Abstract
The utility model discloses a cross valve special for alcoholization oil, which is essentially composed of a valve body, a valve core, a nut, a rubber ring and a handle. An outer end of the valve core is connected fixedly with the handle, an inner end of the valve core and the rubber ring which is sleeved on the inner end of the valve core are sleeved inside an inner chamber of the valve body, and outer threads arranged on an inner end wall of the valve core are threaded inside a screw hole of the inner chamber of the valve body. The nut is threaded on outer threads arranged on an outer wall of the valve body, and an inner end wall of the nut is butted on the rubber ring through a gasket and enables the rubber ring to dilate and deform to seal the inner chamber of the valve body. Due to the fact that the rubber ring serving as a sealing piece is sleeved between the valve body and the valve core, the cross valve is good in sealing performance, and the rubber ring is made of ethylene-propylene-diene monomer materials, thereby being good in corrosion resistance and having long service life.
Description
Technical field
The utility model relates to a kind of valve body, particularly relates to a kind of special-purpose cross valve of pure carburetion.
Background technique
The existing relatively energy (rock gas, diesel oil etc.) of alcoholic fuel has advantages such as energy-saving and environmental protection, so paid attention to by people.But also there are defectives such as burning is insufficient, combustion heat value is low in alcoholic fuel.Owing to have stronger corrosivity during the alcoholic fuel burning, make alcoholic fuel fuel-burning equipment and connecting pipeline get rusty easily.It is to requiring to have higher corrosion-resistant requirement as the cross valve that is connected with the alcoholic fuel fuel-burning equipment.
The model utility content
The purpose of this utility model is to provide a kind of special-purpose cross valve of pure carburetion of good airproof performance.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of special-purpose cross valve of pure carburetion, and it mainly is made up of valve body, spool, nut, rubber ring, handle; In the affixed handle in the outer end of described spool, the inner and socket of the spool rubber ring on it is nested with together and is located at the screw of external thread bolt connection at body cavity on the spool inner end wall in body cavity and spool the inner; Described nut is screwed onto on the outside thread of valve outer wall, the inner end wall of nut by the pad roof pressure on rubber ring and make rubber ring distortion expand and body cavity is sealed.
Described rubber ring adopts ethylene propylene diene monomer (EPDM) material to make.
After adopting such scheme,, make that sealing of the present utility model is better because the utility model is socketed with the rubber ring as Sealing between valve body and spool; And rubber ring of the present utility model adopts ethylene propylene diene monomer (EPDM) material to make, and has corrosion resistance preferably, long service life.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is an axonometric drawing of the present utility model;
Fig. 2 is a three-dimensional exploded view of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, the utility model is a kind of special-purpose cross valve of pure carburetion, and it mainly is made up of valve body 1, spool 2, nut 3, rubber ring 4, handle 5, pad 6.
The affixed handle 5 in the outer end of described spool 2, the inner and socket of spool 2 rubber ring 4 on it is nested with the outside thread of being located on spool 2 inner end wall in valve body 1 inner chamber 11 and spool 2 the inners 21 together and is screwed onto in the screw of valve body 1 inner chamber; Described nut 3 is screwed onto on the outside thread 12 of valve body 1 outer wall, and the inner end wall of nut 3, expands and rubber ring 4 is out of shape on rubber ring 4 by pad 6 roof pressures, with 11 sealings of valve body 1 inner chamber.
Described rubber ring 4 adopts ethylene propylene diene monomer (EPDM) material to make.
Installation process of the present utility model:
During use, the inner of spool 2 is placed through and is bolted in the inner chamber 11 of valve body 1; Nut 3 is screwed onto on the outside thread 12 of valve body 1 outer wall, the inner end wall of nut 3, expands and rubber ring 4 is out of shape on rubber ring 4 by pad 6 roof pressures.Just can open or close oil inlet passage of the present utility model by rotatable handle 5.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
Claims (2)
1. the special-purpose cross valve of a pure carburetion, it is characterized in that: it mainly is made up of valve body, spool, nut, rubber ring, handle; In the affixed handle in the outer end of described spool, the inner and socket of the spool rubber ring on it is nested with together and is located at the screw of external thread bolt connection at body cavity on the spool inner end wall in body cavity and spool the inner; Described nut is screwed onto on the outside thread of valve outer wall, the inner end wall of nut by the pad roof pressure on rubber ring and make rubber ring distortion expand and body cavity is sealed.
