Abstract
The utility model relates to a pipeline fitting which is used for preventing fluid transportation from out of control, comprising a shell, a fixation ring which is separately arranged at the two sides of the shell inner side and a spring which is connected with each fixation ring. The utility model is characterized in that a section of shell between the fixation rings is provided with a concave slot and thin wall structure, an airproof ring is arranged between the fixation rings, a choke plug of which the maximum radius vector is bigger than the inner hole diameter of the airproof ring is arranged between each airproof ring and spring, the choke plug is fixedly connected with the other end of the spring, a support block which is clamped between the choke plugs is arranged in the shell. The utility model provides the advantages of simple structure, easy manufacture, being able to protect fluid transportation pipeline in case of emergency, few fluid leakage, reliability, safety and low cost.
Description
The utility model belongs to the fluid delivery system field, is specifically related to a kind of pipeline fittings that prevents that FLUID TRANSPORTATION is out of control.
At present, in fluid (as gasoline, the rock gas) delivery line, to connect two sections pipelines by attachment valve.Often need pulling one section pipeline wherein in the actual job.For example, the pipeline that connects with movable equipment needs the pull fluid delivery pipe when equipment moves.In the case, pipeline is very easily broken, and causes the fluid leakage phenomenon, and serious meeting causes the accident disaster, injures fluid delivery pipeline crowd on every side.The Pull breaking ualve that fluid was revealed when being used for of prior art prevented that pipeline from being broken, adopt following scheme: retaining ring is equipped with at two ends in the housing, and fixing spring on each retaining ring connects the taper plug on the spring.When housing was broken, the taper plug was ejected by spring, with the housing bore seal, in case fluid is revealed.But this Pull breaking ualve require on taper plug and the shell inner surface cooperate must be tight, the requirement on machining accuracy of fitting surface is very high, could effectively prevent the fluid leakage like this.Because the taper plug of this Pull breaking ualve is difficult to realize on processing technique, and cost is higher.Therefore, less economical on using, be unfavorable for promoting the use of on a large scale.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of fluid delivery pipeline safety attachment valve that can ensure that fluid delivery pipeline is safe and reliable, simple in structure and be easy to make is provided.
For achieving the above object, the utility model adopts following technological scheme: design a kind of fluid delivery pipeline safety attachment valve, comprise the housing of being with inner chamber, both sides are provided with retaining ring respectively in housing, connect a spring on each retaining ring, it is characterized in that the piece housing between the retaining ring adopts the groove thin walled structures, place between the retaining ring of housing both sides in the inner chamber of groove thin-walled both sides seal ring with holes respectively is set, the plug of maximum radius vector greater than the ring inner hole diameter is set between each seal ring and the spring, plug is fixedlyed connected with the other end of spring, support block is set in the housing, and the support block pinching is between the plug of housing both sides.
Plug of the present utility model can be spheroid or circular cone stage body, and the greatest circle diameter of the diameter of spheroid or circular cone stage body is greater than the diameter of ring inner hole.
The utility model is simple in structure, is easy to make, and can in case of emergency protect fluid delivery pipeline, and fluid is revealed few, and is safe and reliable; Owing to adopted a lot of standardized components, therefore, interchangeability is strong, and cost is low.
The utility model is done the explanation in a nearly step below in conjunction with accompanying drawing.
Structural representation when accompanying drawing 1 is the utility model embodiment's a FLUID TRANSPORTATION state;
Fig. 2 is the structural representation when pipeline is broken state among the utility model embodiment.
As shown in Figure 1: two ends are provided with retaining ring 1,9 respectively in housing, fixedly connected spring 2,8 on the retaining ring 1,9, seal ring 4,6 is set between the spring 2,8, fixedly connected stifled ball 3 on the spring 2, fixedly connected stifled ball 7 on the spring 8, pinching support block 5 between the stifled ball 3,7, the length of support block 5 should guarantee that spring 2,8 is contraction state.Under the effect of support block 5 and spring, stifled ball keeps static equilibrium.Under this state, fluid just can be in the cavity of housing 10 flows in the endoporus of the hole on retaining ring 1,9, seal ring 4,6.
When moving the equipment connect with pipeline or other and need spur pipeline, owing to causing pulling force excessive accidentally.Because housing 10 intermediate portions are the thin-walled ring, therefore very easily broken.Housing 10 disconnects from middle position, and support block 5 drops.Stifled ball 3 is under the elastic force effect of spring 2, and immediately bullet is to seal ring 4, with its endoporus sealing.Like this, fluid just can not flow out in the endoporus of seal ring 4.Thereby guaranteed the safety of fluid delivery pipeline, unlikely leak fluid.Pipeline when preventing that effectively housing 10 from being broken is revealed, and the diameter of stifled ball 3 should be greater than the diameter of bore of seal ring 4.
