Abstract
The invention relates to the technical field of valve, in particular to an autocontrol stop valve, comprising a valve body provided with a liquid inlet and a liquid outlet; wherein a liquid flow channel is formed between the liquid inlet and the liquid outlet; a valve clack is arranged in the valve body. The invention is characterized in that the flow channels of the liquid inlet and the liquid outlet employ a horizontal streamline flow channel; a channel communicated by the liquid inlet and a sealing port and a channel communicated by the liquid outlet and the sealing port all employ smooth curve transition; the latus rectum of the liquid flow channel formed by the flow channel and the latus rectum of the liquid inlet and the liquid outlet are equivalent in size. The autocontrol stop valve has the beneficial effects that: the structure is reasonable and simple, which leads the liquid flow to be smooth when passing through from the valve body, thus being capable of effectively improving the passing efficiency of the liquid flow, reducing the flow resistance of a liquid flowing out a middle cavity and the system energy consumption, effectively reducing the size of system temperature rising equivalent to the loss of heat conversion, and meeting the related national standards.
Description
[technical field]
The present invention relates to valve technology field, particularly a kind of automatic control stop valve.
[background technique]
At present, existing automatic control stop valve, it includes liquid entering hole and liquid outlet forms liquid chunnel, is provided with the sealed mouth of sealing fluid circulation road when being convenient to cut off in liquid chunnel.But its liquid entering hole of existing stop valve and liquid outlet are the forms by the horizontal channel is communicated to the sealed mouth in the liquid chunnel, and play seal action when cutting off liquid chunnel, its sealed mouth just must adopt to be provided with on the wall of liquid chunnel and stretch out piece, so just make that its passage just became narrow when liquid circulated overstocked sealing part, and the latus rectum of the connecting tube that links to each other with liquid chunnel is greater than the latus rectum at sealing mouth place, so just hinder the circulation of liquid stream, simultaneously, liquid circulation footpath in the NBS should reach the latus rectum of the connecting tube of same specification, does not meet NBS.
[summary of the invention]
Technical problem to be solved by this invention provides a kind of smooth logical stop valve of liquid that guarantees.
The technical solution adopted for the present invention to solve the technical problems is: a kind of automatic control stop valve, comprise the valve body that is provided with liquid entering hole and liquid outlet, between liquid entering hole and liquid outlet, form liquid chunnel, be provided with flap in the valve body, it is characterized in that: the liquid entering hole of described valve body and liquid outlet runner adopt horizontal streamline channel, the passage that passage that liquid entering hole is connected with sealed mouth and liquid outlet are connected with sealed mouth all adopts the smooth surface transition, the latus rectum sizableness of the latus rectum of the formed liquid chunnel of runner and liquid entering hole and liquid outlet.
Beneficial effect of the present invention: simple and reasonable for structure, when liquid stream passes through from valve body, just make liquid smooth logical, can effectively improve the efficient of passing through of liquid stream, the flow resistance and the system energy consumption that flow out lumen are reduced, effectively reduce the thermal transition loss that system heats up, also met the concerned countries standard simultaneously.
