Abstract

The utility model discloses a quick open-close and self-sealing type durable valve, comprising a water inlet pipe, an outlet pipe, a rotary knob, a screw rod, a fixed brake pad, an open-close brake pad, a spring thimble, a closing aid spring, a valve core cover, etc. A disc type rotary open-close mode is adopted, when a rotation open-close angle is only 45 DEG staying at four valve ports or 60 DEG staying at three valve ports; under a close state, by means of the support force of a spring and water pressure, the two contact planes of the open-close brake pad and the fixed brake pad are sealed automatically. The brake pad is made of hard wearproof metal materials, and the brake pad is durable. The utility model has the advantages of fast opening and closing, favorable automatic sealing performance, water saving, endurance and durability. The utility model is suitable for making various running water taps or other water valves.

Description

The durable valve of fast opening and closing selfsealings

The utility model relates to a kind of valve, especially relates to the durable valve of a kind of fast opening and closing selfsealings.

Angle of swing was bigger when existing running water valve opened and closed, and particularly the angle of swing of stop valve and gate valve is big; The sealing material poor sealing performance that causes, particularly ball valve easy to wear very easily wear and tear and can not coincide automatically the maintenance sealability and leak serious.Whether the closing direction of common cold water tap spool is opposite with water (flow) direction, needs to lean on the helical pressure pressurization at first to overcome the pressure ability throttle down of water, has accelerated the wearing and tearing of valve, so be not durable, also will rely on the spin sensation and the visual observation of hand close extremely when closing.

It is a kind of can fast opening and closing easy to use that the purpose of this utility model is to provide, from motive sealing, water saving, long-lived valve.

The purpose of this utility model be achieved in that the utility model comprise intake pipe, outlet pipe, knob, swing arm, fixedly brake lining, open and close brake lining, spool pack into sidewall circular hole, cartridge cover, help and close spring, spring thimble.Feature is to be processed with spool pack into sidewall circular hole, cartridge cover and sidewall circular hole scyewed joint in the middle of the sidewall at intake pipe and outlet pipe.Spool is by fixedly brake lining and the cooperation of keying brake lining are formed.Have for the hole that swing arm is installed in the middle of the brake lining, brake lining also is processed with permeable hole.Help an end that closes spring to withstand on the disk of thimble projection, on the keying brake lining on the other end top.The centre that opens and closes brake lining one side also is processed with the perpendicular [for the thimble installing and locating.Fixedly between a side of brake lining and the ring washer connecting part on the valve casing seal ring is housed, fixedly the opposite side of brake lining is helping folded mutually driving fit under the elastic force that closes bullet with the keying brake lining.

The utility model adopts to help and closes spring and withstand the keying brake lining, is helping under the elastic force effect of closing spring, open and close brake lining and fixedly the surface of contact of brake lining match.Again because adopting pressure by current will open and close brake lining with closing pressure active force in the same way compresses, and hydraulic pressure high more, close tightly more, automatic sealability is just good more.Abandoned elaxtic seal easy to wear owing to open and close surface of contact, therefore, the utlity model has fast opening and closing, easy to use, automatic good seal performance, water saving, long-lived advantage.

Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.

At intake pipe 7, be processed with the spool sidewall circular hole 21 of packing in the middle of the sidewall of outlet pipe 23, cartridge cover 13 connects with screw thread (24) with sidewall circular hole 21.Help an end that closes spring 11 to withstand on the thimble 12, the other end withstands on and opens and closes on the brake lining 10, and the centre that opens and closes brake lining 10 is processed with perpendicular interior I shape cylinder.One end of I shape is processed into square hole 32 in order to the square column head of swing arm 5 to be installed.The other end of I shape is processed into circular hole in order to the straight-bar end of thimble 12 to be installed, the other end of thimble 12 is processed into the dome triangle and withstands on the hemisphere recess 14 at cartridge cover 13 centers, the other end of swing arm 5 stretches out valve casing 20 external its top sections by the hole on the valve casing 20 16 knob 15 is installed, and knob 15 is fastening by nut 2.On the tapping 16 of swing arm 5 and valve casing 20 seal ring 4 is housed, seal ring 4 screws installation by cored screw 3, and fixedly the one side of brake lining 19 withstands on the ring washer 17 by seal washer 18, and fixedly the another side of brake lining 19 is directly folded driving fit mutually with the plane that opens and closes brake lining 10.Be processed with keyway 26 on the valve casing 20, fixedly be processed with key tenon 27 on the brake lining 19, keyway 26 matches with key tenon 27 and prevents that fixedly the brake lining rotation is guaranteed to open and close normally, is processed with keyway 25 on the valve casing 20, opens and closes and is processed with key tenon 29 on the brake lining 10 in order to the control keying accurately.

Fixedly be processed with stepping brake hole 28 on the brake lining 19, open and close to be processed with on the brake lining 10 and open and close lock hole 31, opening and closing brake lining 10 can rotate around swing arm 5 by the torsion of knob 15, its open and close lock hole 31 when overlapping fully with stepping brake hole 26 valve wide open open, the water of epicoele 8 flows in the cavity of resorption 22 smoothly; Valve contract fully when stagger fully with keying lock hole 31 in stepping brake hole 28, the water that can separate epicoele 8 fully enters in the cavity of resorption 22.

The numeral that does not below relate to is meant: 1 is the decorative plastic material, and 6 is the hexagon step, and hexagon step 6 is similar in appearance to hexagon nut, and 9 is screw thread.

Internal structure and Fig. 1 of Fig. 4 are identical, only outlet pipe 33 be processed into straight type and threaded coupling 35 is arranged and hexangle type step 34 so that and the pipeline use that links.The style of knob 30 can be selected as the case may be.
