The bottom valve for the single-base tank is characterized in that a tank bottom flange and a supported flange fix a valve body by virtue of bolts, a cover plate is connected with a support, the support is connected with a lower cylinder cover of a cylinder, a piston assembly is arranged between an upper cylinder cover of the cylinder and the lower cylinder cover of the cylinder, a spring is arranged between the piston assembly and the upper cylinder cover of the cylinder, a valve rod seal ring is inlaid into a seal groove of a valve rod, a valve rod sealing element is matched with a cover plate and a guide sleeve, a lip-shaped sealing element and a wear-resistant sleeve are matched with the valve rod in a sliding manner, and an expansion piston ring is inlaid in the seal groove of the piston assembly.
Description
Technical field
The utility model relates to a kind of single seat tank bottom valve.
Background technique
The single seat tank bottom valve is widely used in the pipe-line system in multiple fields such as beer, dairy products, pharmacy, chemical industry, beverage.
Used in the market single-seat valve ubiquity complex structure, the flowability to product is gone up in the valve body design, and cleaning does not all reach desirable effect.And dismounting is difficult for.Be not easy to operational maintenance and maintenance.
The model utility content
In order to overcome above-mentioned technical problem, the utility model provides a kind of single seat tank bottom valve.
Concrete technological scheme is following:
A kind of single seat tank bottom valve is characterized in that, jar end flange and supported flange are fixed together valve body through bolt; Cover plate is connected with support; Cylinder cap is connected under support and the cylinder, and piston assembly is installed under cylinder upper cylinder cover and the cylinder between the cylinder cap, and spring is installed between piston assembly and the cylinder upper cylinder cover; Valve stem packing ring is embedded in the seal groove of valve rod; Valve rod sealing member cooperates with cover plate, guide sleeve, and lip packing, wear-resistant sleeve cooperate with valve stem slides, and the expansion piston ring is embedded in the seal groove of piston assembly.
The single seat tank bottom valve of the utility model, special sealing contact structures reduce the wearing and tearing of Sealing.The valve inner spherical designs reduces the pressure loss, the inner cleaning of being more convenient for.The jar end flange of thickening has reduced the distortion of welding rear valve body, and a valve body and jar Placement of end flange clamp band type have flexible row highly, and easy accessibility is simple.The valve design of special construction has reduced the residue problem of medium.Valve can change opening state fast and often open/and normally closed.Can be according to different pressure requirements, valve body and final controlling element mate again.Intelligent controller can be matched or position transducer carries out telecontrol according to the different working state.Aesthetic property with bigger Security, durability, cleanliness and outward appearance.
Description of drawings
Fig. 1 is the utility model single seat tank bottom valve structural representation.
Among the figure: flange at the bottom of the 1-jar, 2-supported flange, 3-expansion piston, 4-valve body; The 5-lip packing, the 6-cover plate, the 7-support connects, the 8-guide sleeve; The 9-piston assembly, 10-spring, 11-cylinder upper cylinder cover, 12-wear-resistant sleeve; The 13-valve rod sealing member, cylinder cap under the 14-cylinder, 15-valve stem packing ring, 16-valve rod.
Embodiment
In conjunction with accompanying drawing the utility model is done and to be further described.
A kind of single seat tank bottom valve is characterized in that, a jar end flange 1 is fixed together valve body 4 through bolt with supported flange 2; Cover plate 6 is connected with support 7; Cylinder cap 14 is connected under support 7 and the cylinder, and piston assembly 9 is installed under cylinder upper cylinder cover 11 and the cylinder between the cylinder cap 14, and spring 10 is installed between piston assembly 9 and the cylinder upper cylinder cover 11; Valve stem packing ring 15 is embedded in the seal groove of valve rod 16; Valve rod sealing member 13 cooperates with cover plate 6, guide sleeve 8, and lip packing 5, wear-resistant sleeve 12 are slidingly matched with valve rod 16, and expansion piston ring 3 is embedded in the seal groove of piston assembly 9.
At last, it is also to be noted that what more than enumerate only is the practical implementation example of the utility model, obviously, the utility model is not limited to above examples of implementation, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought the protection domain of the utility model.
