Description
Technical field
The utility model relates to a kind of valve, and particularly a kind of aluminium membrane type one-way valve is applicable to the pharmacy jar of fire-protection equipment.
Background technique
As everyone knows, in many fire-protection equipments, be provided with pharmacy jar, such as dry powder medicinal cupping etc., in the fire-fighting process, medicament is under pressure through unidirectional ejection.But in most times, medicament need seal preservation, with the extended period life time.Existing pharmacy jar is to rely on rubber seal to seal with one-way valve mostly, but after long-time the placement, rubber seal is aging, causes poor sealing easily, and the feasible medicament of storing makes moist easily and causes losing efficacy.
Summary of the invention
The purpose of the utility model is to provide a kind of aluminium membrane type one-way valve, is applicable to the pharmacy jar of fire-protection equipment, can prevent effectively that the medicament of storing from causing because of making moist losing efficacy.
In order to achieve the above object, the utility model adopts following technological scheme to be achieved.
A kind of aluminium membrane type one-way valve comprises valve body and spool, it is characterized in that; Said valve body is a column; Offer the outlet passage that diameter reduces successively, the center-aisle and the inlet channel of ccontaining spool along the valve body central axis, said spool is provided with abradant surface near an end of inlet channel, is sealed and matched with the joint of center-aisle and inlet channel; The joint of said outlet passage and center-aisle is disposed with spool support, sealing aluminium foil diaphragm and gland nut; Said spool is provided with core bar near an end of outlet passage, is set with helical spring on the core bar, and said core bar slides and runs through the middle endoporus of spool support.
The characteristics of the utility model are with further improving:
Said gland nut is on the sealing aluminium foil diaphragm that is pressed in said spool support top.
Said sealing aluminium foil diaphragm is provided with impression.
Said spool is the conical surface near the abradant surface of an end of inlet channel; The said conical surface is provided with seal groove, is placed with seal ring in the seal groove.
In the aluminium membrane type one-way valve of the utility model; Valve body is a column; Offer the outlet passage that diameter reduces successively, the center-aisle and the inlet channel of ccontaining spool along the valve body central axis, said spool is provided with abradant surface near an end of inlet channel, is sealed and matched with the joint of center-aisle and inlet channel; The joint of said outlet passage and center-aisle is disposed with spool support, sealing aluminium foil diaphragm and gland nut; Said spool is provided with core bar near an end of outlet passage, is set with helical spring on the core bar, and said core bar slides and runs through the middle endoporus of spool support.Rely on helical spring pressure, spool is sealed and matched near the abradant surface of an end of inlet channel and the joint of center-aisle and inlet channel, realizes closing automatically of one-way valve; The joint of outlet passage and center-aisle is provided with sealing aluminium foil diaphragm, further realizes the isolated of valve body two ends.
The aluminium membrane type one-way valve of the utility model is used for the pharmacy jar of fire-protection equipment, can prevent effectively that the medicament of storing from causing because of making moist losing efficacy.During use, pharmacy jar relies on the spool of the force aluminium membrane type one-way valve of extraneous gas, makes extraneous gas get into center-aisle, and then gas passes the spool support, will seal the aluminium foil diaphragm and break through, thereby the formation medicament spurts path.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
Fig. 1 is the structural representation of a kind of diaphragm type one-way valve of the utility model;
Among the figure: 1, valve body; 101, outlet passage; 102, center-aisle; 103, inlet channel; 2, gland nut; 3, sealing aluminium foil diaphragm; 4, spool support; 5, helical spring; 6, spool; 601, abradant surface; 602, core bar; 7, seal ring.
Embodiment
With reference to Fig. 1, be a kind of aluminium membrane type one-way valve of the utility model.Wherein, valve body 1 is a column, offers the outlet passage 101 that diameter reduces successively, the center-aisle 102 and the inlet channel 103 of ccontaining spool 6 along valve body 1 central axis.Spool 6 is provided with abradant surface 601 near an end of inlet channel 103, and abradant surface is the conical surface, and the conical surface is provided with seal groove, is placed with seal ring 7 in the seal groove; Simultaneously, with the joint of center-aisle 102 and inlet channel 103 be taper, awl mouthful is sealed and matched with the abradant surface of spool 6.
Spool 6 is provided with core bar 602 near an end of outlet passage 101, is set with helical spring 5 on the core bar 602, and helical spring 5 is against spool support 4, and core bar 602 slides and is through the spool carriage center.Gland nut 2 is connected with outlet passage 101 inner threads.
The joint of outlet passage 101 and center-aisle 102 is provided with sealing aluminium foil diaphragm 3.Be specially: the joint looping step of outlet passage 101 and center-aisle 102, place spool support 4 on the ring-shaped step, place sealing aluminium foil diaphragm 3 on the spool support 4, gland nut 2 compresses seal membrane 3.Sealing aluminium foil diaphragm 3 is provided with impression, and sealing aluminium foil diaphragm 3 wears out during convenient the use.
Normally close under the situation, rely on the pressure of helical spring 5, spool 6 is sealed and matched near the abradant surface of an end of inlet channel 103 and the joint of center-aisle 102 and inlet channel 103, realizes closing automatically of one-way valve; The joint of outlet passage 101 and center-aisle 102 is provided with sealing aluminium foil diaphragm 3, further realizes the isolated of valve body 1 two ends.During unlatching, rely on the external gas pressure to promote the spool 6 of one-way valve, make extraneous gas get into center-aisle 102, and then gas passes the hole on the spool support 4, will seal the aluminium foil diaphragm and break through, thereby the formation medicament spurts path.
Although more than combine accompanying drawing that the embodiment of the utility model is described, the utility model is not limited to above-mentioned specific embodiments and applications field, and above-mentioned specific embodiments only is schematic, guiding, rather than restrictive.Those of ordinary skill in the art under the situation that does not break away from the scope that the utility model claim protected, can also make a variety of forms under the enlightenment of this specification, these all belong to the row of the present invention's protection.
