Abstract
The utility model discloses a flexible-seal female-thread-union gate valve, which comprises a valve body [1] and a flashboard [5]. A bonnet [7] is arranged above the valve body [1]. A valve stem [8] is arranged in the bonnet [7]. One end of the valve stem [8] is connected with the flashboard [5] and the other end of the valve stem [8] is connected with a hand wheel [11]. The flashboard [5] comprises a skeleton and rubber which is wrapped on the skeleton to form the flexible-seal gate valve. Female threads are arranged at the water inlet of the valve body [1]. The water outlet end of the valve body [1] is connected with an insertion tube [2]. Grooves are arranged on the external circular surface of the insertion tube [2]. The flexible-seal female-thread-union gate valve has the advantages that the sealing performance is good, the valve is convenient and rapid to assemble and disassemble, the efficiency is high, material costs are saved and maintenance expenses are reduced.
Description
Technical field
The utility model relates to soft sealing gate valve.
Background technique
Gate valve is widely used in the productive life field.Gate valve generally comprises valve body and valve plate, and existing valve body two ends are typically provided with flange, realize by flange when being connected with pipeline.Simultaneously existing gate valve is hard seal gate valve, because the valve body fluid passage of hard seal gate valve is provided with the groove suitable with valve plate, when adamant such as sand was arranged in the fluid, can be trapped in influenced closing of gate valve in the groove.In addition, along with the development of modern new material, very big variation has also taken place in the applied environment of gate valve, in resident living, the pipeline that supplies water to the resident generally is a metallic conduit, and mostly the water pipe in the resident family is PP-R, and flange connection often can not satisfy above-mentioned resident's living needs.Along with the development of modern times pipe industry technology, various new material pipe fittings emerge in an endless stream, and it is fast convenient directly to peg graft, and the efficient height becomes a kind of demand.
The model utility content
The purpose of this utility model just provides a kind of soft sealing gate valve, stop adamant by the time influence that gate valve is closed, the soft seal internal thread loose joint gate valve that can peg graft fast.
The technical solution adopted in the utility model is: soft seal internal thread loose joint gate valve, it comprises valve body and is positioned at the flashboard of valve body, the top of valve body is provided with the valve gap that cooperates with it, be provided with valve rod in the valve gap, valve rod one end is connected with flashboard, the other end connects handwheel, it is characterized in that described flashboard comprises that skeleton and the rubber that is wrapped on the skeleton constitute soft sealing gate valve, the water intake of described valve body is provided with internal thread, be connected to pipeline and be threaded, the waterexit end of valve body is connected with intubate, with the pipeline socket connection, the periphery of intubate is provided with groove, the convenient sealing of pegging graft.
Adopted technique scheme, owing to adopt soft seal, no longer need groove in the valve body, increased the sealability of gate valve like this, because the valve inleting water end is provided with internal thread, intubate is established in the waterexit end, in modern urbanite water consumption, can be good at being suitable for, thereby increased using scope greatly, the intubate installation of when installing and using, can directly pegging graft, quick and convenient, the efficient height.
For reaching non-maintaining purpose, from up to down two shoulder holes that increase successively in the valve gap, being provided with seal ring between the valve rod of upper shoulder hole and the hole wall seals body cavity, be provided with locking cap between the hole wall of middle shoulder hole and the valve rod with the hole wall scyewed joint, valve rod is provided with annular boss above locking cap, stop valve rod to move down by locking width of cloth extruding annular boss.Adopt such scheme, valve rod is positioned in the step hole, no longer need seal pressure with union (screwed)bonnet (UB above valve gap, has saved maintenance, has saved cost.
In sum, the utility model beneficial effect is: because the utility model adopts soft sealing gate valve, good seal performance; Because two ends of valve body is respectively tapped hole and intubate, more can satisfy modern resident living needs, assembling and disassembling is fast convenient, the efficient height; Owing to avoid safeguarding, both energy-conservation cost of material has also reduced maintenance cost.
