Abstract

The utility model discloses a rotary joint, including rotary joint main part and valve ball, the rotary joint main part tip that is close to the valve ball is the arc with it adaptation. The utility model discloses utilize rotary joint main part and valve ball to form the sealed form of sphere for form stable zero clearance contact between the sealed face, when the check valve is in open position, the valve ball breaks away from with the sealed face of rotary joint main part, does not have wearing and tearing, and when the check valve was in closed condition, the valve ball contacted closely with the sealed face of rotary joint main part, formed stable seal structure, improved sealed effect.

Description

Rotary joint

Technical Field

The utility model relates to a joint seal structure technical field, more specifically the utility model relates to a rotary joint that says so.

Background

The double-hose diaphragm pump converts the rotation motion of a driving shaft into the reciprocating motion of a piston, reduces the speed to the stroke times required by the piston, can drive a certain amount of hydraulic oil in a pump head by the reciprocating motion of the piston in a hydraulic cylinder, and enables a main hose-diaphragm and an auxiliary hose-diaphragm to be jointly extruded at the same time due to the change of volume. Due to the special structure of the double hoses, the double hoses are always contracted and expanded in the same direction and shape, and light oil transmission fluid between the main hose and the auxiliary hose-diaphragm directly presses the conveyed medium. When moving forward, the main hose-diaphragm in the pump hydraulic chamber squeezes the delivered fluid out through the outlet valve into the outlet line, where the delivered fluid undergoes pressure and flow changes. In the whole process, the inlet and outlet one-way valves of the operation process pump play a vital role, and the one-way valves are generally composed of valve balls, a shell and a rotary joint, wherein the rotary joint plays a key sealing role.

However, the existing rotary joint often causes the phenomenon of leakage of process media due to the defect of sealing in the using process, thereby not only wasting resources, but also occupying larger maintenance cost.

Therefore, it is an urgent problem to provide a rotary joint with good sealing performance.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a rotary joint forms stable seal structure, improves sealed effect.

In order to realize the purpose, the utility model adopts the following technical scheme:

a rotary joint comprises a rotary joint body and a valve ball, wherein the end part, close to the valve ball, of the rotary joint body is in an arc shape matched with the rotary joint body.

Through taking above scheme, the beneficial effects of the utility model are that:

utilize rotary joint main part and valve ball to form the spherical surface sealed form for stable zero clearance contact has been formed between the sealed face, and when the check valve was in the open position, the valve ball broke away from with the sealed face of rotary joint main part, and is not worn and torn, and when the check valve was in the closed condition, the valve ball contacted closely with the sealed face of rotary joint main part, formed stable seal structure, improved sealed effect.

Furthermore, the rotary joint main body is made of dual-phase steel 2205.

The beneficial effect that adopts above-mentioned further technical scheme to produce is, and intensity is big, and is corrosion-resistant, can reduce maintenance personal's work load, has prolonged the life of equipment and has practiced thrift company's economic cost.

Therefore, the utility model provides a rotary joint compares with prior art, the utility model discloses make the fan can reach the effect of long period steady operation, prolong the life of fan, also alleviate maintenance personal's intensity of labour simultaneously, practice thrift the cost to improve social resource's utilization ratio.
