Abstract

The utility model discloses an opening valve of a gas range, which adopts a fully closed structure, and solves the problem of easy leakage existing on the existing opening valve of a gas range in use caused by the adoption of an open structure. The utility model is mainly characterized in that the fully closed structure is composed of a valve body, a cover with a gas outlet hole, a valve plate, a valve core, a spring, a fastening nut, a gas inlet hole, a gas outlet hole, a key slot and a sealing ring. Therefore, the utility model can effectively prevent gas leakage, prolongs the service life of the opening valve, and improves the application safety of gas ranges.

Description

A kind of gas range open valve

The utility model relates to a kind of opening device that is installed on the gas range.

What existing gas range open valve adopted all is the Open architecture of spool, spring, spool and valve housing are fitted, have air inlet on the valve body, have air admission hole with the corresponding place of air inlet on the spool, rotational valve core can make this air admission hole communicate with air inlet or cut off, the end of spool has one to several ventholes, venthole communicates with air admission hole at valve core inside, spool is pushed down by spring, adopts the open valve of this structure in use to have the problem of following several respects: 1, cause easily causing when gas pressure raises in the open valve gas leakage when pressure-reducing valve is malfunctioning; 2, after open valve used a period of time, spool and valve body inner casing had wearing and tearing in various degree, caused gas leakage; 3, aging, the also easily generation gas leakage of coefficient of elasticity reduction of spring.

The purpose of this utility model is the problems referred to above of existing at existing gas range open valve to provide a kind of gas range open valve that adopts full-closed structure, fundamentally solved the problem of the easy gas leakage that the gas range open valve in use exists.

The technical solution of the utility model is achieved in that a kind of full-closed structure gas range open valve, by valve body, the port lid of giving vent to anger, spool, valve block, spring, fastening nut, sealing ring, compositions such as keyway, valve body is a hollow structure, one end and the port lid Joint of giving vent to anger, the junction is equipped with sealing ring and is prevented gas leakage, valve body is equipped with spool in the chamber, spool one end is connected by keyway with valve block, and by be contained in spring on spool one end with the valve block roof pressure on the port lid inner face of giving vent to anger, venthole covers and has one to several ventholes, the spool other end stretches out valve core and is screwed on the other end of valve body by the spiro cap of hollow, sealing ring is housed between nut and valve body end face prevents to become flat.During use, rotational valve core, the drive valve block rotates on the port lid inner face of giving vent to anger opens or closes venthole, thus the purpose that reaches air feed and turn-off source of the gas.

The utility model is owing to adopt above-mentioned full-closed structure, thereby can prevent gas leak phenomenon effectively, and prolonged the service life of open valve simultaneously, improved the security that gas range uses.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is air-vent cap end face and a valve block schematic diagram among the embodiment.

Below in conjunction with accompanying drawing, specific embodiments of the present utility model is done one describe in detail.

1 is valve body among the figure, 2 are the port lid of giving vent to anger, both connect by screw, prevent gas leakage by sealing ring 7 sealings between end face, spool 4 is the garden cylindricality for two ends, the centre is the structure of garden platform shape, the one end links to each other with valve block 3 by keyway 11, and by be contained in spring 5 on the spool 4 with valve block 3 roof pressures on port lid 2 inner faces of giving vent to anger, give vent to anger and be evenly equipped with three ventholes 10 on the port lid 2, valve block 3 is the plum blossom shape, has an air admission hole 9 on valve body 4 sides, and spool 4 other ends and valve body 1 inner surface are fitted, fastening nut 6 tightly overlaps and is screwed on valve body 1 other end, and is sealed by packing ring 8.During use, rotational valve core 4 drives valve block 3 and rotates, thereby opens or cover three ventholes 10 on the port lid inner face of giving vent to anger, thereby reaches the effect of gas range open and close.

Claims (2)

1, a kind of gas range open valve, it is characterized in that by valve body 1, the port lid 2 of giving vent to anger, valve block 3, spool 4, spring 5, fastening nut 6, air admission hole 9, venthole 10, packing ring 7,8 and keyway 11 form, wherein valve body 1 is a hollow structure, one end and port lid 2 Joints of giving vent to anger, seal washer 7 is equipped with in the junction, valve body is equipped with spool 4 in 1 chamber, spool 4 one ends are connected by keyway 11 with valve block 3, and by be contained in spring 5 on spool 4 one ends with valve block 3 roof pressures on port lid 2 inner faces of giving vent to anger, give vent to anger and have venthole 10 on the port lid 2, spool 4 other ends stretch out valve core 1 and are screwed on the other end of valve body 1 by nut 6 cover of hollow, between nut 6 and valve body 1 end face sealing ring 8 is housed, air admission hole 9 is directly processed on valve body 1.
