Abstract
The invention discloses a threaded soft seal PP-R monotube loose joint gate valve, which comprises a valve body [1] and a valve plate [5], wherein a valve cover [7] is arranged above the valve body [1]; a valve shaft [8] is arranged in the valve cover [7]; one end of the valve shaft [8] is connected with the valve plate [5], while the other end is connected with a hand wheel [11]; the valve plate [5] comprises a framework and a rubber enwrapped on the framework to form a soft seal gate valve; a water inlet of the valve body [1] is provided with internal threads in threaded connection with a pipeline; and a water outlet end of the valve body [1] is connected with a PP-R short pipe [2]. The threaded soft seal PP-R monotube loose joint gate valve has high sealability, and is suitable for life demands of modern residents.
Description
Technical field
The present invention 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.
Summary of the invention
Purpose of the present invention just provides a kind of soft sealing gate valve, stop adamant by the time influence that gate valve is closed, satisfy a kind of screw thread soft seal PP-R single tube loose joint gate valve of modern resident living needs simultaneously.
The technical solution used in the present invention is: screw thread soft seal PP-R single tube 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 shaft in the valve gap, valve shaft one end is connected with flashboard, and the other end connects handwheel, it is levied is 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, is connected to pipeline to be threaded, and the waterexit end of valve body is connected with PP-R short tube.
Adopted technique scheme,, no longer needed groove in the valve body owing to adopt soft seal, increased the sealability of gate valve like this, because the valve inleting water end is provided with internal thread, the waterexit end is provided with PP-R short tube, in modern urbanite water consumption, can be good at being suitable for, thereby increased using scope greatly.
For reaching non-maintaining purpose, it is characterized in that in the described valve gap from up to down being two shoulder holes that increase successively, being provided with seal ring between the valve shaft 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 shaft with the hole wall scyewed joint, valve shaft is provided with annular boss above locking cap, stop valve shaft to move down by locking width of cloth extruding annular boss.Adopt such scheme, valve shaft 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, beneficial effect of the present invention is: because the present invention adopts soft sealing gate valve, it is good to close performance; Because two ends of valve body is respectively tapped hole and PP-R short tube, more can satisfy modern resident living needs, owing to avoid safeguarding, both energy-conservation cost of material has also reduced maintenance cost.
