Abstract
The utility model discloses a dual-target cassette type decompression valve and matching windpipe connecting component. The cassette type decompression valve comprises a valve body and an air-in nut and an air-out nozzle positioned on the valve body. The windpipe connecting component is composed of a tie-in connecting component and a windpipe tie-in which are joggled together and can be opposite; wherein, the tie-in connecting component is connected with the outside screw thread of the air-in nut; and the front end of the windpipe tie-in shows a shape of stair and inserts into an air intake which is at the middle of the air-in nut. The tie-in connecting component and the windpipe tie-in are sealed through two O-shaped sealing rings. The windpipe connecting component of the utility model can be easily connected with or disassembled from the air-in nut of the decompression valve body easily so that the decompression valve can not only use small capacity gas cylinders but also connect with large capacity steel air tanks, reaching two functions and a quite convenient use. Furthermore, the windpipe connecting component connecting with the valve body does not destroy the strength and appearance of the valve body, and a full use of the two O-shaped sealing rings in the air-in nut realizes double sealing and greatly improves the security and reliability of the utility model in use.
Description
Technical field:
The utility model relates to the gas appliance technical field, especially relates to a kind of cassette reduction valve.In addition, the utility model also relates to a kind of tracheae connection part.
Background technique:
At present, the cassette reduction valve overwhelming majority who uses on the small gas apparatus can only use disposable small capacity gas cylinder (200g-250g), and cost is higher, and burning is shorter service time, can not directly be connected but have, have the inconvenience part in the use with the big capacity steel cylinder gas tank of using always.And above-mentioned small capacity gas cylinder results in hand cramps to the Consumer being difficult to purchase on the market.For above-mentioned reasons, use the popularization of small gas apparatus on market of cassette reduction valve to be subjected to technical restriction.In order to address this problem, also have small part factory to connect a gas-tpe fitting recently and realize and being connected of capacity steel cylinder greatly, but in fact this kind method to have changed the complete structure of valve body, has reduced security of valve body by boring on body wall.Because the body wall wall thickness is little, mechanical strength is not enough, causes the join strength of gas-tpe fitting and reliability all lower, has potential risk of breakage and tightness problem.And gas-tpe fitting is non-dismountable, and the collision back is damaged the position that is connected with valve body easily, causes fatal problems such as gas leakage.In addition, said method is given the sensation of " purposely causing complication ", has destroyed the outward appearance of product.
The model utility content:
The purpose of this utility model be the deficiency that exists at prior art and provide a kind of new cassette reduction valve and with the matching used tracheae connection part of reduction valve, to solve the problem of two purposes, realize that safety connects.When only with this cassette reduction valve, can use bottled disposable small gas cylinder, and when this clamping valve and the supporting use of tracheae connection part, can realize that the cassette reduction valve is connected with the safety of big capacity steel cylinder gas tank.
For achieving the above object, cassette reduction valve of the present utility model comprises a valve body, wherein, air inlet nut middle part is provided with step-like suction port, the inside and outside two ends of suction port are respectively equipped with the O RunddichtringO, it also comprises a tracheae connection part, described tracheae connection part is by being fastened in together and relatively turnable joint link and gas-tpe fitting constitute, wherein, the joint link is threaded with air inlet nut outer end, the gas-tpe fitting front end is step-like, and inserts in the suction port at air inlet nut middle part, between the two by dual O RunddichtringO sealing.
By being fastened in and relatively turnable joint link and gas-tpe fitting constitute, wherein, form internal thread on the inwall of joint link with the matching used tracheae connection part of cassette reduction valve, it is step-like that the gas-tpe fitting front end then is.
The beneficial effects of the utility model are: the tracheae connection part can be easily links to each other with air inlet nut on the valve body or dismantles, thereby makes reduction valve both can use the small capacity gas cylinder, can connect big capacity steel cylinder gas tank again, reaches dual-purpose effect, and is very easy to use.In addition, the tracheae connection part links to each other with valve body and does not destroy body strength and outward appearance, and makes full use of two O RunddichtringOs in the air inlet nut suction port, realizes double seal, has improved Security and the reliability used greatly.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Accompanying drawing 1 is the structural representation of tracheae connection part of the present utility model;
Accompanying drawing 2 is one of user mode figure of cassette reduction valve of the present utility model
Accompanying drawing 3 be cassette reduction valve of the present utility model user mode figure two
Embodiment:
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
See shown in accompanying drawing 2 and the accompanying drawing 3: reduction valve of the present utility model comprises a valve body 10, valve body 10 is provided with air inlet nut 11 and outgassing nozzle 12, wherein, air inlet nut 11 middle parts are provided with step-like suction port 111, suction port 111 inside and outside two ends are respectively equipped with O RunddichtringO 112,113, this reduction valve can with the 20 supporting uses of tracheae connection part.See shown in the accompanying drawing 1: tracheae connection part 20 is by being fastened in together and relatively turnable joint link 21 and gas-tpe fitting 22 constitute, wherein, joint link 21 is threaded with air inlet nut 11 outer ends, gas-tpe fitting 22 front ends are step-like, and insert in the suction port 111 at air inlet nut 11 middle parts, between the two by 112,113 sealings of O RunddichtringO.
When needs connect big capacity steel cylinder gas tank, only need gas-tpe fitting 22 is aimed at the suction port 111 of air inlet nut 11, tighten joint link 21, tracheae connection part 20 and air inlet nut 11 are firmly linked together, at this moment, gas-tpe fitting 22 front ends stretch in the suction port 111, and realize double seal by two O RunddichtringOs 112 and 113, use as safe as a house reliable.And when not needing to use big capacity steel cylinder gas tank, only need unscrew joint link 21, tracheae assembly 20 is pulled down from air inlet nut 11 got final product.
