Abstract
The utility model relates to a liquid inflow device, in particular to an automatic liquid supplying valve of sodium borohydride, which is formed by a joint pipe, a joint bow, a sealing washer, a valve body, a side hole, a sealing bowl, a liquid passing hole, a rod head, a spring, a post rod, a liquid communicating hole, a spring fixed cylinder and a sealing ring. The spring fixed cylinder which is cylindrical and matched with the inner wall of the valve body through threads is arranged inside the lower end of the valve body; and the post rod is positioned in the spring fixed cylinder and movably matched with the spring fixed cylinder. The rod head is movably matched with the valve body. The spring is sleeved on the post rod and arranged between the rod head and the spring fixed cylinder. The sealing bowl which is connected with the post rod into a whole body is coaxial with the post rod, and has an upward opening is arranged at the lower end of the post rod and the sealing ring is adhered to the inside of the sealing bowl. Compared with the prior art, the utility model has stronger sealing property and the advantages of convenient operation.
Description
Technical field
The utility model relates to a kind of liquid inflow device, particularly relates to a kind of sodium borohydride automatic liquid supply valve.
Background technique
The patent No. is that 200820300918.8 model utility " the automatic inflow device of a kind of liquid " discloses and a kind ofly sodium borohydride can be imported to the reaction chamber that catalyzer is housed and be hydrolyzed, thus the valve of the feed fluid of preparation hydrogen.This scheme exists following defective:
Because the liquid supply valve in this scheme is to rely on described sealing gasket to play the effect of seal fluid with combining of valve interior wall, yet only rely on the elastic force of sealing gasket self pressure of the inwall of valve body to be difficult to keep out the pressure of liquid.And the spring in the device also only is the effect that resets of having played, and does not play the effect that strengthens sealing force.Therefore, in use, occur jolting, move, under inclination even the inverted situation, the liquid pressure value at liquid supply valve position has bigger fluctuation, and in this case, the elastic force of sealing gasket self is difficult to liquid is sealed fully.
The model utility content
The utility model provides a kind of effectively enclosed liquid for solving the deficiencies in the prior art, and the sodium borohydride automatic liquid supply valve that can conveniently open.
The scheme that solves the utility model technical problem is: sodium borohydride automatic liquid supply valve is made of adaptor tube, joint bowl, seal washer, valve body, side opening, seal bowl, liquid pass hole, bar head, spring, push rod, liquid-through hole, solid spring tube and seal ring.
Valve body is a cylindrical body, and all there is screw thread its outside, upper end and inboard, lower end.There is the solid spring tube of the inwall of columnar and a valve body with screw-thread fit the inside of valve body lower end, and liquid-through hole is two through holes longitudinally on the solid spring barrel.Push rod is in the solid spring tube and with solid spring tube and is in active relationship.The upper end of push rod is the discoidal bar head with two liquid pass holes, and the diameter of bar head is greater than the diameter of push rod, and the inwall of bar head and valve body is in active relationship.Spring be placed on the push rod and be in the bar head and solid spring tube between.The lower end of push rod is the seal bowl that the opening of and concentric as a whole with push rod makes progress, and the inside of seal bowl is bonded with seal ring.
The joint bowl is that Open Side Down and the inboard screwed bowl bodies in lower end, the joint bowl be placed in valve body the upper end and with valve body with screw-thread fit.Axle center with the as a whole adaptor tube penetrator bowl of joint bowl has side opening on the sidewall of adaptor tube lower end.The inside of joint bowl is bonded with the seal washer that rubber is made.
When being in idle state, under the elastic force effect of spring, seal bowl and seal ring are upwards spurred by push rod and combine closely with the lower end of valve body.Liquid is closed.
In the time of need getting liquid, only need clockwise direction swivel joint bowl, the lower end of adaptor tube with the bar head to pressing down, spring is compressed, leave the lower end of valve body when seal ring after, liquid flows in the valve body from the annulus between seal ring and the valve body, and flows into adaptor tube by side opening.
Adopt such scheme, can reach following effect:
1. because lower end and the seal ring of valve body is to combine closely mutually by the elastic force of spring, this utilizes rubber self elastic force to realize sealing to compare, have stronger reliability with traditional.
2. owing to only need the swivel joint bowl just can realize the switching of valve, it is very convenient to operate.

Fig. 2 is the A-A sectional drawing of Fig. 1.
Among the figure: 1. adaptor tube 2. joint bowls 3. seal washers 4. valve bodies 5. side openings 6. seal bowls 7. liquid pass holes 8. bar heads 9. springs 10. push rods 11. liquid-through holes 12. are consolidated spring tube 13. seal rings
Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Sodium borohydride automatic liquid supply valve is made of adaptor tube 1, joint bowl 2, seal washer 3, valve body 4, side opening 5, seal bowl 6, liquid pass hole 7, bar head 8, spring 9, push rod 10, liquid-through hole 11, solid spring tube 12 and seal ring 13.Valve body 4 is a cylindrical body, and all there is screw thread its outside, upper end and inboard, lower end.There is the solid spring tube 12 of the inwall of columnar and a valve body 4 with screw-thread fit the inside of valve body 4 lower ends, and liquid-through hole 11 is two through holes longitudinally on solid spring tube 12 walls.Push rod 10 is in the solid spring tube 12 and with solid spring tube 12 and is in active relationship.The upper end of push rod 10 is the discoidal bar heads 8 with two liquid pass holes 7, and the diameter of bar head 8 is greater than the diameter of push rod 10, and bar head 8 is in active relationship with the inwall of valve body 4.Spring 9 be placed on the push rod 10 and be in bar head 8 and solid spring tube 12 between.The lower end of push rod 10 is the seal bowls 6 that make progress with push rod 10 openings as a whole and concentric, and the inside of seal bowl 6 is bonded with seal ring 13.Joint bowl 2 is that Open Side Down and the inboard screwed bowl bodies in lower end, joint bowl 2 be placed in valve body 4 the upper end and with valve body 4 with screw-thread fit.Axle center with the as a whole adaptor tube 1 penetrator bowl 2 of joint bowl 2 has side opening 5 on the sidewall of adaptor tube 1 lower end.The inside of joint bowl 2 is bonded with the seal washer 3 that rubber is made.When being in idle state, under the elastic force effect of spring 9, seal bowl 6 and seal ring 13 are upwards spurred by push rod 10 and combine closely with the lower end of valve body 4.Liquid is closed.In the time of need getting liquid, only need clockwise direction swivel joint bowl 2, the lower end of adaptor tube 1 with bar head 8 to pressing down, spring 9 is compressed, leave the lower end of valve body 4 when seal ring 13 after, liquid flows in the valve body 4 from the annulus between seal ring 13 and the valve body 4, and flows into adaptor tube 1 by side opening 5.
