Abstract
The utility model relates to an insulating hydraulic high-pressure joint for a hydraulic pump station, comprising a right joint body and a left joint body, wherein a nylon separating sleeve is arranged between the right joint body and the left joint body; the two sides outside the nylon separating sleeve are sheathed with O-shaped sealing rings; and the outer side of the right joint body is sheathed with a nylon cap. The insulating hydraulic high-pressure joint has the beneficial effects that the two ends of the joint are mutually insulated, so that the characteristics of the original joint can be maintained, harmful current is prevented from passing through, and the possibility that the sealing rings are burnt by the current can be avoided.
Description
Technical field
The utility model relates to a kind of insulation high pressure joint, relates in particular to the insulation hydraulic pressure high pressure joint of a kind of hydraulic power unit.
Background technique
Hydraulic joint commonly used is carbon steel making and conduction, when it is used on equipment that some may be charged, because of electric leakage when steel pipe joint is passed to oil cylinder and hydrovalve, can burn out the rubber seal on oil cylinder and the valve and cause leakage of oil, thereby make the equipment can't proper functioning, even initiation fire.Especially in the electric arc furnaces hydraulic system, because of the low voltage of tens thousand of amperes in big electric current, charged being easy to is passed to oil cylinder and valve along oil pipe on the body of heater.
The model utility content
At above defective, the hydraulic power unit that the utility model provides a kind of joint two ends mutually insulated and can avoid seal ring to be burnt by electric current insulation hydraulic pressure high pressure joint is to solve many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
A kind of hydraulic power unit comprises right connector body, left fittings body with the high pressure joint of insulation hydraulic pressure, is provided with the nylon spacer between described right connector body and the left fittings body, and described nylon spacer both sides external is with the O RunddichtringO, and the external side of right connector is with the nylon cap.
Hydraulic power unit described in the utility model with the beneficial effect of insulation hydraulic pressure high pressure joint is: its joint two ends mutually insulated, both can keep the characteristic of original joint, can stop deleterious current to pass through again, avoided seal ring by electric current burn may.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the sectional view of the described hydraulic power unit of the utility model embodiment with the high pressure joint of insulation hydraulic pressure.
Among the figure:
1, right connector body; 2, left fittings body; 3, intermediate connector; 4, nylon spacer; 5, nylon cap; 6, O RunddichtringO.
Embodiment
As shown in Figure 1, the insulation hydraulic pressure high pressure joint of the described hydraulic power unit of the utility model embodiment, comprise right connector body 1, left fittings body 2 and the intermediate connector between the two 3, be provided with nylon spacer 4 between described right connector body 1 and the left fittings body 2, described nylon spacer 4 both sides external are with O RunddichtringO 6; Described right connector body 2 outsides are with nylon cap 5; Intermediate connector 3 is as a whole with two joint sports associations by screw thread.Because the nylon insulation all is set between right connector body 1 and other part, therefore left fittings body 2 keeps insulation with right connector body 1.
Claims (1)
