Abstract
The utility model discloses a novel charging valve which comprises a valve body and a valve core, wherein the valve core comprises a valve core shaft and a sealed end part; a return spring is arranged in the valve body and arranged on the valve core shaft in a sleeving manner; the interior of the valve body comprises a sealed cavity and a valve cavity which are communicated with each other; the inner diameter of the valve cavity is larger than that of the sealed cavity; a positioning slot is formed in a position near the end part of the valve cavity; a positioning plate is arranged in the positioning slot; the first end part of the return spring is propped against the positioning plate; a seal ring is arranged on the outer ring surface of the sealed end part of the valve core; the outer diameter of the seal ring is matched with the sealed cavity of the valve body. According to the utility model, the charging valve is better in leak tightness, good in flow capacity, and low in manufacturing cost.
Description
Technical field
The utility model relates to a kind of valve arrangement, more particularly, relates to a kind of charge-filling valve charging for large-scale refrigerating system being carried out to large flow, rapid fluid.
Background technique
As everyone knows, from a container to another container, fill with in the process of liquid and conventionally need between two containers, arrange and charge passage, charging of using at present is all provided with the charge-filling valve that opens and closes pipeline conventionally in pipeline, thereby flow liquid is filled in another container (or system) from a container.
Charge-filling valve also claims check valve, most for being arranged on the loop that need charge fluid device, mainly plays and charge and check two effects in loop.And the following shortcoming of existing charge-filling valve ubiquity: the one, valve flow is generally lower; The 2nd, valve body is in charging using process, and its inner spring easily skew walks, and affects the performance that charges of valve.
Model utility content
Technical problem to be solved in the utility model is: provide that a kind of better tightness, negotiability are better, the novel charge-filling valve of double orientation protection.
For achieving the above object, the utility model is taked following technological scheme: a kind of novel charge-filling valve, comprise valve body, spool, described spool comprises spool axial region and hermetic terminal, in described valve body, is provided with Returnning spring, and described Returnning spring is enclosed within poppet shaft portion, the Seal cage, the valve pocket that in described valve body, comprise connection, the internal diameter of described valve pocket is greater than the internal diameter of Seal cage, and contiguous valve pocket end is provided with locating slot, in described locating slot, is provided with location piece; The first end of described Returnning spring is resisted against on described location piece; The hermetic terminal outer ring surface of described spool is provided with seal ring, and the external diameter of described seal ring and the Seal cage of described valve body are suitable.
On described hermetic terminal outer ring surface, seal groove is set, described seal ring is placed in seal groove.
The second end of described Returnning spring is resisted against on the spring fitting end face of spool axial region.
The hermetic terminal of described spool is provided with frustum, and the Seal cage of described valve body is provided with conical inboard wall, and described frustum and Seal cage conical inboard wall are suitable.
Described seal ring is O type circle, and described seal ring is made by rubber.
In the middle of described location piece, be provided with through hole, described location piece is provided with the angle of inside bending.
Described valve body is the pressure mouth of an inside constriction near the end of locating slot, and described pressure mouth is processed to form after location piece assembling.
The beneficial effects of the utility model are:
1) the utility model provides firm orientation type, occurs drift condition while preventing spring-compressed, and improves the secondary pressure mouthful of Security, and in the time of preventing from charging, spool flies out.
2) the utlity model has compact structure rationally, good seal performance, charge the advantages such as negotiability is large, with low cost.Substitute original low discharge, inefficient charge-filling valve completely, can reuse, play the double action that charges and detect.
Accompanying drawing explanation
Fig. 1 is charge-filling valve structure sectional view of the present utility model (charging state).
Fig. 2 is charge-filling valve structure sectional view of the present utility model (closed condition).
Embodiment
As shown in Figure 1, 2, the utility model charge-filling valve, comprise valve body 1, spool 2, described spool 2 comprises spool axial region 21 and hermetic terminal 22, is provided with Returnning spring 4 in described valve body, and described Returnning spring is enclosed within poppet shaft portion, the Seal cage 11, the valve pocket 12 that in described valve body, comprise connection, the internal diameter of valve pocket is greater than the internal diameter of Seal cage, and contiguous valve pocket end is provided with locating slot 13, is provided with location piece 5 in described locating slot; The first end 41 of described Returnning spring is resisted against on described location piece 5; Hermetic terminal 22 outer ring surfaces of described spool are provided with seal ring 3, and the external diameter of described seal ring 3 and the Seal cage of described valve body are suitable, thereby form sealing pair.
On the outer ring surface of described hermetic terminal 22, seal groove is set, described seal ring 3 is placed in seal groove.
The second end 42 of described Returnning spring is resisted against on the spring fitting end face 23 of spool axial region.
The hermetic terminal of described spool is provided with frustum 24, and the Seal cage of described valve body is provided with conical inboard wall, and described frustum and Seal cage conical inboard wall are suitable.
Described seal ring 3 is O type circles, and described seal ring is made by rubber.
Described location piece comprises the fixedly through hole 52 of ring body 51 and middle part circle, and on the fixedly ring body of location piece, is evenly provided with the angle 53 of three inside bendings, effectively prevents the play of Returnning spring.
After completing the assembling of Returnning spring and location piece, on the end at valve body 1 near locating slot 13, by inside extruding, form and press mouth 6, realize the secondary location of valve body location piece.
While charging, as shown in Figure 1, the top 25 of spool 2 is pushed by external force F, cause spring 4 compressions, spool 2 moves to the sealing pair direction that is opened, and at this moment valve seal chamber 11, valve pocket 12 and location piece manhole 52 form circulation passages, realize the object of fluid flashing.While closing, as shown in Figure 2, the top 25 of spool 2 is not pushed by external force, and under the active force of spring 4, spool 2 is closed direction to sealing pair and moves, and Seal cage 11 close contacts of O type circle 3 and valve body 1 are at this moment realized the object of the sealing after charging.
More than open is only specific embodiment of the utility model; do not form the restriction to the utility model protection domain; for the utility model person of an ordinary skill in the technical field; do not departing under general idea prerequisite of the present utility model; variation and the replacement without process creative work according to technical solutions of the utility model, done, within all should dropping on protection domain of the present utility model.
