Description of the drawings
Fig. 1 is the sectional view that the utility model automatically cuts off shuttle valve.
Specific embodiment
The embodiment of the utility model is further illustrated below in conjunction with attached drawing.
Refer to shown in attached drawing 1, one kind automatically cuts off shuttle valve, including cut-out valve body 1, the first spring 2, second spring 3,
Reset button 4, shuttle valve main body 5, cut-out valve core 6, stop valve valve pocket 7 and sealing element 8；The adaptation set of stop valve valve pocket 7
The rear end of the cut-out valve body 1 is connected on, the cut-out valve core 6 is arranged on the cut-out valve body 1 and stop valve
In valve pocket 7；One end of first spring 2 is arranged in the cut-out valve body 1, positioned at the cut-out valve body 1
Rear portion, first spring 2 is arranged in the cut-out valve core 6, positioned at the forepart of the cut-out valve core 6；
The shuttle valve main body 5 is inserted in by the second spring 3 in the stop valve valve pocket 7, positioned at the stop valve
The top of spool 6, the upper end of the shuttle valve main body 5 are located at the outside of the cut-out valve body 1 and are pressed with the reset
Button 4 connects；The sealing element 8 is arranged on the inner wall of the stop valve valve pocket 7, positioned at the stop valve valve pocket 7
Front end makes the stop valve valve pocket 7 be tightly connected by the sealing element 8 and the cut-out valve body 1.
Cut-out valve body 1, the first spring 2, cut-out valve core 6, stop valve valve pocket 7 and the sealing element 8 is coaxially disposed.
Second spring 3, reset button 4 and the shuttle valve main body 5 is coaxially disposed.
The axial direction of the shuttle valve main body 5 is axially vertical with the cut-out valve body 1.
1 and first spring 2 of cut-out valve body, second spring 3, reset button 4, shuttle valve main body 5, cut-out valve core
6th, stop valve valve pocket 7 is made of Stainless steel 316 material.It cuts off valve body 1 directly and media contact, bears pressure medium and corruption
Erosion, material therefor must reach mechanical property and good hot and cold processing work under defined medium temperature and pressure effect
Skill.In view of the utility model is mounted on before the instrumentations such as pressure guiding pipe, and mostly inflammable and explosive and Korrosionsmedium, therefore
It is whole preferably to use stainless steel.
First spring 2, second spring 3 are to automatically cut off the vital part of shuttle valve, and the quality of big spring influences the close of valve
Sealing property and service life, the quality of little spring then influences overcurrent cut-out performance, and the quality of the first spring 2, second spring 3 is very
The material of spring is depended in big degree.The quick action emergency valve spring material of relative adaptation is 1Cr18Ni9 class austenite stainless
Steel as long as processing is proper, had not only been resistant to the corrosion of natural gas, but also can guarantee the first spring 2, the quality of second spring 3.
The sealing element 8 is set for " O " shape structure and along the edge of the stop valve valve pocket 7.
The sealing element 8 is made of fluorubber material.Since the utility model is used for the device of gas medium,
The corrosion and erosion of the necessary resistance to natural gas of seal face materials.Further, since the sealing force of such valve be mainly pressure medium and
Spring force can not add very big sealing force, so sealing pair selects fluorubber material.
In use, when automatically cutting off shuttle valve and filling medium, reset button 4 is pressed, reset button 4 promotes shuttle valve main body 5, makes
Upstream medium enters 1 downstream of cut-out valve body by shuttle valve main body 5.After downstream pressure foundation, upstream and downstream pressure difference can not overcome
The spring force of first spring 2 promotes cut-out valve core 6 to move forward, and maintenance automatically cuts off shuttle valve opening state, automatically cuts off shuttle valve and beats
It opens, unclamps reset button 4 at this time.If automatically cutting off, pipeline breaking occurs for shuttle valve downstream or cutting ferrule collapses the abnormal conditions such as de-, is situated between
When matter big flow is released, since downstream pressure reduces, check valve both sides pressure difference overcomes spring force, and cut-out valve core 6 is vacillated downwards
Dynamic, cut-out valve core 6 is bonded with stop valve valve pocket 7, and cut-out valve body 1 turns off, and flow is prevented to continue to release.It treats at downstream problems
After reason, reset button 4 is pressed, medium flows into 6 downstream of cut-out valve core by shuttle valve main body 5, reduces by 6 liang of valve core of cut-out
Side pressure is poor, opens cut-out valve body 1, it is unimpeded to recover stop valve pipeline.
In conclusion the utility model has preferable corrosion resistance, sealing performance, intensity is high, can occur in downstream
Pipeline breaking or cutting ferrule collapse it is de- cut off valve body in time when abnormal conditions, medium large flow are released, mounted on natural gas facility
It is upper safer.
The above is only the preferred embodiment of the present invention, and it does not limit the scope of the patent of the present invention,
Every equivalent structure transformation made using the utility model description is directly or indirectly related with other are attached to
The technical field of product, is equally included in the patent within the scope of the utility model.
