Abstract
The utility model provides a valve, particularly a low-temp. bellows valve for ships. The low-temp. bellows valve for ships is composed of a valve body 1, a valve cap 12 which is fixedly connected with the valve body 1, a guide body 15 which is fixed between the valve body 1 and the valve cap 12, a valve head 6 which can axially move in the guide body 15, a valve rod 14 which is screwed with the valve head 6, and a hand wheel 9 which is connected with the valve rod 14. The low-temp. bellows valve for ships is characterized in that bellows 17 are connected between the guide body 15 and the valve head 6. The low-temp. bellows valve for ships has the advantage that working media in a refrigeration system are not leaked and has the advantage of favorable sealing performance.
Description
The utility model relates to a kind of valve, especially a kind of low temperature Bellows valve peculiar to vessel.
Development along with deep-sea fishing, the raising of living standards of the people, the fresh-keeping degree that fish is obtained thing also more and more has higher requirement, fish is obtained the thing core temperature that freezes and requires to reach-50 ℃ on the present all kinds of fishing boat, be that evaporating temperature is-60 ℃～-70 ℃, therefore there is the problem that cryogen leaks outside and infiltrates that how to prevent, be the refrigeration plant of working medium with ammonia particularly, leaking outside of cryogen also will be caused the pollution of food, influences operator's health, employed stop valve in the refrigeration system, the sealing means of throttle valve can only alleviate leaking outside of cryogen for to fill out the letter sealing material in valve body, can not fundamentally solve, and it is short working life to fill out the letter sealing material, and effect is not ideal enough.
The purpose of this utility model provides a kind of good seal, the low temperature Bellows valve peculiar to vessel that no cryogen leaks outside.
Technical solution of the present utility model is: a kind of low temperature Bellows valve peculiar to vessel, by valve body 1, and the valve gap 12 that is fixedly connected of valve body 1, be fixed on guide way 15 between valve body 1 and the valve gap 12, can axially movable valve head 6 in guide way 15, the handwheel 9 that joins with the valve rod 14 of valve head 6 scyewed joint, with valve rod 14 forms, it is characterized in that: be connected to bellows 17 between guide way 15 and the valve head 6.
Described valve head 6 joins with following valve head 3, also is fixed with seal ring 2 between valve head 6 and the following valve 3.
The utility model compared with prior art, owing to be connected to bellows between guide way and valve head, and the bellows upper and lower end is respectively welding, so bellows seals the working medium in the refrigeration system, unlikelyly leak outside, solved the deficiency of valve in refrigeration plant from the valve rod place.
Fig. 1 is the utility model embodiment's a sectional view.
Below in conjunction with drawings and Examples the utility model is described further:
As shown in Figure 1: valve body 1, valve gap 12 are Cast Steel, guide way 15 top edge are fixed between valve body 1 and the valve gap 12, with bolt 8, nut 7 valve gap 12 is fixed on the valve body 1, guide way 15 top edge be respectively equipped with sealing gasket 13 up and down, the bottom of guide way 15 is fixed with locating stud 16, the set axially strong groove in locating stud 16 and the top of the valve head 6 that is positioned at guide way 15 inside matches, and valve head 6 can only be moved axially.The outside thread of the internal thread of valve head 6 and valve rod 14 lower ends matches, and valve rod 14 is provided with boss 18, and boss 18 is between valve gap 12 and guide way 15, to prevent that valve rod 14 from moving axially, handwheel 9 is equipped with in valve rod 14 upper ends, and nut 11, packing ring 10 match with valve rod 14, prevent that handwheel 9 from coming off.Select for use with 1cr18Ni9Ti is material, thickness is that the corrugated stainless steel tubing of 0.3mm is as Sealing, the upper end of bellows 17 and guide way 14 welding, lower end and valve head 6 welding, when rotation hand wheel 9 rotation valve rods 14,6 of valve heads move axially, bellows 17 with valve head 6 move axially and axial stretching, since bellows 17 is installed, working medium in the system and valve rod 14 is isolated, solved the problem that working medium leaks outside in the system.Close performance preferably for valve is had, be fixed with valve head 3 down in the lower end of valve head 6 with screw 5, packing ring 4, accompany seal ring 2 between valve head 6 and the following valve head 3, the material of seal ring 2 is a rubber, has the good performance of closing during with the assurance valve closing.
