A valve sleeve for a forklift comprises a main body, wherein the main body is of a cylindrical structure, a first inner hole is formed above the main body, a second inner hole is formed below the main body, a sealing groove is formed below the first inner hole, and a spacer ring is arranged between the sealing groove and the second inner hole; a plurality of oil through holes are respectively formed in the first inner hole and the second inner hole; a plurality of positioning holes are formed in the circumference of the main body in the upward direction. The utility model has simple and reasonable structure, convenient installation and positioning, correct positioning, high strength and quick installation, and can effectively prevent position deviation.
Description
Technical Field
The utility model relates to the technical field of hydraulic forklift parts, in particular to a valve sleeve for a forklift.
Background
The hydraulic valve is used to control the flow direction of oil in hydraulic system or regulate its pressure and flow rate, so it can be divided into three categories of directional valve, pressure valve and flow valve, the pressure valve and flow valve utilize the cross-section throttling action to control the pressure and flow rate of the system, and the directional valve utilizes the change of through-flow channel to control the flow direction of oil. They are usually used in combination with solenoid valves for remote control of the make and break of oil, gas and water pipe systems. It is commonly used for oil circuits of clamping, controlling, lubricating and the like. The machining precision requirement of the valve sleeve plays an important role, the existing valve sleeve is low in precision, position deviation is easy to occur during installation, the precision during installation is difficult to guarantee, and the structural strength is low.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a valve sleeve for a forklift, which has the advantages of reasonable structure, correct positioning and high strength, and overcomes the defects of the prior art.
A valve sleeve for a forklift comprises a main body, wherein the main body is of a cylindrical structure, a first inner hole is formed above the main body, a second inner hole is formed below the main body, a sealing groove is formed below the first inner hole, and a spacer ring is arranged between the sealing groove and the second inner hole; a plurality of oil through holes are respectively formed in the first inner hole and the second inner hole; a plurality of positioning holes are formed in the circumference of the main body in the upward direction. The utility model has simple and reasonable structure, convenient installation and positioning, correct positioning, high strength and quick installation, and can effectively prevent position deviation.
As a further improvement and complement to the above solution, the present invention also includes the following additional technical features:
the locating hole be the taper hole of big outside little inside, installation and dismantlement convenient and fast.
The main body, the first inner hole, the sealing groove, the spacer ring and the second inner hole are coaxial, so that high precision is guaranteed.
The valve sleeve is made of 40Cr, and is high in strength and wear-resistant.
The utility model can achieve the following beneficial effects: the utility model has simple and reasonable structure, convenient installation and positioning, correct positioning, high strength and quick installation, can effectively prevent position deviation and ensure the precision in installation.

Detailed Description
The following detailed description of embodiments of the utility model refers to the accompanying drawings.
As shown in fig. 1-2, the present invention is a valve sleeve for a fork lift truck.
The valve sleeve for the forklift comprises a main body 1, wherein the main body 1 is of a cylindrical structure, and chamfers are arranged at the upper end and the lower end of the main body 1. The main part 1 top is equipped with first hole 4, and the below is equipped with second hole 7, and first hole 4 below is equipped with seal groove 5, and seal groove 5 is the ring channel, and the internal diameter of seal groove 5 is greater than the diameter of first hole 4. A space ring 6 is arranged between the sealing groove 5 and the second inner hole 7, the space ring 6 is connected with the main body 1, and the strength is enhanced. A plurality of oil through holes 3 are respectively arranged on the first inner hole 4 and the second inner hole 7, and the oil through holes 3 penetrate through the main body 1 and the first inner hole 4 and the second inner hole 7. The main body 1 is provided with a plurality of positioning holes 2 in the circumferential direction.
Furthermore, the positioning holes 2 are taper holes with large outer portions and small inner portions, the positioning holes 2 are arranged on the main body 1 of the first inner hole 4, the positioning holes 2 are arranged in an upper group and a lower group, and each group is provided with more than 2 positioning holes.
Furthermore, the main body 1, the first inner hole 4, the sealing groove 5, the spacer ring 6 and the second inner hole 7 are coaxial.
Furthermore, the material of the valve sleeve is 40 Cr.
When the valve sleeve for the forklift is used, the excircle of the main body 1 is in clearance fit with the valve body, the clearance is generally between 0.02 and 0.04mm, the first inner hole 4 of the main body is in clearance fit with the valve core, the clearance is generally between 0.08 and 0.085mm, and the second inner hole 7 is matched with other related parts.
The above is the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, and variations and modifications made by those skilled in the art according to the design concept of the present invention should be considered to be within the scope of the present invention.
