Abstract
The urgent Pull breaking ualve of the utility model, comprise left check valve body and right check valve body, also comprise the snap ring be sleeved on left check valve body, be sleeved on the limited ring of left check valve body root, claw is evenly distributed on limited ring by locating stud, claw one end is stuck on snap ring, and the other end is stuck on right check valve body.Left check valve body and right check valve body inside symmetrically structure; the design uses structure and the claw of caliper type; claw connects left check valve body and right check valve body protective conduit is unaffected when breaking; add on-the-spot Security, claw is arranged on limited ring simultaneously, does not affect the handling of material; the very little moment of operator's misoperation is also avoided to break valve body easily; cause false alarm, structural design is simple, easy to use.
Description
Technical field
The utility model relates to Pull breaking ualve technical field, especially a kind of urgent Pull breaking ualve.
Background technique
In the course of conveying of high-pressure liquid, usually occur because the carelessness of tank car driver, cause tank car and slip car and the material from leakage that causes conveyance conduit to be broken causing, cause great harm to on-the-spot equipment and personnel.In this case, this annex of urgent Pull breaking ualve is when breaking situation and occurring, and break the valve of design, protective conduit is unaffected, increases on-the-spot Security.
Existing Pull breaking ualve adopts steel ball to locate mostly, the mode that centre arranges sliding sleeve fixes left and right valve body, by pulling sliding sleeve to disconnect left and right valve body, thus the flap of body inside, left and right two reset under the action of the spring come each self-enclosed come protective conduit, now, left and right two bodies insert in its valve body chamber mutually, seal by the O shape circle in pressure-bearing body, and such structure easily causes and causes leakage because of the axial sealing pressure born of O shape circle; Simultaneously because adopt steel ball location to cause the rotation of left and right valve body, impact handling material; Two bodies about being located by connecting by steel ball in addition, middle flap because operator just can pull open very easily with the misoperation of very little moment, can cause valve body to break, and causes false alarm.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of caliper type, the simple urgent Pull breaking ualve of structure.
The technological scheme realizing the utility model object is: urgent Pull breaking ualve, comprise left check valve body and right check valve body, also comprise the snap ring be sleeved on left check valve body, be sleeved on the limited ring of left check valve body root, claw is evenly distributed on limited ring by locating stud, claw one end is stuck on snap ring, and the other end is stuck on right check valve body.
As optimized project of the present utility model, left check valve body and right check valve body inside symmetrically structure, left check valve body inside comprises locking plug screw, seal washer, flap, O RunddichtringO, flap is connected by spring with locking plug screw, seal washer is arranged on locking screw beyond the Great Wall, and O RunddichtringO is arranged in the plane of flap.
The utility model has positive effect: the structure of this novel use caliper type and claw; claw connects left check valve body and right check valve body protective conduit is unaffected when breaking; add on-the-spot Security; claw is arranged on limited ring simultaneously; do not affect the handling of material, also avoid the very little moment of operator's misoperation to break valve body easily, cause false alarm; structural design is simple, easy to use.
Accompanying drawing explanation
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail:
Fig. 1 is structural drawing of the present utility model.
Wherein: 1, left check valve body, 2, locking plug screw, 3, seal washer, 4, flap, 5, O RunddichtringO, 6, snap ring, 7, locating stud, 8, limited ring, 9, claw, 10, right check valve body, 11, spring, 12, O type circle.
Embodiment
As shown in Figure 1, the utility model is urgent Pull breaking ualve, comprise left check valve body 1 and right check valve body 10, also comprise the snap ring 6 be sleeved on left check valve body 1, be sleeved on the limited ring 8 of left check valve body 1 root, claw 9 is evenly distributed on limited ring 8 by locating stud 7, and claw 9 one end is stuck on snap ring 6, and the other end is stuck on right check valve body 10.Wherein, the parts symmetrically structure of left check valve body 1 and right check valve body 10 inside, left check valve body 1 inside comprises locking plug screw 2, seal washer 3, flap 4, O RunddichtringO 5, flap 4 is connected by spring 11 with locking plug screw 2, seal washer 3 is arranged on locking plug screw 2, and O RunddichtringO 5 is arranged in the plane of flap 4.Also locking plug screw 2, seal washer 3, flap 4, O RunddichtringO 5 with left check valve body 1 internal structure symmetry is comprised in right check valve body 10.
Embodiment:
During use, claw 9 is evenly distributed on limited ring 8 by locating stud 7, be connected compacter in order to make left check valve body 1 with right check valve body 10, the number of claw 9 can be 3 or more, left check valve body 1 and right check valve body 10 utilize O type circle 12 to seal, then first the root cover of limited ring 8 from left check valve body 1 is entered, and then snap ring 6 cover is entered, claw 9 is taken off the junction surface on right check valve body 10, pound with a hammer, snap ring 6 is stuck in the bottom of claw 9, left check valve body 1 is connected with right check valve body 10.On snap ring 6, wire digging line is installed simultaneously.This valve is arranged on after on pipeline; as urgency, such as tank car surprisingly slips car, and such wire digging line oppositely pulls snap ring 6; after snap ring 6 bears default pulling force; snap ring 6 is thrown off claw 9 simultaneously and is come off, and left like this check valve body 1 is separated with right check valve body 10, simultaneously under the effect of spring 11; flap 4 with valve seal together; make left and right valve body each self-enclosed, so just protect pipeline and exempt from destruction, cause damage.
Above-described specific embodiment; the purpose of this utility model, technological scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
