Abstract
The utility model discloses a connecting piece for a valve ball and a valve rod. The connecting piece comprises a connecting piece body, the valve ball and the valve rod, the inside of the connecting piece body is hollow and is provided with a valve ball groove, the upper portion of the connecting piece body is provided with an extending end, a through hole is formed in the extending end, the extending end and the valve ball groove of the connecting piece body are communicated through the through hole to form a valve rod groove, the valve rod enters through the through hole and is connected with the valve ball in the valve ball groove of the connecting piece body, and three first reinforcing ribs are further arranged on the side wall of the connecting piece body; a fixed block is arranged in the valve rod groove and matched with the valve rod in a sleeved mode, two second reinforcing ribs symmetrical vertically are arranged on the outer wall of the fixed block, through the three first reinforcing ribs, the strength of the valve ball is improved, and roundness of the valve ball is ensured. The fixed block arranged in the valve rod groove can ensure that the valve rod is not deviated, and the two second reinforcing ribs on the fixed block have the function of increasing torque; the valve ball and the valve rod can be effectively connected together through the connecting piece, and fastening performance of connection is improved.
Description
Technical field
The utility model belongs to valve system part field, relate in particular to a kind of for valve system, the link of valve ball and valve rod.
Background technique
In specification, various valves various in style, the valve that accounts for valve total amount 80% can be used valve ball.Little extremely several millimeters, arrive greatly several meters, be all valve ball.In existing design, valve ball is generally to separate design, manufacture with valve rod.In manufacture, also have a lot of restraining factors, first, the difficulty of the manufacture of valve ball valve rod is very large, complex process, and machining accuracy is not high, and efficiency is very low; Secondly, in the assembly process of valve, because valve rod, valve ball are two parts, need to first install and refill in valve body, cause inconvenience is installed, assembling difficulty, efficiency is not high.
Summary of the invention
In order to address the above problem, the utility model provides the link of a kind of valve ball and valve rod, and described link can
Connect valve ball and valve rod, make the assembling of valve ball and valve rod convenient.
Adopt following technological scheme: the link of a kind of valve ball and valve rod, comprises a body, valve ball and valve rod, the hollow valve ball groove that is set to of described body interior for this reason; Body top has external part, in external part, there is a through hole, described through hole is communicated with external part and the valve ball groove of body, form valve rod groove, valve rod enters by this through hole and connects the valve ball in body valve ball groove, it is characterized in that: on described body sidewall, be also provided with three the first stiffening ribs, described the first stiffening rib inner side is one-body molded with body sidewall, and outside is transition circle arcuation; In described valve rod groove, be provided with fixed block, described fixed block coordinates with via clearance, fixed block cover and on valve rod; Described fixed block outer wall is provided with two laterally zygomorphic the second stiffening ribs, and described the second stiffening rib and valve rod groove inwall have gap.
Further, the material of described link is PPSU.
According to such technological scheme, can promote valve ball intensity and guarantee valve ball circularity by three the first stiffening ribs.The fixed block arranging in valve rod groove can guarantee that skew does not appear in stem position, and two the second stiffening ribs on fixed block have the effect that increases moment of torsion; By such link, can make valve ball and valve body effectively link together, improve the tightness connecting.
Accompanying drawing explanation
Fig. 1 is the plan view of the present embodiment.
Fig. 2 is the side view of the present embodiment.
Fig. 3 is the plan view of the present embodiment.
Embodiment
Referring to accompanying drawing.The present embodiment comprises that material is body 1, valve ball and the valve rod of PPSU, and described body 1 boring is set to valve ball groove 2; Body 1 top has external part 3, in external part 3, there is a through hole, described through hole is communicated with external part and the valve ball groove of body, form valve rod groove 4, valve rod enters by this through hole and connects the valve ball in valve ball groove 2, in the forward and backward and lower wall of described body 1, respectively establish first stiffening rib 5, described the first stiffening rib 5 inner sides and body sidewall are one-body molded, and outside is transition circle arcuation; In described valve rod groove 4, be provided with fixed block 6, described fixed block 6 coordinates with via clearance, fixed block 6 cover and on valve rod; Described fixed block 6 outer walls are provided with two laterally zygomorphic the second stiffening ribs 7, and described the second stiffening rib 7 has gap with valve rod groove inwall.
By three the first stiffening ribs 5 on body sidewall, promote valve ball intensity, guarantee valve ball circularity.The fixed block 6 of valve rod groove 4 interior settings can guarantee that stem position there will not be skew, and two the second stiffening ribs 7 on fixed block 6 have the effect that increases moment of torsion.
Claims (2)
1. a link for valve ball and valve rod, comprises a body, valve ball and valve rod, the hollow valve ball groove that is set to of described body interior; Body top has external part, in external part, there is a through hole, described through hole is communicated with external part and the valve ball groove of body, form valve rod groove, valve rod enters by this through hole and connects the valve ball in body valve ball groove, it is characterized in that: on described body sidewall, be also provided with three the first stiffening ribs, described the first stiffening rib inner side is one-body molded with body sidewall, and outside is transition circle arcuation; In described valve rod groove, be provided with fixed block, described fixed block coordinates with via clearance, fixed block cover and on valve rod; Described fixed block outer wall is provided with two laterally zygomorphic the second stiffening ribs, and described the second stiffening rib and valve rod groove inwall have gap.
2. according to the link of a kind of valve ball claimed in claim 1 and valve rod, it is characterized in that: the material of described link is PPSU.
