Abstract
The utility model discloses a ball valve with a retaining part, which comprises a valve body, a valve seat, a spherical valve spool, a valve stem and a handle, wherein the valve stem is mounted in a valve stem mounting passage. A cylindrical groove is disposed on the lower surface of the spherical valve spool and is spaced and not communicated with a water flow passage of the spherical valve spool, the retaining part is arranged on the valve body below the cylindrical groove, one end of the retaining part is clamped into the cylindrical groove while the other end is fixed on the valve body, and the shape of the portion of the retaining part clamped into the cylindrical groove matches with that of the cylindrical groove. The retaining part is mounted under the spherical valve spool, so that the spherical valve spool cannot deviate even in the condition with sand or hard objects, accordingly displacement of the valve stem cannot be affected, and water leakage of the valve stem mounting passage is prevented effectively. In addition, the ball valve increases the quality of products and prolongs the service life of the products.
Description
Technical field:
The utility model relates to a kind of ball valve that has retention means.
Background technique:
Ball valve is a kind of valve that switch is rapid, easy to operate, fluid resistance is little, simple in structure that has, and is widely used in controlling the liquid conveying and the civilian draining of industry.General ball valve comprises valve body, valve seat and spheroid spool at present, with the valve rod that the spheroid spool is connected, is used for the nut of valve stem seal, and the handle that links to each other with valve rod.Thereby drive the spheroid valve core rotation through handle interlock valve rod, realize the function of switch.Owing to sometimes have some grains of sand or other hard things in the tap water; when through valve body the time; might fall near the spheroid spool; in the time of the spinning ball spool, the grains of sand or hard thing may enter in the valve seat of upper and lower of spheroid spool, and spool just might rub when so just making rotational valve core; the spool that makes departs from the tram; and then make displacement of valve rod, and influence the seal that valve rod is installed passage, leak thereby cause valve rod that passage is installed.
Summary of the invention:
The purpose of this utility model provides a kind of ball valve that has retention means, and this ball valve can effectively prevent the generation that ball valve leaks.
For addressing the above problem, the utility model is implemented by the following technical programs:
The ball valve that has retention means of the present utility model, comprise valve body, valve seat, spheroid spool, be installed on valve rod and handle in the valve rod installation passage, on the surface below of described spheroid spool, have cylinder shape groove, the flow channel of this groove and spheroid spool is separated by, be not communicated with, on the valve body below the cylinder shape groove, be provided with retention means, this retention means one end snaps in the cylinder shape groove, the other end is fixed on the valve body, and shape and cylinder shape groove that retention means snaps in part in the cylinder shape groove match.
Above described spheroid spool, the below and arranged on left and right sides of valve seat preferably is respectively equipped with first, second Sealing.
Below described spheroid spool, the top and arranged on left and right sides of valve seat preferably is respectively equipped with the 3rd, the 4th Sealing.
And arranged on left and right sides preferably is respectively equipped with the 5th, the 6th Sealing in the valve rod installation passage of described valve rod both sides.
Can spheroid spool and the solid positive position of valve rod be prevented to leak at above-mentioned six local Sealings that increase.
The utility model is by installing a retention means below the spheroid spool, even make that the spheroid spool can deviation position under the situation that sand or hard thing are arranged yet, therefore can not influence displacement of valve rod, thereby prevented that effectively valve rod from installing leaking of passage.Thereby improved the quality of product, prolonged the working life of product.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
1, valve body; 2, valve seat; 3, spheroid spool; 4, valve rod; 5, handle; 6, retention means; 7, valve rod is installed passage; 11, first Sealing; 12, second Sealing; 13, the 3rd Sealing; 14, the 4th Sealing; 15, the 5th Sealing; 16, the 6th Sealing.
Embodiment:
Below be to advance an explanation to of the present utility model, rather than to restriction of the present utility model.
As shown in Figure 1, the ball valve that has retention means of the present utility model, comprise valve body 1, valve seat 2, spheroid spool 3, be installed on valve rod 4 and handle 5 in the valve rod installation passage 7, on the surface below of described spheroid spool 3, have cylinder shape groove, the flow channel of this groove and spheroid spool 3 is separated by, on the valve body below the cylinder shape groove 1, be provided with retention means 6, this retention means one end snaps in the cylinder shape groove, the other end is fixed on the valve body, and shape and cylinder shape groove that retention means 6 snaps in part in the cylinder shape groove match.Above described spheroid spool, the below and arranged on left and right sides of valve seat is respectively equipped with first Sealing 11 and second Sealing 12.Below described spheroid spool, the top and arranged on left and right sides of valve seat is respectively equipped with the 3rd Sealing 13 and the 4th Sealing 14.And arranged on left and right sides is respectively equipped with the 5th Sealing 15 and the 6th Sealing 16 in the valve rod installation passage of described valve rod both sides.
