Abstract
The utility model relates to a one-way throttling buffer valve for an oil cylinder. The one-way throttling buffer valve for the oil cylinder consists of a cylinder head and a one-way throttling buffer valve which is installed on the cylinder head, wherein the one-way throttling buffer valve consists of a throttling valve core, a resetting spring, a one-way valve core, a locking nut and a valve sleeve; the throttling valve core is radially installed on the cylinder head through the valve sleeve; the valve sleeve is installed on the cylinder head in a thread engagement way; the throttling valve core is coaxially installed on the valve sleeve in a thread engagement way; the one-way valve core which is coaxial with the throttling valve core is installed at a valve hole of the cylinder head below the valve sleeve; the top end of the throttling valve core coaxially stretches into the one-way valve core; the resetting spring is installed between the one-way valve core and the throttling valve core; and the throttling valve core and the valve sleeve are locked by the locking nut. The one-way throttling buffer valve integrates a one-way valve and a throttling valve, is convenient, simple, practical, good in one-way throttling effect, good in linkage, low in cost and easy to manufacture, and is the one-way throttling buffer valve for the oil cylinder, which has strong functions.
Description
Technical field
The utility model belongs to the valve class, relates to trimmer valve, especially a kind of oil cylinder one-way throttle trimmer valve.
Background technique
At present, the control of the one-way throttle of oil cylinder buffering is that one-way valve, throttle valve are installed in respectively on the oil cylinder cylinder head, and control respectively causes manufacturing loaded down with trivial details thus, the cost height, and adjusting is inconvenient, can't realize interlock control.
By retrieval, do not find the publication document identical as yet with present patent application.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of oil cylinder one-way throttle trimmer valve of realizing throttling, single-way linkage control is provided.
The purpose of this utility model is achieved in that
A kind of oil cylinder one-way throttle trimmer valve, by cylinder head, the one-way throttle trimmer valve that is installed on the cylinder head constitutes, it is characterized in that: described one-way throttle trimmer valve is by throttling valve core, Returnning spring, nonreturn valve core, locking nut and valve pocket constitute, throttling valve core radially is installed on the cylinder head by valve pocket, valve pocket is installed on the cylinder head in the thread engagement mode, throttling valve core is coaxial to be installed on the valve pocket in the thread engagement mode, cylinder head valve opening position below valve pocket and the coaxial installation nonreturn valve core of throttling valve core, the top of this throttling valve core is coaxial to extend in the nonreturn valve core, between nonreturn valve core and throttling valve core Returnning spring is installed, throttling valve core and valve pocket adopt locking nut to be locked.
And described valve pocket and cylinder head adopt the sealing of O type circle, adopt the combination mat sealing between throttling valve core and the valve pocket.
Advantage of the present utility model and good effect are:
1, this trimmer valve has the characteristics of throttling, unidirectional two duty valves concurrently, and the size of may command flow is to realize the buffering of throttling and oil cylinder.
2, this trimmer valve is one with one-way valve, throttle valve and two, and is convenient, simple, practical, and one-way throttle control is effective, and linkage is good, and is with low cost, make simply, and be a kind of powerful oil cylinder one-way throttle trimmer valve.
Description of drawings

Fig. 2 is the structure enlarged diagram of the one-way throttle trimmer valve valve of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described; Need to prove: present embodiment is descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of oil cylinder one-way throttle trimmer valve, constitute by cylinder head 1, the one-way throttle trimmer valve 2 that is installed on the cylinder head, wherein the one-way throttle trimmer valve is made of throttling valve core 5, Returnning spring 4, nonreturn valve core 3, O type circle 6, combination mat sealing 7, locking nut 9 and valve pocket 8, throttling valve core radially is installed on the cylinder head by valve pocket, and valve pocket is installed on the cylinder head in the thread engagement mode and adopts the sealing of sealing O type circle; Throttling valve core is coaxial to be installed on the valve pocket in the thread engagement mode, adopts the combination mat sealing therebetween.
Cylinder head valve opening position below valve pocket and the coaxial installation nonreturn valve core of throttling valve core, the top of this throttling valve core is coaxial to extend in the nonreturn valve core, between nonreturn valve core and throttling valve core Returnning spring is installed, throttling valve core and valve pocket adopt locking nut to be locked.
The principle of this trimmer valve is:
Realize the unidirectional control of oilhole by nonreturn valve core and spring, when pressure oil from the oil-feed of A mouth, nonreturn valve core moves, and pressure oil is flowed out by A to B, when buffer cavity pressure oil from the oil-feed of B mouth, nonreturn valve core compresses, pressure oil flow to the A mouth through the gap of the throttling valve core nose-circle conical surface and oilhole, regulates the aperture size in the gap of the throttling valve core nose-circle conical surface and oilhole, get final product the size of control flow rate, to realize the buffering of throttling and oil cylinder.
Claims (2)
1. oil cylinder one-way throttle trimmer valve, by cylinder head, the one-way throttle trimmer valve that is installed on the cylinder head constitutes, it is characterized in that: described one-way throttle trimmer valve is by throttling valve core, Returnning spring, nonreturn valve core, locking nut and valve pocket constitute, throttling valve core radially is installed on the cylinder head by valve pocket, valve pocket is installed on the cylinder head in the thread engagement mode, throttling valve core is coaxial to be installed on the valve pocket in the thread engagement mode, cylinder head valve opening position below valve pocket and the coaxial installation nonreturn valve core of throttling valve core, the top of this throttling valve core is coaxial to extend in the nonreturn valve core, between nonreturn valve core and throttling valve core Returnning spring is installed, throttling valve core and valve pocket adopt locking nut to be locked.
