Abstract
The utility model relates to a grease injection valve. The grease injection valve comprises a valve body, a valve cover and a screw. A hand wheel is arranged outside the screw. The valve body is fixedly arranged in the valve cover and provided with a storage chamber for storing sealing grease. The screw passes through the valve cover and is matched slidingly with the storage chamber. The screw is in threaded connection and match with the valve cover. An outlet communicated with the storage chamber is arranged at the lower end of the valve body. The outlet is an outlet cone-shaped face which reduces gradually from outside to inside. The outlet is internally provided with a steel ball which is linearly and hermetically matched with the outlet cone-shaped face. The front end of the screw is cone-shaped. The inner end of the outlet is provided with a sealing face matched with the cone-shaped face. At least two O-shaped seal rings are arranged on the outer wall of the screw. The grease injection valve provided by the utility model is reasonable in structural design, and the inner structure of the grease injection valve is designed with three seals, so that good sealing performance of the grease injection valve is ensured, and leakage of grease is avoided. The grease injection valve can be widely used conveniently.
Description
Technical field
The utility model relates to a kind of valve, especially a kind of grease pouring valve.
Background technique
At present, the grease pouring valve of domestic production is the sealing of single sealing hard sphere, the material that it is selected for use; Comprise and satisfied not operating conditions sealing life at high pressure or rugged environment; And structural design is not rigorous, in the process of greasing, has been easy to generate the phenomenon of " run, leak " grease, does not have the lubrication of grease to whole valve; Valve to integral body uses, and has produced very big negative influence.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned existing technology, and a kind of grease pouring valve is provided, and its structural design multi-sealing structure guarantees its good sealing property.
The utility model solves the technological scheme that its technical problem adopts: this grease pouring valve, comprise valve body, valve gap, screw rod, and screw rod is provided with handwheel outward; Valve body is fixed in the valve gap; Valve body is provided with the storing cavity that stores seal gease, wherein screw rod pass valve gap and with the storing cavity sealed sliding movingly, cooperate for being threaded between screw rod and the valve gap; The lower end of valve body is provided with the outlet that communicates with storing cavity; The outlet conical surface of outlet for diminishing gradually from outside to inside is provided with steel ball in the outlet, steel ball is linear sealing with the outlet conical surface and cooperates; Wherein the front end of screw rod is a conical surface, and the inner of outlet is provided with the sealing surface that is complementary with conical surface; Wherein the outer wall of screw rod is provided with twice O-ring seals at least.Grease pouring valve indoor design triple seal: at first, the linear sealing of the conical surface in steel ball and the valve outlet; Secondly, the conical surface of screw front end also reaches sealing with the valve body inner sealing surface; By the sealing of twice O-ring seals, O-ring seals guarantees to preserve good sealed sliding movingly between screw rod and the valve body at last.
Further, the sidewall of valve gap is provided with the fastening piece of roof pressure on valve body.This fastening piece can adopt fastening screw trip bolt, is threaded on the sidewall of valve gap and passes the sidewall roof pressure on valve body, avoid between valve body and the valve gap be connected loosening.
The outer wall of valve body is provided with outside thread, and the rear end of valve body is provided with buckle slot.When adopting grease gun to carry out greasing, remove valve gap, screw rod, connecing the buckle slot on buckle and the valve body soon or be threaded and carry out greasing with grease gun.
Be fixedly connected through pin between screw rod and the handwheel.
The effect that the utility model is useful is: the utility model reasonable in design, its internal structure design triple seal guarantees that grease pouring valve has good sealing property, prevents to run leakage of oil fat phenomenon and produces, and helps being widely used.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Description of reference numerals: valve body 1, outlet 2, outlet conical surface 2-1, steel ball 3, sealing surface 4, storing cavity 5, fastening piece 6, conical surface 7, O-ring seals 8, buckle slot 9, valve gap 10, screw rod 11, pin 12, handwheel 13, outside thread 14.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
With reference to accompanying drawing: this grease pouring valve, comprise valve body 1, valve gap 10, screw rod 11, be fixedly connected through pin 12 between the screw rod 11 outer handwheels 13 that are provided with, screw rod 11 and handwheel 13.Valve body 1 is fixed in the valve gap 10; Valve body 1 is provided with the storing cavity 5 that stores seal gease, wherein screw rod 11 pass valve gap 10 and with storing cavity 5 sealed sliding movingly, cooperate for being threaded between screw rod 11 and the valve gap 10; The lower end of valve body 1 is provided with the outlet 2 that communicates with storing cavity 5; The outlet conical surface 2-1 of outlet 2 for diminishing gradually from outside to inside is provided with steel ball 3 in the outlet 2, and steel ball 3 is linear with outlet conical surface 2-1 and is sealed and matched; Wherein the front end of screw rod 11 is a conical surface 7, and the inner of outlet 2 is provided with the sealing surface 4 that is complementary with conical surface 7; Wherein the outer wall of screw rod 11 is provided with twice O-ring seals 8 at least.The sidewall of valve gap 10 is provided with the fastening piece 6 of roof pressure on valve body 1.
This grease pouring valve can have multiple grease injecting mode:
First kind: through rotating screw bolt 11; Dwindle seal gease storing cavity 5; When the pressure of seal gease storing cavity 5 injects the pressure of seal gease position greater than needs, promote steel ball to front end, seal gease flows through injection valve sealing face or other cavity around steel ball; By last twice O-ring seals sealing, guarantee that grease pouring valve does not leak outside when carrying out greasing.
Second kind: adopt grease gun to carry out greasing; Wherein the outer wall of valve body 1 is provided with outside thread 14; The rear end of valve body 1 is provided with buckle slot 9, removes valve gap, screw rod, handwheel, the buckle slot 9 that connects buckle and valve body 1 soon of grease gun or valve body outside thread 14 is connected carries out greasing.
Though the utility model is through illustrating and describe with reference to preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
