Abstract
The utility model discloses a valve for gas and liquid transmission, in particular to a non-return valve in an overall structure, which aims at solving the problems of complicated structure, worse sealing property, slower reaction for closing the valve, easiness in corruption, shorter service life, trouble in exchange and larger use cost in an existing non-return valve. The non-return valve is characterized in that a cylindrical valve body and a tapered valve cap are provided; the top end of the valve cap is provided with a cut valve outlet; and the self-closing type non-return valve is the overall structure which is formed by one-off compression molding.
Description
Technical field
The utility model relates to the valve of a kind of gas and liquid conveying, particularly a kind of integrally-built one-way cock.
Background technique
Be applied at present liquid, gas delivery one-way valve adopt mechanical structure more, rely on the elastic force of spring to promote pellet shot from a slingshot or valve core throttle down.Therefore problems such as wearing and tearing, spring failure in use often occur, cause seepage phenomenon and big noise when closing, especially in corrosive gas or liquid course of conveying, valve is corroded easily, causes whole valve to scrap.Because of existing one-way valve structures is complicated, sealability is relatively poor, the throttle down reaction is slow, be prone to be corroded, working life is short, change trouble, and user cost is bigger.
The model utility content
The utility model technical problem to be solved provide a kind of rapidly opened and closed, simple in structure, service condition extensively, self-closing box-like one-way valve that reliability is higher.
The technological scheme that the utility model solves the problems of the technologies described above is following: a kind of self-closing box-like one-way valve; Comprise columniform valve body and conical bonnet; The valve export that said bonnet top has cutting to form, the overall structure that said self-closing box-like one-way valve is disposable compression molding.
The beneficial effect of the utility model is: the present invention is in corrosivity or noncorrosive gas, liquid input tube road or container.Simple in structure, installation and maintenance is convenient, good corrosion resistance, and good seal performance does not have noise, and user cost is cheap.
Preferably, described self-closing box-like one-way valve, said valve body up and down two end faces are respectively equipped with flange plate, through flange plate directly is installed on the position that will install, with valve body be fixed on want on the installed device.
Preferably, described self-closing box-like one-way valve, said valve inner is provided with metal frame, and said metal frame one end is provided with screw thread, and the fastening piece of forming through packing ring and nut is installed in valve body on the equipment or device that needs this valve body of installation.
Preferably, described self-closing box-like one-way valve, said valve body is provided with the flange plate that the surface is evenly equipped with through hole, and the fastening piece that said flange plate is formed through bolt, packing ring and nut snugly fits into to be needed to install on the equipment or device of this valve body.

Embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
Embodiment one
As shown in Figure 3, self-closing box-like one-way valve body 1, there is bonnet 2 on the top; There is outlet 3 on said bonnet 2 tops; Two end faces up and down of valve body 1 are provided with flange plate, directly are installed on the external equipment 4, when the gas of valve both sides or liquid have certain pressure; Flange plate can tightly be pressed on the external equipment 4 that will install, thereby guaranteed good sealing.
Embodiment two
As shown in Figure 4, self-closing box-like one-way valve body 1 inside is provided with metal frame, and metal frame one end is provided with screw thread, through the fastening piece that packing ring 6 and nut 5 are formed, snugly fit on the external equipment 4 that will install.
Embodiment three
As shown in Figure 5, self-closing box-like one-way valve body 1 is provided with and has the flange plate that is uniformly distributed with through hole, the fastening piece of forming through bolt 7, packing ring 6 and nut 5 snugly fit on the installed device of wanting 4.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
