A kind of disposable valve body of Contiuum type
Technical field
The utility model is related to a kind of disposable valve body of Contiuum type.
Background technology
During the use of some articles only have disposable using effect, such as fire extinguisher, medicine gas-liquid bottle or
Refrigerant cylinder etc., these training equipments are all disposably to be filled, and can not repeatedly be filled and used, this be in order to
Avoid the reduction for filling the process for using and causing valve seal effect repeatedly, use of the influence user to equipment.
And disclosed number of patent application " 95216157.5 ", patent name " to the disposable valve of cryogen Packaging Bottle ", wherein
Including valve body, valve nozzle, valve element, valve rod and valve handle, user's precession valve handle makes valve rod top to core print, causes the horizontal bulge loop of core print
Cross positioning table level and enter into valve cavity and withstand on valve seal mouthful, reach the purpose of closing;But also have the following problems:1、
User should be noted not so can not to cause just to be allowed when not filling and putting core by the rotation of valve handle exertin when filling first
Head horizontal ledge is crossed positioning step and is entered on valve seal mouthful, is unfavorable for the use of user;2nd, user is filling
After the completion of, although know that be sealed in core print on valve seal mouthful by turn valve handle, but if user does not screw valve handle and holds very much yet
Easily there is the core print situation not good to the sealing effectiveness of valve seal mouthful, leakage problems can be produced;3rd, core print integrally selects rubber
Material or other special plastics also greatly improve the use cost of user.

The top side of bar 3 is provided with external screw thread 35, the valve pocket 32 and is provided with spring 13, and the lower end of spring 13 is provided with valve head 2, institute
Stating valve head 2 includes plug 21 and blocked shot 22, and the outside of plug 21 is provided with rubber ring 23, and the center of blocked shot 22 is provided with through hole 221,
The bearing pin 4 is located at swing handle 31 and the upper table of valve body 1 through the pin-and-hole 33 of valve rod 3 and the through hole 221 of blocked shot 22, the limiting card 5
Between face.
The air inlet 11 runs through valve body 1, and the right surface of valve body 1 is run through in gas outlet 12, and air inlet 11 is connected with gas outlet 12
It is logical, allow user to be filled with material and discharged from gas outlet 12 from the entrance of air inlet 11.
The top of the valve body 1 is provided between thread cavity 15, and the thread cavity 15 of valve body 1 and the external screw thread 35 of valve rod 3 and leads to
Cross screw thread engagement connection so that valve rod 3 can be connected with valve body 1, and can allow user that valve rod 3 is screwed into valve body 1
Inside, so as to make valve head 2 bonded to each other with air inlet 11.
The outside of the valve rod 3 is provided with more than two grooves 34, and the inside of each groove 34 is both provided with sealing ring 14,
And mutual interference fit is provided between the valve rod 3 of sealing ring 14 and valve body 1, the setting of the inner seal rings 14 of groove 34 can have
Sealing effectiveness of the raising valve rod 3 of effect to valve body 1, it is to avoid leakage problems occurs in valve body 1.
The lower end of the limiting card 5 is provided with buckle(Do not mark), the upper surface of valve body 1 is provided with draw-in groove(Do not mark),
And the connection that cooperated between buckle and draw-in groove so that buckle can allow limiting card 5 to coordinate and be fixed on valve body 1 with the cooperation of draw-in groove
Top, and valve rod 3 can be carried out by limited support by swing handle 31.
The blocked shot 22 is rectangular structure, and the valve pocket 32 inside valve rod 3 is also square structure, and blocked shot 22 and valve pocket 32
Between mutually gap coordinate, be easy to user that blocked shot 22 is placed on the inside of valve pocket 32, be also convenient for user by bearing pin 4
The pin-and-hole 33 on through hole 221 and valve rod 3 on blocked shot 22.
The disposable valve body of the Contiuum type can allow user to be sealed the air inlet 11 of valve body 1, be easy to user to enter
Row is disposably filled;Wherein user carries out filling treatment by the air inlet 11 of valve body 1 and gas outlet 12, when filling completion
Afterwards, user takes apart limiting card 5 from the top of valve body 1, and then turn swing handle 31, valve rod 3 is screwed into inside valve body 1,
Until valve head 2 fits with the inside air inlet 11 of valve body 1;Again during turn swing handle 31, valve rod 3 continues to rotate down but valve head 2
Withstand on air inlet 11, so that connection valve rod 3 is broken with the bearing pin 4 of valve head 2, be easy to user to confirm that valve head 2 is tight
It is close to be sealed in the top of air inlet 11, it is to avoid what person the tight seal of valve head 2 cannot occur by fortuitous event on air inlet 1
Leakage problems;Wherein the air inlet 11 of valve body 1 runs through the upper and lower surface of valve body 1, and valve rod 3 closes at the upper opening of valve body 1, and
The upper end of valve body 1 is carried out by encapsulation process by the sealing ring 14 in valve rod 3 and the outside groove 34 of valve rod 3, it is to avoid from air inlet 11
What is entered fills material directly by the discharge of the top of valve body 1;And the pin-and-hole 33 of the outer surface of valve rod 3 is located at the lower section of groove 34, valve
The external screw thread 35 in the outside of bar 3 is located at the top of groove 34, even more avoids filling the possibility that leakage occurs in material;And the lower end of valve head 2
Plug 21 be inverted cone-shaped structure, the opening of the upper end of 1 inside air inlet of valve body 11 is also inverted cone-shaped structure so that the lower end of valve head 2
Plug 21 can snap onto air inlet 11, and the plug 21 on valve head 2 is squeezed into air inlet 11 by spring 13, increase
Sealing effectiveness of the valve head 2 to air inlet 11;Wherein valve body 1 is metal material, and valve rod 3 is plastic material or metal material with valve head 2
Matter, after valve rod 3 combines installation 1 inside of inlet valve body with valve head 2, the producer can pass through necking die by the open top of valve body 1
Carry out necking forming so that the maximum gauge of the opening diameter less than the external screw thread 35 of valve rod 3 at the top of valve body 1, it is to avoid valve rod 3 is screwed out
Valve body 1, prevents other people from carrying out repeated charging.
The beneficial effects of the utility model are:The disposable valve body of the Contiuum type have structure, it is simple easy to use the characteristics of;
Because limiting card is located between swing handle and valve body upper surface so that limiting card effectively can be carried out valve rod by swing handle spacing
Support, it is to avoid valve head is sealed in air inlet top because of fortuitous event turn swing handle when user is filled, greatly
Facilitate the ease of use of user;And through hole of the bearing pin on pin-and-hole and the plug of valve rod, allow the bearing pin can be by valve head
Blocked shot be connected in valve pocket, it is to avoid valve head Automatic-falling is sealed in the situation on air inlet, improves the use of user
, when being sealed to air inlet, can be sealed in valve head on air inlet by effect, and excessively rotary valve rod breaks bearing pin, so that
Allow user to confirm that valve head is sealed on air inlet, improve user and pass through sealing effectiveness of the valve head to air inlet, and in valve pocket
The setting of portion's spring is more the increase in sealing effectiveness of the valve head to air inlet, it is to avoid the problem of seepage occurs in valve body air inlet;And
The setting of valve head outer rubber circle can be good at for air inlet carrying out encapsulation process, it is to avoid valve head integrally uses rubber or spy
The cost of different plastics wastes problem, effectively reduces the use production cost of the device.
