Abstract
The utility model provides a two-purpose pressure limit valve of hand and automatic, which includes a shell, a cavum mounted in the shell, a first and a second entrance mounted in the shell, the axes of the first and the second entrance are being 90 degree. A guide pole is mounted in the cavum of the shell, and a spring is mounted on the guide pole. A spring fixing sleeve is mounted on an end of the guide pole which is towards the first entrance, a sliding sleeve is mounted on the other end of the guide pole. A ring pull is mounted through the shell outer end by the guide pole, and a sealing sleeve is mounted on the outer side of the spring fixing sleeve. The utility model has the advantages of: simple structure, comparatively low manufactureing cost, good security, good effection of pollution-discharging and sealability and so on.
Description
Technical field
The utility model relates to the stove and accessory accessory, is a kind of a kind of hand-operated and automatic pressure-limit valve that is mainly used on the stove and accessorys such as gas range or air heating stove.
Background technique
The pressure-limit valve that uses on the stoves such as existing gas range and air heating stove has multiple structure, and general working life is shorter, particularly in order to guarantee the Security of its use, needs often to change pressure-limit valve.There is some deficiency in the pressure-limit valve of existing various structures: complex structure, manufacture cost height; The adhesion of each parts surface of contact easily influences its performance after use a period of time, can not guarantee its Security; Filth-discharging effect is poor; Sealing effect is not good enough etc.
Summary of the invention
The purpose of this utility model provides a kind of hand-operated and automatic pressure-limit valve, makes it have simple in structure, advantage such as manufacture cost is relatively low, Security good, blowdown and good sealing effect.
The utility model is achieved through the following technical solutions for achieving the above object: a kind of hand-operated and automatic pressure-limit valve, comprise housing, offer cavity in the housing, housing is offered first port and second port, the axis of first port and second port is 90 °, guide pillar is installed in the cavity of housing, mounting spring on the guide pillar, end mounting spring fixed cover towards first port of guide pillar, the guide pillar the other end is installed flip sleeve, guide pillar passes place, housing outer end draw ring is installed, and stuffing box gland is installed in the spring retaining sleeve outside.The centre of stuffing box gland is a cavity, and upper wall, Zuo Bi and You Bi interconnect, and Zuo Bi bottom and You Bi bottom are respectively equipped with the sealing riglet that extends laterally.Housing divides upper shell and lower shell body, and upper shell and lower shell body adopt and be threaded.Between upper shell and the lower shell body connecting sleeve is installed, the connecting sleeve middle part is provided with boss.Connecting sleeve is provided with outside thread in the upper and lower of boss.Offer groove on the upper-end surface of flip sleeve.Offer through hole on the second port bottom surface, through hole is oval, and is opened in the top of port.
The utility model draws following advantage through repetition test: low cost of manufacture; Relieving characteristics is good, safe; Long service life; Blowdown and good seal performance; Can manually draw guide pillar to prevent the adhesion of component surface of contact, avoid making after the adhesion between the component pressure release function to reduce, and then avoid the generation etc. of explosive accident.
Description of drawings
Embodiment
Hand-operated and automatic pressure-limit valve of the present utility model, comprise housing, offer cavity in the housing, the axis that housing is offered first port 3 and second port, 15, the first ports 3 and second port 15 is 90 °, guide pillar 9 is installed in the cavity of housing, mounting spring 5 on the guide pillar 9, the end mounting spring fixed cover 4 towards first port 3 of guide pillar 9, and guide pillar 9 the other ends are installed flip sleeve 11, guide pillar 9 passes place, housing outer end draw ring 13 is installed, and stuffing box gland 2 is installed in spring retaining sleeve 4 outsides.The centre of stuffing box gland 2 is cavitys, and upper wall, Zuo Bi and You Bi interconnect, and Zuo Bi bottom and You Bi bottom are respectively equipped with the sealing riglet 18 that extends laterally.Housing divides upper shell 1 and lower shell body 8, and upper shell 1 and lower shell body 8 adopt and be threaded.Connecting sleeve 17 is installed between upper shell 1 and the lower shell body 8, and connecting sleeve 17 middle parts are provided with boss 19.Connecting sleeve 17 is provided with outside thread in the upper and lower of boss 19.Offer groove 20 on the upper-end surface of flip sleeve 11.Second port is offered through hole 16 on 15 bottom surfaces, and through hole 16 is oval, and is opened in the top of port 15.When the utility model uses, be installed on the bodies of heater such as gas range or air heating stove, when normally using, when pressure surpasses setting value, can realize releasing pressure automatically.Also draw ring 13 can be often spurred in the use, checking the travelling performance of guide pillar 9, and the surface of contact adhesion between the component can be avoided making.6 is seal rings among the figure, the 7th, and cavity, the 10th, lower shell body cavity, the 12nd, hole, the 14th, through hole.
