull stick 5, is provided with the first spherical valve core 6 bottom described valve rod 4, is provided with the second spool 7 outside described first spherical valve core 6; Described valve body 2 comprises by the interconnective water-inlet cavity 8 of inwall, water chamber 9 and spool chamber 10, and described water-inlet cavity 8 top offers the first spherical valve core bore 11, and described second spool 7 is connected with spool chamber 10 inwall.
Described valve rod 4 is provided with the first seal ring 12, described first spherical valve core 6 is provided with the second seal ring 13, described second spool 7 is provided with the 3rd seal ring 14.
