Abstract
The utility model provides a high temperature high pressure stop valve, comprising a valve body and a valve rod which is arranged in the valve body. The valve rod comprises an upper valve rod and a lower valve rod. The upper end of the upper valve rod is connected with a handle, and the lower end of the upper valve rod is connected with the upper part of the lower valve rod. The upper valve rod is in screw connection with the valve body. The lower end of the lower valve rod is provided with a valve ball fixing sleeve. The valve body is provided with a valve cavity. The valve ball fixing sleeve is positioned in the valve cavity. A valve ball is arranged in the inner cavity of the valve ball fixing sleeve. The valve ball fixing sleeve is in screw connection with the lower valve rod. When the valve ball is damaged and needed to be replaced, the valve ball fixing sleeve is directly screwed from the lower valve rod, the old valve ball is fetched out, the new valve ball is provided, and the entire valve rod is not needed to be replaced.
Description
Technical field
The utility model relates to a kind of high temperature and high pressure cut-off 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 high temperature and high pressure cut-off 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 high temperature and high pressure cut-off 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, be provided with valve ball in the inner chamber of described valve ball fixed cover, described valve ball fixed cover is threaded mutually with described lower valve rod.
Because technique scheme utilization, 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 to be changing valve ball during replacing, and needn't change whole valve rod, reduced loss.

Accompanying drawing 2 is the enlarged view of valve ball and lower valve rod;
Wherein: 1, lower valve rod; 2, spring; 3, valve ball; 4, valve ball fixed cover; 5 handles; 6, valve body; 7, pipe joint; 8, pipeline; 9, first threaded connection place; 10, second threaded connection place; 11, upper valve rod; 12, valve pocket; 13, fluid inlet passage; 14, fluid output channel;
Embodiment
Referring to accompanying drawing 1, a kind of high temperature and high pressure cut-off 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.
