Abstract
The invention relates to a low-damping ball valve. The low-damping ball valve comprises a valve body (2), a valve element (1) mounted in the valve body (2), and a handle (3) positioned at the outside of the valve body (2); the valve element (1) is connected with the handle (3) through a valve rod (4); a cavity (5) with spacing of 0.15-2.5mm is formed between the valve element (1) and the inner wall of the valve body (2); at least two balls (6) are arranged on the outer surface of the valve element (1); a pressure spring (7) is arranged between each ball (6) and the valve element (1). The low-damping ball valve is simple in structure and convenient to use; in addition, the frictional force between the valve element and the valve body can be effectively reduced while the sealing performance of the valve is ensured during use; therefore, the operation flexibility of the valve is improved, and moreover, the purpose of prolonging the service life of the valve can be reached.
Description
Technical field
The present invention relates to a kind of low resistance ball valve, belong to ball valve valve technology field.
Background technique
Ball valve a kind ofly drives spherical valve core make the valve that spool rotates around valve rod by valve rod, it is mainly used in blocking or connect the medium in pipeline, have in industry-by-industry and use widely, but find in long-term use, in presently used ball valve, sealing is main relies on the seal ring and spool that arrange between spool and valve body and valve body contact to seal, although this structure can meet the needs of use, but the rubbing surface simultaneously too increased between spool and valve body, thus easily cause between spool and valve body on the one hand and damage because of friction, also easily occur that the rotation caused because of reasons such as corrosion between spool and valve body is dumb on the other hand, thus have influence on the normal use of valve, for the deficiency existing for current ball valve, needs are used with satisfied reality in the urgent need to developing a kind of ball valve.
Summary of the invention
For the deficiency that prior art exists, the invention provides the low resistance ball valve that a kind of structure is simple, easy to use, effectively reduce the frictional force between spool and valve body, improve the flexibility of valve manipulation on the one hand, also reach the object extending valve working life on the other hand.
To achieve these goals, the present invention realizes by the following technical solutions:
A kind of low resistance ball valve of the present invention, comprise valve body, be arranged on the spool of valve inner and be positioned at the handle outside valve body, spool is connected with handle by valve rod; The inwall of spool and valve body forms the cavity that spacing is 0.15-2.5 millimeters, is provided with at least two balls at the outer surface of described spool, is provided with pressure spring between described ball and spool.
Further, lubricant oil is provided with in described cavity.
Further, described valve body and ball contact face place are provided with sliding-groove.
Structure of the present invention is simple, easy to use, and in using while guaranteeing valve seal performance, effectively reduces the frictional force between spool and valve body, improves the flexibility of valve manipulation on the one hand, also reaches the object in the working life extending valve on the other hand.
Accompanying drawing explanation
The present invention is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present invention.
Each label in figure: spool 1, valve body 2, handle 3, valve rod 4, cavity 5, ball 6, pressure spring 7, lubricant oil 8, sliding-groove 9.
Embodiment
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
A kind of low resistance ball valve as described in Figure 1, the handle 3 comprising valve body 2, be arranged on the spool 1 of valve body 2 inside and be positioned at outside valve body 2, spool 1 is connected with handle 3 by valve rod 4.
Spool 1 forms with the inwall of valve body 2 cavity 5 that spacing is 0.15-2.5 millimeters, is provided with two balls 6, is provided with pressure spring 7 between described ball 6 and spool 1 at the outer surface of spool 1.
In the present embodiment, in cavity 5, be provided with lubricant oil 8.
In the present embodiment, valve body 2 and ball 6 surface of contact place are provided with sliding-groove 9.
Structure of the present invention is simple, easy to use, and in using while guaranteeing valve seal performance, effectively reduces the frictional force between spool and valve body, improves the flexibility of valve manipulation on the one hand, also reaches the object in the working life extending valve on the other hand.
More than show and describe basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
