Abstract
The utility model discloses a cut off valve, which has the advantage that the smoothness of the liquid flowing can be ensured. The cut off valve comprises a vale body provided with a liquid inlet and a liquid outlet, a liquid flowing channel is formed between the liquid inlet and the liquid outlet, a valve core is arranged in the valve body, a sealing mouth is arranged on the liquid flowing channel, the head end of the vale core is properly matched with the sealing mouth, and the drift diameter of the formed liquid flowing channel is equivalent with the drift diameters of the liquid inlet and the liquid outlet. Through the drift diameter of the formed liquid flow channel being arranged into the equivalent drift diameters with the drift diameters of the liquid inlet and the liquid outlet, when the liquid flow passes through the valve body, the liquid flow can be smooth, the passing efficiency of the liquid flow can be effectively improved, and simultaneously the relevant national standard also is obeyed. The utility model is particularly suitable for being promoted and applied on the various liquid flowing occasions where the cut off valve is required to be installed.
Description
Technical field
The utility model relates to a kind of hydrovalve, especially relates to a kind of stop valve.
Background technique
At present, existing stop valve valve body as shown in Figure 4, it includes liquid entering hole and liquid outlet and 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.
The model utility content
Technical problem to be solved in the utility model provides a kind of smooth logical stop valve of liquid that guarantees.
The technological scheme that its technical problem that solves the utility model adopts is: 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 spool in the valve body, liquid chunnel is provided with sealed mouth, spool head and sealed mouth are suitable, the latus rectum sizableness of the latus rectum of formed liquid chunnel and liquid entering hole and liquid outlet.Latus rectum by liquid chunnel is set to the latus rectum sizableness with liquid entering hole and liquid outlet, when liquid stream passes through from valve body like this, just makes liquid smooth logical, can effectively improve the efficient of pass through of liquid stream, and the while also meets the concerned countries standard.
As the preferred version of technique scheme, the passage that passage that liquid entering hole is connected with sealed mouth and liquid outlet are connected with sealed mouth all adopts circular shape.
Further be, described valve body adopts plastic production, and the spool head adopts metallic material to make.When making spool head and valve seal like this, can utilize the hardness of material of metal and the pliability of plastics directly to seal, not need seal ring to get final product.
Further be that described valve body is structure as a whole.
Further be that the shaft axis of described liquid entering hole and liquid outlet is on same straight line.
The beneficial effects of the utility model are, latus rectum by liquid chunnel is set to the latus rectum sizableness with liquid entering hole and liquid outlet, when liquid stream passes through from valve body like this, just makes liquid smooth logical, can effectively improve the efficient of passing through of liquid stream, also meet the concerned countries standard simultaneously.Valve body adopts plastic production, the spool head adopts metallic material to make, when making spool and valve seal, can utilize the hardness of material of metal and the pliability of plastics directly to seal, do not need seal ring to get final product, be particluarly suitable for the place that various liquid communication occasions need install stop valve and promote the use of.

Be labeled as among the figure: valve body 1, liquid entering hole 2, liquid outlet 3, spool 4, sealed mouth 5, spool head 6.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, stop valve of the present utility model, comprise the valve body 1 that is provided with liquid entering hole 2 and liquid outlet 3, between liquid entering hole 2 and liquid outlet 3, form liquid chunnel, be provided with spool 4 in the valve body 1, liquid chunnel is provided with sealed mouth 5, and spool head 6 is suitable with sealed mouth 5, the latus rectum sizableness of the latus rectum of formed liquid chunnel and liquid entering hole 2 and liquid outlet 3.Latus rectum by liquid chunnel is set to the latus rectum sizableness with liquid entering hole 2 and liquid outlet 3, when liquid stream passes through from valve body 1 like this, just makes liquid smooth logical, can effectively improve the efficient of pass through of liquid stream, and the while also meets the concerned countries standard.
In the above-described embodiment, the latus rectum of liquid chunnel is set to can have multiple with the sizable mode of latus rectum of liquid entering hole 2 and liquid outlet 3, as can be as shown in Figure 5, the flow channel at liquid entering hole 2 places is curved downwards earlier, upwards link to each other again by the horizontal channel then with sealed mouth 5, flow out from liquid outlet 3 again, but this mode needs just can obtain finished product after the moulding of twice.And as preferred embodiment, the passage that passage that liquid entering hole 2 is connected with sealed mouth 5 and liquid outlet 3 are connected with sealed mouth 5 all adopts circular shape.Can guarantee the unobstructed of liquid stream circulation so fully, reduce liquid flowing resistance, improve the circulation efficiency of liquid stream, and after adopting circular shape, can obtain finished product, reduce to manufacture cost greatly by once-through.
In order to make when cutting off liquid chunnel, when playing seal action, also can simplify seal arrangement, described valve body 1 adopts plastic production, and spool head 6 adopts metallic material to make.And after adopting in such a way, when making spool head 6 like this, can utilize the hardness of material of metal and the pliability of plastics directly to seal with valve body 1 sealing, do not need seal ring to get final product.Valve body 1 can be to adopt several sections to be spliced, but in order to reduce production process, described valve body 1 is structure as a whole.Valve body 1 can adopt once injection moulding to get final product when moulding like this, makes to have simplified manufacturing process, makes manufacturing more convenient.
In order to guarantee after installation, but connect the connecting tube horizontal arrangement of liquid entering hole 2 and liquid outlet 3, the shaft axis of described liquid entering hole 2 and liquid outlet 3 is on same straight line.
