Description
Technical field
The utility model belongs to drainage pipeline field, more particularly to a kind of conduit switch valve.
Background technique
Valve is the control unit in fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents adverse current, pressure stabilizing, shunting
Or the functions such as overflow pressure relief.Existing many equipment (using water) do not have protection against leakage, or have detected whether leakage using electronic type,
And water route is closed with solenoid valve.Existing liquid plant has many insufficient places, mainly includes following two points:
1, without protection against leakage, a large amount of leakage accidents are easy to appear；
2, electronic type valve cannot be detected in power failure, and overall cost is high, need PCB, detection probe, solenoid valve etc.
Structure, complicated integral structure, poor reliability.
Summary of the invention
For the defect for solving existing aqueduct valve leak water detdction complexity, we have proposed a kind of conduit switch valves, pass through letter
Single mechanical system detection leak simultaneously closes water pipe access in time.
The utility model is achieved through the following technical solutions:
A kind of in order to achieve the above object, the utility model provides conduit switch valve, including it is valve body, sealing ring, dynamic
Make spool, expansion piece and valve seat, wherein valve body is hollow, and water outlet is arranged at top, and there is water inlet normal thereto in side；It enters and leaves
The mouth of a river guarantees valve both ends energy Inlet and outlet water, so that valve becomes a part of fluid passage.
Wherein movement spool is fitted closely in valve body interior side, and passes through sealing ring and valve body interior side
It is held against, is flushed at the top of movement spool with water inlet bottom, there is the unimpeded mistake of the enough water flows in gap between water outlet and water inlet；
Movement spool is device functionality main part, controls whether water flow is truncated by acting the movement of spool.
Wherein valve body bottom is connected with valve seat, and movement spool bottom is connected with water swelling piece, water swelling piece bottom
Valve seat top surface is tightly attached in portion, and there are the expansion spaces of water swelling piece for the hollow structure of valve body and valve seat composition；Wherein
Seat bottom portion hole connecting valve hollow space and the external world；Water swelling piece is and valve where acting the motive force of spool
Seat and valve body separate, and can replace new water swelling piece at any time, improve life of valve.
Preferably, above-mentioned valve body is made of metal or plastics, keeps and water pipe one, corrosion-resistant, extension service life.
Preferably, above-mentioned water swelling piece is made of water-absorbing resin.
The beneficial effects of the utility model are:
1, valve service life and accuracy can effectively ensure that using mechanical structure；
2, valve body and the split type replaceable water swelling piece of setting of valve seat, recycled for multiple times；
3, low in cost.

Specific embodiment
The technical issues of in order to keep the utility model solved, technical solution and beneficial effect are more clearly understood, below
In conjunction with accompanying drawings and embodiments, the present invention will be further described in detail.It should be appreciated that specific implementation described herein
Example only to explain the utility model, is not used to limit the utility model.
Embodiment 1
Refering to fig. 1, a kind of conduit switch valve, including valve body 1, sealing ring 2, movement spool 3, expansion piece 4 and valve seat
5, wherein valve body is hollow, and water outlet is arranged at top, and there is water inlet normal thereto in side；Movement spool is fitted closely in valve
Body interior side, and be held against by sealing ring and valve body interior side, at the top of movement spool and water inlet bottom
It flushes, there is the unimpeded mistake of the enough water flows in gap between water outlet and water inlet；Valve body bottom is connected with valve seat, acts spool bottom
Portion is connected with water swelling piece, and valve seat top surface, and the hollow knot of valve body and valve seat composition are tightly attached in water swelling piece bottom
There are the expansion spaces of water swelling piece for structure；Seat bottom portion hole connecting valve hollow space and the external world.
Referring to Fig.2, the course of work is as follows: under normal state, expansion piece is fully locked status, and movement spool decline, top is stayed
There is space, liquid enters from the inlet, and across the space of valve body interior, flows out from water outlet.When water pipe access leak,
Liquid flows on the outside of valve, and in bottom ponding, ponding enters expansion piece by the hole of seat bottom portion, so that expansion piece
Expansion becomes larger, and movement spool is jacked up, entire valve body interior space is full of, when valve body interior is full of, from water inlet
The liquid that mouth enters can not be discharged from water outlet, and water pipe access stops water flowing with regard to this truncation, reach and close water pipe access, reduction
The purpose of loss.
Embodiment 2
Refering to Fig. 2 and Fig. 4, a kind of conduit switch valve, including valve body 1, sealing ring 2, movement spool 3,4 and of expansion piece
Valve seat 5, wherein be truncated conical shape at the top of movement spool, improve it is mobile after leakproofness, remaining structure and working principle and implementation
Example 1 is consistent.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
