Abstract
Provided is a quick insertion type sluice valve. An expansion sleeve, a core body, a pipe clamp, a partition sleeve and an O-shaped sealing ring are sequentially arranged on a channel port of the lower portion of a valve body of the sluice valve from outside to inside. A groove is arranged at the outer end of the channel port of the lower portion of the valve body. Threads are not machined on a galvanized tube connected with the sluice valve. Heating adhesion is not required when the sluice valve is connected with a chlorinated polyvinyl chloride (CPVC) or crosslinked polyethylene (PEX) pipe. The sluice valve can be conveniently connected with a water pipeline without using other special tools.

Summary of the invention
The purpose of the utility model is to provide a kind of rapid plug-in gate valve; Need be on zinc-plated pipe when being connected with this gate valve machining screw; This gate valve does not need caking with CPVC or PEX pipe when being connected, need just can not be connected with pipeline easily by other specialist tools yet.
The technical solution that the utility model proposed is such:
A kind of rapid plug-in gate valve; Comprise valve body 6, flashboard 7, valve rod 8, valve gap 9, handwheel 10 and Sealing and fastening piece; Handwheel 10 drives the flashboard 7 that is positioned at the gate valve lower passage through valve rod 8 and opens or cut out; Said valve body 6 lower passage mouths from outside open cover 1, core body 2, pipe clamp 3, spacer 4 and O RunddichtringO 5 toward interior being provided with successively, said valve body 6 lower passage mouth outer ends are provided with groove.Said core body 2 is tubular; Its inner chamber from inside to outside is provided with first order step 2-4, second level step 2-5; The large diameter section 2-1 of core body 2 inner chambers and middle internal diameter section 2-2 intersection are first order step 2-4, and middle internal diameter section 2-2 and little internal diameter section 2-3 intersection are second level step 2-5.
Said pipe clamp 3 is funnel-like, on the body of pipe clamp 3, is covered with latch 3-1, and the exterior edge face 3-2 contact of pipe clamp 3 also is positioned on the first order step 2-4 of core body 2.Open cover 1 and be straight tubular, its inner end cover face is provided with annular barb 1-1, and the contact of this barb 1-1 hook face also is positioned on the second level step 2-5 of core body 2.
Said spacer 4 is loaded in the large diameter section 2-1 of core body 2 for the cirque body of band inner conical surface, leaves the gap between the body of its inner conical surface and said pipe clamp 3.O RunddichtringO 5 is contained in spacer 4 inboards of valve body 6 lower passage mouths.Said cover 1 the internal diameter ф 1 that opens should be greater than the external diameter ф that joined two pipes together, and circular diameter ф 2 should be less than the external diameter ф that joined two pipes together in the pipe clamp 3.
Compared with prior art, the utlity model has following beneficial effect:
The gate valve of the utility model be to adopt the rapid plug-in linkage structure by being connected of being joined two pipes together; The valve body lower portion passway installed successively open cover, core body, pipe clamp, spacer and O RunddichtringO after, just can realize and be tightly connected by the quick insertion of being joined two pipes together, joined two pipes together insert after; The pipe clamp compressive deformation; Each latch reach is kept a firm hand on and is joined two pipes together, and the pipe clamp exterior edge face still is close on the first order step of core body, is joined two pipes together so can not transfer to outward; Joined two pipes together and the valve body lower portion passage between through O RunddichtringO sealing, realize that gate valve is fastenedly connected with being sealed by the quick insertion between joining two pipes together.Compare with pipe connecting structure with existing gate valve, economize outlet pipe end tapping, twine sealing material and relevant process equipment, have the remarkable result quick, simple, convenient, that manufacturing efficiency is high is installed at threaded end.

Embodiment
Through following embodiment the utility model is done further to set forth in detail.
Referring to Fig. 1-shown in Figure 5, a kind of rapid plug-in gate valve is made up of valve body 6, flashboard 7, valve rod 8, valve gap 9, handwheel 10, Sealing, fastening piece and open cover 1, core body 2, pipe clamp 3, spacer 4 and the O RunddichtringO 5 that are installed in valve body 6 lower passage mouths.Core body 2 is tubular; Its inner chamber from inside to outside is provided with first order step 2-4, second level step 2-5; The large diameter section 2-1 of core body 2 inner chambers and middle internal diameter section 2-2 intersection are first order step 2-4, and middle internal diameter section 2-2 and little internal diameter section 2-3 intersection are second level step 2-5.Pipe clamp 3 is funnel-like, on the body of pipe clamp 3, is covered with latch 3-1, and the exterior edge face 3-2 contact of pipe clamp 3 also is positioned on the first order step 2-4 of core body 2.Open cover 1 and be straight tubular, cover face in end is provided with annular barb 1-1 within it, and the contact of this barb 1-1 hook face also is positioned on the second level step 2-5 of core body 2.Spacer 4 is the cirque body of being with inner conical surface, and it is installed in the large diameter section 2-1 of core body 2, leaves certain interval between the body of its inner conical surface and pipe clamp 3, and latch 3-1 deformation displacement leaves certain space during for pipe clamp 3 pressurizeds.O RunddichtringO 5 is contained in spacer 4 inboards of valve body 6 lower passage mouths.Inserting when being joined two pipes together, for making pipe clamp 3 compressive deformations, and promptly joined two pipes together, then require the internal diameter ф 1 that opens cover 1 to be a bit larger tham the external diameter ф that joined two pipes together, and circular diameter ф 2 will be slightly smaller than the external diameter ф that joined two pipes together in the pipe clamp 3 through the latch 3-1 of distortion.
During installation; Earlier O RunddichtringO 5 is contained in the valve body 6 lower passage mouth inner groovies; To open cover 1, pipe clamp 3, spacer 4 then and pack into successively in the core body 2, and these assemblies will be packed in the valve body 6 lower passage mouths, last; With this outer end, passway groove on special machine, accomplish the installment work of the quick insertion portion of gate valve.
