Abstract

The utility model discloses a pressure detection joint ball seal structure which comprises a pressure detection joint body, a cone valve body, a steel ball and a spring, wherein the steel ball and the spring are arranged in the pressure detection joint body, the steel ball is arranged at one end of the spring, a valve body through hole is formed in the cone valve body, an inner conical surface is arranged at one end of the valve body through hole, the steel ball is matched with the inner conical surface of the valve body through hole, one end of the cone valve body is connected and fixed on an inner hole in one end of the pressure detection joint body through valve body threads, the inner hole in the one end of the pressure detection joint body is a counter bore, a seal groove is formed in the end face of one end of the cone valve body, an O-shaped ring is arranged in the seal groove, and the O-shaped ring is closely attached to the end face of the counter bore. The pressure detection joint ball seal structure has the advantages that due to the structure, assembling is convenient, and meanwhile process requirements for components and parts are reduced; replacement of the steel ball and other components and parts is convenient; matching of the inner conical surface and the steel ball enables a pressure detection joint to be rapidly opened or closed; and the matching and sealing of the inner conical surface and the steel ball are good in centring effect, and seal reliability is effectively improved.

Description

Pressure measuring tie-in ball sealing configuration
Technical field
The utility model relates to a kind of pressure measuring tie-in ball sealing configuration.
Background technique
Self-styled valve is arranged in the pressure measuring tie-in, and owing to the effect of spring, self-styled valve cuts out when using separately; Just self-styled valve can be opened after the measurement flexible pipe of band thimble or measurement joint connect together, use and high pressure or low-pressure fluid systematic sampling and system pressure detection.But there is following defective in existing pressure measuring tie-in: 1, cone valve all is pressed into the pressure measuring tie-in body, and the part processing quality of fit requires high, the press-loading process complexity.2, can't dismantle after press-fiting, can't change inner seal.3, sealed steel ball self contering effect is relatively poor, and sealing reliability is relatively poor.
The model utility content
The purpose of this utility model is to overcome above shortcomings in the prior art, and a kind of reasonable in design is provided, and is easy to assembly, technology is simple, the pressure measuring tie-in ball sealing configuration of for convenience detach, good airproof performance.
The technical scheme in the invention for solving the above technical problem is: this pressure measuring tie-in ball sealing configuration, comprise the pressure measuring tie-in body, cone valve, steel ball and spring, steel ball and spring are arranged in the pressure measuring tie-in body, steel ball is arranged on an end of spring, cone valve offers valve hole, one end of this valve hole is provided with inner conical surface, the inner conical surface of steel ball and valve hole matches, it is characterized in that: an end of cone valve is threaded by valve body and is fixed on the end endoporus of pressure measuring tie-in body, the endoporus of described pressure measuring tie-in body one end is counter sink, the end face of cone valve one end offers seal groove, is provided with O shape circle in the sealing groove, and O shape circle is close to the end face of counter sink.
The inner conical surface of valve hole described in the utility model becomes 25-35 degree angle with the axle center of valve hole, the male cone (strobilus masculinus) of poppet valve core becomes 25-35 degree angle with the axle center of poppet valve core.
The intermediate section of cone valve described in the utility model is provided with shaft shoulder portion, and the valve body screw thread is arranged in the shaft shoulder portion.
The inner conical surface of valve hole described in the utility model becomes 30 degree angles with the axle center of valve hole.
The dual-side of the shaft shoulder described in the utility model portion is the hypotenuse shape.
The utility model compared with prior art has the following advantages and effect:
1. when installing, can successively spring and steel ball be put into the pressure measuring tie-in body, cone valve is screwed into the pressure measuring tie-in body by screw thread, and is not only easy to assembly, also reduced the technological requirement of component;
2. because employing is threaded, make cone valve to dismantle easily, change component such as steel ball;
3. adopting 30 ° of inner conical surfaces and steel to cooperate can make pressure measuring tie-in open or close fast;
4. adopt 30 ° of inner conical surfaces and steel to cooperate ball sealing centering effective, effectively improve the reliability of sealing;
5. the utility model can be used for the online pressure measurement of 40Mpa hydraulic system.
