Description
Technical field
The present invention relates to the valve technology field of control fluid on-off, more particularly to a kind of anti-tampering gate valves of telescopic band.
Background technology
At present, small towns, municipal water users are usually equipped with water meter to measure its water consumption on running water pipe road
;Tap water leakage causes the loss of water resource in order to prevent, usually closure gate valve is also equipped with before user's water meter, as tune
Section and cut-off equipment use;The refluence of medium influences the metering of user's water meter in order to prevent, and the management of water resource is caused
It is chaotic.
Such as Fig. 2, China Patent No. discloses a kind of loose joint one-way valve for 201120323528.4, including valve body 1, valve deck
2nd, opening and closing element 3, valve rod 4 and opening device, the valve deck 2 are arranged on 1 top of valve body, and the valve deck 2, which is equipped with, to be compressed
Nut 5, part is equipped with water inlet 11 and water outlet 12 vertically on the valve body 1, the opening and closing element 3 be arranged on into
Between the mouth of a river 11 and water outlet 12, described 4 one end of valve rod passes through clamp nut 5 and valve deck 2 and opening and closing element 3
Connection, the opening device are arranged on the free end of valve rod 4, and the opening device is handwheel 6, and the valve body 1 goes out
Integrally connected is equipped with check-valves 7 on 12 cavity of the mouth of a river, and the check-valves 7 is cone valve, and the spool 71 of cone valve leans on
The elastic compression of spring 72 is realized on valve seat 73 closes check-valves, when the pressure of the water inlet in 7 left side of check-valves is big
After the elastic force of spring 72, the spool 71 of check-valves 7 moves to right, and opens check-valves 7 and supplies water, when 7 right side of check-valves
Water outlet pressure be more than the pressure of left side water inlet plus the elastic force of spring 72 after, the spool of check-valves 7 71 is left
It moves, withstands valve seat, close valve, prevent originally aqueous reflux., by the present invention on the pipeline of tap water before water meter, no
The break-make of tap water can be only controlled, is also prevented from the refluence of tap water, avoiding the prior art, originally aqueous reflux causes water
The defects of meter amount is inaccurate facilitates the management of water resource；And pass through gear on the axially free end of the utility model valve body water outlet
When installing, replacing and repair way gate, rotation way gate is repeated without 360 degree for circle one union nut of flexible connection,
Need to only tighten or unscrew union nut can be easily accomplished installation or removal, but also be left during the way gate use
Following defect:
1st, the specification of water meter has size, and the size of control valve both sides interface is fixed, in order to connect water meter of different sizes,
It needs specially to go for the connecting tube of a transition, connects troublesome, and connector is more more more is susceptible to showing for leak
As；
2nd, all it is to be threadedly coupled between above-mentioned control valve and water meter, leak in order to prevent all can wind raw material in threaded connection place
Band prevents leak with this, but such connection is pretty troublesome, for babe in the wood, be frequently encountered and do not know
The problem of twining how many raw material bands, and such connection mode is also steeped there are raw material band with easily rotting long, being threadedly coupled mouth
The problem of getting rusty easily in water；
3rd, control valve or when pipeline maintenance, it is former after long-time use since pipeline material all has the phenomenon that expanding with heat and contract with cold
Some duct lengths can be a little variation, and the size of control valve is fixed, and replacement when is susceptible to size not
The phenomenon that matching;
It 4th,, must be again in pipe here since the length of control valve is fixed when pipeline burst occur needs the severing to reconnect
Connection one truncates pipe on road, brings and is inconvenient to pipeline maintenance.
5th, when mounted, the length for being frequently encountered pipeline reserves the situation of more point or a little less point, installation,
It repairs that inconvenient, using flexible degree is poor, is brought convenience to construction personnel's work.
