Abstract

The utility model relates to a valve of an O-shaped seal ring, which has no threaded connection, no need of radial direction, such as break valve, globe valve and plug valve. The valve comprises an internal core tube, a valve body, a locking piece, a seal ring and a fixing device. The valve is different in that the position arranged at the external wall of the valve and close to the end head is provided with threads, and the internal valve is a cone platform shape inclined plane; the locking piece is a cone platform shape flowering sleeve, the angle of taper of the external lateral is corresponding to the cone platform shape of the internal tube; An interstitial space used for containing the waiting connect tube is arranged between the wall of the internal hole and the core tube; the seal ring is a common O-shaped seal ring; the fixing device is a threaded sleeve whose internal wall is provided with threads corresponding to the threads arranged at the external wall of the tube body; the internal core tube is a thin metal tube arranged independently and used for bearing the waiting connect tube. When making the utility model, the valve main body and the threaded sleeve are capable of being made of plastic and metal, the internal core tube is made of metal, and the flowering sleeve is made of plastic.

Description

A kind of valve
The utility model relates to a kind of valve that rib-loop connects that do not have, as stop valve, ball valve, stopcock.
Existing valve utilizes the rib-loop connection to be connected two kinds with non-rib-loop, for pipe that can not the Cairo line as aluminium-plastic composite pipe etc., adopt has the radially valve of O RunddichtringO more, this kind valve must apply external force the O RunddichtringO is pressed on realization sealing on the body when connecting, but in order to compress the O RunddichtringO, body is deformed, the plastics of extrusion are aging easily, and aging stratification will take place the aluminium-plastic composite pipe of heat processing and forming, cause the body seepage.
The purpose of this utility model provides a kind of radially valve of O RunddichtringO that need not.
The purpose of this utility model is achieved in that this novel valve comprises valve body, locking element, fixing device, seal ring and inner core tube, and different is: near the end, have screw thread, and the inside end is the truncated cone inclined-plane on the outer wall of described valve body; Described locking element is the truncated cone cover of blooming, and the tapering of its outer side surface and body truncated cone inside is corresponding, stays between its inner hole wall and the core pipe and can hold the slit of waiting to take over body; Described fixing device is a threaded sleeve, offer on the madial wall of this threaded sleeve with tube wall on offer the corresponding screw thread of screw thread: described seal ring is common O RunddichtringO; Described inner core tube is for supporting the independent thin metal pipe of installing of waiting to take over body.
Because this novel valve is when connecting body, body to be taken over is in the core pipe and blooms between the cover, when threaded sleeve and body screw, threaded sleeve pushes the cover of blooming, make it will to wait to take over press to the core pipe and fixing and compression axis to the seal ring sealing, to bear external force little owing to wait to take over, and more need not distortion, then can not make and wait to take over aging seepage.And the cover bottom is provided with the effect that O-ring seal can be played in the leakproof foundation ring because bloom, and again because outside the interior ring of leakproof foundation ring, the mouth of hook that has a circle to protrude inwards can hook and treat the junctor inwall, has more strengthened treating the leakproof of taking over body.Fig. 1 is a prevailing mode of execution of the present utility model, and concrete when implementing the utility model, the material of valve body, threaded sleeve can be with plastics or metal, and inner core tube is a metal, and the cover of blooming is plastics.
Below in conjunction with accompanying drawing technical elements of the present utility model is further described.
Fig. 1 is the utility model valve mechanism schematic representation;
Fig. 2 is the structural representation of blooming and overlapping.
Valve body 1, threaded sleeve 3, all available plastics or metal are made.Offer screw thread by the port on valve body 1 outer wall, the inner hole wall of the inside then is receives little truncated cone inwards; Core pipe 4 is made of metal: cover 2 the endoporus of blooming is cylindrical and outer side surface is taper type, its size is corresponding with valve body 1 inwall circular cone that front end is with tapering, in order better to seal leakage proof, a leakproof foundation ring 7 can be established in cover 2 the bottom of blooming, the interior ring place of leakproof foundation ring 7 also can establish the mouth of hook 8 that a circle protrudes inwards, in order to increase friction, blooming also is provided with the boss 9 that a circle protrudes on cover 2 the inner hole wall, offer on the inner side surface of rib-loop sleeve pipe 3 with valve body 1 outer wall near the corresponding rib-loop of Cairo, port place line.When connection is waited to take over body, waiting to take over body 6 inserts in cover 2 endoporus of blooming, wait that the port of taking over body 6 withstands on the leakproof foundation ring 7 of the cover of blooming, the mouth of hook 8 at ring place hooks and waits to take over body 6 port inner hole walls in the leakproof foundation ring 7, wait that with what be with the cover 2 of blooming taking over body 6 inserts between core pipes 4 and the valve body 1, rib-loop sleeve pipe 3 is placed in waits to take over outside the body 6, and be tightened in the valve body 1; When the rib-loop sleeve pipe screwed and be mobile inwards, the extruding cover 2 of blooming moved inwards, and the outer side wall of the cover 2 of blooming is inwardly pressed by the extruding of valve body 1 madial wall and waited to take over body 6, realize fastening, and seal ring 5 anti-leaks of compression axis.
