Abstract
The utility model relates to a wedge type rising stem manual gate valve with a lock. The gate valve comprises a valve body, a valve seat, a gate plate, a valve rod, a valve deck, an upper seal, sealing filler, a packing gland, a locking device, a support, a hand wheel, a sealing element and a mounting piece. The locking device is arranged on the support, and the locking device comprises a lock cylinder and a lock pin. A lock pin inserting hole is formed in one end of the hand wheel, when fixing is needed, the lock pin is inserted into the lock pin inserting hole, so that the lock cylinder is locked, and rotation of the hand wheel and the valve rod can be prevented. By means of the wedge type rising stem manual gate valve with the lock, locking can be achieved in the fully-opened and fully-closed state of the valve, manual hand wheel looseness or hand wheel looseness under other exceptional circumstances can be prevented, the positioning function and the locking function of the valve can be achieved, the applied range is wide, and mounting is convenient.
Description
Technical field
The utility model relates to valve technology field, specifically relates to the locking rising stem (RS.) hand sluice valve of a kind of wedge-type.
Background technique
The Wedge gate valve of currently available technology cannot lock under valve wide open or complete shut-down state, and handwheel is easily loosening, makes it that valve cannot be guaranteed long-term accurately location and in completely open and close state.Chinese patent CN2795579Y discloses a kind of formula high temperature cut-off valve of carving, and the valve rod of this gate valve is provided with limit stoper, and this limit stoper can play the object of flexible unlatching, but can not pin handwheel, and its application is subject to certain restrictions.
Summary of the invention
The purpose of this utility model is the shortcoming existing for prior art, and a kind of locking rising stem (RS.) hand sluice valve of wedge-type with position and lock requirement is provided.The locking rising stem (RS.) hand sluice valve of the utility model wedge-type comprises sealing on valve body, valve seat, flashboard, valve rod, valve gap, metal, stuffing box packing, Gland, locking device, support, handwheel and Sealing and assembling set, described flashboard is wedge-shaped structure, and between valve seat, form wedge-type seal pair, between described valve gap and valve rod, be provided with stuffing box packing, described stuffing box packing is compressed and is installed by sealing and Gland on metal, described support is provided with locking device, described locking device comprises lock core and lock pin, and one end of described handwheel is provided with lock pin patchhole.In the time of fixedly, lock pin is inserted to lock pin patchhole, lock core is pinned, to prevent the rotation of handwheel and valve rod.
The utility model beneficial effect is compared with prior art: under valve wide open complete shut-down state, can lock, with prevent artificial or other in particular cases handwheel is loosening, there is valve location and lock function, Applicable scope is wider, easy for installation.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Description of reference numerals: 1 is valve body, 2 is valve seat, and 3 is flashboard, and 4 is valve rod, and 5 is valve gap, and 6 seal on metal, and 7 is stuffing box packing, and 8 is Gland, and 9 is locking device, and 10 is support, and 11 is handwheel, and 12 is lock pin, and 13 is lock core.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: referring to Fig. 1, above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the locking rising stem (RS.) hand sluice valve of a kind of wedge-type, comprise valve body 1, valve seat 2, flashboard 3, valve rod 4, valve gap 5, on metal, seal 6, stuffing box packing 7, Gland 8, locking device 9, support 10, handwheel 11 and Sealing and assembling set, flashboard 3 is wedge-shaped structure, and between valve seat 2, form wedge-type seal pair, between valve gap 5 and valve rod 4, be provided with stuffing box packing 7, stuffing box packing 7 by metal, seal 6 and Gland 8 compress and install, support 10 is provided with locking device 9, locking device 9 comprises lock core 13 and lock pin 12, one end of handwheel 11 is provided with lock pin patchhole.In the time of fixedly, lock pin 12 is inserted to lock pin patchhole, lock core 13 is pinned, to prevent that handwheel 11 and valve rod 4 from rotating.
Finally, it should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, can also have many distortion.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all should think and belong to protection domain of the present utility model.
