Abstract
The utility model discloses a leak-proof valve, the valve seat is connected with an upper valve body, a water closing cover is arranged on the water closing end face of the valve seat, the water closing cover is connected with a lower valve rod, the lower valve rod is connected with an upper valve rod via the screw thread, the upper valve rod is sleeved with a lower spring seat, a spring and an upper spring seat, the upper spring seat is provided with a valve rod packing ring and a valve sealing gasket, the valve body is provided with a regulating nut connected with the upper valve rod screw thread, a handle is positioned on the upper end of the upper valve rod. When the utility model working, the valve is open or close, because the upper valve rod only has rotation but no axial movement, the abrasion for the packing ring is small, thereby effectively preventing producing leakage, greatly extending the service life of the valve, thereby, the utility model has the advantages of excellent sealing property, long service life and not easy leakage.
Description
Technical field:
The utility model relates to a kind of anti-leakage valve.
Background technique:
At present, valve of the prior art, as stop valve, gate valve etc., all be to adopt a valve rod mostly, and adopt packing seal, because in use, its valve rod also will be done axial motion when rotating, therefore be easy to the stuffing box packing wearing and tearing, thereby cause valve leak, shortened the working life of valve greatly.The using effect of therefore existing valve still is not ideal enough.
Summary of the invention:
The purpose of this utility model is: provide a kind of working life long, antileakaging anti-leakage valve, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it comprises valve seat (1), on valve seat (1), be connected with upper valve body (2), in valve seat (1), be provided with guiding rib (3), and water shutoff lid (4) is housed on the water shutoff end face of valve seat (1), on water shutoff lid (4), be provided with the guiding groove (5) that can be enclosed within on the guiding rib (3), on water shutoff lid (4), be connected with and cover the lower valve rod (6) that (4) relatively rotate with water shutoff, go up by the upper valve rod that has been threaded (7) at lower valve rod (6), in upper valve body (2), fix a upper valve rod positioning ring (8) is arranged, be with lower spring cup (9) on the upper valve rod (7) in upper valve body (2), spring (10) and upper spring seat (11), valve stem packing ring (12) and valve seal pad (13) are housed on upper spring seat (11), the adjusting nut (14) that is threaded with upper valve rod (7) is housed on valve body (2), on valve rod (7) and adjusting nut (14), all be provided with can installing and locating key (15) locating slot, the enclosure (16) is enclosed within on the adjusting nut (14), in the upper end of upper valve rod (7) handle (17) is housed; The guiding groove (5) that is located at the guiding rib (3) on the valve seat (1) and is located on the water shutoff lid (4) also can be exchanged mutually, promptly is provided with guiding groove (5) on valve seat (1), is provided with guiding rib (3) on water shutoff lid (4); On upper valve rod (7) and valve rod positioning ring (8), all be provided with vent (18).
Owing to adopted technique scheme, the utility model is compared with existing valve, the utility model is when work, when unlatching or throttle down, owing to having only to rotate, upper valve rod (7) do not have axial motion, therefore seldom to the wearing and tearing of seal ring, produce thereby prevented from effectively to leak, prolonged the working life of valve greatly, therefore, the utlity model has long, antileakaging advantage of good seal performance, working life, and the utility model also has the advantage of sealing load that can regulation valve body sealing gasket (13).When needing the sealing load of regulation valve body sealing gasket (13), can earlier handle (17) be unloaded, then the enclosure (16) and positioning key (15) are taken off, can pass through the position that adjusting nut (14) is regulated upper valve rod (7) like this, thereby adjust the pressure of spring (10) sealing gasket (13).
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the A-A cross-sectional schematic of accompanying drawing 1;
Embodiment:
Embodiment of the present utility model: valve seat (1) can be made into existing General valve structure shape or be made into the shape of water tap, during making, go up by a bolt connection upper valve body (2) at valve seat (1), and in valve seat (1), produce guiding rib (3), a water shutoff lid (4) is installed on the water shutoff end face of valve seat (1), and on water shutoff lid (4), produce the guiding groove (5) that can be enclosed within on the guiding rib (3), go up by its T-slot connection lower valve rod (6) at water shutoff lid (4), making lower valve rod (6) not cover (4) with water shutoff relatively rotates, go up by the upper valve rod (7) that is threaded at lower valve rod (6), in upper valve body (2), fix a last upper valve rod positioning ring (8), put lower spring cup (9) on the upper valve rod (7) in upper valve body (2), spring (10) and upper spring seat (11), and on upper spring seat (11), load onto valve stem packing ring (12) and valve seal pad (13), on valve body (2), install an adjusting nut (14) that is threaded with upper valve rod (7), on valve rod (7) and adjusting nut (14), all produce can installing and locating key (15) locating slot, the enclosure (16) is enclosed within on the adjusting nut (14), and a handle is installed routinely in the upper end of upper valve rod (7) (17).When making valve seat (1) and water shutoff lid (4), also guiding rib on it (3) and guiding groove (5) can be exchanged, promptly on valve seat (1), produce guiding groove (5), on water shutoff lid (4), produce guiding rib (3); In order to make lower valve rod (6) when moving, be subjected to littler damping, can on upper valve rod (7) and valve rod positioning ring (8), all open last 1～4 vent (18) and get final product.
