Abstract
The utility model discloses a bottom valve, which comprises a rotary valve. The rotary valve is integrally molded with an outlet of the bottom valve, and the other side of the rotary valve is provided with a flange connected with a foot valve. The rotary valve of the bottom valve is integrated with the outlet of the valve body, thereby omitting a connecting structure of the rotary valve and the outlet of the traditional bottom valve, reducing potential leakage hazards of a sealing surface, increasing reliability of products, and reducing production and maintenance costs.
Description
Technical field
The utility model relates to a kind of bottom valve, particularly a kind of jar bottom valve of case tank car that is used for.
Background technique
As shown in Figure 1, the road tank vehicle bottom valve is substantially for 3 stops designs, and as first seal structures, rotary valve 2 exports 3 joints as second seal structures with bottom valve with foot valve 1 and stopcock 2 joints, and bottom valve outlet 3 and blanking cover 4 thereof are as the 3rd sealing configuration.In foot valve 1 and bottom valve outlet 3, be equipped with a flange 5, during assembling rotary valve 2 be clamped between two flanges 5, by screw rod 6 rotary valve 2 is clamped then.Above-mentioned three seal structures guarantees not occur leakage phenomenon in the tank car transportation process.But owing to there are three groups of sealing configurations, sealing surface is more, and structure is comparatively complicated, occurs problems such as sealing face leakage easily.In the today of pursuing efficient transportation, fault will influence whole transportation rhythm and cause economic loss.
The model utility content
The technical problems to be solved in the utility model is more in order to overcome in the prior art sealing surface of bottom valve, and there is the defective of leaking hidden danger in the mechanical mechanism complexity, provides a kind of simple in structure, and sealing surface is few, the integrated bottom valve that produce, maintenance cost is lower.
The utility model solves above-mentioned technical problem by following technical proposals:
A kind of bottom valve, it comprises a rotary valve, and its characteristics are that the outlet of this rotary valve one side and this bottom valve is formed in one, and the opposite side of this rotary valve is provided with one and is used for and a foot valve flange connecting.
Wherein, this rotary valve is ball valve, butterfly valve or stopcock.
Positive progressive effect of the present utility model is: the utility model integrates the butterfly valve and the valve outlet of bottom valve, thereby omitted the linkage structure of butterfly valve and outlet port in traditional bottom valve, thereby the raising reliability of products reduces the cost of producing and safeguarding.
Description of drawings
Fig. 1 is the structural representation of bottom valve of the prior art.
Fig. 2 is the butterfly valve among the utility model one embodiment and the structural representation in bottom valve outlet port.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figure 2, one end and the valve outlet 3 of the butterfly valve 2 of the bottom valve in the utility model are one-body molded, valve outlet 3 is provided with a blanking cover 4, the other end at butterfly valve 2 is provided with a flange 5, flange on this flange 5 and the foot valve 1 cooperates and is connected by screw rod 6, thereby form the bottom valve that has only the two seals face, reduced the potential threat of leaking.
In addition, say that prior art is clamped in butterfly valve being fixed between two flanges so all form a sealing surface in the both sides of butterfly valve, and two side flanges are at a distance of certain distance, for accurate assembling brings certain difficulty from assembly structure.The utility model has shortened the spacing between two flanges when reducing sealing surface, make that assembling is more accurately convenient.
Though more than described embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is limited by appended claims.Those skilled in the art can make numerous variations or modification to these mode of executions under the prerequisite that does not deviate from principle of the present utility model and essence, but these changes and modification all fall into protection domain of the present utility model.
Claims (2)
1. bottom valve, it comprises a rotary valve, it is characterized in that, and the outlet of this rotary valve one side and this bottom valve is formed in one, and the opposite side of this rotary valve is provided with one and is used for and a foot valve flange connecting.
2. bottom valve according to claim 1 is characterized in that, this rotary valve is ball valve, butterfly valve or stopcock.
