Abstract
The utility model relates to the technical field of valves, in particular to a hammered-steel disconnecting valve, which comprises a valve body and a valve stem arranged inside the valve body. The valve stem comprises an upper valve stem and a lower valve stem; a hand lever is connected with the upper end part of the upper valve stem, and the lower end part of the upper valve stem is connected with the upper end part of the lower valve stem; the upper valve stem is in threaded connection with the valve body; a valve-ball fixing sleeve is arranged at the lower end part of the lower valve stem; a valve chamber is formed on the valve body; the valve ball fixing sleeve is positioned in the valve chamber; and a valve-ball is arranged in an inner cavity of the valve-ball fixing sleeve. The hammered-steel disconnecting valve is characterized in that the valve-ball fixing sleeve is in threaded connection with the lower valve stem. Compared with the prior art, the hammered-steel disconnecting valve has the advantages that the valve-ball fixing sleeve of the valve-ball is in threaded connection with the lower valve stem, and the valve-ball can be replaced through taking down the valve-ball fixing sleeve when in replacement instead of replacing the whole valve stem, so that the loss is reduced.
Description
[technical field]
The utility model relates to a kind of valve technology field, particularly about a kind of forged steel stop valve.
[background technique]
In the prior art, high temperature and high pressure cut-off valve often adopts the global-type valve ball, and valve ball and valve rod are fixed as one.High temperature and high pressure cut-off valve is after using a period of time, and valve ball damages easily, must often change, and valve rod also must be changed together, and the cost of valve rod is often than higher, and this has just caused waste and loss, and old friends need find out the way that addresses this problem.
[summary of the invention]
The utility model purpose provides a kind of forged steel stop valve, overcomes the shortcoming of prior art, can directly change valve ball when valve ball damages, and must not change valve rod, avoids unnecessary loss.
For achieving the above object, the technical solution adopted in the utility model is: a kind of forged steel stop valve, comprise valve body, be arranged on the valve rod in the described valve body, described valve rod comprises upper valve rod, lower valve rod, the upper end portion of described upper valve rod is connected with handle, the underpart of described upper valve rod is connected with the upper end portion of lower valve rod, described upper valve rod is threaded mutually with described valve body, the underpart of described lower valve rod is provided with the valve ball fixed cover, described valve body has valve pocket, described valve ball fixed cover is positioned at described valve pocket, is provided with valve ball in the inner chamber of described valve ball fixed cover, and described valve ball fixed cover is threaded mutually with described lower valve rod.
The utility model compared with prior art has following advantage: adopt between the valve ball fixed cover of valve ball and the lower valve rod to be threaded, desirable lower valve ball fixed cover and needn't be changed whole valve rod changing valve ball during replacing, has reduced loss.
[description of drawings]
Fig. 1 is a main sectional view of the present utility model;
Fig. 2 is the enlarged view of valve ball and lower valve rod;
Referring to Fig. 1, Fig. 2,1 is lower valve rod, and 2 is spring, and 3 is valve ball, and 4 is the valve ball fixed cover, 5 is handle, and 6 is valve body, and 7 is pipe joint, and 8 is pipeline, and 9 is first threaded connection place, 10 is second threaded connection place, and 11 is upper valve rod, and 12 is valve pocket, and 13 is the fluid inlet passage, and 14 is the fluid output channel.
[embodiment]
Referring to accompanying drawing 1, a kind of forged steel stop valve comprises valve body 6, is arranged on the valve rod in the described valve body 6.Described valve rod comprises upper valve rod 11, lower valve rod 1, and the upper end portion of described upper valve rod 11 is connected with handle 5, and the underpart of described upper valve rod 11 is connected with the upper end portion of lower valve rod 1.Described upper valve rod 11 be threaded mutually with described valve body 6 (seeing screw thread first joint 9).The underpart of described lower valve rod 1 is provided with valve ball fixed cover 4, and described valve body 6 has valve pocket 12, and described valve ball fixed cover 4 is positioned at described valve pocket 12, is provided with valve ball 3 in the inner chamber of described valve ball fixed cover 4.The diameter of the infraoral of described valve ball fixed cover 4 is less than the diameter of described valve ball 3, and valve ball 3 retainings are at the opening of valve pocket 12.Unscrew handle 5, upper valve rod 11 just drives lower valve rod 1 and moves upward, and valve ball 3 is also followed and moved upward, and until the opening of valve ball 3 disengaging valve pockets 12, fluid just can flow to fluid output channel 14 in fluid inlet passage 13.
Referring to accompanying drawing 2, described valve ball fixed cover 4 be threaded mutually with described lower valve rod 1 (seeing screw thread second joint 10).When valve ball 3 is damaged in use for some time, can back out valve ball fixed cover 4, from valve ball fixed cover 4, take out valve ball 3, be tightened on the lower valve rod 1 in the valve ball fixed cover 4 of again valve ball 3 being packed into after the replacing.
Referring to each accompanying drawing, be provided with spring 2 between described valve ball 3 and the described lower valve rod 1.When valve ball 3 and valve ball fixed cover 4 were installed on the lower valve rod 1, spring 2 was in pressured state, valve ball 3 was fastened on the lower end mouth of valve ball fixed cover 4, in case leak-stopping water.When backing out valve ball fixed cover 4, be subjected to the tension force effect of spring 2, take off valve ball fixed cover 4 also than being easier to.
Claims (3)
