Abstract
The utility model provides a low-temperature-resistant stop valve comprises a valve body, a through hole by which fluid passes in the valve body is provided with a valve clack, the contact part of the valve clack and the through hole is provided with a sealing device, the valve clack is movably connected at the bottom end of a valve rod which is sheathed in a valve cover, the valve cover and the valve body are hermetically connected into a whole through a hexagon bolt, a hexagon nut and a gasket, a packing box is arranged at the upper part of the valve cover, the packing box is internally filled with padding, the packing box compresses the internal padding through a packing press cover, the upper part of the valve rod is provided with threads, the top of the valve body is provided with a thread sleeve meshed with the threads on the valve rod, and the top end of the valve rod is fixedly connected with a hand wheel. The low-temperature-resistant stop valve has the beneficial effects of effectively sealing a container, avoiding leakage, and being convenient in use.
Description
Affiliated technical field
The utility model relates to a kind of stop valve, particularly a kind of low temperature resistant stop valve.
Background technique
The sealability of traditional stop valve is good inadequately, does not cause valve to freeze because sealing does not thoroughly have the fluid outflow, can cause enormous economic loss like this.
The model utility content
To the deficiency of existing technology, the utility model provides a kind of low temperature resistant stop valve.
To achieve these goals, the utility model solution technological scheme that its technical problem adopted is: a kind of low temperature resistant stop valve comprises valve body; The through hole that the valve inner fluid passes through is provided with flap, and flap and through hole contacting point are provided with seal arrangement, and flap is movably connected in the bottom of valve rod; Valve stem casing is in valve gap; Valve gap connects as one through hex head bolt, hexagon nut and pad and valve seal, is provided with Stuffing box on the top of valve gap, fills up filler in the Stuffing box; Stuffing box compresses inner stuffing through Gland; Be provided with screw thread on described valve rod top, the top of valve body be provided with valve rod on the thread bush of threaded engagement, be fixedly connected with handwheel on the top of valve rod.
Described hold-down grid lid closely is connected with valve gap through bolt.
Described valve body is the body of casting.
The beneficial effect of the utility model: the low temperature resistant stop valve that the utility model provides can seal, not reveal container effectively, and is easy to use.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
A kind of low temperature resistant stop valve comprises valve body 1, and through hole 7 places that valve body 1 internal flow passes through are provided with flap 2; Flap 2 is provided with seal arrangement 8 with through hole 7 contacting points, and flap 2 is movably connected in the bottom of valve rod 4, and valve rod 4 is enclosed within the valve gap 5; Valve gap 5 is tightly connected with valve body 1 through hex head bolt, hexagon nut and pad 3 and is one; Be provided with Stuffing box 9 on the top of valve gap 5, fill up filler 6 in the Stuffing box 9, Stuffing box 9 compresses inner stuffing 6 through Gland 10; Be provided with screw thread on described valve rod 4 tops, the top of valve body 1 be provided with valve rod 4 on the thread bush 11 of threaded engagement be fixedly connected with handwheel 12 on the top of valve rod 4.Described hold-down grid lid 10 closely is connected with valve gap through bolt.Described valve body 1 is the body of casting.The utility model working principle is rotated the straight line motion of reaching the standard grade that handwheel 12 can be realized valve rod 4, thus the contact of control flap 2 and through hole 7 with separate, and then carry out valve unlatching, close.
