Abstract
The utility model relates to a ball valve which comprises a valve core. The valve core comprises a valve core main body and a valve core handle. The valve core main body is in a ball shape. The valve core main body is provided with an up-and-down through hole, and the valve core main body is disposed in a ball valve shell. The rear end of the valve core main body is provided with the valve core handle, and the valve core handle penetrates through a valve core handle hole arranged on the ball valve shell corresponding to the valve core handle. A seal ring groove is disposed on the valve core handle, and a seal ring is arranged in the seal ring groove. Grooves are respectively disposed at a right end and a left end of the valve core main body. A plastic hard sleeve is sleeved on an outer side of the seal ring. The ball valve shell comprises two ball valve half-shells, each ball valve half-shell is provided with a connection mouth matched with the through hole on the valve core main body, and symmetrical half-holes are respectively arranged on lower portions of sidewalls of the ball valve half-shells. The ball valve has the advantages of being simple in structure, good in sealing performance, not prone to water seepage and small in rotating resistance of the valve core, and meanwhile, the valve core is not prone to automatically rotating due to water pressure.
Description
Technical field
The utility model relates to a kind of ball valve.
Background technique
In industrial or civilian infrastructure, utilize the pipeline fed sheet of a media usually; Wherein since pressure or variation of temperature to regulate pipeline; In pipeline, use controlling mechanism for regulating flow, ball valve especially is to guarantee best operating conditions and safety of environment.Ball valve normally uses the spheroid that has circular channel as opening and closing element, and spheroid is realized the valve of switching motion with the rotation of valve body.The open-shut device of ball valve is a spheroid that through hole is arranged, and winds the axis rotation perpendicular to passage, thereby reaches the purpose that opens and closes passage.But existing ball valve moment of torsion when opening and closing is big, makes its wearing and tearing very big, and operating life is shorter, and spool is easy to receive the pressure of medium to rotate automatically again in addition, and sealing is poor.
The model utility content
The purpose of the utility model provides a kind of ball valve, overcomes the deficiency of above-mentioned aspect in the existing product.
The purpose of the utility model is to realize through following technological scheme:
A kind of ball valve comprises spool, and said spool comprises spool main body and spool handle; The spool main body is a spheroid, and the spool main body is provided with lower through-hole, and the spool main body is arranged in the ball valve shell; The spool body rear is provided with the spool handle; The spool handle passes on the ball valve shell and the corresponding spool handle hole of spool handle, and the spool handle is provided with seal groove, is provided with seal ring in the seal groove.Said spool main body right ends is equipped with groove.The said seal ring outside is with plastics and applies arbitrarily.Said ball valve shell comprises two ball valve half shells, ball valve half shell top be provided with the spool main body on the connection mouth that is complementary of through hole, ball valve half shell side wall bottom is provided with half hole of symmetry.
The beneficial effect of the utility model is: simple in structure, good airproof performance is difficult for infiltration, and the valve core rotation resistance is little, and the pressure that the while spool is not subject to water again rotates automatically.
Description of drawings
According to accompanying drawing the utility model is done further explain below.
Fig. 1 is the structural representation of the described a kind of ball valve of the utility model embodiment;
Fig. 2 is the structural representation of the spool of the described a kind of ball valve of the utility model embodiment;
Fig. 3 is the plan view of the spool of the described a kind of ball valve of the utility model embodiment;
Fig. 4 is the structural representation of the ball valve shell of the described a kind of ball valve of the utility model embodiment;
Fig. 5 is the structural representation of ball valve half shell of the described a kind of ball valve of the utility model embodiment.
Among the figure:
1, spool; 101, spool main body; 102, spool handle; 103, through hole; 104, seal ring; 105, groove; 106, plastics are applied arbitrarily; 2, ball valve shell; 201, spool handle hole; 202, ball valve half shell; 203, connection mouth; 204, half hole.
Embodiment
Shown in Fig. 1-5, the described a kind of ball valve of the utility model embodiment comprises spool 1; Said spool 1 comprises spool main body 101 and spool handle 102; Spool main body 101 is a spheroid, and spool main body 101 is provided with lower through-hole 103, and spool main body 101 is arranged in the ball valve shell 2; Spool main body 101 rear ends are provided with spool handle 102; Spool handle 102 passes on the ball valve shell 2 and spool handle 102 corresponding spool handle holes 201, and spool handle 102 is provided with seal groove, is provided with seal ring 104 in the seal groove.Said spool main body 101 right ends are equipped with groove 105, can avoid spool main body 101 left ends or right-hand member to receive the pressure of water on the one hand, rotate voluntarily, can reduce the volume of spool main body 101 on the other hand.Said seal ring 104 outsides are with plastics and apply arbitrarily 106, and plastics are applied arbitrarily and 106 can be made tightr that ball valve half shell 202 connects, and make water be not easy to exosmose better tightness.Said ball valve shell 2 comprises two ball valves, half shell 202; Ball valve half shell 202 tops be provided with spool main body 101 on the connection mouth 203 that is complementary of through hole 103; Ball valve half shell 202 lower sidewall are provided with half hole 204 of symmetry, 204 pairs in half hole of two ball valves, half shell 202 are formed spool handle hole 201 well and two ball valve half shells are connected can form a ball valve shell 2.
The utility model is not limited to above-mentioned preferred forms; Anyone can draw other various forms of products under the enlightenment of the utility model; No matter but on its shape or structure, do any variation; Every have identical with a application or akin technological scheme, all drops within the protection domain of the utility model.
