Abstract
The utility model discloses a valve with self-fastening flange joints. The valve comprises a valve main body, an end cover, a main body end joint and an end cover end joint, wherein the valve main body is combined with the main body end joint, the end cover is combined with the end cover end joint, and both the main body end joint and the end cover end joint are self-fastening flange joints. As the self-fastening flange joints are adopted by the valve, and the joints are combined with the valve, the problems of the traditional valve that the reliability is poor, and the possibilities of falling off, welling, dripping and leakage at a joint part are frequent can be thoroughly solved.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of valve with the self tightening flanged joint.
Background technique
The device that valve is blocked and opened as a kind of energy convection cell, its application is quite extensive.At present, valve commonly used all adopts conventional flange to be connected with pipeline, and its sealing is to lean on the plasticity extrusion-deformation of sealing gasket to realize.There are many drawbacks in this kind Placement: the first, sealing means causes the sealing gasket life-span short; The second, influenced by temperature difference stress etc., cause the axial bolts discontinuity, sealing was easily lost efficacy.Therefore, at present with the valve of this flanged joint, the not only feasible poor reliability that connects, and also the joint easily produces the problem of run, drip, leak.These all can bring greatly economic loss to enterprise, bring serious hidden danger to safety in production.
The model utility content
The purpose of this utility model just is to provide a kind of valve with the self tightening flanged joint, can solve above-mentioned valve reliability difference and joint fully and easily produce the problem of run, drip, leak.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of valve with the self tightening flanged joint, comprise valve body, end cap, bulk end joint and end cap end connector, described valve body and bulk end joint disjunctor, described end cap and end cap end connector disjunctor, bulk end joint and end cap end connector are the self tightening flanged joint.
Compared with prior art, advantage of the present utility model is: this valve is owing to adopted the self tightening flanged joint, and joint and valve disjunctor, makes it solve the conventional valves poor reliability fully and the joint easily produces the problem of run, drip, leak.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, a kind of valve with the self tightening flanged joint, comprise valve body 1, end cap 2, bulk end joint 3 and end cap end connector 4, described valve body 1 and bulk end joint 3 disjunctors, described end cap 2 and end cap end connector 4 disjunctors, bulk end joint 3 and end cap end connector 4 are the self tightening flanged joint.
During use, the self tightening flange that cooperates the patent No. 200720079783.2 to be announced uses and gets final product.The utility model is owing to adopted self tightening bulk end joint 3 and end cap end connector 4, and valve body 1 and bulk end joint 3 disjunctors, and end cap 2 and end cap end connector 4 disjunctors, make it solve the conventional valves poor reliability very completely and the joint easily produces the problem of run, drip, leak.Such structure had both changed the unreasonable of Placement, had strengthened its reliability again greatly, and this structure belongs to domestic initiation.
