Abstract
The utility model discloses a multifunctional loose-joint type drip-leakage-preventing integrated check valve comprising a switch valve, wherein the water inlet end of the switch valve is provided with a check valve body (4); the check valve body (4) is internally provided with tapered check valve seat (3) and a valve plug support (7); the valve plug support (7) is provided with a tapered check valve plug (5) corresponding to the tapered check valve seat (3); a return spring (2) is arranged between the tapered check valve plug (5) and the valve plug support (7); and the end part of the check valve body (4) is provided with a loose joint (8). The tapered check valve seat (3) is provided with a rubber sealing ring (6) corresponding to the tapered check valve plug (5). The multifunctional loose-joint type drip-leakage-preventing integrated check valve can prevent water backflow and drip leakage and is simple in structure, convenient to manufacture and reliable in properties.
Description
Technical field
The utility model relates to a kind of valve, particularly relates to a kind of multi-functional loose joint formula leakage-proof non-return one valve.
Background technique
Tap water is not 6L/h per hour by the single water clock general speed of water meter measurement, and 24 hours water clock of single water tap can reach 150L, and is annualized, can reach more than 50 ton.For all kinds of pipe valves, tap, gondola water faucet and water meter, because of water meter starts insensitive, that the unusual water of a few users brings as put thread, drip etc. leakage loss and economic loss.Simultaneously, the metering dispute that water meter rotation that causes because of air in the pipeline and hydraulic pressure instability or counter-rotating cause is a difficult problem that is perplexing water supply department for a long time.And the valve of hot and cold water because the hot and cold water crossfire often appears in the fluctuation of hydraulic pressure, brings inconvenience to life for often opening in thermostatic control system, causes the water body cross pollution.And the connection of valve is very inconvenient at present.
The model utility content
Technical problem to be solved in the utility model provides and a kind ofly can prevent aqueous reflux and water clock and multi-functional loose joint formula leakage-proof non-return one valve quick and easy for installation.
In order to solve the problems of the technologies described above, the multi-functional loose joint formula leakage-proof non-return one valve that the utility model provides, comprise switch valve, feed-water end at described switch valve is provided with check valve body, be provided with conical shape check valve seat and spool supporting frame in the described check valve body, described spool supporting frame is provided with the conical shape check valve core corresponding with described conical shape check valve seat, be provided with return spring between described conical shape check valve core and described spool supporting frame, the end of described check valve body is provided with loose joint.
On described conical shape check valve seat, be provided with and the corresponding rubber seal of described conical shape check valve core.
Described switch valve is ball valve, gate valve or stop valve.
Adopt the multi-functional loose joint formula leakage-proof non-return one valve of technique scheme, open switch valve, when current enter and hydraulic pressure during greater than the elastic force of return spring from feed-water end, current promotion conical shape check valve core is moved to the left and makes one-way valve opens, otherwise when hydraulic pressure during less than the elastic force of return spring, the conical shape check valve core moves right under the effect of return spring, make closed check valve, small water flow can not pass through; When the water yield during less than the metering pressure of water meter, one-way valve can not opened, thus the purpose that reaches leakage-proof and prevent to flow backwards.The end of check valve body is provided with loose joint, makes valve quick and easy for installation.
In sum, the utility model is a kind ofly can prevent aqueous reflux and water clock and multi-functional loose joint formula leakage-proof non-return one valve quick and easy for installation, simple in structure, easily manufactured, reliable performance.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, feed-water end at ball valve 1 is provided with check valve body 4, be provided with conical shape check valve seat 3 and spool supporting frame 7 in the check valve body 4, spool supporting frame 7 is provided with the conical shape check valve core 5 corresponding with conical shape check valve seat 3, on conical shape check valve seat 3, be provided with the rubber seal 6 corresponding with conical shape check valve core 5, be provided with return spring 2 between conical shape check valve core 5 and spool supporting frame 7, the end of check valve body 4 is provided with loose joint 8.
Referring to Fig. 1, open ball valve 1, when current enter and hydraulic pressure during greater than the elastic force of return spring 2 from ball valve 1 feed-water end, current promotion conical shape check valve core 5 is moved to the left and makes one-way valve opens, otherwise, when hydraulic pressure during less than the elastic force of return spring 2, conical shape check valve core 5 moves right under the effect of return spring 2, makes closed check valve; When the water yield during less than the metering pressure of water meter, one-way valve can not opened, and like this, thereby small water flow can not be by the purpose that reaches leakage-proof and prevent to flow backwards.The end of check valve body 4 is provided with loose joint 8, makes valve quick and easy for installation.
Above-mentioned ball valve 1 can also replace with gate valve or stop valve.The utility model is widely used in all kinds of pipe valves, tap, gondola water faucet and the water meter.Be used in the thermostatic control system and can prevent the hot and cold water crossfire, service conduit internal water pressure balance prevents the water body cross pollution.Minimizing starts insensitive, that the unusual water of a few users brings as put thread, drip etc. leakage loss and economic loss because of water meter.Simultaneously, the metering dispute that can avoid the water meter rotation that causes because of air in the pipeline and hydraulic pressure instability or counter-rotating to cause has effectively solved these preferably and has perplexed the difficult problem of water supply department for a long time.The end of check valve body is provided with loose joint, makes valve quick and easy for installation.
