Abstract
The utility model discloses a semiclosed free-disassembly stop valve comprising a right angle-shaped valve body, channels communicated with each other forming in the valve body and a valve core in an upper part channel of the valve body. A lower part channel of the valve body is communicated with a connecting pipe; a valve inside is disposed in a right part channel of the valve body; an end part of the valve inside is provided with a valve cap; the left part of the valve body is provided with a thread; two seal rings are arranged between the valve core and the valve body; the valve cap sleeves the upper part of the valve body; a through hole matching with the top part of the valve core is formed on the valve cap; and the valve core extends out of the through hole of the valve cap. The through hole matching with the valve core is formed on the valve cap; an internal hexagonal wrench can be placed into the through hole without detachment of the valve cap, so an on-off state of the valve core can be adjusted; and the valve cap and the valve core are in cooperative seal, so a problem of secondary seal invalidity of valve cap detachment is avoided.
Description
Technical field
The utility model relates to a kind of apparatus of air conditioning and refrigeration system stop valve, is specifically related to a kind of semiclosed stop valve of exempting to tear open.
Background technique
Existing for freeze or the apparatus of air conditioning on stop valve, its inner spool turns clockwise by hexagon wrench and closes, is rotated counterclockwise and opens, valve body and spool mainly coordinate soft seal by an O type circle, outside installs a bonnet again additional.When operation of air conditioner, bonnet need be taken and opened apart spool, then bonnet be reinstalled and tightened.
Because O type circle is soft seal state, and pressure in air-conditioning system is up to 4.0MPa, and air-conditioning refrigerant used has stronger permeability, therefore can not reach hermetic effect, long-term seepage can cause larger impact to air-conditioning system, so mainly ensure sealing by the secondary seal of bonnet.
But air-conditioning due to installer's carelessness, does not often reinstall bonnet or tighten when mounted; Or due to the difference of air-conditioning Environmental Conditions, bonnet is also easy to lose, and causes heat pump performance bad.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of semiclosed stop valve of exempting to tear open, and it can solve poorly sealed leakage, the problem that bonnet secondary seal lost efficacy simultaneously of causing of O type circle on spool.
For solving the problems of the technologies described above, the technical solution that the utility model is semiclosed exempts to tear open stop valve is:
Comprise rectangular shape valve body, in valve body, form the passage communicating with each other; In the upper channel of valve body, be provided with spool, the lower passage of valve body is communicated with connecting tube; In the right part passage of valve body, be provided with valve inside, the end of valve inside is provided with valve cap; The left part of valve body is provided with screw thread; Two seals circle is set between described spool and valve body; The top of described valve body is arranged with bonnet; The top of bonnet offers the through hole coordinating with the top of spool, and described spool stretches out from the through hole of bonnet.
The auxiliary section of described spool and bonnet is inclined-plane.
Described seal ring is O type circle.
The technique effect that the utility model can reach is:
The utility model has increased the sealing surface between spool and valve body, can greatly reduce the leakage rate between spool and valve body.
The utility model has the through hole coordinating with spool on bonnet, can, in the situation that not dismantling bonnet, inner hexagon spanner be stretched into this through hole, thus the on off state of regulating spool; And can make bonnet and spool fitted seal, the problem of having avoided dismounting bonnet secondary seal to lose efficacy, simple, convenient.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the semiclosed schematic diagram of exempting to tear open stop valve of the utility model;
Fig. 2 is decomposing schematic representation of the present utility model.
Description of reference numerals in figure:
1 is bonnet, and 2 is O type circle,
3 is spool, and 4 is valve cap,
5 is valve inside, and 6 is valve body,
7 is nut, and 8 is connecting tube.
Embodiment
As shown in Figure 1 and Figure 2, the utility model is semiclosed exempts to tear open stop valve, comprises rectangular shape valve body 6, the passage that the interior formation of valve body 6 communicates with each other; In the upper channel of valve body 6, be provided with spool 3, the lower passage of valve body 6 is communicated with connecting tube 8; In the right part passage of valve body 6, be provided with valve inside 5, the end of valve inside 5 is provided with valve cap 4; The left part of valve body 6 is provided with screw thread, for attaching nut 7;
Twice O type circle 2 is set between spool 3 and valve body 6;
The top of valve body 6 is arranged with bonnet 1; The top of bonnet 1 offers the through hole coordinating with the top of spool 3, and spool 3 stretches out from the through hole of bonnet 1;
The utility model is applicable on refrigeration or the apparatus of air conditioning.
