Embodiment
The invention will be further described with the following Examples.
Refer to a kind of novel clamp claw Pull breaking ualve as Figure 1-3, including the first valve body 1, the first valve element 2, second
The valve element 4 of valve body 3 and second, the first valve body 1 and the second valve body 3 being mutually interlocked is connected by the ring flange 5 at two ends with fluid line
Connect.The outer end of first valve body 1 and the second valve body 2 is respectively and fixedly provided with positioning disk 6, and the first valve element 2 and the second valve element 3 are close to positioning disk 6
Side offer compression spring 8 be placed with spring groove 7, spring groove 7, passed through and the first valve element 2 or the second in compression spring 8
The affixed locating dowel 9 of valve element 4, and locating dowel 9 passes through the positioning hole 10 on positioning disk 6.The setting of locating dowel 9 and positioning hole causes
Valve element can be moved when acting along the axis direction of valve body, and medium cut-out is relatively reliable.
There is on claw spring holder 11, the second valve body 3 of the top of claw spring holder 11 by multiple interior projection on second valve body 3
Hex screw 12 is fixed with claw fixed disk 13.Claw 19 is provided with 8 altogether, and claw spring holder is stretched into the lower end of each claw 19
In sleeve 14 on 11, and it is affixed with the spring holder 15 that is placed in sleeve 14, and the bearing pin 16 of spring holder 15 stretches into card
In latch spring 17, the termination 18 of spring holder 15 presses on one end (referring to Fig. 4) of claw spring 17, the upper end of claw 19
Through claw fixed disk 13 and it is sticked at the first valve body 1 and the fastening of the second valve body 3 in the groove 18 of both sides.The He of first valve element 2
Second valve element 4, which has, to be used to block the central raised of fluid, it is central raised on be provided with the first O-ring seal 20.
As further preferred scheme, described one end of compression spring 8 presses on the surface of positioning disk 6, and the other end is compressed
In the bottom wall of spring groove 7.
As further preferred scheme, the positioning disk 6 is fixed on the first valve body 1 or the second valve by jump ring circle 21
On body 3.
It is solid by hex screw 22 on the first valve body 1 and the second valve body 3 referring to Fig. 2 as further preferred scheme
It is connected to hangers 23.
As further preferred scheme, sealed at the first valve body 1 and the fastening of the second valve body 3 by the second O-ring seal
24。
As further preferred scheme, the steel wire diameter of the claw spring 17 is 1.4mm, then pull-off force threshold values is by original
The 1400Kg come is reduced to 600Kg, can more effectively protect pipeline.
Its specific operation principle of the Pull breaking ualve is：Pull breaking ualve during normal condition is as shown in figure 1, keep medium stream in valve
It is logical；When the pipeline being connected with Pull breaking ualve is pullled and pull-off force exceedes threshold values, as shown in figure 5, the first valve body 1 and the second valve body
The elastic force for overcoming the clamping force and claw spring 17 of the upper end of claw 19 to put on claw 19 between 3 is forced to separate, the
One valve element 2 and the second valve element 4 are ejected under the elastic force of compression spring 8 causes Pull breaking ualve to close.
During two valve bodies are separated, claw spring 17 is compressed by the lower end of claw 19, and spring holder 15 is set
Put so that claw 19 is relatively reliable when acting, and termination 18 also increases the contact area with claw spring 17.
In addition, claw fixed disk 13 is to be fixed in by soket head cap screw 12 on valve body, by conventional monolithic construction
Split-type structural is changed into, is easier to operate to when being resetted after Pull breaking ualve disengagement, reduces time and the work difficulty of reset.By
In in operation is actually resetted, the first valve body 1 and the second valve body 3 are connected on fluid line, are not ensured that such as theory
In ideal situation, it is difficult to ensure that the first valve body 1 and the second valve body 3 are vertically aligned completely, so certain deflection will be produced
Angle, has certain deflection angle to reset in the case of without alignment pin, but must align ability if any alignment pin
Reset successfully.Specifically, as shown in fig. 6, existing Pull breaking ualve is monoblock type, after Pull breaking ualve disengagement, it is necessary to first by bullet
It could be resetted in the alignment locating groove of spring alignment pin 15, the first valve body 1 and the second valve body 3 can not have any deflection angle, slightly
There is deflection angle can not just complete reset, difficulty is brought to work is resetted.Referring again to Fig. 6, when resetting, by claw fixed disk
On 12 screw in compressions so that 12 claws open completely, then connect two ends with two M8 screw rods, tighten up on two end screw rods
Nut is until reset completely, then unclamps 12 screws on claw fixed disk, pull down two connecting screw rods, entirely reset work
Terminate.
And jack catchs type Pull breaking ualve of the present invention, as shown in fig. 7, after Pull breaking ualve is disengaged, due to claw fixed disk 13
It is split type, when resetting, the spring holder 15 on claw fixed disk 13 is not limited by claw fixed disk 13, i.e. spring
Alignment pin 15 can not be resided at first on claw fixed disk 13, can be resetted in the case of certain deflection angle, multiple
Spring holder 15 is fixed in soket head cap screw 12 effect that monoblock type is can reach on claw fixed disk 13 behind position.Exist
During reset, by 8 screw in compressions on claw fixed disk 13 so that 8 claws open completely, then with two M8 screw rods two are connected
End, tightens up the nut on two end screw rods until reset completely, then unclamps 8 screws on claw fixed disk 13；Again will positioning
Pin is connected on claw fixed disk with soket head cap screw and can reach monoblock type effect, pulls down two connecting screw rods, whole to reset
End-of-job.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than to present invention guarantor
The limitation of scope is protected, although being explained with reference to preferred embodiment to the present invention, one of ordinary skill in the art should
Work as understanding, technical scheme can be modified or equivalent substitution, without departing from the reality of technical solution of the present invention
Matter and scope.
