Description
Technical field
The utility model belongs to valve technology field, is related to a kind of unidirectional grease pouring valve, more particularly to a kind of greasing with unidirectionally
Grease pouring valve.
Background technology
Existing unidirectional grease pouring valve is mainly by bonnet (sequence number 1), steel ball (sequence number 7), spring (sequence number 4), valve body (sequence number 2) group
Into (see accompanying drawing 1), it is bonded by steel ball with valve body inner face and forms sealing, poor sealing performance.In addition, its spring is fixed, bullet
Spring pretightning force size is unadjustable, and for spring in the case of long-time stress, being easily deformed causes elastic force to weaken, when spring itself
When elastic force weakens, the sealing effectiveness of spheroid and valve body can be influenceed；Again because spring is fixed, so can not be by adjusting spring
Reduction length ensures initial tension of spring, can only finally scrap, and shortens valve service life.
Utility model content
The utility model aims to provide a kind of unidirectional grease pouring valve, can improve the sealing property of grease pouring valve, and convenient regulation bullet
Support force of the spring to valve element.
To reach above-mentioned purpose, the technical solution adopted in the utility model is as follows：
A kind of unidirectional grease pouring valve, including bonnet, valve body, valve element, spring and adjusting screw, the valve body have greasing passage,
The threaded one end of the bonnet and valve body connects and covers the entrance of greasing passage, and the valve element and spring are located at greasing passage
In, it is conical surface seal between the valve element and valve body, the spring one end is pressed on adjusting screw, and the spring other end withstands on valve element
On, the adjusting screw coordinates located at the exit of greasing passage and with valve body screw thread, and axial direction is provided with the adjusting screw
Medium through hole.
Wherein, described valve element one end is conical structure, and the valve element other end is cylindrical structural, the conical structure with
Valve body sealing surface coordinates.
Further, the lateral wall of the cylindrical structural has axial straight trough, the straight trough insertion cylindrical structural
Top surface and bottom surface, the straight trough at least two, straight trough is equidistantly spaced from along the periphery of valve element.
Further, the cross section of the straight trough is circular arc.
It is further preferred that the straight trough has 3.
Wherein, the valve element is integrally manufactured.
Further, the material of the valve element is plastics
Compared with prior art, the utility model has the advantages that：
1. the utility model adds adjusting screw, when spring force deficiency, spring pair can be adjusted by adjusting screw
The support force of valve element, and then a reliable sealing is obtained, extend the service life of valve；
2. being conical surface seal between valve element and valve body, make sealing surface wider, improve the sealing property of grease pouring valve；
3. existing grease pouring valve, because the gap between steel ball valve body is smaller, so as to have impact on the circulation of medium, or even make
Into blocking, make unidirectional greasing defective valve；Taper is changed in the sealing surface of valve element, while is uniformly distributed at valve element circumference a plurality of straight
Groove, the circulation area of medium is added, improve the flow of media ability of unidirectional grease pouring valve；
4. existing grease pouring valve, steel ball is bonded to form sealing with valve body inner face, is a kind of sealing knot of metal to metal
Structure, shape metallic leak-proof structure under pressure, easily produce expendable deformation, cause seal failure；In the utility model
Valve core material is plastics, forms soft sealing structure of the valve element to valve body, overcomes metal sealing grade easy to wear and yielding and lacks
Point, improve the sealing reliability of grease pouring valve.

Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing, to this reality
It is further elaborated with new.
As shown in Fig. 2 a kind of unidirectional grease pouring valve disclosed in the utility model, including bonnet 1, valve body 2, valve element 3, spring 4
With adjusting screw 5, valve body 2 has greasing passage, and bonnet 1 is connected with the threaded one end of valve body 2 and covers the entrance of greasing passage, valve
Core 3 and spring 4 are located in greasing passage, are conical surface seal between valve element 3 and valve body 2, and the one end of spring 4 is pressed on adjusting screw 5,
The other end of spring 4 is withstood on valve element 3, and adjusting screw 5 coordinates located at the exit of greasing passage and with the screw thread of valve body 2, adjusts spiral shell
The medium through hole of axial direction is provided with nail 5, in order to the medium outflow in greasing passage.
Wherein, the one end of valve element 3 is conical structure, and the other end of valve element 3 is cylindrical structural, and conical structure is close with valve body
Front cover coordinates, and valve element 3 is integrally manufactured, and the material of valve element 3 is plastics.To improve the negotiability of medium, as shown in figure 3, in circle
